how to use wait for event step

Hi,

I need to trigger wait for event step for my workflow but I am not able to trigger that .

Can anyany one of you tell me in detail what are the necessary config.and bindings i need to do for that .

Also i need to pass data from my report program(where i am triggering the event for the wait activity) to the workflow through event triggering for the wait step.

Please tell me how can I do that .

Thanks in advance.
