Module Name:
|
||
|
|
|
||
|
|
RumbaOffice.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Ingnore the first call to NdrProxySendReceive if the ProcNum is 0x8013.
|
||
|
|
This prevents the RPC call from raising an exception because it's being
|
||
|
|
called from an ASYNC callback. The error it would normally return would be
|
||
|
|
RPC_E_CANTCALLOUT_INASYNCCALL. If it raises an exception, the app dies.
|
||
|
|
|
||
|
|
No idea why this works on 9X.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
