Hi ,

I am trying to send sms to inbox on emulator.
sending works perfectly, but im unable to get any event notification .

here is my code

In fact you can observe the Inbox in the emulator too: if you "Send" an SMS (first time you should do that from the built-in Messages application, because you are going to be asked about the SMSC - specify any number you like), a file (messagex.sms or something) will appear in epoc32\winscw\c\smsout. Copy it to smsin, the file will suddenly disappear, and you will get an incoming SMS in the Inbox.

I just noticed that you apparently do not use "KObservedFolderId", so just try the above mentioned steps without modifying the code, and it may already work.

Hi wizard_hu_ ,

I got sms in inbox without doing anything.

But the problem is i didn't get any notification in my application.

i just called like this

TBuf<128> SMSText, PhoneNumber;
				SMSText.Copy(_L("Test Message"));
				PhoneNumber.Copy(_L("+911234567890"));// but ihave used this number...for my later use i have mentioned
				iSmsHandler->SendL(PhoneNumber, SMSText);

Hi.. everyone
i think i have the same problem too..
even if our code is slightly different

//from sms engine   
		 case EMsvEntriesCreated:
			 {
		            // Only look for changes in the Inbox KMsvGlobalInBoxIndexEntryId /draft KMsvDraftEntryId  
		            if (aArg2 &&  *(static_cast<TMsvId*>(aArg2)) == KMsvGlobalInBoxIndexEntryId)
		                {
		                CMsvEntrySelection* entries =  static_cast<CMsvEntrySelection*>(aArg1);
		                if( entries->Count() >= 1 )
		                    {
		                    iNewMessageId = entries->At(0);
		                    }
		                else
		                    {
					//Panic(ESmsEngineInternal);
		                    }
		                }
		            break;
			 } 
			 
		 case EMsvEntriesChanged: 
			 {
			// RDebug::Print(_L("DEBUG entries change +1"),__LINE__);
			 if (aArg2 &&  *(static_cast<TMsvId*>(aArg2)) == KMsvGlobalInBoxIndexEntryId )
				 {
					 CMsvEntrySelection* entries = static_cast<CMsvEntrySelection*>(aArg1);
					 if( entries->Count() < 1 )
					     { 
					       // RDebug::Print(_L("DEBUG ERROR!!! Panic(ESmsEngineInternal)"), __LINE__);
					     }
					 else if (iNewMessageId == entries->At(0))
					     {  
					    	RDebug::Print(_L("DEBUG entries KUidMsgTypeSMS %d"), KUidMsgTypeSMS);
						RDebug::Print(_L("DEBUG entries iSession->GetEntryL %d"), ( iSession->GetEntryL( iNewMessageId ) )->Entry().iMtm );
					   
						 if ( ( iSession->GetEntryL( iNewMessageId /*entries->At( 0 )*/ ) )
					    		 ->Entry().iMtm == KUidMsgTypeSMS )
					    	 {   
							 
						     //it doesnt go here			
					    	     iSelection->AppendL( iNewMessageId, 1 ); 
					    	     ReadNewEntry(iNewMessageId);
					    	 }
					     } 
				 }
		 		              
		 		  break; 
		    }

I tried what wizard suggested and i was able to make it work on symbian 3rd edition FP1.. the new entry was logged on text file
but when i switch it up to FP2.. the code doesnt work..
i tried to debug it per line and it turns out the new entry message type number is different with KUidMsgTypeSMS . . i dont know, maybe something wrong with this code

Please.. help us out masters
thanx

Hi.. everyone
i tried to debug it per line and it turns out the new entry message type number is different with KUidMsgTypeSMS . . i dont know, maybe something wrong with this code

Try to handle EMsvEntriesCreated case which will be triggered when there is a new entry in the messaging server. See this article where you would find SmsHander for S60 3rd.Zip and see the implementation of HandleSessionEventL. SMS Operations

[pemai23]

Correction..
i'm sorry that code works on FP2 too..
i reopened carbide and it works just fine..
thank you so much wizard_hu

[pemai23]

Hi.. again
sorry.. i got problem T_T
the HandleSessionEventL code works on the emulator
once i tried it on device..
the application will be terminated automatically when the incoming message's received..
Could you Give me some lights about the possible problem..

thanx

Enable the error messages as a first step: http://wiki.forum.nokia.com/index.ph...ded_panic_code - the last line of the section about S60 3rd edition contains a downloadable installer.

hi wizard..
thank u for reply..
here's what i got from Panic Observer


Panic details

error desc "This panic is raised by any operation which accesses an element of an array by explicit reference to an index number, for example, the Delete(), InsertL() and At() member functions or the operator Operator[].

here's the code..

could u tell me where it might be the error? because it works fine on the emulator..

Thanx

It is hard to guess, I think that "entries" always has an element; I usually do not even check. Consider making friends with On-Device Debugging. You can find various related resources in the Wiki, including screencasts for example.
