Determines whether an object is currently in the running state.
BOOL IsRunning();
Return Values
TRUE
The object is in the running state.
FALSE
The object is not in the running state.
Comments
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.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
