EM_SETSEL message
Applies to: desktop apps only
Selects a range of characters in an edit control. You can send this message to either an edit control or a rich edit control.
Parameters
- wParam
-
The starting character position of the selection.
- lParam
-
The ending character position of the selection.
Return value
This message does not return a value.
Remarks
The start value can be greater than the end value. The lower of the two values specifies the character position of the first character in the selection. The higher value specifies the position of the first character beyond the selection.
The start value is the anchor point of the selection, and the end value is the active end. If the user uses the SHIFT key to adjust the size of the selection, the active end can move but the anchor point remains the same.
If the start is 0 and the end is –1, all the text in the edit control is selected. If the start is –1, any current selection is deselected.
Edit controls: The control displays a flashing caret at the end position regardless of the relative values of start and end.
Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.
If the edit control has the ES_NOHIDESEL style, the selected text is highlighted regardless of whether the control has focus. Without the ES_NOHIDESEL style, the selected text is highlighted only when the edit control has the focus.
