Passing keypress messages to other applications

[Newendorp Bruce C]

I am using MetaCard with an external dll to monitor the status of the inputs of a National Instruments data acquisition card.  Normally I use these inputs to connect physical prototype controls to the MetaCard simulations of display screens I create.  A different group in our organization has started using Flash as a simulation tool however they do not have an easy way to connect the physical controls.  (I suggested they start using MetaCard but they wanted to continue with the known path...) The Flash simulation can react to keypresses so I would like to create a MetaCard application that gets the physical control inputs through the data acquisition card, converts the control inputs to keyboard messages and then passes them to the Flash simulation which will be running in the active window.

Anyone know how to do this in the Windows 2000 environment?
