How does VC ++ enable the radio button and the checkbox is initially selected?

Checkdlgbutton (idc_check1, bst_unchecked); // 0 checkdlgbutton (idc_check2, bst_checked); // 1

(Cbutton *) getdlgitem (idc_radio_1)-> setcheck (1 );

You can also use Class Wizard to bind the variable to the control, set the initial value, and then call updatedata (false)

The setcheck () function is used. Table 1 is selected, and Table 0 is not selected.

All of the above are right. What I want to add is that if you are a radio button, you should combine it into a group, in this way, only a few radiobutton can be selected at the same time.

If the control you set is not in the control format, use the following statement getdlgitem (idc_button_radio1)-> setcheck (true );

Checkradiobutton (id_1, id_10, id_3); indicates that id_1 to id_10 is a group of radio, and id_3 is selected for single choice. However, id_1 to id_10 must be continuous.
