web publishing tool

[Huynh]

Hi everybody,

there's a question I have about the Web Publishing Tool. We are on LabView 8.5. I have tested the Web Publishing Tool a little bit. Now I have found out that only one client can control the VI. Is there a possibility you can make an LabView application available for more clients working synchronous with the application? Do I have these possibilities with the Internet Toolkit? The application shall run as an server application, so that any client can control the application at the same time.

Hope somebody can help me out.

Thanks in advance!

Kind regards,

Lu Huynh

Hey Huynh,

Using the web interface it is not possible to perform this because, as you wrote, only one client is able to control the VI. However, you can close the connection to the controlling client after a fix amount of time, so another client can take control.

Another way would be to use multiclient TCP/IP communication (please look for examples with the example finder within the LabVIEW help menu), where you have to build an executable for every client to only need the runtime engine installed for controlling your application. Or you can use shared variables instead of TCP/IP for the communciation.

Hope this helps, Christian

Hi Christian,

thanks for your reply. So even the Internet Toolkit doesn't help to solve the problem? I'm gonna check what you mentioned. Otherwise our developers have to be satisfied with the option that only one client can use the VI's / application. Thanks a lot.

Kind Regards,
