How to give a variable path for GetFolder in VBScript? | <p>This script basically goes to a folder and list all the files in that folder and output it in a txt file. Now instead of defining the folder path I want it to use the txt file that contains a bunch of folder paths in it and I want to loop that txt file. How can I do this?</p>
<pre><code>Dim fso
Dim ObjFolder
Dim ObjOutFile
Dim ObjFiles
Dim ObjFile
'Creating File System Object
Set fso = CreateObject("Scripting.FileSystemObject")
'Getting the Folder Object
Set ObjFolder = fso.GetFolder("C:\Users\Susan\Desktop\Anime\ova")
'Creating an Output File to write the File Names
Set ObjOutFile = fso.CreateTextFile("C:\Users\Susan\Documents\iMacros\Macros\WindowsFiles.txt")
'Getting the list of Files
Set ObjFiles = ObjFolder.Files
'Writing Name and Path of each File to Output File
For Each ObjFile In ObjFiles
ObjOutFile.WriteLine(ObjFile.Path)
Next
ObjOutFile.Close

Send two argument using map and lambda functions and return two values | <p>I would like to send two arguments within a function and receive two values as well </p>
<p>I want to modify this code so that I code be able to send two arguments and receive two as well</p>
<pre><code>list_value = [ 1, 2,0,-1,-9,2,3,5,4,6,7,8,9,0,1,50]
hnd = map(lambda (valua): function_f(valua), list_value)
</code></pre>
<p>function_f is a function return one number either 1 or 0.</p>
<p>The above code can do the job when sending one argument but I want to send two instead of.
the first argument of the required function is list_value and the second argument is a model "net model train it using caffe"</p>
<p>so I would like to write a function that can do the same job of the previous function but returning two arguments one is [0 or 1] and the other is a modified model which this function has modified.</p> | 0 |
What will happen to the SharedPreferences on update an Android App? | <p>I've stored user settings in the SharedPreferences in my App. What will happen with the SharedPreferences when I update the App via Google Play Store to a new version of the App?</p>
<p>Will the SharedPrefernces still be there after the update or will they be deleted?</p>
<p>So far I haven't found an answer on the web or Stackoverflow.</p>
<p>Can you point me to some links they describe this process?</p>
<p><strong>Edit:</strong>
Meanwhile I found an other answer as well: <a href="https://stackoverflow.com/questions/7103453/sharedpreferences-update-unisntall">SharedPreferences behaviour on Update/Uninstall</a></p>
<p><strong>Edit 2:</strong>
Time past quite a bit when I first asked this question I recently learned that since Android 6.0 (API 23) it is also possible to use the auto backup functionality to <em>store</em> your shared preferences as described by <a href="https://developer.android.com/guide/topics/data/autobackup.html#EnablingAutoBackup" rel="nofollow noreferrer">Google here</a>.</p>
<p>Just add the <code><application android:allowBackup="true" ... > </code> in your <code>AndroidManifest.xml</code> file.</p> | 0 |
python- constant dictionary? | <p>I simply generate a list of python dictionaries, and then serialize it to json.<br>
Basically my code is a loop where I do something like: </p>
<pre><code>ls.append({..values..})
</code></pre>
<p>I don't change the dictionaries after this. </p>
<p>The question, is there a constant dictionary in python, obviously the point here is memory, since I know dictionary takes more memory than a list. I simply need the structure of <code>{key:value}</code> for json, not the other features of the dictionary.</p>
<p>Just curious if I can optimize my code a bit.</p> | 0 |

CSS Text Align Bottom of Container | <p>I have a header which has a large image floated on one side, and a small paragraph of text on the other side.

