Setting up the receiving form

The receiving form must be "listening for" messages from the sending form. The receiving form does this by registering for the custom message type specified in the sending form.

To set up the receiving form:

  1. Select a component on the form and then click the “Events” tab on the property sheet.
  2. Create a form event handler, typically for the “StdFormInitCompleted” event.
  3. Click the ellipsis (“...”) button for the “Primary” event field.
  4. In the Event Handlers dialog box, click “New”.
  5. In the “Event Handler Properties” dialog box, specify the name of the event in the “Event” field.
    注意： Assuming you are using a StdFormInitCompleted event, that event name should already be populating the “Event” field.
  6. For the “Response > Type”, select “Send Web Container Messsage”.
  7. Click the ellipsis button for the “Parameters” field.
  8. In the “Event Handler Parms” (Parameters) dialog box, click “Type Specific Parameters”.
  9. In the “Edit Message To Web Container” dialog box, from the “Message Type” drop-down list, select “registerMessageHandler”.
  10. In the “JSON Message” field, specify the name of the custom message type that you created in Step 9 of the previous section.

    This step allows the receiving form to monitor for “StdWebContainerMessageReceived” events being generated by the sending form.
