# On Activate Document

> On Activate Document runs before a document opens in the FlexiCapture editor; set the CanOpen parameter to false in your script to block opening.

## When it is launched

The script is launched prior to activating the document in the task window (by a double-click, by using menu commands, etc.).

* If the **CanOpen.Value** property is set to **true**, the document will be opened in the document editor after the script execution.
* If the **CanOpen.Value** property is set to **false**, the document will not be opened.

By default, the value of the **CanOpen** parameter is **true**.
