Wide String to Normal

WideCharToMultibyte() is a good option

Inspecting the original question with my eyes (something I do not always do before I answer), I see that it is asking for a conversion from a wchar_t (not a pointer?) to lptstr which is quite a different can of worms. Since the t is dependent upon a preprocessor define, I would make a preprocessor wrap around the conversion.

#ifdef UNICODE
// define a converter here for just taking the wchar_t and making a zero
//delimited unicode string from the one character
#else
// define the converter to make the conversion on one char
//(in the appropriate param) with WideCharToMultiByte
#endif

I would normally answer this question as the previous two posts, but I think sometimes I assume too much, so I though the original poster might like a start in this direction. Of course, I didn't go into the actual definition, because I was a little confused about whether the intent was really wchar_t or wchar_t* (and thus whether to go to all the trouble of address referencing and possible zero-termination appending), but those details can easily be filled in!

[Yves : please avoid long code lines ;)]

wchar_t s1[30]=L"abcd";
char s2[30]="";

sprintf(s2, "%S", s1);

printf("\n%S\n%s", s1, s2);
