Asp.Net 4.0 gridview to show Display attribute value
|
<p>I have been displaying list of some class in gridview with AutoGenerateColumns = true.</p>
<p>The class has nearly 70+ properties.</p>
<p>Now I need to change the column header of the gridview. For example, class has property called "ProductName" but in the gridview I just need to show "Name".</p>
<p>One way is to remove AutoGenerateColumns and denote everything as boundfield. But it is too much of manual coding... rather a data entry!</p>
<p>I was thinking to use Display attribute of the class property to be shown as the header column in gridview. </p>
<pre><code>[Display(Name="Product")] public string ProdcutName { get; set;}
</code></pre>
<p>Is there any way to use Display attribute in Gridview?</p>
<p>Also suggest something else also... </p>

What does the abbreviation “ccb" stand for when used in stream reading
|
<p>I am not native English. I am often curious about variable's real meaning when it was named in shortening. I think that may help me to understand better of the code. For example, when overriding the operator, the lhs and rhs are often used. Once I was very exciting to find out that lhs means "left hand side" and rhs means right hand side. I like the naming.</p>
<p>I see the "ccb" many times, but I could not figure out what the words behind are. I am so curious that I now register to stackoverflow and post it here. Here is the code that uses the "ccb" variable naming:</p>
<pre><code>// the below code is in a custom home-brewn chunked stream reader
public override int Read(byte[] buffer, int offset, int ccbToRead)
{
int ccbRead = StreamUtils.ReadBytes(m_s, buffer, offset, Math.Min(ccbToRead, m_ccbCurrChunkRemaining));
m_ccbCurrChunkRemaining -= ccbRead;
return ccbRead;
}
</code></pre>

Check for an empty map
|
<p>I'm having an interesting issue that I'm sure is easily explained, but the explanation is eluding me.</p>
<p>An undefined or null object in javascript is equal to false.
</p>
<pre><code>var x;
alert(!x); //returns true
alert(x==true); //returns false
</code></pre>
<p>What about an empty array object? Is that the equivalent of true or false?</p>
<pre><code>var x = [];
alert (x==true); //returns false
alert (!x); //returns false
</code></pre>
<p>If it is equivalent to true, how do I check if it's non-empty? I was hoping to do</p>
<pre><code>if (!x) {
//do stuff
}
</code></pre>
<p>I tried checking <code>x.length</code>, but I'm using this object as a map:</p>
<pre><code>var x = [];
alert(x.length); //returns 0
x.prop = "hello";
alert(x.length); //still returns 0
</code></pre>
<p>How can I check if my map is empty?</p>

$request->$func_pointer(foreach $args write $arg);
</code></pre>
<p>My objective is to allow the API user to write functions with fixed number of parameters.
And later on pass the function name and the args which my API will execute on behalf.</p>

Understanding prototyping and augmentation

<p>I have a <a href="http://jsfiddle.net/zcWQ8/1/" rel="nofollow">fiddle</a> to help me in my understanding of JavaScript prototyping and inheritance. The comments tell the story. </p>
<pre><code>//From Douglas Crockford's "Javascript: the good parts": a helper to hide the "ugliness" of setting up a prototype
Function.prototype.method = function(name,func) {
this.prototype[name] = func;
return this;
}
function SomeFunc(value) {
this.setValue(value);
}
//Inherit the function (to me this conceptually the same as adding a member to a class)
SomeFunc.method('setValue', function (value) {
this.value = value;
return this;
});
try
{
SomeFunc(1);
}
catch(e)
{
alert(e);
}
</code></pre>
<p>Why do I get an exception? Are my notes correct in that what JavaScript calls inheritance is to a Classical programmer simply adding a new member to a class? What is the difference between augmentation and inheritance?</p>

Saving Information For The Duration The User Has A Site open

<p>Does that sound like a proper way. Anyone have samples of that? </p>
<p>Since there are multiple pages with multpile links, I wanna create something equivalient to a Session variable in javascript so I can append info to it everytime a user clicks a link and send the info only once to the db, instead of everytime a user clicks a link open a db connection and send the info.</p>
<p>The links are products so I wanna save related products, so I wanna save related product infomation. Maybe I need a cookie instead?</p>

<p>I want to unbind() whatever is allowing the columns to be resized, presumably on mouseover, but I can't figure out how to determine what callbacks the objects currently have.</p>

