i'm trying to set up an application capable of running VBScript files from .NET (See here), and have most of it set up fine, but I want to test this out, so I need to be able to return data from my VBScripts. I've found that I can use WScript.Quit([ErrorCode]) to get back an integer value, but what about returning strings? Is it possible to feed them out to the DataReceivedEventHandler? Or do I need to look at a different method? Thanks.

You can write to the standard output (which will redirect it to the event handler). I believe in VBScript this is WScript.Stdout.
If you have multiple lines written out you may consider using something like a StringWriter to capture them all, ie
var p = new Process()
{
StartInfo = new ProcessStartInfo("netstat")
{
RedirectStandardOutput = true,
RedirectStandardError = true,
UseShellExecute = false,
}
};
var outputWriter = new StringWriter();
p.OutputDataReceived += (sender, args) => outputWriter.WriteLine(args.Data);
var errorWriter = new StringWriter();
p.ErrorDataReceived += (sender, args) => errorWriter.WriteLine(args.Data);
p.Start();
p.BeginOutputReadLine();
p.BeginErrorReadLine();
p.WaitForExit();
if (p.ExitCode == 0)
{
Console.WriteLine(outputWriter.GetStringBuilder().ToString());
}
else
{
Console.WriteLine("Process failed with error code {0}\nMessage Was:\n{1}", p.ExitCode
, errorWriter.GetStringBuilder().ToString());
}
