To Hide columns at runtime ( dynamic) Powerbuilder 7

PB 7

I alwasy call all reporting datawindows in datawindow control [dw_1] in a window W_resp_criteria_report
The datawindow object is set at runtime and the reporting till the end is quite sucessfully running.

Now,
1) I will always call grid datawindow.
2) I want to hide some columns of the reporting datawindow at runtime (dynamically)

Lets suppose I have a datawindow rdw_salary with columns (emp_name,gross_salary,inc_tax,adv,discount,loan,nic_no,ntn_no)
Sometimes I need not to show column nic_no
Sometimes I need not to show column ntn_no
Sometimes I need not to show column nic_no and column ntn_no.

The columns which are not to be shown, I will assign in array variables

hide_column[1] = nic_no
hide_column[2] = ntn_no


If the array hide_column[] is empty then ok elseif
hide_column[1] = nic_no
then  I would like to hide the columns nic_no from the report rdw_salary
or if
hide_column[1] = nic_no
hide_column[2] = ntn_no
then  I would like to hide the columns nic_no,ntn_no from the report rdw_salary

I have some idea but very week in commands like dw_1.modify, dw_1.column.width=0 etc.
Please somebody help.

Mateen