How create a batch file that opens a 32bit cmd prompt as Admin to run another batch file | <p>I have a batch file that I currently have to do the following to run:</p>
<ol>
<li>Open SYSWOW64\cmd.exe as admininstrator (it's a 32bit application)</li>
<li>cd c:\mybatchfilelocation\</li>
<li>then run my batch file batchfile.bat</li>
</ol>
<p>I'd like to just be able to run one batch as admin that automatically opens the SYSWOW64\cmd.exe as administrator (prompting for admin username and password is ok) and then have that run my batchfile.bat</p>
<p>I've seen where you can do it if you pre-specify the /user:machinename\administor in the batch file before running it and it only prompts for password but this needs to be deployed to customers and I can't rely on them editing the file. I need it to run with prompts when input is required by them.</p>
<p><strong>UPDATE</strong></p>
<p>Thanks to Bill, I no longer need to worry about the SYSWOW64 part. I only need to be able to figure out how to have a batch file open a cmd prompt as an administrator and have that cmd run another batch file in that same directory.</p> | 0 |

Problems with Chinese Fonts in iText-PDF on Windows Machines | <p>I'm using a Ubuntu-PC to create PDFs with iText which are partly in Chinese. To read them I use Evince. So far there were hardly any problems</p>
<p>On my PC I tried the following three BaseFonts and they worked with success:</p>
<pre><code>bf = BaseFont.createFont("MSungStd-Light", "UniCNS-UCS2-H", BaseFont.NOT_EMBEDDED);
bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
bf = BaseFont.createFont("MSung-Light","UniCNS-UCS2-H", BaseFont.NOT_EMBEDDED);
</code></pre>
<p>Unfortunately in the moment the final PDF is opened on Windows with the Acrobat-Reader the document can't be displayed correctly any more.</p>
<p>After I googled the Fonts to get a solution I came to that Forum where the problem is explained in an understandable way (Here MSung-Light was used): <a href="http://community.jaspersoft.com/questions/531457/chinese-font-cannot-be-seen" rel="nofollow">http://community.jaspersoft.com/questions/531457/chinese-font-cannot-be-seen</a></p>
<blockquote>
<p>You are using a built-in Chinese font in PDF. I'm not sure about the
ability of this font to support both English and Chinese, or mixed
language anyway.</p>
<p>The advantage of using an Acrobat Reader built-in font is that it
produces smaller PDF files, because it relies on those fonts being
available on the client machine that display the PDF, through the
pre-installed Acribat Asian Font Pack.</p>
<p>However, using the PDF built-in fonts has some disadvantages that were
discovered through testing on different machines, when we investegated
a similar problem related to a built-in Korean font.</p>
</blockquote>
<p>What should I do about it?
It's not so important to be able to copy the Chinese letters. Can iText convert a paragraph to an image? Or are there any better solutions?</p> | 0 |

What should I pass for the WWW-Authenticate header on 401s if I'm only using OpenID? | <p>The HTTP spec states:</p>
<blockquote>
<p><strong>10.4.2 401 Unauthorized</strong></p>
<p>The request requires user authentication. The response MUST include a WWW-Authenticate
header field (section 14.47) containing a challenge applicable to the requested resource. </p>
</blockquote>
<p>If the only login scheme I support is OpenID (or CAS, or OAuth tokens, &c.), what should I put in this field? That is, how do I indicate that the client needs to <em>pre-authenticate</em> and create a session rather than try to send credentials along with each request?</p>
<p>Before you answer, "don't send a 401; send a 3xx redirecting to the OpenID login page," what about for non-HTML clients? How, for example, would Stack Overflow do an API that my custom software could interact with?</p> | 0 |

Detect in Javascript when HTML5 <video> loop restarts? | <p>I have a looping HTML5 video using <code><video loop="true"></code>, and I want to know when the video loops. The event listener <code>play</code> only fires when the video is started initially, and <code>ended</code> never fires. </p>

<pre><code><video autoplay="true" loop="true" muted="true">

var t = document.getElementById('Video-Time');
v.addEventListener('timeupdate',function(event){
t.innerHTML = v.currentTime;
if ( v.currentTime <= 0 ) { console.log("Beginning!"); } // It does trigger when looping, surprisingly
},false);
v.addEventListener('play', function () {
console.log("play!"); // Only triggered when the video initially starts playing, not when the loop restarts

UIGraphicsGetCurrentContext vs UIGraphicsBeginImageContext/UIGraphicsEndImageContext | <p>I am new to these parts of iOS API and here are some questions that are causing an infinite loop in my mind</p>
<ol>
<li><p>Why does ..BeginImageContext have a size but ..GetCurrentContext does not have a size? If ..GetCurrentContext does not have a size, where does it draw? What are the bounds?</p></li>
<li><p>Why did they have to have two contexts, one for image and one for general graphics? Isn't an image context already a graphic context? What was the reason for the separation (I am trying to know what I don't know)</p></li>

