Re-using Code

[EnemyGateIsDown]

Hi guys,

I have some functions which are common to a number of forms within my project. So i created a new vb file with a class name and put them into it.

I then thought I could just in the other forms just by inheriting it, however when I do that it says that I can only have one inherit statement containing one class?

So how can I access my "common functions" from my various forms?

Any help is as alway greatly appreciated.

Cheers,

Chris

Its ok think i may have asked too soon.. Looks like i can inherit System.Web.UI.Page in my "global functions" class and then inherit that in my forms...

Yes, that's basically called Page Inheritance. Another way (if you are using version 2.0 of the framework) is to use master pages and create a new instance of you class on the master page. Each child page that uses this master page, will have access to the class.

This is also a much easier way of applying the same functionality of page inheritance.

Also, another approach would be to create a utility class for those common functions, and possibly declare the functions as Shared. The advantage is, you can use these functions in UserControls, MasterPages, and other classes, etc, not just in classes that inherit from Page.
