C#: How to detect arguments typed into console application?
|
<p>How would I go upon detecting input for a console application in C#?</p>
<p>Let's say for example I want the console application to start up by writing:
Welcome To Food Hut
(cursor to type stuff here after the first line)</p>
<p>I would want the console application to detect two commands:</p>
<p>1: /help - which will display some help gibberish.</p>
<p>2: /food pizza -t pepperoni -d pepsi - which will display "So you would like a Pizza with Pepperoni and Pepsi to drink?"</p>
<p>How would I go upon detecting first what /command was typed and also reading the arguments like -t pepperoni (topping) and -d pepsi (to drink) if /food pizza was typed?</p>
<p>My main problem is figuring out how to detect the first word ever typed, figuring out that if it was /help then call some method that would post some help text into the console or if the command is /food then to read what is after the /food command, -t, and -p.</p>
<pre><code> static void Main(string[] args)
{
Console.WriteLine("Welcome To Food Hut");
Console.ReadLine();
// if readline equals to /help then display some help text.
// if /food command is typed, read first argument after /food Pizza, -t TheTopping
// and -p ForWhatToDrink
// and then display, 'So you would like a Pizza with Pepperoni and Pepsi to drink?'
}

setBackgroundDrawable on multiple items not working properly
|
<p>I have a gallery which has 7 + linear layouts in each view, and I set the background drawable for 7 of these layouts dynamically, depending on data I pull from out db, the position of the gallery, etc. </p>
<p>I have a for loop that launches 7 threads to fetch data and fetch the information needed for the drawables to be generated, all of which returns via a common handler, which in turn fetches each of the linear layouts and runs setBackgroundDrawable() on each of them.</p>
<p>The problem I'm running into is that I can see my constructors for the drawable being run 7 times, but draw() is only called on 1 or 2 of them. If I scroll right or left, the same thing happens with the new view. However, if I scroll back to the already drawn screen, all 7 of the linear layouts have their backgrounds drawn properly.</p>
<p>I've tried calling invalidate() and requestLayout() on the linear layouts, their parents, the gallery, but to no avail.</p>
<p>I would post my code but there is a whole mass of it, and I'm crossing my fingers that my explanation provides enough background. I appreciate any help</p>

jQuery function in .attr is called only once for all matching tags
|
<p>I'm teaching myself jQuery by writing the game of memory (where you turn tiles over two at a time, looking for matches).</p>
<p>I have 16 img tags, each representing one of the tile faces. I have an array of 16 jpg file names. I want to set the src attribute of each img tag to a random selection from my array. To do so, I wrote a function that extracts a string from the array, removes the string from the array, and returns the string. I then use this function in the onReady handler this way:</p>
<pre><code>$('.picture').attr( {src : extractArrayValue(cousinPictures)});
</code></pre>
<p>This seems to work, except that it appears that the function extractArrayValue appears to be called only once across all 16 tags. All 16 img tags get the same image, but if I refresh the page they get a <em>different</em> same 16 image files.</p>
<p>Am I correct about what's happening? And, if so, is there a straightforward way to force extractArrayValue to get called for each attribute that gets set?</p>

Javascript Combining Variables inside an Object
|
<p>Okay this seems really simple but I just can't get it to work. I need to combine variables in an obect. Something like this:</p>
<pre><code>var i = {
a: 1,
b: " sheep",
c: this.a + this.b
}
</code></pre>
<p>So that later on I can do something like:</p>
<pre><code>i.a = 3;
console.log(i.c);
</code></pre>
<p>and get "3 sheep".</p>
<p>Is this just silly? Or what is the closest thing to it?</p>

Is there a pointer-to-member equivalent in Java?
|
<p>I have a class which holds some colors for a GUI, which the program can change to its liking. For a specific element of the GUI, I'd like to be able to specify a color which is a member of that class. In C++, I could use something like</p>
<pre><code>int Pallete::*color = &Pallete::highlight;
Pallete pallete; // made in or passed to the constructor
// ...
void draw() {
drawing.color(pallete.*color);
// ...
}
</code></pre>
<p>Is there an equivalent in java? I've thought about using <code>getField(String)</code> in the Class class, or keeping the colors in a Map with string keys, but neither of these seem like very good solutions, because they rely on strings, and the compiler can't enforce that they are actually members of Pallete. I could also put all of the color names in an enum, and have some getter function which returns the associated color, but that seems like more work for me.</p>

