Height of Text

Introduction

This is a handy little function for getting the height of text. 

Overview

I have read many articles and asked lots of questions before I found the functions in the dot net library that would help me to achieve this task.

This is also my very first Code Project article. This site has helped me solve MANY problems and I hope that this piece of code helps someone out.

The Code

<BR>  /// <summary><BR>  /// This method will return the height of the string passed in.<BR>  /// </summary><BR>  /// <param name="strMeasureString">The string to measure</param><BR>  /// <param name="stringFont">The font to measure by</param><BR>  /// <param name="nWidth">The max width the string can be [Width of the text box usually ;)]</param><BR>  /// <param name="hwnd">Handle to your form so I can get the graphics object</param>  <BR>  /// <returns>The height of the string as a int</returns> <FONT color=#0000ff size=2><P> </P><P>public</FONT><FONT size=2> </FONT><FONT color=#0000ff size=2>int</FONT><FONT size=2> GetStringHeight(</FONT><FONT color=#0000ff size=2>string</FONT><FONT size=2> strMeasureString, System.Drawing.Font stringFont, </FONT><FONT color=#0000ff size=2>int</FONT><FONT size=2> nWidth,System.IntPtr hwnd) </P><P>{</P><P></FONT><FONT color=#0000ff size=2>	using</FONT><FONT size=2> (System.Drawing.Graphics g = System.Drawing.Graphics.FromHwnd(hwnd))</P><P>	{</P><P></FONT><FONT color=#0000ff size=2>		return</FONT><FONT size=2> (</FONT><FONT color=#0000ff size=2>int</FONT><FONT size=2>)g.MeasureString(strMeasureString, stringFont, nWidth).Height; </P><P>	}</P><P>}</P></FONT>

(Thanks for the advice Micheal)

Its pretty straightforward and it creates some pretty cool effects if you use it with the 'Text Changed' event of a text box. Tie that to the 'Resize' event and you can have a form the grows and shrinks as the user is typing in text.
