I have written a class in c# that uses the MSComm lib for serial communications to make calls to a remote device and retrieve data. The class has a method that when called, is writing the dial string to the port causing the modem to dial out and is then using the OnComm event to detect when the required data has come in and in case the data is correct it raises an event that also passes the data to the calling class which in turn calls another method of the comm class to terminate the call.

I would like to implement a calling class that loops through a number of such remote devices and for each one it performs the function described above. How can I implement this? It appears to me that in every iteration the loop has to wait for the event to be fired and if the data passed is correct it must terminate the call and move to the next iteration. How can I best implement such an operation?


Truly grateful for any help.

Besides how the specified functionality should be implemented, consider using asynchronous method calls if you want to be able to call a method and continue execution without waiting for it to return and be automatically notified when it does.

You can call every .NET method asynchronously by simply defining a delegate of the same signature as the method that is to be called asynchronously. After instantiating the delegate, you'll notice that for each method of your class, there's a pair of methods BeginXXX and EndXXX, where XXX is the name of the methods. These methods are used to asynchronously invoke and end the XXX method. When an asynchronous method call returns, you will be notified by means of a specified callback method.

Of course this is rather superficial discussion. I just wanted to point you to the right direction. Plz see the .NET documentation to learn how to implement this functionality.

I will try this and let you know,
