Hi all.

I was researching how to work with Unicode in a textbox and ran into one piece of code involving the function, SendMessageWLng(), as in:
SendMessageWLng(RTB.hWnd, EM_GETTEXTLENGTHEX, VarPtr(gtlUnicode), 0)
The author did not post his declarations or constants.

Problem is, I cannot find any reference to this function on MSDN, any of the API refs, or ref programs.

This must be a function held in great reverence in a Masonic temple attic somewhere!

Is it the Win API or some other? If not, can someone steer me to the alternate universe where it exists, cause I really need it!
