hi,
I have a table called "userdata" which contains (username, password)
I have a window in Delphi with two edit fields username and password and one button "Login"
After typing username and password, when I click on "Login" button, I would like to check whether username and password is match or not
I have tried with following code but it is not working
Code:
procedure TForm1.Checkuserdata(Sender: TObject);
begin
Table.Open;
Table.First;
while not Table.Eof do begin
if (Edit1.Text = Table.FieldByName('username').AsString) and
(Edit2.Text = Table.FieldByName('password').AsString)
then
Showmessage('match the user data');
exit;
end;
