Internet Explorer Not always minimze

10y1kVisual Basic .NET

I'm trying to minimize internet explorer after starting. If i don't have any window before then it works fine. and if i already have instance of IE. then it doesn't minimize .

ProcessStartInfo startInfo = new ProcessStartInfo("IExplore.exe");

startInfo.WindowStyle = ProcessWindowStyle.Minimized;

string sub;

startInfo.Arguments = "www.google.com";

Process.Start(startInfo);

Actually the problem is that if I already have IE instance then newly created instance have no window handler.
It is the child instance of the already opened IE instance.It has no hWnd. So my problem is that If i don't have child instance's hwndhow do i can close that one.

you can use Windows API, ShowWindow or ShowWindowAsync function
[DllImport("user32.dll")]
public static extern int ShowWindow(int hwnd, int ncmd);
public static void MinimizeWindow(Process process)
{
try
   {
      ShowWindow(process.MainWindowHandle.ToInt32(), 2);
   }
   catch (Exception e)
   {
      //log exception
   }
}
