接下：VC++简单绘图 MFC消息映射机制 MessageBox函数
You construct a CButton object in two steps. First, call the constructor and then call Create, which creates the Windows button control and attaches it to the CButton object.
If the WS_VISIBLE style is given, Windows sends the button control all the messages required to activate and show the button.
Apply the following window styles to a button control:
用两个步骤构造一个CButton对象。首先，调用构造函数，然后调用Create（创建Windows按钮控件并将其附加到CButton对象）。
如果给出了WS_VISIBLE样式，Windows将向按钮控件发送激活和显示按钮所需的所有消息。
在按钮控件上应用以下窗口样式:
WS_CHILD Always
WS_VISIBLE Usually
WS_DISABLED Rarely
WS_GROUP To group controls
WS_TABSTOP To include the button in the tabbing order
Button Styles：
| Type | Description |
|---|---|
| BS_3STATE | Creates a check box button with three states: BST_CHECKED, BST_INDETERMINATE, and BST_UNCHECKED. Clicking on the button sends a BN_CLICKED notification to the owner window but does not change the state of the button. By default, associated text is displayed to the right of the check box. To display text to the left of the check box, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_AUTO3STATE | Creates a check box button with three states: BST_CHECKED, BST_INDETERMINATE, and BST_UNCHECKED. Clicking on the button sends a BN_CLICKED notification to the owner window and changes the state of the button. The button states cycle in the order of BST_CHECKED, BST_INDETERMINATE, and BST_UNCHECKED. By default, associated text is displayed to the right of the check box. To display text to the left of the check box, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_AUTOCHECKBOX | Creates a check box button with two states: BST_CHECKED and BST_UNCHECKED. Clicking on the button sends a BN_CLICKED notification to the owner window and changes the state of the button. By default, associated text is displayed to the right of the check box. To display text to the left of the check box, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_AUTORADIOBUTTON | Creates a radio button with two states: BST_CHECKED and BST_UNCHECKED. Radio buttons are usually used in groups, with each group having a maximum of one checked option at a time. Clicking on the button sends a BN_CLICKED notification to the owner window, sets the state of the clicked radio button to BST_CHECKED, and sets the states of all other radio buttons in the button group to BST_UNCHECKED. By default, associated text is displayed to the right of the radio button. To display text to the left of the radio button, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_CHECKBOX | Creates a check box button with two states: BST_CHECKED and BST_UNCHECKED. Clicking on the button sends a BN_CLICKED notification to the owner window but does not change the state of the button. By default, associated text is displayed to the right of the check box. To display text to the left of the check box, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_COMMANDLINK | Creates a command link button. A command link button is a command button specific to Windows Vista that displays a green arrow to the left of the main text and a note below the main text. You can set the note text using CButton::SetNote. |
| BS_DEFCOMMANDLINK | Creates a command link button. A command link button is a command button specific to Windows Vista that displays a green arrow to the left of the main text and a note below the main text. You can set the note text using CButton::SetNote. If the button is in a dialog box, pressing the ENTER key sends a BN_CLICKED notification to the dialog box even when the button does not have the input focus. |
| BS_DEFPUSHBUTTON | Creates a command button that has a heavy black border. If the button is in a dialog box, pressing the ENTER key sends a BN_CLICKED notification to the dialog box even when the button does not have the input focus. |
| BS_DEFSPLITBUTTON | Creates a split button. A split button is a command button specific to Windows Vista that contains a button adjacent to a drop-down arrow. When you click the button, the default command is executed. When you click the drop-down arrow, a menu of additional commands appears. If the split button is in a dialog box, pressing the ENTER key sends a BN_CLICKED notification to the dialog box even when the button does not have the input focus |
| BS_GROUPBOX | Creates a rectangle in which other buttons can be grouped. Text associated with this style is displayed in the rectangle's upper-left corner. |
| BS_OWNERDRAW | Creates an owner-drawn button. The framework calls the DrawItem method when a visual aspect of the button has changed. This style must be set when you use the CBitmapButton class. |
| BS_PUSHBUTTON | Creates a command button that sends a BN_CLICKED notification to the owner window when the user clicks the button. |
| BS_RADIOBUTTON | Creates a radio button with two states: BST_CHECKED and BST_UNCHECKED. Radio buttons are usually used in groups, with each group having a maximum of one checked option at a time. Clicking on the button sends a BN_CLICKED notification to the owner window but does not automatically change the state of any button in the group. By default, associated text is displayed to the right of the radio button. To display text to the left of the radio button, use the BS_LEFTTEXT or BS_RIGHTBUTTON style. |
| BS_SPLITBUTTON | Creates a split button. A split button is a command button specific to Windows Vista that contains a button adjacent to a drop-down arrow. When you click the button, the default command is executed. When you click the drop-down arrow, a menu of additional commands appears. |
| BS_USERBUTTON | Obsolete, but provided for compatibility with 16-bit versions of Windows. Win32-based applications should use BS_OWNERDRAW instead. |
