... or for a group of radio buttons you just create (the same way as above with 'AddVariable') an UINT member variable. You then can set this to be 0 for the first radio button, 1 for the second a.s.o. and call 'UpdateData(FALSE)' to set it - call 'UpdateData(TRUE)' later to recieve in that UINT variable which button was checked by the user.<br />
