Also can you explain how to assign consequtive identifiers to the menu items? I`ve tried using a UINT called count which increments, but rather sadly it failed me. Thanks again Steen, Alan. AEGC Re: Message Mapping Steen Krogsgaard23-Oct-01 4:38 Steen Krogsgaard 23-Oct-01 4:38  Well, I haven't actually done this myself so I guess it's on a rather academic level The MRU in MFC works by using a range of identifiers for the MRU items on the file menu. You could look at the MFC source to get some ideas. But from the top of my head I think MFC reserves 16 identifiers (ID_FILE_MRU1 to ID_FILE_MRU16, not sure about the names). This of course means that there's a max of 16 items on the MRU list. It then maps this range to a function (OnFileMru maybe?). Since the ID of the selected item is passed to the message handler you can surely take it from there. So what you'll need is a first identifier and a maximum possible last identifier (there's nobody preventing you from setting it to first id + 200, that should kindda cover it, right?), and some assurance that your IDs are not used by other menu items. Those identifiers that are not in use at any particular moment will not be selectable and will thus not generate any WM_COMMANDs, so there's no need to sanity-check the ID that caused the WM_COMMAND in the handler (but I would do it anyway, just out of paranoia Cheers Steen.

I would like to dynamicaly change the language of the standard windows as "Print setup dialog" or "Print preview view" and standard messages as "Please enter a number." when you type a character in a edit control wich is associated whith a real member variable . I change the language ID with SetThreadLocal, it works for my own resources but not for these windows and stringtable. I try to modify the path of the afxres.rc or afxprint.rc in my .rc file, it doesn't work better. I found the print preview toolbar and the messages resources inside the mfc42loc dll so I maybe just have to find the English and German DLL for these resource but it doesn't work for the Print setup dialog wich depend of the System language. The solution must work either under NT4 ,Windows 2000 and XP!!! Thanks for help... ZAZA Re: Mutiple language Tomasz Sowinski23-Oct-01 2:53 Tomasz Sowinski 23-Oct-01 2:53  Yes, MFC42LOC.DLL contains the localized resources - it'll give you 'Please enter a number' and other UI elements implemented by MFC in your language. Note that MFC42LOC should be in the Windows system directory. However, it will not change the strings in common dialogs for opening/saving file, print setup etc. - these are parts of the operating system itself. The only way to overcome that is to re-implement, but it would take a lot of effort. Tomasz Sowinski -- http://www.shooltz.com Re: Mutiple language 23-Oct-01 3:15 23-Oct-01 3:15  Hello Tomasz I also found the messages and the print preview button text in the afxres.rc and afxprint.rc files. I try to include them in my own RC file but it still doesn't work. Re: Mutiple language Tomasz Sowinski23-Oct-01 3:21 Tomasz Sowinski 23-Oct-01 3:21  You should include these files only if your app links to MFC statically - in such case there's no need to use MFC42LOC.DLL. Tomasz Sowinski -- http://www.shooltz.com Re: Mutiple language ZAZA23-Oct-01 3:51 ZAZA 23-Oct-01 3:51  I have an idea: if i find the mfc42loc.dll in english, french and german, could I rename them and load the apropriate one dynamicaly ? I would like to try, I use a french version of visual C++, could anyone send other language versions of mfc42loc.dll. For the standard .rc file could I built resource DLLs and load them dynamicaly with AfxSetResourceHandle(LoadLibrary(mydll)) ? Do you think it could work ? elisabeth.sever@europlacer.fr Re: Mutiple language Tomasz Sowinski23-Oct-01 4:02 Tomasz Sowinski 23-Oct-01 4:02  if i find the mfc42loc.dll in english, french and german, could I rename them and load the apropriate one dynamicaly ? Use 'Find in Files' to locate MFC code which loads MFC42LOC.DLL - just search for 'MFC42LOC' in vc98\mfc\src. Do not change MFC sources, rather copy the code into your application and load appropriate DLL at runtime, depending on language settings. For the standard .rc file could I built resource DLLs and load them dynamicaly with AfxSetResourceHandle(LoadLibrary(mydll)) ? If by 'standard .rc' you mean resources of your app, then yes, this is the way to go. Also, you can consider placing one (main) language in the .exe. This will make working with IDE easier - you'll be able to add command handlers from ClassWizard, etc. Tomasz Sowinski -- http://www.shooltz.com Re: Mutiple language Carlos Antollini23-Oct-01 4:02 Carlos Antollini 23-Oct-01 4:02  You need to make diferent .rc files. Then you need to set te resource file where the resources will be load using the following function: AfxSetResourceHandle(HINSTANCE hInstResource); Where hInstance is the HINSTANCE that you get using LoadLibrary or AfxLoadLibrary(LPCTSTR lpszModuleName); Cheers!!! Carlos Antollini. Re: Mutiple language ZAZA23-Oct-01 20:18 ZAZA 23-Oct-01 20:18  I would like to load dynamicaly the mfc42loc.dll to choose the apropriate language. I use a french version of visual C++, could anyone send me the English (UK or US) and the German versions of the mfc42loc.dll file ? Thanks elisabeth.sever@europlacer.fr Problems with debugging Matjaz23-Oct-01 2:33 Matjaz 23-Oct-01 2:33  I trace through code and I watch variable values in watch window. I have a problem with watching structures: I can only see structure's address, I can't see structure members' values. This problem does not occur always. I use Visual Studio (C++) 6 adn Win2000. What would solve this problem? Matjaz Re: Problems with debugging Andres Manggini23-Oct-01 5:07 Andres Manggini 23-Oct-01 5:07  are you sure it isn't a structure pointer ?, try adding a * in front of the variable or use "variable->member" to see the value for that field. Andres Manggini. Buenos Aires - Argentina. Re: Problems with debugging Christian Graus23-Oct-01 9:46 Christian Graus 23-Oct-01 9:46  The file <vs common="">/MSDev98/Bin/autoexp.dat contains the structures that will expand in the debugger and can be added to. You can also expand an array by putting ,# after it, for exmaple, myarray,10 will list the first 10 elements, and ((myarray+10),10 will list the next 10.

Re: Problems with debugging Andrew Peace23-Oct-01 10:34 Andrew Peace 23-Oct-01 10:34  In VC6 when you watch a strucutre there is usually a little (+) next to it which will expand the struct so you can see it's members and their values. If it's a pointer to a struct you might have to put a * in front of it. Alternatively you can use the format Struct.Value or pStruct->Value Hope that helps, -- Andrew. CRecordSet.Requery(); 23-Oct-01 2:32 23-Oct-01 2:32  Hello I use this function with access database it works properly but when I use it with MS SQL 6.5 database I havn't goten any record in my Recordset, for the same condition and identical tables. any help Best Regards Re: CRecordSet.Requery(); 23-Oct-01 21:59 23-Oct-01 21:59  Hello again I am so sorry if i bother any body, I found the error, it was in the table contents. Best Regards OnOpenDocument same file? Kristian Nilssen23-Oct-01 1:18 Kristian Nilssen 23-Oct-01 1:18  Hi, I have an MFC MDI app. If one user, running one instance of the app opens a file using OnOpenDocument then another user, running another instance of the same app opens the same file, MFC reports "Failure to open document". The app does not edit the file, it's just a viewer, so I don't care if many people are opening the document. How can I tell this to MFC? thanks, Kristian. Re: OnOpenDocument same file? Tomasz Sowinski23-Oct-01 2:27 Tomasz Sowinski 23-Oct-01 2:27  I've made an empty MFC app using wizard, added some serialization, and can't reproduce the behavior you're describing - two instances can open the same file. Did you override OnOpenDocument? If this is the case, please post the code. Tomasz Sowinski -- http://www.shooltz.com Re: OnOpenDocument same file? Kristian Nilssen23-Oct-01 2:37 Kristian Nilssen 23-Oct-01 2:37  BOOL CSaturn2Doc::OnOpenDocument(LPCTSTR lpszPathName) { // the following line fails. The serialize function is empty. if (!COleServerDoc::OnOpenDocument(lpszPathName)) return FALSE; blah blah blah... } My document is derived from COleServerDoc. Re: OnOpenDocument same file? Tomasz Sowinski23-Oct-01 2:46 Tomasz Sowinski 23-Oct-01 2:46  Oooooh - you're using OLE. My experience is limited in this area, all I can advise is stepping inside COleServerDoc::OnOpenDocument and checking which call fails - probably it'll be call to something like StgOpenStorage.
