Webbrowser control with internet transfer control

Hi,
If I use the internet transfer control to download a webpage, then use the open, write and close methods to insert the html into a webbrowser control, is there a way to also insert the cookies so that when links are clicked on in the webbrowser control the cookies will carry through?

I'm trying to find a way to use the webbrowser control to turn off images for a particular instance of the webbrowser control only and only for certain pages.  I thought this might be a way that I could accomplish it.

Here's another thread that uses a different route to solve the problem.  This method would be using the internet transfer control if it's possible.

The link below is the other, what I believe to be more difficult method.

Please note that changing the registry item for not downloading images isn't possible since my program will be running while browsers are running and we can't have all browsers not downloading images.  Only the webbrowser instance for the webbrowser control.

If the Inet control returns any cookies, you can parse them and set them through the WebBrowser as shown below.

Private Sub Command1_Click()
    'Get the current cookies...
    Call MsgBox(WebBrowser1.Document.cookie)
    'Add a cookie...
    WebBrowser1.Document.cookie = "name=1"
    'Get the new cookies to see our addition...
    Call MsgBox(WebBrowser1.Document.cookie)
    'Change the cookie we just added...
    WebBrowser1.Document.cookie = "name=2"
    'Get the new cookies to see our modification...
    Call MsgBox(WebBrowser1.Document.cookie)
End Sub
Private Sub Form_Load()
    WebBrowser1.Navigate "http://www.google.com"
End Sub

There may be an issue with that, however. Since you're writing out the html for certain sites without being at the actual domain, I don't believe the cookie(s) you use will belong to that domain so IE may not send them (I'm not sure though). You can alternatively send the cookies for each link the person goes to as shown below.

Private Sub Form_Load()
    WebBrowser1.Navigate "http://www.google.com"
End Sub
Private Sub WebBrowser1_BeforeNavigate2(ByVal pDisp As Object, URL As Variant, Flags As Variant, TargetFrameName As Variant, PostData As Variant, Headers As Variant, Cancel As Boolean)
    'if no headers were sent.. cancel and send our headers (cookie(s))
    If Headers = vbNullString Then
        Cancel = True
        WebBrowser1.Navigate "www.yahoo.com", , , , "your cookie(s) here"
    End If
End Sub

More difficult? It seems like "extremely more difficult" instead. :) You may be better off just removing all of the IMG elements from the DOM before they're displayed.

Seeing as the other question is resolved, you probably don't need this answered anymore. Feel free to post in Community Support asking for this to be PAQ'd and points refunded. I'll agree to that.
