Hi,

Does anyone ehere knows how to disable keyboards keys (e.g. delete key, enter key, spacebar key) once autocad load.

Thanks and regards,

I think I found the solutions to do this by implementing

ObjectOverrule

could you post your key code showing how to realize this?

Here is the code I got from reading an article from dev blog but I forgot the link.

Public Class CErase
        Inherits ObjectOverrule
        Public Overrides Sub [Erase](dbObject As DBObject, erasing As Boolean)
            MyBase.[Erase](dbObject, erasing)
            Throw New Autodesk.AutoCAD.Runtime.Exception(ErrorStatus.NotApplicable, "Use DrawingTool Delete command to delete Spaces.")
        End Sub
    End Class

    Shared objEraseOverRule As EraseOverrule = Nothing

    Public Shared Sub PreventErase()
        Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
        If objEraseOverRule Is Nothing Then
            objEraseOverRule = New EraseOverrule()

            ObjectOverrule.AddOverrule(RXObject.GetClass(GetType(Entity)), objEraseOverRule, False)
            ObjectOverrule.Overruling = True
        Else
            ObjectOverrule.RemoveOverrule(RXObject.GetClass(GetType(Entity)), objEraseOverRule)
            objEraseOverRule.Dispose()
            objEraseOverRule = Nothing
        End If
    End Sub
