Hi there,

I want to move the document to second document library
(portal level) as soon as its been submitted (insert as
eventListType) to first document library (WSS level).
I do have assembly registered at GAC. I am able to add the
Name, version and PublickKeyToken to the advance settings
of document library.
Error I see in event viewer is:
------------------------------
Unable to instantiate event handler
(assembly "WorkFlowC,Version=1.0.1753.30479,Culture=Neut ral
,PublicKeyToken=b87bf9d85439e671",
class "WorkFlowC.Engine1"), or report event for "Working
docs/spnewlisting.aspx" in "Working docs". Error in the
application.

------------------

Please see the code below.

using System;
using System.Windows.Forms;
using System.Security.Principal;
using System.Runtime.InteropServices;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Portal.SingleSignon;

namespace WorkFlowC
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public class Engine1:IListEventSink
{
public void OnEvent(SPListEvent listEvent)
{
// Call MSSO

string[] strCredentials=null;
Credentials.GetCredentials
(Convert.ToUInt32
(1),"WorkflowC",ref strCredentials);
string User = strCredentials[0];
string Domain = strCredentials[1];
string Password = strCredentials
[2];

//Create new context
WindowsImpersonationContext
windowsContext = CreateIdentity
("mgaur","AU","test1").Impersonate();

//Get event objects

SPWeb eventSite =
listEvent.Site.OpenWeb();
SPFile eventFile =
eventSite.GetFile(listEvent.UrlAfter);
SPListItem eventItem =
eventFile.Item ;

//Dtermine if document submitted

if(listEvent.Type ==
SPListEventType.Insert)


//Move the document
eventFile.MoveTo
("http://dais-net:7554/test/Forms/AllItems.aspx",false);


windowsContext.Undo();

}



protected static WindowsIdentity
CreateIdentity(string User, string Domain, string Password)
{
// The Windows NT user token.
IntPtr tokenHandle = new IntPtr(0);

const int LOGON32_PROVIDER_DEFAULT
= 0;
const int LOGON32_LOGON_NETWORK =
3;

tokenHandle = IntPtr.Zero;

// Call LogonUser to obtain a
handle to an access token.
bool returnValue = LogonUser(User,
Domain, Password,
LOGON32_LOGON_NETWORK,
LOGON32_PROVIDER_DEFAULT,
ref tokenHandle);

if (false == returnValue)
{
int ret =
Marshal.GetLastWin32Error();
throw new Exception
("LogonUser failed with error code: " + ret);
}

System.Diagnostics.Debug.WriteLine
("Created user token: " + tokenHandle);

//The WindowsIdentity class makes
a new copy of the token.
//It also handles calling
CloseHandle for the copy.
WindowsIdentity id = new
WindowsIdentity(tokenHandle);
CloseHandle(tokenHandle);
return id;
}

[DllImport("advapi32.dll",
SetLastError=true)]

Hi Manish,

After reviewing your code, I'd suggest you can comment the code line
"Credentials.GetCredentials(Convert.ToUInt32(1),"W orkflowC",ref
strCredentials);"

Since you have performed the impersonation, from my view, this line is
unnecessary.

From the error, it appears that WSS can't instantiate the assembly. Please
ensure your assembly version code of document library is the same to the
one in the GAC.

Look forward to your trouleshooting result!

After removing the line I got the below error

Unable to instantiate event handler (assembly
"WorkFlowC,Version=1.0.1754.24492,Culture=Neutral, PublicKeyToken=b87bf9d85439e671",
class "WorkFlowC.Engine1"), or report event for "Working
docs/ProjectSite.rtf" in "Working docs". Object reference not set to an
instance of an object.

Hi Manish,

After commenting that line, have you also commented the three line below?
string User = strCredentials[0];
string Domain = strCredentials[1];
string Password = strCredentials[2];

They will use the returned value of the first commented line.
(Credentials.GetCredentials(Convert.ToUInt32(1),"W orkflowC",ref
strCredentials);)

Expect for your reply!

Thank Wei, It did work.
But I am unable to move the custom property (using hashtable) from document
library to list.

Hi Manish,

Document library, in fact, is vastly different to other lists when we want
to perform the copy operation. In other list, we can only pass the list
value from one to another list's items. Since Document library is based on
files, it is essentially one file copy operation. The SDK page below
introduces the sample code for you:
CopyTo(String, Boolean) Method
http://msdn.microsoft.com/library/de...us/spptsdk/htm
l/tsmSPFileCopyTo2.asp

So I think there is no need to use the hashtable for the copying. Please
feel free to let me know if you have any question.
