>I'm writing a simple COM object in VC++ 5.0 that will be used in VFP 5.0. The control has a single interface that has four basic functions. One returns a string, one returns an int, on returns a float, and one returns a BOOL. In VB, all four functions seem to work fine. In VFP, all work fine except the method that returns a BOOL. VFP gets a 0 or a 1 from it, not a .t. or .f. (it gets an integer, not a logical).

The standard BOOL return from C++ is a SHORT; if you wrap the result in an IIF(), you'll get what you want:
lMyResult = IIF(MyDLLFunctionCall() = 0, .F., .T.)
