How come the following gives me an access violation? BSTR *s = NULL; *s = SysAllocString(L"string");

Because the variable s points to NULL, and the line

*s = SysAllocString(L"string");

makes the result of SysAllocString() to be stored in the memory position stored in s, and because that position is NULL, it gives you an access violation.

Try doing this:

s = SysAllocString(L"string");

Hi,

I don''t know what SysAllocString does, but try:

BSTR *s = NULL;
s = SysAllocString (L"string");
