RegisterTypeLib function

Adds information about a type library to the system registry.

Syntax


HRESULT RegisterTypeLib(
  ITypeLib *ptlib,
  _In_      LPCOLESTR szFullPath,
  _In_opt_  LPCOLESTR szHelpDir
);

Parameters

ptlib

The type library.

szFullPath [in]

The fully qualified path specification for the type library.

szHelpDir [in, optional]

The directory in which the Help file for the library being registered can be found. This parameter can be null.

Return codeDescription
S_OK

Success.

E_INVALIDARG

One or more of the arguments is not valid.

E_OUTOFMEMORY

Insufficient memory to complete the operation.

The function could not write to the file.

TYPE_E_REGISTRYACCESS

The system registration database could not be opened.

TYPE_E_INVALIDSTATE

Remarks

This function can be used during application initialization to register the application's type library correctly. When RegisterTypeLib is called to register a type library, both the minor and major version numbers are registered in hexadecimal.

In addition to filling in a complete registry entry under the type library key, RegisterTypeLib adds entries for each of the dispinterfaces and Automation-compatible interfaces, including dual interfaces. This information is required to create instances of these interfaces. Coclasses are not registered (that is, RegisterTypeLib does not write any values to the CLSID key of the coclass).
