WRITEDATAQFILE Active X Control

Description:

General errors from the Active X control, as follows:

250:      File path is too long

If Windows generates an error, this event returns that error to your program.

If you continue to receive a control error and absolutely cannot determine the problem add the line "debug = 2" to the [Global] section of C:\Windows\tpdataq.ini and try running your program again. You will see a Windows message box showing API functions and operations being used. Using this method, customer service can better understand your problem. Be sure to remove the line once the problem is resolved.
