Hello can someone help me out how to create this feature:
My.Settings.Time = 10 ( time integer user 10)

And i want when form load Timer1 is starting and reading from My.Settings.Time value
And to start countdown from that value to 0. When value become 0 to show msgbox(work).

Thats what i'm trying to do. To read from My.Settings the value and countdown from it.

What I have tried:


            Timer1.Interval = My.Settings.Time
            If My.Settings.Time = 0 Then
            End If
        Catch ex As Exception
        End Try

Debug the code and find a specific issue you need help with.

it doesnt countdown the value from settings
ZurdoDev 24-Sep-20 14:07pm
I don't see any code that will countdown. Maybe you mean the timer does not fire?

If you want to countdown in each tick event, create a variable that stores the number 10 and then in the tick event just subtract one from it.

something like:
Dim progress As Integer = My.Settings.isBackUpTime
Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick
progress = progress - 1
'Timer2.Interval = 1

If progress = 0 Then
MsgBox("start copy")
End If
Catch ex As Exception
End Try
End Sub

It is still not clear exactly what you want to have happen, but yes, something like that.

it is clear.
First get the number from my.settings.time
Then timer tick each second reduce progress - 1 until gets 0 then when its 0 show msgbox

Good. I'll post that as a solution.

You have no choice but to learn to use the debugger. It's going to tell you what the values are at any point in your code while it's running.

Set a breakpoint on the If statement, run the code, and then the breakpoint is hit, the code will stop running and show you the line that's going to execute next. Hove the mouse over the Time part of My.Settings.Time and it should show you the current value. If that value is not what you expect, you're going to have to dig into why.
As mentioned in the comments, declare a class level variable and then in your timer tick event subtract one from that variable and then do your if statement to check the value.
