DanYELL10-Jan-02 13:28 DanYELL 10-Jan-02 13:28  When I start a new project, I have Edit at the top with undo, cut, copy and paste. How can I activate these options? If I click the right mouse button on an edit box, then alittle box pops up which lets me access these commands. But I would really like to know how to activate the menu bar Edit command as well. It just seems like a waste unless its activated. Please, any response any one can give me will be greatly appreciated.

Christian Graus10-Jan-02 14:40 Christian Graus 10-Jan-02 14:40  The edit box is handling these for you in the edit box. To activate them in the menu, you need to write code that handles undo for your app, and cuts/copies/pastes to and from the clipboard.

There's still no way that the items will ever be visible unless there are functions linked to them, or does MFC provide basic, text only ones by default ?

Nish Nishant11-Jan-02 3:28 Nish Nishant 11-Jan-02 3:28  Actually MFC provides cut, copy and paste functionality if you use those IDs. But your edit control or view must be in focus. Create an SDI project using app-wizard and set the CView to CEditView. Now build and run it. Select some text and you'll notice that the cut, copy and paste in the edit menu are now active and fully functional. In a normal [say a formview] view when we have an edit box, the problem is that when we select a menu item, the edit box goes out of focus and thus the menu items are disabled. But if we have a toolbar and we use these IDs for 3 of the buttons, then we can cut, copy and paste Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Re: how can I activate the undo, cut, copy, paste options under Edit? Christian Graus11-Jan-02 10:15 Christian Graus 11-Jan-02 10:15  Well, you learn something every day. I've always written code that copys/pastes images so I'd never noticed that functionality.

What is the best base classes to use for the splitter window to hold a list of variables which can be clicked to change the output in the main CSrollView derived view class? I am experimenting at present and am just trying to split one window simply by overriding CreateClient as follows BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { return m_wndSplitter.Create (this, 2, 1, CSize (8, 8), pContext); } But I keep getting an ASSERT(pContext != NULL) Why is this and how can I fix it? Re: Static Splitter window Nish Nishant10-Jan-02 16:22 Nish Nishant 10-Jan-02 16:22  You can't use Create for static splitters, you need to use CreateStatic Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut WYSISWYG HTML View Matt Newman10-Jan-02 11:29 Matt Newman 10-Jan-02 11:29  I am writing an WYSISWYG HTML editor and was wondering were I should start, a RichEditView capturing the saving and convert it or does someone have a better idea? - Matt Newman - Matt Newman -Sonork ID: 100.11179:BestSnowman Re: WYSISWYG HTML View alex.barylski10-Jan-02 13:17 alex.barylski 10-Jan-02 13:17  You could probably use the RichEdit however using the MSHTML editor would be easier and have more fetures by default. I think this is the same COM object that outlook express uses. I'm writting a editor as well, however i've recently decided to settle for non-wysiwyg.

When I call AfxBeginThread or _beginthread and the function that I have putted as a parameter in one of them. Is one of those functions calling the function that is specified in AfxBeginThread or _beginthread called and then return to next code after calling AfxBeg.. or _beginth.. while the function parameter still in use? I can't explain but look here: void Afunction() { AfxBeginThread(ThreadFunc, ...) // Now try do something else RasDial(); // Perhaps a bad example but.. } Now what I tried to explain: When now AfxBeginthread is called and the ThreadFunc is called, imagine that it's a very big function that checking the harddrive for mp3 files and then rename all of them and then try to move them to another harddrive, is this procedure running at the same time that RasDial is called or whatever code anyway that comes after AfxBeginThread?? Where an I read about multithreading?? ------------------------------ ©0d3 ©®4©k3® - That's me! ------------------------------ Re: Multithreading and the AfxBeginThread(..) func Joaquín M López Muñoz10-Jan-02 11:00 Joaquín M López Muñoz 10-Jan-02 11:00  Well, a thread is like a microprogram that runs separately from the main thread (though accessing the same global variables). From the point of view of Afunction, AfxBeginThread(ThreadFunc, ...) starts another thread and returns immediately (i.e. whitout waiting for ThreadFunc to complete), going then to RasDial. So, from the user's (and the programmer's) perspective both routines (TreadFunc and RasDial) are executed in parallel --that's the whole point of multithreading. The issue of different threads accessing global variables simultaneously can cause a lot of problems that you must work hard in order to prevent. When programming in a single-threaded environment, you implicitly assume that your variables remain unchanged while you're not dealing whith them --now this is no longer true, and a rich theory about simultaneous access to shared resources has been devised to help you design error-free multithreaded programs. This theory includes concepts as synchronization (waiting for completion of another thread's piece of code), exclusive access (methods to reclaim and grant access to some resource to one thread at a time) and more. You can find several tutorials about multithreading on the net, just spend some minutes with your search engine to locate lots of them. The concepts underlying multithreading are rather platform-independent, so a good tutorial on multithreading in, say, Java will be worth reading tough you're targeting MFC. As a starting point, here's MSDN article Multithreading Tasks.
