Get Text from Cursor position

In a Edit Box, I could use "GetCaretPos()" to get the coordinate (x, y) of
the cursor, but how can I get the Text at the position?

In MFC, there is a funtion "CharFromPos()" to get the item, but there seems
has no corresponding function in Win32 API?

Any suggestion is appreciated

Basically, strings are arrays of characters, in the case of PPC this would
mean TCHAR.
So first get the text of the edit box into a TCHAR array and then simply
access its characters by using an index.

Example:

TCHAR szText[100];
SendMessage(WM_GETTEXT,hwndEdit,(WPARAM)100,(LPARAM)szText);

// get the 5th character
TCHAR c=szText[4];

MFC is just wrapper for Win32, so MFC can't do anything unless Win32
can do it first. We have access to much of the source code for MFC,
which is thus a decent "library" of code (not always easy to follow,
but definitely real and tested). However, I made a _quick_ attempt to
find source for CharFromPos and failed.

My next effort started by looking up GetCaretPos in my copy of MSDN
Library (AKA F1 help), then using "Locate", and then wandering to
"nearby" section for Edit boxes. That got me to EM_CHARFROMPOS.