Multipart requests/responses java | <p>I have a task to implement sending of http multipart request and interpreting http multipart response. I decided to start from the response as I just have to receive a response and parse it. I have not that much experience with java and even less with HTTP and that is why I read some articles and other stuff on the topic but I have still some open questions:</p>
<ol>
<li>As far as I understood the content type multipart is used for file upload, sending email attachments, etc. The most posts that I found in google were actully for file upload using multipart/form-data. In what other cases is this content-type used?</li>
<li>I decided to start with the HTTP multipart response, but I realised I have no idea what I have to do in order to receive a response with such a content type. How shall my request look like, what shall I request with this request? I just want to write a simple program in java, which sends an HTTP request to a server and the response that is received is with content-type multipart.</li>
</ol>
<p>It would be nice if someone can clarify these things to me because I think I have misunderstood something.</p>
<p>Thank you in advance!</p> | 0 |
Display image from URL, Swift 4.2 | <p>I am a fairly decent Objective C developer, and I am now learning Swift (of which I am finding quite difficult, not only because of new concepts, such as optionals, but also because Swift is continually evolving, and much of the available tutorials are severely outdated).</p>
<p>Currently I am trying parse a JSON from a url into an NSDictionary and then use one of its value to display an image (which is also a url). Something like this:</p>
<hr>
<p>URL -> NSDictionary -> init UIImage from url -> display UIImage in UIImageView</p>
<hr>
<p>This is quite easy in Objective C (and there may even be a shorter answer):</p>
<pre><code>NSURL *url = [NSURL URLWithString:@"https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY"];
NSData *apodData = [NSData dataWithContentsOfURL:url];
NSDictionary *apodDict = [NSJSONSerialization JSONObjectWithData:apodData options:0 error:nil];
</code></pre>
<p>The above code snippet gives me back a standard NSDictionary, in which I can refer to the "url" key to get the address of the image I want to display:</p>
<hr>
<p>"url" : "<a href="https://apod.nasa.gov/apod/image/1811/hillpan_apollo15_4000.jpg" rel="nofollow noreferrer">https://apod.nasa.gov/apod/image/1811/hillpan_apollo15_4000.jpg</a>"</p>
<hr>
<p>This I then convert into a UIImage and give it to a UIImageView:</p>
<pre><code>NSURL *imageURL = [NSURL URLWithString: [apodDict objectForKey:@"url"]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
UIImage *apodImage = [UIImage imageWithData:imageData];
UIImageView *apodView = [[UIImageView alloc] initWithImage: apodImage];
</code></pre>
<p>Now, I am basically trying to replicate the above Objective C code in Swift but continuously run into walls. I have tried several tutorials (one of which actually did the exact same thing: display a NASA image), as well as find a few stack overflow answers but none could help because they are either outdated or they do things differently than what I need.</p>
<p>So, I would like to ask the community to provide the Swift 4 code for the these problems:</p>
<pre><code>1. Convert data from url into a Dictionary
2. Use key:value pair from dict to get url to display an image
</code></pre>
<p>If it is not too much already, I would also like to ask for detailed descriptions alongside the code because I would like the answer to be the one comprehensive "tutorial" for this task that I believe is currently not available anywhere.</p>
<p>Thank you!</p> | 0 |

How to create a wireless hotspot from 3G connection in iOS | <p>If I wanted to, how would I create an app like <a href="http://intelliborn.com/mywi.html" rel="noreferrer">MyWi</a>, i.e. a wifi tethering app? What are the steps to achieve this functionality? What frameworks/libraries would I need to use? </p>
<p>The goal is not to try to get this app into the app store, but to have it for personal use, and provide it to others.</p>
<p>EDIT:
Nick pointed out the <a href="http://www.youtube.com/watch?v=IlarDCHCyXA" rel="noreferrer">HandyLight app</a>, an app that provided tethering capability disguised as a flashlight. So, it is possible to provide tethering functionality via a third-party app on a non-jailbroken phone. So how is this done?</p>

