计算多行字符串的文本范围

问题描述

大家好，

我有一个多行字符串需要在具有固定宽度和可变高度的矩形区域中绘制.在矩形中绘制字符串时，如果线的长度超过区域的宽度，则超​​出的部分将放入新的线中.

我需要计算文本区域的边界矩形的高度.我该怎么做?

我确实检查了CDC的GetTextExtend ...()函数，但它们只允许获取单行字符串的范围.

请在这方面帮助我.

在此先感谢.

Hi All,

I have a multi-line string need to be drawn in a rectangular area which has fixed-width and variable height. As the string being drawn in the rectangle, if a line''s length exceeds the area''s width, the exceeding part will be put in to a new line.

What I need is to calculate height of boundary rectangle of text area. How can i do it?

I did check GetTextExtend...() functions of CDC, but they allow to get extent of SINGLE line string only.

Please help me in this regard.

Thanks in Advance.
Quy
