Frequently asked questions

What code analyzers are used in addition to Visual Studio?

What to do if the check update tells that the SSL certificate is wrong or expired?

The software verifies the validity of the certificate of the update server in addition to the SHA-512 checksum of the installation file before downloading and running it.

You can manually check the latest version available online in case of problem.

What to do if the application does not work normally despite restoring settings?

Use the Start Menu link:

Ordisoftware\Hebrew Letters\Reset Hebrew Letters settings

This will erase all settings as well as those of old versions, which should resolve issues if there is a conflict, otherwise please contact support.

What is the Windows double-buffering?

When enabled, this will speed up rendering of the main form when it is displayed, but it may cause a slight black flicker.

When disabled, top menu and some controls painting may cause latency, and dynamic items can be generated slowly the larger the number.

What are command line options?

  • Change interface language (does not change the meanings of letters unless restoring them):

Ordisoftware.Hebrew.Letters.exe --lang [en|fr]

  • Analyze a word in Hebrew unicode chars or else Hebrew font chars like "בראשית" and "ty>arb":

Ordisoftware.Hebrew.Letters.exe --hebrew [word]

Or without any other option:

Ordisoftware.Hebrew.Letters.exe [word]

All diacritics are removed and if the word can't be processed it is set to empty.

If any Hebrew unicode chars is present, all non-unicode are removed, else Hebrew font chars are used and all non-font chars are removed.

This program does not use IPC intercom yet since multiple instances can run at the same time.

How to run a word contextual analysis from any application such as browser or text editor?

It is possible to use AutoHotKey to define for example this Shift + Ctrl + Alt + H command on a selected word:

  clipboardOld := ClipboardAll
  ControlGetFocus, ctrl
  Send, ^c
  sleep 100
  word := Clipboard
  Clipboard := clipboardOld
  appPath := "C:\Program Files\Ordisoftware\Hebrew Letters\Bin\"
  appExe := "Ordisoftware.Hebrew.Letters.exe"
  sleep 200
  Run %appPath%%appExe% "%word%"
