class functions

i've programed classes in C++ where you can have functions that are specific to the class and have access to all the variables in the class.

how would i need to setup a Sub that would have access to these variables?
i want something along the lines of

Private Sub DrawAddOne(ByVal a As Integer)
    m_Draw(a) = m_Draw(a) + 1
End Sub

Hello TheIrishThug,

Unfortunately VBA is not a true object oriented language like C++. A VBA object does not inherit all the properities from a particular class when it is created. Programmers who use other OOLs that start to learn VB or VBA often assume that a Class is a Class. A Class object in VB or VBA is more like Java and nothing like a C or C++ class. I would suggest you read up on VB classes to gain a better understanding of their function and design. Wish I could be more help, but it isn't as simple as your example.

Sincerely,
Leith Ross

Declare the variables as module level variables perhaps? That is, before any
procedure declarations within the module.

Declare the variables in the declarations section of the class
(before and outside of any procedure), and make you procedures
Public not Private. E.g.,


Private m_Draw(1 To Whatever) As Whatever

Public Sub DrawAddOne(ByVal a As Integer)
m_Draw(a) = m_Draw(a) + 1
End Sub
