Issue Details

I built a front panel application and I want to publish it online. Is it possible to be controlled by different users at the same time?

Solution

The Web Server allows multiple clients to connect simultaneously to the same front panel, but only one client at a time can control the front panel. The user at the server computer can regain control of any VI at any time. When the controller changes a value on the front panel, all client front panels reflect that change. However, client front panels do not reflect all changes. In general, client front panels do not reflect changes made to the display on front panel objects, but rather to the actual values in the front panel objects. For example, if the controller changes the mapping mode or marker spacing of a scale of a chart or if the controller shows and hides a scroll bar for a chart, only the controller front panel reflects these changes.
