I don't know enough to answer your question, but if you are using WMQ V7.0 and an unmanaged client don't do this:
| Code: |
Hashtable props = new Hashtable();
props.Add(MQC.HOST_NAME_PROPERTY, "U4VMMQNP109(1414)");
props.Add(MQC.CHANNEL_PROPERTY, "CSM.SVRCONN.01"); |
Use the mqclient.ini file in conjunction with a CCDT, or at least externalise the details into an editable file, even for a test application because then it's transportable.

same for any MQ object name such as queue name, put in somewhere external to the code.
Setting format before a get does nothing. The format is in the message MQMD.
You shoud use MQGMO_CONVERT on all string messages.
Don't open the queue for each GET (put the open before the GET loop).
Close the queue after you have finished doing the GET loop.
Disconnect from the queue manager after the close.
Check the buffer size you provide for the get. It's likely that you have only part of the message if it's too small.
Try not using SYNCPOINT to see if that fixes it - if it does your commit logic is wrong.
Lots of things to fix before trying again. MQ does not get two messages for one get - you can be sure of that. |

Otherwise if you see different behavior on one machine than on another for "the same" code, then either it's not the "same" code somehow, or there's something wrong with one of the machines.
Are you using a full MQ Client install in each case, or are you copying DLLs?
Are you rebuilding your app for 64bit ?
Do you see the same behavior with the nmqsget sample? |

Are you using the latest version (V7.0.1.4)?

The errors I have pointed out need fixing. Whether or not it appears to work there are some very bad coding practices in your code. Not to correct these would be unwise. |

Then you have a problem with your buffer and a problem with your error handling.
The other problem is that you've edited your first post to remove all the details so newcomers like me are just guessing what you're saying.
