ODBC, MAPI, Video for Windows, NetDDE, & RAS/RPC Under Win32s
ID: Q147432
|
The information in this article applies to:
-
Microsoft Win32s versions 1.30, 1.30a, 1.30c
The following interfaces are not completely supported under Win32s. Any
exceptions are noted.
- RAS API and RPC.
- Video for Windows API (note that the MCI interface is supported).
- MAPI interface (Also, a Win32s client can not thunk down to 16-bit MAPI
in Windows 3.x. You will have to write a 16-bit client that calls the
16-bit MAPI APIs, and then have the Win32s client thunk to this 16-bit
client). For more information on why a Win32s client (a 32-bit thunk
DLL) cannot thunk to the 16-bit MAPI DLL, please refer to the following
Knowledge Base article:
Q149710 Why Thunking to 16-bit MAPI Will Fail Under Win32s
- NetDDE interface.
- ODBC (Win32s supports only ODBC version 2.0 and 2.1. Later versions of
ODBC were not completely tested on Win32s).
