Error - 200089

[Kyle W]

Hi, I've got a program that generates a voltage (post amplifed etc. to drive a motor) and also takes readings from a tachomter and an LVDT. As soon as I run the program I get error - 200089 telling me the task name conflicts with an existing name. If anyone has had this problem before and knows how to fix it I would be interested to hear how.

You don't say if you are using DAQmx but, after the first call to DAQmcCreateTask(...), if you don't call DAQmxClearTask(...) before a new call to DAQmcCreateTask(...) with the same taskHandle, you'll get this error, presumably because the task already exists. I've tested this in Windows XP but not Windows 2000. A somewhat similar error can occur with pointers to graphic objects in XP needing to be re-initialized to 0 that isn't isn't a problem in 2000.

Im using DAQmx Base for the USB - 6009. My program is based on one of the examples supplied.

I'd like to help, could you answer a few questions:
1) What programming language are you using? CVI/LabWindows, LabVIEW, C++, etc.
2) Does the shipping example work w/o modification?
3) Have you created any tasks in the DAQmx Base Task Configuration Utility?
4) Also, are you in Windows?
