David:
The VPF app will be closed after the imaging activated. Each time when a user presses "V" to view an image file the imaging app still open from the previouse call but the VFP APP will be called but the object is nolong there.
I think if I can use the object reference from the first time the object created it will work, otherwise, I don't think there is anything else would help me. Thank you for being so patient with me.
