loadtypelib (oleaut32)
 
.
Summary
The LoadTypeLib function loads a type library from a file. It optionally registers a type library when no file is specified. (see Notes)

C# Signature:

[DllImport("oleaut32.dll", CharSet=CharSet.Unicode, ExactSpelling=true )]
static extern int LoadTypeLib(string fileName, out ITypeLib typeLib);

VB.Net Signatures:

Declare Unicode Function LoadTypeLib Lib "oleaut32.dll" (ByVal szFile As String, ByRef TPpTypeLib As System.Runtime.InteropServices.ComTypes.ITypeLib) As Integer

VB 6 Signature:

Declare Function LoadTypeLib Lib "oleaut32.dll" (szFile As Byte, pTLB As Object) As Long

User-Defined Types:

None.

Alternative Managed API:

Do you know one? Please contribute it!

Notes:

In VB.Net you can substitute System.Runtime.InteropServices.ComTypes.ITypeLib2 or System.Runtime.InteropServices.UCOMITypeLib for System.Runtime.InteropServices.ComTypes.ITypeLib, defined in mscorlib.dll.

Note that in v2.0 (Whidbey) of the .NET Framework, the System.Runtime.InteropServices.UCOMITypeLib interface has been deprecated in favor of System.Runtime.InteropServices.ComTypes.ITypeLib.

For backward compatibility, LoadTypeLib will register the type library if the path is not specified in the szFile parameter. LoadTypeLib will not register the type library if the path of the type library is specified. It is recommended that RegisterTypeLib be used to register a type library.
