DAQmxCfgChangeDetectionTiming and VB6

[got]

Hi,

i am trying to do a little program in VB6 with those function  :

DAQmxErrChk DAQmxCreateDIChan(TaskHandle, "Dev1/port0/line0:7", "", DAQmx_Val_ChanPerLine)
DAQmxErrChk DAQmxCfgChangeDetectionTiming(TaskHandle, "Dev1/port0/line0:7", "Dev1/port0/line0:7", DAQmx_Val_AcquisitionType_ContSamps, 1)
DAQmxErrChk DAQmxRegisterSignalEvent(TaskHandle, DAQmx_Val_Signal2_ChangeDetectionEvent, 0, ChangeDetectionCallback, Null)
DAQmxErrChk DAQmxStartTask(TaskHandle)

i have a 6220card.

I got an error with DAQmxCfgChangeDetectionTiming it seems i didn't pass the right parameters but i don't find any example.

Is there somebody that can help me???

Thank you

Olivier

Change detection timing is not supported on M-series devices. Your 6220 is an M-series device.

Reading other posts from NI engineers, I find that the hardware supports it, but DAQmx does not support it on M-series devices. Let's hope they add support soon!
