How can I enable/disable the transmission of a can frame? (filter etc...)

Hello,
I use the CAN
Transmit-periodic.vi in LV 8.5, I want to enable or disable the
transmission of a frame without stop the loop of my VI, does it exist
in the frame api a vi which could stop, or mask the transmission of a
frame?
It's important I don't want to stop my VI that
send my frame just filter a frame that I don't want send on my CAN
bus...(I would command it with a boolean for example).
Thank you.
Bye.

Hi there
I'm not familiar with NI-CAN, but take a look at
\vi.lib\Nican\nican.llb\ncAction.vi
Can be found in the CAN\Frame API\Advanced palette.
Start Transitions the CAN object from stopped (idle) state to started (running) state. If the CAN object is already started, this operation has no effect.
Stop Stops the CAN Object. For example, if the CAN Object is configured to transmit data frames periodically, this action stops the periodic transmissions. This action will also clear all entries from the read queue.

How to enable/disable the input fields based on the data entered/user action in the web dynpro abap?

How to enable/disable the input fields based on the data entered in the web dynpro application abap? If the user enters data in one input field then only the next input field should be enabled else it should be in disabled state. Please guide.

Hi,
Try this code.
First create a attribute with the name readonly of type wdy_boolean and bind it read_only property of input field of which is you want to enable or disable.
Next go to Init method.
Set the readonly value as 'X'.
DATA lo_el_context TYPE REF TO if_wd_context_element.
     DATA ls_context TYPE wd_this->element_context.
     DATA lv_visible TYPE wd_this->element_context-visible.
*   get element via lead selection
     lo_el_context = wd_context->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_context IS INITIAL.
     ENDIF.
*   @TODO fill attribute
*   lv_visible = 1.
*   set single attribute
     lo_el_context->set_attribute(
       name = `READONLY`
       value = 'X').
After that Go to the Action ENTER.
First read the input field ( first input field, which is value entered field) , next give a condition
if input value is not initial then set the readonly value is ' '.
DATA lo_nd_input TYPE REF TO if_wd_context_node.
     DATA lo_el_input TYPE REF TO if_wd_context_element.
     DATA ls_input TYPE wd_this->element_input.
     DATA lv_vbeln TYPE wd_this->element_input-vbeln.
*   navigate from <CONTEXT> to <INPUT> via lead selection
     lo_nd_input = wd_context->get_child_node( name = wd_this->wdctx_input ).
*   @TODO handle non existant child
*   IF lo_nd_input IS INITIAL.
*   ENDIF.
*   get element via lead selection
     lo_el_input = lo_nd_input->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_input IS INITIAL.
     ENDIF.
*   get single attribute
     lo_el_input->get_attribute(
       EXPORTING
         name = `VBELN`
       IMPORTING
         value = lv_vbeln ).
if lv_vbeln IS not INITIAL.
    DATA lo_el_context TYPE REF TO if_wd_context_element.
    DATA ls_context TYPE wd_this->element_context.
    DATA lv_visible TYPE wd_this->element_context-visible.

Enabling/disabling the 'display PDF in browser' via a script after Reader 9 is installed

So we have Reader 9 already installed on the machine, but we need a simple way that a user can click on a shortcut in the start menu to reconfigure how the PDF is opened - either from within the browser or outside of the brower.
In Reader 7, I was able to use this:
msiexec.exe /i {AC76BA86-7AD7-1033-7B44-A71000000002} Remove=ReaderBrowserIntegration /norestart /qb-!
msiexec.exe /i {AC76BA86-7AD7-1033-7B44-A71000000002} ADDLOCAL=ReaderBrowserIntegration /norestart /qb-!
which works well after the fact that Reader 7 is installed on the machine.
For Reader 9, things have changed, and have tried this:
msiexec.exe /i AcroRead.msi /qn DISABLE_BROWSER_INTEGRATION=YES
msiexec.exe /i AcroRead.msi /qn DISABLE_BROWSER_INTEGRATION=NO
The above don't work, nor if I run a repair instead of an install. I also tried to modify the HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals\bBrowserIntegration then following in up with the appropriate msiexec command and that didn't work
No, asking users to go to the options and enable/disable the setting isn't ideal unfortunately as it requires too many clicks
Anybody have any suggestions on this?

How do you Enable/Disable a user's ScreenSaver and set it's time

How do you Enable/Disable a user's ScreenSaver and set it's "Start Screen Saver" time.
I am writting an application in java which uses JNI and a screen saver to lock users out of the computer unless they enter the correct username and password.
If they enter the correct password I need to Enable the ScreenSaver at a specific about of time (time can be changed remotely) so I can "log out" the user.
I need to disable the screen saver after the screen saver runs so that it doesn't run while the java login program is running.
I have this working already on Windows XP but can't find any way to program this on Mac OS X.
Thank you for any help!

How to I completely disable the voice activated dialing ...

How to I completely disable the voice activated dialing on my Blackberry?

One thing you might try is going to System Preferences/Sound and changing the output from Internal Speakers to Line Out or Digital Out. Line Out would be for headphones. I assume it keeps this setting after a reboot but you should test it.
Disabling the sound will also disable all warning sounds. Those can be pretty useful.

How can I filter alerts shown in the Server app?

In the time I've been running OS X Mavericks Server, the only alert to come up in the Server app's Alerts pane is "Virus detected in inbound email". That's about as surprising as finding that water is wet, so I'd like not to see those alerts. I don't want to turn off the email filtering, I just want don't want to hear about this one kind of event.
How can I filter the alerts in general or this one in particular?

