Modified Event
« on: December 14, 2015, 02:47:54 PM »
Hello guys, I copied this code from the autocad help,
but a want to create an event of the an object with handle,
a event that is independent of others sub, that can be used when the autocad is started or anytime
I want to create a database that has some handle, and that when I change a especific object, too change the database, a dynamic database
sorry for my english, it is not very good..  :-D

Code From Autocad Help:
Code: [Select]
Public WithEvents PLine As AcadLWPolyline    ' Use with Modified Event Example
Sub Example_Modified()
     ' This example creates a lightweight polyline in model space and
     ' references the PolyLine using the public variable (PLine) which
     ' is set up to intercept Modified events.
     ' This example then modifies the new object, triggering the code
     ' in the Modified event.
    Dim points(0 To 9) As Double
    ' Define the 2D polyline points
    points(0) = 1: points(1) = 1
    points(2) = 1: points(3) = 2
    points(4) = 2: points(5) = 2
    points(6) = 3: points(7) = 2
    points(8) = 4: points(9) = 4
    ' Create a lightweight Polyline object in model space
    ' * Note: We are returning the new PolyLine object into a Module
    ' level variable.  This allows us to intercept events associated
    ' with that particular object.
    Set PLine = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
    ' Modify object to trigger event.
    ' * Note: The event code for the PolyLine modification will be triggered
    ' before we move forward and refresh the view, so the line will not
    ' appear blue when the event message box is displayed.
    Dim color As AcadAcCmColor
    Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.20")
    Call color.SetRGB(80, 100, 244)
    PLine.TrueColor = color

    ThisDrawing.Regen acAllViewports
End Sub

Private Sub PLine_Modified(ByVal pObject As AutoCAD.IAcadObject)
    ' This example intercepts an object's Modified event.
    ' This event is triggered when an object supporting this event is modified.
    ' To trigger this code: Modify an object connected to this event
    ' * Note: By connected, we mean the object set up to intercept events using
    ' the VBA WithEvents statement

    ' Use the "pObject" variable to determine which object was modified
    MsgBox "You just modified an object with an ID of: " & pObject.ObjectID
End Sub
