AfxMessageBox与MessageBox的区别

int  AfxMessageBox(
LPCTSTR lpszText,
UINT nType = MB_OK,
UINT nIDHelp = 0 );

lpszText Points to a CString object or null-terminated string containing the message to be displayed in the message box. nType The style of the message box. Apply any of the message-box styles to the box.   nIDHelp The Help-context ID for the message; 0 indicates the application’s default Help context will be used.

 

int  MessageBox(
HWND hWnd,
LPCTSTR lpText,
LPCTSTR lpCaption,
UINT uType);

hWnd [in] Handle to the owner window of the message box to be created. If this parameter is NULL, the message box has no owner window. lpText [in] Long pointer to a null-terminated string that contains the message to be displayed. lpCaption [in] Long pointer to a null-terminated string used for the dialog box title. If this parameter is NULL, the default title “Error” is used. uType [in] Specifies a set of bit flags that determine the contents and behavior of the dialog box. This parameter can be a combination of flags from the following groups of flags.
 

1.MessageBox是CWnd的类成员函数。  
  AfxMessageBox是全局API函数。

2.如果使用的是MFC应用程序，两者都可以使用，但用AfxMessageBox更方便。
  如果创建的是SDK，则只能用MessageBox。
  AfxMessageBox是AFX小组为了取代API采取的一种方法。   

3.MessageBox比AfxMessageBox灵活，体现在参数上。因为AfxMessageBox是一个全局函数所以不需要对应一个窗类，同时也不能控制消息框的标题。而MessageBox可以通过参数写明标题内容。
