MQSeries.net :: View topic - Connecting Remote Queue using C langage- Error MQCONNX 2058

Hello all,

I have problem connecting a remote queue using the C langage.

Using the Java langage, i don't get any problem to connect this remote queue but using C, i get
always the same error with MQCONNX : the 2058 error which means that the queue does not exists.

When i want to connect to the local queue installed on my computer using my C code,
i don't get any problem, my code works well.

Maybe i forgot something in my code to connect a remote queue.
Maybe i need to specify the hostname and the port of the server on which
is my remote queue ?

Here are all the defintion of the queue manager i want to connect on :
Manager Name:QMIDTCC
Channel : Channel.TEST
hostname: mqm_test.emea.cib
port : 1948

I can ping the server. No problem of firewall.It works in java ....

I m using windows.

Please give me some help because i absolutely don't know why i can't connect htis remote queue .

Thanks a lot
Eric

PS:Here is the C code i m using to connect the queue :
