IE 3.0 WebBrowser Control: Getting the PostData

When using the WebBrowser control to access web pages that submit form data, I want access to the posted data (URL encoded string) that is returned by the BeforeNavigate event.  I can access the URL and Header strings but the PostData array seems to be empty.  LBound(PostData) generates a type mismatch error and the TypeName(PostData) function returns "Empty" for non-form pages and "Empty()" when submitting on pages with form data.  Posted data is correctly being sent back to the server; I just can't seem to access it in the event callback.

I'm not sure if you're still interested, but I haven't seen anybody attempted to answer your question, so I'm going to take a shot at it.

I've created an application using CWebBrowser2 and trapped its events in a MDI view, in particular the OnBeforeNavigate2. I've been able to get some PostData. In my testing, I see that I get information in the argument. The PostData itself is a pointer to a variant which contains another variant. The variant in my case is a VT_BSTR variant which contains a string. Are you not seeing this?

Note that I'm using IE4.0 to try this. I unfortunately do not have the IE3.x product to see if the same thing happens there.

What is CWebBrowser2 ? I'm using the WebBrowser control that comes with Visual Basic 5.0.  You also mentioned that you are using IE4.0.  I'm not even using a browser.  I built a standalone applicaiton that allows me to browse to a page on a server and submit form data.  I should be able to trap the form data that is being passed back to the server, but I can't.  Where does one find CWebBrowser2 ?

CWebBrowser2 ist a C++ class. He use C++ instead of Visual Basic. You have to install IE4.0 to use CWebBrowser2 and with IE3.0 you can olny use CWebBrowser which is the old version.
