VBA calling DLL function: how can I make it re-entry?

[dan guo]

Hi
I created a DLL which contains two DLL functions in VC++.
The first DLL function has defined a global variable,
which is a handle of an object. This object is created
when the first DLL fuction is called.

The second DLL function wants to access the global object
created by the first DLL function.

However, when I call the 2nd DLL function in Excel/VBA,
it somehow created a totally seprate instance which does
not find the global object created by the 1st DLL
function.

How can I fix this problem?

Thank you,
Dan
