The GetCaretPos function copies the caret's position, in client coordinates, to the
specified
POINT structure.
BOOL GetCaretPos(
LPPOINT lpPoint // address of structure to receive coordinates
);
Parameters
lpPoint
Points to the POINT structure that is to receive the client coordinates of the caret.

Finding the Line Number of the Caret Position
---------------------------------------------
Perform the following two steps:
1. Send the EM_GETSEL message to the edit control. The high-order word
of the return value is the character position of the caret relative
to the first character in the control.
2. Send the EM_LINEFROMCHAR message to the edit control and specify the
value returned from step 1 as wParam. Add 1 to the return value to
get the line number of the caret position because Windows numbers
the lines starting at zero.
Finding the Column Number of the Caret Position
-----------------------------------------------
Perform the following three steps:
1. Send the EM_GETSEL message to the edit control. The high-order word
of the return value is the character position of the caret relative
to the first character in the control.
2. Send the EM_LINEINDEX message with wParam set to -1. The value
returned is the count of characters that precede the first
character in the line containing the caret.
3. Subtract the value returned in step 2 from the value in step 1 and
add 1 because Windows numbers the columns starting at zero. This
result is the column number of the caret position.
