Hi,
I downloaded your code samples for Visual Basic and tried running them.
I have MQ Client installed on my machine and trying to access a remotr Queue.
I am getting error "File not found: MQM.dll".
I read some where that VB cannot make direct calls to MQM.dll and that we should use MQAXSTD.DLL instead.
If so, what does this dll come with?
If not how can I get it working.
I require it very urgently.
Thanks |

Hi,
The VB / MQ code that you download is the sample VB code that IBM ships with MQ (I current only have v5.1 & v5.2 posted).
Therefore, if your installed MQ Client is v5.3, you should be using the included VB samples (i.e. mq_install_dir\Tools\VB\samplVB6 ).
I have never heard of the MQAXSTD.DLL file.
I am not a VB expert but I believe you have 3 choices for coding VB apps: native MQ / VB MQI calls, COM and .NET.
For VB client code, you need to set 2 environment variables:
This variable tells MQ to use the client libraries (versus binding mode)
| Code: |
| GMQ_MQ_LIB=MQIC32.DLL |
This variable tells MQ where the queue manager is located:
| Code: |
| MQSERVER=CHANNEL1/TCP/server-address(port) |
where CHANNEL1 is the name of the SVRCONN channel
and server-address(port) is the IP/hostname and port # where your queue manager's listener is running.
Hope that helps.
Regards,

Make sure you dont use the ancient support pack ma04, and ensure you are picking up the correct cmq*.bas when the project is compiling. If you meant MQMSTD then thats definitely from the old support pack, I dont recognize the MQAXSTD (unless that is a similar wrapper to the mqax200 code from the old support pack?).
If you are using VB on a machine which has both client and server installed
You need to set MqType:
1. Select the menu option "Project - xx Properties" (where
xx is the name of the project).
2. On the tab labelled "Make", edit the field "Conditional
Compilation".
In the "Conditional Compiliation" field, enter (without the
quotes):
"MqType = 1" for the WebSphere MQ server
"MqType = 2" for the WebSphere MQ client
If you are using the activeX interface on a machine which has both client and server installed
The ActiveX class use a method known as 'late binding' when deciding which MQSeries API module (either MQM.dll or MQIC32.dll) to use. This mathod takes the approach that, if MQM.dll is present in the path, the application must be running as a server side application and as such uses MQM.dll otherwise it assumes that the application was meant to run as a client side application and uses MQIC32.dll. This can be overridden using the undocumented environment variable, GMQ_MQ_LIB which should be set to the full path of the dll to use (either MQIC32.dll or MQM.dll). |
