C语言的记事本程序

下面是扰世c的记事本小程序，for windows：

加入到工程中，再加上rc资源菜单缓迟肢，用dev c++编译即可实现：

1、C程序：

2、RC资源菜单程序：

#define CM_FILE_SAVEAS9072

#define CM_FILE_EXIT9071

#define CM_FILE_OPEN9070

#define CM_ABOUT9069

MAINMENU MENU

{

POPUP "&File"

{

MENUITEM "&Open...", CM_FILE_OPEN

MENUITEM "Save &As...", CM_FILE_SAVEAS

MENUITEM SEPARATOR

MENUITEM "E&xit", CM_FILE_EXIT

}

POPUP "&Help"

{

MENUITEM "&About", CM_ABOUT

}

}

已经在dev c++调试通过

全实现,程序太长,发不上去,先实现基本的 图形用户界面

import java.awt.event.*

}

})
