Changing url in webbrowser control
Hi,
In order to avoid loading images for "some" urls that I go to the the webbrowser control, I've tried the following code. The problem is that none of the relative links work in the webbrowser when the page loads. I think that's because the locationurl is still about:blank. I try below using the putproperty method of the webbrowser control to set the locationurl property manually however it doesn't seem to work. Any ideas?
Private Sub Form_Load()
'First time round, make sure
'there is a document in the webbrowser
WebBrowser1.Navigate ("about:blank")
'Navigate to a page without images like this:
NoImageNavigate ("http://www.google.com")
End Sub
Private Sub NoImageNavigate(myURL As String)
Dim myhtml As String
myhtml = Inet1.OpenURL(myURL)
'Writing this string to the webbrowser will be enough
'to lose the relative references to images.
'But the following 'replaces' will kill
'any absolute references also. The browser
'will ignore the 'bad syntax' that this creates
myhtml = Replace(myhtml, "<img ", "<p ")
myhtml = Replace(myhtml, "<IMG ", "<p ")
myhtml = Replace(myhtml, "< img ", "<p ")
myhtml = Replace(myhtml, "< IMG ", "<p ")
WebBrowser1.Document, "LocationURL", myURL
With WebBrowser1.Document
.open
.write myhtml
.Close
End With
End Sub

WebBrowser1.Document, "LocationURL", myURL

.open
.write myhtml
.Close
End With
End Sub
And another way:
Dim iTag As IHTMLElement 'Reference the Microsoft HTML Object Library
For Each iTag In WebBrowser1.Document.All.t
iTag.src = "c:\repl.jpg"
Next
Dim iTag As IHTMLElement 'Reference the Microsoft HTML Object Library
For Each iTag In WebBrowser1.Document.All.t
iTag.src = "c:\repl.jpg"
Next

Hi,
Actually, what I was trying to do is download without downloading the images. That's why I used the inet control to download the html, then took out the old not working image tags. My code works but then none of the links work.

Good thinking. I hadn't thought of that approach. How would we retain the necessary cookies though so that links would work? By the way, the code for some reason seems to be loading images anyway. Not sure why that would be.
Hi jodyglidden,
I've been following your quest to control what the Webbrowser downloads. Unfortunately there does not seem to be a good answer for VB6.
I downloaded the Emorcillo project and got the same error you reported in your other question. What little documentation there was stated the code was tested with Windows Me (not NT, 2000, XP).
So far the only viable solution seems to be wrapping the Webbrowser control inside a C++ ATL project in order to catch the request for DISPID_AMBIENT_DLCONTROL. But this is beyond me, and the ones capable of doing so probably aren't using VB anyway!
I'll keep my eyes open for you.
Best of luck.

Hope it helps!
