[Lazarus] TForm.ModalResult := mrOk problem FIXED

[FreeMan]

Thank you for your answer
nearly 5-6 six hours trace all my code line by line, I found problem, 
Problem is in my code.
for ModalResult := MrOk need user & password control then can set, so 
its in procedure, user & password check in my component(I was write 
nearly 7 years ago in delphi) I convert it to lazarus.
this is my old code in my component db site, linux permission is so high 
exeption work correctly.
   try
..........
   except
    Result := [lerr_LoginName, lerr_Password, lerr_ReadInfo, 
lerr_Expired, lerr_InActive];
   end;

this is new code, if application can't access or any connetion problem, 
error now popup to user
   try
...........
   except
    on E: Exception do begin
      Result := [lerr_LoginName, lerr_Password, lerr_ReadInfo, 
lerr_Expired, lerr_InActive];
       MessageDlg(PChar(Application.Title), E.Message, mtError, [mbOK], 0);
    end;
   end;


My mistake is: "if LoginResult = [lerr_LoginName]then"  this my old 
code. this is not correct, it has to be (lerr_LoginName in LoginResult)  
because more then one set items return and not aqual to one.

On my system (lazarus db etc.)has permission so no error, its work, but 
test system not setted correctly, I can't debug just add 
showmessage(''). No any error and no normal working and I been false 
alarm :)
Problem on me :( not enoughcalculate probability
