Interesting... this is the code which makes the panel visible

PnlViewAdmin.Visible := True;
with dmLocalStore do begin
if not IB_QStockCodes.Active then begin
IB_QProjOffsEdit.Open;
IB_QStockCodes.Open;
IB_QStoneGroupLookup.Open;
IB_QStoneDescLookup.Open;
IB_QStockTypeLookup.Open;
IB_QWareHouse.Open;
IB_QArea.Open;
with dmLocalStore do begin
IB_QStockCodes.DisableControls;
IB_QStockCodes.Bookmark := qbmStockType;
IB_QStockCodes.EnableControls;
end;
end;
end;
irLastPanelView := 1;
ActiveControl := IB_Grid1;

The panel is set to visible, then the queries are opened... The query in
question here is IB_QWarehouse... If I move it up the list and open it in
number 3 position (instead of number 6), there is no error. I think it must
be asynchrony in the drawing of the grid starting before the queries are
opened. I shall move them up to before I set the panel visible. If the
number of queries had been fewer, it may never have shown up as an error
until perhaps I got a 2GHz CPU machine...

thanks for your help

This is Delphi stuff isn't it - AsBoolean will return
true/false not a character?
So
if (BufferFieldByName('myboolfield').AsBoolean) then

Historic compatibility ( I think <g> )
