CLSIDFromString

Converts a string generated by the StringFromCLSID function back into the original CLSID.

HRESULT CLSIDFromString(
LPOLESTR lpsz, //Pointer to the string representation of the CLSID
LPCLSID pclsid //Pointer to the CLSID
);
 

Parameters

lpsz

[in] Pointer to the string representation of the CLSID.
 

pclsid

[out] Pointer to the CLSID on return.
 

Return Values

This function supports the standard return value E_INVALIDARG, as well as the following:
 

NOERROR

The CLSID was obtained successfully.
 

CO_E_CLASSTRING

The class string was improperly formatted.
 

REGDB_E_WRITEREGDB

The CLSID corresponding to the class string was not found in the registry.
 

Remarks

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.
