The following list includes functionality not supported and recommendations to consider when viewing and controlling remote front panels.

• Because of the constraints of a Web browser, user interface applications that attempt to manipulate the dimensions and location of a front panel do not work properly when that front panel is displayed as a part of a Web page. Although the Web Server and the LabVIEW browser plug-in attempt to preserve the fidelity of complex user interface applications—in particular, those that present dialog boxes and subVI windows—some applications might not work properly in the context of a Web browser. National Instruments recommends that you do not export these types of applications for use in a Web browser.
• Avoid exporting VIs that have While Loops but no wait function. These VIs prevent background tasks from performing in a reasonable amount of time, making front panels unresponsive when viewed or controlled remotely.
• Some VIs might not work exactly the same way from a remote computer as they do when run locally. .NET and ActiveX controls embedded on a front panel do not display on a remote client because they draw and operate almost completely independently of LabVIEW. If a VI presents the standard file dialog box, the controller receives an error because you cannot browse a file system remotely. Also, the browse button of a path control is disabled in remote panels.
• Clients viewing a front panel remotely might see different behavior depending on whether the front panel they are connecting to is from a built application. Specifically, if the front panel is from a built application, any programmatic changes to the front panel made before the client connects to the front panel are not reflected on the client computer. For example, if a Property Node changes a caption on a control before a client connects to that front panel, the client will see the original caption of the control, not the changed caption.
• Only a controller can remotely view the front panel of a VI dynamically opened and run using the VI Server or the front panel of a subVI configured to display the front panel when called. Clients not controlling the VI cannot view the front panel.
• Block diagrams that achieve certain user interface effects by polling properties of a front panel control might experience decreases in performance when you control the VI from a remote computer. You can improve the performance of these VIs by using the Wait for Front Panel Activity function.
• LabVIEW cannot generate a Panel Close event for a VI being viewed or controlled remotely. If you are viewing or controlling a VI remotely, LabVIEW can generate events only in the Control class, that is not in the Application or VI class.
