I want to set current row in query before form opens in dependence on given Id as following:
01  Query.Open;
02  while (not Query.EOF) and
03    (Id  Query.Fields [0].asInteger) do
04      Query.Next;
05  ShowModal;
and get error message bout access violation at address ...
When I remove lines 02-04 its ok but not exactly what i meant :)

Deng,

If you have the ShowModal statement in a FormCreate event it can cause an access violation. Try this instead in the CALLING form:

Application.CreateForm(TFormName, FormName);
FormName.ShowModal;

The code will execute (when created) then return to the caller which will in turn do a ShowModal on the form.

Good luck with your project!
