"No more files" error

"No more files" error in Paradox Tables topic (part of our Corel Paradox / ObjectPAL Coding group).

Quick Search: "No more   "No more files"

Upgraded a win 7 box to win 10. 

Using a win 7 client.  Now recieve the error:

Cannot open: :dbx:table.db

No More files.

Table: table.db

Table: \\earth\database\xxx

Happens both manually and programatically.  Can usually get it to work if I quickly try to access same table/query again.  The longer I wait before retrying the greater the chance it will error again.

I see some similar issues online after Win 10 updates.

Do we have a fix?

over the past year, I've seen a number of weird file-access errors on Win10.. I haven't seen this particular one, but it fits the pattern

no real fix, other than a beboot, and the next win10 update.. scary stuff

Thinking a few options.

  1. Host Paradox DB on a Linux server
  2. Host DB on a dedicated NAS drive
  3. Port DB to MySQL (not even sure MySQL will work with pdox now)

I need to insulate this db against Microsoft updates.

Whatcha think?

Is the database currently hosted on the local win 10 computer?  Or a windows server? (What OS?)

Clients are win 7/10.

What version of Paradox?

I had a very similar issue on Ver 8.  (Before Win 10 killed it)  The issue was related to the BDE Version that was running (which is really related to the SMB protocol that is being run under the covers,  so you might look into that on the Win 10 server).   Anyway,   The pre-installed BDE version(contained in the PDOX 8 install) worked forever,  then I started seeing the error pop up. There were some tables that would open,  others that just flat refused.  My issue was usually tied to the installation of a new server (Small Business 212, for one)

After installing BDE 5.2,  the problem went away.

Let me know if you want to try BDE 5.2,   I can probably scrounge up a url for the download.

Pdox 11  BDE 5.2

On the interesting side I did get MySQL working on server and pdox client.  However a conversion to SQL does not excite me.

I am thinking linux box/NAS.

Re: Paradox/BDE No More Files error.

I have tried a workaround with some success.  

Do a loop testing IsTable(tableName) before trying to open the table/query.  

I will post the code later after more testing, but it seems to be working.

isTable and isFile force the file buffers to flush, so that makes sense.. and really can help as a warning here, if you're getting "false" returns, when you know you shouldn't be
