Using the Process to launch a program

Hello,

I have some code that launches a process to unzip some files.

        Dim myproc As Process = New Process
        myproc.StartInfo.WorkingDirectory = Chr(34) & Folder & Chr(34)
        myproc.StartInfo.FileName = Chr(34) & rar & Chr(34)
        myproc.StartInfo.Arguments = "x -Y " & Chr(34) & Folder & "\*.zip" & Chr(34)
        myproc.Start()
        MsgBox(myproc.ExitCode)
        myproc.WaitForExit()

If I open a dos box and do the equivalent it works perfectly, but for some reason this exists with exitcode 0 and nothing happens...

Any ideas?

tnx

You should check the output and error, by getting the StandardOutput and StandardError.

Example:

Dim ErrorString As String = Process.StandardError.ReadToEnd()

Open in new window
