Application Focus

[NvrBst]

Is there a quick way to see if my application has focus?

I've tried "this.Focused" but it doesn't return true if one of its
childen controls is what has focus (IE I just clicked a button to
check "this.Focused"). If I run the "this.myBtn.Focused" as the
button click event then I get "true". Ideally I would want something
like application.focused.

Thanks, NB

Define "focus".

I see System.Windows.Window.IsActive, available in .NET 3.0 and later.
Prior to that, I'm not sure you can do it from .NET. You may have to use
p/invoke to get at the unmanaged function.

hehe another small question if possible. How exactly do I use the
Window.IsActive object? I've added the PresentationFramework.dll
reference to my application and can see the
"System.Windows.Window.IsActiveProperty", but this isn't what I want.

Basically, how do I get my application window using the
PresentationFramework? I see
"System.Windows.Window.GetWindow(System.Windows.Wi ndow.DependancyObject)",
but what is the DependancyObject that relates to my base applications
window?

Thanks, this is probably a basic question but I can't find any
examples of google using the .NET version of Window.IsActive.

I don't know. I know basically nothing about WPF. If you're not writing
a WPF application, then Window.IsActive might not be useful to you at all,
for all I know. :(

Sorry...maybe someone else who knows more about it can offer some advice.

I simply did it the unmanaged way.

[System.Runtime.InteropServices.DllImport("user32.d ll")]
static extern IntPtr GetForegroundWindow();
public bool myAppFocused() { return GetForegroundWindow() ==
this.Handle; }
