Getting data from webpage using WebBrowser

I'm trying to get data from a webpage into my VB app.  The department I'm in submits all of their defects in TeamTrack (this is the website).  We also need to list all these defects in some sort of defect log (my vb app).  I would like to catch all the info I need for the defect log when they submit the defect in teamtrack.  I messed around with another intranet site we use and I was able to get values from the site by using the document property of WebBrowser control - code: Text1.Text = WebBrowser1.Document.Forms("frm").lastname.Value  I'm having trouble with the TeamTrack website, and I think, but I'm not sure, it's because the TeamTrack website is in frames.  Any ideas on how I can do this?


I'm in the process of researching as I'm not sure of the best way to go about doing this. I came across the WebBrowser control so I'm trying to accomplish what I need to do with it.  If anyone has a simpliar or more efficient solution, please let me know.

Sorry this is so long.  Any help would be greatly appreciated.  Thank you in advance.

document object has a Frames property collection, you could use it to navigate each frame and get data as usually do (each frame is a document object itself)

Thanks Richie.  Could you provide an example (some code) if it's not too much trouble?  I would appreciate it.  

Thanks,
Sam

Option Explicit

Dim WithEvents ie As InternetExplorer
Sub test()
Set ie = New InternetExplorer
With ie
    .navigate "C:\A_project\frames_main.htm"
    .Visible = True
End With
End Sub


Private Sub ie_DocumentComplete(ByVal pDisp As Object, URL As Variant)
If (pDisp Is ie) Then
    Dim iedoc As HTMLDocument, f As Integer
   
    For f = 0 To ie.document.frames.Length - 1
        Set iedoc = ie.document
       
        Debug.Print iedoc.frames.Item(f).document.body.innerText
        Debug.Print "***************************************"
    Next f
End If
End Sub

Richie,
I'm testing the code you listed above and I keep getting the error message 'Class does not support Automation or does not support expected interface'.  The error is occuring at the line 'Set ie = New InternetExplorer'.  Any suggestions?  I'm really struggling with this.  Again, I appreciate you help.  Thanks again.

That code doesn't uses Webbrowser control but Internet explorer itself (the approach is the same).
i tested it and it works.

I've awarded the points to Richie for his help.  I'm sure his code works, but I've been pulled from the project and I'm unsure when I'll be working on it again.  I hope Richie (or someone) will be able to help when/if I begin to work on this problem again.  Thanks.
