MessageBox function is not running on server (web mode)

[dynamo]

MessageBox function is running on localhost but not running on server.

 

or Can I use a useful function rather than MessageBox ,so it have to run without problem on DESKTOP and WEB.

 

procedure TuniForm4.UniBitBtn4Click(Sender: TObject);
begin
if MessageBox(0,'Are you delete this record...?','WARNING',MB_YESNO)=ID_NO then exit;

///------------

//-------------

end;

 

this code under WEB MODE

http://localhost:8077/ ---> is running

 

http://server:8077/ ---> is not running and gives the following error (attach file):

see demo sample Dialogs

MessageDlg is running on DESKTOP but is not running on WEB.You can test sample Dialogs:

 

uniButton5 ->Confirm:

 

 

procedure TMainForm.DCallBack2(Res: Integer);

begin

case Res of

mrYes : UniEdit1.Text:='YES';// UniMemo1.Lines.Add('YES');

mrNo : UniEdit1.Text:='NO';//UniMemo1.Lines.Add('NO');

end;

end;

 

procedure TMainForm.UniButton5Click(Sender: TObject);

begin

caption:=''; UniEdit1.Clear;

MessageDlg('Dialog2', mtConfirmation, mbYesNo, DCallBack2);

 

if UniEdit1.Text='YES' then begin

 

caption:='aaa';

end;

end;

For Delphi 2009+ you can use anonymous method (closure):

 

MessageDlg('Are you delete this record?', mtConfirmation, mbYesNo,
 procedure(AResult: Integer)
 begin
   case AResult of
     mrYes: UniEdit1.Text := 'YES'; // UniMemo1.Lines.Add('YES');
     mrNo : UniEdit1.Text := 'NO';  // UniMemo1.Lines.Add('NO');
   end;
 end);

thanks.Using MessageDlg ,UniEdit1.Text gets value of "YES" or "NO" but I have a problem this: (on WEB MODE)

 

Look at the following code:

 

procedure TMainForm.UniBitBtn1Click(Sender: TObject);
begin
 //--------is running-----------------------------
 MainForm.caption:='';   UniEdit1.Clear;

 MessageDlg('Are you delete this record?', mtConfirmation, mbYesNo,
 procedure(AResult: Integer)
 begin
   case AResult of
     mrYes: UniEdit1.Text := 'YES';
     mrNo : UniEdit1.Text := 'NO';
   end;
 end);
 //---------------------------------------------


 //--------------is not running------??????????????????????
 if UniEdit1.Text='YES' then   begin
     MainForm.caption:='aaa';
 end;
 //----------------------------------??????????????????????
end;

Hello,

 

In webmode there is no pause, the execution is already done/passed for the code you say '..is not running..'

 

Simply, may take required action in first dialogs callback procedure...

 

procedure TMainForm.UniBitBtn1Click(Sender: TObject);
begin
 //--------is running-----------------------------
 MainForm.caption:='';   UniEdit1.Clear;

 MessageDlg('Are you delete this record?', mtConfirmation, mbYesNo,
 procedure(AResult: Integer)
 begin
   case AResult of
     mrYes: DELETE...;
     mrNo : SKIP...;
   end;
 end);

 //--------------is not running------!!!   ALREADY PASSED
 if UniEdit1.Text='YES' then   begin
     MainForm.caption:='aaa';
 end;

end;
