  • How to retrieve the TabHost object, if you're not using TabActivity?

    - by Lee Olayvar
    I am attempting to use a few of the simple android examples for Tab Views. One thing i am attempting to do different than all the examples i've seen so far, is to not use a TabActivity. I am trying to use a normal activity, which means i need to retrieve the TabHost object some how, so i can add tabs and etc to it. How can this be done? If you wanted to retrieve a view, you can simply use findViewById(R.id.blah), but how can you retrieve the TabHost object in a similar manner?

  • Why does FrameworkElement's FindResource() Method Accept an Object and not a String?

    - by ChrisNel52
    I understand that calling FindResource() on a FrameworkElement (e.g. a Window) can be used to find a resource in the FrameworkElement's ResourceDictionary. For example, I've used it many times to access a Style through code to add a new Setter to the Style dynamically. I always pass the x:Key value of the Style as a string into the FindResource() method. Like... Style style = w.FindResource("GridDescriptionColumn") as Style; My question is, I noticed that FindResource() accepts an argument of type object and not an argument of type string. I can't for the life of my think of a reason I would call FindResource() with an argument that is not a string. It makes me think that I may unaware of other ways to use FindResource(). Does anyone know why FindResource() accepts a parameter type of object and not string? If so, what would be an example of calling FindResource() with a parameter type other than a string? Thanks.

  • How can Java assignment be made to point to an object instead of making a copy?

    - by Matthew Piziak
    In a class, I have: private Foo bar; public Constructor(Foo bar) { this.bar = bar; } Instead of creating a copy of bar from the object provided in the parameter, is it possible to include a pointer to bar in the constructor such that changing the original bar changes the field in this object? Another way of putting it: int x = 7; int y = x; x = 9; System.out.print(y); //Prints 7. It is possible to set it up so that printing y prints 9 instead of 7?

    My current project based in Asp .net makes considerable use of Http handlers to process various requests? So, is there any way by which I can test the functionality of each of the handlers using unit test cases? We are using Nunit and Moq framework to facilitate unit testing.

  • Android - How can I access a View object instantiated in onCreate in onResume?

    - by Chris
    In my onCreate() method, I'm instantiating an ImageButton View: public void onCreate(Bundle savedInstanceState) { Log.d(AntengoApplication.LOG_TAG, "BrowsePicture onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.layout_post); final ImageButton ib = (ImageButton) findViewById(R.id.post_image); ... In onResume, I want to be able to change the properties of the ImageButton with something like: @Override protected void onResume() { super.onResume(); ib.setImageURI(selectedImageUri); } //END onResume But onResume doesn't have access to the ib ImageButton object. If this were a variable, I'd simple make it a class variable, but Android does not allow you to define View object in the class. Any suggestions on how to do this?

  • How do I return an object that is able to execute on the server?

    - by mafutrct
    Coming from a Java background, this is the way I'm thinking: The server provides an object to the client. This object should be able to execute on the server. Server: private string _S = "A"; public interface IFoo { void Bar(); } private class Foo : IFoo { void Bar() { _S = "B";} } public IFoo GetFoo() { return new Foo(); } Client: IFoo foo = serverChannel.GetFoo(); foo.Bar(); Remoting is legacy (everyone keeps pointing to WCF instead) and WCF does not support this at all basically ( http://stackoverflow.com/questions/2431510 ), so how should I implement this kind of behavior? Using 3rd party components is possible iff required. I searched on SO but found no similar question. If this has indeed been answered before, just let me know and I'll delete.

  • (iphone) Does it make difference to provide more images when the object is moving in a straight line?

    - by Eugene
    Hi. Among many animation scenarios, there are times when I want an object to move a straight line then change direction, move another straight line and so forth. Assuming I would use either UIImageView or CABasicAnimation with image arrays. Does it make difference to provide more images when the object is moving in a straight line? For example, point1 ---------point2 ------- point3 (all points are in a straight line) Providing an image at point2 to UIImageView or CABasicAnimation, gives any better animation result, assuming I don't need to change the animation speed along the course? If I were flashing each image myself, yes it would make the animation look smooth, but I'm giving the images to UIImageView/CABasicAnimation, and wonder what they do. Thank you

  • Typecasting doesn't work. How to convert an object?

    - by Nastase Ion
    Hi everyone! I need to convert a custom object to a different object. How can I do that? I know that typecasting doesn't work (the only thing is does is "shuts the compiler warnings off", but nothing more). Here is a sample code: MyType* obj1; MyOtherType* obj2; obj1 = [MyType initWithData: 1]; obj2 = (MyOtherType*) obj1; if ([obj2 isMemberOfClass: [MyOtherType class]]) { NSLog(@"OK"); } else if ([obj2 isMemberOfClass: [MyType class]]) { NSLog(@"Nope"); } The result is: Nope What can I do??

  • How to automatically trigger the App Object initialization in Powerpoint ?

    - by asksuperuser
    It is said here: http://msdn.microsoft.com/en-us/library/aa211599%28v=office.11%29.aspx Before the procedure will run, you must connect the declared object in the class module (App in this example) with the Application object. You can do this with the following code from any module. Dim X As New EventClassModule Sub InitializeApp() Set X.App = Application End Sub Run the InitializeApp procedure. Run HOW ? By hand ? I want it to automatically run when opening the powerpoint rather. Is there any way ?

  • Get a property value with only the object and the name of the property (but not the type)

    - by Vaccano
    Suppose I have a method that passes in the name of a property (as a string) and the object that the property is on (as object). How could I get the value of the property? Here is some code to make it a bit more concrete: protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight) { // The next line is made up code var currentValue = source.Current.CoolMethodToTakePropertyNameAndReturnValue(MappingName); // Paint out the retrieved value g.DrawString(currentValue.ToString() , _gridFont, new SolidBrush(Color.Black), bounds.Left + 1, bounds.Top); } MappingName is the name of the property I want to get the value for. What I need is CoolMethodToTakePropertyNameAndReturnValue. Any ideas? I am running on the Compact Framework. I would also prefer to avoid reflection (but if that is my only recourse then so be it). Thanks for any help.

  • WCF: Is there a way to return an object that is able to execute on the server?

    - by mafutrct

Or is my understanding wrong and this is not how it works in WCF? What would be a better design?

  • Why does String.Equals(Object obj) check to see if this == null?

    - by m-y
    // Determines whether two strings match. [ReliabilityContract(Consistency.WillNotCorruptState, Cer.MayFail)] public override bool Equals(Object obj) { //this is necessary to guard against reverse-pinvokes and //other callers who do not use the callvirt instruction if (this == null) throw new NullReferenceException(); String str = obj as String; if (str == null) return false; if (Object.ReferenceEquals(this, obj)) return true; return EqualsHelper(this, str); } The part I don't understand is the fact that it is checking for the current instance, this, against null. The comment is a bit confusing, so I was wondering what does that comment actually mean? Can anyone give an example of how this could break if that check was not there, and does this mean that I should also place that check in my classes?

  • Object still linked (referenced) after selecting it out of list?

    - by djerry
    Hey guys, I was wondering, and i'm not really sure, but help me out here. If you have a List items, and there's one object you need to change a property of it. Say myClass has a string property "status". I'm searching my list with a for-loop and i get my object so i do myClass item = items[i]; if i want to change the "status" property, i do this for example : item.Status = "new status"; My question/issue is this: is "item" still linked to the list item, so that if i execute the line above, it will be changed in the list as well without having to set this : items[i] = item; Hope this is clear. Thanks in advance.
