VC2010中實現(xiàn)自定義窗口按鈕控件

1、 VC+ 2010中實現(xiàn)自定義窗口按鈕控件1. 新建一個MFC類使得它繼承與CButton類；2.32.在生成的類中添加變量#pragma once/ CCustomButtonclass CCustomButton : public CButtonDECLARE_DYNAMIC(CCustomButton)public:CCustomButton();virtual CCustomButton();BOOL m_IsPressed;protected:DECLARE_MESSAGE_MAP()public:virtual void DrawItem(LPDRAWITEMSTRUCT /*lp
