SUMMARY

BINARY is an OLE Automation server that you can obtain from the Microsoft Download Center. 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.

Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file. 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 transfer 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.
