  • EditText and Button on the same line with Textiew underneath?

    - by Kevin
    Hi, I am trying to have an EditText widget next to a button with a text view underneath. The EditText should resize and fill the screen accordingly, while the button's width is always only what it needs to be by setting the width to wrap_content. The layout should not be relative. Below is the code I have so far some of which was found here on StackOverflow. Removing the text view gives the desired appearance for the EditText and button, but when the TextView is added the view goes to ... well. Not sure why the code is not showing? I put it into a < code< pre block without success. http://pastebin.com/WgH6qrTm

  • Actionscript 2 call function from variable

    - by NebNeb
    How can i call a function form a variable. var upfunction = init; //or var upfunction = init(); I have tried the above code and it does not work. I want to be able to call that variable from a keypress and change the variables function. For example. function init(){ //Do whatever } function init2(){ //Do another thing } var upfunction = init(); if (Key.getCode() == Key.UP) { upfunction; } Then later doing upfunction = init2(); That way i could change the function without having much code. Sorry if this is a noob question but all i do is copy and paste code i have found.

  • How to use TestAndSet() for solving the critical section problem?

    - by Dan Mantyla
    I'm studying for an exam and I'm having difficulty with a concept. This is the pseudo code I am given: int mutex = 0; do { while (TestAndSet(&mutex)); // critical section mutiex = 0; // remainder section } while (TRUE); My instructor says that only two of the three necessary conditions (mutual exclusion, progress, and bounded waiting) are met with this code, but I don't understand which one isn't being met...?? How should the code be modified to support the missing condition to solve the critical region problem? Thanks in advance for any insight!

  • Design pattern for data entry forms with LINQ2SQL

    - by petebob796
    I am about to start a new winforms data entry application, it already has the database designed which I am comfortable with. I was going to use LINQ2SQL to access the tables to keep things type safe but am now wondering about design patterns, something I am just getting into. Since LINQ is giving me objects to use should I still create classes in between to hold the validation code and helper methods or should these just go in with the UI? It just seems I will end up with classes sat in between with little code which will cause the UI classes to have code just getting and setting values in the intermediate class and returning from validation to flag errors... Any good reading on this? Should I consider the entity framework (or similar) instead?

  • Java static source analysis/parsing (possibly with antlr), what is a good tool to do this?

    - by Berlin Brown
    I need to perform static source analysis on Java code. Ideally, I want the system to work out of the box without much modification from me. For example, I have used Antlr in the past, but I spent a lot of time building grammar files and still didn't get what I wanted. I want to be able to parse a java file and have return the character position of say: Character position start and end of a Java block comment Character position start and end of a Java class file Character position start and end of a Java method declaration, signature, and implementation. It looks like Antlr will do that, but I have yet to finish a grammar that actually gives me the positions of the code I need. Does anyone have that complete Antlr grammar and Java code to give the character positions of the parts in the Java source.

  • Python Tkinter after loop not working fast enough

    - by user2658538
    I am making a simple metronome where it plays a tick sound every few milliseconds depending on the bpm and plays the sound using the winsound module. I use tkinter because there will be a gui component later but for now the metronome code is working, it plays the sound at a constant rate, but even though I set the after loop to play the sound every few milliseconds, it waits longer and the beat is slower than it should be. Is it a problem with the code or a problem with the way I calculate the time? Thanks. Here is my code. from Tkinter import * import winsound,time,threading root=Tk() c=Canvas(root) c.pack() class metronome(): def __init__(self,root,canvas,tempo=100): self.root=root self.root.bind("<1>",self.stop) self.c=canvas self.thread=threading.Thread(target=self.play) self.thread.daemon=True self.pause=False self.tempo=tempo/60.0 self.tempo=1.0/self.tempo self.tempo*=1000 def play(self): winsound.PlaySound("tick.wav",winsound.SND_FILENAME) self.sound=self.c.after(int(self.tempo),self.play) def stop(self,e): self.c.after_cancel(self.sound) beat=metronome(root,c,120) beat.thread.start() root.mainloop()

  • WPF UserControl event called only once?

