  2. Re: Restarting a web app process when a critical error isn't a critical error

    I'd forgotten about that, though the error does say it's "unrecoverable"!

    I did first check in SSMS to make sure the web app server could connect to the SQL server, and when that connection was...
  3. Restarting a web app process when a critical error isn't a critical error

    This morning we had a customer report no one could log into the web app. They were getting the following error 12289 message:

    Re: I hate CODEMAST

    That was the first thing I checked; it shows 254. Of course my CODEMAST.FD is fine, it's the one in C:\Program Files (x86)\DataFlex 19.1\Lib that is screwed up. It's dated 5/17/2021. So it has...

    Re: I hate CODEMAST

    I didn't have time to fully explain the problem, but here it is: in cCodeMaintOpen_Mixin.pkg (19.1) for some reason Codemast.file_number is 208 (the old #) rather than the 254, and this is resulting...

    I hate CODEMAST

    Re: Barcode Scanner

    Any tips for troubleshooting? On both my phones it doesn't seem to work, tapping on the Start scanner button expands the "Scanner" box, but there is nothing in it. Should I get a question asking if...
  8. Re: Why might a tab view page refuse to re-open?

    This is a shot in the dark, but a couple weeks back we had a customer with a view that didn't open. Turns out it was open, it just was not visible. We could navigate, press [F4] to activate look...

  11. Re: Suggestion: More flexible finds (SQL backends)

    If the primary table for the lookup is ORDERHEA, you can't use CUSTOMER.NAME in the ordering of the lookup. I don't think you can do what you want in your grid example without using a SQL view and...
  12. Re: Are file associations really useful for source files?

    Well it actually happened in (gag!) WinCVS, which has a nice feature to customize the right click menu so I've banished the "Open" option.
  13. Are file associations really useful for source files?

    And should it work differently?

    Re: DF does not like high res screens.

    Thanks Wil!

    That worked, as did this:
