SYMPTOMS
OLE type emulation is the process that allows the application user to specify that all objects of some particular type are henceforth to be activated as objects of some alternate, emulating type. When objects of the original type are subsequently run, the server for the emulating type is launched to serve them.

However, this emulation does not occur for objects of the original type that were already in the loaded state when the type emulation occurred. When such objects are subsequently run, they are run as the original type, not the emulating type. The original server is launched, not the server for the emulating type.

<div class="cause_section">

CAUSE
When an object is in the loaded state, its object handler is running. The handler is, in general, particular to the original type for that object, and therefore cannot emulate another object type.

<div class="status_section">

STATUS
Microsoft has confirmed this to be a problem with the Microsoft products listed at the beginning of this article.

<div class="moreinformation_section">

MORE INFORMATION
If a container application has previously loaded instances of the original type, it should reload each such object as the alternative, emulating type the next time that object is run.

For more information on OLE type emulation, see "Emulating Different Object Types" in the Object Linking and Embedding Software Development Kit (SDK) version 2.01 "Programmer's Reference" help file.
