Re: changing user drawn bitmap button V.29-Sep-04 22:38 V. 29-Sep-04 22:38  I think I would use an imagelist. Load all bmp's in there and switch accordingly. hope this helps. (eg. for setting an icon to a button I did this: icon = (HICON)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDI_PRINT), IMAGE_ICON, 16, 15, LR_DEFAULTCOLOR);<br /> pPrintbutton->SetIcon(icon);<br /> I presume it's round about the same for a bmp) "If I don't see you in this world, I'll see you in the next one... and don't be late." ~ Jimi Hendrix LNK2005, Plz help.. enoloo_don29-Sep-04 17:38 enoloo_don 29-Sep-04 17:38  --------------------Configuration: xt3 - Win32 Debug-------------------- Linking... nafxcwd.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in libcpmtd.lib(delop.obj) xt3.exe : fatal error LNK1169: one or more multiply defined symbols found Error executing link.exe. xt3.exe - 2 error(s), 0 warning(s) What causes this?

Tips One of the following may be a cause: The most common cause of this error is accidentally linking with both the single-threaded and multithreaded libraries. Ensure that the application project file includes only the appropriate libraries and that any third-party libraries have appropriately created single-threaded or multithreaded versions. The given symbol was a packaged function (created by compiling with /Gy) and was included in more than one file but was changed between compilations. Recompile all files that include the symbol. The given symbol was defined differently in two member objects in different libraries, and both member objects were used. An absolute was defined twice, with a different value in each definition. This error is followed by fatal error LNK1169. fuzzy logic n other stuff styx1300129-Sep-04 16:51 styx13001 29-Sep-04 16:51  hi, I'm a developper and i'm lookin for books oriented to non beginner on different subjects : - comrehensive information on run-time librairies and their ideology (ie memory working, the dipatching of messages between objects and their ordonation, error enhancing with (very) old dlls) - fuzzy logic - neural networks - algorythms of mostly used video and audio formats (compilable and shareware if exists) - a comprehensive one on multithreading and if possible parrallelism thanks if you can help me, being jobless i prefer stuff on line or in numereical form styx Adding C++ console application classes to a VC++ MFCAppwizard project neo_sid29-Sep-04 16:11 neo_sid 29-Sep-04 16:11  Hi, I am new to VC++ and would like to know that if I have a C++ console application and want to add it to a VC++ MFCAppwizard project, how do I do it? The problem I am facing is thatwhen I add those .cpp files to the project, I am unable to compile the code as the compiler apparently is unable to resolve classes defined in the console application. To give you the exact nature of the problem, I have a C++ console application which I want to import to VC++ and add forms and UI. Is this problem something to do with "using namespace .."? I would like to get some pointers on how to solve this problem. Thanks. Sid Re: Adding C++ console application classes to a VC++ MFCAppwizard project Christian Graus29-Sep-04 16:49 Christian Graus 29-Sep-04 16:49  It's highly unlikely that your default code is using namespaces, if you've put stuff in a namespace ( and good for you if you have ), then you just need a using statement to scope it. You should just be able to add your classes, unless your classes rely on libraries that your MFC project does not use, then you need to add them to the project settings. Again, unless you added them to the C++ console project, I don't see this being the case. What errors do you get ? It's kind of hard to help you fix a problem if I don't know what the actual problem is Christian I have several lifelong friends that are New Yorkers but I have always gravitated toward the weirdo's. - Richard Stringer How to initialize const of base class Boniolopez29-Sep-04 15:29 Boniolopez 29-Sep-04 15:29  Hi, May be very simple question, but I can't find the answer.

The only way to initialize My_some_const is via constructor member initialization list. That initializes My_some_const to 10: class A{ public: const int My_some_const; int k; A(int k_):k(k),My_some_const(10){}; } class B:public A{ B(int k):A(k) } Re: How to initialize const of base class Boniolopez1-Oct-04 4:05 Boniolopez 1-Oct-04 4:05  Thanks all for your help make multiple mdi child windows scroll together mickelliot29-Sep-04 15:20 mickelliot 29-Sep-04 15:20  Hi there, I have an mdi app, child window containing a cscrollview. Obviously the user can create new child windows using the window>New Window menu item. When they have created more than one view, I would like the multiple child windows to scroll synchronously. I mean that when an active child window's view is scrolled, all the other child window's views scroll along at the same time. I can't think of a way to do this! I tried maintaining a CPoint in the document class, updated by the view whenever it is scrolled, and adding a ScrollToPosition command in the update function of the view. But it was very messy and didn't quite work correctly. Does anybody know if there's a neat clean way I can do this, perhaps sending windows messages directly between child windows or something? Thanks for any help, Mick Re: make multiple mdi child windows scroll together Ryan Binns29-Sep-04 18:14 Ryan Binns 29-Sep-04 18:14  mickelliot wrote: When they have created more than one view, I would like the multiple child windows to scroll synchronously. Any reason why? The whole point of the New Window menu item is so that users can see different parts of the same document at once. Having them all automatically scroll to the same point sort of defeats the purpose.

The idea is that each view will contain the same view of the same data, but with different parameters so that the view "looks" different. I can best explain myself by asking you to imagine an MDI bitmap editor. You load in a bitmap, which appears in a new child frame, and set its magnification to 100%. You then open a new window and set the magnification of the new view to 200%. Now, when you scroll around the 100% view, you want the 200% view to move along with it appropriately (i.e. in the same direction and twice as fast), so that each view contains the same area of the bitmap but just at different magnifications. The idea would be to make this an option for the user - i.e. they can either open two child windows and use them to view different parts of the document, or they can adjust the parameters of each view and synchronize the two windows. Mick Re: make multiple mdi child windows scroll together Ryan Binns30-Sep-04 13:48 Ryan Binns 30-Sep-04 13:48  One way would be to handle WM_HSCROLL and WM_VSCROLL in each view. Whenever the view is scrolled, get the current scroll position. Each document (GetDocument()) has a list of all the views attached to it (GetFirstViewPosition(), GetNextView()). Just loop through for each view and call SetScrollPosition().
