• Javascript - You can include it using a <script> tag, which injects the flair into the DOM via Javascript.
  

  <script
    src="http://www.mangst.com/flair/javaranch?id=209694&type=js"
    type="text/javascript">
  </script>
  

• HTML - You can include it using an <iframe>, which loads the flair as HTML into the frame.

• Friendly name - This can be anything, but should be the name that's on the HealthVault record.


• Question - A question of the user's choosing (such as "What high school did I go to?").


• Answer - The answer to the above question.

//create the request
CreateConnectRequestRequest request = new CreateConnectRequestRequest();
request.setExternalId(System.currentTimeMillis() + "");
request.setQuestion("Question?");
request.setAnswer("Answer");
request.setFriendlyName("Joe Smith");

//send the request / get the response
SimpleRequestTemplate srt = new SimpleRequestTemplate(ConnectionFactory.getConnection());
CreateConnectRequestResponse response = (CreateConnectRequestResponse) srt.makeRequest(request);
String identityCode = response.getIdentityCode();

Note:

Because we're using the JAX-B request classes, be sure to use com.microsoft.hsg.methods.jaxb.SimpleRequestTemplate and not com.microsoft.hsg.request.SimpleRequestTemplate

Note:

The CreateConnectRequest method has a "call-back-url" parameter, which is a URL that HealthVault is supposed to call when the connect-request is validated by the user. However, at the time of this writing, it is not supported.

1. Create a shortcut on your desktop to the Netbeans executable: C:\Program Files\NetBeans x.x\bin\netbeans.exe.


2. Right-click on the shortcut and click "Properties".


3. In the "Target" textbox, add the extra parameter to the very end:
   
   --userdir C:\path\to\new_workspace


4. Click "OK" to exit the Properties window and double click the shortcut. Netbeans will launch and create/load the workspace at that location.
