Applies to:

DATAQSDK Active X Control

Description:

Fires when a control error is detected by the control. This event fires most commonly as a result of an incorrectly defined DeviceDriver, DeviceID or SampleRate.

If you continue to receive a control error and cannot determine the problem add the line "debug=1" to the [Global] section of C:\Windows\tpdataq.ini and try running your program again (see DataqSDK Log File). When the error occurs, pause Visual Basic to close the DataqSDK.log file and look at the end of it. If necessary post the relevant part of the file in a support forum or email the entire file to support@dataq.com (see Technical Support). Be sure to remove the line once the problem is resolved.