Python's __getattr__ in Javascript
|
<p>Is there a way to simulate Python's <code>__getattr__</code> method in Javascript?</p>
<p>I want to intercept 'gets' and 'sets' of Javascript object's properties.</p>
<p>In Python I can write the following:</p>
<pre><code>class A:
def __getattr__(self, key):
return key
a = A()
print( a.b )
</code></pre>

JavaScript enumerator?
|
<p>I want to define a list of constants that have continuous integer value, for example: </p>
<pre><code>var config.type = {"RED": 0, "BLUE" : 1, "YELLO" : 2};
</code></pre>
<p>But it's boring to add a <code>"XX" : y</code> every time I need to add a new element in it.<br>
So I'm wondering is there something like <code>enumerator</code> in C so I can just write:<br>
<code>var config.type = {"RED", "BLUE", "YELLO"}</code> and they are given unique integer value automatically.</p>

<body>
<h1 id = "slidehsowheading">Bloom Defender</h1>
</body>
</html>
</code></pre>
<p>Im trying to use this code to change the heading for a slideshow, I am kinda new to javascript so my problem is that when the alert pops up it returns as null(the alert was just for debugging), so when i try to use the null width from the h1 in this equation it is wrong. The equation is supposed to get the width of the heading after it has been changed by the timer and divid by 2 and subtract that from the width of its background divided by 2 which is 75, with this formula you can center the heading in its background element</p>

points aren't aligned with the x axis on flot chart
|
<p>I've got flot data where the points on the xaxis aren't aligned with the lines. </p>
<p>specifically, take a look at this photo:<img src="http://i.stack.imgur.com/NLKKJ.png" alt="flot chart"></p>
<p>this is the raw data that I'm using:</p>
<pre><code>[0] : [1327305600000,1989],
[1] : [1327392000000,3222.33333333333],
[2] : [1327564800000,1481.5],
[3] : [1327651200000,2061],
[4] : [1327910400000,1434],
[5] : [1327996800000,1504.75],
[6] : [1328083200000,1422.4]
</code></pre>
<p>and this is the javascript that I'm passing to flot:</p>
<pre><code>$.plot($("#something"), [datapoints], {
series: {
lines: { show: true , shadowSize:0},
points: { show: true }
},
xaxis: {
mode: "time",
timeformat: "%m/%d/%y",
reserveSpace: true
},
clickable: true,
hoverable: true,
legend: {
show: true
}
});
</code></pre>
<p>specifically, look at the second point. The timestamp for it is 1327392000000, and you can see from the following code that this should be aligned with the 1/24/2012 x-axis point, but it's not. </p>
<p><strong>var d = new Date(1327392000000);</strong>
<em>=> Tue Jan 24 00:00:00 PST 2012</em> </p>
<p>If there's any way I can workaround this, I'd love to hear it. </p>

Method inside Object undefined?

<p>On line 36 I am calling the function which is further down the page.. this works fine and references the function correctly.. but when I try to wrap that function in a setinterval setInterval('homePageFunctionality.animateCarousel($pause)', 4000); </p>
<p>It does not seem to work.. I get a homePageFunctionality is not defined..</p>
<p>Any idea why I cannot seem to reference the function when using setInterval?</p>

Managing bidirectional associations in my java model
|
<p>I have a java model where the classes have associations (1 to 1, 1 to n, n to n) that should work in both directions.</p>
<p>Example:
class A has a collection of class B</p>
<p>All instances of B must know, who their parent (A) is. If I change the parent property of B, the association needs to be updated on the other side as well.</p>
<p>I think, writing code, that keeps the associations up to date on both ends is quite tedious and errorprone.</p>
<p>So: Is there a better way of doing this? Is there a java library that can manage bidirectional associations between two objects?</p>

What does this statement mean in Java?
|
<p>Suppose there is an array declaration:</p>
<pre><code>int [] a = new int[3];
</code></pre>
<p>I'm reading a book that says the reason we need to explicitly create arrays at runtime is because we cannot know how much space to reserve for the array at compile time. So, in this case above don't we know we need to reserve 3 times the size of int of the underlying java platform ? </p>

Using multiple forms and passing information between them
|
<p>I've been messing around with Android development.</p>
<p>I made a simple form that has two fields for numbers, and when you press the Calculate button, it multiplies them. </p>
<p>What I would like to do is when I press Calculate to open another form, and pass that multiplied number to it to display it.</p>
<p>I'm really not sure how to do this though, the whole xml and findViewById thing is pretty different from what I've done before. When I started the project in Eclipse, the main.xml and strings.xml was created for me. </p>
<p>I tried googling around but I just find tutorials using one form</p>
<p>Could someone point me to a good tutorial for this, or explain how to create a new form, create/open it, and pass some information to it? </p>

