The following example modifies the ForcedUsingFiles 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.ForcedIncludeFiles = "myfile.dll"
    End Sub
