If text is selected in a regular textbox, I can use SelStart and SelLength
to get the beginning and ending positions of what is selected.  However,
depending on how the text was selected (ie right-to-left or left-to-right,
the cursor (blinking) can either be at the far right or the far left of the
selected text.

Is there anyway to determine which of these two possibilities the blinking
cursor is located?

Thanks,
Jim
