>>Is there a way to assign property values to a group of objects if there is not a value already asssigned? I'm looking to set all the HelpContextID properties for objects on a page (form, pageframe, whatever...) to a specific value unless they have previously been assigned in development. I'm trying to think of a way to use the SetAll method to handle this... Thanks!

Hi David,

Your example first sets ProtectHelpContextID to .t., then according to the method you wrote, it would not assign 999 to HelpContextID.

Actually, this is exactly what I meant, when wrote a message to Renoir. We probably don't need the property ProtectHelpContextID, though it may be a good idea to have it.
