Objective: I am trying to get the url that is being loaded before it gets loaded. I am guessing that the best way to access this is the HTMLDocument object in the DownloadBegin event of IEModule.vb. When attempting the code below, I receive the errors as listed beneath.
Can you help me in figuring out why I cannot access the HTMLDocument in this fashion? I have tried assigning it to a mshtml.HTMLDocument object, using Me.HTMLDocument, etc. but nothing seems to work. Note: Getting the url seems to work after the error is experienced.
What is the "official" way to open and access this Me.HTMLDocument object within AddInExpress code?
Thanks in advance!
VB Code:
Private Sub IEModule_DownloadBegin() Handles Me.DownloadBegin
MsgBox("in IEModule_DownloadBegin")
If Not (HTMLDocument Is Nothing) Then
'Dim currentDomain As String = HTMLDocument.domain
End If
End Sub
VB Local Variable:
- HTMLDocument {"Exception has been thrown by the target of an invocation."} mshtml.HTMLDocument
TargetInvocationException Error at this line 3:
Public ReadOnly Property HTMLDocument() As mshtml.HTMLDocument
Get
Return CType(Me.HTMLDocumentObj, mshtml.HTMLDocument)
End Get
End Property

Hello Alexander,

I would recommend using the DocumentComplete event instead of the DownloadBegin one. In the last event handler you will not get alive HTMLDocument. |

Eugene:
thanks so much for the prompt reply.
For performance reasons, I would like to conduct this transaction prior to the page loading.
Is there any other way to get the URL being loaded, preferably before the page is loaded? |

Hello Alexander,

Yes, there is one. You can use the BeforeNavigate2 event of the add-on module. |
