In the course of your development, you might find that you need to change the font style of a control to somthing like bold or italic.

Upon investigation, you find that each control has a Font property, that additionally has a boolean Bold property. So you would attempt the following:

   1: //

   2: // Set the font to bold

   3: //

   4: txtName.Font.Bold = true;

This unfortunately, would fail. Why? Because the Bold property of a font is read only.

To change the font to bold, you actually need to create a new font, and specify that the new font be created with the style bold. Like so

   1: //

   2: // Change the font to bold, using the existing font

   3: //

   4: txtName.Font = new Font(txtName.Font, FontStyle.Bold);

The same thing would apply for italics.

   1: //

   2: // Change the font to italic, using the existing font

   3: //

   4: txtName.Font = new Font(txtName.Font, FontStyle.Italic);

An intersting thing to note -- you can also combine the multiple styles. Like so

   1: //

   2: // Change the font to bold, strikeout & italic , using the existing font

   3: //

   4: txtName.Font = new Font(txtName.Font, FontStyle.Italic | FontStyle.Strikeout | FontStyle.Bold);
