Hola Happy New Year !! ~ im doing this project on C# programming and im stucked on it for many days.
What i need to do is to read either '0' or '1' from a circuit ( external circuit board is connected to my laptop via serial port ), and based on either '0' or '1'received, different videos ( video 1 or video 2) will be played.
The following is my source code by far, and there're 6 errors which popped out and i have no idea how to fix it.
using System;
using System.Collections.Generic;
using System.Text;
using System.IO.Ports;
namespace cs_open_videos
{
class Program
{
static void Main(string[] args)
{
OpenSerialPort();
//String fileToOpen = "C:/myog.avi"; System.Diagnostics.ProcessStartInfo ps = new System.Diagnostics.ProcessStartInfo("C:/Program Files/Windows Media Player/wmplayer.exe/play/fullscreen", fileToOpen); System.Diagnostics.Process.Start(ps);
}
SerialPort com=new SerialPort();
private void OpenSerialPort()
{
SerialPort com=new SerialPort();
com.BaudRate=38400;
com.Open();
com.DataReceived = OnRecieved;
}
private void OnRecieved(object sender, SerialDataReceivedEventArgs c)
{
char c = com.ReadChar();
switch ©
{
case "0":
String fileToOpen = "C:/video1.avi"; System.Diagnostics.ProcessStartInfo
ps = new
System.Diagnostics.ProcessStartInfo("C:/Program Files/Windows Media Player/wmplayer.exe/play/fullscreen", fileToOpen); System.Diagnostics.Process.Start(ps);
case "1" :
String fileToOpen = "C:/video2.avi"; System.Diagnostics.ProcessStartInfo ps = new
System.Diagnostics.ProcessStartInfo("C:/Program Files/Windows Media Player/wmplayer.exe/play/fullscreen", fileToOpen); System.Diagnostics.Process.Start(ps);
play();
}
}
}
}
8 errors occured in my coding, and are shown in the following:
Error 1
An object reference is required for the nonstatic field,
method, or property 'cs_open_videos.Program.OpenSerialPort()'
Error 2
The event 'System.IO.Ports.SerialPort.DataReceived' can only appear on the left hand side of += or -=
Error 3
A local variable named 'c' cannot be declared in this scope because it would give a different meaning to 'c', which is already used in a 'parent or current' scope to denote something els
Error 4
Cannot implicitly convert type 'int' to 'System.IO.Ports.SerialDataReceivedEventArgs'
Error 5
A value of an integral type expected
Error 6
A local variable named 'fileToOpen' is already defined in this scope
Error 7
A local variable named 'ps' is already defined in this scope
Error 8
The name 'play' does not exist in the current context
Can anybody pls help me fix this? Thank you in advance
