Retrieves the number of lines
#include <GuiEdit.au3>
_GUICtrlEdit_GetLineCount ( $hWnd )
| $hWnd | Control ID/Handle to the control |
| Success: | the total number of text lines. |
| Failure: | 1. |
If the control has no text, the return value is 1.
The return value will never be less than 1.
The _GUICtrlEdit_GetLineCount() 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.