Where is c++ size_t defined in linux
|
<p>Now I'm talking about new type definition by a programmer using typedef keyword. As long as my pupils are used to the type size_t (for example by using funciton length ()), for which I had to ask them a little effort to just "believe" it is an integer type, I think it woud be great to show noew them where this type is defined.</p>
<p>So, I've done a lot grep's in /usr/include in an ubuntu box, and what I see is that size_t is, in turn, a redefinition of size_type wich in turn is a redefinition of metadata_type, and that's the end in this directory. Not found the final "typedef unsigned int metadata_type;".</p>
<p>In /usr/src I've found anohter previous type called yy_size_t,...</p>
<p>But, in any case I've been unable the get to the end of the chain.</p>
<p>Does anyone know where to find out the final definition to check out that it is an unsigned int (or the like)?
May be I miss a development package in my box? In this case, why I'm able to compile programs using size_t type?</p>

Javascript crop function without displaying image
|
<p>First of all, I'm very new to javascript. I'm trying to develop a javascript function which takes an image and returns a cropped version of that image. By looking around on google I've found that I probably need to use a canvas in some way to accomplish this task. But does that mean I have to display the image on my page? </p>
<p>I've also looked at different javascript image processing libraries for a similar function, for example Pixastic's Crop, but I have no idea how to use it to solve my particular problem. So now I'm turning to you guys for help. Please guide me in the right direction!</p>
<p>Thanks!</p>

Where to find the Contact View in Android?
|
<p>I notice that some of the base applications in Android are using this little control (View in Android terms I guess) that shows the contact picture. When you click on the picture it shows all the ways of contacting the person (phone, sms, talk, facebook). I see this little View used in the contact app, sms app, twitter for android, facebook for android etc.</p>
<p>Is there a library or a way of getting this working on my own application or do I need to write this from scratch?</p>

Android App --> Displaying Local News
|
<p>I'm developing an android app and am not sure if something like this exists or how to even approach it. I would appreciate any advice.</p>
<p>In this app I would like to have a screen that displays only local news for a certain zip code. I would of course type in the zip code but after I do this once it would take it from there.</p>
<p>What is the best way to do this?</p>
<p>I've read a bit about RSS feeds. Is this the way to go? Is there a particular RSS feel that will let me type in a zip code...and if so, how do I display this content inside a page of my app?</p>
<p>Maybe there is a website that specifically does this for android apps and I just need to set a url to this web page to consume the information?</p>
<p>Sorry if I'm not very informed about this. This is my first app and I would really appreciate knowing how best to approach this problem.</p>
<p>Thanks</p>

In Java, create a generic parsed string cache (multiple resulting types)
|
<p>I'm trying to create a generic parsed string cache to prevent rebuilding the same object over and over. Essentially, what I'm building is something like the following:</p>
<pre><code>public class ParsedStringCache {
// static Map<Pair<String, Parser<T>>, T> _cache
// = new HashMap<Pair<String, Parser<T>>, T>();
public interface StringParser<T> {
public T parseString(String stringToParse);
}
public static <T> T getParsedObject(String stringToParse, Parser<T> parser) {
return parser.parseString(stringToParse);
}
}
</code></pre>
<p>This works fine until I try to actually cache the results, such as by using something similar to the commented out hashmap in the code above, which would essentially memoize the result of getParsedObject. Is there a reasonably simple way to do this that avoids casting?</p>

C++ --- Can a static member variable call non-static member functions

<p>I saw the following code:<br>
<a href="http://sourcemaking.com/design_patterns/singleton/cpp/1" rel="nofollow">http://sourcemaking.com/design_patterns/singleton/cpp/1</a></p>
<pre><code>class GlobalClass
{
private:
int m_value;
static GlobalClass *s_instance;
GlobalClass(int v = 0)
{
m_value = v;
}
public:
int get_value()
{
return m_value;
}
void set_value(int v)
{
m_value = v;
}
static GlobalClass *instance()
{
if (!s_instance)
s_instance = new GlobalClass;
return s_instance;
}
};
GlobalClass *GlobalClass::s_instance = 0;
void foo(void)
{
GlobalClass::instance()->set_value(1); // static variable calls non-static functions
cout << "foo: global_ptr is " << GlobalClass::instance()->get_value() << '\n';
}
</code></pre>
<p>As I know (please correct me if I am wrong here),</p>
<ol>
<li><p>Static functions can only access(write/read) static member variables</p></li>
<li><p>Non-Static functions can access(write/read) static member variables</p></li>
</ol>
<p>Based on above sample, it seems that a static variable can access non-static functions.<br>
Is this correct?</p>

