that means sometime, they can replace each other, right? like the screenshot, right? Dear Kevin

Microsoft Access

Sometimes they are interchangeable, but not always. It really comes down to the timing of the events shown above on how Access is working.

Thank you, Scott and Alexis, for this informative exchange. I used ONLOAD almost by default but wondered about the nature of the other event.

Thank you, Dear Scott Axton. thank you for your  "Open-Load-Resize-Activate-Current" .  just now, i will watched the On close and On Unload sample video from Techhelp video with " Access Index"
