Function Reference

_GUICtrlEditSetSel

Selects a range of characters in an edit control.

#Include <GuiEdit.au3>
_GUICtrlEditSetSel($h_edit, $i_start, $i_end)

Parameters

$h_edit	control id/control hWnd
$i_start	Specifies the starting character position of the selection.
$i_end	Specifies the ending character position of the selection.

Return Value

None.

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 $i_start is 0 and the $i_end is û1, all the text in the edit control is selected.
If the $i_start is û1, any current selection is deselected.

The control displays a flashing caret at the $i_end position regardless of the relative values of $i_start and $i_end.
