I get this error MQRC_UNEXPECTED_ERROR when I call the ReadUTF() method. I am using MQ V5.3. A friend of my is using the same routine and no error. We both using the same .NET assembly version and his product version is 6.0.2.0.
| Code: |
private void ReceiveMQ_Click(object sender, System.EventArgs e)
{
try
{
MQEnvironment.Hostname = "101.222.212.XXX";
MQEnvironment.Channel = "SYSTEM.DEF.SVRCONN";
MQEnvironment.Port = 1545;
MQQueueManager qMgr = new MQQueueManager("TA1.QA.QM");
String qName = "QAL.SQ.QA.01";
int OpenOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT;
MQQueue system_default_local_queue =
qMgr.AccessQueue(qName, OpenOptions);
MQMessage retrievedMessage = new MQMessage();
MQGetMessageOptions gmo = new MQGetMessageOptions();
system_default_local_queue.Get(retrievedMessage, gmo);
String msgText = retrievedMessage.ReadUTF();
MessageBox.Show("The message is: " + msgText);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

The same routine but if I change the readingUTF() method to to ReadString() then I don't get any problems but I can not able to read the text. Do you have any ideas? |

Is the data you are reading in the correct format for readUTF():
| Quote: |
The string in the message consists of a 2-byte length followed by the character data.

Cheers.

| The pepole who put the messages on the queue confirm that they used UTF-8 format. My friend can read it. |

UTF-8 is NOT the same as the results of a writeUTF call.

You need to use writeUTF and readUTF as a pair, on both ends. Otherwise just use the standard text API...
