. A sample code to change the fonts in your web browser using webbrowser control. void CMyBrowser::SetFont(int nFontSize) { m_pDisp = NULL; // IDISPATCH pointer LPOLECOMMANDTARGET pCmdTarg = NULL; m_pDisp = m_WebBrowser2.GetDocument(); // get the idispatch pointer from webbrowser control ASSERT(m_pDisp); //check for validity m_pDisp->QueryInterface(IID_IOleCommandTarget, (LPVOID*)&pCmdTarg); //query for IID_IOleCommandTarget interface ASSERT(pCmdTarg); // check for validity […]

. This is the code for implementing the “View Source” option in Internet Explorer void CMyBrowser::OnViewSource() { CWnd* pWnd = NULL; CWnd* pwndShell = m_WebBrowser2.GetWindow(GW_CHILD); // get the webbrowser window pointer if (pwndShell) { pWnd = pwndShell->GetWindow(GW_CHILD); //get the child window pointer } if(pWnd != NULL) { WPARAM wParam = MAKELONG(IDM_VIEWSOURCE, 1); //convert to unsigned […]

Many applications need to “remember” the last window position and status (minimized/maximized/normal). This seemingly trivial task holds a few little-known subtleties, so I thought it might be helpful to show code that handles these things correctly. Saving the window’s position is straight forward: void CMainFrame::OnClose() // message handler for WM_CLOSE { // Save main window […]

I add here the code that could be used to add multiple views to a document, in a MDI application. I usually make database applications, and I don’t want that the document to be created/destroyed by the framework, so I create the document myself (and of course I destroy it J ), and in document’s […]

I think there is a new/simpler way to create new views attached to an existing document using VC++ 5.0. I think it is a cleaner implementation since it uses new hooks that MFC provides rather than having to work with the CCreateContext’s. Assuming the following are already declared in the app: CMultiDocTemplate * m_pTemplate; CWhateverDocument […]

Download files 77K. What is a MultiSingle document. In most applications, it is necessary to have one document with many views. The SDI architecture is for one document and one view and the MDI architecture is for many documents with many views. My goal is to have an MDI architecture with one document and many […]

Often I have been coding away and realized that to get exactly the behavior I would like I would need to change the Window class for my View window. Upon looking into the Developer Studio help file, and perusing the help to AfxRegisterClass, I’d realize that this could be a bit more work than one […]

Download files 497K. What is a MultiSingle document. For Multisingle document interface, please refer to the MSDI with little change to the class name CviewFrame -> CMSDIViewFrame etc.. Multisingle document with DAO Access. This sample shows a MSDI sample application to open an MS-ACCESS Database as an only one document. If you change to another […]

Microsoft outdid themselves when they designed MFC such that applications are automatically named according to the document view paradigm. When you use MFC to create either an SDI or MDI application, your main window is probably called something like “Untitled – MyApp.” If you don’t particularly care for the document view paradigm, other than perhaps […]

Many times in an SDI interface the programmer would like to have many views of the same document.  Look at the MFC sample collect.  It consists of an SDI app which has nine different views for each of the data types in its document.  The view is switched by selecting a menu item.  There are […]

Here is a class that implements an MDI Frame (CMDIChildWnd) which shows a number of variable views (up to 4 views). The Class (CBaseVarFrame) is reusable. It implement four new commands : ID_SPLITTER_NESSUNO (Just Default View,no splitter) // status = 0 ID_SPLITTER_UNO ( 2 Views ,Default View on the left pane,1 view in the right […]

It implements an MFC extension class that adds IntelliMouse panning to CScrollView or any window with scroll bars. There is already one example of this in circulation (George Shepherd and Scot Wingo at MSJ Dec97) but the implementation is quite weak. Their version caused lots of flickering, incorrect paintings etc. So I wrote my own […]
