CSize GetTextExtent( LPCTSTR lpszString, int nCount ) const;
CSize GetTextExtent( const CString& str ) const;
Return Value
The dimensions of the string (in logical units) in a CSize object.
Parameters
lpszString
Points to a string of characters. You can also pass a CString object for this parameter.
nCount
Specifies the number of characters in the string.
str
A CString object that contains the specified characters.
Remarks
Call this member function to compute the width and height of a line of text using the current font to determine the dimensions. The information is retrieved from m_hAttribDC, the attribute device context.
The current clipping region does not affect the width and height returned by GetTextExtent.
Since some devices do not place characters in regular cell arrays (that is, they carry out kerning), the sum of the extents of the characters in a string may not be equal to the extent of the string.
