WTS API Call

[netman]

To my knowledge, the API routines for Windows Terminal Server are not documented on allapi.net. I can call some of them from VB, but I can' get WTSQuerySessionInformation to work. I think it might have something to do with the enum field you have to pass it, WTS_INFO_CLASS. Maybe VB doesn't pass enum fields to C. Has anybody called this routine successfully?

Thanks,

Ken

Enums in start counting from zero, they are passed ByVal as Integer. Start with the first one - it's zero, the next one in the enum is 1, next 2, etc.

Here is the enum:

typedef enum _WTS_INFO_CLASS {
  WTSInitialProgram,             0
  WTSApplicationName,         1
  WTSWorkingDirectory,        2  ,etc.
  WTSOEMId,
  WTSSessionId,
  WTSUserName,
  WTSWinStationName,
  WTSDomainName,
  WTSConnectState,
  WTSClientBuildNumber,
  WTSClientName,
  WTSClientDirectory,
  WTSClientProductId,
  WTSClientHardwareId,
  WTSClientAddress,
  WTSClientDisplay,
  WTSClientProtocolType
} 
WTS_INFO_CLASS;

Pick one of the values, eg.:

Const WTSWorkingDirectory = 2

and pass it as a constant ByVal.

Must be something else wrong. Still get a "false" on the return status from the call, but GetLastError returns a 0. I found a chunk of sample code on a microsoft.public newsgroup which I'm going to try.
