Hi,

I am uploading a directory of files to DMX using EntriesController.SimplifiedUpload. All is working fine, I can see the files in DMX, but for some reason all files have the same MD5Hash value even when they are all different. Is there anything I need to do to make sure the MD5Hash value is correct?

Just forgot to mention:
DNN 4.6.2
DMX 4.3.2

Hi Peter,

Thanks for your reply but since we need the MD5Hash (to detect multiple uploads of the same file under a different name) we implemented our own code with the following logic:

1. Calculate MD5Hash with DMX.Common.Hash.ComputeFileHash(filename)
2. Check if entry exists in DMX_Entries within a collection and any subcollections on the basis of the filesize, filetype and MD5Hash (developed our own stored procedure for it)
3. If it does not exists
   1. upload document to DMX with SimplifiedUpload
   2. use the EntryId returned from the previous step to get the entry with EntriesController.GetEntry
   3. set the MD5Hash field to the value calculated in step 1
   4. call EntriesController.UpdateEntry

This works ok for us and as expected the MD5Hash is the same as when the document was uploaded using the "New Item..." dialog. There is a small overhead so it would be better if SimplifiedUpload would set the MD5Hash in a future release.

Thanks,

Marc
