Sample Code:
Public Shared Function OpenAppAsUser(ByVal username As String, ByVal domainname As String, ByVal password As String) As Boolean
'The Windows NT user token.
Dim lpAppName As String
Dim appExe As SR.[Assembly]
Dim pi As PROCESS_INFORMATION
Dim si As STARTUPINFO
Dim fResult As Boolean
Dim dwCreationFlags As Integer = Nothing
Dim lpCommandLine As String = Nothing
Dim lpEnvironment As IntPtr
Dim lpCurrentDirectory As String = Nothing
Dim ret As Integer
' call the Win32 API to open the application under the userID passed in
' Implicit Integer to Boolean conversion. CreateProcessWithLogonW returns 0 (False) when it fails.
fResult = CreateProcessWithLogonW(username, domainname, password, LOGON_WITH_PROFILE, lpAppName, lpCommandLine, dwCreationFlags, lpEnvironment, lpCurrentDirectory, si, pi)
' if the logon fails then we need to generate an error
If Not fResult Then
' get the last error from Windows
ret = Marshal.GetLastWin32Error
' if the userid, password, or domain is bad we can display a friendly message
If ret = 1326 Then
MessageBox.Show("Invalid UserID or Password entered. Please try again.", "Logon Error")
Return False
Else
' the error code is unexpected so throw an exception to be logged.
Dim retMsg = GetErrorMessage(ret)
Throw New MAE.BaseApplicationException("Error occurred: " + ret.ToString() + " - " + retMsg)
Return False
End If
End If
Return True
End Function

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.