Host is not allowed to connect to this MySQL server for client-server application | <p>I just exported my tables from one web host to another (AWS).
Thinking everything would go smoothly (yeah right), well, everything that can go wrong has gone wrong.</p>
<p>I get this error when trying to query my database (which I didn't get before):</p>
<p><code>SQLSTATE[HY000] [1130] Host '<my ip address>' is not allowed to connect to this MySQL server</code></p>
<p>This is the same error from this post:</p>
<p><a href="https://stackoverflow.com/questions/1559955/host-xxx-xx-xxx-xxx-is-not-allowed-to-connect-to-this-mysql-server">Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server</a></p>
<p>The solution in that post seems to revolve around having an administrative user. I am developing a chat application so every user needs to access the server (so I'm sure it's a bad idea to give them all administrative privileges).
The answer by Pascal in that link says, <code>If you are using mysql for a client/server application, prefer a subnet address.</code> but I honestly don't understand what he means by that. And because of the amount of solutions, I'm not exactly sure which one I should follow based on my case.</p>

How to find all assets of a type? | <p>In my Unity project a have several instanced of the class ArmourType (these are assets, scriptable objects). I'm trying to show these in a dropdown list in the inspector, and this works. However, I use </p>
<pre><code>List<ArmourType> armourTypes = Resources.FindObjectsOfTypeAll<ArmourType>();
</code></pre>
<p>to find all these instances. This only finds the objects that are loaded into memory, so occasionally it only finds some of the required assets. This is documented, so isn't a bug, but very annoying at times.</p>
<p>So my question is, is there a different way of getting all these assets that does return those that aren't loaded into memory? Or perhaps is there a way to make Unity load the assets when they are looked for?</p>

How to update version of Microsoft.NETCore.App SDK in VS 2017 | <p>I have ASP.NET Core API project which was initially developed using VS 2015. I installed VS 2017 and let it convert the project.<br />
Then i goto Project Properties -> Application ->Target framework and change the target framework to .NETCoreApp 1.1.</p>
<p>as soon as i do that i get 2 errors</p>
<blockquote>
<p>Error One or more projects are incompatible with
.NETCoreApp,Version=v1.0.</p>
<p>Error Project Api is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Project Api supports: netcoreapp1.1
(.NETCoreApp,Version=v1.1)</p>
</blockquote>
<p>when i checked <code>Dependencies -> SDK -> Microsoft.NETCore.App -> Properties</code> it shows version <code>1.0.4</code> and <code>SDK Root</code> to <code>C:\Users\username\.nuget\packages\microsoft.netcore.app\1.0.4</code></p>
<p>I have already installed <code>Microsoft.NETCore.App</code> SDK version <code>1.1.2</code> on my machine.</p>
<p>When i goto Nuget Package Manager to update SDK version, it shows its <code>Autoreferenced</code> and update button is disabled.</p>
<p>How do i update project's SDK's version to <code>1.1.2</code>?</p>
<p>Also why VS studio reference SDK from <code>C:\Users\username\.nuget\packages\microsoft.netcore.app</code> instead of from <code>C:\Program Files\dotnet\shared\Microsoft.NETCore.App\1.1.2</code></p>
<p><strong>Update 1</strong></p>
<p>Actually <code>1.1.2</code> is not SDK version. <a href="https://www.microsoft.com/net/download/core" rel="noreferrer">As of 7/20/2017</a> the latest SDK version is <code>1.0.4</code> and Runtime version is <code>1.1.2</code> On my machine I have <code>C:\Program Files\dotnet\sdk\1.0.4</code> SDK and <code>C:\Program Files\dotnet\shared\Microsoft.NETCore.App\1.1.2</code> runtime installed.</p>
<p>So as i mentioned erlier, when i open converted project in VS 2017, I see Dependencies -> SDK ->Microsoft.NETCore.App - Properties version is <code>1.0.4</code> and SDK Root is <code>C:\Users\username\.nuget\packages\microsoft.netcore.app\1.0.4</code></p>
<p>Now I added new project in the same solution, however new project's Dependencies -> SDK ->Microsoft.NETCore.App -> Properties version is 1.1.2 and SDK root <code>C:\Users\username\.nuget\packages\microsoft.netcore.app\1.1.2</code></p>
<p>I am not sure which is correct here, the SDK version of the converted project or SDK version of the newly added project?</p>
<p>Infact if create a brand new project in VS 2017 i see its Dependencies -> SDK ->Microsoft.NETCore.App -> Properties version is 1.1.2</p>
<p><code>1.1.2</code> SDK not even SDK available. Why VS 2017 shows runtime version as SDK version</p>
<p>is this a bug in VS 2017?</p> | 0 |
How can I *only* get the number of bytes available on a disk in bash? | <p><code>df</code> does a great job for an overview. But what if I want to set a variable in a shell script to the number of bytes available on a disk?</p>
<p>Example:</p>
<pre><code>$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda 1111111111 2222222 33333333 10% /
tmpfs 44444444 555 66666666 1% /dev/shm
</code></pre>
<p>But I just want to return <code>33333333</code> (bytes available on <code>/</code>), not the whole <code>df</code> output.</p> | 0 |

