Custom Actions Editor
Allows you to specify additional actions to be performed on a target computer during installation. Custom actions are contained in .dll, .exe, VBScript, JScript, or Installer class files within your solution.
To access the Custom Actions Editor, on the View menu, point to Editor, and then click Custom Actions when a deployment project is selected in Solution Explorer.
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Visual Studio Settings.
The Custom Actions Editor contains a single pane with a hierarchical list of custom actions. The list is divided into four sections representing the phases of installation.
