Publish element

To trigger an event, nest a Publish element inside a Control element. For example, to cause a PushButton control to open a new modal window, add a Publish element inside it that specifies the SpawnDialog event with its Event attribute, as in the following snippet:

<Control Id="ShowPopupButton"
         Type="PushButton"
         Text="Show Popup"
         Height="17"
         Width="56"
         X="245"
         Y="243"
         Default="yes">
  <Publish Event="SpawnDialog"
           Value="PopupDlg">1</Publish>
</Control>

You'll find that different events require different arguments in the Value attribute. Here, Value takes the Id of the Dialog element you want to open. Also, notice that we've used a conditional statement as the inner text of the Publish element. Setting it to 1 means that it will always be true and always trigger the event. However, you can also test that a property, perhaps set by another control event or a custom action, evaluates...
