Hi Igor,
Thanks for the response. I would not be surprised if I am doing it wrong.
The code is below, "get_Application Success" is displayed, so hopefully you
can see something else I have missed. The error message in the browser I get
is "A runtime error has occurred. Do you wish to debug ? Line: 10 Error:
Unspecified Error".
void NewWindow2(VIEW View,
VWFIELD HostID,
IDispatch **ppDisp,
VARIANT_BOOL *Cancel)
{
IWebBrowser2 *webBrowser2 = NULLPTR;
/* Get the browser's IWebBrowser2 object. */
if (vwGetWebPtrs(View, HostID, &webBrowser2, 0) == S_OK)
{
HRESULT rc;
/* Get the IDispatch Interface. */
rc = webBrowser2->lpVtbl->get_Application(webBrowser2, ppDisp);
if (rc != S_OK)
{
if (rc == E_FAIL)
cm9util_Msg("New Window", "get_Application E_FAIL");
else if (rc == E_NOINTERFACE)
cm9util_Msg("New Window", "get_Application
E_NOINTERFACE");
else
cm9util_Msg("New Window", "get_Application Error");
}
else
cm9util_Msg("New Window", "get_Application Success");
}
}
Thanks
Leslie.

This doesn't look like a correct signature for NewWindow2 event handler.
What's VIEW and VWFIELD? How is this function called?

You seem to be trying to navigate the same browser that fired NewWindow2
event in the first place. That's not going to work. The documentation
for NewWindow2 clearly states that ppDisp should be set to refer to a
new, unnavigated WebBrowser instance.

land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

I call NewWindow2() from my Invoke Function, the View and HostID are simply
additonal parameters I provide to retrieve the iWebBrowser2 and other
interfaces.

Thats exactly what I am trying to do - open the new page in the *same*
window that fired the event (as per the subject line). So what you are
saying is that for some lame reason this method will not work unless I
create a second Browser window. What a waste of resources !!
Anyway, I have discovered that another event is available to me, namely
NewWindow3 which looks like it will be a better option. The only worry is
that I have read it is only available on XP SP2 (and I guess Vista). Is that
correct, or is it actually tied to the version of Internet Explorer that is
installed ie. If Windows 2000 updates to IE7 will this event be available ?
Is there any documentation which confirms this ??
Thansk for your help
Leslie.
