Thank you in advance. ^___^

-. My work environment
Windows 10, Visual Studio 2017 (v141)

-. about "HexCtrl - DATA_MSG, DATA_VIRTUAL"
Can you give me some examples of usage in simple code?
I tried to do it based on your explanation, I am often not successful.

You have to be more specific. What exactly do you have issues with?

You can take a look at the Pepper app, it features exactly DATA_MSG approach.
The message handling code can be found here

-. function
if i click HexCtrl,
1) editbox1 = Caret . it will be clear using "m_myHex->GetCaretPos()" + HEXCTRL_MSG_SETSELECTION.
2) editbox2 = Data. what can i do for this function? DATA_VIRTUAL? + HEXCTRL_MSG_SETSELECTION.
I read about Virtual Handler, but I don't know how to use it.

You want to get a data (byte) from a given offset, am i right?
If so, well, data is always external to HexCtrl, you set it in SetData method.
So, you already have your data pointer somewhere, just use ptrYourData + m_myHex->GetCaretPos();

Alternatively you can use m_myHex->GetData( { m_myhex->GetCaretPos(), 1 } ); interface method.
