// Summary:
//     CXTFlatComboBox is a CComboBox derived class. The CXTFlatComboBox class
//     can easily give your application's standard CComboBox control the Flat
//     Look that is seen in many of the Microsoft(r) Office(tm) products.
// Remarks:
//     To use the control, use Class Wizard to add the CComboBox member variable (
//     Class Wizard -> Member Variables Tab -> Add Variable) and rename CComboBox
//     to CXTFlatComboBox.

//===========================================================================
// Summary:
//     CXTEdit is a CEdit derived class. The CXTEdit class provides the functionality
//     of a Windows edit control. An edit control is a rectangular child window
//     in which the user can enter text.
// Remarks:
//     You can create an edit control either from a dialog template or directly
//     in your code. In both cases, first call the constructor CXTEdit to construct
//     the CXTEdit object, then call the Create member function to create the
//     Windows edit control and attach it to the CXTEdit object.
//
//     Construction can be a one-step process in a class derived from CXTEdit.
//     Write a constructor for the derived class and call Create from within
//     the constructor.
//
//     CXTEdit inherits significant functionality from CWnd. To set and retrieve
//     text from a CXTEdit object, use the CWnd member functions SetWindowText
//     and GetWindowText, which either set or get the entire contents of an edit control
//     even if it is a multiline control. Also, if an edit control is multiline,
//     get and set part of the control's text by calling the CXTEdit member
//     functions GetLine, SetSel, GetSel, and ReplaceSel.
//
//     If you want to handle Windows notification messages sent by an edit
//     control to its parent (usually a class derived from CDialog), add a
//     message-map entry and message-handler member function to the parent
//     class for each message.
//
//     Each message-map entry takes the following form:
//
// <code>
// ON_Notification(id, memberFxn)
// </code>
//
//          where 'id' specifies the child window ID of the edit control sending the
//          notification, and 'memberFxn' is the name of the parent member function
//          you have written to handle the notification.
//
//          The parent's function prototype is as follows:
//
// <code>
// afx_msg void memberFxn();
// </code>
//
//          Following is a list of potential message-map entries and a description
//          of the cases in which they would be sent to the parent:
//
//        * <b>ON_EN_CHANGE</b> The user has taken an action that may have altered
//          text in an edit control. Unlike the EN_UPDATE notification message,
//          this notification message is sent after Windows updates the display.
//        * <b>ON_EN_ERRSPACE</b> The edit control cannot allocate enough memory
//          to meet a specific request.
//        * <b>ON_EN_HSCROLL</b> The user clicks an edit control's horizontal scroll
//          bar. The parent window is notified before the screen is updated.
//        * <b>ON_EN_KILLFOCUS</b> The edit control loses the input focus.
//        * <b>ON_EN_MAXTEXT</b> The current insertion has exceeded the specified
//          number of characters for the edit control and has been truncated.
//          Also sent when an edit control does not have the ES_AUTOHSCROLL
//          style and the number of characters to be inserted would exceed the
//          width of the edit control. Also sent when an edit control does not
//          have the ES_AUTOVSCROLL style and the total number of lines resulting
//          from a text insertion would exceed the height of the edit control.
//        * <b>ON_EN_SETFOCUS</b> Sent when an edit control receives the input focus.
//        * <b>ON_EN_UPDATE</b> The edit control is about to display altered text.
//          Sent after the control has formatted the text but before it screens
//          the text so that the window size can be altered, if necessary.
//        * <b>ON_EN_VSCROLL</b> The user clicks an edit control's vertical scroll
//          bar. The parent window is notified before the screen is updated.
//
//     If you create a CXTEdit object within a dialog box, the CXTEdit object
//     is automatically destroyed when the user closes the dialog box.
//
//     If you create a CXTEdit object from a dialog resource using the dialog
//     editor, the CXTEdit object is automatically destroyed when the user
//     closes the dialog box.
//
//     If you create a CXTEdit object within a window, you may also need to
//     destroy it. If you create the CXTEdit object on the stack, it is destroyed
//     automatically. If you create the CXTEdit object on the heap by using
//     the new function, you must call delete on the object to destroy it when
//     the user terminates the Windows edit control. If you allocate any memory
//     in the CXTEdit object, override the CXTEdit destructor to dispose of
//     the allocations.
