• What is the best approach for a same code used for 16 test stations

  I write code for 16 testbeds that are all the same, except that different circuits CAN are used, i.e. CAN0 through CAN15. The approach that I plan to use is 16 screws, one for each test station executes independently and in parallel, meaning that they can be stopped and started at different times. Each of the 16 screws have about 10 complex subVIs that are all the same. Even if I do not use uninitialized shift registers, I wonder if there is no advantage to using a reentrant approach, or even if it works for my application. Any suggestions are appreciated as I have no experience using the reentrant approach.

  Thank you.

  First of all, you should get used to use projects. They are very useful. If the code is in a project, you can open the VI from there.

• Change the default profile for networks not identified in the register.

  Hi, I recently installed a copy of Windows 7 Home Premium. Recently, I tried to share files on a network computer to computer without router. I ran into problems with this, however, because Windows will just recognized here a network not identified, set its profile to the public and turn off sharing. I am aware that the default profile is editable through the local security policy editor, but being on the House, I am unable to access it, so my question is this:

  Is there a way to change settings of network profile for networks unidentified somehow outside the local security policy editor? (via the registry)?

  Hi Konaa,

  1. Click Start, type Regedit

  2. find hklm:\SYSTEM\CurrentControlSet\Control\Class\ {4D36E972-E325-11CE-BFC1-08002BE10318}

  3. find your network card adapter and create a dword value named "* NdisDeviceType" and change the value between 0 and 1 and enable/disable network cards.

  You can also try this:

  1. the Registry Editor open, if you are prompted for an administrator password or for confirmation, type your password, or click on continue.

  2. Locate and then click the following registry subkey:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}

  This registry path, click the (GUID) subkey that corresponds to the card network that is connected to the network.

  3. on the Edit menu, point to new, and then click DWORD (32-bit) value.

  4. in the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.

  DhcpConnEnableBcastFlagToggle click 5.right, and then click on edit.

  6. in the value data box, type 1 and then click OK.

  7. close the registry editor.

  Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.

• What is the best approach to the conversion of the LV7.1 tags to the variables shared by several screws LV2012?

  What is the best approach for the upgrade of the DSC-LV2012/LV7.1/DSC static variable tags in several screws running on several platforms? Our system is made up of about 5 PC running Windows 2000/LV7.1 DURATION, the more a PLC and a PDC running XP/SP3/LV2012. About 3 PC publish information from the sensor through tags on the local network to the PDC. Only the main command is currently being upgraded. Basic questions:

  1. the other computers running RTÉ 7.1 (with labels) will be able to communicate with the PDC running 2012 (shared variables)?

  2. is it necessary for conversion of tags shared variables, or the deprecated legacy tag screws of LV7.1 work in LV2012?

  3 all of the main controllers will be screw must be integrated in a project in order to use shared variables?

  4 is the only way to do it is to find all the tags and replace them with elements of shared variable?

  Thank you in advance with all the information and advice!

  Hello

  You have a Realtek Lan card?
  If Yes, then you should contact the ASP in your country for a fix.

  I had a similar problem with my card Realtek Lan on a Satellite A110. From time to time my system locked up for the big copy via the port LAN Realtek.
  I talked to a local technician and he said to a patch.

  Unfortunately, I put t know what he did, but after the update (or install the fix) I didn't noticed the same problem again.

  So I recommend to contact the authorized service partner and request the hotfix.

• Calculate the fastest path between 2 nodes with the data model for the Oracle network

  Hi all,
  
  I have Oracle 10 g 2.
  
  My problem is the following:
  
  I created a network named ITALIA_NET in the data model for the Oracle network.
  The table of links of this network is named: ITALIA_NET_LINK$.
  The table of the nodes of this network is named: ITALIA_NET_NODE$.
  
  The table ITALIA_NET_LINK$ contains a field named COST that contains links (in meters) lengths.
  
  I've already calculated the SHORTEST PATH between two nodes of the network, by using the method of shortestPath() (using the Java API) as shown on "Pro Oracle Spatial for Oracle Database 11 g" manual. Infact, this method makes reference to the COST field for $ ITALIA_NET_LINK to make this calculation.
  
  Now, I want to calculate the FASTER PATH between two nodes of the network. I have the links (in hours) travel time to make this calculation.
  
  My idea is to create a new field in ITALIA_NET_LINK$ named Cost2 containing the travel time from the links and then do the math by using the shorthestPath() method, referring to the Cost2 field to $ ITALIA_NET_LINK COST field instead.
  By default, I know that the shorthestPath() method returns the COST field for $ ITALIA_NET_LINK. Is possible to change this setting and do that this method refers to the Cost2 field?
  
  In the alternative, is another way for the calculation of the fastest way?
  I want to leave the creation of another network as last solution, because I will have other costs of field (Cost3, cos4t,...)
  
  Thank you much in advance.

  Your approach is good. You will have two networks and you can read them in memory and analyze of shortest path. The shortestPath method is static for the class of NetworkManager. You can use the same method for both networks, once they are read into memory.

  ...
  read the network with time as cost of link
  NetTime network = NetworkManager.readNetwork (dbConnection, 'ITALIA_NET_TIME');
  read the network length as cost of link
  Network netLength = NetworkManager.readNetwork (dbConnection, 'ITALIA_NET_LENGTH');

  calculate the quickest way
  PathTime path = NetworkManager.shortestPath (netTime, startNodeID, endNodeID);
  calculate the shortest path
  PathLength path = NetworkManager.shortestPath (netLength, startNodeID, endNodeID);
  ...

  In the future, if you upgrade to 11g, network data model provides a load on demand (LOD) API that loads only the scores of necessary network in memory during the analysis. This command removes the restriction of the memory of the 10g (in memory API you use) API. API of LOD can handle very large networks and offers more features analysis and modeling capabilities.

