Detecting mouse activity on PC in labview

I tried the Serial loopback test vI and the serial to disk VI, but both the VIs failed to detect any activity at the serial port of my PC. Also, The VISA interactive driver was not able to detect the serial port. It gave an error saying the device is detected but VISA is unable to access it, what does that mean? What is the best way to detect and control the com port of my PC

You will get this error if you have another application open that is accessing the serial port. If you have a terminal emulation program running such as Hyperaccess, close it and try VISA again.

How do I turn off background ni file activity when not using Labview? files such as nimxs.exe, nipalsm.exe, nipalsm.exe, nisvcloc.exe, nicitdl5.exe

How do I turn off background ni file activity when not using Labview? I use labview rarely, and I also use my computer for demanding multimedia applications, including multitrack digital audio recording. I need to reduce as much background activity as possible, and taking a look with task manager I see files such as nimxs.exe, nipalsm.exe, nipalsm.exe, nisvcloc.exe, and nicitdl5.exe running even when I haven't used Labview (8 I believe). These files run even after I right click the NI icon on the lower right and turn off the application. I would like the computer to boot up without these files, and for the necessary files to be activated only when I start the program.
Can this be done or do I have to remove labview from the system to improve performance?
Thanks

Hello, those processes are part of running NI services that start when Windows boots. These processes serve varied purposes and stopping them can have undefined and unknown consiquences for your NI products. These products run at "normal" priority meaning that they should be preempted by any process running at a higher priority which I would expect your other application to be doing given their time sensitivity. That being said, in Windows XP (I can't speak for other OSes), you can lower their priorities even greater through task manager (right click the process»set priority) to further remove them from contention for resources. If you want to prevent them from running you can set the service startup type to "manual" in Control Panel»Administrative Tools»Services. Right click the process go to Properties and Under the General tab choose Startup Type»Manual. This will start up the processes only when something directly starts it up. LabVIEW will start these processes up as it attempts to use them. When you shut down LabVIEW you will need to manually shut down these processes through task manager. Again, doing this can cause problems with your NI products on your system and it is not advised.

Possible to have mouse activated slider with buttons for selection

Hi,
I was wondering if anyone has/is or if this can be dome easy enough....
For example, instead of placing a row of buttons on the bottom of the template, instead, is it possibloe to have a mouse activated slider that the buttons are on and is activated when the mouse hovers over it.....?
Hope that explanation is clear enough...;-)
Cheers

Captivate 7 has an option to show playbar on hover. It becomes available when you select Overlay Playbar. But this only applies to the standard skins that come with Captivate. It won't help your specific need to have a set of buttons appear on hover over a hit area.
It should be possible to do what you want. But you'll need to group the buttons, give the group a name, create separate advanced actions that apply a fly-in and fly out effect to the group, then execute these actions via an event. In your case you want the event to occur as a result of a rollover and rollout on a hit area.
Captivate's slidelet object has a rollover event, but no rollout event you can use.
The only way I know to have both rollover and rollout events is to use the Infosemantics Event Handler widget:

Detect mouse down or click outside

Hello,
I'm trying to detect Mouse Down or Click event outside of a TextInput element.
This doesn't work:
myInput.addEventListener(FlexMouseEvent.MOUSE_DOWN_OUTSIDE,aHorseWalksIntoABarAndTheBarten derAsksHeyWhyTheLongFace);

Hm... It's a custom TextInput component, I need to listen to this from inside it.
How does DateField or DropDownList do this? They close the DateChooser and List when clicking outside.
I saw something to do with mx_internal, but I'm not sure if I should be using that.

Detecting mouse clicks in editable cell of JTable

Hi everyone :)
I thought that this question might have been asked before, but I have searched the forums extensively and have not been able to find the solution.
What I want to achieve is to detect single and double mouse clicks on JTable cells (that are editable).
For example, I have a JTable and there exists within it an editable cell. If the user clicks on it once then that cell goes into edit mode, and the user can type directly into the cell. I have already successfully implemented this.
However, what I also want to do is detect a double-click so that I can pop up a dilaog that shows a list of default values that the user can select.
So here is what I want;
1. User clicks on the cell once.
2. Cell moves into edit mode.
3. If the user clicks again within a certain time interval then cancel edit mode and pop up a dialog containing values that the user can select from.
I think that to do this I need to be able to detect mouse clicks on the cell that is currently being edited. So far I have been unable to discover how this is done. I have even tried extending JTextField to get what I want, but with no luck.
Any help would be greatly appreciated.
Kind regards,
Ben Deany

Thanks for the reply.
Unfortunately, it is not possible to call 'AddMouseListener()' on a cell editor. You are only able to call 'addCellEditorListener()' and that only allows two events to the broadcast (edit cancel, and edit stop).

WRT54GS cannot detect an active internet connection. HELP!

Ok well just recently, I don't know why though but my router won't detect an active internet connection from my Cable Modem. I have my Router and Modem connected so I can play Xbox in my room. Well since my router can't detect an active internet connection now since the new Xbox update doesn't allow you to enter the encryption key anymore, I can't go on Xbox live because of it. I've tried changing the ethernet cable in different ports and it still doesn't work. If someone can please help me with this, it would be greatly appreciated. Thanks.
Solved!
Go to Solution.

