Initialize Method (Module)

In This Topic

When overridden in a derived class, gives the custom Module a chance to initialize itself and return its status to the calling Framework.

Syntax

C#
Visual Basic (Declaration)

protected internal virtual bool Initialize()

Protected Friend Overridable Function Initialize() As Boolean

Remarks

A custom Module has two opportunities to initialize itself: its class constructor and its Initialize method. The Framework calls both functions whenever a Module is loaded. Modules load either explicitly with FrameworkApplication.FindModule or implicitly whenever any of their DAML elements (Panes, DockPanes, Controls, etc) are loaded. For example, when a DockPane or a Button on a Ribbon Tab is created, their parent module will automatically load if it hasn't already done so.

The Initialize method has the added benefit of returning whether the initialization was successful or not. If initialization fails, the Framework immediately calls Uninitialize.

Example

How to determine when a project is opened

protected override bool Initialize() //Called when the Module is initialized.
{
  ProjectOpenedEvent.Subscribe(OnProjectOpened); //subscribe to Project opened event
  return base.Initialize();
}

private void OnProjectOpened(ProjectEventArgs obj) //Project Opened event handler
{
  MessageBox.Show($"{Project.Current} has opened"); //show your message box
}

protected override void Uninitialize() //unsubscribe to the project opened event
{
  ProjectOpenedEvent.Unsubscribe(OnProjectOpened); //unsubscribe
  return;
}