    - by 742
    Hi Everyone, I need to bind two-way a property of a user control to a property of a containing user control. I also need to set a default value to the property from code in the child (cannot be done easily from XAML tags). If I call my code from the child constructor, the value is set in the parent but the change callback routine is not triggered (my understanding is that the parent doesn't yet exist at the time the child is created). My current workaround is to catch the Loaded event of the child and to call the code from the handler. Howver as Loaded is called more than once, I need to set a flag to set the property only the first time. I don't like this way, but I don't know if there is a single shot event that could be used, or if this can be done otherwise. Any feedback based on your experience?

  • jQuery toggle show XHTML Smarty some clahes maybe? It doesn't show..

    - by Kyle Sevenoaks
    Hi, at this page new customer, there is something that it doesn't like, my boss asked me to make a show function that shows the new customer registration when the user clicks on the "ny kunde" button. Here is an example of the code I got working (I'm a jQuery noob). I guess there is some clash between this and the functions already installed on the page, but what? #roundbigboxnykunde is meant to be hidden on the page as on the jsfiddle example, but I have shown it to let you see what else is on the page. Code on my .tpl <button id="button1">&nbsp;</button> {literal} <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(function() { //checkbox $("#button1").click(function()1 $(".newCustomer").toggle("show"); }); });? </script> {/literal} <div class="newCustomer">... Thanks.

  • Can jQuery's fadeIn work without AJAX?

    - by Thierry Lam
    I'm submitting a form, sometimes I have some messages that I want to show to the user. I want those messages to jQuery fadeIn after they click on the submit button. Is it possible to achieve that if the submission doesn't involve any AJAX? Here's a sample Django/Python code: # View code message = 'feedback to user' # Template <div id="messages">{{ message }}</div> The equivalent PHP code of the above might be: <?php $message = 'feedback to user'; ?> <div id="messages"><?= $message ?></div> I want #messages above to fade in after a POST. How can I achieve that?

  • Capturing system command output as a string

    - by dreeves
    Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

  • Is there a Windows utility that will let me do multiple programmatic find/replaces on text that I cu

    - by billmaya
    I've inherited some C# code that contains about a thousand lines of source that I need to modify, transforming it from this: newDataRow["to_dir"] = comboBox108.Text; To this: assetAttributes.Add("to_dir", comboBox108.Text); The lines occur in various places throughout the application in groups of 40 or 50. Modifying each line by hand in Visual Studio 2008 can be done but it's labor intensive and prone to errors. Is there a Windows utility out there that will let me cut and paste groups of code into it and then run some sort of reg-ex expression to transform the individual lines one-by-one? I'd also be willing to use some sort of VS 2008 add-in that performed the same set of reg-ex operations against a selection of code. Thanks in advance.

  • Xcode 3.2 not recompiling changed files

    - by Jason
    I've been programming a new iPhone application and everything has been chugging along fine, until this afternoon when I noticed that any changes I was making were not being reflected in the actual app! Even code that throws errors isn't getting picked up by the compiler. To get around this, I have taken to the following procedure: Finish making my edits, and add code to the file which will always throw a compiler error. Right-click the file I have just edited, and hit "Compile" to just compile that one file; it will throw the error. Remove the error-producing code, and again right-click and "Compile" the one file. Build the whole project This is quite annoying, and I can't figure out why this would suddenly happen to my Xcode project. Any thoughts on what could be causing this, and how to fix it?

  • Could someone explain __declspec(naked) please?

    - by Scott
    I'm looking into porting a script engine written for Windows to Linux; it's for Winamp's visualization platform AVS. I'm not sure if it's even possible at the moment. From what I can tell the code is taking the addresses of the C functions nseel_asm_atan and nseel_asm_atan_end and storing them inside a table that it can reference during code execution. I've looked at MS's documentation, but I'm unsure what __declspec(naked) really does. What is prolog and epilog code mentioned in the documentation? Is that related to Windows calling conventions? Is this portable? Know of any Linux-based examples using similar techniques? static double (*__atan)(double) = &atan; __declspec ( naked ) void nseel_asm_atan(void) { FUNC1_ENTER *__nextBlock = __atan(*parm_a); FUNC_LEAVE } __declspec ( naked ) void nseel_asm_atan_end(void) {}
