System.Diagnostics.Process.Start(...)

Its a bit more complicated but here is an example:

using System;
using System.Diagnostics;

Process p = new Process();
p.StartInfo = new ProcessStartInfo(@"Rundll32.exe shell32.dll,Control_RunDLL Sysdm.cpl, 0");
p.StartInfo.UseShellExecute = true;
p.Start();

// and optionally
p.WaitForExit();

Thanx but both the solutions gives errors. System.ComponentModel.Win32Exception: The system cannot find the file specified at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start() at TestWindowsForms.Form1.menuItem24_Click(Object sender, EventArgs e) in d:\visual studio projects\art\testwindowsforms\form1.cs:line 661 at System.Windows.Forms.MenuItem.OnClick(EventArgs e) at System.Windows.Forms.MenuItemData.Execute() at System.Windows.Forms.Command.Invoke() at System.Windows.Forms.Control.WmCommand(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Yes I've check the command " Rundll32.exe shell32.dll,Control_RunDLL Sysdm.cpl, 0 " inside the Start/Run dialog in windows 2000 and it works. But why doesn't it work when called from the program. Check with other *.cpl files as well. Any help would be Greatly appreciated !!! :((

Solution1 : async call

System.Diagnostics.Process.Start("Rundll32",
"shell32.dll,Control_RunDLL Sysdm.cpl ,0");

Solution2 : sync call

Process p = new Process();
p.StartInfo = new ProcessStartInfo("Rundll32.exe",
"shell32.dll,Control_RunDLL Sysdm.cpl , 0");
p.StartInfo.UseShellExecute = true;
p.Start();// and optionally
p.WaitForExit();
