Issue when accessing the property/method of a Calender control
 

Hi,

I am using a calender control in my excel sheet and written the following
code,

Sheets("ABC").Calendar1.Visible = False

This was working for a long time and suddenly few days back the above
mentioned line started giving 'Property or method cannot be accessed' Run
time error 438. Can any one tell me the reason behind this error?

Thanks,

Regards,
Anand
