RE: opening, modifying, and saving an existing xls workbook in rpg

The file is in the ifs so opening and reading it will not be a problem.

If you are needing to read the Windows directory on the PC (as opposed to
getting to it via /QNTC), then this little bit of VB code will do it for you
and output the results to a text file.

This is VB6 code...probably an easier (i.e. less code) way to do it with
.NET but I've not needed to do this for a long time so I've never rewrote it
in .NET.

Someone else (Vern maybe) could probably show you the .Net version of this.

Can someone point me to any examples of opening, modifying, and saving an
existing xls workbook. I would want to:



Open the workbook

Open a sheet

Remove existing rows from a certain point on

Add new rows from certain point on

Save sheet

Open next sheet and repeat





I have been working with Scott K HSSF stuff, but have only been creating new
workbooks, not updating existing.



Thanks
