Open(TargetAppModel, TargetAppOptions)Ouvre une application de bureau ou une page Web spécifique à utiliser dans UI Automation, identifiée par l'objet TargetAppModel .
Open(String, String, String, NAppOpenMode, NWindowResize, NInteractionMode)Ouvre une application de bureau ou une page Web spécifique à utiliser dans UI Automation, identifiée par le nom d'écran du référentiel d'objets, ainsi que d'autres personnalisations de l'application ou de la page Web.

Open(String, TargetAppOptions, String, String)

Ouvre une application de bureau ou une page Web spécifique à utiliser dans UI Automation, identifiée par le nom d'écran du référentiel d'objets.

    string screenName,  
    TargetAppOptions targetAppOptions, 
    [string appName],
    [string appVersion])
Open(
    string screenName,  
    TargetAppOptions targetAppOptions, 
    [string appName],
    [string appVersion])

screeName String : le nom de l'écran sur lequel vous souhaitez vous concentrer, sous la forme d'une String enregistrée dans le Référentiel d'objets.

targetAppOptions : options et paramètres supplémentaires pour se connecter à l'application ou à la page Web :

* `Timeout Double` - Specify a number
  of seconds for which to wait for the activity to be executed before
  throwing an error. The default value is 30 seconds. When indicating
  a window in a Remote Desktop environment, the Timeout default
  setting is set to 60 seconds.
* `InteractionMode
  NInteractionMode`:
  + `HardwareEvents` - Uses the hardware
    driver to perform the action. This is the slowest API, it
    cannot work in the background, but it is compatible with all
    desktop apps.
  + `Simulate` - Simulates the action using
    accessibility APIs. Recommended in browser automation, Java
    apps, or SAP. More reliable than Hardware Events. Sends all
    text in a single action. Works even if the target
    application is not in focus. Please test if your target
    application UI element supports this.
  + `DebuggerApi` - Performs actions using
    debugger APIs. Works only for Chromium elements. Sends all
    text in one go. Works even if target app is not in focus.
    For more details, check out this [page](https://docs.uipath.com/studio/docs/chromium-api).
  + `WindowMessages` - Sends the mouse and
    keyboard input through Win32 messages. Recommended for
    desktop apps. Usually more reliable than Hardware Events.
    Sends all text in a single action. Works even if target app
    is not in focus. Please test if your target application UI
    element supports this.
  + `Background` - Runs actions in the
    background. Tries to use either Simulate or Chromium API
    where possible, while complex APIs (image, native text)
    run as usual, in the foreground. It is highly recommended to
    use this API with the [Verify Execution](https://docs.uipath.com/activities/other/latest/user-guide/project-settings-ui-automation)
    feature.
* `OpenMode NAppOpenMode` - choose when
  to open the app:
  + `Never` (never open the
    application)
  + `IfNotOpen` (open only if the
    application is closed, this is the default selection, only
    works if `FilePath` or `URL`
    are provided)
  + `Always` (open another instance of the
    application even if one is already open, only works if
    `FilePath` or `URL` are
    provided)
* `WindowResize NWindowResize` - choose
  the size of the window:
  + `None`
  + `Maximize`
  + `Restore`
  + `Minimize`
* `UserDataFolderMode
  BrowserUserDataFolderMode` - The
  `UserDataFolderMode` you want to set. It is used
  to start the browser with a specific user data folder.
  + `Automatic` - Picture In Picture mode
    uses a different folder than the default mode, automatically
    generated if `UserDataFolderPath` is not
    set.
  + `DefaultFolder` - Uses the default
    browser folder, no matter if it runs in the main or PIP
    session.
  + `CustomFolder` - Uses the folder
    specified in `UserDataFolderPath` or an auto
    generated path if `UserDataFolderPath` is not
    set.
* `UserDataFolderPath String` - The
  user data folder that the browser uses. Defaults to
  `%LocalAppData%\UiPath\PIP Browser
  Profiles\BrowserType` if not set.
* `IsIncognito Boolean` - input
  `True` if you want to open the browser in
  incognito mode. By default it's set to `False`.
* `WebDriverMode NWebDriverMode` -
  Indicates how the WebDriver is used when opening a new browser
  session. The following options are available:
  + `Disabled` - Disables the use of
    WebDriver.
  + `WithGUI` - The GUI of the browser is
    displayed.
  + `Headless` - The browser is launched
    silently, with no GUI.
* `Timeout Double` - Specify a number
  of seconds for which to wait for the activity to be executed before
  throwing an error. The default value is 30 seconds. When indicating
  a window in a Remote Desktop environment, the Timeout default
  setting is set to 60 seconds.
* `InteractionMode
  NInteractionMode`:

Exécution de WebDriverMode sans affichage

Pour utiliser WebDriverMode dans une configuration sans affichage, ces étapes peuvent servir de guide.

Commencez par définir une variable pour votre écran. Utilisez la fonction uiAutomation.Open pour ouvrir une nouvelle application dans le navigateur de votre choix (Edge dans cette instance). Puis, utilisez la classe Options dans la surcharge pour spécifier certaines options de navigateur. Parmi ces options, définissez webDriverMode sur NWebDriverMode.Headless.

Le code correspondant ressemble à ce qui suit :

var screen = uiAutomation.Open(Descriptors.NewApplication.Edge, Options.AppOpen().WithBrowserOptions(webDriverMode: NWebDriverMode.Headless));
var screen = uiAutomation.Open(Descriptors.NewApplication.Edge, Options.AppOpen().WithBrowserOptions(webDriverMode: NWebDriverMode.Headless));

Ce code définit WebDriver en mode sans affichage, permettant l’automatisation du navigateur sans que le navigateur soit visiblement ouvert.
