My program is just to find a dif. b/w two variable and i need to store it in datatable permanently.
my code is like this:
"a=
..
..
b=
c=b-a"
now i need to store this variable "c" into data table.
I have already tried
datatable.value("Output",global)=c
it stores the value but after running the Column is empty.
How can i do it? Is there any alternate?

Hai friend

Method one

Add parameter at the runtime and then enter the values. Run time Datatable will only be visible during run time. If you need to view the values present in the datatable then export it to an excelsheet.

Dim i
DataTable.ImportSheet "C:\Documents and Settings\Deepa\Desktop\Add2.xls",1,1

For i=1 to Datatable.GetRowCount
a=DataTable.Value("Num1","Global")
b=DataTable.Value("Num2","Global")
c =cint(a)+cint(b)
e=Datatable.GetSheet ("Global").AddParameter("Sum",c)

Datatable.Export("C:\Add1.xls")

Method two

If you don't need to export the datatable value then you can simply see the run time datatable in this path

Excel- This is the name of the test which I have given

Res 1- I have executed the test once so I am clicking on Res1

Click on Excel folder->Res 1-> Report->Default.xls

In the default.xls you can find run time datatable values here
