WarnAsError Property

Visual Studio .NET 2003

Enables the compiler to treat all warnings as errors. Exposes the functionality of the C++ compiler's /WX option and the MIDL compiler's /WX option.

[Visual Basic .NET]
Public Property WarnAsError() As Boolean
[Visual Basic 6]
Property Get WarnAsError() As Boolean
Property Let WarnAsError( _
   ByVal NewValue As Boolean _
HRESULT __stdcall get_WarnAsError(
   /* [out, retval] */ VARIANT_BOOL* retVal
HRESULT __stdcall put_WarnAsError(
   /* [in] */ VARIANT_BOOL NewValue
public bool WarnAsError {get; set;}
[JScript .NET]
public function get WarnAsError() : Boolean
public function set WarnAsError(
   NewValue : Boolean


The following sample code modifies the compiler's WarnAsError property in the development environment:

' 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
