<br>内容：时间都不多阿，我也没有美国时间。:)<BR>给你一个例子，从msdn上拷下来的。他是在CDialog的OnCtlColor里改变一个控件的颜色。你把控见id改一下就行了。<BR><BR>HBRUSH CZilchDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <BR>{<BR>&nbsp;&nbsp; // Call the base class implementation first! Otherwise, it may<BR>&nbsp;&nbsp; // undo what we're trying to accomplish here.<BR>&nbsp;&nbsp; HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<BR><BR>&nbsp;&nbsp; // Are we painting the IDC_MYSTATIC control? We can use<BR>&nbsp;&nbsp; // CWnd::GetDlgCtrlID() to perform the most efficient test.<BR>&nbsp;&nbsp; if (pWnd-&gt;GetDlgCtrlID() == IDC_MYSTATIC)<BR>&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Set the text color to red<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pDC-&gt;SetTextColor(RGB(255, 0, 0));<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Set the background mode for text to transparent <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// so background will show thru.<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pDC-&gt;SetBkMode(TRANSPARENT);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Return handle to our CBrush object<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;hbr = m_brush;<BR>&nbsp;&nbsp; }<BR><BR>&nbsp;&nbsp; return hbr;<BR>}<BR>

<br>内容：至于SetFont，<BR>假设CFont* pFont = CreatFont(..);<BR><BR>GetDlgItem(IDC_BUTTON)-&gt;SetFont(pFont)。<BR><BR>Font我搞得不多。:)<BR>2003-11-27 17:09:09
