It all started with me wondering if i created windows and gadgets all using #pb_any and the user working for several days opening and closing windows if it would be unlimited.

I created a code that opens and closes the same window for 500 times and i receive 0 from the gadget creation at some point.

Is it a limitation, of what? Or am i doing something wrong?

PS: this is a simplified version of the final code with the minimal parts for execution.

thanks,

I would always assume that everything has a maximum value, even if the maximum values can be very large.
Just some thoughts about this.... (You don't have to agree with me)
There is a reason why there are return values that also represent an error case.
When dealing with dynamic objects, you have to pay particular attention to resource consumption. (You learned this when programming under Win16, where pens and brushes ran out faster than you could blink.)
Use a tool (e.g., Task Manager) to monitor consumption.
The longer the program runs continuously, the more important this becomes.

Thanks for the answer, Axolotl, i'll keep that in mind

I found out that the issue was due to the fact that i was doing it inside a for and it wasn't processing the closewindow events, therefore, the windows were not being closed.

Once i closed the window, i was able to recreate the window as many times as needed.

also all your '.q' type is wrong, it should be '.i' (or better, nothing as specified in the doc)

Posted: **Wed Sep 03, 2025 6:54 pm**

Thanks, Fred, i'll fix that too.

maybe you explain what is your goal.
Your code looks complicated and it is not the best for debugging.
I'm sure there are more clear solutions for your problem.
