    call webbrowser.Navigate within a thread via post message to UI thread

    call webbrowser.Navigate within a thread via post message to UI thread

    i wan to navigate to a website using my webbrowser2 activeX i made. but i need to run threads to execute a webbrowser.Navigate. because webbrowser.Navigate can only be called by the main user interface thread, inorder to use it from within a browser, i would be using the postmessage command to the main thread with a custom message

    heres my custom message

    Code:
    // my custom messages
    #define WM_GOWEBSITE (WM_APP + 1)
    here is the handler for WM_GOWEBSITE
    Code:
    void Dlg::On_WebsiteVisit() 
    {
    	m_webbrowser.Navigate("yahoo.com", NULL, NULL, NULL, NULL);
    	return;
    
    }
    from within my thread, this is how i posted WM_GOWEBSITE
    Code:
    	
    	th_thread->PostMessage( WM_GOWEBSITE , 0,0);
    after running debug , i am very sure the message got posted. But the problem now in the release version is that the page simply does not load.hovering my mouse over the activeX control i get the "half cursor,half hour glass" mouse cursor. the debug version is fine.

    does anyone know what is going on?
    can anyone please help me? thanks in advance!

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
