Visual Basic: RichTextBox Control
SelCharOffset Property Example
This example uses a scroll bar to move selected text above or below the baseline. The minimum and maximum amount of offset is established by the font size of the text within the RichTextBox control. To try this example, put a RichTextBox control and a VScrollBar control on a form. Paste this code into the Change event of the VScrollBar control. Then run the example.
Private Sub VScroll1_Change ()
VScroll1.Max = RichTextBox1.SelFontSize
VScroll1.Min = -(VScroll1.Max)
RichTextBox1.SelCharOffset = VScroll1.Value
End Sub
