Length of a Richtext printed string

I need to determine the length of a Richtext string, but I only want to count the characters that actually print.  

Using the Len() function, I can determine the length of a Richtext string, but the calculation includes a long list of non-printing Richtext formatting characters (e.g. "{\rtf1\ansi\ansicpg-1\...").  Generally there appears to be 115 non-printing characters, but I've also seen 126.  I assume this is a dynamic value based on the type and amount of formatting that the user applies to the text.

Is there a way to avoid counting the formatting characters when calculating the string length?

Thanks, T.C.

Well if the formatting is forseeable, then probably you can apply some filter before counting the len.eg

presume strtext = "{\rtf1\ansi\ansicpg-1\xxx}"

assuming xxx is the len you want to count then wat you can do is

For i = 1 to len(strtext)
strTemp = right(strtext,i)
if strtemp = "\" then
Strlength = len(strTemp)
exit for
end if
next

You can alter the filter to the pattern that you need. Hope it explains.

doesn't Len(Richtextbox1.text) do the trick ??
because there are two options for the text
Richtextbox1.Text 'to get the plaintext
Richtextbox1.TextRtf 'to get the RtfText
