It turns out that the predetermined development environment is VC 6.0 but. It is found that the class found on VCBase can only work on VC7.0. At the same time, some programs developed with VC6.0 are easily erroneous in XP, so it is finally decided to use VC7.0 that is also VC7.0 in VS2003.
I believe that the next progress will increase. However, it is found that VC7.0 is just a lot of functions to disassemble the original ClassWinzard.
Feel some features of VC7.0 may have some users who adapt to WindowsXP. Converting IDE is less suitable. But after the feeling of proficiency, it may be better than the efficiency of using VC6.0 now.
