Question

I have a problem with a program that loses focus. It’s not my program. How can I write a second program to set focus to that window every 1-2 seconds? Is is possible to do that?

Answer 1

You can use following Win32 API call if you want to focus some other program/process.

[DllImport("user32.dll")]
static extern bool SetForegroundWindow (IntPtr hWnd);

private void BringToFront(Process pTemp)
{
    SetForegroundWindow(pTemp.MainWindowHandle);
}
