• Is it possible to block the execution of Javascript from an IP address?

  In accordance with article http://tech.firstpost.com/news-analysis/more-trouble-for-airtel-injects-javascript-code-to-monitor-data-usage-activist-receives-notice-270111.html, my broadband provider is inserting javascript in web pages browsed by me. I would like to block the download and execution of Javascript to this IP address. is it possible to do?

  Have you tried the YesScript extension? It can block scripts by IP (or domain name).

  1. Add YesScript in Firefox.
  2 Add-ons Manager open (Ctrl + Shift + A)
  3. click on Extensions
  4. click the button Options of YesScript

• Blocks the execution of the user Image Acquisition interface

  I am currently trying to create a user interface that displays images from a camera attached to a microscope with a mobile table.  The user is able to interact with the images and can click on them, which causes the table to move to a new location.  Acquisition is made by calling a DLL, the DLL grey flycapture point camera, using a call library function node.

  When I acquire images at 15 frames per second, it has no problem with user input.  However, when I drop the acquisition at 2 frames / second (necessary if you need to have the exposure time), labview seems to take a break from the user interface while the image acquisition is underway.  Interaction of the UI seems possible in the holes between the image acquisitions.

  I'm sure that this is happening because there is a kind of blocking going on here.  The program is waiting for the new image to be returned and will not not something else happen while he waits.  I have image acquisition running in a separate, called function from a higher level, VI, which puts the image data in a global variable (I know I know... global variables).  When I need to display the image, I read of the global variable and display it on my form of user interface.

  I think I need to run things in separate threads to avoid the problems that I have because I have a dependency that is the cause of blocking.  I'm looking for any suggestions on how I can the architect this.  I have thought about using a VI server to launch the acquisition of the camera and will try to implement this, but I wonder if there is another method that I'm missing here.

  Any suggestions would be greatly appreciated!  I use LabVIEW 8.6 on a Windows 7 machine indeed.  I do not use LabVIEW image acquisition module.

  Thank you

  Hey Gerry,.

  It's Paul in Ministry here at National Instruments engineering applications. What Paul was referring to a call library function node configuration properties. If you right-click on the node library function call you can click on configure and you should see a window that looks like the image below.

  

  As you can see, you have the option to select run this library in the UI thread or any thread. This is important because there is only a single user interface thread. Therefore, deadlocks can occur when the code is written in parallel, but operations are both occurring in the UI thread. What results is a part of the code has to wait that the other part at the end and so the lock upwards in the user interface. The reason why the call library function node is set to run in the default UI thread is now, because only the security thread functions can be performed in any thread. So before you change this configuration it is strongly recommended that you check that the functions you call are thread-safe. You can also check which configuration, the node library function call is in the color of the node itself. If it is an orange color which means that it is set to run in the UI thread. If it is a pale yellow color, it is set to run in any thread. Let me know if you have any other questions!

• Click and hold the windows bar blocks the execution of LV

  Hi guys

  I have a real time data acquisition application which usually is runnning full screen, and as such, I have encountered this problem before, but now we have moved to a scalable scheme and it becomes a problem...

  When you click on and hold the bar title of a VI running windows, LabVIEW hold completely running the application for a second round... To be more specific: If you just click on it and move the window instantly is not a problem, but if you click and hold the left button on the title bar of the windows of the VI / .exe running, execution stops for nearly a second.

  For acquisition of data in real time, it's quite a long time to strangle the reading process.

  I tried this on two different brands of PC and I can reproduce at the same time.

  Does anyone know what causes this behavior and, eventually, how to work around it... VI has been tested on XP and LV 8.6.1

  PNG joined something 'very complex' code to illustrate the problem

  

  Thanks in advance.

  This question has been asked before, and Lynn provided the same advice that I was about to suggest - create a separate UI than the DAQ VI VI so that they function as 'independent' (I use that Word loosely) process. The DAQ VI acts as a loop of producer supplying the consumer UI VI, where the 'buffer' that is allowed to fill in between is a queue, not the buffer very limited hardware.

  Sorry to break the news, but if you want to solve this problem, probably as the only solution is to have several VI for your two processes. (By the way, I am able to confirm the delay of 500-600msec when clicking on the title bar in Windows 7 Windows uses a very recent version of LabVIEW)

• GUI - how to block the execution of the parent event handler

  Hello

  IM learning flex, I did my first http://www.narutogis.appspot.com/ app and have some problems with the events of the controls.

  my application is composed of canvas (as a parent) + 4 buttons + image (svg) and now:

  • When I click on one of the 4 buttons as their 'click on' events are triggered, but after that it also runs 'click' event of the canvas parent. I don't want this feature can I block sort of parent controls event handlers. SImple click on the button must execute only the button ' click on ' event, nothing more
  • When I click on the image it won't run "click event" canvas parent (reverse situation to that at the top) by clicking on the Image cntrol must execute the 'click' event Image and also parent canvas 'click' event
    

  You probably need stopImmediatePropagation()

• Use blocks vision acquisition GUI

  I am creating a VI that acquires images when the user presses a button 'OK '.
  and stops when the user presses the button "STOP".

