Remarks
Call this method to restore the in-place edit field's text to that prior to the last cut, paste, or delete operation.
Microsoft appears to have built a minor error into the List-View, in-place, edit control's undo ("EM_UNDO") functionality, in that EM_UNDO only restores the last three (3) letters of a modified caption, after cut and/or delete operations, and not the entire text that was removed (i.e. the text that was highlighted prior to the operation). However, if editing is subseqhently terminated by selecting another item or pressing the escape key, the entire caption text will be restored. It should also be stressed that this bug appears to be restricted to the in-place edit fields in List- and Tree-View controls.
The method is only effective while the read-only EditHandle property returns a valid handle to the in-place edit control/field.
The method cannot be applied to subitems.
