Is modified code retained on subsequent changes?

Hi, Just wondering...

I've been reading the forums and quite a few answers require custom code to be inserted or replace existing code in the generated pages to make the output do something 'special'...

If I was to make a change like this eg: 'Position to near current date in a list' question...

Andreas,
you can do the following:

1. check off No records on the first page option on the Edit SQl query tab.
   
2. build your pages.
   
3. open generated ..._list.php file, find these lines:
   QUOTE
   if(!count($_GET) && !count($_POST))
   
   $strSQL = AddWhere($strSQL,"1=0");
   and replace it with this one:
   QUOTE
   if(!count($_GET) && !count($_POST))
   
   $strSQL = AddWhere($strSQL,"`FieldName`>now()");
   where FieldName is your actual field name.
   
   To recieve all records click on the Show all button on the LIST page.
   would PHPRunner respect these changes if I was to later-on open the project and mess around some more in the wizards or would it write back the original list.php file? and mods be lost..?
   
   Just wondering up front..
   
   thanks