How can I reshape and aggregate list of tuples in Python?
|
<p>I'm a newb to Python so apologies in advance if my question looks trivial.</p>
<p>From a psycopg2 query i have a result in the form of a list of tuples looking like:</p>
<pre><code>[(1, 0), (1, 0), (1, 1), (2, 1), (2, 2), (2, 2), (2, 2)]
</code></pre>
<p>Each tuple represents id of a location where event happened and hour of the day when event took place.</p>
<p>I'd like to reshape and aggregate this list with subtotals for each hour in each location, to a form where it looks like:</p>
<pre><code>[(1, 0, 2), (1, 1, 1), (1, 2, 0), (2, 0, 0), (2, 1, 1), (2, 3, 3)]
</code></pre>
<p>Where each touple will now tell me that, for example:
in location 1, at hour 0 there were 2 events;
in location 1, at hour 1 there was 1 event;
and so on...</p>
<p>If there were 0 events at certain hour, I still would like to see it, as for example 0 events at 0 hours in location 2: (2, 0, 0)</p>
<p>How could I implement it in Python?</p>
<p>EDIT: Thanks for help!</p>

Using a (to a class) unknown function
|
<p>I have a check if a form is already open. If it't not, it will open, if it is, it will activate the form + use a SwitchTab(int i) function. Here is some code:</p>
<pre><code>public partial class Insert : Form {
public Insert() {
InitializeComponent();
}
public Insert(int tab) : this() {
SwitchTab(tab);
}
public void SwitchTab(int tab) {
tabControl1.SelectedIndex = tab;
}
}
private void OpenInsert(int tab) {
// Loop through all forms
foreach (Form f in Application.OpenForms) {
// Check if form of Insert type is found
if (f.GetType() == typeof(Insert)) {
f.Activate();
// Unknown function
f.SwitchTab(tab)
return;
}
}
// Not found, open form
Insert insert = new Insert(tab);
insert.Show();
}
</code></pre>
<p>The reason behind this is that the Insert form has multiple tabs and I want to switch tab if an other button in the menu is clicked. The problem is that where I want to call the SwitchTab() function, the compiler doesnt know that it's a Insert class, but it only passes when it is. So is there some way to forcefully let it know it's a instance of insert?</p>

How to display data in MdiChild forms received from serialport
|
<p>Sir,
I created a MDI Parent form and three Mdi Child forms. Each child form contains a button. on clicking the button a new form is displayed. Mean to say if I click all the 3 buttons in 3 child form then there will be 3 new forms displayed. Its Fine. </p>
<p>My problems are :</p>
<p>1- Each new form which is displayed on clicking the button is also shown in the taskbar. I want each new form(apart from mdi child form) to be the mdi child of the main mdi parent.</p>
<p>2- These new forms diaplay the data received from the device connected via serialport. How many serialport objects I must create? If one, then where it must be created, on the Main mdi parent form or on the individual forms(3 new forms) ? If it is on the MDI parent form then how can i access that object in the 3 newly opened forms? If it is on the newly created forms then there would be 3 serialport objects accessing the same COM port which will result an Exception stating- "COM port is not accessible".</p>
<p>PLease reply... I am recently passed out graduate and new in c#. SO please reply so that i can undrstand properly.
Thanks....</p>

Why does <body onload="fn();"> use a function call, but window.onload=fn; use a handler function?
|
<p>I've read about the technical differences such as which option waits for the appropriate elements to load, but for most cases I understand that they both serve a similar purpose. </p>
<p>I'd like to know about the rationale behind needing to call the function (say, initialize();) when using but only using the function name if writing window.onload=myFunction. (MDN calls it a handler function). Here, I'm referring to the difference being the missing parentheses.</p>
<p>Is there an advantage to either approach? A technical reason?</p>

Sort list of strings by integer suffix in python
|
<p>I have a list of strings:</p>
<pre><code>[song_1, song_3, song_15, song_16, song_4, song_8]
</code></pre>
<p>I would like to sort them by the # at the end, unfortunately since the lower numbers aren't "08" and are "8", they are treated as larger than 15 in lexicographical order.</p>
<p>I know I have to pass a key to the sort function, I saw this somewhere on this site to sort decimal numbers that are strings:</p>
<pre><code>sorted(the_list, key=lambda a:map(int,a.split('.'))
</code></pre>
<p>But that was for "1.2, 2.5, 2.3" but I don't have that case. I thought of replacing '.' with '_' but from what I understand it converts both sides to ints, which will fail since the left side of the _ is a string.</p>
<p>Any help would be appreciated</p>
<p><strong>EDIT</strong>: I forgot to mention that all the prefixes are the same (song in this example)</p>

Is there an example of how to use a TouchDelegate in Android to increase the size of a view's click target?