You should reset your router and re-configure it...
1. Press and hold the reset button for 30 seconds.
2. Then, unplug the power keep holding down the reset button for
another 30 Seconds.
3. Plug back the power back in, and keep holding down the reset button
for 30 Seconds.
4. Release the reset button.
To re-configure your router follow this

How to detect mouse clicks on desktop?

Hi All,
I need to detect mouse clicks on the desktop and find out mouse position on the screen. How to listen to mouse events if I don't have any swing components like containers, panels, windows, etc? All things like "addMouseListener" are supposed to be with such components. But my program is running in the background and it doesn't have any graphical interfaces. So, I need to detect if a mouse button is pressed at any position on the screen.
Thanks for any help!

Why? What program feature do you intend to offer, by knowing what a user clicks on (besides the application itself).Hi, well what I have to do is to start the application minimized in the system tray. Then the application must be listening for crtl+shift+left click in any part of the desktop or an opened application, when that happens, I have to show a window asking if the user want to take a screenshot starting in the x,y point he clicked, once done, I have to take an screenshot...so on.
How can I do that? Can anybody give me a hint? Thanks in advance.

Upgrading to R2 stuck on "Configuration Manager has detected an active MP Replica on this site."

Hello Everyone,
We are installing upgrading our SCCM 2012 server to R2 and we are stuck on;
"Configuration Manager has detected an active MP Replica on this site. Please deactivate this MP before continuing upgrade."
I have tried disabling SQL service on the MPs but that didn't work. So could anyone give me any help on the procedure on how to deactivate the MP as requested?
Thank you in advance for anyhelp.

From the beginning we didn't have Replicas at all!
We checked each DP and Secondary Site and they are already all disabled.
You should have mentioned that fact earlier ....
What did you check and what's disabled?

How to detect mouse movement/key press on Mac?

Need to write a VI that will detect/report mouse movement (ie. returns it's location) and any key (or key combinations) pressed. And, to send the mouse pointer to any location on screen. Using Labview 6i on Mac.

The event structure is new to LabVIEW 6.1. I could post 6.1 code but I cannot save the structure for previous and LabVIEW will not open a VI from a newer version. The best place to learn about the event structure is on the What's new in LabVIEW 6.1 page.

Detecting application activation in taskbar

Hi,
I am positing in this forum after receiving no response in the swing forum.
I currently have a swing application to which I want to add "detect file updated by external program" functionality. I already have the code that does this but I have currently added it to the internalFrameActivated method. But I want to popup the message automatically when the user activates the application from the taskbar. The way it works now is after activating, the user has to click on one of the open internalframes to select it at which point the message pops up.
Addind it to WindowActivated causes the message to popup on every key press or mouse movement. I only want it to popup once. Can somebody tell me how this can be achieved.
Any help is appreciated.
Cheers,
Omprakash.V

Yes, if you write this in the Constructor block.
However, I can not setResized my jframe.
public jframe()
super("Title Test");
this.setUndecorated(true);
this.setResizable(true);
initComponents();
I don't think that both of them can co-exist together.What is your opinion? I am looking around for another classes.I will let you know if I found something...

How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

Flash video performance poor in Firefox 3 and other newer Gecko-based browsers; fails to detect mouse movement in full-s

Regardless of configuration, I have found Flash video
performance on Firefox 3 to be severely sub-par. Numerous visual
lags occur throughout a typical Youtube video as it cannot seem to
manage to maintain a steady frame rate. When in full-screen, mouse
movement is not detected, forcing me to click in a full-screen
Vimeo video in order to display its controls when I should have
only needed to move the mouse. I was informed that the technical
explanation for this is that Flash isn't triggering MouseEvents
other than MouseEVENT.CLICK.
In my tests, this behavior also occurred in Flashplayers 9
and 10 as well as with recent versions of other browsers that also
use the Gecko rendering engine, namely Camino, Flock and Songbird,
but not in Firefox 2. I was told by a Mozilla employee that this
issue can only be solved by Adobe.
This has forced me to use the Safari browser as my only
available work-around. I implore that these issues get resolved as
quickly as possible.

guys, im exactly experience the same issue here.. any
solution guys? tks in advantage..

Satellite P205 - mouse activation of FN display

I am using a Satellite P205 with Vista OS. The Toshiba FN functions are displayed by either pressing the FN key or moving the mouse over the top of the display screen. It is the mouse over activation that bothers me.
Often enough, in general use, my mouse will enter the area that triggers the display and if I use the left mouse button the associated function is activated. If I am working quickly this will happen unintentionally. I am finding this increasingly annoying and would like to disable the mouse over activation. If I want to use the FN option, I want to do so with the FN key.
Does anyone know how to disable the mouse over display?

To be honest I am wondering you ask this. I know, it sounds now stupid but I will tell you why.
If you don't like some function it is logic to check all available options for something.
So if you open Settings for Flash Cards you will find one option there *Allow the mouse to bring up the cards.*
Just remove the check mark for this option and the Flash Cards will be shown when you use FN key only.
Bye and if you have more questions you are welcome. ;)