Ways to extend Array object in javascript | <p>i try to extend Array object in javascript with some user friendly methods like Array.Add() instead Array.push() etc...</p>
<p>i implement 3 ways to do this.
unfortunetly the 3rd way is not working and i want to ask why? and how to do it work.</p>
<pre><code>//------------- 1st way
Array.prototype.Add=function(element){
this.push(element);
};
var list1 = new Array();
list1.Add("Hello world");
alert(list1[0]);
//------------- 2nd way
function Array2 () {
//some other properties and methods
};
Array2.prototype = new Array;
Array2.prototype.Add = function(element){
this.push(element);
};
var list2 = new Array2;
list2.Add(123);
alert(list2[0]);
//------------- 3rd way
function Array3 () {
this.prototype = new Array;
this.Add = function(element){
this.push(element);
};
};
var list3 = new Array3;
list3.Add(456); //push is not a function
alert(list3[0]); // undefined
</code></pre>
<p>in 3rd way i want to extend the Array object internally Array3 class.
How to do this so not to get "push is not a function" and "undefined"?</p>
<p>Here i add a 4th way.</p>
<pre><code>//------------- 4th way
function Array4 () {
//some other properties and methods
this.Add = function(element){
this.push(element);
};
};
Array4.prototype = new Array();
var list4 = new Array4();
list4.Add(789);
alert(list4[0]);
</code></pre>
<p>Here again i have to use prototype.
I hoped to avoid to use extra lines outside class constructor as Array4.prototype.
I wanted to have a compact defined class with all pieces in one place.
But i think i cant do it otherwise.</p> | 0 |

Converting hours in decimal format | <p>I've tried mutliple solutions to this problem but I can't seem to get it.</p>
<p>I have time in decimal format, which is in hours. I want to make it much cleaner by changing it into a DD:HH:MM:SS format.</p>
<h2>Example:</h2>
<p><strike>10.89 hours == 10 hours, 53 minutes, 40 seconds</strike></p>
<p><strong>EDIT</strong>: 10.894945454545455 == 10 hours, 53 minutes, 40 seconds</p>
<h2>What I've tried:</h2>
<pre><code>int hours = (int) ((finalBuildTime) % 1);
int minutes = (int) ((finalBuildTime * (60*60)) % 60);
int seconds = (int) ((finalBuildTime * 3600) % 60);
return String.format("%s(h) %s(m) %s(s)", hours, minutes, seconds);
</code></pre>
<p>Which returned: <code>0(h) 41(m) 41(s)</code></p>

Selection of First L Items of ArrayList of size N > L and Insertion to Another ArrayList in Java | <p>I have an ArrayList l1 of size N and another l2 of size L < N. I want to put the L first items of l1 to l2. I thought to use the for loop of type for(Object obj : l1) to scan my list of size N and then use l2.add(obj) to add elements on l2, but I am not sure if when I reach the max size of l2 (i.e. L) stops inserting items or continues.</p>
<p>Could somebody suggest me a way to do that? Thanx</p> | 0 |
Null Pointer Exception when setting LayoutParams | <p>I created button in activity programmaticaly, not in xml file.

