How to solve the zkemkeeper problem?

I have used zkemkeeper dll to access the attendance record of finger print device.As suggested by sdk, i have used ReadGeneralLogData(MachineNumber) to read the data to memory and GetGeneralLogData(Mach开发者_JAVA技巧ineNo,enrollmentNo,...) to read the data from memory to PC. But i am getting invalid data like it always gives attendance year as 2000 and random enrollment number etc. So, how to solve this problem.Please help me. I am using c# in vs2010.

Thanks Jig for your answer and i solve this problem myself. I have found that the machine which i have used is TFT(determines attendance machine is Finger print machine or not) so before using GetGeneralLogData(MachineNo,enrollmentNo,...) API i have to checked whether it is TFT or not, if it is TFT then i have to use SSR_GetGeneralLogData() instead of another one.
