MIDL and COM

All COM objects implement one or more interfaces. When you create a custom COM object, you must describe the interface or interfaces in an IDL file. The topics in this section present information on using MIDL to define COM interfaces:

• Files Generated for a COM Interface
• Marshaling OLE Data Types

For more information on defining COM interfaces with MIDL, see Defining COM Interfaces. For more information on building generated files for various platforms, see Targeting Stubs for Specific 32-bit or 64-bit Platforms.
