How come codes work in DAQ driver 6.6, but not work in 6.9.2?

Hi,

I'm using dephi 6 to program my application. My program only work when use DAQ driver 6.6, but not in 6.9.2. I'm using a pair of PCI-6071E daq card. I'm using the dll instead of the ActiveX controls. Could you check my code, see if I did anything work?

Thank you

Hello;

The best way to double check where the problem of your code is, is to put breakpoints on each NI-DAQ call and figure which function is giving you the error.

Then, you can go to the NI-DAQ on line help and double check if that function that is giving you the error is still supported by that version of the driver.

Hope this helps.

Thank you Filipe,

I already tired to put breakpoints on each NI-DAQ call, but the problem is, it breaks on different place everytimes and each time it breaks, it will reboot the computer. It is very tough to debug. Well, I wonder is there an document that shows what has removed on version? I found documents show what has added, but not removed. Thank you.
