help with initial

[lwong]

the code like

Private Sub Form_Load()
Dim num As Integer
num = 3
End Sub

when I use watch to view the value of num, it show the value is 0, why?

[Sahir]

after num = 3 it will contain 3

Normally it is, but when I use quick watch to view, it show the value is 0. this is why I wondering

[GremlinSA]

Private Sub Form_Load()
Dim num As Integer
num = 3
End Sub

basicaly you've defined num and a local variable to be used only with in the sub Form_Load. Any reference to it from any other sub will return null..

To use num is a number of subs rather use

private num As Integer
 
Private Sub Form_Load()
num = 3
End Sub

hope this helps..
