There is an important note to run the demo programs. Copy all the files in the Driver to the demo,before compiling or run the demo. For example if want to run a VB demo, please copy all the files in the \DCON_DLL\Driver\Vb5\ to the folder of that demo, or the demo program can not run,and will show error message. All the nessary including files are list below : \DCON_DLL\Driver\BCB3\ i7000.h i8000.h i87000.h uart.h I7000.dll Uart.dll i7000bc.lib uartbc.lib \DCON_DLL\Driver\Delphi3\ I7000.dll Uart.dll I7000.PAS I7000u.pas I8000.PAS I87000.PAS \DCON_DLL\Driver\Vb5\ I7000.dll Uart.dll i7000.bas \DCON_DLL\Driver\VC5\ i7000.h i8000.h i87000.h uart.h I7000.dll Uart.dll I7000.lib Uart.lib
