Parameters lpszCaption Specifies the button control's text.dwStyle Specifies the button control's style. Apply any combination of button styles to the button.rect Specifies the button control's size and position. It can be either a CRect object or a RECT structure.pParentWnd Specifies the button control's parent window, usually a CDialog. It must not be NULL.nID Specifies the button control's ID. Button StylesBS_3STATE Same as a check box, except that the box can be dimmed as well as checked. The dimmed state typically is used to show that a check box has been disabled.BS_AUTO3STATE Same as a three-state check box, except that the box changes its state when the user selects it.BS_AUTOCHECKBOX Same as a check box, except that a check appears in the check box when the user selects the box; the check disappears the next time the user selects the box.BS_AUTORADIOBUTTON Same as a radio button, except that when the user selects it, the button automatically highlights itself and removes the selection from any other radio buttons with the same style in the same group.BS_BITMAP Specifies that the button displays a bitmap. BS_BOTTOM Places text at the bottom of the button rectangle. BS_CENTER Centers text horizontally in the button rectangle. BS_CHECKBOX Creates a small square that has text displayed to its right (unless this style is combined with the BS_LEFTTEXT style).BS_DEFPUSHBUTTON Creates a button that has a heavy black border. The user can select this button by pressing the ENTER key. This style enables the user to quickly select the most likely option (the default option).BS_FLAT Specifies that the button is two-dimensional; it does not use the default shading to create a 3-D image. BS_GROUPBOX Creates a rectangle in which other buttons can be grouped. Any text associated with this style is displayed in the rectangle's upper-left corner.BS_ICON Specifies that the button displays an icon. BS_LEFT Left aligns the text in the button rectangle. However, if the button is a check box or radio button that does not have the BS_RIGHTBUTTON style, the text is left aligned on the right side of the check box or radio button. BS_LEFTTEXT When combined with a radio-button or check-box style, the text appears on the left side of the radio button or check box.BS_MULTILINE Wraps the button text to multiple lines if the text string is too long to fit on a single line in the button rectangle. BS_NOTIFY Enables a button to send BN_DBLCLK, BN_KILLFOCUS, and BN_SETFOCUS notification messages to its parent window. Note that buttons send the BN_CLICKED notification message regardless of whether it has this style. BS_OWNERDRAW Creates an owner-drawn button. The framework calls the DrawItem member function when a visual aspect of the button has changed. This style must be set when using the CBitmapButton class.BS_PUSHBUTTON Creates a pushbutton that posts a WM_COMMAND message to the owner window when the user selects the button.BS_PUSHLIKE Makes a button (such as a check box, three-state check box, or radio button) look and act like a push button. The button looks raised when it isn't pushed or checked, and sunken when it is pushed or checked. BS_RADIOBUTTON Creates a small circle that has text displayed to its right (unless this style is combined with the BS_LEFTTEXT style). Radio buttons are usually used in groups of related, but mutually exclusive, choices.BS_RIGHT Right aligns the text in the button rectangle. However, if the button is a check box or radio button that does not have the BS_RIGHTBUTTON style, the text is right aligned on the right side of the check box or radio button. BS_RIGHTBUTTON Positions a radio button's circle or a check box's square on the right side of the button rectangle. Same as the BS_LEFTTEXT style. BS_TEXT Specifies that the button displays text. BS_TOP Places text at the top of the button rectangle. BS_USERBUTTON Obsolete, but provided for compatibility with 16-bit versions of Windows. Win32-based applications should use BS_OWNERDRAW instead. BS_VCENTER Places text in the middle (vertically) of the button rectangle.

const RECT& rect 就是你的按钮位置！
在Dlialog的OnInitDialog的函数中添加下面代码
m_button.Create(_T("MyButton"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, CRect( 0,0, 100, 25), this, ID_MYBUTTON );
要处理点击按钮的事件，要加下面的代码
WM_MYBUTTON是你自己定义的一个宏，在resource。h文件里面定义
#define WM_MYBUTTON WM_USER + 1在h文件中添加afx_msg void OnBnClickedMyButton();在cpp文件的BEGIN_MESSAGE_MAP和END_MESSAGE_MAP中间添加
ON_BN_CLICKED(ID_MYBUTTON, OnBnClickedMyButton);然后在下面实现
void CMyDialog::OnBnClickedMyButton()
{
AfxMessageBox(_T("Clicked"));
}
