Modifying CreationDate and other file attributes

I'm working on a webservice which will be used to upload multiple documents and download multiple documents through the use of the LL EWS. From recent discoveries, the FileAtts class is of no use and doesn't change any of the file-attributes. I've also checked if the Attachment class is able to change any of the attributes, which it isn't. This presents the following problem: Users won't be able to upload documents with the correct CreationDate. The date will be set to the current date instead(why would anyone make the FileAtts class and the Attachment class when where nothing but the file-content is used). Does anyone have a solution or a suggestion as to how to be able to do this with the current webservices or in another way besides making a webservice of our own which connects to the database itself?

Changing the special system properties freely should be shunned. You should try first to design your solution without resorting to that. Creation date, creator, last modification date etc. should reflect the operations done with the node in Livelink; not the status of the file in the system where it originated from (file system, SAP, ...). An example would be storing the extra information from the document origin in custom attributes.

There has been a discussion about this topic started already - you can have a look at https://knowledge.opentext.com/go/17637409.

Here is the code i've been using. It's influenced by an example i think i found in this forum.

private void UploadBtn_Click(object sender, EventArgs e)
        {
            try
            {
                openFileDialog1.Multiselect = false;
                openFileDialog1.Title = "Upload document";
                openFileDialog1.ShowDialog(this);

                FileInfo file = new FileInfo(openFileDialog1.FileName);

                int parentID = 2000;
                string comment = "Uploadtest of document with contentservice";
                bool advancedVersion = true;
                DocumentService.Metadata metadata = null;

string docContext = documentClient.CreateDocumentContext(documentAuth, parentID, file.Name, comment, advancedVersion, metadata);

                FileAtts atts = new FileAtts();
                atts.CreatedDate = file.CreationTime;
                atts.FileName = file.Name;
                atts.FileSize = file.Length;
                atts.ModifiedDate = DateTime.Now.AddYears(10);

                FileStream fs = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read);

                FileInfo file2 = new FileInfo(openFileDialog1.FileName);
                string objectID = contentClient.UploadContent(contentAuth, docContext, atts, fs);

                StatusLbl.Text = "Uploaded document ID = " + objectID;
            }
            catch (Exception ex)
            {
                StatusLbl.Text = ex.Message;
            }
        }

The FileAtts does nothing. I've tried setting the different properties of the atts object but none of them has any effect on the file attributes of the uploaded document.

Hi, Andre.

How are you checking the file date and time of the uploaded document? Through the Livelink/Content Server UI?

Thanks,

Scott

I've made an application similar to the LLTreeView demo. My application is using the webservices as well. I've tried setting the attributes through the Attachment class and the FileAtts class without any result. Fortunately, i've just received a message from one of the guys in charge of the project who says that my webservice will operate with the current date when uploading. But we have 2 guys working on a migration who need to be able to set the creation date and userid. Is it possible through the existing webservices or do they need to use the Lapi-library?
