[Syntax]
C++: HRESULT RevertToSelf()
Visual Basic: RevertToSelf()

Remarks

This method logs off current impersonated user with ImpersonateUser method. Normally, ASP/ASP.NET applications run under the security context of IUSER_MACHINENAME user, this user doesn't have enough permission to access all files on server. Therefore, many file operations would be failed in ASP/ASP.NET applications such as ExportFile, SaveAttachment, ImportFile and so on. ImpersonateUser method provides a way to run your ASP/ASP.NET applications under administrator or any other user so that POPMSG object has enough permission to access files.

Usage Example

Dim oMsg
Dim user, password

oMsg = Server.CreateObject("ANPOP.POPMSG")
user = "administrator"
password = "ad1234"

If oMsg.ImpersonateUser( user, password, "" ) = 0 Then 'logon this user
  Response.Write "Impersonate user succeeded"
Else
  Response.Write "Impersonate user failed"
End If

oMsg.RevertToSelf 'log off this user and run oMsg with original user

Dim oMsg As ANPOPLib.POPMSGClass()
oMsg = Server.CreateObject("ANPOP.POPMSG")

Dim user, password As String
user = "administrator"
password = "ad1234"

If oMsg.ImpersonateUser( user, password, vbNullString ) = 0 Then 'logon this user
  Response.Write( "Impersonate user succeeded" )
Else
  Response.Write( "Impersonate user failed" )
End If

oMsg.RevertToSelf() 'log off this user and run oMsg with original user

ANPOPLib.POPMSGClass oMsg = 
                 (ANPOPLib.POPMSGClass)Server.CreateObject("ANPOP.POPMSG");
string user = "administrator", password = "ad1234";

if( oMsg.ImpersonateUser( user, password, null ) == 0 ) //logon this user
  Response.Write( "Impersonate user succeeded" );
else
  Response.Write( "Impersonate user failed" );
  
oMsg.RevertToSelf(); //log off this user and run oMsg with original user
