<tr><td><p>
</Br>
我看过好多关于创建对话框、组合框等等使用MS SANS SERIF的例子，自己也做过多次。如： m_font.CreatePointFont (80, _T("MS Sans Serif")); 或 m_font.Create (-8, ....., _T("MS Sans Serif")); 那么想问一下：1）该字体是否在所有的版本中都能实现（包括国际版本） 2）在控制面板上有没有更好的字体代替“SYSTEM”字体？如果有人这样做了，那又是怎样设置字体大小等相关设置的？我希望有一个彻底的方法来选择组合框等的字体。<Br>
</Br>
1)有件事情我做过,在我所有的程序界面中都改变了字体.消息框来显示用户选择的字体. 菜单,工具条以及其他控件的字体都随用户意愿改变.但在对话框中最好还是用对话框编辑器, 其基本字体都是MS SANS SERIF,所以我也以这种字体来作为所有的用户界面. 以下为我所做的代码:<Br>

// here's the font I use:<Br>
SystemParametersInfo( SPI_GETNONCLIENTMETRICS, 0, &ncm, 0);<Br>
m_fntUI.CreateFontIndirect(&ncm.lfMessageFont);<Br>

// here's the code to change the font for a wnd and all it's children, and<Br>
resize the controls appropriately<Br>
