if understand question correctly, want know when checked state of 1 particular radio button (idc_radio1) changes.

then store state member variable in dialog class. int m_radio1checked; initialise in constructor 0 or 1 want, , use setcheckradiobutton() appropriately in oninitdialog().

then handle clicking of each radio button in message map:

on_bn_clicked(idc_radio1, &cmydlg::onradiobuttonclicked) on_bn_clicked(idc_radio2, &cmydlg::onradiobuttonclicked) on_bn_clicked(idc_radio3, &cmydlg::onradiobuttonclicked) on_bn_clicked(idc_radio4, &cmydlg::onradiobuttonclicked) on_bn_clicked(idc_radio5, &cmydlg::onradiobuttonclicked)

and in handler check change.

void cmydlg::onradiobuttonclicked() {   int oldstate = m_radio1checked;   int newstate = getdlgitem(idc_radio1)->getchecked();   m_radio1checked = newstate;   if (oldstate != newstate)     // ... }
