I am running the following code, but I'm getting an error that doesn't make much sense to me:

"Specified repeat count is not valid"

The following code works ok, but if I uncomment the For .... Next loop, it falls over on the line System.Windows.Forms.SendKeys.SendWait(strText)

Code:
    Private Sub btnFirstExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFirstExport.Click

        Dim strText As String = "Some Text" & vbCr

        'For x As Integer = 0 To Me.lstFirstFile.Items.Count - 1

        '    strText = strText & Me.lstFirstFile.Items(x) & vbCr

        'Next

        Dim myProcess As Process = New Process()
        myProcess.StartInfo.FileName = "Notepad"
        myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal
        myProcess.Start()

        ' wait until the program is ready for input
        myProcess.WaitForInputIdle(1000)

        If myProcess.Responding Then

            System.Windows.Forms.SendKeys.SendWait(strText)

        Else
            myProcess.Kill()
        End If

    End Sub
