How do I derive this from the arguments handed to the event handler? -- Mark Jacobs www.jacobsm.com Back to top Hans Galema Guest Posted: Mon Jan 08, 2007 4:38 am    Post subject: Re: CppWebBrowser OnNewWindow2 event handling Mark Jacobs wrote: Quote: The problem I am having is deriving the URL that will be launched, if I do allow the pop-up. How do I derive this from the arguments handed to the event handler? You do not need to know the URL as all you have to provide is a pointer to an instance of TCppWebBrowser that should display the new page. So you could instantiate a new form (containing a TCppWebBrowser) here TForm1 *Form1 = new TForm1(0,false,0,0); *ppDisp = Form1->CppWebBrowser1->Application; Hans.

However, I am not letting the pop-up launch normally (for several reasons) in another IE instance. I want to control the app launching the URL. That is why I need the URL. I have seen a solution that invovles letting the instance start, but grab the URL and cancel the navigation inside the OnBeforeNavigate event, but I don't like that solution. Is there any way of getting the intended URL from the LPDISPATCH parameter? -- Mark Jacobs www.jacobsm.com Back to top Hans Galema Guest Posted: Mon Jan 08, 2007 6:20 pm    Post subject: Re: CppWebBrowser OnNewWindow2 event handling Mark Jacobs wrote: Quote: ...I want to control the app launching the URL.

Is there any way of getting the intended URL from the LPDISPATCH parameter? At the moment I don't know. What I found was a thread with Subject: Getting Target in NewWindow2 <quote> Another approach I've tried is capturing DWebBrowserEvent::NewWindow instead. Since that handler, unlike NewWindow2, gets the target, as well as the URL, I could just do cancel the request and create the window myself. But that breaks the window relations within the scripting engine, so it was a less than satisfactory solution. </quote> Now NewWindow is not public. But maybe you can make a class that makes it public. By the way: You are not generating the html yourself I suppose. Hans.

By the way: You are not generating the html yourself I suppose. Again, many thanks. Some good ideas here. But it does seem as if M$ have sabotaged a really useful pop-up blocker event, and replaced it with something much harder to work with! I have dabbled with the header file shdocvw_ocx.h but I cannot get the OnNewWindow event from TCppWebBrowser_V1 into the TCppWebBrowser class definition.
