CoAllowSetForegroundWindow |
|
The system restricts
which processes can call the SetForegroundWindow function and
AllowSetForegroundWindow to set the foreground window. As a result, an
application is blocked from stealing the focus from another application even
when the user is interacting with it. The CoAllowSetForegroundWindow
function enables the COM server process called to take focus away from the
client application by using the IForegroundTransfer interface. The
COM client then yields the foreground window to the specified COM server
process whose proxy is pUnk. Yielding the foreground window is useful
when the client wants a window owned by the server process to take focus. |

CoFreeAllLibraries |
|

CoGetClassObject |
|
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.
Call CoGetClassObject directly when you want to create multiple objects through a class object for which there is a CLSID in the system registry. You can also retrieve a class object from a specific remote machine. Most class objects implement the IClassFactory interface. You would then call IClassFactory::CreateInstance to create an uninitialized object. It is not always necessary to go through this process. To create a single object, call instead the either the CoCreateInstanceEx function, which allows you to create an instance on a remote machine. This replaces the CoCreateInstance function, which can still be used to create an instance on a local machine. Both functions encapsulate connecting to the class object, creating the instance, and releasing the class object. Two other functions, CoGetInstanceFromFile and CoGetInstanceFromIStorage, provide both instance creation on a remote system, and object activation. OLE also provides many other ways to create an object in the form of numerous helper functions and interface methods whose function is to create objects of a single type and provide a pointer to an interface on that object.
Note
The CoGetClassObject function does not call CoLoadLibrary. |

Registers security
and sets the default security values for the process. This function is
called exactly once per process, either explicitly or implicitly. It can be
called by the client, server, or both. For legacy applications and other
applications that do not explicitly call CoInitializeSecurity, COM

Writes into a stream
the data required to initialize a proxy object in some client process. The
