IXpsOMDictionary::InsertAt method
Inserts an IXpsOMShareable interface at a specified location in the dictionary and sets the key to identify the interface.
Syntax
HRESULT InsertAt(
[in] UINT32 index,
[in] LPCWSTR key,
[in] IXpsOMShareable *entry
);
Parameters
index [in]
The zero-based index in the dictionary where the IXpsOMShareable interface is to be inserted.key [in]
The key to be used to identify the IXpsOMShareable interface in the dictionary.The string referenced by key must be unique in the dictionary.
entry [in]
The IXpsOMShareable interface pointer to be inserted at the location specified by index.A dictionary cannot contain duplicate interface pointers. This parameter must contain an interface pointer that is not already in the dictionary.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.
| Return code | Description |
|---|---|
| S_OK | The method succeeded. |
| XPS_E_NO_CUSTOM_OBJECTS | entry does not point to a recognized interface implementation. Custom implementation of XPS Document API interfaces is not supported. |
Remarks
The interface pointers stored in the dictionary will usually be pointers to interfaces, such as IXpsOMBrush and IXpsOMVisual, that are derived from the IXpsOMShareable interface. To determine the interface type, call the IXpsOMShareable::GetType method.
At the location specified by index, this method inserts the IXpsOMShareable interface pointer and sets the key; the interface pointer and key are passed in value and key, respectively. Before value and key are inserted, the interface pointer and the key at this and all subsequent locations are moved up by one index.
