Caret postioning affected by glyphs usage in Internet explorer in designmode

Question

Hi,

I try to use internet explorer as Html editor in designmode from Delphi. I use the Mshtml and SHDocVw units and editing goes fine. I also display some glyphs like the 'special characters' option in Word (e.g. paragraph: ¶). Now there appears to be a difference between caret positioning between Hiding Glyphs or Showing Glyphs.

1) Hidden glyphs

When pressing <End> key on 'Sample Text', the Caret is positioned directly after the last character 't': Sample Text|

When I now type the <1> key, the html result is as I expected:

<p>Sample Text1</p> 

2) Showing glyphs

When pressing <End> key on 'Sample Text', the Caret is not directly positioned after the last character, but after the Glyph : Sample Text¶ |

When I now type the <2> key, the html result is

<p>Sample Text</p>2 

So the '2' ends up outside the paragraph.

I also checked what happens if I hide the glyphs before pressing a non-system key:

3) Showing glyphs and hiding them afterwards

First show glyphs, press <End> key on 'Sample Text', hide the glyphs, the Caret is still not directly positioned after the last character, there appears some space in the screen (no real character/element in the html-source however): Sample Text | When I now type the <3> key, the html result is

<p>Sample Text</p>3 

So the '3' still ends up outside the paragraph.

The same problems exist with keys like <Home> and the arrow keys.

How can I prevent this? Is there a way to prevent caret placement after the glyph, or change it to the last character of the paragraph?

Kind regards,

Bert

You can try Regular expression

Thank you for your answer,

Indeed I could use that, but if there's an other way by having more control over Caret placement, I would prefer that sollution.
