I’ve found a bug that I can replicate which I wanted to point out to you.
Open a new project and create a second Form. Drag a BS button (it may happen with other buttons but I’ve only tested BootStrap) onto the first form and set the ChangeForm property to point to the second form. I then ran the app in my desktop browser just to make sure it worked, but I can’t imagine that affecting anything.
Now select the second form and change it’s ID (I changed it to fmTest). If you go back to the button on the first form you’ll notice that the ChangeForm property is blank. I don’t know if it’s supposed to have also changed to reflect the new ID of the second form, but blank is also fine.
However, I discovered the problem because I didn’t touch the ChangeForm property again and instead set an onclickevent to do something else, but nothing happened. For this test set an onclick event to simply display a MsgBox with ‘Test’ or whatever when the button is clicked on and you’ll find it doesn’t work when you run it in your browser. It drove me nuts because the button simply refused to work no matter what I did and the worst thing was that no error was reported.
Hope this was useful.
Whilst I’m here, are all the errors shown in the screenshot normal?
