Capturing mouse clicks outside VB Application

Hi

Is there a way to know, which application recieved Last Mouse click outside
our VB application.

I am writing an application where I need to know which application is target
of drag-and-drop. Its tedious to get the target of drop from OLE interfaces,
but I think if we can know which application recieved last mouse click message,
we will be able to know which application is target of drop.

Please Help
