Question

Is there a way to combine Enums in VB.net?

Answer 1

I believe what you want is a flag type enum.

You need to add the Flags attribute to the top of the enum, and then you can combine enums with the ‘Or’ keyword.

Like this:

<Flags()> _ Enum CombinationEnums As Integer   HasButton = 1   TitleBar = 2   [ReadOnly] = 4   ETC = 8 End Enum 

Note: The numbers to the right are always twice as big (powers of 2) – this is needed to be able to separate the individual flags that have been set.

Combine the desired flags using the Or keyword:

Dim settings As CombinationEnums settings = CombinationEnums.TitleBar Or CombinationEnums.Readonly 

This sets TitleBar and Readonly into the enum

To check what’s been set:

If (settings And CombinationEnums.TitleBar) = CombinationEnums.TitleBar Then   Window.TitleBar = True End If
