    The object you are using hasn't been initialize with a NEW statement.  You probably have a typo error in you program.  A window object like a control has a handle number which is the window number or process number.  An variable that hasn't been set to a value is pointing to NULL so it won't have a handle number.  I suspect you have a NULL object which is giving the error message.
