Backgroundworker problem

Hey everyone! I made a program, wich starts a console file, and run some commands in it, which takes a little time, app. 20-30 seconds, but I have the problem, that the "Succes" message is showed before the "It takes a little time.." message, so it means that the work finishes instantly, but in fact, the commands are running so far. In the "-rebuild" section it freezes 20 seconds, and than its closed, and I dont know, why it finishes instantly :( Thank you, heres my code:

Code:

---


    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        BackgroundWorker1.RunWorkerAsync()
        ProgressBar1.MarqueeAnimationSpeed = 60
        ProgressBar1.Visible = True
        exi.Enabled = False
        Button2.Enabled = False
        MessageBox.Show("It takes a little time...!")

    End Sub
    Private Sub BackgroundWorker1_DoWork(sender As Object, e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
        Dim myprocess As New Process
        Dim StartInfo As New System.Diagnostics.ProcessStartInfo
        StartInfo.FileName = "imgc.exe"
        StartInfo.RedirectStandardInput = True
        StartInfo.RedirectStandardOutput = True
        StartInfo.UseShellExecute = False
        StartInfo.CreateNoWindow = True
        myprocess.StartInfo = StartInfo
        myprocess.Start()
        Dim SW As System.IO.StreamWriter = myprocess.StandardInput
        Dim SR As System.IO.StreamReader = myprocess.StandardOutput
        SW.WriteLine("-open ""gta3.img""")
        SW.WriteLine("-import ""infernus.txd""")
        SW.WriteLine("-import ""infernus.dff""")
        SW.WriteLine("-rebuild")
        SW.WriteLine("-close")
        SW.WriteLine("-exit")
        SW.Close()
        SR.Close()
    End Sub

    Private Sub BackgroundWorker1_RunWorkerCompleted(sender As Object, e As RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted
        ProgressBar1.Visible = False
        exi.Enabled = True
        Button2.Enabled = True
        MessageBox.Show("Success!")

    End Sub

A few notes:
1. If you provide the interface containing the controls being referred to it would be easier to try the code you provided.
2. Perhaps you should use the "With" statement when referring to "StartInfo".
3. Why are you using fully qualified references such as "System.IO.StreamWriter"? If you use the "Imports" statement that shouldn't be necessary.

As to your actual question:
