Re: problem with DLL and CString Alexander M.,28-Mar-05 3:41 Alexander M., 28-Mar-05 3:41  When you include a MFC header file you must not include windows.h. MFC does include it!! Furthermore you should better not use parts of MFC in an non-MFC application. Don't try it, just do it! Re: problem with DLL and CString eli1502197928-Mar-05 3:58 eli15021979 28-Mar-05 3:58  Thanks for you prompt reply. I need to make a regular dll with objects of MFC(i.e CString). Which DLL workspace should i choose in the MSDEV? regards, Eli Re: problem with DLL and CString Blake Miller28-Mar-05 4:39 Blake Miller 28-Mar-05 4:39  If the program that will load the DLL might NOT be MFC, then choose MFC AppWizard (dll) as the project type. Then in Step 1 of the wizard, make sure you choose "Regular DLL with MFC statically linked". This will allow your DLL to use MFC but the parent application does not have to be an MFC program. Don't pass MFC objects between your DLL and your program, or you might experience memory issues and the created MFC objects are not necessarily from the same memory pools.

I can't find anywhere the windows.h. Re: problem with DLL and CString Blake Miller14-Apr-05 4:17 Blake Miller 14-Apr-05 4:17  If the problem is the 'windows.h' appearing in your files, is it possible both of you can try the include file dependency checker tool from CodeProject to see if that will help you locate it? http://www.codeproject.com/useritems/includefinder.asp How to display MultiLine in MFCGrid Cell UrbanBlues28-Mar-05 2:26 UrbanBlues 28-Mar-05 2:26  Hello I would like to add multiline text in the MFCGrid ... Is it possible to do such things without changing anything to the original code ? Thanks for your help Thierry Re: How to display MultiLine in MFCGrid Cell PJ Arends28-Mar-05 6:44 PJ Arends 28-Mar-05 6:44  It already supports the display of multiline cells. You just have to clear the DT_SINGLELINE format. pCell->SetFormat((pCell->GetFormat() & ~DT_SINGLELINE) | DT_WORDBREAK) Tooltips and in place editing need work though.

Honoured as one of The Most Helpful Members of 2004 Runtime selection of Multiple String Table CookieT28-Mar-05 2:25 CookieT 28-Mar-05 2:25  In my project I have, say, three string tables for language packs - English, French and German. After building all string tables(having same ID) into the .exe file, how can I control which string table the program should use during the runtime? That is to say, if I want the outcome to be of English interface, is there any way of coding to manipulate the choice of the string table used? Great thanks in advance for your reply How do I change the tooltip of a title bar button?

Re: How do I change the tooltip of a title bar button? Alexander M.,28-Mar-05 13:41 Alexander M., 28-Mar-05 13:41  Have a look at WM_NCHITTEST and WM_NCMOUSEMOVE. Maybe you can handle then in your own functions and create a tooltip yourself. Don't try it, just do it! AES implementation Anonymous28-Mar-05 2:03 Anonymous 28-Mar-05 2:03  hi,, Anyone familiar with the AESalgorithm There is an implementation of the AES algorithm in the below link. If u download it.. http://www.thecodeproject.com/cpp/aes.asp in Table.h (1.) Why have they used s boxes in ‘int’s? why not const int CRijndael::SBox[256] rather than ---const char CRijndael::SBox[256] and replace the negative values with positive? (2.) What does const int CRijndael::sm_T1[256] …. const int CRijndael::sm_T8[256] tables correspond to? (3.) and const int CRijndael::sm_U1[256]…const int CRijndael::sm_U4[256] tables correspond to (4.) also const int CRijndael::sm_shifts[3][4][2] tables correspond to? tnx Re: AES implementation David Crow28-Mar-05 2:28 David Crow 28-Mar-05 2:28  Why not pose these same questions to the article itself?

All is fine. But when running the program on other machine like XP Pro SP1 or Win2000 Pro SP4 or on XP Home edition, my program does not run due to ntdll.dll (function RtlIpv6StringToAddressExW does not exist in preview version of ntdll.dll) And with the app dependency walker and can see the difference between those ntdll.dll. I do not need to update my other system to XP Pro SP2; What can I else do. Thank you in advanced. Pierre Kande Re: Program compile witn XP Pro SP2 not run on XP Pro SP1, Home and Win2000 SP4 Michael Dunn28-Mar-05 4:38 Michael Dunn 28-Mar-05 4:38  It sounds like you are calling an API that was added in SP2. Your only choice is to not call it on pre-SP2 systems, and find/write some equivalent code to use on those systems. --Mike-- LINKS~!

I have link my app to the all DLL of windows and not to the DLL install on my OS. and running the program in other system, all is fine. This mistake is from MS, because it cause program build on XP Pro SP2 can run in older version if you link only with the old version dll. have it in mind. Re: Program compile witn XP Pro SP2 not run on XP Pro SP1, Home and Win2000 SP4 Alexander M.,28-Mar-05 13:36 Alexander M., 28-Mar-05 13:36  I've never heard about that api "RtlIpv6StringToAddressExW", and even google doesn't know it. Nevertheless, take care when using ip6, it is often not yet supported by windows. Don't try it, just do it! Re: Program compile witn XP Pro SP2 not run on XP Pro SP1, Home and Win2000 SP4 pierrekande28-Mar-05 20:04 pierrekande 28-Mar-05 20:04  Dear Alex, Thank you for your reply to my request: In fact if you have the VC tools: "Dependency Walker", and if you have XP Pro SP2, if you open the ntdll.dll, you will see the following function that MS have added and that are not in version XP Pro SP2. "RtlIpv4AddressToStringA RtlIpv4AddressToStringExA RtlIpv4AddressToStringExW RtlIpv4AddressToStringW RtlIpv4StringToAddressA RtlIpv4StringToAddressExA RtlIpv4StringToAddressExW RtlIpv4StringToAddressW RtlIpv6AddressToStringA RtlIpv6AddressToStringExA RtlIpv6AddressToStringExW RtlIpv6AddressToStringW RtlIpv6StringToAddressA RtlIpv6StringToAddressExA RtlIpv6StringToAddressExW RtlIpv6StringToAddressW. So when I build my App, the linker use the ntdll.dll and call the function RtlIpv4AddressToStringW and RtlIpv6StringToAddressExW. and those function are not defined in the preview version of ntdll.dll. My version is: 5.1.2600.2180 The call to those function is made from WS2_32.dll (at version 5.1.2600.2180 to )that call it from ntdll.dll never try but make it. &quot;ref&quot; equivalent keyword in C++ kd834128-Mar-05 1:34 kd8341 28-Mar-05 1:34  I am using VC++.net 2003 to access matlab with C API, I have to call a function which is programmed in C#.

Again about Neural Networks Rassul Yunussov28-Mar-05 1:09 Rassul Yunussov 28-Mar-05 1:09  Well, i'm trying to make an application, that can view the AVI file with the cars and recognize the numbers of cars. So I've already found the place of number - but accuracy is bad, the point that I positioning my view is not always in the center of the number. So for example the number can be in the center, in the conrers e.t.c. And the chars are different size... The next step is to recognize it... Well - this is the main problem - i can't solve it... I don't know how to dot, do i have to teach my neural network for different size of characters ( it is very hard, because of a load of data), and another way is to find the characters ( i don't know how), get it size and then fit it to my recognition window... Does anybody have had deal with such problems???
