WordPress 系统的问题
1. 升级到2.1之后，发现WYSIWYG编辑器有点问题，段落前的空格总是没有
2. 用windows live writer不能发布嵌入的图片
code.screen, div.codescreen{
font-family: monospace;
font-size: 1em;
display: block;
padding: 10px;
border: 1px solid #bbb;
background-color: #eee;
color: #000;
overflow: auto;
border-radius: 2.5px;
-moz-border-radius: 2.5px;
margin: 0.5em 2em;
}
Although many people don’t like MFC, sometimes we have to use it. 
This article presents a sample to describe how to implement height adjustment and owner drawing for HeaderControl of ListControl.
Header file:
class CSkinManager; class COwnerDrawHeaderCtrl : public CHeaderCtrl { public: COwnerDrawHeaderCtrl(); protected: virtual void DrawItem(LPDRAWITEMSTRUCT); protected: //{{AFX_MSG(COwnerDrawHeaderCtrl) afx_msg LRESULT OnLayout(WPARAM wParam, LPARAM lParam); afx_msg void OnPaint(); afx_msg BOOL OnEraseBkgnd(CDC* pDC); //}}AFX_MSG DECLARE_MESSAGE_MAP() private: CSkinManager &m_skinManager; };
