EM_GETSEL
An
application sends an EM_GETSEL message to get the starting and ending character
positions of the current selection in an edit control.
EM_GETSEL
wParam = (WPARAM) (LPDWORD) lpdwStart; // receives
starting position
lParam = (LPARAM) (LPDWORD) lpdwEnd; // receives ending position
Parameters
lpdwStart
Value of wParam.
Points to a 32-bit value that receives the starting position of the selection.
This parameter can be NULL.
lpdwEnd
Value of lParam.
Points to a 32-bit value that receives the position of the first nonselected
character after the end of the selection. This parameter can be NULL.
Return Values
The return
value is a zero-based 32-bit value with the starting position of the selection
in the low-order word and the position of the first character after the last
selected character in the high-order word. If either of these values exceeds
65, 535, the return value is -1.
Remarks
In a rich
edit control, if the selection is not entirely contained in the first 64K, use
the message EM_EXGETSEL.
