Disabling native ring drop-down

Does anyone know how to disable the native drop-down list of controls of the ring and enum. I work (disabled) when I use the event filter and throw the mouse down event. I pop up my own fall down in a sub VI in this event and it works perfectly. However, when I try to get mouse support for this control via an event loop control, I can't throw the mouse down event because it seems to ignore all the events that are configured for this. I if a timer in case case would give me enough time to receive the event into the loop of surveillance, but unfortunately not good it (never fires). Maybe I should describe a little better:

I have two event nodes that are put in place to trigger on a mouse down event. The first is filtered to remove from the drop-down list the current LabVIEW. The second loop is top sink my code for my own downfall. This works perfectly for each type of control, I want to (string, digital) except when labVIEW runs special background code for the menu drop down. Why LabVIEW destroyed the mouse down to all the nodes in the event if only one is filtered. I can use the mouse event and it works perfectly, even if I need the mouse down to the additional functionality, I already coded and works. I have a way around this, but I WANT it to work that way for various reasons. I want no additional code in case of loop as a queue or messaging to build to handle this. It would defeat the purpose of my experience (of which I'm sorry I can't be more explicit in the details).

Why must my code be found in the events node in order to make it work? If there are two nodes of events registered for the same event, they both should receive them without worrying if one removes it by filtering. right?

Thanks in advance

A dark place in the LabVIEW help file:

To filter events, LabVIEW send event sequentially to each structure set up for the event event. The order in which LabVIEW sends the event filter to each structure of the event depends on the order in which you record events. Each structure the event must rule on the case of event before filter LabVIEW can prevent the next structure of the event. If a case of structure of event changes the event data, LabVIEW passes the data changed to structures of later event in the chain. If emissions of a structure of the event in the chain of the event, LabVIEW does not pass the event of any structure of event remaining in the chain. LabVIEW complete the user action that triggered the event configured only after any event structures treatment handle event without throwing.

For example, you run the vi with the filtering event loop before running that the vi with the event no filter, the filter event loop would first register (register of events using a vi containing the static events).   Changing the code to save the two events as events filtering and without mods on the first lap of the event should allow you to act first and then filter then.

    Disable search suggestions by right clicking the text field in the search bar and remove the mark in front of "Show Suggestions".

    Click the search engine button and open "manage search engines".

    At the bottom of this window, there is a box of [X] "see search suggestions."

  • The drop down menus work intermittently; all add-ons are disabled.

    When I run the cursor over a menu item; File, Edit, history, etc., the drop down menu does not decrease. If I click on the menus, drop down menus will appear and then disappear. If I continue to do this for several seconds, the menu will be displayed when selected. I'm having the same problem with this help screen when I do a right-click with the mouse.

    I modified the example found here - http://digital.ni.com/public.nsf/allkb/0CC5602FE23E86DA86257350004E1B6A. You will have to manipulate the position of the mouse to navigate to a specific line, but this will open the ring.

  • How to disable the outdated information bar drop-down notice?

    From Firefox makes annoying drop-down view ' your Firefox is obsolete. " Updated now for better performance and security. "No S * Sherlock and the reason is this dev team ruined the browser little by little over the last five years so I stopped editing after that groups of tabs have been removed and the oh so familiar 'use an add-on' answer has been given.

    Both: configuration value to disable this notice is all I need?

    Ease of use first, and then security.

    My prefs.js was missing these: app.update.enabled - app.update.silent false - false

    I tried to add them earlier, but Firefox has been accidentally running while I was editing the prefs.js so he crushed.

    I think it did the trick. user_pref ("app.update.auto", false); user_pref ("app.update.enabled", false);

    Thanks for the help. (always disagreed with the harsh dev choises)

    PS: I think I'll just start by prefs.js clear if the problem reappears.
