I am creating a schedule programmatically using C#.

At the time of creating the schedule I am using a template
which has custom added columns.

I want to add values for these custom added columns at the
time of creating schedule.

Pls suggest how this can be achieved?

Regards,
Monica

To make sure you have the most productive way to achieve this I should know
how these values are presented to the program.

By all means, the following works.
Suppose you want to add values to the .Text21 column

You walk through the tasks of the output file

For each anytask in output_file.tasks
if not anytask is nothing then 'skip emty lines
(you here find the relevant value for that task)
anytask.text21= whatevervalueyouhave
end if 'Is nothing
next anytask
