When we want to pass a value from one form to another form.

1. We may pass to a label of another form
2. Declare a global variable and assign a value to variable.
3. Pass a value to global property.
4. Pass through a global function

I confused against global variable and global property.

What different between this two. Why we want to use property instead of public variable ?

[Hack]

This is an example of a global property

Public Property Get Test() As String
    Test = sValue
End Property

Public Property Let Test(ByVal vNewValue As String)
    sValue = vNewValue
End Property

This is an example of a global variable

Public Test As String

Thanks Hack,

I know the coding method. Just wondered in what of the condition i have to use property and in what of the condition i need to use public.

A Public variable is just a variable. A Public Property can be used as a variable but it can also contain code. For example

Public Property Let Test(ByVal vNewValue As String)
    If Len(vNewValue) < 10 Then
        Test = vNewValue
    Else
        Msgbox "Too long"
    End If
End Property

the property is also a part of the object in which it's created. In this case, a form. And multiple instances of the same form can have different values. A global variable can only have one value.
