  Thanx for responding!

  I tried the code snipet below, and I get a lot of errors. After a little
experimentation, I've narrowed it down to not liking the inclusion of
"windows.h". It needs it to recognize PlaySound() and SND_FILENAME, but a
subset of the errors it gives with windows.h are as follows:

  C:\Program Files\Microsoft Visual Studio
.NET\Vc7\PlatformSDK\Include\ObjIdl.h(7385): error C2371: 'IDataObject' :
redefinition; different basic types

  C:\Program Files\Microsoft Visual Studio
.NET\Vc7\PlatformSDK\Include\ObjIdl.h(7894): error C2371: 'IMessageFilter' :
redefinition; different basic types

  c:\Program Files\Microsoft Visual Studio
.NET\Vc7\PlatformSDK\Include\ServProv.h(92): error C2872: 'IServiceProvider'
: ambiguous symbol
     :
     :
   etc.

  and other errors that look like just these same errors being repeated many
times. I'm doing a MANAGED windows program, is that the problem?
