[DUG] Component names

[Mark Howard]

OK. I'll try to be more clear, by using the ACTUAL code.

I have:
"procedure LoadGrid(grid: TStringGrid; table: TDBISAMDBDataset);"

The parameter "table" is defined as a Dataset because ususally a TTable is passed but occasionally a TQuery is passed.

Before I do stuff, I want to see if the Dataset is active and if not, open it: so I guess I can do

   "if not table.active then
       table.open;

BUT I really want to use another procedure

"OpenOneTable(table)" instead of table.open becuse it does a bunch of error trapping

Trouble is OpenOneTable requires a TTable to be passed to it - not a TDataset
and THAT (finally) is what I need a hand with.

Mark

PS the reason I am doing this is to speed up the opening of my app in Client/Server mode by delaying the opening of tables until they are needed.
