Function Reference

_GUICtrlEditGetLineCount

Retrieves the number of lines in a multiline edit control.

#Include <GuiEdit.au3>
_GUICtrlEditGetLineCount($h_edit)

Parameters

$h_edit

control id/control hWnd

Return Value

The return value is an integer specifying the total number of text lines in the multiline edit control.

Remarks

If the control has no text, the return value is 1.
The return value will never be less than 1.

The _GUICtrlEditGetLineCount retrieves the total number of text lines,
not just the number of lines that are currently visible.

If the Wordwrap feature is enabled, the number of lines can change when the dimensions of the editing window change.

Example

#include <GUIConstants.au3>
#include <GuiEdit.au3>

opt('MustDeclareVars', 1)

Dim $myedit, $Status, $msg

GUICreate("Edit Get Line Count", 392, 254)
