Shell

[brianh]

Hello,

In VB you had the shell function that would allow you to run command line apps with args (from your app). In C#, I have not been able to find this. I did find an article on MSDN that demonstrated how to shell a DOS app with command line args. Here is my modified code:

public class LaunchEXE
	{
		internal static string Run(string exeName, string argsLine, int timeoutSeconds)
		{
			StreamReader outputStream = StreamReader.Null;
			string output = "";
			bool success = false;
			try
			{
				Process newProcess = new Process();
				newProcess.StartInfo.FileName = exeName;
				newProcess.StartInfo.Arguments = argsLine;
				newProcess.StartInfo.UseShellExecute = false;
				newProcess.StartInfo.CreateNoWindow = true;
				newProcess.StartInfo.RedirectStandardOutput = true;
				newProcess.Start();
				if (0 == timeoutSeconds)
				{
					outputStream = newProcess.StandardOutput;
					output = outputStream.ReadToEnd();
					newProcess.WaitForExit();
				}
				else
				{
					success = newProcess.WaitForExit(timeoutSeconds * 1000);
				}
				if (success)
					{
						outputStream = newProcess.StandardOutput;
						output = outputStream.ReadToEnd();
					}
					else
					{
						output = "Timed out at " + timeoutSeconds + " seconds waiting for " + exeName + " to exit.";
					}
				}
				
			catch(Exception e)
			{
				throw (new Exception("An error occurred running " + exeName + ".",e));
			}
			finally
			{
				outputStream.Close();
			}
			return "\t" + output;
		}
			
	}

And here is where I am calling the class:

				string output;
				output = LaunchEXE.Run("PowerOff.exe", "wol -ip XXX.XXX.XXX.XXX -subnet XXX.XXX.XXX.XXX -mac xxxxxxxxxxxx", 10);
				Console.WriteLine (output);

The problem is that the app does not run correctly. It should send a wake on lan packet to the specified computer. I tested it using the command line and it works fine, but nothing happens through this app...any thought...?

Nevermind - I figured it out (syntax error in the args) - stupid me. Thanks.
