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. Pointer to a 32-bit value that receives the starting position of the selection. This parameter can be NULL.

lpdwEnd

Value of lParam. Pointer 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.
