How to use NI CAN feature for extracting DBC information without a CAN Interface?

Hi,
I'm looking for some tricks in order to extract DBC Information using the NI CAN without a CAN interface...
Basically I have some DBC files and I would to analyze them to get hierarchy Messages and Channels (and their related information, offset, scale, etc.).
http://www.ni.com/white-paper/4294/en/
The function CAN Get Names is usefull and allow me depending on the mode to get a list of the Channels and Messages described in the DBC file. However, I'm encountering one major issue and none of the least, I cannot use the function the CAN Get Property... As it required a connector based on Task that I cannot provide since I dont have any real and physical CAN interface, for now. Therefore I cannot have any information about the channels neither about the messages...
Does anybody can give me a hand to fix that matter?
Solved!

It seems that no matter the virtual port I am using, it does not work. Could you have a look at my sample.vi, I know it's poorly wired, especially since I'm more in .NET things than NI from my occupation ^^'. I also provided a dummy DBC file to simulate a very basic input.
And by the way is there any way then to get the Byte Array / Bit Array corresponding to a certain message (and how to set the signal values required to get the message)?
Your code isn't that bad, relativly easy to follow. In any case the problem had nothing to do with the CAN port being used. If you would probe the error wires around you would see that coming out of the CAN Init Start stated that the channel name didn't exist. Looking at how you had it wired you took the messages (or frames) and put them into the channels terminal, when I assume you wanted the channels. Then looking at your tree you were again trying to get the ID of a channel, but giving it the message name. I also added reading the Start Bit, Number of Bits, and Byte Order for all the channels read.
If you were to do this with XNET there would be completelly different functions, but the same operations can be done.

HT1893 I just bought a MAC and can't figure out how to use the scan feature on my RX580 HP printer. Can anyone tell me where to find this? This used to be an option that was obvious under programs with my Dell. Please someone help!

I need some help! I was able to download my HP printer software on to my Macbook Pro, but cannot find the Scan feature on the computer to be able to scan a document. If someone could LMK what I need to do, or where I need to look to find this I would appreciate it!

That would be a function of the driver that came with the printer. Make sure you have the latest driver appropriate to your system, either from HP or:

How to use the "identify" feature in new 6.3.1 airport utility?

how to use the "identify" feature in new 6.3.1 airport utility?
so you can find the basestations in larger networks?

There is a workaround, which is to use Airport Utility 5.6.
I can confirm that 5.6 will run on 10.8.4 Mountain Lion, it will recognize the new 2013 Airport Extreme Base Station (A1521) running firmware 7.7.1, and it will give you access to view the device's Log & Statistics, DHCP Clients, and Profiles.
Four caveats:
1) The easiest way to install it is to download the app itself, not an installer or through the App Store. There is a page here where you can download the app: http://coreyjmahler.com/2013/03/08/airport-utility-5-6-on-os-x-v10-8-mountain-li on/ This way, you still have both versions, Airport Utility 6.x.x and 5.6.
2) When you launch 5.6, you'll get a message saying a newer version is available and asking if you want to update. Click Cancel to proceed into the utility.
3) When you click the Manual Setup button in 5.6, you'll get a warning dialog that "This version of AirPort Utility doesn't support this AirPort wireless device and might improperly configure the device if you continue to use it. Check www.apple.com/support/airport for the latest version of AirPort Utility." You can click Continue to get into the utility without issue.
4) You should probably only use 5.6 to view the additional status details. I have not tried to modify and save any AEBS settings using 5.6. There are other discussions here in the forums indicating that attempting to save settings via 5.6 that are no longer available in 6.3.1 will not actually save the settings to the AEBS even if both utilities indicate that the settings are changed. See https://discussions.apple.com/message/22677993#22677993
So, even though you can't use it to modify settings no longer available in Airport Utility 6.3.1, using Airport Utility 5.6 to view DHCP clients, Logs and Statistics is very useful for troubleshooting network issues.
PS - There are two ways to get to the DHCP Clients list, neither of which is obvious The first is to go to the Airport pane -> Summary tab and click on the "Wireless Clients:" label in the Summary display. All of the labels from "Wireless Mode:" down on the Summary display operate as links to view/edit the corresponding info/settings, which is also not obvious at first glance. Also not obvious, clicking on "Wireless Clients:" actually brings up a new pane with three tabs: Logs, Wireless Clients, and DHCP Clients. You can also get to the same pane by going to the Advanced pane and clicking on the Logs and Statistics button.
I hope this is helpful information. Took me a while to find out how to do this.

How to disable the vibration feature for the Alarm?

How to disable the vibration feature for the Alarm?

Hi guys , because we have no answer to our issue how to take off the vibration when alarm is on , and our other profiles like ringtones, messages , reminders and so on we need to keep them on vibrate mode , the best solution is to install a free application from store called "alarmed " ; I did put it down on my phone and now i can use the alarm clock without any vibration at all ! That's the answer to our issue , before Apple is going to find a solution !
Personally , I don't think is going to be fix it soon , as long as the apple script made for pop ups is general one !
Good luck everyone

How to Use the same iview for both KM End User and the KM Administrator

Hi friends,
*This is my scenario :* How to Use the same iview for both KM End User and the KM Administrator but with different Context
Menu Options.
i followed these steps but im getting same context menu for both KM End User and the KM Administrator .
Assign the role Content Administrator to the user km_admin. This is needed so that km_admin can change
the presentation settings for the KM Folder u201EReports_kmFolder‟.
Now, login with user km_admin. Navigate to the Km Folder reports_kmFolder through Content Administration
-> Km Content. Click on Details link of the folder reports_kmFolder.
Go To Settings -> Presentation. Click on the tab u201ESettings for You‟-> Click on button u201ESelect Profile‟.
Select the radio button corresponding to u201Elayout Set‟, and choose u201EConsumerExplorer‟ from the dropdown.
Click u201EOK‟.
Select both the check boxes corresponding to Items Affected as shown above, and click u201ESave‟
Now, remove the u201ESuper Administrator‟ role from the user km_admin and login with this user.
How rto resolve this????
Regards,
Prasad.

