    Exclamation can't get HWND of C# application window

    Hi guys,

    I'm creating an application switcher like the functionality of Alt-Tab, however, facing a big problem.

    Coding with C++, i use 'EnumWindows' to find the windows, but can't find those windows which are C# application.

    Seems to be a problem with WPF?

    Your doing something wrong. Outside of the exceptional, all windows can be with EnumWindows().
    *) Are you really enumerating all of them? If you enumerate using HWND_DESKTOP as the parent, only top-level windows will be found, often, windows that look like they're top-level, really aren't.
    *) What ever this window is, are sure it's actually a "window" window? For example, in I.E., input buttons and edit boxes look like genuine windows, but in fact they are not.
    I advise learning of this window using WinSpy++. If it fails to capture it, then my 2nd point is probably true.

    sorry guys, i made a filter function to filter out which windows don't have title, and accidentally the C# window that i need to find doesn't have title; that's the funny bug.

    yarin, tks for reply
