I am also working on this with a near-term deadline.  If we could find
the rtf text (including codes) we could insert text quite easily. 
However, RichEdit.Text is just the text, NOT the rtf codes.  I don't
know, but if you find out, PLEASE let me know, too!  Thanks.

Travis,

Are super/subscript supported in WordPad? I don't believe so... And
since WordPad is just TRichEdit, anything not supported in WordPad
isn't supported in TRichEdit.

Ken,

Hello.  I don't recall whether or not WordPad supports super- or sub-scripts.
I rarely use it...except for the text files that are "too large for Notepad".
:-)

However, I believe you're wrong about it not being supported in TRichEdit just
because it's not supported in WordPad.  In MSDN Library (the one with Visual
Studio 6.0), I was able to find a list of supported RTF, or rich text format,
codes.  I think you'd be surprised at the number of things you can do with
it.  I was.  Anyway, within the codes are two:  sub for subscript, and super
for superscript.

The only problem is, it doesn't mention how to go about using the codes.  I
have been able to pick up a bit here and there, but most of it is fragmented
and vague.  Also, I've finally found a way...rather complicated...to make
superscripts and subscripts within a TRichEdit control.  I still have a long
ways to go, though, and it's far from user-friendly.  That's why I'm still
hoping for someone to come up with a simpler method.  (I go into more detail
in response to another posting.)

Another thing is this:  the VB RTF control supports superscript and
subscript.  Here's a chunk from the help file in the MSDN Library on the VB
RTF control:

     The RichTextBox control provides a number of properties you can use to
     apply formatting to any portion of text within the control. To change the
     formatting of text, it must first be selected. Only selected text can be
     assigned character and paragraph formatting. Using these properties, you
     can make text bold or italic, change the color, and create superscripts
     and subscripts. You can also adjust paragraph formatting by setting both
     left and right indents, as well as hanging indents.

So, as you can see, it is supported in one language.  And, I must say, it
appears much easier to implement in VB than in Delphi.  (This doesn't happen
too often, in my humble experience, but it does happen.)

Anyway, I hope that someone can still help me (and, most likely, others) in
finding a solution.

Thanks for the response,

Travis

Hi Alan, and thanks for the response.

Yes, I've also discovered exactly what you're saying.  I have the codes that I
need, but I don't know how to insert (or remove) them.  As you've pointed out,
we seem to only be able to access the text, and nothing more.  I think if
someone can give us a clue as to how one inserts and manipulates the codes,
then it would help a lot.  Is there anyone out there...?  :-)

For now, what I've done is to use the EM_GETCHARFORMAT and EM_SETCHARFORMAT
messages along with the CHARFORMAT structure.  It's a bit messy right now, and
only serves to imitate the actual sub- and super-scripting behavior.  I don't
like to have to do it this way, but it's all I have right now.

I don't know if this "methodology" will help you out, but it might serve until
we find out how to actually insert the codes.  Or, it could end up being too
much trouble.  :-)

Anyway, I'll be sure to say something to you if I find out anything more.

Thanks,

Travis

Its not very elegant, but what you can do is use richedit.lines.savetostream
to get the data in a memorystream. Then insert the codes you want in the
appropriate places - they are just plain text codes - and use
richedit.lines.loadfromstream to update the control.

Hi

Have a look at the EM_SETCHARFORMAT message and the CHARFORMAT structure
(dwMask) in the Win32 help file - it may be what you are looking for.

Hope this helps.

Bruce,

Thank you for your input.  As far as using the actual RTF codes, this seems to
be one of the better suggested solutions.  Many of the others are what I
consider "work-arounds".  I mean, the will do the job, and the text will appear
properly to the user, but if you open up the RTF data, there will be no signs of
/super or /sub RTF codes.

Thanks again,

Travis

Paul,

Thanks for your input.  I have managed to find the message and structure that
you mentioned.  It appears as though that's one of the only ways to have
superscript or subscript in a Rich Edit control.  However, I do consider this
only a "work-around".  I mean, it will do the job, and the text will appear
properly to the user, but if you open up the RTF data, there will be no signs
of /super or /sub RTF codes....only signs of the RTF codes that have to do
with the character formats.

A great solution, I think, would be a way to insert and remove RTF codes, and
not have to use EM_SETCHARFORMAT and CHARFORMAT.  But, for the time being,
this appears to be one of the only solutions.  There is also a proposed
solution from Bruce in this thread that I haven't tried yet.  It looks good,
in theory, and I intend to try it out ASAP.

Thanks again for your time,

Travis

Building on Bruce's suggestion:

Why not derive a new component from TRichEdit, with your customized
procedures.
My suggestion would be to have a TStringList structure that holds the
unformatted RTF data, and store the data in a memorystream for the RichEdit
to load from.

It's just a suggestion,... I haven't tried it before.

Wordpad kan show superscript, eg. created by WORD.
