According to lapi documentation if you obtain the objectinfo by using the call GetObjectInfo you are returned an assoc called Objectinfo.Basically you change in that assoc CreatedBy and Userid and update that by using UpdateObjectinfo.Sorry havenot tried this but many other things with UpdateObjectInfo

Todd_Pinel

Hey Guy :)Appu is correct. Just create an assoc and set a key in that assoc named "CreatedBy" to the userid in question and then pass that into UpdateObjectInfo.Heres a C# code snippet:int newUserId = 111222333; //user in questionint objectId = 23345677; //object in questionLLValue updateInfo = (new LLValue()).setAssocNotSet();updateInfo.add("createdby", newUserId);LAPI_DOCUMENTS doc = new LAPI_DOCUMENTS(session);if (doc.UpdateObjectInfo(0, objectId, updateInfo) == 0){//success}else{//failed}

The code looks good and I’m sure itworks; however, can I just chime in with a short warning?

The CreatedBy field is really an integralpart of the history of your organisation’s knowledge and I’dsuggest that you should have an extremely good reason for overriding it.

For example, if I create a document inLivelink and then some years later I leave the organisation, there is a recordthat I created that document. On the other hand, if someone were to change theCreatedBy field of that document to the person hired to replace me (yes I know,nobody could replace me J ) then it appears that the new person created the document and notme, and s/he may not be too pleased about it. Nor might the auditors, lawyersor compliance officers.

Just something to consider.

Hey Guy

Appu is correct. Just create an assoc and set a key in that assoc named "CreatedBy" to the userid in question and then pass that into UpdateObjectInfo.

Heres a C# code snippet:

int newUserId = 111222333; //user in question
int objectId = 23345677; //object in question

LLValue updateInfo = (new LLValue()).setAssocNotSet();

updateInfo.add("createdby", newUserId);

LAPI_DOCUMENTS doc = new LAPI_DOCUMENTS(session);

if (doc.UpdateObjectInfo(0, objectId, updateInfo) == 0)
{
//success
}
else
{
//failed
}

Message from Carsten Kulms via eLinkIn addition to Howard's remarks I would like to note that caution mustbe paid also due to the UpdateObjectInfo funtion does not validate thepassed user id values.

Guy_Turton

Thanks for all your help, and Yes the code works .... well partially. The created By gets updated correctly, however, the owned by does not.Here's my vb.net code:Public Function UpdateDocumentCreatedBy(ByVal docs As LAPI_DOCUMENTS, ByVal docID As Integer) As Boolean Dim request As LLValue = New LLValue().setAssocNotSet() Dim status As Integer = docs.GetObjectInfo(VolumeID, docID, request) request.add("OwnedBy", OwnedByID) request.add("CreatedBy", CreatedByID) status = docs.UpdateObjectInfo(VolumeID, docID, request) If status.Equals(0) Then Return True Return False End FunctionAlso, thanks for the warnings about changing Created By etc. This is actually a new doc being added through our web service via a vender ap that is running under a separate process. Instead of the process being the owner/created by, we would like the user who is actually adding the doc to be those values.Another quick question: Can you update the created by/ owned by using CreateObjectEx? I know you can update the comments there, however I tried updated the created by etc there and it didn't work.It would save from having to call another method to update those values, if I could do it all at once.Thanks

Message from Carsten Kulms via eLinkThe "owned by" or "owner id" parameter is named "UserID" (seedescription of the ObjectInfo Attributes Assoc).> Instead of the process being the owner/created by, > we would like the user who is actually adding the doc > to be those values.Maybe it is an option to use the impersonation feature of LAPISession.This require you have the username of the real WebService user at handwhen calling the create doc function. (And the technical account needsproper privilege.)

And the user being added to "CreatedBy" does have an account with the same ID already on the target Livelink system...? Sorry to ask such a question but sometimes it's something simple like this that lies at the heart of the problem. I'm not really sure that would make a difference when you're pushing the value in via code...

Todd_Pinel

This is the exact design I use in a web service as well, and it works quite nicely.The impersonation on the session takes care of all the user specific values for you.The one attribute that poses an issue, and for logical reasons (maybe?) is the created date. This can be changed using the UpdateObjectInfo after the document is created, but I have not found a way to override this using CreateObjectEx.Let me know if you'd like more code samples.

Guy_Turton

Yes the account does exist in Livelink.OK, got it working. Instead of using the key "OwnedBy", use "userID". This was from Todd's post earlier up in the Thread. Thanks Todd!request.add("userId", OwnedByID)Thanks

Hello Guys,

Would you please help me in where I am going wrong, I have tried the same way for updating Createby and OwnerID....

I have tried the same in JAVA

/////// ------ Code snippet for updating the createdby and ownerid

    UpdateInfo.add("CreatedBy",1000);
    UpdateInfo.add("UserID",1000);
    System.out.println(UpdateInfo);
    int upstat ;
    upstat = doc.UpdateObjectInfo(parentVol, parentID, UpdateInfo);
    System.out.println(upstat);
    if(upstat == 0)
    {
    System.out.println("Success");}
    else {
    System.out.println("failed");

}

/// ----------- but getting the error message like here below

Basically the code snippet looks right.The error " get(name) not implemented for this datatype" can be causedby several issues -- you may like to search this forum for this errormessage and possible diagnostic measurements. (First step: check theserver logs, with "detailed thread logging" enabled.)In your case I can imagine that something is wrong with the passed"UpdateInfo" object; what type is it?

Alexander_Pachipala

Hi,

Thanks for your response,

I have tried looking logs and KC for the error, but no findings yet.

///UpdateInfo is a LLValue

LLValue UpdateInfo = ( new LLValue() ).setAssocNotSet();

Any suggestions would be helpful..

Thanks and Regards,

Alex

Carsten_Kulms

I meant that you may run a search in KC (in the LAPI community) for e.g."get(name) not implemented".The following are two hits:However, the UpdateInfo is right (it might be important that its defaultis set to "NotSet").Well, seems you have to check your Content (fka Livelink) Server'sthread logs; watch out for trace...out files also. (Ensure you have atleast "Detailed Thread Logging" enabled at the server!)

Kevin_Bailey

I seem to recall that I had the same problem… to fix it, Idid a work-around by doing a GetObjectInfo to pre-populate UpdateInfo:

private int setfolderrootperms( int volumeID,int nodeID, int usergroupID, int permission, int index, int ugID )

{

LLValue Request = (new LLValue() ).setAssocNotSet();

Request.setAssocNotSet();

ret =llDocs.GetObjectInfo( 0, nodeID, Request );

Request.add("UserID", usergroupID );

ret =llDocs.UpdateObjectInfo( volumeID, nodeID, Request );

}
