IE7 protected mode hWnd problem
hello,
i'm trying to get the hWnd of a IWebBrowser2 control.
if i'm working on xp, everything is ok.
but with Vista - things different. hWnd returned is not valid. (IsWindow - fails)
any ideas why?
How can i solve this?

# 1 Re: IE7 protected mode hWnd problem
Can you post the code you are using to get that handle, also have you tried using spy++ on vista to see if the class name of web browser window is same as XP ?
# 2 Re: IE7 protected mode hWnd problem
the code is very simple:
CComPtr <IWebBrowser> web;
web->CoCreateInstance(...);
web->Navigate(...);
HWND hWnd = web->getHWND();
it's from my memory, so it may be unacurate, but that's the way.
this code has nothing to do with window class name, but i checked with spy++, and the result of getHwnd is not found (if protected mode is off, hWnd is found in spy++...)

Vista betas ship with IE7 , right ? Wondering if this is a IE7 thingy. Have you tried the same with IE7 on XP ?

Aparently there are changes with accessing window handle etc. in protected mode, here is more information.

In XP there is no problem, because there is no Protected mode of IE7.

I already read it. nothing about my problem...
I can make a workaround if i'll be able to start the CoCreateInstance function as a Low Integrity (Protected Mode).. like the function CreateProcessAsUser. Does anybody knows something about it?
Thanks.
