Examples

The following example modifies the CPreprocessOptions 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 VCMidlTool  
        prj = DTE.Solution.Projects.Item(1).Object  
        cfgs = prj.Configurations  
        cfg = cfgs.Item(1)  
        tool = cfg.Tools("VCMIDLTool")  
        tool.CPreprocessOptions = "test"  
    End Sub  
End Module  

Remarks

CPreprocessOptions exposes the functionality of the /cpp_opt MIDL option.
