PRB: SQLGetData w/ SQL_C_BINARY Causes GPF in 16-bit ODBC Test

WORKAROUND

1. Specify cbValueMax large enough to get data back by one SQLGetData call.
2. Replace SQL_C_BINARY with SQL_C_CHAR for fCType. The following text is an excerpt from "ODBC 2.0 Programmer's Reference Book," Appendix D. Please refer to this book for more information before you use this method:

   When binary SQL data is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary 00000001 is converted to "01" and a binary 11111111 is converted to "FF".
   
   The driver always converts individual bytes to pairs of hexadecimal digits and terminates the character string with a null byte. Because of this, if cbValueMax is even and is less than the length of the converted data, the last byte of the rgbValue buffer is not used. (The converted data requires an even number of bytes, the next-to-last byte is a null byte, and the last byte cannot be used.)
