Hello to you all ,

I Have a quesiton :

I have read the CCallHandler Example over the Internet and i wanted to know the following :
Is it possible to make in a single active object more than one asynch operation?
My intention is in the Code Snippet as comment :

void CCallHandler::RunL()
    {
    if( iStatus==KErrNone )
       {
        if( iLineStatus.iStatus == CTelephony::EStatusDialling )  
                  {
                          CTelephony::TRemotePartyInfoV1 RemInfoUse;
                           CTelephony::TCallInfoV1                   CallInfoUse;
                           CTelephony::TCallSelectionV1   CallSelectionUse;
                                               
                           CallSelectionUse.iLine = CTelephony::EVoiceLine;
                           CallSelectionUse.iSelect = CTelephony::EInProgressCall;
                                               
                           CTelephony::TRemotePartyInfoV1Pckg         RemParty(RemInfoUse);
                           CTelephony::TCallInfoV1Pckg                 CallInfo(CallInfoUse);
                           CTelephony::TCallSelectionV1Pckg         CallSelection(CallSelectionUse);
                                                               
                           iTelephony->GetCallInfo(CallSelection,CallInfo,RemParty);
                                    
                           if(iLineStatus.iStatus == CTelephony::EStatusRinging)
                            {                
                                     CallerNumber.Copy(RemInfoUse.iRemoteNumber.iTelNumber);
                            }
                           else if(iLineStatus.iStatus == CTelephony::EStatusDialling)
                            {                        
                                     CallerNumber.Copy(CallInfoUse.iDialledParty.iTelNumber);
                            }
                     }
           else if( iLineStatus.iStatus == CTelephony::EStatusIdle )
                                    {

                                             //Call a Certain Number                   
                         }
           else if( iLineStatus.iStatus == CTelephony::EStatusConnected )
                           {
                                                  //Send a DTMF String     
                           }
                     iNotifier->NotifyOutgoingCall(iLineStatus.iStatus, CallerNumber);
                    
                     /* Request the next notification */
                     iTelephony->NotifyChange( iStatus,CTelephony::EVoiceLineStatusChange,iLineStatusPckg );
                     SetActive();
               }
      }

Regards ,

So as long as your different requests are executed in queue, one after another, it's OK. But you have to wait the completion of the current request before launching a new one. If you want simultaneous requests, you need many active objects.

In Example : If i hangup already , i know i am in Idle State , so i DoCancel() on the last request and perform the next assignment?

In case you do have a request active, just call Cancel (which will call DoCancel where you do your canceling, depending on state).
