hello,
Please could you help me on this.
I have writen a small program in VC++ which only open a queue
and put message in the queue.
In my program i defined an ImqMessage variable which hold my message.
as i have a Dialog in my program my message text is stored in a CString variable.
when i put the message in the queue I do not have error. but I can not get this message from the queue.
the code I used to put the message in the is the following:
ImqMessage msg;
CString m_msg;
char buffer[ 256 ];
msg.useEmptyBuffer( buffer, sizeof( buffer ) );
msg.setFormat( MQFMT_STRING );
msg.setApplicationOriginData((ImqString) m_msg);
queue.setOpenOptions( MQOO_OUTPUT | MQOO_INPUT_SHARED | MQOO_INQUIRE);
queue.put(msg);
a)when using it like this is the size of my message text limited to 256?
b)how can i used an unlimited size?
c) when running this program from the server i can connect to the queue manager. but when i run this from the client i can not get the connection.
PS: amqsputc run fine on the client.
thanks for your help

Yes.

Use dynamic memory. Also, make sure your queue is configured to handle large messages. There is a max limit for the message on the queue, which is in GB.

You meed to link your program with "MQ Client" libraries so that i will work from remote machine.

Appendix A in Using C++ manual explains what libraries you should use to compile your program. For example, On Windows platform when compiling with Visual C++ you should link with imqb23vn.lib and imqc23vn.lib files. For server application you should link with imqb23vn.lib and imqs23vn.lib files.