List adapter display text vs. saved text
|
<p>what I have now is a listView with 3 items in it: Audience, Choosing topics, and Interviewing strategies. I want to be able to save these items as strings to open url with associated item name in the path, but the problem comes when the path has a different item name than the one I have in the listview items; we have Audience, Choosing_topics, and Interviewing as their names. How would I go about dealing away with this conflict in name without changing the names of the url or the listViewItem? Should I refer to another string array to compare the value of the first string array to to retrieve the associated item in the new array? Here's what I have as of now:</p>
<p>setListAdapter(new ArrayAdapter(this, R.layout.list_item, GREATESTHITS));
ListView lv = getListView();
lv.setTextFilterEnabled(true);</p>
<pre><code> lv.setOnItemClickListener(new OnItemClickListener() {

Add Project Reference vs Add DLL Reference
|
<p>I am newbie in .net.Today I have created a sample. In that sample, I have stored data in database using N Tier architecture. If I want to use to Use BL or DAL method in other project(I mean BL method in UI or DAL method in BL), I found two ways.</p>
<p><strong>First one is</strong> - Right click on project << Add Reference << Select Project in Project tab</p>
<p><strong>Second one is</strong> - Right click on project << Add Reference << Select DLL in Browse tab</p>
<p>Could anyone tell me that is there any difference between both of them as both works same.Is DLL way better then Project Reference.If yes, then what is the benefits?</p>
<p>Thanks in advance.</p>
<p>Regards,
Mohit Kumar. </p>

Unable to build Eclipse library projects after ADT update
|
<p>I have a main project (mainapp) I am developing for Android under Eclipse. It uses the facebook-android-sdk library (fblib) which is a separate Eclipse project with it's project properties checked as "Library". Under the project properties > android section for mainapp, I have fblib added as a library. everything works fine. </p>
<p>I needed to create a new version of mainapp which uses different database files (assets subdirectory). To do this, I created a new Eclipse project (newapp) and setup mainapp as a library under project properties > android. </p>
<p>Everything was working fine until the latest ADT update. I am getting errors trying to build/run newapp (Conversion to Dalvik format failed with error 1). If I go to mainapp and uncheck "Library" from project properties > android, I can build mainapp as a regular application and it seems to work just fine.</p>
<p>I've searched for multiple jar files in project directories, updated proguard to 4.8beta, deleted/added jars to the build path, removed exports, added exports, deleted dependencies, added "lib" directories, cleaned, restarted, rebooted and pretty much anything else google would turn up, but to no avail. </p>
<p>It was all working fine with ADT 16 so I'm really confused here. Has adding a library project to an application, which also incorporates a library project, become somehow deprecated? I just can't seem to get this working.</p>

Can I add a variable value to a passed function parameter in php?

<p>I have the following variable:</p>
<pre><code>$argument = 'blue widget';
</code></pre>
<p>Which I pass in the following function:</p>
<pre><code>widgets($argument);
</code></pre>
<p>The widgets function has two variables in it:</p>
<pre><code>$price = '5';
$demand ='low';
</code></pre>
<p>My questions is how can I do the following:</p>
<pre><code> $argument = 'blue widget'.$price.' a bunch of other text';
widgets($argument);
//now have function output argument with the $price variable inserted where I wanted.
</code></pre>
<ul>
<li>I don't want to pass $price to the function</li>
<li>price is made available once inside the function</li>
</ul>
<p>Is there any sound way I can do this or do I need to rethink my design?</p>

Tree panel error in extjs4

<p>In ExtJS4, a tree panel was created with Ext.tree.Panel. When it is clicked multiple times (around 8 to 16) to expand or collapse the tree nodes, It gives error 'event' is null or not an object at line 10708 of ext-all-debug.js. On each click it creats another node below the clicked one. This problem is seen only in IE 8 where as same code are working fine in FirFox. Can anyone fix this issue please?</p>

weird php behaviour with classes and static methods
|
<p>I maintain an application that uses a (to me) surprising PHP quirk/bug/feature. Consider this code:</p>
<pre><code><?php
class Bar {
// called statically
public function doStuff() {
print_r($this);
}
}
class Foo {
public function main() {
Bar::doStuff();
}
}
$foo = new Foo();
$foo->main();
</code></pre>
<p>Running on PHP 5.2.x, the output is: </p>
<pre><code>Foo Object ( )
</code></pre>
<p>That means, although <code>Bar::doStuff()</code> is called statically, it still has access to <code>$this</code> where <code>$this</code> is a reference to the object that called <code>Bar::doStuff()</code>. Never came across that behaviour until recently. Quite evil to rely on this in production code if you ask me.</p>
<p>If you add a <code>static</code> and change the method signature to <code>public static function doStuff()</code> it throws a <code>E_NOTICE: Undefined variable: this</code> - which seems right to me.</p>
<p>Anyone has an explanation for this behaviour?</p>

