VCMidlTool.StructMemberAlignment Property

Gets or sets 1-, 2-, 4-, 8-, or 16-byte boundaries for struct member alignment.

Namespace:  Microsoft.VisualStudio.VCProjectEngine
Assembly:  Microsoft.VisualStudio.VCProjectEngine (in Microsoft.VisualStudio.VCProjectEngine.dll)

midlStructMemberAlignOption StructMemberAlignment { get; set; }

StructMemberAlignment exposes the functionality of the C++ compiler's /Zp (Struct Member Alignment) option, and the MIDL compiler's MIDL Property Pages: Advanced option.

Use the structMemberAlignOption enumeration to change the value of the VCCLCompilerTool property.

Use midlStructMemberAlignOption to change the value of the VCMidlTool property.

The MIDL tool does not allow 16-byte boundaries.

See How to: Compile Example Code for Project Model Extensibility for information about how to compile and run this example.

The following example modifies the compiler's StructMemberAlignment property in the integrated development environment (IDE):

[Visual Basic]

' add reference to Microsoft.VisualStudio.VCProjectEngine
Imports EnvDTE
Imports Microsoft.VisualStudio.VCProjectEngine

Public Module Module1
    Sub Test()
        Dim prj As VCProject
        Dim cfgs, tools As IVCCollection
        Dim cfg As VCConfiguration
        Dim tool As VCCLCompilerTool
        prj = DTE.Solution.Projects.Item(1).Object
        cfgs = prj.Configurations
        cfg = cfgs.Item(1)
        tool = cfg.Tools("VCCLCompilerTool")
        tool.StructMemberAlignment = structMemberAlignOption.alignSixteenBytes
    End Sub
End Module
