How can I capture output from an arbitrary console application from within my Window Form application

Use the Process class found in the System.Diagnostic namespace.

	Process proc = new Process();
	
	// test.exe is a console application generated by VC6
	proc.StartInfo.FileName = @'C:\test\test.exe';

	proc.StartInfo.Arguments = '';
	proc.StartInfo.CreateNoWindow = true;
	proc.StartInfo.UseShellExecute = false;
	proc.StartInfo.RedirectStandardOutput = true;

	proc.Start();
	string output = proc.StandardOutput.ReadToEnd();

	//output now holds what text.exe would have displayed to the console
