I'm developing an application called SysCons.. This application receives data from a serial port and stores it in a database and displays it on the screen..
I have already done with the connection part and everything works fine and also I have a sample database attached to see what kind of data I receive.
This application has been programmed in such a way that on start up when the user presses F10 the application loads the most recent 50 rows from the database and displays it on the screen.
The buffer or temp database table which I have created is called as currentTable which stores the data in a buffer before it is being pushed into the database.
The application is not in history mode when it is first initialized. Now I need an help so that when the user does PAGEUP and PAGEDOWN then the data on the screen should be refreshed. The table which I have created to hold the history data in a buffer is called HistoryTable.
I'm attaching my working application if you want to have a look at it... There is no to worry about serial port and all... Just u can run it without the need of any hardware interfaces. Just change the path of the database.
