Message Interceptor Not Working RRS feed

  • Question

  • I'm working on an application which will send out a text message periodically and then listen for a reply. I'm using windows mobile 6 and .net3.5 with Message Interceptor to listen for the incoming messages.

    The code for the application is shown below. There is an infinite while loop which runs and is exited if a message is intercepted. I would prefer to use a timer but when the timer which is commented out in the below code is used instead of the while loop the application sends 1 text and then closes. With the current set up it runs correctly but does not intercept any messages.

    Originally this was a form application but now needs to run in the background and so I have moved it over to a console application. This caused many issues (switching form timer to threading timers etc.) 

    If anyone can see why this isn't working please help out this has been giving me hassle for about 3 days and I think i'm starting to go insane :(
