run program digital output is one all the time and stop program then digital output is zero all t he time using PCI-6251 with NI-DAQmx

[source codes]

hi every body,
 
i used ur example "C:\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Generate Values\Write Dig Chan.dsp" to get the above application.
Running the program, i can get all one setting all bits to 1, but after stopped the program all output samples still 1 in the oscilloscope.
Pls let me know how can i do that as soon as possible coz the project time line for me is very tight.
 
thanks and best regards

You need to write a logic 0 to the bits prior to exiting you program.
