WFM_Op function

[donald121]

Hi,

I'm using delphi 6 to program application for DAQ 6071E. When I'm using DAQ driver 6.6, the program's working fine, but after I upgrade to driver 6.9.2. My program crashed. I debugged it and found out the problem is cause by WFM_Op. I wonder what has changed between 6.6 and 6.9.2 that will cause the problem? and how to fix it?

Donald;

I couldn't find anything on NI Data Bases that refer to that issue. One thing you can try is to run one of the NI-DAQ shipping examples that uses that function.

To find out what examples use that function, you can go to NI-DAQ example help, and type in the function name in the search field.

Also, go to NI-DAQ on line help, and choose the search by hardware device option, and go to your DAQ device to see if that function is listed there. If it's not, that means the WFM_OP is not supported under that hardware anymore.

Hope this helps.
