Here:
procedure TForm2.ADOTable1AfterOpen(
var AutoIncCount : Integer;
begin
ADOTable1.Sort := 'ID DESC' ;
AutoIncCount := ADOTable1.Fieldbyname('Mem
cxTextEdit1.Text := inttostr(AutoIncCount + 1) ;
cxTextEdit2.SetFocus;
end;
procedure TForm2.ADOTable1AfterScrol
begin
wwdblookupcombo1.text := ADOTable1.FieldByName('Mem
StatusBar1.Panels[0].Text := ' All records :' +IntToStr(ADOTable1.record
StatusBar1.Panels[1].Text:
end;
Problem is this:
How do I prevent the program from crashing down if the adotable1 is empty
at runtime??

It does not work right...
The only way it seems to work is :
procedure TForm2.ADOTable1AfterScrol
begin
if not ADOTable1.Bof then
begin ....
Why is it when I delete last record from table
StatusBar1.Panels[1].Text:
statusbar displays -1 ???

use ADOTable1.RecordCount in the events i mean :
procedure TForm2.ADOTable1AfterOpen(
var AutoIncCount : Integer;
begin
if ADOTable1.RecordCount>0 then
begin
ADOTable1.Sort := 'ID DESC' ;
AutoIncCount := ADOTable1.Fieldbyname('Mem
cxTextEdit1.Text := inttostr(AutoIncCount + 1) ;
cxTextEdit2.SetFocus;
end;
end;
procedure TForm2.ADOTable1AfterScrol
begin
if AdoTable1.RecordCount then
begin
wwdblookupcombo1.text := ADOTable1.FieldByName('Mem
StatusBar1.Panels[0].Text := ' All records :' +IntToStr(ADOTable1.record
StatusBar1.Panels[1].Text:
end;
end;
procedure TForm2.ADOTable1AfterScrol
begin
if AdoTable1.RecordCount>0 then
begin
wwdblookupcombo1.text := ADOTable1.FieldByName('Mem
StatusBar1.Panels[0].Text := ' All records :' +IntToStr(ADOTable1.record
StatusBar1.Panels[1].Text:
end;
end;
I think the reason is that because its an empty recordset then there is no current record number so it returns a default '-1', use the code below
procedure TForm2.ADOTable1AfterScrol
begin
if not (ADOTable1.Bof) and (ADOTable1.Eof) then
begin
wwdblookupcombo1.text := ADOTable1.FieldByName('Mem
StatusBar1.Panels[0].Text := ' All records :' +IntToStr(ADOTable1.record
StatusBar1.Panels[1].Text:
end
else
begin
StatusBar1.Panels[0].Text := ' All records : 0';
StatusBar1.Panels[1].Text:
end;
end;
