# Use Foreground

> `UiPath.Core.Activities.UseForegroundScope`

`UiPath.Core.Activities.UseForegroundScope`

Moves the current background process into the foreground, executing all the activities it
contains. After the execution is complete, the process is moved back into the
background.

## Properties

### **Common**

* **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.
  :::
* **DisplayName** - The display
  name of the activity.
* **Wait for foreground** - The
  maximum amount of time the process should wait in order to move into the
  foreground. If left empty, it will wait for an infinite amount of time. If the
  process does not move into the foreground in the specified amount of time, an
  `InvalidOperationException` error is thrown. By default, this
  field is empty.

### **Misc**

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

## In UiPath Assistant

When a
process is running in the background it displays the background icon in **UiPath
Assistant**. When it acquires the foreground, the background icon
disappears.

## Queue Mechanism

If you
start a background process with a foreground scope and another entity is running in
the foreground (either a process or another foreground scope), the background
process goes into a queue and waits (determined by the **Wait for foreground**
property) to acquire foreground.

There is no limit to the items in this
queue.

Only background processes with a foreground scope make use of this
queue, not standalone foreground processes. This means that a foreground process
fails if started while you are running either another foreground process or a
background process with a foreground scope.

Background processes that are
waiting in the queue to acquire foreground display an hourglass icon.
