TabPanel event TabChanged problem

juanjo

Hello, I’m working with a TabPanel and have created 5 tabs. I’ve now set up a TabChanged event and added this code:
If TabPanelParametres.SelectedTabIndex = 1 Then
MessageBox(‘Hello’)
End If
When I start the programme, I get three or four messages even though I haven’t selected any tab. However, this only happens if I close the programme and leave it closed on that tab; when I launch the programme again, those three or four messages appear. But if I set the TabPanel to a different index that doesn’t correspond to the one where I want the message to appear, then the messages don’t appear. Is this a programming error on my part, or is there a bug? Thank you.

Hi rgb, the proyect is for windows desktop app.
I’ve tried to make a short video, but it’s too large to upload in the end – sorry about that. The message box pops up two or three times from the TabChange() event of the selected tab where I’ve placed the message box code, and this is in the project; I haven’t tested it in production as I’m still at the early stages. I’ll keep looking into what’s happening and if I find the problem I’ll mention it; if I see that it doesn’t happen, please mark my post as resolved. I thought there might be others with the same problem, which is why I posted this message. Thanks for your interest.

Thanks for reporting this. I’ve reproduced the repeated startup events and confirmed it’s a bug. Your code isn’t the cause. I’ve logged it here, including the details and regression tests needed for the fix.
