FIX: Out of Order Definitions in idl May Cause Compiler Errors (172985)
The information in this article applies to:
- Microsoft Visual C++, 32-bit Enterprise Edition 5.0
- Microsoft Visual C++, 32-bit Professional Edition 5.0
This article was previously published under Q172985 SYMPTOMS
When using the #import directive, errors may be generated due to the order
in which definitions appear in the idl file used to generate the type
library. The sample below causes error C2504, base class undefined, due to
the interfaces being defined globally instead of in the library block.
RESOLUTION
Move the interface definitions into the library block.
Create an extraneous reference to the class that the compiler is generating
an error from within the library block.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This bug has been fixed in Visual Studio
97 Service Pack 3.
