I need help in developing an application that sits in the system tray (on Windows XP) and waits for a "Hot key" (CTRL-ALT-U for example, it dosn't need to be changable).
When a user presses CTRL-ALT-U the program will send serial commands stx/etx to a serial device, RFID Reader, (here som settings are needed, like COM-port and baudrate).
The program will get a bunch of data back which consists of RFID information from 1 or many tags.
This data need to be temporarily stored (buffered) and parts of it need to be sent (wedged) as keyboard input to the window that was previously on top.
After data from one tag has been "wedged" the program should pop up a very simple window displaying the data (actually a barcode) and ask if alarm wants to be activated or deactivated.
Arrow RIGHT should deactivate (send a serial command with a, settable, hex value ) and Arrow LEFT should activate the alarm (another hex value). After the activation or deactivation and a timer (can be hard coded) the deivce needs to be asked about the status of the alarm and repeat the step a maximum of three times if the alarm status is wrong.
After this the program should (read the serial data again, and discard any that is already processed during this session) give focus back to the window that was previously on top and wedge a new set of data as keyboard input.
If it is easy to implement it would be nice to have the program respond to the hot-key only if a settable window is on top (f.ex. Window title containing Mozilla Firefox) this is not essential though.
I want to own the source code.
