I need help finding the part of the text that is on screen.
I know how to find the Selected Text EVERYTHING and to find
text in a search and to tell the twip coordinates of the box.  What I need most is the character number which
appears in the upper left of the box, length or
character postion of the last text showing would be a
plus.              ;-)   Dave McAn

Dim lngPos As Long
Dim lngResultFirst As Long
Dim lngLine As Long
Dim lngChar As Long
Dim strHex As String

    lngPos = 0  'low bit for X coord, 0 high bit for Y coord
    lngResultFirst = SendMessage(RichTextBox1.hwnd, EM_CHARFROMPOS, 0, lngPos)

lngChar = lngResultFirst And (2 ^ 16 - 1)
strHex = Right$(String(8, "0") & Hex$(lngResultFirst), 8)
lngLine = CLng("&H" & Left$(strHex, 4))


the line is relative the top of the control

One thing I noticed is that the vertical scrollbar must be turned on for this to work.

Thanks, but boy do I have my work cut out for me.  I still need
the horizontal length, and to be able to correlate with another
RTF control with different line lengths, and of course the box
length can vary with the resizable form.  Any other suggestions?
