What Are the Limitations of the LabVIEW Remote Front Panels?



Primary Software:
Primary Software Version: 8.5.1
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I am considering the use of remote front panels to make my application available over a network. Are there any limitations I should be aware of?

Solution:
For LabVIEW 7.1 or earlier, refer to the LabVIEW User Manual (linked below) for information about remote front panels. For LabVIEW 8.0 or later, refer to the Viewing and Controlling Front Panels Remotely topic in the LabVIEW Help (linked below). The following list contains some limitations you should keep in mind:
  • Property nodes that manipulate the location and dimensions of the front panel my not work properly.
  • Avoid while loops with no wait functions
  • ActiveX controls embedded on a front panel do not display on a remote client.
  • You cannot use the standard file dialog box.
  • The file path browse button is disabled.
  • 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 more information, see KnowledgeBase 3K7COT23: Remote Front Panel Image Does Not Reflect Property Node Changes that Occur Prior to Connection.
  • If there are any VI's dynamically called with VI server or subVIs configured to display their front panel, only one client can see those front panels. This client is the one who has control of the VI.
  • Polling properties of a front panel control might experience decreases in performance.
