Multi-Language Add-In for Visual Studio

Quick Tour (Windows Forms)

Activating the Multi-Language Add-In

After you have installed the Add-In, there will be a new menu item in the Tools menu in Visual Studio.

This menu item activates the Add-In and shows it in a tool-window. You can dock this window at the side of the main Visual Studio window, or drag it into a tab group, like other tool windows in Visual Studio. It's probably best to place it at the bottom, in a wide format.

Selecting a project

A Visual Studio solution may contain multiple projects. However, the Multi-Language Add-In always works with a single project. To get started, you must first select the project. There are two ways to do this.

from a dialog	When you select the Add-In from the tools menu, it will probably show a list of the projects in a dialog. Simply select the project and click on OK. This dialog can be disabled, so if somebody else has already worked with the Add-In, it might not appear.
from a drop down list	At the top of the Add-In's main window, just below the toolbar, there is a drop down project list You can select a different project at any time from this list.

Initialising the project for localization

When you select a project for the first time, you must specify what the original language of the project is. The Add-In will show a list of the languages supported by Windows.

Select the original language and click on OK.
(The buttons below the list change the way the list is displayed. In particular, the button English simply shows the language names in English. It does not select English in the list).

This dialog will probably be followed by second dialog, with options for scanning the project. Just click on OK to accept the default options.

The Add-In will now add two new files to your project.

Scanning the project

The Add-In will now scan the project. This is performed in two phases:

• scanning controls
• scanning source code

In the first phase, the controls in each Form and each ))UserControl(( are scanned for properties with the localizable attribute. In the second phase, the source code of the project is scanned for texts which may require translation.

The results of the scan are displayed in two separate grids in the Add-In's window. You can switch between these grids using the tabs at the bottom of the window.

Adding a second language

To add a new language to the project, click on the + symbol on the Add-In's toolbar

This brings up a dialog very similar to one where we selected the original language of the project.

Select a new language and click on OK to add this language to the project.

Some languages, such as German or French, are considered to be neutral languages. The regional variations, such as German(Germany), German(Austria), French(France) or French(Canada) are referred to as specific languages. You should always add the neutral language before adding a related specific language. If you do choose to add a specific language, the Add-In will give you the option of adding both neutral and specific languages or only the neutral language.

After adding the second language, the Add-In will

• add a new column to the grids for the new language
• search for translations of common texts such as OK and Cancel in the Global Translations Database

Now we will take a closer look at the two grids.

The controls grid

To see the controls grid, make sure that the controls tab at the bottom of the window is selected. The grid should look something like the following screenshot.

By default, the properties are shown in a hierarchical manner, showing the association of properties to controls. As an alternative, you can view the properties on each Form or ))UserControl(( in a flat list. To select this mode, click on the +- button on the toolbar and then select Flat list from the menu, as shown below:

The controls grid will then look something like the following screenshot.

To enter a translation, simply click in cell and type in the new text. If you are able to translate the text yourself, this is the easiest way enter translations.

If a text is shown in light grey, then it is the text which would be retrieved at runtime via the resource fallback mechanism. In general, if a text is not defined for a specific language (e.g. Spanish(Mexico)) then the text for the neutral language (e.g. Spanish) would be used. If this has not been defined, then the original text in the project would be used.

The check boxes to the left of the property name indicates that the text has been selected for translation. By default, all properties which contain a non empty string are selected. In the screenshot above, you can see two menu separators with the text "-". It makes no sense to translate these, so we can remove deselect them by clicking on the check boxes.

In fact, we never really want to see these properties again, so we can go one step further and hide them completely. To do this, we first click on the sun symbol
