A strange behavior of a Boolean variable

[mencoxx]

Ciao,

I run a device monitoring program and noticed that at the turn of midnight, the program would stop, debugging I noticed that the variable 'flag' would change state on its own.

I solved it, I know I had to use the API Sleep function, but still it's really weird.

I attach a test example.

Thanks a lot.
Domenico

Thank you for your example I haven't had a look at it myself but I know there are a few members here who like a challenge and hopefully someone will have a look and see if they can offer some insight into what's affecting the flag.

Would it be anything to do with this?

Timer function (Visual Basic for Applications)

Office VBA reference topic

Plus you have
If Flag = False
Else
Flag = False
End if

Thank you for your interest.
If the Timer function after midnight resets, then the delay is zero but I don't think it affects the variable 'flag'.

Ciao
