HTTP multipart/form-data form data Post

Edit: I found the solution after talking a one hour break, thanks for looking here anyways! If an admin see this, you may delete this post!

I'm currently working as a QA Tester and I need to automate the web testing. It's just repetive work so I found the following code to post normal data "application/x-www-form-urlencoded" type data:

Code:

---

      Private Sub cmdSubmit_Click()
      edtPostData.Text = ""  ' Initialize an edit box for testing
      ReDim aByte(0) As Byte ' Array of bytes to hold data to post

      ' Extract the URL encoded data from the UI,
      ' and pack it into an array of bytes
      cPostData = startStr()
      PackBytes aByte(), cPostData

      ' For testing, rebuild the POST data and stuff
      ' it into an edit box
      For i = LBound(aByte) To UBound(aByte)
          edtPostData = edtPostData + Chr(aByte(i))
      Next

      Dim vPost As Variant
      vPost = aByte ' Assign the byte array to a VARIANT
      Dim vFlags As Variant
      Dim vTarget As Variant
      Dim vHeaders As Variant
      vHeaders = _
        "Content-Type: application/x-www-form-urlencoded" _
        + Chr(10) + Chr(13)

      ' You're done. Now call Navigate
      ' Note: modify path to server as appropriate
      g_oIE.Navigate "http://<server>", _
        vFlags, vTarget, vPost, vHeaders
       
     

      End Sub
            ' Utility function to pack the data to post into an array of bytes
      Private Sub PackBytes(ByteArray() As Byte, ByVal PostData As String)
      iNewBytes = Len(PostData) - 1  ' Get rid of the null termination
      If iNewBytes < 0 Then
      Exit Sub
      End If
      ReDim ByteArray(iNewBytes)
      For i = 0 To iNewBytes
      ch = Mid(PostData, i + 1, 1)
      If ch = Space(1) Then
          ch = "+"
      End If
      ByteArray(i) = Asc(ch)
      Next
    End Sub

It work fine and is about the equivilent navigating to "http://server/app?blah=fo&param=value". However more complicated forms use the following "multipart/form-data" encoding and I can't find any way to change the code to automate those. Is there a way I could change the code, or just navigate to a certain url that would have the same effect?

Here the modification I made so far but it's not working:

Code:

---

Private Sub Command1_Click()
      edtPostData.Text = ""  ' Initialize an edit box for testing
      ReDim aByte(0) As Byte ' Array of bytes to hold data to post

      ' Extract the URL encoded data from the UI,
      ' and pack it into an array of bytes
      cPostData = Text1
      PackBytes aByte(), cPostData

      ' For testing, rebuild the POST data and stuff
      ' it into an edit box
      For i = LBound(aByte) To UBound(aByte)
          edtPostData = edtPostData + Chr(aByte(i))
      Next

      Dim vPost As Variant
      vPost = aByte ' Assign the byte array to a VARIANT
      Dim vFlags As Variant
      Dim vTarget As Variant
      Dim vHeaders As Variant
      vHeaders = _
        encTypeHeader() _
        + Chr(10) + Chr(13)

      ' You're done. Now call Navigate
      ' Note: modify path to server as appropriate
      g_oIE.Navigate "http://<server>?func=ll&objAction=copy&ObjId=2112", _
        vFlags, vTarget, vPost, vHeaders
End Sub

Where Text1 holds a cut in paste of a valid Post Data String.

The code results in the web server telling me "Error parsing the GET/POST data stream.". Just a guest but is it possible that the new line character needs to be changed for another character before making the request? Or any other ideas on what I might be doing wrong?
