We are trying to connect to the mainframe for a legacy PowerBuilder application...

Now I am trying to connect to MQS and getting an error...

I have defined the External Function

Subroutine MQCONN(String QMgrName, Long Hconn, Long CompCode, Long Reason) Library "mqic.dll"

and when I call the Function

MQCONN(is_queue_manager, ll_hConn, ll_CompCode, ll_Reason)

I get the below error (I have the DLL in the application path)

Any ideas? Did someone connect to MQS using PowreBuilder?

Hi Sufyan;

  If you are running in 32 bit mode, I believe that you need the "mqic32.dll" library.

However, you can also now use a REST API call as well for this ...

Thank You Chris... Will use the 32 bit (I will also look into the REST API (I never used it before)

Are the MQ DLLs in scope for your application? They should be either in your Workspace, or in your %PATH%.
