下面的示例在 PreprocessorDefinitions 集成开发环境 (IDE) 中修改编译器的属性:

' 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  
        Dim oldDefs As String  
        prj = DTE.Solution.Projects.Item(1).Object  
        cfgs = prj.Configurations  
        cfg = cfgs.Item(1)  
        tool = cfg.Tools("VCCLCompilerTool")  
        oldDefs = tool.PreprocessorDefinitions  
        tool.PreprocessorDefinitions = "_TEST;" + oldDefs  
        MsgBox(tool.PreprocessorDefinitions)  
    End Sub  
End Module
