Any one able to create 'User Function' programmes out there?

[Befuddled]

I am going to have a stab at solving my filter issue by using user function to update my filter without any user interaction. At this stage I’m only doing a proof of concept exercise so don’t need loads of error trapping etc….

Is there any one out there who is comfortable programming user function?

I need a programme that will update a filter called ‘TEST’

Ideally I need the compiled dll & the source code so that I have got an example of the code.

Cheers,

B
