Remarks

The VCCodeUnion object is used to modify an existing union construct.

See How to: Compile Example Code for Visual C++ Code Model Extensibility for information on how to compile and run this sample.

Examples

This example displays the name of each union code element in the current solution. It assumes a C++ project is open and that it has global unions.

Sub GetAllUnions()
    Dim vcCM As VCCodeModel
    Dim vcUnion As VCCodeUnions
    vcCM = DTE.Solution.Item(1).CodeModel
    For Each vcUnion in vcCM.Unions
        MsgBox(vcUnion.DisplayName)
    Next
End Sub
