I have a service running in Windows 7. In Windows 7 all services run in Session 0. From that service I want to create an interactive user session (in a session other than Session 0) and start an application in that session. My problem is that when I call LogonUser to start an interactive user session and then use CreateProcessAsUser to start the application the application ends up running in Session 0.
All of my code is C#.
Here is the relevant code:
[DllImport("advapi32.dll", SetLastError=true)]
static extern bool LogonUser(
string principal,
string authority,
string password,
UInt32 logonType,
UInt32 logonProvider,
out IntPtr token);
[DllImport("advapi32.dll", SetLastError=true)]
static extern bool CreateProcessAsUser(
IntPtr hToken,
string lpApplicationName,
string lpCommandLine,
IntPtr lpProcessAttributes,
IntPtr lpThreadAttributes,
bool bInheritHandles,
int dwCreationFlags,
IntPtr lpEnvironment,
string lpCurrentDirectory,
ref STARTUPINFO lpStartupInfo,
ref PROCESS_INFORMATION lpProcessInformation);
IntPtr token;
LogonUser("UserName", ".", "Password",
LogonTypes.Interactive,LogonProviders.Default, out token)
<code to impersonate user>
string hd = Environment.ExpandEnvironmentVariables("%USERPROFILE%");
IntPtr envBlock = IntPtr.Zero;
CreateProcessAsUser(token, "PathToMenu.exe",
NORMAL_PRIORITY_CLASS |CREATE_UNICODE_ENVIRONMENT,
"WinSta0\\Default", hd, envBlock, "Menu");
Can anyone tell me what I'm doing wrong?
