turn test containing multiple fonts to bold

[pettyprogrammer]

I hav used the following text to turn text bold. but it doesnt work when i select text with multiple fonts

Dim doc As frmDocument = Me.ActiveMdiChild
        On Error Resume Next
        If doc.Text1.Focused Then
            If doc.Text1.SelectionLength > 0 Then
                doc.Text1.SelectionFont = New System.Drawing.Font(doc.Text1.SelectionFont, doc.Text1.SelectionFont.Style Xor FontStyle.Italic)
            End If
        End IF

Text1 is rtb on child form.

When this happens you can go through the selected text selecting char-by-char and modify each chars font.
See for example post 2: Change the format od the Font when writing to a RTF document using vb.net 2005
