ProxyGen Descriptor Schema Reference

Article
11/16/2012

The Proxy Generation tool (ProxyGen.exe) uses the ProxyGen descriptor schema to generate XML proxy descriptor files. Proxy descriptor files contain an XML representation of the types in the COM type library or managed assembly that contains your application's object model. If you modify the object model by editing the proxy descriptor file, your changes must validate according to the ProxyGen descriptor schema. For more information, see Defining Entry Points and Other Proxy Changes.

The ProxyGen descriptor schema is named ProxyGenDescriptorV2.xsd, and is installed by default to the following folder on your development computer: %ProgramFiles%\Visual Studio Tools for Applications 2.0 SDK\build number\Visual Studio Tools For Applications\Schemas.

The root element is the Library element. The following table describes all of the elements defined by the ProxyGen descriptor schema.

Element	Description
Attribute	Represents an attribute of a type, member, or parameter.
BaseType	Represents a base type that another type derives from.
Class Element for COMLibrary	Represents a proxy class for a COM class in the host application's object model.
Class Element for ManagedLibrary	Represents a proxy class for a managed class in the host application's object model.
COMLibrary	Represents the contents of a COM type library that contains the host application's object model.
Constant	Represents a constant that is defined in a proxy type for a COM or managed type.
DeclaringType	Represents the interface or base type in which a member is declared, if the member is an explicit interface implementation or an override.
DefaultNullValue	Indicates that a parameter has a null default value.
DefaultValue	Specifies the default value of a parameter.
Delegate	Represents a proxy delegate for a managed delegate that is defined in a parent class, or represents a proxy delegate that handles a COM event.
Delegate Element for ManagedLibrary	Represents a proxy delegate for a managed delegate that is not defined in a parent class.
Enum	Represents a proxy enumeration for a COM or managed enumeration.
EnumerationValue	Represents a member of a proxy enumeration for a COM or managed enumeration.
Event Element for Class for COMLibrary	Represents an event that is defined in a proxy type for a COM type.
Event Element for Class for ManagedLibrary	Represents an event that is defined in a proxy type for a managed type.
Exception	Represents a proxy exception for a managed exception.
ExternalTypeReference	Describes a type that is not defined in the proxy descriptor file. The type can be an array.
ExternalTypeReference Element for Type for Attribute or Event	Describes a type that is not defined in the proxy descriptor file. The type cannot be an array.
ExternalTypeReference Element for UnderlyingType	Describes the underlying integral type of an enumeration.
Field	Represents a field that is defined in a proxy exception for a managed exception.
Get	Represents the get accessor of a property of a COM or managed type.
ImplementedInterface	Represents an interface that another type implements.
Interface Element for COMLibrary	Represents a proxy interface for a COM interface in the host application's object model.
Interface Element for ManagedLibrary	Represents a proxy interface for a managed interface in the host application's object model.
Library	Required root element of a proxy descriptor file generated by using ProxyGen.exe. The proxy descriptor file describes the contents of either a COM type library or a managed assembly.
ManagedLibrary	Represents the contents of a managed assembly that contains the host application's object model.
Method Element for Class for COMLibrary	Represents a method that is defined in a proxy type for a COM type.
Method Element for Class for ManagedLibrary	Represents a method that is defined in a proxy type for a managed type.
NamedNullParameter	Represents a named parameter of an attribute's constructor that is passed the value null.
NamedParamter	Represents a named parameter of an attribute's constructor.
NullParameter	Represents a positional parameter of an attribute's constructor that is passed the value null.
NullValue	Indicates that a constant has a null value.
Parameter	Represents a parameter of a member or delegate type.
Parameter Element for Attribute	Represents a positional parameter of an attribute's constructor.
Property Element for Class for COMLibrary	Represents a property that is defined in a proxy type for a COM type.
Property Element for Class for ManagedLibrary	Represents a property that is defined in a proxy type for a managed type.
ReturnType	Represents the type of the return value of a method.
ReturnValueAttribute	Represents an attribute that is applied to the return value of a member or delegate type.
Set	Represents the set accessor of a property of a COM or managed type.
Struct Element	Represents a proxy class for a managed struct in the host application's object model.
Type	Represents a reference to a type that is used in the declaration of a member or parameter.
Type Element for Attribute or Event	Represents a reference to a type that is used in the declaration of an attribute or event.
TypeReference	Describes a type that is defined in the proxy descriptor file. The type can be an array.
TypeReference Element for Type for Attribute or Event	Describes a type that is defined in the proxy descriptor file. The type cannot be an array.
UnderlyingType	Represents the underlying integral type of a proxy enumeration for a COM or managed enumeration.
Value	Specifies the value of a constant.
