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

No, we cannot extend an enum in Java. Java enums can extend java. lang. Enum class implicitly, so enum types cannot extend another class.
Enums are not supported in JavaScript natively. We can however create Enums using Object. freeze by creating objects containing all the enumerable properties and then freezing the object so that no new enum can be added to it.
Enums are one of the few features TypeScript has which is not a type-level extension of JavaScript. Enums allow a developer to define a set of named constants. Using enums can make it easier to document intent, or create a set of distinct cases.
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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
