> IsParentForm    

Occasionally, we may have a Form object that may be used either by itself or as a source for a subform. In such situations, attempting to refer to form's Parent property will result in a runtime error. This functions provides a simple test so code that are meant to be run whenever form is opened as subform and not when it's opened by itself without any errors.
