VC 6 SDK Listcontrol 控件数据编辑及使用范例

VC6・0SDKListcontrol控件数据编辑2011-11-1318:58:06|分类：默认分类|标签：|字号大中小订阅实现步骤：1.VC6.0新建Win32Application工程文件ListtrlEdit,选择"HelloWorld!"。在About对话框中添加Listcontrol控件ID为：IDC_LIST1，属性修改如下：添加“确认”按钮ID为：IDB_BTOK,勾选Defaultbutton属性

“取消”按钮ID为：IDB_CANCEL“Edit”编辑框，ID为“IDC_EDIT1”，去掉Visible、Border属性对号

将原“OK”按钮改名为“退出”并去掉Defaultbutton属性对号
