Webbrowser

[Vadim Rapp]

Hello,

I want to create a webbrowser object programmatically, navigate to a URL,
and then analyze the document.

I create the following code (simplified):

Dim ie as new webbrowser
ie.navigate "http://www.google.com"
do while isnothing(ie.document)
threading.thread.sleep 1000
loop

This does not work; there's no error, but browser object does not navigate
anywhere. Same as if I declare the ebject with withevents, navigate, and
then expect callback - it never comes.

Navigation works if I create a separate form and put webbrowser control on
it.

Why it does not work as an object?

thanks,
Vadim Rapp

Thanks, but the problem is, I need to analyze the retrieved document. With
webrequest, I get a text stream, and I don't see how I can easily convert it
into htmldocument. If I save the stream to file and then navigate to it, the
relative links in the document will not resolve correctly.

I was just curious why webbrowser so much insists on being in a container.

thanks,
