Re: in fact, STL Problem... LX13-Sep-01 6:45 LX 13-Sep-01 6:45  Yes, it's right !! What I want to do is based on STL : ------------------------------------------ typedef struct _MYSTRUCTURE { long lType; long lSubType; }MYSTRUCTURE; typedef std::vector<long> lID; typedef std::map<mystructure, lid=""> myMap; ------------------------------------------- But when I do a 'find.' on myMap, STL can't find my vector in searching on MYSTRUCTURE 'cause it can't compare : ... ---- MYSTRUCTURE myStructure; myStructure.lType = 10; myStructure.lSubType = 11; myMap::iterator it; it = m_mymap.find(myStructure); ---- So, I wanted to concatenated the 2 longs and using typedef std::map<double, lid=""> myMap; but, you're right : double and long are two differents animals... Do you see a solution ? LX Re: in fact, STL Problem... Tomasz Sowinski13-Sep-01 6:59 Tomasz Sowinski 13-Sep-01 6:59  Your code got scrambled - you didn't replace < and > with &lt; and &gt; Anyway, using std::pair to keep type and subtype together may be solution for your problem.

Anyway, you're response is very helpful for me !! I think that std::pair will works... Thanks you very much, Tomasz!! LX Re: C++ MAKEDOUBLE ??

UpdateResource on Win95 13-Sep-01 5:52 13-Sep-01 5:52  Are there any similiar functions to BeginUpdateResource, UpdateResoure ... that work on Windows 95,98 and not only NT and 2000? Re: UpdateResource on Win95 Tomasz Sowinski13-Sep-01 6:20 Tomasz Sowinski 13-Sep-01 6:20  No, there are no such functions on Win9x. Are you the same guy who wants to write 'small info' into executable? Tomasz Sowinski -- http://www.shooltz.com Re: UpdateResource on Win95 13-Sep-01 8:14 13-Sep-01 8:14  Yes It would really be very easy use resources, but unfortunately these functions are supported only on WinNT regards, Gregor Re: UpdateResource on Win95 Tomasz Sowinski13-Sep-01 8:25 Tomasz Sowinski 13-Sep-01 8:25  What kind of info do you want to write inside .exe? Tomasz Sowinski -- http://www.shooltz.com Re: UpdateResource on Win95 13-Sep-01 9:38 13-Sep-01 9:38  I just want to store two strings within the .exe e.g. one string would be something like "C:\Program Files\SomePrograme\some.exe" Re: UpdateResource on Win95 Tomasz Sowinski13-Sep-01 9:43 Tomasz Sowinski 13-Sep-01 9:43  Why is it important? Can't you store this information somewhere else? (registry, .ini file) Tomasz Sowinski -- http://www.shooltz.com Re: UpdateResource on Win95 13-Sep-01 9:51 13-Sep-01 9:51  I just want to know HOW it works, and IF it works. But the hint from Joaquín M López Muñoz in the reply above helped me a lot, I will first try to use these functions Re: UpdateResource on Win95 Tomasz Sowinski13-Sep-01 9:55 Tomasz Sowinski 13-Sep-01 9:55  I just want to know HOW it works, and IF it works. Knowledge is the key to power Even with these functions, you'll still face the problem with writing to running .exe.

Is there anyway I can add it now? Thanks. Re: Context Help Ganesh Ramaswamy13-Sep-01 7:12 Ganesh Ramaswamy 13-Sep-01 7:12  s. u can. wizard is the one that adds code for u. u can also add the same code at any point. there is something called as HtmlHelp. Try using it and implmentating context sensitive help. Documentation are there in MSDN for implementing this. Or compare to source codes one with Context-help checked and other unchecked and add the differencing code by hand. thats it Ganesh.M.Ramaswamy Logging to a text file User 988513-Sep-01 5:12 User 9885 13-Sep-01 5:12  I need to implement logging to a text file. The logged messages are small, but there can be huge number of them. But, I want to make sure that the log is intact even if the application crashes. But, if I open and close the file for each it seems like lot of load. Do anyone have any suggestions for this? modified 29-Aug-18 21:01pm. Re: Logging to a text file Tomasz Sowinski13-Sep-01 5:21 Tomasz Sowinski 13-Sep-01 5:21  If you're concerned with "lot of load", use CreateFile with FILE_FLAG_WRITE_THROUGH flag, and keep the file open. KB article Q99794 has more info. Tomasz Sowinski -- http://www.shooltz.com Re: Logging to a text file User 988513-Sep-01 5:22 User 9885 13-Sep-01 5:22  Thank you very much for the prompt reply. I will check that out. Thanks again. - Thomas modified 29-Aug-18 21:01pm. Copying files 13-Sep-01 5:06 13-Sep-01 5:06  I have to admit, I'm somewhat new to C++, so this question may not seem like much to a lot of the readers. Using one of the common header files, is there a simple way to copy a file from place to place, modifying its name if necessary? I'm aware of how to do this using text files with fstream, but I'm curious about how to copy other file types. If anyone responding would rather give a code example that try to explain it otherwise, I'll give you a scenario... say you're aiming to write a quick program that would copy the file c:\windows\desktop\file1.bmp to c:\copyoffile1.bmp. Any help would be appreciated. Thanks. Re: Copying files Tomasz Sowinski13-Sep-01 5:09 Tomasz Sowinski 13-Sep-01 5:09  Use one of the following Windows API functions: CopyFile SHFileOperation Tomasz Sowinski -- http://www.shooltz.com Re: Copying files 13-Sep-01 5:16 13-Sep-01 5:16  Got it to work. Thanks for the help. Dependencies 13-Sep-01 5:02 13-Sep-01 5:02  In windows NT, when you would right click on a dll, you could view its dependncies and what not. How do you do that in 2000? Re: Dependencies Tomasz Sowinski13-Sep-01 5:17 Tomasz Sowinski 13-Sep-01 5:17  It's not related to the operating system. There's a program, depends.exe, installed with VC++ that associates itself with .dll files. Copy this file to W2K machine or install VC++ and you'll get 'View dependencies' option. Tomasz Sowinski -- http://www.shooltz.com C++ 13-Sep-01 4:26 13-Sep-01 4:26  I had a question for recommendations...let's say you learned some C++, and then after that, got into MFC and Windows Programming. After 2 years of that, you feel that you don't know C++ too well, but you are not too bad either..you are kind of intermediate. what book would you recommend to use for someone at this stage, trying to take his C++ to the next level, going from intermediate to senior? Re: C++ Michael P Butler13-Sep-01 4:39 Michael P Butler 13-Sep-01 4:39  It depends on what you mean by going to the next level. What do you want to learn? In my experience, books can only take you so far with C++. After that you learn a lot more by coding and making mistakes (and correcting them). What do you feel you lack? Michael