Hi ephraimephraim
I dont know if you found a solutions, but I hit the same problem so here is what I worked out...
Go to: Mac HD/Library/Server/Mail/Config/amavisd
In there you will find a file called amavisd.conf
Make a backup copy of this just incase! Now open the file using TextWrangler (its free from here http://www.barebones.com/products/textwrangler/download.html).
Now scroll down to line 119 and it will look like this:
#$virus_admin              = "[email protected]"; # notifications recip.
#$spam_admin               = '[email protected]';
#$spam_quarantine_to       = '[email protected]';
#$banned_quarantine_to      = '[email protected]';
#$virus_quarantine_to      = '[email protected]';
What I waneted to do was stop the useless "Virus detected in inbound email" emails and just send a copy of the emails to one account that I could keep an eye on, so this is what I did.
First deside on a alias to use, such as [email protected],
Now you can insert that like this virus-admin\@$mydomain its relly is important to add the \@$mydomain this resolves up the top of the file so it should now look like this
#$virus_admin              = "virus-admin\@$mydomain"; # notifications recip.
#$spam_admin               = 'virus-admin\@$mydomain';
#$spam_quarantine_to       = 'virus-admin\@$mydomain';
#$banned_quarantine_to      = 'virus-admin\@$mydomain';
#$virus_quarantine_to      = 'virus-admin\@$mydomain';
now delete the # notifications recip. after the virus_admin to stop the Virus Notifications, then I deleted the # before the spam_quarantine_to, banned_quarantine_to, virus_quarantine_to this "turns on" the line and then add # notifications recip. after them, so you should end up with
#$virus_admin              = "virus-admin\@$mydomain";
#$spam_admin               = "virus-admin\@$mydomain";
$spam_quarantine_to       = "virus-admin\@$mydomain"; # notifications recip.
$banned_quarantine_to      = "virus-admin\@$mydomain"; # notifications recip.
$virus_quarantine_to      = "virus-admin\@$mydomain"; # notifications recip.
Now just create a user on the server called virus-admin of add it as an alias using Workgroup Manger.
Hope this helps

Sorry, but I don't believe there is way that you can. You'll just have to make sure to read the minmium requirements of any App you are about to purchase to ensure that it is compatible and will run on your iPod Touch running iOS v3.1.3.

How can I filter a table from Data Control without enter query

I have a table from a web service data control based on WSDL.
I want to filter the table without input query at filter text box. Without filter text box, each would filter the table with a hardcoded query internally.
For example, when user click A menu button then it filters the table where type = '1' and B menu button filters the table by type='2' and C menu button filters the table by type=' ' .
How can I filter the table without enter query?
Could anyone point me to a solution please.
Thanks.

Hi,
when you created the table, did you try selecting the "filter" option. Select the table and go to the Property Inspctor. In the tool bar of the Property Inspector there is an icon to change the configuration. Its adding filter filter fields for the user to search in.
Option 2: The data of the Web Service actually is held in the iterators. If you wanted to filter the WebService query, I would not use the WS DC but a JAX-WS proxy in a POJO to fetch the WS Data. Then have the Data Control created from the POJO. You could have a method exposed on the POJO that allows you to filter the internally held data

Hi flegno,
Depending on which version that Firefox is on, currently in the Simulator is looks like there is only a way to pin the apps that result in a searched category. Searching for people in contacts who have a particular app installed does not seem to be an option? However I cannot know for sure.

How can I filter or block foreign language emails or email addresses

How can I filter or block foreign language emails or email addresses??
TIA
C

Most email clients have a provision to create a 'rule'. The rule examines the email as it is received. In generally you can search for specifically senders, recipients,subjects, or specific content words in the body. Based upon the findings of the rule, you can do something with the email (such as end it directly to the Trash).
For example if you know where all of valid you emails come from, you can create a rule that checks the from field for an acceptable sender and sends those email's that to the inbox, while sending all emails from other senders to the trash or spam folder
Keeping out foreign language emails is often difficult because because often it is difficult to come up with a rule that will catch them on the basis of language they are written in.
There are also commercial products that can scan incoming email and 'score' the email based upon content, and you decide at what 'score' you want the mail sent straight to the trash or spam folder. Verizon's spam filter does this based upon Verizon's scoring system, and actually does catch a lot of spam. It also occaisonally catches things that are not spam however....
Hope that is helpful

How can I filter my 500+ email contacts to just those I can facetime chat with?

You will need to remove it as your rescue email : log into your account via the 'manage your apple id' button on http://appleid.apple.com, select the 'Password And Security' section on your account's screen, and answer the two security questions that show - you should then be taken to another screen where you can change or remove your rescue email address.
Then try logging out of your account and then log back in and see if you can then use it as your primary email address.

How can I filter thermocouple noise using a TC-2095 and SCXI-1102c?

Hello all,
I currently have four TC-2095s connected to SCXI-1102c cards inside a SCXI-1001 chassis. These thermocouples are floating and I have been getting a fair amount of noise (3-phase 400 Hz and even 60 Hz noise) when we power on some equipment such as blowers and fans. Using this current set up, how can I filter the noise? Or do would I need to set up a new hardware configuration (i.e. SCXI-1102 cards)?
Solved!
Go to Solution.

Hi RALoo,
The 1102C has a lowpass filter with a cutoff at 10kHz, so you will not be able to filter in hardware with your current setup.
Your first option would be to use a software filter. LabVIEW has several functions which accomplish this. More information on this can be found here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvanls/filter_vis/
The second option would be to change to SCXI 1102 cards as you suggested. The lowpass filter of the 1102 has a selectable cutoff frequency at 2 Hz, which will stop the 400 and 60Hz noise from affecting your readings.
