The ListView_EditLabel macro begins in-place editing of the specified list view itemís text. The message implicitly selects and focuses the specified item. You can use this macro or explicitly send the LVM_EDITLABEL message.
Returns the handle of the edit control that is used to edit the item text if successful or NULL otherwise.
When the user completes or cancels editing, the edit control is destroyed and the handle is no longer valid. You can safely subclass the edit control, but you should not destroy it.
The control must have the focus before you send this message to the control. Focus can be set using the SetFocus function.
