Return value
This function can return the following values.

|---|---|
|
The CLSID was retrieved successfully. |
|
The registered CLSID for the ProgID is invalid. |

An error occurred writing the CLSID to the registry. See Remarks below. |
Remarks
Given a ProgID, CLSIDFromProgID looks up its associated CLSID in the registry. If the ProgID cannot be found in the registry, CLSIDFromProgID creates an OLE 1 CLSID for the ProgID and a CLSID entry in the registry. Because of the restrictions placed on OLE 1 CLSID values, CLSIDFromProgID and CLSIDFromString are the only two functions that can be used to generate a CLSID for an OLE 1 object.
