Hi Alexandre,
Thanks for that. Your client is running 9 year old versions of the software, so it's likely their version of GridView may not support all the features I've mentioned.
You can control whether an XLS or CSV file is created by changing settings in \Softrak\System\SSI2XL.INI. Details can be found in
this PDF on our web site.
Sorry, but from this point on you're going to be on your own. This forum is can be read by all, but only clients on a current Upgrades Plan can use it for Technical Support. Perhaps you can encourage your client to make move to current versions of their modules if only so you can continue to receive help here.
