PROCEDURE <Page name> (<Parameter 1> [, ...[, <Parameter N>]]])

Multilingual websites

<Page>.Use can be used in multilingual sites. This function is used to reopen a page while taking into account the language specified by Nation.

Principle for opening a page

<Page>.Use does the following:

close all the opened context on the server
create a page context on the server
returning the page to the browser of web user.

Note: If <Page>.Use is used in the code of a Button control, the page will be opened in the target defined for this Button control ("General" tab of the control description or ChangeTarget).

Events and codes run when <Page>.Use is called

The following events are run when the page is displayed:

Page opening code ( "Global declarations" event of the page).
"Initialization" event of the page controls.
Display page in the browser.
JavaScript code associated with the page and the controls.
WLanguage code after the call to <Page>.Use (if used).

Opening a page of an external component

To open a page of an external component, use the name of the page of the external component (the component being included in the project). For example:

ComponentPage.Use()

If a conflict occurs with a project element, the name of the element must be prefixed by the name of the external component. For example:

MyComponent.Page.Use()

To use the name of the page in a variable, the name of the external component must be specified. For example:

sPage is string = "MyComponent.MyPage"

sPage.Use()

Miscellaneous

To redisplay a page, it is recommended to use <Page>.Refresh.
To display a page without closing the contexts opened on the server, we recommend that you use <Page>.Display.
You should not use WLanguage code after a call to <Page>.Use.
If your project uses pre-launched sessions, this function must not be used in the project initialization event. This function must be used in the "Initialization in pre-launched session mode" event.
