CLSID Key

A CLSID is a globally unique identifier that identifies an OLE class object. If your server or container allows linking to its embedded objects, then you need to register a CLSID for each supported class of objects.

Registry Entry

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID = <CLSID>

Value Entries

<CLSID>

Specifies a name that can be displayed in the user interface.

Remarks

The CLSID key contains information used by the default OLE handler to return information about a class when it is in the running state.

To obtain a CLSID for your application, you can use the UUIDGEN.EXE found in the \TOOLs directory of the OLE 2 Toolkit, or use CoCreateGuid.

The CLSID is a 128 bit number, spelled in hex, within a pair of brarces.
