Introduction to MQe message filters
Filters allow MQe to perform powerful message searches. Most of the major queue manager operations support the use of filters. You can create filters using MQeFields.
MQeFields filter = new MQeFields(); filter.putArrayOfByte( MQe.Msg_MsgID, MQe.AsciiToByte( "1234" ) );
You can use this filter as an input parameter to various API calls, for example getMessage.
