Enable Fields in RichTextBox

[Bertrand P.]

I want use a RichTextBox to allow users to edit and
modify complex report.
I need to insert at runtime many optional fields wich
comes from a database.
I have think "well I will use the rtf command \field !"
but this command does work correctly.
If you load one file wich contains \field commands like
described in rtf syntax, the RichTextBox
delete theses commands and replace it whith the default
values
AND I did not can edit the fields !

NOT : All versions of the RichEdit Control from Microsoft
run like that (in previous versions of VB or VC++)

To reproduce it, insert RichTextBox, implement Load
function to load the File,
implement one function to get the Rtf code in the control
after the Load.

Sample of rtf file :
{\rtf1\ansi\ans icpg1252\deff0\ deflang1036{\fo nttbl{\f0
\fnil\fcharset0 Microsoft Sans Serif;}}
\viewkind4\uc1\ pard\f0\fs17 Test of field in RTF
controls\par
The two next lines contains two field like in MDSN rtf
definition\par
{\field {\*\fldinst AUTHOR \\*MERGEFORMAT }{\fldrslt Joe
Smith}}\par
{\field{\*\fldi nst time \\@ "h:mm AM/PM"}{\fldrslt 8:12
AM}}\par
End of fields\par
end of text\par
\par
}

Does anibody have a solution to enable the \field in the
control !?
Thank's
