Bring to front inactive window
-1
I've got two WPF applications. Both of them has a window with Topmost property set to true. Window of first application is a full-screen window and second app takes only part of the screen. The important thing is also that, the second application can't be activated (activation was blocked by following code):
private const int GWL_EXSTYLE = -20;
private const int WS_EX_NOACTIVATE = 0x08000000;
[DllImport("user32.dll")]
public static extern IntPtr SetWindowLong(IntPtr hWnd, int nIndex,int dwNewLong);
[DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hWnd,int nIndex);
protected override void OnSourceInitialized(EventArgs e)
{
WindowInteropHelper helper = new WindowInteropHelper(window);
SetWindowLong(helper.Handle, GWL_EXSTYLE, GetWindowLong(helper.Handle, GWL_EXSTYLE) | WS_EX_NOACTIVATE);
}
I'm trying to bring to front second application, when user click on button which is placed on first application. I tried to achieve this by using SetForegroundWindow and ShowWindow, but it's not working. Do someone have any solution for this problem?

Thanks for answer, unfortunately I forgot to tell you about one important thing - I'm opening second window is not in the same application, I'm running it viaProcess.Start(), so I can't do it this way. Updated my question.

Then you you maybe call the second application with commandline arguments are use those to call the above methods?

It's still not working, because Activation of window is blocked.

Just to be clear: when I start second application, it's beign opened on top of screen, everything is fine. After that, when i click on first app, the second is going under it. I'm trying to reactivate it (send again to top) as I said before, but nothing is working. As a workaround for now I'm just closing second app and turning it on again when i need to reactivate it.
