I am having problems interfacing through VB 4.0 16 bit with a 16 bit
DLL which I made with WATCOM C++.  I can call a number of functions in
the DLL, but I get a Windows system crash when I call a particular
function in this DLL.

	It seems that DLL functions which take as parameters either scaler
values or pointers to strings work fine. The problem arises when a DLL
function expects a pointer to an array (i.e. a pointer to a pointer).
How do you make VB's parameter passage conform to this situation of two
levels of indirection?

	Thanks in Advance for you help.
