How to batch-change the font size of many listbox item names at once?

[Christ0phe]

Are you sure that your code -although compiled- does work? I am personnaly getting the attached error message... (Type mismatch error 1057)

If the control is not a listbox, then you aren't going to be able to cast the reference to a list box.

What you need to do is check the error wire coming out of the more specific class function.  If no error, then proceed.  If there is an error, do nothing.

It looks like the codes is already doing a check to see if the classname matches a list box.  So you should just put the "To More Specific Class" inside the case structure you have now.

Yes, I'm sure 🙂
You can't transform numeric (for example) reference into listbox ref.
You should use class modifier only for correct references. I.e. move this function into case frame.