Hello Prasad,
Most likely the user km_admin still has system principal roles assigned, even though you removed the Super Admin role, you should check that this user doesn't have any other admin roles, otherwise it will be considered a System Principal user and will therefore still have access to all content. For more information see http://help.sap.com/saphelp_nw70/helpdata/en/19/56f28fbd4e11d5993b00508b6b8b11/frameset.htm
Try creating a new user with just read access to the content and you should see that it will not be able to make any changes etc.

Lorcan.

How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?

Hope to you a very happy new year,
I have two differnt LAP 1300 and 1200 in my network and I need to add theme to the WLC,
I successed to add one of theme by the option 60 in the DHCP pool at the Core SW,
So my quetion is below:
How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Thanks in Advanced,
Ahmed,

To add to Scott's post. Option 60 would be useful if you needed to put certain types of AP on specific controllers. Otherwise, no real need to use it for the most part.
Though, I do recall an issue a few years ago that some windows machines had issues getting DHCP if option 43 is being returned.
Now, on an IOS switch, you can only configure one option 60 per DHCP scope

How to Use the language function for assignment and validation

Hi All,
If anyone can explain me in details with example ,how to use the language function for assignments and validations?
Thanks
Arnab

Hi Arnab,
The expression is checked only for the current MDM session.
If u login with the ABC language it will always show the ABC language no matter how many times u execute it.
Try connecting to the DM with the XYZ language.
It should go to the if part rather than else.
Hope it helps.

How to use an authenticated user for a proxy call

Dear all,
I am currently working on a JEE application where the user needs to authenticate (for this I have configured the web.xml).
Now inside this application I need to do a proxy call to a PI webservice.
I would like to use the user credentials of the already logged in user in order to call the proxy.
What I don't want to do is to use a service user for the proxy call.
The code I am trying to call looks something like this:
     private IntegratedConfigurationIn getPort() throws Exception{
          IntegratedConfigurationIn port = null;
          try {
               IntegratedConfigurationInService service = null;
               service = new IntegratedConfigurationInService();
               port = (IntegratedConfigurationIn) service.getIntegratedConfigurationIn_Port();
              BindingProvider bp = (BindingProvider)port;
              bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, user);
              bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);
              if (url.length() != 0)
                   bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url);
          catch (Exception ex){
               ex.printStackTrace();
          return port;
The examples I found to retrieve the userdata pointed to codes similar to this one:
public HttpServletRequest getHttpRequest() throws Exception {
          // Get runtime context
          Properties props = new Properties();
          props.put("domain", "true");
          Context initialContext = new InitialContext(props);
          ApplicationWebServiceContext wsContext = (ApplicationWebServiceContext) initialContext
                    .lookup(" /wsContext/ApplicationWebServiceContext");
          HttpServletRequest req = wsContext.getHttpServletRequest();
          return req;
com.sap.security.api.IUser sapUser = com.sap.security.api.UMFactory.getAuthenticator().getLoggedInUser(getHttpRequest(), null);
          IUser ep5User = com.sapportals.wcm.util.usermanagement.WPUMFactory.getUserFactory().getEP5User(sapUser);
Now I don't know how to bring it togehter and how to use an authenticated user for the BindingProvider.
I would appreciate any hints or ideas.

Peter,
from the first screenshot, what I understood is that, you are calling an inbound PI web service that is intended to create an integrated configuration object (this is used for whole lot of other reason completely) but not actually calling a development web service.
For this, you would have to generate your client classes from the WSDL provided by the PI developer for that particular service. Once you get those client classes generated, you could used the method provided in the other screenshot to extract the user and password and call the intended web service.

How to use the Validate step for Approve step

Hi Experts,
I have modeled a workflow with the steps start,process, validate, approve, process and stop.
Process is set to owner and approve is set to some other user user1.
My requirement is as follows :
1) Approve the records by approver and then it should send it to the next step for further processing
1.1) if the approver did not approve the record it should send a error message until the record is approved. So it should not send it to the next step when record is not approved
I am using a field called item status for approving and disapproving the records. My validation is based on this field only... Validation working fine when i tested it manually.
But my issue is when am using this validate step in workflow design validation is getting triggered for all the users.as per my requirement only approver should get the error message.But in my scenario owner is getting the error message and approver is not getting any message.
How can i use the validate step only for particular step say approve in workflow.
Can anyone please help me out how should use validate step only for approve step...
Thanks & Regards
Sireesha.
Edited by: sireesha esukapalli on Jun 17, 2008 2:48 PM

Hi ,
I have set the validation property to "None".
My design is as follows :
start->process->validate->approve->stop.
Owner is assigned to process step and approver is assigned to approve step.
Now my problem is owner is also getting this error message along with the approver. AS per the design both process, approve users are getting the error message.
As per my requirement only approver should get this prompt but not the owner.
How can i restrict only for specifc user to get this message.
Can anybody please advice how can restrict the owner to not get this error message...
Thanks & Regards
Sireesha.

How to use Spell-check functionality for textbox (like Orkut, gtalk)

How to use Spell-check functionality for tex Hello Friends,
I am working on a JSP application. I wanted to add Spell check for text box like we have here, when we post a message. It automatically shows red line under the word, when ever spelling is wrong. Please tell me how I can do this. If possible, the code too.
Thanks.

I believe the spell checking you see here, or on any other site, is the spell checking built into Firefox. At least that's what I see. Are you using Firefox?
