Frequently asked questions

How to install SQlite ODBC Driver?

The setup installs:

In the event that an error message indicates that a DLL file could not be copied, it is usually due to the fact that an application using this driver already installed is running and is blocking the file. You can ignore this error or close the application in question and restart the installation to obtain a driver update.

What to do in case of ODBC datasource connection error?

The application tries to register an ODBC DSN to the registry but in case of problem run "C:\Program Files\Ordisoftware\Hebrew Letters\Register ODBC.reg" or open the ODBC datasource manager (Admin tools in Windows' Control panel) and create a user datasource named "Hebrew-Letters" for "SQLite 3 ODBC Driver" with "Database Name" sets to:

"%USERPROFILE%\AppData\Roaming\Ordisoftware\Hebrew Letters\Hebrew-Letters.sqlite"

Watch the video.

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. This certificate is normally updated within the two months of its annual expiration and a new version is released. You can manually check the latest version available online in case of problem.

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.

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%"
