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.WarnAsError = True 
 End Sub 
End Module
