IRunnableObject::IsRunning method (objidl.h)
Determines whether an object is currently in the running state.
Syntax
BOOL IsRunning();
Return value
If the object is in the running state, the return value is TRUE. Otherwise, it is FALSE.
Remarks
A container application could call IRunnableObject::IsRunning when it needs to know if the server is immediately available. For example, a container's implementation of the IOleItemContainer::GetObject method would return an error if the server is not running and the bindspeed parameter specifies BINDSPEED_IMMEDIATE.
An object handler could call IRunnableObject::IsRunning when it wants to avoid conflicts with a running server or when the running server might have more up-to-date information. For example, a handler's implementation of IOleObject::GetExtent would delegate to the object server if it is running, because the server's information might be more current than that in the handler's cache.
OleIsRunning is a helper function that conveniently repackages the functionality offered by IRunnableObject::IsRunning. With the release of OLE 2.01, the implementation of OleIsRunning was changed so that it calls QueryInterface, asks for IRunnableObject, and then calls IRunnableObject::IsRunning. In other words, you can use the interface and the helper function interchangeably.
