Set its fontstyle to FontStyle.Bold Xor FontStyle.Underline

[.paul.]

RichTextBox1.SelectionFont = New Font(RichTextBox1.SelectionFont.Name, RichTextBox1.SelectionFont.Size, FontStyle.Bold Or FontStyle.Underline)

I'm afraid neither suggestion so far is quite right. To apply a style to a Font without losing any current styles you need to perform a bitwise Or with the current style and the new style. That means your code should be:

myRichTextBox.SelectionFont = New Font(myRichTextBox.SelectionFont, myRichTextBox.SelectionFont.Style Or FontStyle.Bold Or FontStyle.Underline

That will create a new Font using the existing Font as a basis and set its Style to a combination of the current style, Bold and Underline. By including the current Style in the combination you will not lose any other styles that are currently applied. If you set the style using Bold and Underline only then you would lose any other styles.

Having said that, if you actually DO want to lose any other styles then you would not include the current style in the combination.

I should also point out that you'd only use Xor when toggling an existing style. For instance, this code:

myRichTextBox.SelectionFont = New Font(myRichTextBox.SelectionFont, myRichTextBox.SelectionFont.Style Xor FontStyle.Bold

will turn Bold on if it's currently off and it will turn it off if it's currently on.
