BeginFileDrop Example

Using Programming Languages other than VBA

Public WithEvents ACADApp As AcadApplication	' Use with Application Event Examples
Sub Example_AcadApplication_Events()
	' This example intializes the public variable (ACADApp) which will be used
	' to intercept AcadApplication Events
	'
	' The VBA WithEvents statement makes it possible to intercept an generic object
	' with the events associated with that object.
	'
	' Before you will be able to trigger any of the AcadApplication events,
	' you will first need to run this procedure.

	' We could get the application from the ThisDocument object, but that would
	' require having a drawing open, so we grab it from the system.
	Set ACADApp = GetObject(, "AutoCAD.Application.16")
End Sub

Private Sub ACADApp_BeginFileDrop(ByVal FileName As String, Cancel As Boolean)
	' This example intercepts an Application BeginFileDrop event.
	'
	' This event is triggered when a drawing file is dragged into AutoCAD.
	'
	' To trigger this example event:
	'	 1) Make sure to run the example that initializes
	'	 the public variable (named ACADApp) linked to this event.
	'
	'	 2) Drag an AutoCAD drawing file into the AutoCAD application from either
	'	 the Windows Desktop or Windows Explorer

	' Use the "Cancel" variable to stop the loading of the dragged file, and the "FileName"
	' variable to notifiy the user which file is about to be dragged in.
	If MsgBox("AutoCAD is about to load " & FileName & vbCrLf & "Do you want to continue loading this file?", vbYesNoCancel + vbQuestion) <> vbYes Then
		Cancel = True
	End If
End Sub