<p>My understanding is that when you have a view that's too small to easily touch, you're supposed to use a TouchDelegate to increase the clickable region for that view.</p>
<p>However, searching for usage examples on Google turn up multiple people asking the question, but few answers.</p>
<p>Does anyone know the proper way to set up a touch delegate for a view to, say, increase its clickable region by 4 pixels in every direction?</p>

How do I get started using Java for web development?
|
<p>OK, here's the easiest question for the day for those of you who have ever done this. I'm learning Java and I heard that Java can be used to build websites. I am coming from a PHP background, so I would really appreciate using a strongly-typed well-designed language like Java for web development. However, either I can't get my search keywords right, or there's not a single guide out there that will explain what I actually need to do to build websites in Java.</p>
<p>For PHP, I would need to install Apache and PHP, or a nice package like WAMP, and start putting php files in the web root. </p>
<p>What is Java's equivalent?</p>

How do I get an animation to play at the same time as a TextToSpeech utterance in Android
|
<p>I have a set of buttons in my ChordActivity application in a LinearLayout. When a button is clicked, I want the TextToSpeech engine to speak the name of the button clicked ( e.g; Minor 7th ), which is working fine. I also want an animation of the button 'popping out then back' to occur, which I also have working. The problem is that no matter how I arrange the code, the speech happens first, then the animation happens afterward. I want them to happen at the same time. I know that TextToSpeech has its own message queue, so I assumed that if I used a runnable to do the animation, I could get the speech and the animation to happen simultaneously, but it doesn't. I then backed out the runnable and now have the following code. Does anyone have a solution for this? Much Appreciated.</p>
<pre><code>private void speakChordMessage(View v) {
image = (ImageView) v;
image.startAnimation(animScale);
chordTTS.playSilence(2000, TextToSpeech.QUEUE_FLUSH, null);
chordTTS.speak(str1, TextToSpeech.QUEUE_FLUSH, null);
while (chordTTS.isSpeaking()) {
}

var prov_status_dict={};
....
</script>
</code></pre>
<p>Later on in a javascript method I'm using the variable normally.</p>
<pre><code>temp=prov_status_dict[current_as_id];
</code></pre>
<p>I'm having issues with it on opera and ie, while on firefox it works. This is what opera's error console reports:</p>
<pre><code>JavaScript - http://localhost:8000/input/
Event thread: click
Error:
name: ReferenceError
message: Statement on line 62: Undefined variable: prov_status_dict
stacktrace: n/a; see opera:config#UserPrefs|Exceptions Have Stacktrace
</code></pre>
<p>I've noticed that the problem is with global variables in general. I tryed moving some into hidden fields, but the same error pops up on the next use of a global var.</p>
<p>Help?</p>

<p>I've tried setting the frame of self.tableView in different places (viewDidLoad, viewWillAppear etc) but nothing happens. The tableView is created by IB and not programtically.</p>
<p>I've tried added a footer to my table view but that's not what I want, because the footer actually scrolls up, I want a static non moving View at the bottom of the screen.</p>

Python is converting double quotes to single quotes in new variable

<p>I'm trying to save a variable with double quotes in python, because I need to pass the double quoted JSON to a template and single quotes wont work with what I'm doing. So I set the variable in python to:</p>
<pre><code>json = {
"auth": {
"key": "auth-code-here"
},
"template_id": "id-here",
"redirect_url": "url-here",
}
</code></pre>
<p>But immediate in python, it's saved as </p>
<pre><code>{'redirect_url': 'url-here', 'template_id': 'id-here', 'auth': {'key': 'auth-code-here'}}
</code></pre>
<p>Is there a way I can save it as double quoted? Or will I need to process this in a django template to replace the single quotes for double quotes?</p>

Reading to hash table from file c#
|
<p>(In this windows form application) I'm trying to read data from a file into a hash table and populate text boxes with the data in the hash table but when I run the code I'm always thrown the exception "Item has already been added. Key in dictionary: '' Key being added: '' "</p>
<p>Initial code:</p>
<pre><code>string[] fileLines = File.ReadAllLines(@"C:path/ajand.txt");
foreach (string line in fileLines)
{
// to split the first 9 chars in the string and use them as key values
string[] match = Regex.Split(line, line.Substring(0,9));
hT.Add(match[0], line);
}
</code></pre>
<p>so i tried checking for key duplicates with the following code</p>
<pre><code> string[] fileLines = File.ReadAllLines(@"C:path/ajand.txt");
foreach (string line in fileLines)
{
string[] match = Regex.Split(line, line.Substring(0,9));
if(!hT.ContainsKey(match[0])) // to check duplicates
hT.Add(match[0], line);
}
</code></pre>
<p>But when I run the program the corresponding text boxes are not populated with the data that "seems" to have been added to the hash table.
Please any ideas what the problem is.</p>

