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.

I am confused.
Is the TDataset parameter actually the TTable or a different object that
just happens to have the same name?
By ??.Name do you mean the component Name or the actual table name in
the database.?
If the TTable and the TDataset are actually the same object then just go
"if MyTable = MyDataset then begin"

Sorry Traci
Didn't make myself clear
I want to test if a TTable with the same name as the
parameter TDataset is active.
If it is not I want to Open the TTable that has the same name
as TDataset.
