tim cummings via .NET 247

I am writing a program that interfaces with a cars pcm via theserial port and recieves data (such as rpm) at an interval, oflets say 1 second, and then formats it. The problem is, I wouldlike to display the data that is coming in over the port andhave it continously displayed until the user decides they wantthe data to stop.

Currently the only way I have found to show the data in a"streaming" fashion is to loop the request, but once I do that Icannot break out of the loop (PDA wont let me click on any otheritem on form while loop running).

Any suggestions, or other Ideas on how to start and stop the dataupon user request

thanks,
tim

Do the work in a different thread, and use Control.Invoke to update the
UI on the UI thread.

See
http://www.pobox.com/~skeet/csharp/multithreading.html#windows.forms
for more details. Note that on the Compact Framework, there are
limitations about which delegates you can call Control.Invoke with - I
believe you can only use EventHandler delegates, basically.
