Namespace: Microsoft.VisualStudio.VCProjectEngine
Assembly: Microsoft.VisualStudio.VCProjectEngine (in microsoft.visualstudio.vcprojectengine.dll)

Property WarningLevel As warningLevelOption
Dim instance As VCCLCompilerTool
Dim value As warningLevelOption

value = instance.WarningLevel

instance.WarningLevel = value
/** @property */
warningLevelOption get_WarningLevel ()

/** @property */
void set_WarningLevel (/** @attribute InAttribute() */ warningLevelOption optSetting)

function get WarningLevel () : warningLevelOption

See Examples for Project Model Extensibility for information about how to compile and run this example.

The following example modifies the compiler's WarningLevel 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.WarningLevel = warningLevelOption.warningLevel_0
    End Sub
