If I define a variable in the class such as
Private DontHardCodeThisValue As String = "This is not hard coded"
Then, in the same class for the shared function, I'll need to create an
instance of the class correct?
Public Shared Function F2(ByVal value2 As String) As String
Dim MyVariable As New Class1
Return MyVariable .DontHardCodeThisValue
End Function
Now, in Form1 I also create an instance of Class1 to have a reference to F2.
Doing this will create two instances of Class1 correct? One in Form1 and
the one created in F2. Is this good practice? How else can it be done?
Thanks,
Brett
