Not entirly correct

(SQLTCHAR FAR *)"DSN=test;"

when UNICODE is defined, will create a SQLWCHAR * pointer, but the thing it points to will still be a char string;

I think thats the problem, you are passing the address 8bit string into a function thats expecting a 16bit sequence of values. Casting the pointer to a pointer of another type will not alter the thing thats being pointed to.

Remember C will do what you tell it to, even if thats not what you want it to do :-)
