WEBDEV - Browser code The files displayed can be:
  • any page, accessible on Internet or on a local network.
  • an Active WEBDEV Page by specifying the value of the parameters expected by the page. These parameters can be retrieved:
    • in the event "Global declarations" of the page.
    • with the PageParameter function.

<Page address>: Character string
URL address of the page that must be displayed in the new browser window. If this parameter corresponds to an empty string (""), a blank page is opened ("about:blank").
If the page to display is an Active WEBDEV Page with parameters, name of the AWP file followed by the parameters to pass to the Active WEBDEV Page. To be directly retrieved in the event "Global declarations" of the page, the parameters must be named P1, P2, .., P256.
<Target>: Optional character string or constant
Name of target frame. <Target> can also take the following values:
CurrentBrowserthe target is the current browser.

This parameter can also correspond to the "_blank" string (compatibility with WEBDEV 1.5).
ParentFramethe target is the container of the current page (parent frameset, parent browser).
This parameter can also correspond to the "_parent" string (compatibility with WEBDEV 1.5).
<Window name>: Optional character string
Name of the new browser window. This parameter allows you to redisplay a page in a browser window with the same name (if several browser windows are opened on the computer of the Web user).
<Options>: Optional Integer constant (or combination of constants)

(Default value)
The window of the new browser will include an address bar and scrollbars (equivalent to the combination of all the previous constants)

Remarks
WEBDEV - Browser codeWindows

Choosing the target of the file

To choose the target of the file, we recommend that you use the <Target> parameter of FileDisplay rather than ChangeTarget. Indeed, in this case, the corresponding JavaScript code is smaller and the size of your pages is optimized.
WEBDEV - Browser codeWindows

Retrieving the parameters passed to an Active WEBDEV Page

Several methods can be used to retrieve the parameters passed to an Active WEBDEV Page:
  1. Retrieving parameters in the event "Global declarations" of the page.
  2. Retrieving the parameters with PageParameter.

Downloading large files

Downloading files with FileDisplay can take longer than downloading files directly via an http link.
When using FileDisplay, the WEBDEV engine:
  1. Opens the file to download.
  2. Transfers the file to the Web server while asking to send the file to the Web user.
When using an http link, the browser of the Web user directly finds the file to download.
For the large files, we recommend that you use an http link. In this case, the path and name of the file to be downloaded can be configured with the URL property.

Pre-launched sessions

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 "Initializing the project after connection to the site" event.
