		GetTextMetrics (hdc, &tm) ;
		cxChar = tm.tmAveCharWidth ;
		cxCaps = (tm.tmPitchAndFamily & 1 ? 3 : 2) * cxChar / 2 ;
		cyChar = tm.tmHeight + tm.tmExternalLeading ;

可否

// IDC_STATIC1为静态文本控件，下面的代码主要是使用GetTextExtentPoint32函数来得到字符串的CSize，希望对你有帮助
CString strText(_T(""));
	CWnd* pWnd = GetDlgItem(IDC_STATIC1);
	pWnd->GetWindowText(strText);
	ASSERT(pWnd);
	CDC* pDC = pWnd->GetDC();
	CSize size;
	int count = strText.GetLength();
	GetTextExtentPoint32(pDC->GetSafeHdc(), strText, count, &size);
	pDC->DeleteDC();
	int nWidth = size.cx / count;
	
	int nIndex = (size.cx/2)/nWidth;
	strText = strText.Mid(0, nIndex);
	AfxMessageBox(strText);
