Hi,
Does JADE have built in collections like in Visual Basic where you can access a collection of forms, command buttons or text boxes etc. If so, how do i access them.
Also I want to get an Integer value of the number of Instances a Class has, how can I use that in .... lotTable.rows := [number of instances in class lots];
Also I want to populate the table with data, eg.
Lots has a property 'name'
I want to put the property 'name' in all the rows in column 3, but for each row it has to be for a different instance and the rest of the data on the row has to be from the same instance.
Can and how can this be done?

thanks,
Philip Q

Philip, JADE does have these built in collections under the covers, some of which are exposed to the developer. Form::controls() allows access to form controls
 If iterating through these, then you can test for TextBoxes or Buttons - the online help for this method gives a code snippet that does what you want. (Have a look sometime at the online help for the following system classes - they have many 'under the covers' collections and attributes that can be very useful - Schema, Form, Window, Process, Class, Object, ...)   Instances count - use the Collection::size() method, which returns an integer. You can use the JADE instances collection (which contains all instances of a
 given class), or your own application specific (sorted or filtered) collection e.g.     Lot.instances.size
     global.allLotsByName.size Populating a table - iterate through your collection, calling table.addItem for each row. AddItem() accepts a string, which is the text displayed in the table. Separate each column using a Tab character - the lot name will go into column 3 in the code below. It can also be useful when adding rows to associate the object (lot) with the row (* below)
   foreach lot in allLotsByName do
     table.addItem("" &Tab& "" &Tab& lot.name &Tab& ..... remaining columns
     table.accessRow(table.row).itemObject = lot;  (*) endforeach Note the above is indicative only. There's also lots of other options (and gotchas) for a variety of situations, so read the online help for these and associated calls. Hope this helps,
 Rob

This was deliberately experimental - I wouldn't have tried this a year ago, but maybe today, most readers can handle html? No complaints so far!

I received a message from a user who's newsreader does not support html (and does not want to upgrade), so I suggest submissions are sent in plain text.
