SAMPLE: VTBLBIND: Marshaling Using an OLE Automation Marshaler

 Last reviewed: June 6, 1996
Article ID: Q139074
The information in this article applies to:
  • Microsoft OLE libraries included with: 

        - Microsoft Windows NT version 3.51
    - Microsoft Windows 95

SUMMARY

The VTBLBIND sample demonstates how to use the OLE Automation marshaler to marshal a custom interface.

Download VTBLBIND.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

  • The Microsoft Network 

          On the Edit menu, click Go To, and then click Other Location
      Type mssupport
      Double-click the MS Software Library icon
      Find the appropriate product area
      Download VTBLBIND.EXE (size: 37250 bytes)
  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download VTBLBIND.EXE (size: 37250 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the Softlib\Mslfiles directory
      Get VTBLBIND.EXE (size: 37250 bytes)

After downloading the file, use the following command to extract its contents and create the apprpriate directory structure: 

   VTBLBIND.EXE -d

MORE INFORMATION

Standard marshaling code for custom COM interfaces, generated using the MIDL compiler or written manually, doesn't support 16/16 bit and 16/32 bit interoperability in Windows 95 and Windows NT 3.51. The OLE Automation marshaler, however, does support 16/16 bit and 16/32 bit interoperability for local servers (.exe servers), so you can use it to work around this interoperability problem if you are interested in 16-bit support. However, the types that can be used in interfaces that can be marshaled by the OLE Automation marshaler are restricted to the OLE Automation compatible types.
