C/C++/C# Force window to be on top

Is the there a way to force another window to be on top? Not the application's window, but another one, already running on the system. (Windows, C/C++/C#)

BringWindowToTop() has no effect if you want to bring a applications window from behind (or minimized) to front. The following code does this trick reliably:

ShowWindow(hwnd, SW_MINIMIZE);
ShowWindow(hwnd, SW_RESTORE);

BOOL CALLBACK EnumWindowsProc(HWND hWnd, long lParam) {
     wchar_t buff[255];

    if (IsWindowVisible(hWnd)) {
        GetWindowText(hWnd, (LPWSTR) buff, 254);
        //wprintf(L"%s\n", buff);
        wstring ws = buff;
        if (ws.find(L"Firefox") != ws.npos)
        {
            ::SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
        }
    }
    return TRUE;
}

int main(){
    BOOL enumeratingWindowsSucceeded = ::EnumWindows( EnumWindowsProc, NULL );
}

SetWindowPos(that_window_handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

BringWindowToTop moves the window to the top of the Z-order (for now) but does not make it a topmost window.

You can use the Win32 API BringWindowToTop. It takes an HWND.

You could also use the Win32 API SetWindowPos which also allows you to do things like make the window a top-level window.
