This code will help you, in the command prompt calls as batch file non-enumerated commands: Use the System.Diagnostics namespace; Code: public static bool InvokePrompt(string Command) { try { Process InvokePrompt = new Process(); InvokePrompt.StartInfo.FileName = Environment.GetEnvironmentVariable("COMSPEC"); InvokePrompt.StartInfo.Arguments = "/Q /K /C " + Command; InvokePrompt.StartInfo.UseShellExecute = false; InvokePrompt.StartInfo.RedirectStandardOutput = false; InvokePrompt.StartInfo.CreateNoWindow = true; InvokePrompt.Start(); InvokePrompt.WaitForExit(); InvokePrompt.Close(); return true; } catch { return false; } } For run any process silently: Code: public static bool InvokeProcess(string ProcessName, string Command) { try { Process InvokeProcess = new Process(); InvokeProcess.StartInfo.FileName = ProcessName; InvokeProcess.StartInfo.Arguments = Command; InvokeProcess.StartInfo.UseShellExecute = false; InvokeProcess.StartInfo.RedirectStandardOutput = false; InvokeProcess.StartInfo.CreateNoWindow = true; InvokeProcess.Start(); InvokeProcess.WaitForExit(); InvokeProcess.Close(); return true; } catch { return false; } } Examples: Code: InvokePrompt("MD C:\\MyFolder"); InvokeProcess("C:\\Windows\\explorer.exe", ""); The functions can return true for success, and false for error, the second way can run natively cmd process, as regedit.exe, or gpedit.msc... Good luck.
