Unicode to ASCII

Hi there..

I have an application that wants to use some old code once developed on unix, then ported to win32. I am developing my app on NT4.0.

The old code resides in a static library, and needs a char* as a parameter. My problem is that I am reading this parameter from the registry, and then passing it on to this old function. What I get back from the registry is a unicode string (wchar_t or CString if you like) and I need to convert this to a char* with characters of 8bits..

I know it's possible, but how??

This sort of thing is also a problem when calling something like ExecuteSQL which expects and ASCII string and will fail if it gets something in UNICODE.

An API called

WideCharToMultiByte(...)

should help you out :)

No this is not exactly what I want.. I need something that makes me 100% sure that the characters I send to my old function is 8 bits wide, nothing more, nothing less..

By specifiying CP_ACP I assumed that's exactly what you get - why not?

CString   strUnicode = _T("A unicode string");
   char*     szAscii = new char[strUnicode.GetLength() + 1];

   WideCharToMultiByte(CP_ACP, 0, strUnicode, -1, szAscii, strUnicode.GetLength() + 1, NULL, NULL);

OK.. Wait a second.. I will try it out. I just thought that the multibyte character sets was wider than 8-bit..
