CoCreateGuid

WinNT.HRESULT CoCreateGuid(Guid.GUID pguid)

Creates a GUID, a unique 128-bit integer used for CLSIDs and interface identifiers.

Parameters:

pguid - A pointer to the requested GUID.

Returns:

S_OK if the GUID was successfully created.

CoCreateGuid

WinNT.HRESULT CoCreateGuid(Guid.GUID.ByReference pguid)

Deprecated. use CoCreateGuid(Guid.GUID).

StringFromGUID2

int StringFromGUID2(Guid.GUID rguid,
                    char[] lpsz,
                    int cchMax)

Converts a globally unique identifier (GUID) into a string of printable characters.

Parameters:

rguid - The GUID to be converted.

lpsz - A pointer to a caller-allocated string variable to receive the resulting string.

cchMax - The number of characters available in the lpsz buffer.

Returns:

If the function succeeds, the return value is the number of characters in the returned string, including the null terminator. If the buffer is too small to contain the string, the return value is 0.

IIDFromString

WinNT.HRESULT IIDFromString(String lpsz,
                            Guid.GUID lpiid)

Converts a string generated by the StringFromIID function back into the original interface identifier (IID).

Parameters:

lpsz - A pointer to the string representation of the IID.

lpiid - A pointer to the requested IID on return.

Returns:

This function can return the standard return values E_INVALIDARG, E_OUTOFMEMORY, and S_OK.

CoInitialize

WinNT.HRESULT CoInitialize(WinDef.LPVOID pvReserved)

Initializes the COM library on the current thread and identifies the concurrency model as single-thread apartment (STA). New applications should call CoInitializeEx instead of CoInitialize. pvReserved [in, optional] This parameter is reserved and must be NULL.

Parameters:

pvReserved - the pv reserved

Returns:

S_OK The COM library was initialized successfully on this thread. S_FALSE The COM library is already initialized on this thread. RPC_E_CHANGED_MODE A previous call to CoInitializeEx specified the concurrency model for this thread as multithread apartment (MTA). This could also indicate that a change from neutral-threaded apartment to single-threaded apartment has occurred.

CoInitializeEx

WinNT.HRESULT CoInitializeEx(Pointer reserved,
                             int dwCoInit)

Initializes the COM library for use by the calling thread, sets the thread's concurrency model, and creates a new apartment for the thread if one is required.

Parameters:

reserved - This parameter is reserved and must be NULL.

dwCoInit - The concurrency model and initialization options for the thread. Values for this parameter are taken from the COINIT enumeration. Any combination of values from COINIT can be used, except that the COINIT_APARTMENTTHREADED and COINIT_MULTITHREADED flags cannot both be set. The default (and only sane choice) is COINIT_MULTITHREADED.

Returns:

This function can return the standard return values E_INVALIDARG, E_OUTOFMEMORY, and E_UNEXPECTED, as well as the following values. S_OK, S_FALSE, RPC_E_CHANGED_MODE

CoUninitialize

void CoUninitialize()

Closes the COM library on the current thread, unloads all DLLs loaded by the thread, frees any other resources that the thread maintains, and forces all RPC connections on the thread to close.

CoCreateInstance

WinNT.HRESULT CoCreateInstance(Guid.GUID rclsid,
                               Pointer pUnkOuter,
                               int dwClsContext,
                               Guid.GUID riid,
                               PointerByReference ppv)

Creates a single uninitialized object of the class associated with a specified CLSID.

Parameters:

rclsid - The CLSID associated with the data and code that will be used to create the object.

pUnkOuter - If NULL, indicates that the object is not being created as part of an aggregate. If non-NULL, pointer to the aggregate object's IUnknown interface (the controlling IUnknown).

dwClsContext - Context in which the code that manages the newly created object will run. The values are taken from the enumeration CLSCTX defined in WTypes.

riid - A reference to the identifier of the interface to be used to communicate with the object.

ppv - Address of pointer variable that receives the interface pointer requested in riid. Upon successful return, *ppv contains the requested interface pointer. Upon failure, *ppv contains NULL.

Returns:

an HRESULT

CLSIDFromProgID

WinNT.HRESULT CLSIDFromProgID(String lpszProgID,
                              Guid.CLSID lpclsid)

Looks up a CLSID in the registry, given a ProgID.

Parameters:

lpszProgID - [in] A pointer to the ProgID whose CLSID is requested.

lpclsid - [out] Receives a pointer to the retrieved CLSID on return.

Returns:

S_OK The CLSID was retrieved successfully. CO_E_CLASSSTRING The registered CLSID for the ProgID is invalid. REGDB_E_WRITEREGDB 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.

CLSIDFromString

WinNT.HRESULT CLSIDFromString(WString lpsz,
                              Guid.CLSID pclsid)

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

Parameters:

lpsz - [in] The string representation of the CLSID.

pclsid - [out] A pointer to the CLSID.

Returns:

Return value This function can return the standard return value E_INVALIDARG, as well as the following values. NOERROR The CLSID was obtained successfully. CO_E_CLASSSTRING The class string was improperly formatted. REGDB_E_CLASSNOTREG The CLSID corresponding to the class string was not found in the registry. REGDB_E_READREGDB The registry could not be opened for reading.
