VBA:
Sub Example_OLELaunch() ' This example reads and modifies the preference value that controls ' whether to launch the parent application when plotting OLE objects. ' When finished, this example resets the preference value back to ' its original value. Dim ACADPref As AcadDatabasePreferences Dim originalValue As Variant, newValue As Variant ' Get the user preferences object Set ACADPref = ThisDrawing.preferences ' Read and display the original value originalValue = ACADPref.OLELaunch MsgBox "The OLELaunch preference is set to: " & originalValue ' Modify the OLELaunch preference by toggling the value ACADPref.OLELaunch = Not (ACADPref.OLELaunch) newValue = ACADPref.OLELaunch MsgBox "The OLELaunch preference has been set to: " & newValue ' Reset the preference back to its original value ' ' * Note: Comment out this last section to leave the change to ' this preference in effect ACADPref.OLELaunch = originalValue MsgBox "The OLELaunch preference was reset back to: " & originalValue End Sub
