For expample in my programm(TASM/C++) I used API-function called RegisterClassExA.
I know that this function works only in OS that has ANSI code (or I should say "charset"?) such Win98, but not in WinNT - it has only UNICODE.
So in WinNT I must use RegisterClassExW.
But I want my program to work in each OS! (Win98, WinNT,Win2000,WinXP, Win .NET
Or Im wrong and programmer can use only RegisterClassExA in both OS?
