How to pass event between two applications?
How to use events to trigger reading of a shared memory buffer?
I have a windows application that I need to notify when a finger scanner detects a known finger template. The finger scanner interface runs as a Java application in the background and is launched by the windows application, written in the development tool WinDev from PC Soft in France.
I am new to Java development and have studied the event processing. However, I am not sure how to set up an event source that is not tied to a GUI object. I don't know what type of event to use or if another application can be the "listener".
I have two Java applications using shared memory but they have to use a thread wait loop to look for changes. I would prefer to use events to notify the action application to read the buffer.
Any suggestions on where to go next would be appreciated.
