Recieve Data From Serial Com Port C# In One Line And Convert To integer

ahmedsa

Hi guys I have problem. I have code that takes data from serial com port for weighing machine, it's working okay, but receives data in more lines. I'm trying to make it receive data in one line.

In the code below I need to take weight from weigh bridge machine automatically by timer using Visual Studio 2005. It works, but I receive weight values in more lines. I need to receive weight in one line and automatically update and convert it to an integer.
