Yeah, my bad... that's because it sends that to the shell, which in turns
kicks off iexplorer.exe - which is a different process.. you CAN do this
though:
System.Diagnostics.Process objProc = new System.Diagnostics.Process();
objProc.StartInfo.FileName = "notepad.exe";
objProc.Start();
MessageBox.Show(objProc.MainWindowTitle);
So, if you want to instantiate iexpore.exe manually, then this should work??
HTH and sorry for the confusion
