test if vb.net function is loaded

[kemp77]

Is there a simple way to test and see if a simple dll I created using vb.net 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)

  (func1)

  (func2)

)

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.
