/***************************************************************************

|
|
** File: odbcexec.h
|
||
|
|
** Purpose: Contains defines used by both the 16 and 32 bit ends
|
||
|
|
** of the ODBC communication channel.
|
||
|
|
**
|
||
|
|
** Notes: This header files contains code, so it cannot be
|
||
|
|
** included in more than one compilation unit. The
|
||
|
|
** reason it contains code is that GetTransferFileName()
|
||
|
|
** is used on both the 16 and 32 bit sides, and this is
|
||
|
|
** simpler than creating a shared .cpp file just for it.
|
||
