Problem getting Modal Result

General Help
1

Hi all,
I’m trying to create a password dialog box but it doesn’t seem to be returning the modal result correctly

On return Im testing for mrOK but I never seem to get mrOK returned

Can some one guide me on this

So the form is created such at runtime

procedure TConfig_Form.Test_Connect_BtnClick(Sender: TObject);
Var
  The_Form: TPasswordDlg;
begin
  try
    The_Form := TPasswordDlg.Create(Self);
    The_Form.Test := '12345';
    The_Form.ShowModal;
    if The_Form.ModalResult = mrOk then
      Test_Connect_Btn.Caption := 'yes'
    else
      Test_Connect_Btn.Caption := 'no';    *<<<<<<< but I only ever seem to get this
  finally
    if Assigned(The_Form) then
      FreeandNil(The_Form);
  end;
end;

and in the password dialog box I have

procedure TPasswordDlg.OKBtnClick(Sender: TObject);
begin
  if PASSWORD.Text = Test then
    ModalResult := mrOk
  else
    ModalResult := mrNo;
  Close;
end;

Thanks in advance
Grant

I assume you have checked and made sure that the OKBtn has its ModalResult property set to mrNone?

You can also use this code:

if The_Form.ShowModal = mrOK then

unrelated to the question, I fixed your code formatting.

FYI, to have the forum syntax highlight code

````delphi
code goes here
````

If you edit your post you will see how it works.

From memory you don’t need to call close after you set the modal result of the form. Does it make a difference if you don’t call close?

It might make more sense or make for cleaner code to use the form’s OnCloseQuery method and just leave the button’s ModalResult as mrOk

Seems to me a strange way of checking for modalresult. Why not just
“if The_Form.ShowModal = mrOK then”?

If you might have more than one important return type from the modal form …
