OLE/COM APIs

Provides the Component Object Model (COM), as well as Object Linking and Embedding (OLE).

Functions

CLSIDFromProgID(Pointer<Utf16> lpszProgID, Pointer<GUID> lpclsid) → int

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

CLSIDFromProgIDEx(Pointer<Utf16> lpszProgID, Pointer<GUID> lpclsid) → int

Triggers automatic installation if the COMClassStore policy is enabled.

CLSIDFromString(Pointer<Utf16> lpsz, Pointer<GUID> pclsid) → int

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

CoAddRefServerProcess() → int

Increments a global per-process reference count.

CoCreateGuid(Pointer<GUID> pguid) → int

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

CoCreateInstance(Pointer<GUID> rclsid, Pointer<COMObject> pUnkOuter, int dwClsContext, Pointer<GUID> riid, Pointer<Pointer<NativeType>> ppv) → int

Creates a single uninitialized object of the class associated with a specified CLSID. Call CoCreateInstance when you want to create only one object on the local system. To create a single object on a remote system, call the CoCreateInstanceEx function. To create multiple objects based on a single CLSID, call the CoGetClassObject function.

CoGetClassObject(Pointer<GUID> rclsid, int dwClsContext, Pointer<NativeType> pvReserved, Pointer<GUID> riid, Pointer<Pointer<NativeType>> ppv) → int

Provides a pointer to an interface on a class object associated with a specified CLSID. CoGetClassObject locates, and if necessary, dynamically loads the executable code required to do this.

CoGetCurrentProcess() → int

Returns a value that is unique to the current thread. CoGetCurrentProcess can be used to avoid thread ID reuse problems.

CoInitializeEx(Pointer<NativeType> pvReserved, int dwCoInit) → int

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.

CoInitializeSecurity(Pointer<NativeType> pSecDesc, int cAuthSvc, Pointer<SOLE_AUTHENTICATION_SERVICE> asAuthSvc, Pointer<NativeType> pReserved1, int dwAuthnLevel, int dwImpLevel, Pointer<NativeType> pAuthList, int dwCapabilities, Pointer<NativeType> pReserved3) → int

Registers security and sets the default security values for the process.

CoSetProxyBlanket(Pointer<COMObject> pProxy, int dwAuthnSvc, int dwAuthzSvc, Pointer<Utf16> pServerPrincName, int dwAuthnLevel, int dwImpLevel, Pointer<NativeType> pAuthInfo, int dwCapabilities) → int

Sets the authentication information that will be used to make calls on the specified proxy. This is a helper function for IClientSecurity::SetBlanket.

CoTaskMemAlloc(int cb) → Pointer<NativeType>

Allocates a block of task memory in the same way that IMalloc::Alloc does.

CoTaskMemFree(Pointer<NativeType> pv) → void

Frees a block of task memory previously allocated through a call to the CoTaskMemAlloc or CoTaskMemRealloc function.

CoTaskMemRealloc(Pointer<NativeType> pv, int cb) → Pointer<NativeType>

Changes the size of a previously allocated block of task memory.

CoUninitialize() → void

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.

CoWaitForMultipleHandles(int dwFlags, int dwTimeout, int cHandles, Pointer<IntPtr> pHandles, Pointer<Uint32> lpdwindex) → int

Waits for specified handles to be signaled or for a specified timeout period to elapse.

CoWaitForMultipleObjects(int dwFlags, int dwTimeout, int cHandles, Pointer<IntPtr> pHandles, Pointer<Uint32> lpdwindex) → int

A replacement for CoWaitForMultipleHandles. This replacement API hides the options for CoWaitForMultipleHandles that are not supported in ASTA.

CreateStreamOnHGlobal(int hGlobal, int fDeleteOnRelease, Pointer<Pointer<COMObject>> ppstm) → int

The CreateStreamOnHGlobal function creates a stream object that uses an HGLOBAL memory handle to store the stream contents. This object is the OLE-provided implementation of the IStream interface.

GetHGlobalFromStream(Pointer<COMObject> pstm, Pointer<IntPtr> phglobal) → int

The GetHGlobalFromStream function retrieves the global memory handle to a stream that was created through a call to the CreateStreamOnHGlobal function.

IIDFromString(Pointer<Utf16> lpsz, Pointer<GUID> lpiid) → int

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

OleInitialize(Pointer<NativeType> pvReserved) → int

Initializes the COM library on the current apartment, and identifies the concurrency model as single-thread apartment (STA). Applications must initialize the COM library before they can call COM library functions other than CoGetMalloc and memory allocation functions.

OleUninitialize() → void

Closes the COM library on the apartment, releases any class factories, other COM objects, or servers held by the apartment, disables RPC on the apartment, and frees any resources the apartment maintains.

ProgIDFromCLSID(Pointer<GUID> clsid, Pointer<Pointer<Utf16>> lplpszProgID) → int

Retrieves the ProgID for a given CLSID.

StringFromCLSID(Pointer<GUID> rclsid, Pointer<Pointer<Utf16>> lplpsz) → int

Converts a CLSID into a string of printable characters. Different CLSIDs always convert to different strings.

StringFromGUID2(Pointer<GUID> rguid, Pointer<Utf16> lpsz, int cchMax) → int

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

StringFromIID(Pointer<GUID> rclsid, Pointer<Pointer<Utf16>> lplpsz) → int

Converts an interface identifier into a string of printable characters.
