IFileOperation::ApplyPropertiesToItems method (shobjidl_core.h)

Declares a set of items for which to apply a common set of property values.

Syntax

HRESULT ApplyPropertiesToItems(
  [in] IUnknown *punkItems
);

Parameters

[in] punkItems

Type: IUnknown*

Pointer to the IUnknown of the IShellItemArray, IDataObject, or IEnumShellItems object which represents the group of items. You can also point to an IPersistIDList object to represent a single item, effectively accomplishing the same function as IFileOperation::ApplyPropertiesToItem.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

This method does not apply the properties to the items, it merely declares the items. To set property values on a group of items, you must make at least the sequence of calls detailed here:

1. Call IFileOperation::SetProperties to declare the specific properties to be set and their new values.
2. Call IFileOperation::ApplyPropertiesToItems to declare the items whose property values are to be set.
3. Call IFileOperation::PerformOperations to apply the properties to the items.
