| I'm passing an XML message from a CICS/IMS/COBOL II program on an OS/390 to a VB app running on NT 4.0. The max message size on the Q is set to 4mb, but the string buffer in the VB app has a limit of 64k. The data from the legacy system is such that the message length could exceed 64k. Any ideas on how to get a larger message into VB? Do I have to use segmented messages? |

Yes, there is a fairly easy solution to this, assuming you are calling the MQI MQGET from VB directly. Declare a variable length string, and then use the Space() function to create a string of spaces using some large number. Then pass this string and its size into the MQGET call.
It will look something like this:
Dim buf as String
Dim msglen as Long
msglen=100000
buf=Space(msglen)
MQGET Hconn, hQueue, md, gmo, msglen, buf, DataLength, CompCode, Reason
Hope this works for you. |

| Version of MQ used is 5.2. I am running the MQSeries Server on Windows NT and the MQSeries Client is on Windows 2000 Professional. The Client and the Server is on a different Machine. I am using MQSeries Automation Classes for ActiveX reference. I wrote a program in Visual Basic 6.0 which is putting a message on a request queue and I am getting back a message from the reply queue. The message which i am getting back from the reply queue is getting truncated. How can get back a message without being truncated. Is there any parameter that i should set. Thanks |