How should I be reading this code?
|
<p>So I'm trying to read this legacy code - am I reading this wrong, or is the code repeating itself multiple times? It seems like it is assigning $cuid multiple different times in multiple different ways - is it getting different values somehow? The only two ways I can see are via cookie and via GET request.</p>
<pre><code>$id = "";
$cuid = "";
session_start();
if (isset($_SESSION['id'])) {
$id = $_SESSION['id'];
$cuid = $id;
$valid_user = $_SESSION['valid_user'];
$cuname = $_SESSION['cuname'];
$website = $_SESSION['website'];
$site = $website;
$email_contact = $_SESSION['email_contact'];
}
$cuid = $_GET['cuid'];
include_once("dbfunctions.php");
if (isset($_SESSION['id'])) {
$cuid = $_SESSION['id'];
} elseif (isset($cuid)) {
$_SESSION['id'] = $cuid;
}
</code></pre>
<p>EDIT: Ok, now how would I have it use $_GET['cuid'], if $_GET['cuid'] had a value, no matter what. Basically, several sites use this, and we want a user to be able to navigate from several of them, and get a different logo each time, but if they don't navigate from other sites, to keep the same logo throughout their experience.</p>
<p>I would just check to see if $_GET['cuid'] had a value, and if it did, to do nothing else, correct, but if it did not, check for a $_SESSION['id']. Am I on the right path?</p>

Emulate Array Objects

<p>Question from Object-Oriented JavaScript book: <strong>Imagine Array() doesn't exist and the array literal notation doesn't exist either. Create a constructor called MyArray() that behaves as close to Array() as possible.</strong></p>
<p>I thought it would be a good challenge to test my skills. This is what I came up with, but it doesn't work and is very incomplete.. I am a bit stumped:</p>
<pre><code>function MyArray(){
// PRIVATE FIELDS -----------------------
var initialData = arguments;
var storage;
// PRIVATE METHODS ----------------------
function refresh(){ //this doesn't work :(
for(var i = 0; i < storage.length; i++){
this[i] = storage[i]
}
};
function initialize(){
storage = initialData;
refresh();
}
function count(){
var result = 0;
for(var item in this){
//console.log(item, parseInt(item), typeof item);
if(typeof item == 'number'){
result++;
}
}
return result;
};
initialize();
// PUBLIC FIELDS -------------------------
this.length = count();
// PUBLIC METHODS ------------------------
//todo:
this.push = function(item){
refresh();
}
this.pop = function(){}
this.join = function(){}
this.toString = function(){}
}
var c = new MyArray(32,132,11);
console.log(c, c.length);
</code></pre>

Cannot understand how add operation works on decimal numbers in javascript
|
<p>I have always been coding in java and have recently started coding in javascript (node.js to be precise). One thing that's driving me crazy is add operation on decimal numbers;</p>
<p>Consider the following code</p>
<pre><code>var a=0.1, b=0.2, c=0.3;
var op1 = (a+b)+c;
var op2 = (b+c)+a;
</code></pre>
<p>To my amazement I find out <code>op1 != op2</code> ! console.logging op1 and op2 print out the following:</p>
<pre><code>console.log(op1); 0.6000000000000001
console.log(op2); 0.6
</code></pre>
<p>This does not make sense. This looks like a bug to me because javascript simply cannot ignore rules of arithmetic. Could someone please explain why this happens?</p>

Conditionally trigger a full page postback from a link button inside an update panel
|
<p>How do I conditionally trigger a full page postback from a link button inside of an update panel?</p>
<p>I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.</p>
<p><strong>Here is the control hierarchy:</strong></p>
<pre><code>Page
Custom Control
UpdatePanel
LinkButton
</code></pre>
<p><strong>Event handler Pseudo code:</strong></p>
<pre><code>LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
</code></pre>
<p><strong>Note:</strong> I aways need the partial postback to happen. I was considering injecting a <code>__DoPostback</code> in the controls markup but this seems hacky to me.</p>
<p>Thanks for your help!</p>
