Thanks, but unfortunately the link you provided is dead. I am aware of how the event listener can be built and so on. That’s not the problem, but how to get handle to the controls which are invisible in designer. And foremost, is the tabs object defined in some of UNO service so it can find possible child controls placed on a tabs object. If I can get the handle to these controls I can use a structure (type) and give them properties and then collect all into an array and so on…
Here’s an example of the codebehind my VBA UserForm.
