Good Afternoon,

I am trying to run a Diskpart script which will create new partitions for a Windows 7 image deployment. I have been having trouble with switching drives and running the script. I am using a cmd.exe process to run diskpart. The cmd window starts in C:\ and I need to change it to E:\, and then run the script. I have tried several items without luck. I also had it directing the output to a textbox. I provided my function below, which has some of the things i tried commented out. If someone could please help, I would greatly appreciate it.

If you need anything else, please let me know.

Private Sub CreatePartitions()
        ' If Me.InvokeRequired Then
        'Me.Invoke(New DelegateCreatePartitions(AddressOf CreatePartitions))
        Dim tmp As String
        Dim myprocess1 As New Process
        Dim StartInfo As New System.Diagnostics.ProcessStartInfo
        'StartInfo.FileName = sSystem32 & "\diskpart.exe"
        StartInfo.FileName = sSystem32 & "\cmd.exe"
        ' StartInfo.Arguments = sBootLetter & "\diskpart.exe /s createpartitions.txt"
        ' StartInfo.CreateNoWindow = True
        StartInfo.RedirectStandardInput = True
        'StartInfo.RedirectStandardOutput = True
        StartInfo.UseShellExecute = False
        myprocess1.StartInfo = StartInfo
        'Dim SR As System.IO.StreamReader = myprocess1.StandardOutput
        Dim SW As System.IO.StreamWriter = myprocess1.StandardInput
        SW.WriteLine("diskpart /s createpartitions.txt")
        'Do While myprocess1.HasExited = False
        ' tmp = SR.ReadLine & vbCrLf
        ' If tmp <> "" Then
        ' Me.txtResults.AppendText(tmp)
        ' End If
        ' Loop
        lblUpdateStatus.Text = "Partitions Created"
        ' SR.Close()
        'End If
    End Sub

The command line for running something from CMD.EXE is:
CMD /C yourCommandLine

In your case, you're missing the "/C" switch for the CMD.EXE arguments. Your command line should be this:
CMD /C E:\diskpart.exe /s createpartitions.txt

Do you happen to have the complete solution?
