VB Loop through problem

I have a structure (in a module for use between multiple forms):

Code:

Module Module1
    Public Structure walls
        Dim length As Integer
        Dim width As Integer
        Dim wallpaper As String
    End Structure

    Public myWalls As walls
    Public colWalls As New Collection

End Module

This is an assignment - so not looking for a direct answer but an idea on what i should be doing.

only information that is needed across forms is put in the structure. The assignment requires a calculator to work out cost of the quote, how much of each material needs using, the area etc etc..


one of the outputs required is having a datagridview that outputs various info about the quotes. The info held in the dgv is changed on selecting different options. I've done all but one of the options it's only a small part of the mark, but i don't want to hand in an incomplete program :

so i need to look through for wallpaper type say er "embossed" add together the lengths and add together the widths. Multiply the total length by total width and have that output as say wallpaper type: embossed, total area: 5362.


will i need to use "for each"?

I cant see how to do it.

 

FOR EACH Loop usually using when you are in a situation to execute every single element or item in a group

This is the syntax of for..each loop

For Each [Item] In [Group]
[loopBody]
Next [Item]
