SERIAL PORT DATARECEIVED EVENT NOT FIRING SERIAL

SMSR.GetData () // kicks of the serial port to get data. Net5 console app, even though SerialPort.ReadExisting() shows there is data. When the SP.DataReceived event fires, SPDataReceived does sBuffer + SP.ReadExisting () to get the data from the port. SerialPort.DataReceived() event not firing in.

If a method is simply hidden, the implementation to call is based on the compile-time type of the argument this. SMSR.GetData () then starts a timer to be sure not to wait forever for the SPDataReceived event.

If a method is overridden, the implementation to call is based on the run-time type of the argument this.

Register to the DataReceived event of the SerialPort as so: serialPort1. The practical difference between overriding and hiding is as follows: Since you are sending from the Arduino the received serial data back to the C application ( Serial.print (message) ), I would advise to check what you receive on the C side. Hiding is the definition of a method in a derived type with a signature identical to that in one of its base types without overriding. Overriding is the definition of multiple possible implementations of the same method signature, such that the implementation is determined by the runtime type of the zeroth argument (generally identified by the name this in C#). Everything is fine first time around, but if I quit my application and restart a few times, pretty soon (usuaully the second or third restart) the DataReceived event stops firing on the SerialPort object.

SERIAL PORT DATARECEIVED EVENT NOT FIRING CODE

For this I have written the code but the serialPortDataReceived() event never fire in my application. I want to read same 'hi' message from COM1. Now this same application will try to read data from same COM1 i.e. This is often used to group conceptually similar operations, such as overloading + to work with BigInteger and with String: both operations seem sensible to use + for (unless you think that all overloads of + should define Abelian groups - the String overload doesn't). Bluetooth GPS reciever that is paired to a serial port but Im experiencing odd behaviour from the CF 2.0 SerialPort class. I am trying to create an application which will send a mock data on Serial Port COM1 for example a string 'Hi'.

Each signature takes different arguments, and is essentially a distinct function, no different than if the multiple functions had different names.

Overloading is the definition of multiple possible "signatures" of a single method or operator.
