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

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

The following events and codes are run when the page is desplayed:

Page opening code ( "Global declarations" event of the page).
"Initializing" event of the page controls.
Display page in the browser.
Javascript code associated with the page and the controls.
WLanguage code following the call to <Page>.Use (if it exists).

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 re-display a page, we recommend that you 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.
