CListCtrl::GetStringWidth

Visual Studio 2012

Determines the minimum column width necessary to display all of a given string.

Copy 
int GetStringWidth( 
   LPCTSTR lpsz  
) const;
lpsz

Address of a null-terminated string whose width is to be determined.

The width, in pixels, of the string pointed to by lpsz.

The returned width takes into account the control's current font and column margins, but not the width of a small icon.

C++
Copy 
		CString strColumn;
		int nWidth;

		// Insert six columns in the list view control. Make the width of 
		// the column be the width of the column header plus 50%. 
		for (int i = 0; i < 6; i++)
		{
			strColumn.Format(_T("column %d"), i);
			nWidth = 3*m_myListCtrl.GetStringWidth(strColumn)/2;
			m_myListCtrl.InsertColumn(i, strColumn, LVCFMT_LEFT, nWidth);
		}
