CFRunLoopRun() problem
<p>i had  a problem  on CFRunLoopRun()</p>

<p>and here is the code 
after clicking the button , it Stops in CFRunLoopRun() method for some time ,
can any one help me wat to do next...........</p>

<p>AND my MAIN Problem IS i Have to Connect With BOCA printer USing IP Address and Port Number , and  I had Done Up to Sending Messages to The BOCA, but My problem how can i get return response , or how can i Know that i was connected to Printer , And the printing message should be send when my system and BOCA printer Should connect one NETWork Connection ........  </p>
