Hello
We are working on WebSphere MQ application using C++. We need to connect to a local directory, take a copy of the files(hundreds), edit each file one after one and send to the queue. I'm able to put a file on the queue, but how do I poll the file directory for any new files and pick them like FIFO.
Env : MB 7, MQ 7.1, Windows

Same way you normally do with a file reading C++ application.
Unless you're using one of the WMQ File->queue components and you've not mentioned it. Base WMQ has nothing to do with files.

| We are not using any WMQ File queue components. Have to do this if its possible with WMQ application in C++ or a simple plain C++ program. |

Do a quick google search for 'how to read a directory in c++'.

And remember the Halting Problem.
If all you have is the name of a directory, you don't know if any of the files in it are "ready" to be processed, because you don't know if any of the programs writing those files have halted. |
