IXpsSignatureCollection::RemoveAt method (xpsdigitalsignature.h)

Article
02/22/2024

Removes and releases an IXpsSignature interface pointer from a specified location in the collection.

Syntax

HRESULT RemoveAt(
  UINT32 index
);

Parameters

index

The zero-based index in the collection from which an IXpsSignature interface pointer is to be removed and released.

Return value

If the method succeeds, it returns S_OK; otherwise, it returns an HRESULT error code.

Remarks

This method releases an interface referenced by the pointer at the location specified by index. After releasing the interface, this method compacts the collection by reducing by 1 the index of each pointer subsequent to index.

Once an interface has been removed from a collection, it is no longer valid. If an application retains a pointer to the interface that was removed and tries to call one of its methods, the method will return E_UNEXPECTED.
