I am trying to use the function WTSQuerySessionInformation
in a Visual C# project, including the following lines in the class definition:
[DllImport("Wtsapi32.dll")]
static extern bool WTSQuerySessionInformation(
System.IntPtr hServer, int sessionId, WTS_INFO_CLASS wtsInfoClass, out System.IntPtr ppBuffer, out uint pBytesReturned); private Boolean remote_connected = false;
I get an error saying:
Error: he type or namespace name 'WTS_INFO_CLASS' could not be found (are you missing a using directive or an assembly reference?)
Can anyone please let me know what needs to be done in the project to fix this error?
You are nearly there:
enum WTS_INFO_CLASS
{
WTSInitialProgram,
WTSApplicationName,
WTSWorkingDirectory,
WTSOEMId,
WTSSessionId,
WTSUserName,
WTSWinStationName,
WTSDomainName,
WTSConnectState,
WTSClientBuildNumber,
WTSClientName,
WTSClientDirectory,
WTSClientProductId,
WTSClientHardwareId,
WTSClientAddress,
WTSClientDisplay,
WTSClientProtocolType,
WTSIdleTime,
WTSLogonTime,
WTSIncomingBytes,
WTSOutgoingBytes,
WTSIncomingFrames,
WTSOutgoingFrames,
WTSClientInfo,
WTSSessionInfo
};
[DllImport("Wtsapi32.dll", SetLastError=true)]
static extern bool WTSQuerySessionInformation(
IntPtr hServer,
uint sessionId,
WTS_INFO_CLASS wtsInfoClass,
out IntPtr ppBuffer,
out uint pBytesReturned
);
Note that sessionId
is a DWORD
which is an untyped 32 bit integer.
