Thanks for your help, Sergey.

I have one additional question: When I search and find the tag that has

to be replaced, it is automatically selected in the RichViewEditor. Now I

can determine the font color easily. Isn't there a way to insert the new

text from a stream and thenselect this inserted text. This way I could assign

the color to the selected text and wouldn't have to use another invisible

RichViewEditor.

The way I could image to do it would be:

- search the tag

- determine the color

- delete the tag

- save the caret position (GetSelectionBounds)

- insert the new text from stream. The caret is positioned at the end of

the inserted text afterwards, isn't it?

- select text from here to formerly saved caret position (i.e. beginning

of inserted text)

- assign color to this selection

But I don't know if the item numbering changes when I call InsertRVFFromStreamEd.

If it does, I cannot store the caret position before inserting the new text

and thus I would now where the start of the inserted text would be.

If - on the other hand - the item numbering stays accurate after inserting

the new text, I would do it as described above.

I'm a little anxious of using another invisible RichViewEditor and RVStyle

component, because my application is using many ressources which can cause

problems under Windows 98. I wouldn't like to need and use even more ressources.

What would you suggest?

Regards,

Christian
