C# for smartphone

sb bk

Hello;

I have an application which was written in C# for a smart phone (HTC) with windows mobile.

The goal of this app is to communicate with an device through a bluetooth with COM port. This works fine,

If I made changes to this application to work simultaneously with two devices with two COM ports; although there is no error in the code, by running the app on the smart phone, it crashed. The error is for Serialport. I couldn't figure out the problem.

If anybody can help me please let me know to send you whole project (it may better to send it to your email, if possible).

Cheers

My advice is the same as any other time that someone asks for help based on a problem description such as "doesn't work" or "crashed"; be specific. It is rare for problems to be solved based on problem descriptions such as that. A crash is usually the result of another error that is ignored by the program. Ensure that your program uses try/catch blocks to catch errors and that it catches errors that must be determined in other ways. Learn how to put error reports in your program that helps you be specific about where the error occurs.

I am sure that my smartphone supports two ports. If I run the application which works for one port two times, and assign different port number, it works fine. The problem is when I merge this two application into one application.

Thanks

What kind of name is "sb bk" :)
I am not an expert on smart devices but It looks like your phone does not support the port or did not like the call.
