First Time Launch

The first time you start the TVA Weather Reader after installing it you will need to configure it. You will be prompted to enter a Instance Name.

The instance name is arbitrary - it can be any name you like such as Live, Production, Test, Jose, GoJaysGo. It is simply a label to associate with a specific set of configuration values. This is helpful in situations where you have multiple tickers that you want to update. This enables you to do so without running multiple copies of the reader.

Configuration

The reader requires some information about the data source and the target Tick-It database before it can begin running.

Instance name is an arbitrary name for the settings   The Super Ticker The Chameleon MySQL section is pre-filled with defaults that will likely work with your Tick-It or Super Ticker database Chameleon database  Default user id is Updater     The data source is is your Microsoft SQL Server database.   You can specify the server as an IP or as a name. The user id and password are optional if the logged in Windows account has access to the SQL Server database.

You can force an immediate update by pressing the Start Now button when enabled.

In this example the reader was started by pressing the start now button and the status text box has been updated with a message to reflect this.

Locations

This tab of the application provides a list of the locations that it is working with.
It is populated during the first execution and updated each time it runs.

This list is mostly not editable. You cannot manually add or delete or edit any of the location details. However you can delete locations that are no longer part of the data source.

Remove Locations

You can remove locations that are no longer valid (version 1.0.6). However if you remove a location that is still part of the data source - when the reader runs again it will re-add the location.

To remove the locations that are no longer valid:

1. Select the Locations tab
2. Click on the location you wish to remove.
3. Press the Delete key
4. Confirm removal when prompted

Verbose Logging Option

You can choose to enable an option that provides greater audit details for the reader's operation. Activate it using the Help menu - Logs - Verbose Logging option.

You generally enable this for a short time while debugging an issue and then disable it when you no longer need it.

French (français)

The application includes an option to force the use of French (français) in the UI.

NOTE: French text has been provided using a best-guess translation and may not be perfectly correct for all texts.

Select the Français option from the Help menu item.
Some of the UI elements will automatically convert to français while others will only convert when you restart the reader.

NOTE: that the application may automatically use French if that is the default language of the machine it is installed on. 

Data Mapping

The data for the TVA weather app comes from a custom Microsoft SQL Server database created and maintained by TVA.
