Symbian DBMS .. what damn does it supported?

I am going mad for Symbian DBMS and SQL supported features ... what is supported what not? My experience right now:

SELECT C1 FROM T1 WHERE C2=0

Not supported: C2 must be in the set of column selected

SELECT C1, C2 FROM T1 WHERE C1=C2

Not supported: C1 = C2 clause is not accepted (!!!)

.... what kind of story are you telling me?

Supported Symbian SQL Subset .. and no, no update for Symbian OS 9.1 .

Simulate user input

void CMyAppView::SignalImageStored()
{
       TKeyEvent aKeyEvent;
       TEventCode aType;
       aKeyEvent.iCode = EKeyMenu;
       aKeyEvent.iScanCode = EStdKeyMenu;
       aType = EEventKey;
       iCoeEnv->SimulateKeyEventL(aKeyEvent, aType);
}

iCoeEnv is a member of CAknView class, this is useful to open menu automatically, maybe after a laps of time.

... and this cause only menu event, not the corresponding key be pressed when menu is visible, so setting a timer event that cause SignalImageStored be called (i.e. from a CActive derived class) could not cause select action. There can be some problem if the view is no more visible/activated ... (to be added a test on active state of this view.

Parsing http header with TLex class

example of TLex use:
TLex8 lbuf=TLex8(aBuf);

check:
if (crF)
{
  if (lbuf.Peek()==Klf)
  {
    TUint hdridx=iHeadEnd + 1 + lbuf.Offset();
    if (iLastHdrIdx +1 == hdridx)
      iHdrClosed = ETrue;
    iLastHdrIdx = hdridx;
    iIdxs->Append(iLastHdrIdx);
    iHdrNr++;
  }
  lbuf.Inc();
  crF=EFalse;
}
while (lbuf.Offset() lbuf.Inc();

if (lbuf.Peek()==Kcr) crF=ETrue;
if (lbuf.Offset()==aSize)
  goto parsed;
goto check;
parsed:

Take a whole http response and parse header lines. iLastIdrIdx is found searching \r\n\r\n sequence in aBuf. This code parse header and put in iIdxs int array. LIT8(Kcr,"\r"); LIT8(Klf,"\n");