  The following link contains the tutorial of NDM LOD API ready for download. Just for your information.

• Best approach for the design of the Radial Image - sector scanning Sonar

  This is not a problem, but you are asked to think about the best approach.

  I need a sector sonar image data.  This device runs on 360 (degree sub-segments) and generates a set of data from the origin - radially outwards at an angle of no - to an endpoint.  Therefore, for each 'ping' sonar I need data points in the center of a circle graph, a radial angle on the outside.

  I don't know if I should use LabView vi for the drawing tools, or go to ActiveX or?

  Anyone has a suggestion on the best approach to this?

  Thank you
  Peter

  Peter,

  You can use a chart of the LabVIEW intensities for this kind of display.

  Maybe not the best way, but it is possible.

  As an attachment, I did an example with your specifications.

  datapoints 1024 by degree

  See example image:

  

  Basic principle:

  -Create the matrix of 2048 x 2048 points database

  -For each 'line of angle' calculate which pixel to replace each data point in the line

  -Because "datapoints" becoming bigger, far from the Center, repeat the action for several "sup angles. for example, to 85 deg also Calc. 84.6, 84.8, 85, 85.2 85.4

  It gives you an idea of the possibilities, but performance may be necessary.

  -Only external Calc x pixels more degrees

  -Do some kind of anti-aliasing to avoid the pixelated lines.

  See attached example. (LV 8.6)

• Windows XP Pro SP3 slow navigation and performance of the Internet network

  I am running a Windows SBS 2008 domain with 70 clients - many of which are Windows 7 Pro (and not affected by performance problems) and other clients are Windows XP Pro.  Recently, apply 2 updates to all Windows XP clients to a problem of double authentication with RDP Server 2008 platform - two updates are http://support.microsoft.com/kb/969084 (install the RDC 7.0 client upgrade) and http://support.microsoft.com/kb/951608 (adds the registry entry in Windows XP to enable CredSSP).  Now, the patches of handsets allow RDP clients to Server 2008 platform and enter the credentials of the user only once.

  However, given that these updates have been applied, about 7 of 20 Windows XP clients are extremely slow performance when searching for network resources (sharing drives, Outlook / MS Exchange and Internet browsing synchronization).  Not sure if the 2 patches are coincedental or related.  I tried rewriting changes from two patches, drivers NETWORK card and even tried to replace the NETWORK adapter with new ones.  No change in performance.

  However, can I uninstall / reboot / reinstall the Client of Microsoft Networks and clients perform as expected.  Over time (sometimes), the problem reappears.  I have been through the event logs and don't see any errors that indicate a failure to communicate on the network.  All clients receive assignments IP from the DHCP server and updates are managed via WSUS.

  Ideas or recommendations would be greatly appreciated.

  Hello

  I don't know if I understand your question, but you want to connect two laptops via the WLan. Am I wrong?
  Well, this type of network connection is called Ad hoc.

  Choose Start-> settings-> network connections, and then click the local network connection you want to share. On the left side of the screen under the management of the network, click on "change settings of this connection. Under the Advanced tab, under Internet connection sharing, check the box "allow other users of the network to connect through this computer's Internet connection".
  There is also a check box to allow other users to enable or disable the Internet connection, if you are so inclined. If your network doesn? t need to access to the Internet, you can skip this paragraph.

  The host system must also be configured with an Ad Hoc network connection and a Set Service identify (SSID). Right-click on the wireless icon in the system tray and choose "view wireless networks". Do NOT yet connect to any wireless network that could appear in the box. Click the Advanced button. This will bring up the Properties window of wireless with the wireless networks tab at the front. Click the Advanced Options button at the bottom right of this tab, select the option "networks from computer to computer (ad hoc) only". Make sure that the box "Auto connects to the non preferred networks" is NOT checked. Click the close (once) button to return to the wireless network tab.
  Under preferred network, click Add. You now need a SSID for this machine, which is actually the name it will use to announce themselves to the other members of the ad hoc wireless network.

  Hello

  I guess you need a Wlan card and LAN driver card.
  I a little surprised at your comment, because the WLan and LAN drivers are available on the page of the Toshiba m driver.

  There are 2 Intel Lan and 4 Wlan drivers for different wireless cards. You must choose the right! ;)
  Check the bottom of the unit. There must be a label with a few s Lan and Wlan card information.
  Select the correct drivers and install it.

• 'For' loop with a different number of iterations. Second, the auto-indexation of the tables with different sizes is done. It can affect the performance of the Vi?

  Hello

  I have a loop 'for' which can take different number of iterations according to the number of measures that the user wants to do.

  Inside this loop, I'm auto-indexation four different 1 d arrays. This means that the size of the tables will be different in the different phases of the execution of the program (the size will equal the number of measures).

  My question is: the auto-indexation of the tables with different sizes will affect the performance of the program? I think it slows down my Vi...

  Thank you very much.

  My first thought is that the compiler to the LabVIEW actually removes the Matlab node because the outputs are not used.  Once you son upward, LabVIEW must then call Matlab and wait for it to run.  I know from experience, the call of Matlab to run the script is SLOW.  I also recommend to do the math in native LabVIEW.

• What happens when "Still waiting for network when starting the computer and logon" is enabled and that the computer is not connected to the network?

  In MMC, I created the group policy and found through web search that computers with mapped network drives can connect better if "always wait for network when starting the computer and logon" is enabled...  So far, it has been very nice to have allowed.  Is no longer mapped network drives see the place as disconnected.  But what happens if the computer is not connected to a network?  Say the wireless router will turn off and your computer always 'wait... '. "turned on, should the user could still log the computer timely?
