I am a newer about LabVIEW.How can I realize a remote control in a Web brower.

Question

"To transform your application into a remote laboratory, make sure the VI that you want to publish is loaded into LabVIEW memory. Next, select the Web Publishing Tool option from the Tools menu. This window is the main window for interactively creating and publishing your remote laboratory
The Web publishing tool will automatically load in the Document Title and VI Name text fields. As the sample image in Figure 6 illustrates, the Document Title, Text 1, and Text 2 are all text fields that you can use to customize the Web page created with the publishing tool.
The second step necessary to enable a remote laboratory is to select the Start Web Server button. When pressed, this button activates the built-in LabVIEW Web server, which will publish and control your front panel images from the Internet.
Once the Web server is activated, the actual HTML document needs to be created and saved so it can be accessed remotely. Clicking on Save to Disk places an HTML file called Document Title.htm into the LabVIEW file folder called WWW by default. Saving your Remote Panels HTML documents into this folder will ensure that the LabVIEW Web server can find them. Either keep the default name, or assign a new name and save the file. Once saved, a new panel entitled Document URL pops up with a message box containing the URL address of your enabled LabVIEW application.
Click on OK in the Document URL window and then click on Done in the Web Publishing Tool window. Your lab is now ready for remote visitors
Required Software
To operate a LabVIEW program using remote panels, it is necessary to have the free LabVIEW run-time engine installed on the client computer. When a remote viewer logs onto the lab with the appropriate URL address, the LabVIEW front panel will appear in the browser, or reroute the user to install the run-time engine from the National Instruments Web site.
Application Control
Once connected to the remote laboratory, the client connection will automatically be in a monitor state. If another client is controlling the remote laboratory, the user will be able to monitor the actions of the controlling client. To request control of the program, right click on the front panel and select Request Control. Once selected, one of two possible messages will appear. Either the user will be granted control (Control Granted), or the user will see a message indicating that control is currently granted to another user (Waiting for control: Either the server is locked or another client has control). If another client has control, the controlling client will be notified that control time has now become limited. Once the timeout occurs or the controlling client has released control, application control is automatically switched to the requesting client (Control Granted). Once the user has been granted control, all icons and controls will become active and running the LabVIEW application is exactly like running the application from the local environment.
Releasing Control
When the remote viewer either moves on to a different URL address or relinquishes control by right clicking and selecting (Release Control), or when the remote laboratory times out, the remote laboratory is available to the next visitor."
The above is what I read from a text of ni.com,
but I can not obtain the result.
Thanks a lot!

Hi
I don't see which LV version you are using. It's important to know, that you need the FDS or PDS package of LV 6.1 to work with remote control. This feature is not supported in the LV base package of LV 6.1.
If you have LV 6.1 FDS or PDS, which of the described steps are not working?
