Setting the font for different lines in a richTextBox

Question

I am setting up a richTextBox that can be saved as a file and also printed if the user desires. My code for this richTextBox so far is. Form2.richTextBox1.Font = new System.Drawing.Font(Microsoft Sans Serif 14F); Form2.richTextBox1.Text +=  
  + textBox1.Text +  
; //address Form2.richTextBox1.Font = new System.Drawing.Font(Microsoft Sans Serif 10F); Form2.richTextBox1.Text +=   + textBox2.Text +  
; //citystatezip It sets the font to 14 then writes the line then sets the entire box to the 10 font. What is the code for the first and third lines so the fonts are different. Or is this even possible. Thanks for any help in advance!! Frank

Indeed modifying the RichTextBox.Font property will modify the font for the entire text. Try it like this (i'll replace richTextBox1 with rtb1 for covenience): //write the text first rtb1.Text+=...; rtb1.Select(rtb1.Text.IndexOf(rtb1.Lines[0]0)rtb1.Lines[0].Length);//will select only the first line of text rtb1.SelectionFont=new System.Drawing.Font(Palatino Linotype15);//use whatever font you want Then add as more text as you want and select the desired line like above replacing Lines[0] with Lines[index] where index is what line number you want (notice that because RichTextBox.Lines is a string array the line numbers begin from 0).
