Hi
I installed MQClient on my NT PC and I connect to Queue on a remote machine to get messages (MQGETX). After getting a message I want to close queue (MQCLOSE) and disconnect from Qmanager (MQDISC). But as soon as MQDISC is called, my application crushes.
Can someone please help. |

Do you know if the crash is happening inside the MQDISC call or after the MQDISC call returns?

| Does your crash generate an *.FDC file in the errors subdirectory? What version of WMQ are you using? |

Hi
It crashes on MQDISC not after it.
My version is 5.3
It does not generate any fdc file.
All I get is Application error:The memory could not be written. |

| You are wrong. If it crashed inside MQDISC you would get an FDC. The app is crashing in your own code. |

Hi Brandon
This piece of code works:
MQCLOSE gHcon, gHobj, C_options, CompCode, Reason
what is wrong with this piece of code?
If gHcon Then
MQDISC gHcon, CompCode, Reason
End If
as soon as execution gets to: MQDISC gHcon, CompCode, Reason
my application crashes.
How can it be my code that is causing the problem? |

Please bear in mind that the queue manager is on a remote machine and not local machine.
The MQDISC works fine if my application is running on PC on which MQ Server is installed and the queue is local. as soon as it runs on PC on which MQ Client is installed and the queue is on a remote machine, then there is a problem. |

Hi
I suspect gHcon can't be written to. It is input to the MQCLOSE call but input/output to MQDISC
Cheers
