Dear All,

I want to know how to transfer pointer of a function (written by VB) for a funtion in a dll (function in dll will call the function written by VB by its pointer). Can anyone of you help me?
Thank a lot.

Oh, hold on. You need the pointer to a function as a callback function. You do that using AddressOf .

AddressOf MyfunctionName
