EM_SETSEL

An application sends an EM_SETSEL message to select a range of characters in an edit control.

EM_SETSEL 
wParam = (WPARAM) (INT) nStart;    // starting position 
lParam = (LPARAM) (INT) nEnd;      // ending position 
 

Parameters

nStart

Value of wParam. Specifies the starting character position of the selection.

nEnd

Specifies the ending character position of the selection.

Return Values

This message does not return a value.

Remarks

In a rich edit control, if the selection is not entirely contained in the first 64K, use the message EM_EXSETSEL.

If the nStart parameter is 0 and the nEnd parameter is –1, all the text in the edit control is selected. If nStart is –1, any current selection is removed. The caret is placed at the end of the selection indicated by the greater of the two values nEnd and nStart.
