foreach (ProductConfiguration obj in lstProductConfig)

{

//I want to add some code to display some window form here before runing the  process and not freez the main win form

ProcessStartInfo PSI = new ProcessStartInfo(obj.ExePath);

PSI.WindowStyle = ProcessWindowStyle.Hidden;

PSI.CreateNoWindow = false;

PSI.UseShellExecute = false;

PSI.RedirectStandardOutput = true;

PSI.CreateNoWindow = true;

System.Diagnostics.Process p = System.Diagnostics.Process.Start(PSI);

p.WaitForExit();

}
please if any body get what I mean and can help me in doing that please send me or tell me about some url may help me in doing that

I have done an app like this in vb net. I created several process and every process got it's own window as a child from the desktop. In that window, I displayed specific process information. What it did and how the process evolved.

It worked great, but in VB net.
To make the thread that run the form dependent on the process and not the main form I used delegates. I think you must do the same in C#. Put the creation of the process and it's window into a seperated class. And when you enumerate all your objects, create for each obj such a class, passing the obj parameters through the new methode.
It can be quite tricky. But I am sure you will succeed.

Good luck
