Hi all,
I'm not sure whether I should have posted it here. But couldn't find a forum where COM problems were discussed in such detail. I am programming in plain-C in VC++ 6.0 IDE. I'm trying to write a C program which will capture the BeforeNavigate2 event of an existing Internet Explorer. I'm just 5 days old to COM and after much of searching on the Web I came up with code which can connect to running instance of an IE (the code was all published on the Web; understanding it and making it compatible to C main() function style took the time).
My problem is how do I get the event BeforeNavigate2 captured by my application. My code till now is something like this

IWebBrowser2 * pWebBrowser = NULL;

			hr = spDisp.QueryInterface (IID_IWebBrowser2, & pWebBrowser);

				

			if (pWebBrowser != NULL)

			{	

				HRESULT hr;

				IDispatch* pHtmlDocDispatch = NULL;

				IHTMLDocument2 * pHtmlDoc = NULL;

				hr = pWebBrowser->get_Document (&pHtmlDocDispatch);

				

				if (SUCCEEDED (hr) && (pHtmlDocDispatch != NULL))

				{	

					hr = pHtmlDocDispatch->QueryInterface(IID_IHTMLDocument2,(void**)&pHtmlDoc);               

					if (SUCCEEDED (hr) && (pHtmlDoc != NULL))

					{

						HWND hWnd = NULL;

						pWebBrowser->get_HWND((long*)(&hWnd));

						DWORD tmPID;

						

						GetWindowThreadProcessId(hWnd,&tmPID);

						pHtmlDocDispatch->Invoke(

												LPCONNECTIONPOINTCONTAINER pConnPtCont;

						if (SUCCEEDED(spSHWinds->QueryInterface(IID_IConnectionPointContainer,(LPVOID*)&pConnPtCont)))

						{

							ASSERT(pConnPtCont != NULL);

							LPCONNECTIONPOINT pConnPt = NULL;

							DWORD dwCookie = 0;

							IUnknown* lpUnkn;

							if (SUCCEEDED(pConnPtCont->FindConnectionPoint(__uuidof(SHDocVw::DShellWindowsEvents), &pConnPt)))

							{

								ASSERT(pConnPt != NULL);

								pConnPt->[color=red]Advise(GetIDispatch[/color](FALSE), &dwCookie);

								pConnPt->Release();

							}

							pConnPtCont->Release();

						}

						else

							printf("Connection point container failed.\n");

The problem is with the Advise method. I get an error "Undeclared Identifier" with the GetIDispatch.
Any links or lead on this will be helpful as well.
Thanks all.

beaster is right, the first parameter to Advise must be a COM object that *your* application is to implement. It need not support IAdvise, though, the QueryInterface method of this interface should accept IUnknown, IDispatch and DShellWindowsEvents (shouldnt it be DWebBrowserEvents?). All events will be reported to the Invoke method of this interface.
