artdialog 如何增加窗体滚动条

设置d出层的宽高，渣橡如果d出层的内容超出了可显示区域，自动会出现滚动条。

当然这是纯粹使用浏览器的滚动条机制：尘梁大

参照派竖css中的overflow属性 http://www.w3school.com.cn/cssref/pr_pos_overflow.asp

void CXXDlg::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)

在窗口界面编辑器歼猜里拖上去画出来就行了。

如果要纯代码生成的话，就在OnInitDialog里：

比如构造一个列表扰戚框CListBox

那么在全局区或窗氏李型体类里添加CListBox对象为成员变量。

CListBox

m_listbox

然后调用Create方法

mlistbox.Create()具体参数怎么写看MSDN或百度
