VC + + dynamic generation of Group RadioButton button Group

Let's talk about statically created methods:

Radio buttons are also part of the CButton class, but because radio buttons are always used in groups, it differs from normal buttons in production and use.
Suppose you have three radio buttons that make up a group, and initially, the first radio button is selected.
Let's take a look at the static authoring method: Place three radio buttons in the dialog box and set the properties as follows:
Radio1 properties: Visible, Group, Tab stop, Auto
Radio2 properties: Visible, Tab stop, Auto
Radio3 properties: Visible, Tab stop, Auto
Such a property setting divides the three radio buttons into a group, they can only have one selected at a time, and if there are other groups of radio buttons in the dialog box, they will not interfere with each other. However, the first button is not selected at this time. Then use ClassWizard to add variables to this set of radio buttons, where you simply add a variable for the first radio button. Set variable named M_radio, type int. In the constructor ClassWizard set the value of M_radio to-1, we change it to 0 so that when you run the program you can see that the first radio button is selected. After that, you should also add a click response function with ClassWizard for three radio buttons, and modify the value of M_radio to correspond to three radio buttons.

At this static creation, the group property is manually specified. So how do you specify this property when you create it dynamically? I found a circle in all the methods, and I didn't find it.

That's where it's going to be set up, there's gotta be a way! That is the only way to save, is the ModifyStyle method, see if there is a corresponding style in this method!

I checked the style of the button first.

Find all the styles, there is no corresponding settings in the GROUP, and only a bs_groupbox, I tried, this style means that the button is transformed into a GROUPBOX, not the designated GROUP. No. In addition, you can only find a layer of style is the style of CWnd.

There really is a ws_group, this is what I want, so

Here's how to create a button group dynamically!
