Getting ouput from Process.Start() in Vista

[martho]

Hello!

I want to call a php-script out of a C#-Application and get the output of the php-script as result:

// Call PHP			
				System.Diagnostics.Process proc = new System.Diagnostics.Process();
				proc.StartInfo.FileName = sPathToPhp+"php.exe";
				proc.StartInfo.Arguments = sScript + " " + sParameter;
				proc.StartInfo.UseShellExecute = false;
				proc.StartInfo.RedirectStandardOutput = true;
				proc.StartInfo.CreateNoWindow = true;
				proc.Start();
				proc.WaitForExit();
				String sOutput = proc.StandardOutput.ReadToEnd();
				proc.Close();

This works fine in XP, but in Vista, sOutput keeps empty - any ideas what could be wrong?