Python string representation of binary data
|
<p>I'm trying to understand the way Python displays strings representing binary data.</p>
<p>Here's an example using <a href="http://docs.python.org/library/os.html#os.urandom" rel="nofollow">os.urandom</a></p>
<pre><code>In [1]: random_bytes = os.urandom(4)
In [2]: random_bytes
Out[2]: '\xfd\xa9\xbe\x87'
In [3]: random_bytes = os.urandom(4)
In [4]: random_bytes
Out[4]: '\r\x9eq\xce'
</code></pre>
<p>In the first example of <code>random_bytes</code>, after each \x there seem to be values in hexadecimal form: fd a9 be 87.</p>
<p>In the second example, however, I don't understand why <code>'\r\x9eq\xce'</code> is displayed.</p>
<p>Why does Python show me these random bytes in this particular representation? How should I interpret <code>'\r\x9eq\xce'</code>?</p>

Proper way to add functionality to handle() in a python TCP Server?

<p>I have code like this:</p>
<pre><code>class SingleTCPHandler(SocketServer.BaseRequestHandler):
""" One instance per connection. """
def handle(self):
data = Net.recv_from_socket(self.request)
GUI.run(str("RECV'd message: %s" % data))
class SimpleServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
def __init__(self, server_address, RequestHandlerClass):
SocketServer.TCPServer.__init__(self, server_address, RequestHandlerClass)
</code></pre>
<p>But I don't want to have to use <code>GUI</code>, a global variable, to contain the function that I want to call when a message is received by my server. Instead I want to send the <code>SingleTCPHandler</code> class the <code>GUI</code> object so it can call the function locally instead of referencing a global variable.</p>

Simple Sentence Reverser in C++
|
<p>I'm trying to build a program to solve a problem in a text book I bought recently and it's just driving me crazy.</p>
<p>I have to built a sentence reverser so I get the following:</p>
<p>Input = "Do or do not, there is no try."
Output = "try. no is there not, do or Do"</p>
<p>Here's what I've got so far:</p>
<pre><code>void ReverseString::reversalOperation(char str[]) {
char* buffer;
int stringReadPos, wordReadPos, writePos = 0;
// Position of the last character is length -1
stringReadPos = strlen(str) - 1;
buffer = new char[stringReadPos+1];
while (stringReadPos >= 0) {
if (str[stringReadPos] == ' ') {
wordReadPos = stringReadPos + 1;
buffer[writePos++] = str[stringReadPos--];
while (str[wordReadPos] != ' ') {
buffer[writePos] = str[wordReadPos];
writePos++;
wordReadPos++;
}
} else {
stringReadPos--;
}
}
cout << str << endl;
cout << buffer << endl;
}
</code></pre>
<p>I was sure I was on the right track but all I get for an output is the very first word ("try.") I've been staring at this code so long I can't make any headway. Initially I was checking in the inner while look for a '/0' character as well but it didn't seem to like that so I took it out.</p>

the best approach to giving an error message when validating
|
<p>I am a new programmer and am attempting to do some validation for a basic registration form. I have built a basic registration form that sends the user back to the same page when submitted. I have also created a user class and have created some basic validation functions. However, the functions have the error messages built into them. I obviously put the functions on the top of the registration form so when there is an error the errors are posted on the registration form. However, I have no control on how the error messages look and would like to know if there is a lot better way to somehow echo the error messages from outside the class so I can use some type of css or something else for better control of how they look. I hope that makes sense. Also when there is an error the user is sent back to an empty registration form. I was trying to figure out how to keep the valid information in the text boxes and just make them redo the invalid information. Here is a basic example of a validation I have done. I know its basic but I am very new to programming</p>
<pre><code>function validate_password($password)
{
$valid = TRUE;
if ($password == '')
{
echo "<p> Please enter a value for the password </p>";
$valid = FALSE;
}
elseif($_POST['pwd'] !== $_POST['pwd2'])
{
echo "The passwords do not match please try again";
$valid = FALSE;
}
return $valid;
