Warning This sample uses an undocumented command group GUID that is subject to change in the future. Although this sample has been tested to work correctly with Internet Explorer 3.0 and 4.0, there is no guarantee that these techniques will continue to work successfully in future versions. Please use caution when adding this code to an application.

The WBSampl example is a mini-browser application that illustrates how to create an application in Microsoft Visual C++ that uses the WebBrowser control. This example provides code to invoke the Find, Internet Options, and View Source items that are part of the WebBrowser control but are not exposed as methods.

In order to implement the items listed above, the following steps should be followed.

1. Define the command group GUID for the WebBrowser control as follows:

   DEFINE_GUID(CGID_IWebBrowser,0xED016940L,0xBD5B,0x11cf,0xBA,
         0x4E,0x00,0xC0,0x4F,0xD7,0x08,0x16);
   					

2. Define the CommandTarget ids for menu driving as follows:

         #define HTMLID_FIND 1
         #define HTMLID_VIEWSOURCE 2
         #define HTMLID_OPTIONS 3
   					

3. Execute a CommandTarget id as follows:

         HRESULT CMainFrame::ExecCmdTarget(DWORD nCmdID)
         {
            LPDISPATCH lpDispatch = NULL;
            LPOLECOMMANDTARGET lpOleCommandTarget = NULL;
   
            lpDispatch =
               ((CWebSurferView*)GetActiveView())->m_webBrowser.GetDocument();
            ASSERT(lpDispatch);
   
            // Get an IDispatch pointer for the IOleCommandTarget interface.
            lpDispatch->QueryInterface(IID_IOleCommandTarget,
         (void**)&lpOleCommandTarget);
            ASSERT(lpOleCommandTarget);
   
            lpDispatch->Release();
   
            // Invoke the given command id for the WebBrowser control
                 return lpOleCommandTarget->Exec(&CGID_IWebBrowser, nCmdID, 0,
                                            NULL, NULL);
         }
   					

Note that m_webBrowser is an instance of the WebBrowser control and is defined in the CView-derived class for this project. Also, nCmdID is one of the IDs defined in step 2.
