ITypeInfo2 Interface

IID_ITypeInfo2

{00020412-0000-0000-C000-000000000046

An ITypeInfo2 can be cast to an ITypeInfo instead of using the calls QueryInterface() and Release() to allow quick opens and allocs. This only works for in-process cases.

Methods in VTable order

IUnknown Methods

Description

QueryInterface

Returns pointers to supported interfaces.

AddRef

Increments reference count.

Release

Decrements reference count.

ITypeInfo Methods

Description

GetTypeAttr

Retrieves a TYPEATTR structure that contains the attributes of the type description.

GetTypeComp

Retrieves the ITypeComp interface for the type description, which enables a client compiler to bind to the type description's members.

GetFuncDesc

Retrieves the FUNCDESC structure that contains information about a specified function.

GetVarDesc

Retrieves a VARDESC structure that describes the specified variable.

GetNames

Retrieves the variable with the specified member ID (or the name of the property or method and its parameters) that correspond to the specified function ID.

GetRefTypeOfImplType

If a type description describes a COM class, it retrieves the type description of the implemented interface types. For an interface, GetRefTypeOfImplType returns the type information for inherited interfaces, if any exist.

GetImplTypeFlags

Retrieves the IMPLTYPEFLAGS enumeration for one implemented interface or base interface in a type description.

GetIDsOfNames

Maps between member names and member IDs, and parameter names and parameter IDs.

Invoke

Invokes a method, or accesses a property of an object, that implements the interface described by the type description.

GetDocumentation

Retrieves the documentation string, the complete Help file name and path, and the context ID for the Help topic for a specified type description.

GetDllEntry

Retrieves a description or specification of an entry point for a function in a DLL.

GetRefTypeInfo

If a type description references other type descriptions, it retrieves the referenced type descriptions.

AddressOfMember

Retrieves the addresses of static functions or variables, such as those defined in a DLL.

CreateInstance

Creates a new instance of a type that describes a component object class (coclass).

GetMops

Retrieves marshaling information.

GetContainingTypeLib

Retrieves the containing type library and the index of the type description within that type library.

ReleaseTypeAttr

Releases a TYPEATTR previously returned by GetTypeAttr.

ReleaseFuncDesc

Releases a FUNCDESC previously returned by GetFuncDesc.

ReleaseVarDesc

Releases a VARDESC previously returned by GetVarDesc.

ITypeInfo2 Methods

Description

GetTypeKind

Returns the TYPEKIND enumeration quickly, without doing any allocations.

GetTypeFlags

Returns the type flags without any allocations. This returns a DWORD type flag, which expands the type flags without growing the TYPEATTR (type attribute).

GetFuncIndexOfMemId

Binds to a specific member based on a known DISPID, where the member name is not known (for example, when binding to a default member).

GetVarIndexOfMemId

Binds to a specific member based on a known DISPID, where the member name is not known (for example, when binding to a default member).

GetCustData

Gets the custom data.

GetFuncCustData

Gets the custom data from the specified function.

GetParamCustData

Gets the specified custom data parameter.

GetVarCustData

Gets the variable for the custom data.

GetImplTypeCustData

Gets the implementation type of the custom data.

GetDocumentation2

Retrieves the documentation string, the complete Help file name and path, the localization context to use, and the context ID for the library Help topic in the Help file.

GetAllCustData

Gets all custom data items for the library.

GetAllFuncCustData

Gets all custom data from the specified function.

GetAllParamCustData

Gets all of the custom data for the specified function parameter.

GetAllVarCustData

Gets the variable for the custom data.

GetAllImplTypeCustData

Gets all custom data for the specified implementation type.
