Hi alt.
There are several exceptions in my log files after 24 hours of working smpp client.
1.
IsConnected error
Exception:Thread was being aborted.
TargetSite:Int32 select(Int32, IntPtr[], IntPtr[], IntPtr[], System.Net.Sockets.TimeValue ByRef)
StackTrace: at System.Net.UnsafeNclNativeMethods.OSSOCK.select(Int32 ignoredParameter, IntPtr[] readfds, IntPtr[] writefds, IntPtr[] exceptfds, TimeValue& timeout)
at System.Net.Sockets.Socket.Poll(Int32 microSeconds, SelectMode mode)
at ALT.SMS.SmppClient.get_IsConnected()
Data:System.Collections.ListDictionaryInternal

2.
Receive fail
Exception:An existing connection was forcibly closed by the remote host
TargetSite:Int32 EndReceive(System.IAsyncResult)
StackTrace: at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult)
at ALT.SMS.SmppClient.eMfdLFjKR(IAsyncResult )
Data:System.Collections.ListDictionaryInternal

After this one i get the "ESME_RBINDFAIL" status for a long time and then the following exception:

IsConnected error
Exception:Object reference not set to an instance of an object.
TargetSite:Boolean get_IsConnected()
StackTrace: at ALT.SMS.SmppClient.get_IsConnected()
Data:System.Collections.ListDictionaryInternal

Please could you try last version 2.8.1.

ESME_RBINDFAIL error occurs when an access has a limit of concurrent connections. Because of network problems SMPP server still think that client is connected and does not allow to bind with second connection.

Hi alt.
I have donload the 2.8.1 version. It is working for 4 days without any errors, thanx. But i have one more question:
Sometimes i can't get the delivery report in evDeliverSmComplete event.
SmppClient.GetMessageText(data.UserDataPdu.ShortMessage, data.DataCoding); return the empty string because some of the messageID in delivery reports has a different size. SMSC administrator said that the messageID may contains up to 64 bytes. Could you please tell me how can i convert data.UserDataPdu.ShortMessage data to ascii string?
System.Text.Encoding.ASCII.GetString have no result...
Thank you.

fixed in version 2.8.2

Note that you can also get message Id using code

Code: Select all

TLV receiptedMessageId = data.Optional[OptionalTags.ReceiptedMessageId];
if (receiptedMessageId != null)
{
      string messageId = SmppClient.GetMessageText(receiptedMessageId.Value, DataCodings.ASCII);
}