  I created a structure for the event that fires on a change in the value of the GO button.  Inside this structure of the event, I put in a "while loop" that repeatedly calls 'Vision acquisition VI' to acquire and display an image, and it works fine.  The 'while' loop is set to end at the time when the user clicks on the button "Stop".

  The only problem is that the acquisition of Vision apparently blocks the execution of the GUI, so the 'Stop' button does not respond to clicks.  I can press the 'Stop' button and force the VI all quit smoking, but I want to be able to keep the CITY running and stop the loop.

  Any thoughts?

  Thank you

  Steve

  Of course, as soon as I post the question I find the solution.

  The solution is to right-click on the window of the case and choose 'Edit events managed by this case. "

  On this Panel, at the bottom, there is a checkbox indicating "front lock panel until the end of the event" or something similar.   Uncheck the box.

  Best,

• Windows 7 has blocked a file that I am trying to unzip

  Windows 7 has blocked a file I'm trying to decompress. Well I downloaded, but when I am trying to extract all of the files, he said
  Windows has found potentially dangerous program. Windows security has blocked access to this file. What is the problem and how to fix it.

  Hello

  Welcome to the community of Microsoft and thanks for posting the question. I've surely you will help find a solution on the issue.

  If Windows 7 inform you that this file is harmful then you can safely assume that it is. It was probably altered during the compression process. Try to get an intact copy.

  If you think the file is absolutely safe, I suggest to view the steps described in the article and try to perform.

• Declare the cursor within the begin/end block

  Hi all
  Can we declare a cursor inside a begin/end block. If we can, please let me know how. I want to declare a cursor where it will return value based on the settings of the user. User will enter in as username(for example), we have to recover the ID, the user name and we must move to cursor. To do this, we wrote a query to fetch id in a variable in the other block of start/end and we pass this variable in the cursor. Is this possible.
  
  
  
  Thank you and best regards,
  Mahesh

  In general, yes you can, you simply nest another block of execution inside of your...

  begin
    declare
      cursor x is select dummy from dual;
    begin
      ...
    end;

• I inadvertently removed javascript, what can I do to get it back?

  When Java had security problems, I was trying to remove it from my computer in the process, I have removed Javascript and now, some web sites are not fully functional. Is there a way to get Javascript without having to remove and reinstall Firefox?

  Hello nocsra, javascript is deeply rooted in firefox - you just cannot delete it.

  Please enter Subject: config in the address bar of firefox (confirmed the message information where it appears), search for the preference named javascript.enabled and make sure that it is set to true.

  In addition, please make sure that you do not use addons like noscript, which could block the execution of JS on some pages.

• TCP (UDP) connection with Blackfin

  Hello!

  I BF-537 EZ - KIT Lite and I'm trying to create a simple server in there. I found following problem: listening TCP port does not respect the time-out: it waits until the client establishes the connection for always (value of timeout regardless). Same thing happens to «UDP read» In addition, these screws completely block the execution so the parallel loop is thus blocked. I've found the workaround: If you wrap all timed loop loops, they run all in parallel; the connection listener is still stuck and waiting forever, but the other loops run.

  Is TI WHEREAS behavior? Suggestions to combat it?

  Thank you!

  
  

• Functional global variable pending

  Hi all

  I understand, by threads of reading on the forum, that a call to a functional Global Variable will block its execution if the FGV is already consulted one another VI, correct? Is there another way that it would block, apart from those shown?

  The reason for the question is that I have a (non-reentrant) FGV which is read by 8 subVIs simultaneously (they are, in fact, the same vi, but configured for returning) and whose time strangely, access varies based on the number of the subvis running.

  In less than 5 screws are trying to access the FGV, execution is blocked (I guess, because when the FGV is disabled and replaced by a constant there is no problem with running) and access lasts less than 50ms. If this number is between 5 and 8, execution is carried out much faster. My first assumption was that FGV has not been initiated until we call the fifth sub - VI, but I don't know how to check that.

  I can understand that there is something wrong with the FGV, but can't put my finger on. Any ideas?

  Thanks in advance for any help.
