# Close Application

> `UiPath.Core.Activities.CloseApplication`

`UiPath.Core.Activities.CloseApplication`

Instantly closes the application corresponding to a specified UI element.

If the targeted application generates popups or opens multiple apps/windows, preventing it to be closed in 30 seconds, the
application will be force closed.

Example: Word opens two files in the same PID (process ID). When the **Close Application** activity is run, it will close the first file. The process remains in the memory. After 30 seconds the **Close Application** kills it, closing the second file.

:::note
If you need to close a window within its own application scope, we recommend avoiding the usage of selectors until you are
out of that scope. Closing the window should be the last selector-based activity in the application scope.

## Properties

### **Input**

* **Target.Selector** - Text property used to find a particular UI element when the activity is executed. It is actually an XML fragment specifying
  attributes of the GUI element you are looking for and of some of its parents.
* **Target.TimeoutMS** - Specifies the amount of time (in milliseconds) to wait for the activity to run before the `SelectorNotFoundException` error is thrown. The default value is 30000 milliseconds (30 seconds).
* **Target.WaitForReady** - Before performing the actions, wait for the target to become ready. The following options are available:
  + **None** - Does not wait for anything except the target UI element to exist before executing the action. For example, you can use
    this option if you want to retrieve just text from a web page or click a particular button, without having to wait for all
    UI elements to load. Note that this may have unwanted consequences if the button relies on elements which are not yet loaded,
    such as scripts.
  + **Interactive/Complete** - Waits all of the UI elements in the target app to exist before actually executing the action.
    To assess if an application is in the Interactive or Complete state, the following tags are verified:
  + **Desktop applications** - A `wm_null` message is sent to check the existence of the `<wnd>`, `<ctrl>`, `<java>`, or `<uia>` tags. If they exist, the activity is executed.
  + **Web applications:**
  1. **Internet Explorer** - The `<webctrl>` tag is used to check if the **Ready** state of the HTML document is set to **Complete**. Additionally, the **Busy** state has to be set to "False".
  2. **Others** - The `<webctrl>` tag is used to check if the **Ready** state of the HTML document is **Complete**.
  + **SAP applications** - First the presence of the `<wnd>` tag verified, after which a SAP specific API is used to detect if the session is busy or not.
* **Target.Element** - Use the UiElement variable returned by another activity. This property cannot be used alongside the Selector property.
  This field supports only UiElement variables.
* **Target.ClippingRegion** - Defines the clipping rectangle, in pixels, relative to the UiElement, in the following directions: left, top, right, bottom.
  It supports both positive and negative numbers.

### **Common**

* **DisplayName** - The display name of the activity.
* **ContinueOnError** - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values
  (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the
  project stops. If the value is set to True, the execution of the project continues regardless of any error.
  
  :::note
  If this activity is included in **Try Catch** and the value of the **ContinueOnError** property is True, no error is caught when the project is executed.

### **Misc**

* **Private** - If selected, the values of variables and arguments are no longer logged at Verbose level.
