Is there a limit of characters for DocumentText of the WebBrowser control? When I try to copy it to the clipboard, it is always truncated. Any way around this problem?

I've been trying to learn more about the WebBrowser control lately.
Not an expert at all, but I found a couple links that seem to apply.
I did read that there is a limit based upon memory, and clipboard.
You could check by shortening what is to be copied, just as a test.
Then you'll know if it's a memory/clipboard limitation or not.
Dial it in to the right size, and you'll know exactly what the limit is, if any.

Reason: link
It could be a script preventing it. Same one blocking popups maybe.
Well, there is no script blocking popups. If you are referring to my other thread...you can see that the issue was that popups where opened in a separate IE instance. This would cause the session data to not be seen. Therefore the server-side would not initiate the data I wanted to see.
Just so you know...This text-replace implementation is to replace the popup code and make them open in the same window.

It's for sure not the clipboard because even just outputting it from my project, no clipboard involved, it gives the truncated version.
I don't see why memory would be the cause here, because there is more than sufficient for this ~40k document.
I went thru another situation involving IE7. My VB6 program worked on three machines, until client bought Vista laptop. All of a sudden, the vb app was timing out after about two minutes, instead of taking 5 minutes.
It wasn't until we installed IE7 that both the compiled app, and in the IDE now failed.
Finally made the connection, and looked it up. The default timeout was changed from ie5 to ie6 and then ie7. Registry hack fixed things.
No, it's not XML. However, it actually seems as though DocumentText has a character limit. If I just set it to write to a text file, it still is truncated.

I think you're missing the point. I need the pages full functionality. That includes JavaScript and forms. There is no way to go from a screenshot back to the complete original code including scripts and forms.

There are converters out there, but I've never used them, so I don't know if it would work like that.
When it gets tructated, have you counted the characters remaining?
That may be a clue, that will help in the search for a documented limitation.
I tried a few test runs, and I couldn't reproduce the problem.
If you can give me a number(limit), then I can test it, by trying a larger number of characters here.
A partial diagnosis can be made.
If we match, then it's a control limitation, if not, then the limitation is local to your machine, for whatever reason.
I was doing a dumb thing. I just realized that I was trying to evaluate the DocumentText property when the title changed, not when the document was completed.
