I am using the below code and able to load the exe but window is minimized

string exeName = AppDomain.CurrentDomain.BaseDirectory + "electronjs\SnapELMOS.exe";
var procInfo = new System.Diagnostics.ProcessStartInfo(exeName);
procInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(exeName);
procInfo.WindowStyle = ProcessWindowStyle.Maximized;
_childp = Process.Start(procInfo);
System.Windows.Forms.Panel _pnlSched = new System.Windows.Forms.Panel();
WindowsFormsHost windowsFormsHost1 = new WindowsFormsHost();
windowsFormsHost1.Child = _pnlSched;
electrongrid.Children.Add(windowsFormsHost1);
while (_childp.MainWindowHandle == IntPtr.Zero)
{
Thread.Yield();
}
_appWin = _childp.MainWindowHandle;
SetParent(_appWin, _pnlSched.Handle);
// dispatcherTimer.Stop();

could please help me what can i do for maximized window

Hi,@Nandini Nammi . So far I tested ProcessWindowStyle.Maximized not working. I'm still looking for why and how. I'll be back when I know.

Hi,@Nandini Nammi . After my research and testing, using Process.StartInfo.WindowStyle = ProcessWindowStyle.Maximized; alone(code above dividing line ) works fine. Using in WindowsFormsHost doesn't work.Maybe there is a conflict between them, no official instructions have been found so far. Maybe someone more professional will solve your question. Or you can also ask questions in the Developer Community.

  string path = @"C:\...\WinFormsApp1.exe";  
  
      Process _childp = new Process();  
      _childp.StartInfo.FileName =path;  
      _childp.StartInfo.Arguments = "";  
  
      _childp.StartInfo.UseShellExecute = true;  
  
      _childp.StartInfo.RedirectStandardOutput = false;  
  
      _childp.StartInfo.WindowStyle = ProcessWindowStyle.Maximized;  
      _childp.Start();  
----------------------------------------------------------------  
      System.Windows.Forms.Panel _pnlSched = new System.Windows.Forms.Panel();  
        
      host1.Child = _pnlSched;  
      while (_childp.MainWindowHandle == IntPtr.Zero)  
      {  
        Thread.Yield();  
      }  
      _appWin = _childp.MainWindowHandle;  
      SetParent(_appWin, _pnlSched.Handle);
