Hi Josh,
Thank you for your inquiry!
I apologize for the repeat message but I want to ensure communication of support of DMCoreX for the Hyland Community.
Depending on version of OnBase you are on, I would recommend migrating your VBScripts to Unity Scripts. The biggest reason is that the end of life of DMCoreX API is targeted for December 31, 2014 and has already been marked as deprecated. DMCoreX API is being replaced by Unity API. More information about Product Support Lifecycle & End of Life Schedule can be found here.
In regards to your question, I would suggest not to retrieve documents directly from the OnBase disk groups but to retrieve the document through the API interface. The are several reasons for this but most importantly:
1) Data integrity - This will prevent code from accidently moving or deleting a file from disk group.
2) File Format of requested document - There are instances where the document stored in the disk group may not be want you expect or have a different file extension. An example of this are E-Forms. In the disk group, we store an HTM file however if you open up the HTM file you will only see the post data of the form and not the HTML itself. Another example would be a COLD file. OnBase stores the entire COLD index file in the disk group and OnBase will know how to parse the file to retrieve a specific document.
With that being said, I would recommend leveraging IOBXPresentationServices for document retrieval purposes. You can then obtain the IOBXDocumentDataProvider object to then call IOBXDocumentDataProvider::GetDocument() method.
To answer your question directly below is the code to get the relative path for a specific page of a document.
Function Main(oSession, oDocument) ' Obtain the Page Collection Dim oDocumentPageCollection Set oDocumentPageCollection = oDocument.Pages Dim i ' Iterate through the page collection For i=0 to oDocumentPageCollection.Count-1 Dim oDocumentPage Set oDocumentPage = oDocumentPageCollection.Item(i) ' Get the pages relative path to as it is stored in the disk group Dim strRelativePath strRelativePath = oDocumentPage.RelativePath Set oDocumentPage = Nothing Next
Please note that the ability to retrieve the document physical path is not available in Unity API and uses the approach I recommended above by using the API interface to retreive a document from OnBase. Below is a code snippet of retrieving a document through Unity API. It assumes the implementer is asking for the document back as an image (TIFF)
using(PageData pageData = app.Core.Retrieval.Image.GetDocument(args.Document.DefaultRenditionOfLatestRevision)){ string tempFilePath = String.Format(@"{0}\{1}.{2}", System.IO.Path.GetTempPath(), args.Document.ID, pageData.Extension); Hyland.Unity.Utility.WriteStreamToFile(pageData.Stream,tempFilePath);}I hope this helps!
