Editor: This type library is used in many of the samples of this site and contains a lot of interface declarations that are not exposed to VB by Windows. The .zip archive also includes the library "OLELIB2.TLB" which has some of the interfaces that are included in "OLELIB.TLB" but declared to be used with the Implements keyword. Some samples are also included. After you unzip the File Copy the both type libraries to the Windows/System32 folder and register them with regtlib.exe.
