Running script in selected path

I currently have this piece of code:

   Sub Button1Click(sender As Object, e As EventArgs)



            If dlgFolder.ShowDialog = Windows.Forms.DialogResult.OK Then

                txtPath.Text = dlgFolder.SelectedPath


                Try

                    Dim CopyFile As String = Path.Combine(Directory.GetCurrentDirectory, "pdftk.exe")
                    Dim CopyLocation As String = Path.Combine(dlgFolder.SelectedPath, "pdftk.exe")
                    Dim pyScript As String = Path.Combine(Directory.GetCurrentDirectory, "pdfmerge.py")
                    Dim pyLocation As String = Path.Combine(dlgFolder.SelectedPath, "pdfmerge.py")

                    System.IO.File.Copy(CopyFile, CopyLocation, True)
                    System.IO.File.Copy(pyScript, pyLocation, True)

                Catch copyError As IOException
                Console.WriteLine(copyError.Message)
                End Try         
            End If
End Sub

This copies two files in the current working directory (which will be the default install folder) to the selected path from the Fodler Dialog Browser. This works correctly.

Now what I want to do is too run "pdfmerge.py" into the selected folder path. I tried the below code but the script is still running in the current working directory.

Sub BtnNowClick(sender As Object, e As EventArgs)

        Dim myProcess As Process
        Dim processFile As String = Path.Combine(dlgFolder.SelectedPath, "pdfmerge.py")

        myProcess.Start(processFile, dlgFolder.SelectedPath)



    End Sub

You can set the process's working directory.

Dim p As New ProcessStartInfo
p.FileName = Path.Combine(dlgFolder.SelectedPath, "pdfmerge.py")
p.WorkingDirectory = dlgFolder.SelectedPath
Process.Start(p)

One question: are you ensuring the dlgFolder.SelectedPath is correct? Without knowing the inner workings of your program, it appears possible to press BtnNow before Button1, meaning dlgFolder.SelectedPath won't have been set by the user.

Try using the overload of Process.Start() that takes 5 arguments.

Start ( _
fileName As String, _
arguments As String, _
userName As String, _
password As SecureString, _
domain As String _
)

You may be able to pass in null for userName and password, but if your directory is outside of the standard ones that you have permission for, you may need to put your username and password in. domain would be the working directory, I think.
