IRunnableObject::IsRunning (Windows Embedded CE 6.0)

1/6/2010

This method determines whether an object is currently in the running state.

Syntax

BOOL IsRunning();

Parameters

None.

Return Value

  • TRUE
    The object is in the running state.
  • FALSE
    The object is not in the running state.

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.

To determine whether the platform supports this interface, see Determining Supported COM APIs.

Requirements

Header objidl.h, objidl.idl
Library ole32.lib, uuid.lib
Windows Embedded CE Windows CE 3.0 and later
