I have a program to trigger the OnComm event in the View class to read data from the serial port. Then I inserted an MSChart control to draw a real-time data curve. But I don't want to draw in the View class, I want to draw in a popup dialog. What bothers me now is: How to get real-time data from OnComm in the dialog class? ?
I asked an expert, and he gave me a sentence: add a message, send a message after receiving a data in OnComm. . . Then he left. . .
I don't quite understand (because of qualifications), ask you masters, what should I do? Please tell me please

Yeah, I put it on the dialog. The problem is: each time you read a data from the serial port, trigger an OnComm event (in the View class), accept it, I want to pass it to the dialog class for drawing, and the dialog box may not be created when the data is received The problem is that I don't know how to pass the data. How to use message?

If a dialog class object is created in the View class, and a suitable Arrange for storing data is created in the dialog class, the data read by the serial port is stored in the Arrange of the dialog class in the OnComm event of the View class. Are the data sources and tools for drawing in the dialog class? It should be easy to operate!
personal opinion for reference only:)

Isn't this similar to implementing a progress bar in another dialog?
It should be able to handle it similarly, delivering messages in real time.
