ImpersonateLoggedOnUser (advapi32)
.
C# Signature:
[DllImport("advapi32.dll", SetLastError=true)]
static extern TODO ImpersonateLoggedOnUser(TODO);
VB Signature:
Declare Function ImpersonateLoggedOnUser Lib "advapi32.dll" (ByVal hToken As Integer) As Integer
The last param in LogonUser (phToken) can be declared as Integer to work with the following VB.Net sample. The key is making sure it is ByRef vs ByVal.
Sample Code:
Public Sub Logon(ByVal strUser As String, ByVal strPassword As String, ByVal strDomain As String)
Dim lngLogonType, lngLogonProvider, lngTokenHandle As Integer
Dim blnResult As Boolean
blnResult = LogonUser(strUser, strDomain, strPassword, _
lngLogonType, lngLogonProvider, _
lngTokenHandle)
If blnResult Then
blnResult = ImpersonateLoggedOnUser(lngTokenHandle)
CloseHandle(lngTokenHandle)
Else
MsgBox("Error logging on")
End If
End Sub

The LogonUser function attempts to log a user on to the local computer. The local computer is the computer from which LogonUser was called. You cannot use LogonUser to log on to a remote computer.

ByRef is a VB keyword that specifies a variable to be passed as a parameter BY REFERENCE. In other words, the pointer to the variable is passed and any change to its value made within the function or sub will change its value outside the function/sub.

ByVal is a VB keyword that specifies a variable to be passed as a parameter BY VALUE. In other words, if the function or sub changes the value of the internal variable, it does not change the value of the external variable that was passed to it.
