Using the AddressOf Keyword
Any code you write to call a function pointer from Visual Basic must be placed in a standard .BAS module — you can't put the code in a class module or attach it to a form. When you call a declared function using the AddressOf keyword, you should be aware of the following conditions:
AddressOf can only be used immediately preceding an argument in an argument list; that argument can be the name of a user-defined sub, function, or property.
The sub, function, or property you call with AddressOf must be in the same project as the related declarations and procedures.
You can only use AddressOf with user-defined subs, functions, or properties — you cannot use it with external functions declared with the Declare statement, or with functions referenced from type libraries.
You can pass a function pointer to an argument that is typed As Any or As Long in a declared Sub, Function, or user-defined type definition.
Note You can create your own call-back function prototypes in DLLs compiled with Visual C++ (or similar tools). To work with AddressOf, your prototype must use the __stdcall calling convention. The default calling convention (_cdecl) will not work with AddressOf.
