I am trying to execute a very simple test vbs file via .Net's System.Diagnostic.Process class and see the output from the file in my .Net app. My code won't run the vbs file, producing a Win32Exception: "The specified executable is not a valid Win32 application." According to other sites I've looked at, this should be possible, so it's driving me crazy. My file has a single line: Wscript.echo "Here's a message" My code to run it is below. Does anyone have anything that can help me? private void RunScript() { Process scriptProcess = new Process(); StreamReader sr; StreamReader err; scriptProcess.StartInfo.FileName = "test.vbs"; scriptProcess.StartInfo.WorkingDirectory = "E:\\Test\\TestScripts"; scriptProcess.StartInfo.RedirectStandardError = true; scriptProcess.StartInfo.RedirectStandardOutput = true; scriptProcess.StartInfo.UseShellExecute = false; try { scriptProcess.Start(); sr = scriptProcess.StandardOutput; err = scriptProcess.StandardError; scriptProcess.WaitForExit(); richTextBox1.Text += "OUTPUT: " + sr.ReadToEnd() + Environment.NewLine; richTextBox2.Text += "ERROR: " + err.ReadToEnd() + Environment.NewLine; } catch (Exception ex) { String s = ex.Message; } } }

That's because scripts are, by definition, not executable. You have two options: - Set the FileName to cscript.exe, and the Arguments to E:\\Test\\TestScripts\\test.vbs. - scriptProcess.StartInfo.UseShellExecute = true; Since you want to read its output, you don't really get a choice. You're going with the first one.

That's solved my problem - thanks very much, Razor 2.3, you're a champion. Solution 1 lets me run the script and capture anything it writes to standard output, which is exactly what I need.
