Simple timer problem

I want to start a timer when a command button is pressed on one form and
i want to stop timing when a command button is pressed on another form. How can
this be done. How does the other form know there is a timer running?

On First Form

private Sub Command1_Click()
'Turn timer on
Timer1.Enabled = true
End Sub





On Second Form

private Sub Command2_Click()
If Form1.Timer1.Enabled = true then
'Timer is running
Form1.Timer1.Enabled = false
else
'Timer is not running
End If
End Sub




Alternate for Second Form
(Turn it off without checking it)


private Sub Command3_Click()
'Ensure timer is turned off
Form1.Timer1.Enabled = false
End Sub

Thanks. That works, but i heard it was bad programming practice to do it that way although i can't see a way round it!
