In my OCX, I want to define a property which will not appear at design time, in the property sheet, but will be available at run time.

This is an Error property which will hold a value. This has no use at design time. So, this is why I don't want it to appear in the property sheet.

At this point, I have about 20 properties which appear in the property sheet at design time.

What difference should I do to not have the Error property appear in the property sheet?
