CHANGES FOR VERSION 6.31.0 (as compared to 6.30.0)

  1. AFL: Access violation in PercentRank when period is wrong. Now error 52 is displayed instead.
  2. AFL: InternetPostRequest now silently (or with warning 507 under debugger) returns NULL handle instead of error when remote server responds with HTTP Status 50x
  3. Analysis: manual column re-sorting could be bit off if scientific output format (xxxEyyy) was used with different exponents. Fixed.
  4. ASCII importer now handles LastSplitRatio of X:Y where X and Y are 1...32767 (previously only 1..127)
  5. Batch: added "add results to watchlist" action / WatchlistAddResults
  6. Batch: added "clear watchlist" action / WatchlistClear
  7. Batch: added "comment" action
  8. Core/DB: fixed access violation when all data were removed while QuickData was turned on
  9. DebugView: eliminated some internal messages from DebugView output (from release version)
  10. InternetPostRequest - even if URL started with https, previous version wanted to connect to port 80, instead of 443. Fixed.
  11. UI/Listview: since 6.28 exception could occur if single cell text length exceeded 1024 characters. Fixed.
  12. When database is empty, ticker box displays grayed text instead of blank or reminiscent of previous database symbol

This thread is continuation of the discussion from AmiBroker 6.29.0 BETA released


Note to users who have Avast anti-virus software working in the background.

Based on personal experience, you have to disable Avast when installing Amibroker 6.31.0 Beta. When I tried to install with Avast enabled, I encountered blue screen of death the moment I double-clicked on the installation file. On the third try of installation, I disabled Avast and the installation succeeded.

I am using Windows 10.

Thank you to Tomasz for the new beta release.

Both files are 100% clean.

Avast Anti-virus messes up with OS, see: You should contact Avast to fix their AV.

Other interesting story: Bad Image (0xC000020) error - McAfee gone mad

Just use built-in Windows Defender / Microsoft Security Essentials. It is as good as any other AV comes built-in and at least does not blow up your system.
