  Hi

  I have Error DBFNTX/1001 Open error: abc.DBF (DOS Error 4)

  In dos i have to use Files=230 in config.sys but vdos does not allow it so how can i do make it working.

  Thanks

  • 

    vDos always supplies the maximum of 255 global DOS file handles.
    Could it be that you’re using a Clipper compiled program?
    If so, add SET CLIPPER=F:100 before starting the program to autoexec.txt and see if that helps.

  Hi
  But if it still doesn’t work ?
  I’m quite sure that it is Clipper compiled program and I’ve added propperly SET CLIPPER=F:100 before starting (autoexec.txt or/and in bat before exe). What is more perverse the same application at the same configuration on the some computers works, but on the other ones doesn’t
  Could you help ?
  Regards, Darius

    If you copy the vDos directory (vDos.exe, autoexec.txt and config.txt) of a working configuration to another PC, that one is guaranteed to work. Given of course the same Clipper startup and data is used.

    If the vDos files are the same, it would have to be the Clipper startup, that’s done locally?

  After some hours of fight it’s a bit different matter then I wrote before. There’ re not exactly the same app on every PC, it’s the same producer ones, every compiled in clipper, but different exe file…

  So, now the problem is that some clipper’s apps doesn’t «see» phrase SET CLIPPER=F180 added to autoexec.txt on every computer.

  Could you help ?
  Thanks a lot, in advance, Darius

    Those executables perform the same functionality, so you can exchange a “bad” with a “good” one?

    Else I would need a test environment from you in which SET CLIPPER=F80 isn’t accepted, and DOS Error 4 is generated.

  hi jos, i’ve been running vdos for more than 2 years now; it has been a blessing for the app i support; as of one year ago, i’ve had installed vdos on several win-10 x64 pc’s, and have been working fine up yo yesterday, in some instances of the app i’m gettin a vdos — exception (image included), please guide my efforts to solve this matter; i’ve been unable to do so

• 

  i can’t seem to include the image, sorry;it reads exactly like this:

  vDos — Exception

  (X) PSP file table (JFT) is messed up

  (ok button)

  i installed a fresh copy of vdos.exe oct/19/2014 19:40, and the event in error re-ocurred

  some help would be very appreciatted

• 

  i think that a limitation in the net resource in the form of space or quantity of files, may cause this problem; this came to my attention when i tryed to copy a file component of the application in the same «disk» and it gave an error message stating that «there was no space available» (immage included)

  If I understand correctly, you used, and still use version 2014.10.19. Until yesterday no problems, and then out of the blue this exception.

  What if you use the latest 2017.08.01 version?
