I had Launched a Internet Explorer from CreateProcess() ,I want to know how to get HWND of the Internet explorer from PROCESS_INFORMATION structure . tried EnumWindowProc but i am bumb Didn't get anything it gives me handle of Addressbar etc and i want IFrame handle .
Thanks
I already answered you this question in your previous thread (my reply)
Did you read it?
Did you try? What was a problem you get while trying it?
yes i read your ans properly ....In My App only i had used createprocess to launch a IE hey thanks right now your ans is pretty clear to me . Just now got a idea .Let me check itQuote:

Hi Victor according to your suggestion had tried couple of things by making a sample app. Getting proper process ID but still Enum WIndow gives the handle of AddressBar or some other window.Funniest thing some time hook also doesn't work .Anyway that is not a problem only problem is this Process Id in case of IE
ThanksCode:

I wonder, dear humptydumpty,
is it your credo to ignore any indentations in your code? :confused:
I am sorry Victor Just copy paste from VS .Actually i am little bit stuck here So just forget to do this. This is really nasty Geetting problem with IE then VLC media player etc. due to these 2 issue i am just stuck.Quote:

Just curious. How did you get the syntax coloring? Is that a VBCode option I don't know about, or did you manually color all that text in the editor?
And Victor a Interesting pointQuote:

Just Copy Paste Visual Studio Code.Quote:

I am quite close .Now getting proper process Id etc. Had varified from SPY++ .Now the only problem is Under my EnumThreadWindowProc() when i try to get HWND from ProcessID it return me the handle of TabWindowClass Not the IEFrame Window Handle. SO how to get the IEFrame Window handle from this processID.
Problem Solved:- :p
Thanks
Use Spy++ to obtain the relationship between these IE windows.
Those are TabBrowser Window .this problem occur in case of multilayer window like MSOutlook and IE etc .now how to get main window HWND from this process id . I have something in my mine .But i want to know Ur opinion first.in case of vlc i can c processid is same but no relation between window
Thanks