Implementing a slider (SeekBar) in Android | <p>I want to implement a slider, which is basically two lines, one vertical and one horizontal, crossing where the screen is touched. I have managed to make one but I have to issues:</p>

bytes/hexa to human readable value? | <p>I want to learn packet decoder processing using <a href="http://www.code.google.com/p/dpkt" rel="nofollow">dpkt</a>. On the site, I saw the following example code:</p>
<pre><code>>>> from dpkt.ip import IP
>>> from dpkt.icmp import ICMP
>>> ip = IP(src='\x01\x02\x03\x04', dst='\x05\x06\x07\x08', p=1)
>>> ip.v4
>>> ip.src
'\x01\x02\x03\x04'
>>> ip.data
''
>>>
>>> icmp = ICMP(type=8, data=ICMP.Echo(id=123, seq=1, data='foobar'))
>>> icmp
ICMP(type=8, data=Echo(id=123, seq=1, data='foobar'))
>>> len(icmp)
14
>>> ip.data = icmp
>>> ip.len += len(ip.data)
>>> ip
IP(src='\x01\x02\x03\x04', dst='\x05\x06\x07\x08', len=34, p=1, data=ICMP(type=8, data=Echo(id=123, seq=1, data='foobar')))

<p>I'm confused with lines that are using hexa such as:</p>
<pre><code>ip = IP(src='\x01\x02\x03\x04', dst='\x05\x06\x07\x08', p=1)
</code></pre>
<p>What is the meaning of "\x01\x02\x03\x04" and "\x05\x06\x07\x08"? Is it possible to convert strings like these to something more human-readable?</p> | 0 |

How can I insert a newline into a TextBlock without XAML? | <p>I have created a WPF <code>TextBlock</code> inside a <code>Label</code> <strong>in code</strong> (XAML is not possible in my case) as follows:</p>
<pre><code>Label l = new Label();
TextBlock tb = new TextBlock();
l.Content = tb;
</code></pre>
<p>I then come to a situation where I need to set the <code>.Text</code> property of <code>TextBlock</code> containing a new line, such as:</p>
<pre><code>tb.Text = "Hello\nWould you please just work?";
</code></pre>
<p>I have tried numerous encodings (HTML encoding, ASCII encoding, etc.) of various newline combinations (carriage return, linefeed, carriage return plus linefeed, linefeed plus carriage return, double linefeed, double carriage return, etc... ad nauseum). </p>
<ul>
<li>Answers should contain <em>absolutely no XAML</em>.</li>
<li>Answers should assume that the original objects were created using C# code and <strong>not</strong> XAML.</li>
<li>Answers should not refer to <em>binding</em> of WPF properties. No binding is being used. The "Text" property of the "TextBlock" object is being <strong>set</strong>. The newline <em>must</em> be inserted <em>there</em>.</li>
</ul>
<p>If this is impossible, please let me know how I can programmatically add newlines by dynamically replacing each newline in an arbitrary input <code>String</code> into a <code>LineBreak</code> object (or whatever is needed to get this working). The input <code>String</code> will have arbitrary (readable text) contents that I am unable to anticipate in advance because the text itself is dynamic (user-defined); the source strings will have the linefeed character (aka LF, aka <code>\n</code>) but I can easily replace that with whatever is needed.</p>
<p>Also, if it is easier to do this with a <code>Label</code> directly rather than a <code>TextBlock</code> in a <code>Label</code>, that is good too -- I can use that. I just need a control with automatic plain text line wrapping.</p> | 0 |
how can I used the “pefile.py” to get file(.exe) version | <p>I want to used python to get the executed file version, and i know the <a href="http://code.google.com/p/pefile/" rel="nofollow noreferrer">pefile.py</a></p>

