I am using support pak MA0H, a great little utility that lets you watch the depths of your queues in real time (no hitting refresh constantly).
I run it by configuring a bat file to hold the MQSERVER variable for the particular Queue Manager I want to connect to, as well as the queues I want to watch. I would like to give this app to one of my in house clients so they can monitor their development queues without constantly calling me up.
Problem is, watch q is pretty powerful. You can connect to any QM in our system, and then clear queues or put messages. So if I give them the app with the associated bat file configured just to run against their stuff, I dont want them to have the ability to start copying and editing that bat file.
Any ideas on how to create an unreadable/uneditable bat file that can still be executed and copied?

If this is to run on windows, you could easily write a C program that calls the
"system()" system call which takes as a parameter the name and paramters of the program to run and starts it. I think if you use the "putenv()" system call, you could set the environment variable before calling system ...
something like:
| Code: |
main(int argc, char argv[])
{
putenv("MQSERVER=xyz");
system("myprog -parm myparms");
}

 Don't know C. (Mainframe guy here)
I found an app on the web (http://download.com.com/3000-2229-9038029.html) that takes a bat file and compiles it into an .exe file, but it isn't supported on NT/2000. I'm gonna take my bat file home to my 98 pc, run the app there, and bring back the exe to see if it runs at work on the NT pc.

Hi guys,
when I tried to do something like that in the days of NetBIOS MQClients, which needed the MQNAME (I think) variable to set the NetBIOS name for the client application, I ran into the problem that environment variables are picked up by the C runtime during program start. A putenv() call within the program was not honored by an application that was invoked from within the same program using the system() call.
So, if you are getting a 2059 on your compiled BAT file, this would be the first thing to think of as the possible cause.
I tried a lot of adventurous stuff at that time to get it to work; without success.
But you can probably workaround it by using a channel table file that you distribute with your compiled EXE. However, if the MQSERVER variable takes precedence of the MQCHLLIB/MQCHLTAB setting (which I don't know from the top of my head), an MQ aware user might always find a way around it.
Hope that helps,
Stefan |

| Couldn't you also use the MQCONNX to set your client connection? I thought that the MQCNO structure was created so that you could pass in a pointer to a MQCD which could contain the information that you would have passed in via the MQServer environment variable. |

There use to be a batch file compiler that would compile a batch file to an executable. I dont know where to find it, but I will ask one of our NT admins if
he knows where to get it.
