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
