VCCLCompilerTool.PreprocessorDefinitions Property
Visual Studio 2012
Gets or sets one or more preprocessor defines. PreprocessorDefinitions exposes the functionality of the compiler's /D (Preprocessor Definitions) option, the MIDL compiler's MIDL Property Pages: General option, and the Resource Compiler's Resources Property Pages option.
Assembly: Microsoft.VisualStudio.VCProjectEngine (in Microsoft.VisualStudio.VCProjectEngine.dll)
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 PreprocessorDefinitions property in the integrated development environment (IDE):
' 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
