Iam a developer comfortable with basic VC++ environment.Im not aware of the packaging of executables & implementation stuff.

I have a Win 32 Console Application which Im building on Win 2000. It uses the following C API's and string functions
like bsearch, strstr,memset and complex pointer logics.

RegOpenKeyEx
RegQueryValueEx
RegSetValueEx
RegCloseKey
RegCreateKeyEx
CreateFile
GetFileSize
ReadFile
SetFilePointer
WriteFile
CloseHandle
DeleteFile

I have the following questions.

The code is already been built as VC++ 4.0 Win NT exe & its size is 66.5KB. But when I build in VC++ 6.0
Win 2000 its size is 68.0 KB.

1.Can this copy Im buidling in VC++6/Win 2000 run on Win NT. Or will I have any backward compatibility problem.

2.The Win NT and 2000 machines are already running the exe built on VC4.0/Win NT & should be having the neccessary environment.
Is it enough if I just give the Win 2000 exe alone which I build in Release mode?. Since the size is more in Win 2K, will I have any problems ?

Windows and VC++ experts please advice.

Thanks,
Indu

I strained my mind hard to find out the problem here, without much luck. ALL your applications are
running EVERYWHERE you want them to run. Honestly speaking I like to have such problems all the
time. However, if its all about those extra 1.5 KBs, well, I would say they shouldnt be the source
of your apprehension.

Still if you want a suggestion I would say that VC++ versions shouldnd be much of an issue here.
Usage of APIs, however, would make me feel more comfortable if you just build the app that you wanna
run on 2000 - on 2000 and the one you wanna run on NT - on NT. The one you built on NT should run on
both though.
Do let me know if u think I didnt understand your problem correctly or if you have something else to say on the issue.

Welcome to the forum, and thanks for your contributions here.
