Is there a simple way to test and see if a simple dll I created using is loaded in the current drawing?


The following obviously wont work, but this is the basic structure of what I have in mind...

(if (not vba-routines.dlll)

If the DLL is defining LSP functions, you can test for the presence of function "myLSPFunction" as (if myLSPFunction (progn (blah)...)).  If not, you could add a simple information LSP function to the DLL to accomplish the same thing while returning a version number or some other useful information.

If you are going to fly by the seat of your pants, expect friction burns.

A good question will be halfway to a good answer.
