单选按钮和复选框都是一种特殊的按钮，窗口类名称都是button，只不过增加了一些特殊的窗口样式罢了。单选按钮的样式为BS_AUTORADIOBUTTON，复选框的样式为BS_AUTOCHECKBOX。要想为单选按钮分组，可以增加WS_GROUP样式。设置了 WS_GROUP 样式的单选框为一组中的首元素，随后的所有单选按钮都和它在同一组，直到下一个设置了 WS_GROUP 样式的单选按钮。

下面的代码，将实现上图中所示的单选按钮和复选框：

//窗口过程
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam){
    PAINTSTRUCT ps;
    HDC hdc;
    static HFONT hFont;  //逻辑字体
    //一组单选按钮
    static HWND labSex;  //静态文本框--性别
    static HWND radioMale;  //单选按钮--男
    static HWND radioFemale;  //单选按钮--女
    //一组单选按钮
    static HWND labMarriage;  //静态文本框--婚姻状况
    static HWND radioMarried;  //单选按钮--已婚
    static HWND radioSingle;  //单选按钮--未婚
    static HWND radioSecrecy;  //单选按钮--保密
    //一组复选框
    static HWND labPet;  //静态文本框--你的宠物
    static HWND checkboxDog;  //复选框--狗
    static HWND checkboxCat;  //复选框--猫
    static HWND checkboxFish;  //复选框--鱼
    static HWND checkboxOther;  //复选框--其他