Load external JS from bookmarklet? | <p>How can I load an external JavaScript file using a bookmarklet? This would overcome the URL length limitations of IE and generally keep things cleaner.</p> | 0 |
When to use ref and when it is not necessary in C# | <p>I have a object that is my in memory state of the program and also have some other worker functions that I pass the object to to modify the state. I have been passing it by ref to the worker functions. However I came across the following function.</p>
<pre><code>byte[] received_s = new byte[2048];
IPEndPoint tmpIpEndPoint = new IPEndPoint(IPAddress.Any, UdpPort_msg);
EndPoint remoteEP = (tmpIpEndPoint);
int sz = soUdp_msg.ReceiveFrom(received_s, ref remoteEP);
</code></pre>
<p>It confuses me because both <code>received_s</code> and <code>remoteEP</code> are returning stuff from the function. Why does <code>remoteEP</code> need a <code>ref</code> and <code>received_s</code> does not?</p>
<p>I am also a c programmer so I am having a problem getting pointers out of my head.</p>
<p>Edit:
It looks like that objects in C# are pointers to the object under the hood. So when you pass an object to a function you can then modify the object contents through the pointer and the only thing passed to the function is the pointer to the object so the object itself is not being copied. You use ref or out if you want to be able to switch out or create a new object in the function which is like a double pointer. </p> | 0 |
Wrap a delegate in an IEqualityComparer | <p>Several Linq.Enumerable functions take an <code>IEqualityComparer<T></code>. Is there a convenient wrapper class that adapts a <code>delegate(T,T)=>bool</code> to implement <code>IEqualityComparer<T></code>? It's easy enough to write one (if your ignore problems with defining a correct hashcode), but I'd like to know if there is an out-of-the-box solution.</p>
<p>Specifically, I want to do set operations on <code>Dictionary</code>s, using only the Keys to define membership (while retaining the values according to different rules).</p> | 0 |

Android mobile user agent? | <p>I'm currently making an android application for a forum, basically it just loads the website in a webview and that works fine and all, but I'm trying to add an option to view the full site or the mobile site. </p>
<p>I got it working by just making a boolean BrowserType which when set to true, loads the mobile site in the webview, and when set to false, loads the full page. I already have it working and everything, the full site loads and I jsut have the user agent as "Chrome", and I set the mobile user agent to "Mobile", but that doesn't work, what am I supposed to use as the user agent for mobile? Just for reference, this is the method I'm using:</p>
<pre><code>myWebView.getSettings().setUserAgentString("Chrome");
</code></pre>
<p>Then for the mobile one instead of "Chrome", I used "Mobile". What is the correct user agent for mobile?</p> | 0 |

dynamically changing height of #container div in flexslider | <p>I'm working with flexslider and the container div has a background image that acts like a border set to the bottom of it. What I need to do is get the container div to be responsive like the actual flexslider div. So when you shrink the window from right to left, the height of the container div should change height, if that makes sense. Dimensions of the images are 1680x748. And currently the height of the container div is 805px and the width is set to 100%. So the width doesn't matter. Just need to change the height.</p> | 0 |

WPF Databinding With A Collection Object | <p>I have a simple class as defined below:</p>
<pre><code>public class Person

string _name;

set { _id = value; }
}
public string Name
{
get { return _name; }
set { _name = value; }
}

<pre><code> public class People : ObservableCollection<Person>

<p>In XAML, I have myself a ListView that I would like to populate a ListViewItem (consisting of a textblock) for each item in the "People" object as it gets updated from the database. I would also like that textblock to bind to the "Name" property of the Person object.</p>
<p>I thought at first that I could do this:</p>
<pre><code>lstPeople.DataContext = objPeople;
</code></pre>
<p>where lstPeople is my ListView control in my XAML, but that of course does nothing. I've found TONS of examples online where people through XAML create an object and then bind to it through their XAML; but not one where we bind to an instantiated object and re-draw accordingly.</p>
<p>Could someone please give me a few pointers on:</p>
<p>A) How to bind a ListView control to my instantiated "People" collection object?</p>
<p>B) How might I apply a template to my ListView to format it for the objects in the collection?</p>
<p>Even links to a decent example (not one operating on an object declared in XAML please) would be appreciated.</p> | 0 |

Add tags when creating product in Magento? | <p>The "Product Tags" tab would only appear after a product has been created. Even then, there doesn't seem a way to add tags to a product - it only displays them when you are editing the product and I see only "Reset Filter" and "Search" buttons.</p>

<p>Is there any way to add tags to products when creating them? Just like you can specify tags when you are creating blog posts in WordPress.

<p><a href="https://i.stack.imgur.com/UZJuB.png" rel="noreferrer"><img src="https://i.stack.imgur.com/UZJuB.png" alt="Wrong position"></a></p>
<p>So the idea is to stop keeping moving once the limit (left as well as right) is reached. I tried checking if <code>_value < 0</code>, but it didn't work since It seems to be an offset, not a position.</p>
<p>Well any help will be appreciated.</p> | 0 |
