window doesn't gain focus after summon

[Eyal Wiener]

When summoning the command window, sometimes the window appears, top most, but doesn't gain focus.
This is critical, cause this happens many times, and when the window ain't got no focus, it doesn't capture keystrokes.

You can invoke this behavior by working on some app, calling MB to appear, and then, while the command window is open, click outside of it, back on the app. and from this moment forward, mighty box doesn't get *keyboard focus* when called while using this app. as if it had a higher precedence over it

I used Win32API to resolve this

[DllImport("User32.dll")]
public static extern Int32 SetForegroundWindow(IntPtr hWnd);

[DllImport("user32")]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);

IntPtr hWnd = new WindowInteropHelper(MBMain.cmdWin).Handle;

uint TOPMOST_FLAGS = SWP_SHOWWINDOW | SWP_NOMOVE | SWP_NOSIZE | SWP_ASYNCWINDOWPOS;
bool success = SetWindowPos(hWnd, HWND_TOP, 0, 0, 0, 0, TOPMOST_FLAGS);

// Very very nasty hack:
while (SetForegroundWindow(hWnd) == 0) // on failure, try again
 Console.Write("#");
Console.WriteLine("@");
