Yes, these are safe to use in loops, and will not cause Stack Overflow Exceptions. :-) Also, note that one can always trust the good old WideCharToMultiByte, and MultiByteToWideChar functions, and that CComBSTR can construct a BSTR from Regular Character Strings, and Wide Character Strings both. Enjoy Converting. :-) Best Regards, Siddhartha PS: Coincidentally, I have a FAQ on this topic as well, a link to which I’ve provided above. __________ Siddhartha Rao Microsoft MVP - Visual C++ Codeguru Moderator Hi Simon,
