[VCL and UniGui Communication]

Hi,

 

I would like to ask how would a commonication look like between VCL and UniGui applications. Unigui would handle clients and send workloads to VCL, VCL would do some engine work proccessing, database R/W and returning respondes to UniGui.

 

What would be the bast way to implement such solution.

 

Tnx^

[Memory release after session has been terminated]

Ok I forgot about built in server monitor. So... internal memory seems to be ok. when session is created and older terminated it raises and drops (to same value as before). But process memory does not drop. Why would that be? Also, why is Memory(Process) in server monitor and memory consuption in task maneger not equal?

[Memory release after session has been terminated]

When I open new session application consume some of RAM, but when I terminate session, application doesn't release as much RAM as it took it for the session.

[DBGrid with big DataSet]

If I would then fetch 100 - 1000 records, then I should I implement logics for next page and last page. But how would I then filter and sort records. Now I use FDQuery.Filter and FDQuery.Indexes for sort.

[DBGridGetCellValue]

If cell hold some default value, I would like to remove it in time of editing (so that user don't need to delete this default value, but it would be blank for editing). If user doesn't enter enything I would than set back the default value (which I can do in OnSetCellValue).

[DBGridGetCellValue]

I know there is event on DBGrid -> OnSetCellValue. It is fired when you leave cell's editing. Is there a event alike when I enter the cell. I suppose it would be something like OnGetCellValue, but it does not exist. Where can I retrive call value when I enter cell's editor?

 

Thanks in advance.

[UniMemo AutoSize]

Hi,

 

how can i make memo with autosize when text wrap. I would like memo with 1 line and than when wordwrap happens i would like to increase memo height for 1 line. I've tried code from another post seen below, but doesn't seems to be accurate:

function TPaginaPrincipal.TextWidth(s: TUniLabel): Integer;
var
  c: TBitmap;
  f: TFont;
begin
{ uma forma de calcular o tamanho de um texto na janela se o canvas não atualiza via ajax }
  c := TBitmap.Create;
  f := TFont.Create;
  Result := 8 * Length(s.Caption);
  f.Height := s.Font.Height;
  f.Size := s.Font.Size;
  f.Name := s.Font.Name;
  f.Style := s.Font.Style;
  try
    c.Canvas.Font.Assign(f);
    Result := c.Canvas.TextWidth(s.Caption);
  finally
    c.Free;
  end;
end;

How can I accomplish this?

[Accessing UniMainForm]

Hi,

 

I'm having a problem accessing UniMainForm from my application. I have 1 Main(MainForm)  which is having 1 (Application) datamodule and that module is having another 1 (Application) datamodule.

 

Form

 |_ DataModule 1

       |_DataModule 2

 

If I understand UniMainForm correctly it is created  for each session and its basicly datamodule(Shared unit) for whole application.

 

Now... I'm creating threads in datamodule 2 and trying to write data to UniMainForm, but what I get is

 

UniMainModule.CreatedTaskIns:= ATaskIns.Key;

 

I Get access violation 0000064. I tried to read that variable from Datamodule1 and works good. It seems like i cant retrive current session from thread.
