Visual Studio and Arduino serial port communication

Hi to all,

i cant send long numbers from Visual Studio to Arduino. i think its because of it can send just a byte from serial port. How can i send long numbers from Visual Studio to Arduino ?
Thanks

You can't sent ANYTHING from Visual Studio to the Arduino. Visual Studio does NOT have the capability to open the serial port.

You can write an application, in VB, C#, C++, Fortran, etc., using Visual Studio, and that application can use the serial port to communicate with the Arduino.

If you HAD done that, you would have posted the code.
