How to - string in DLL

**WojTec**

There is another problem - compatibility Ansii/Unicode.
DLL is compiled with D2010, it uses unit with string type.
In API unit I strings declared as AnsiString:

markieren

Delphi-Quellcode:

			S: AnsiString;

S := FuncReturnsString();

StrLCopy(lpBuffer, PAnsiChar(AnsiString(S)), nSize) // second typecast is from old version

If both DLL and app are compiled in Ansii compiler (D7) - it working, if in Unicode (D2010) - also working. Of one compiled in Ansii and second in Unicode, then raises invalid pionter operation exception, but buffers has correct data. I don't understand. What I'm doing wrong?
