Good morning everyone,
I have a report to make in reference to the user object.
By creating the treeview object with the image array that composes it. By calling the function: SetOverlayPicture(declaration index, array image index) it is not possible to declare more than 15 elements.
If the 16th element is declared, the function returns value -1.
Is there any solution how I can use more than 15 items?

Hi Davide;

  I just tested this OK with over 30 images assigned in the TV control.

  What version & build of PB are you using?

Regards ... Chris

OK .. I was now able to recreate your maximum Overlay issue of up to 16 images. After that, the PB 2021 runtime will not accept any more.

Even though I had 50 Picture & 50 state images in the Tree-view. So it seems that the overlay limit is not dependent on those other array elements.

FYI: The same 16 overlay image restriction is also there in PB 2022.

Please open a Support Ticket for this issue. There are probably two issues: A) Missing limitation limit in the documentation and B) the 16 overlay image limitation (maybe Appeon needs to increase this old PowerSoft restriction).
