Functional interface module 10, be connected with the RFID reader, for the functional interface of realizing the RFID reader is provided;
In specific implementation process, between functional interface module 10 and RFID reader, can be connected by RS232 serial ports or network interface.
In specific implementation process, between second development interface 12 and application module 14, can be connected by pipeline.
Application module 14, be connected between functional interface module 10 and second development interface 12, for human-computer interaction interface is provided, and according to the inter-process messages calling function interface module 10 from second development interface 12.
In specific implementation process, after application module 14 receives above-mentioned inter-process messages, calling function interface module 10, functional interface module 10 by and the RFID reader between RS232 serial ports or network interface, indication RFID reader is carried out the operation corresponding with these inter-process messages, and obtain the result of operation, therefore, application module 14 also returns to second development interface 12 for the execution result by calling function interface module 10.
And, do not show human window when moving due to process tray, only on taskbar, show an icon, representation program moves, and when process tray moves in program, its main window is invisible, therefore, can not disturb the runnable interface of foreground program, also can not show unnecessary window.Therefore, in embodiments of the present invention, application module 14 is developed as to process tray, an icon is presented in the static announcement of taskbar right-hand member district, and response user's mouse action.
In specific implementation process, due to dynamic link library file (Dynamic LinkableLibrary, referred to as DLL) can reduce the size of execution (EXE) file and to the demand of memory headroom, and can by a plurality of application programs, be used simultaneously, therefore, functional interface module 10 and second development interface 12 adopt DLL to realize in embodiments of the present invention.
In specific implementation process, can realize above-mentioned process tray by following steps:
One, the main window of concealing program
Make the main window of program invisible, and task button on taskbar, do not occur, accomplish above-mentioned two aspects, style and the expansion style of main frame window need to be set respectively.
Two, the icon of representation program operation is added to taskbar.
Three, realize user and program interaction.
Realize user and program interaction, when the user clicks or double-click left mouse button or right button on this icon, will carry out corresponding operation, at least should respond the intention that the user stops this program.
Four, delete program icon during EOP (end of program)
When EOP (end of program), need to delete the icon in the announcement district, should call the Shell_NotifyIcon function simultaneously.
Five, set up the pipe service device, process pipeline message
Inter-Process Communication (between two processes without set membership) can only be used named pipes, message, socket etc. to carry out communication.Because named pipes has flexibly, do not rely on the advantages such as forms, speed are fast, therefore embodiment of the present invention Inter-Process Communication adopts the mode of named pipes to realize.Particularly, can at first create a named pipes, then wait for the link of other processes, after other process links, first read ducted message, then processing messages.
