PROP_ENTRY_INTERFACE

Lets you enter a property description, a property DISPID, and a list of property page CLSIDs into the property map for the object.

PROP_ENTRY_INTERFACE(
   szDesc,
   dispid,
   clsid,
   rgclsidAllowed,
   cclsidAllowed,
   vt
)

[in] szDesc

The property description.

[in] dispid

The DISPID of the property.

[in] clsid

The CLSID of the associated property page. Use the special value CLSID_NULL for a property that does not have an associated property page.

[in] rgclsidAllowed

An array of CLSIDs that can be loaded. For stability, use a const array.

[in] cclsidAllowed

The number of elements in rgclsidAllowed.

[in] vt

The type for the property.

Include this macro to give an application more control over the IPersistStreamInitImpl::Load process. This macro only applies if IPersistStreamInitImpl is a base class and the class is advertised as safe for initializing. Otherwise, you should not use this macro.

In most cases, cclsidAllowed can be determined by _countof(rgclsidAllowed).

This macro is only valid if vt is VT_DISPATCH or VT_UNKNOWN. Passing in a different value for vt to this macro will result in a compilation error. For any other value of vt, use PROP_ENTRY_TYPE.

The BEGIN_PROP_MAP macro marks the beginning of the property map; the END_PROP_MAP macro marks the end.

If you are creating a web control that needs to be initialized, you should use the IPersistPropertyBagImpl Class instead of IPersistStreamInitImpl to initialize properties. IPersistStreamInitImpl possess a greater risk in binary format than IPersistPropertyBagImpl.
