  • Transparent textbox when textbox GotFocussed Windows Phone 8.1?

    - by user3701923
    I need to have transparent textbox, in my WindowsPhone 8.1 Runtime application. I made Background="Transparent" to the textbox, so it is transparent when it is loaded. But on focus, background color changed to white. I write the following code, to make it transparent. But it doesn't run.! <TextBox Background="Transparent" GotFocus="titleBox_GotFocus" /> C# private void titleBox_GotFocus(object sender, RoutedEventArgs e) { titleBox.Background = new SolidColorBrush(Colors.Transparent); }

    I have a custom struct : struct A { public int y; } a custom class with empty constuctor: class B { public A a; public B() { } } and here is the main: static void Main(string[] args) { B b = new B(); b.a.y = 5;//No runtime errors! Console.WriteLine(b.a.y); } When I run the above program, it does not give me any errors, although I did not initialize struct A in class B constructor..'a=new A();'

  • C# equivalent of typeof for fields

    - by rwallace
    With reflection, you can look up a class from a string at run time, but you can also say typeof(Foo) and get compile time type checking, auto completion etc. If what you want is a field not a class, you can look it up from a string at runtime, but if you want compile time type checking etc., is there anyway to say something like fieldof(Foo.Bar)? I know the name of both the class and the field in advance, and I want to be able to refer to the field at compile time rather than with a run-time string lookup.

  • Usercontrol and Border Style

    - by Ram
    Hi, I have created a user control ( custom data grid view control). I have used the code specified at MSDN [site][1] [1]: http://support.microsoft.com/kb/316574 to set the border style . I am able to see the selected border style in designer. Like None, FixedSingle or Fixed3D. But when I set the border style to FixedSingle, the border does not appear at runtime. Do I need to draw it manually in the OnPaint method?

  • Compile aspx page "on the fly"

    - by user1122321
    I am trying to build an aspx page at runtime (by another aspx page which finally redirects to the new one). As far as I understand, aspx pages MUST be precompiled before a user can view them. In other words, the aspx page must be compiled to the DLL in the /bin folder. Is there a away to tell IIS, or to order it by VB.NET code, to compile a page before I am redirecting my user to the page? Any help would be greatly appriciated.

  • Use a different *.config file, depending on IIS application pool .NET version

    - by LeeCambl
    I'm looking or a way to programmatically determine which version of the .NET Framework an application pool is using in IIS, at runtime, and for a website application to then use that information to choose which *.config file it should use. Is it possible? I'm not sure where to begin. Quite a broad question, and I'm open to any method of solving the problem, so fire away! Thanks in advance, you lovely Stack Overflowers!

  • How to define an aspectj pointcut that picks out all constructors of a class that has a specific annotation?

    - by PineForest
    Here is the annotation: @Target(value = ElementType.TYPE) @Retention(value = RetentionPolicy.RUNTIME) @Inherited public @interface MyAnnotation { String name(); } Here is one annotated class: @MyAnnotation(name="foo") public class ClassA { public ClassA() { // Do something } } Here is a second annotated class: @MyAnnotation(name="bar") public class ClassB { public ClassB(String aString) { // Do something } } I am looking for an aspectj pointcut that correctly matches the constructors for ClassA and ClassB while not matching any other constructor for any other class NOT annotated by MyAnnotation.

  • Use user control in the same folder as the page.

    - by Alex
    I get this message at runtime of ASP.NET 2 page : The page 'MyFolder/blabla.aspx' cannot use the user control 'MyFolder/MyControl.ascx', because it is registered in web.config and lives in the same directory as the page. Of course I can separate them to 2 different folders and thus solve the problem, but the question is : WTF !?!?! Why I can't put them in the same folder ?! Why can't they all .. get along !?! :) Thanks

  • Port AS3/Flex app to iPhone

    - by John
    I believe Adobe tools like CS5 have ways to output as an iPhone app, but what about a regular AS3 or Flex project? Are there any tools to auto-port, or AS3/Flex iPhone implementations out there? Out of interest, how does the CS5 thing work? Is it a totally different code-path or something less drastic? For instance Flash supports Shapes and Timelines, etc... do they in fact provide an iPhone Flash runtime of some sort?

  • Haskell mutability in compiled state?

    - by pile of junk
    I do not know much about Haskell, but from what I have read about the mutability of computations (e.g: functions returning functions, complex monads and functions, etc.) it seems like you can do a lot of meta-programming, even at runtime. How can Haskell, if everything like functions and monads are so complex, compile to machine code and retain all this?

  • What to do if one library is not multi-threaded ?

    - by LB
    Hi, I would like to multi-thread an application, however one library i'm using is not multi-thread capable (i don't know what's the right word ? synchronized ?). What are my options ? As far as i know there's nothing in between threads and processes (Runtime.exec) in java (no abstraction in the jvm to have something like an isolated "java process"). How would you deal with that ?

  • What makes C faster than Python?

    - by Chris
    I know this is probably a very obvious answer and that I'm exposing myself to less-than-helpful snarky comments, but I don't know the answer so here goes. If Python compiles to bytecode at runtime, is it just that initial compiling step that takes longer? If that's the case wouldn't that just be a small upfront cost in the code (ie if the code is running over a long period of time, do the differences between C and python diminish?)

    in order to dynamically create a form, i have to find the property types of a model's properties at runtime. appengine docs says that Model.properties() will return a dictionary of properties name and their class type. when i use this method in my code, only the name is returned and the classtype value is always empty.
