objMSHTML As New MSHTML.HTMLDocument and leaking memory. How to terminate the object and stop the leaking memory?
Please look at this comment and then look at my code below

dispose of it in Form_Terminate? How do I do that?
Code:
Module1.bas
Global AddrContent(10) As String 'an array already filled with web addresses
Form1
Option Explicit
Dim objMSHTML As New MSHTML.HTMLDocument
Dim objDocument As MSHTML.HTMLDocument
Dim BlankpgString2 As Long
Public Sub GetWebpage()
Set objDocument = objMSHTML.createDocumentFr
Do Until GG3 = 0
While objDocument.readyState <> "complete"
lblStatus.Caption = "Waiting for the document to load"
DoEvents
BlankpgString2 = Len(frmParser.txtSource.Te
Wend
set objDocument = nothing
set objMSHTML = nothing
'Even after setting the objects to nothing, it's still in memory
GG3 = GG3 - 1
Loop
End Sub

yes my mistake the set document should be inside the loop. Even setting them to nothing still makes a memory leak when changing urls
How are you determining that there is a memory leak?

I can see three threads which are not being released. You can also read about tracking down memory leaks with other tools like poolmon.exe as described in this article: http://www.winnetmag.com/Articles/Index.cfm?ArticleID=4754

Set objDocument = objMSHTML.createDocumentFr
be INSIDE the Do Until GG3 = 0 Loop?
Do Until GG3 = 0
Set objDocument = objMSHTML.createDocumentFr
While objDocument.readyState <> "complete"

As it is now, you set the MSHTML docs to nothing and keep looping. On the second pass, since you have not SET objDocument you should get an error.
Setting them to Nothing as you have is sufficient and there should be no memory leak.
