Examples

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 WarnAsError 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  
        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
