You can mimic this quite easily yourself by making a custom radiobutton, or just implement it for that single form you' re using this functionality like the code below.
Define some variable in your form and give it a default value on load.
__int64 radioClickTime = (__int64)GetTickCount();
void CdemoDlg::OnClickedRadio2()
{
__int64 tempRadioClickTime = (__int64)GetTickCount();
if((tempRadioClickTime - radioClickTime) < 300)
{
}
radioClickTime = tempRadioClickTime
}
Good luck!
