How do you TRACE() a BSTR??

[Anders Gustafsson]

Where Name is a BSTR: TRACE("\nFIELD[%d]: %s",j,(LPCTSTR)Name); or TRACE("\nFIELD[%d]: %s",j,Name); Both just print the first char?? Anders G

i think this will do it: TRACE("%S", myBeaster);

It did! Thanks!! This basic stuff is slowly polluting our pure C++ world ;)

a BSTR is a UTF-16 (or is it UCS2? can't remember) encoded string. This means that each character is a 2 byte word. The ASCII character set fits within a single byte of each word. As such, from a char* point of view, a BSTR is basically a string with a \0 character between every character. Hence you get only the first character.

%S will work as long as you are calling an ANSI trace function. %S means "a string in the character set opposite of the current TCHAR character set". To make it work in all cases, use %ls instead.

TRACE("\nFIELD[%d]: %s",j,(LPCTSTR)_bstr_t(Name));
