Use the template below then delete this header:
C# Signature:
[DllImport("advapi32.dll")]
public static extern bool LogonUser (String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
VB .NET Signature:
Declare Auto Function LogonUser Lib "advapi32.dll" (ByVal lpszUsername As String, ByVal lpszDomain As String, ByVal lpszPassword As String, ByVal dwLogonType As Integer, ByVal dwLogonProvider As Integer, ByRef phToken As IntPtr) As Integer
User-Defined Types:
None.
Notes:
It is very important to know which LOGON type you need. LOGON_NETWORK will allow access to network resources, while LOGON_INTERACTIVE will not. This will cause you hours of consteration if you don't pay attention to it.
To make this useful, you will also need to implement DuplicateToken.
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.

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.

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.

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.
