Hi!

COM object usually works in its own memory space, and it is a separate module. For OS sequrity reasons COM object cannot access and know the variables from the main application.

You can only pass a value of the public variable as a parameter to COM object. If you have a lot of values in public variables, put them all into the array and pass an array to COM object.

HTH.
