I am developing a vehicle parking program using VFP5 on Windows98. There two parking computers that are connected using Microsoft Windows Networking. Both computers are Classic Pentium 233MMX on TxPro mainboard with VGA 4MB (shared) and Sound Card onboard. There is only one LPT1 port and one COM1 port on the mainboard.

The first computer is named 'GATE1' and the other one is 'GATE2'.

The computer on GATE1 is connected to an Epson TMU-210B (auto-cutter) thru the serial port and is also connected to an Epson TMU-210PD (manual cutter) thru the parallel port. The serial printer is used for CHECK-IN (entrance gate) and the parallel printer is used for CHECK-OUT (exit gate). The computer on GATE1 (only one computer) is used for both CHECK-IN and CHECK-OUT.

The computer on GATE2 is connected to only one printer that is Epson TMU-210PD thru the parallel port. GATE2 is an EXIT gate only.

The computer on GATE2 seems to work well but the computer on GATE1 often has problem with my application showing the error message "Resource Manager Internal Consistency Error" and quit immediately.

I create two Report Forms: check_in.FRX and check_out.FRX. The parking operator will key in a character 'I' for Check-in or 'O' for Check-out then my program will choose the printer based on the character entered by the operator ('I' or 'O') as follow:

IF m.in_out = 'I'
SET PRINTER TO NAME come_in1
REPORT FORM check_in TO PRINTER
ELSE
SET PRINTER TO NAME exit1
REPORT FORM check_out TO PRINTER
ENDIF
SET PRINTER TO DEFAULT

and just for your information, before creating report check_in.frx I set the default printer to come_in1 and before creating report check_out.frx I set the default printer to exit1.

Please anyone help me find out the problem of my program and Thank you very much for your help or suggestion.

Should I use two separate computers for handling check-in and check-out?

Best Regards,
