SAMPLE: BINARY: Transfer Binary Data Using OLE Automation

Last reviewed: August 5, 1996

The information in this article applies to:
  • Microsoft OLE Libraries for Windows and Win32s, version 2.03
  • Microsoft OLE libraries included with:

        - Microsoft Windows NT version 3.5
        - Microsoft Windows 95
    

BINARY is an OLE Automation server that you can obtain from the Microsoft Software Library. It demonstrates how to transfer binary data using a SAFEARRAY of unsigned char. The CTRL directory in this sample contains an automation controller that will obtain the binary data from the server.

Binary data can be transferred with OLE Automation by using a SAFEARRAY of unsigned char (VT_ARRAY|VT_UI1). Binary data can also be transferred by passing the IUnknown of a data trasfer object that supports IDataObject. This sample uses the first approach, not the second.

Standard controllers like Visual Basic may be able to pass binary data to an automation server using the approach discussed in Don Box's column in the June 1996 issue of the Microsoft Systems Journal.

See the README.TXT in the sample for details on how to compile and run the sample. After you download BINARY.EXE, use the following command to run it:

    BINARY.EXE -d

This builds the directory structure for you.
