c++ visual studio form application serially reading data from arduino

Using Arduino Interfacing w/ Software on the Computer
1

hi!

iv made a c++ form application using visual studio. i want to read a string, serially printed/transmitted from my arduino mega and show the string on a text box in my form application. i have tried ReadLine() and a few other functions but I am unable to do so.

this is the arduino code:

String str;

void setup()
{
  Serial.begin(9600);
  
}

void loop()
{
  Serial.println("hello");
  delay(2000);
}

i have inserted a text box and a button on my form application. i want the hello to be saved in a string and want it to appear on the text box.
(or if therez a way to serially read characters, that can do my job too)

need help with the c++ code for the form application for this :confused: any kind of help will be appreciated!

I've not experimented with this class, but see if this might help:

But you have not shown any code for the PC side.

Frankly, C++ is a crappy way to build forms applications that deal with the serial port (or that don't, for that matter).

C# makes developing forms apps so much simpler, and reading and writing from the serial port is trivial. Check out the attached application, if you want to go the easy route.
