• Best method of communication between the Application LV

  Hello together,

  I'm looking for the best way of communication between two Applications LabVIEW. As VI is clear, I can use a queue or a global variable and so on.

  But what is the best, when I compile the screw later for DLLs or Applications. So far, we always use the TCP/IP Protocol, but I think that there must be a better way instead.

  So if someone has an idea - he is welcome.

  Thanks in advance

  What I don't like with TCP/IP you still need a second thread (looped) who manages the TCP/IP communication. I thought that there must be an easier way.

  I also thought that shared variables are always limited to a single application. Thanks for the ideas...

  This second loop is a loop that YOU control. If you go with shared variables you are a slave to what they can or cannot do. In addition, they work over TCP/IP is not out of the picture.

  Its your call.

• Data connection between two applications

  Hello world

  Is there a way to open a connection of type 'stream' between two applications without using the file system?  Writing on file seems too gross.  Surely someone does this!

  What I found so far:

  Object 'Event' does not seem to do... DOM seems to be communication within an application or suite.

  "Socket" seems to be ruled out by security, but no official word on this issue...

  "Then" explicitly says that only one application can access a serial port at any time...

  Class interface 'Connection' seems to have many children (taking one) but all seem to be dead ends.

  Anyone?

  Thank you

  DD

  I suggest using a global event. You can attach an object to the event and look to the other application.

  See the documentation for the API of ApplicationManager.postGlobalEvent () and the GlobalEventListener interface.

• share data between two applications

  I would like to know if there is a way to share data between two applications of MXML or more?
  
  Using the class SharedObject can operate only in a single application, but if you start a second request, this SharedObject does not its value (zero) already set from the first application.
  
  Thanks for your help!

  I remember correctly, there is a setting to allow work between applications. Also you must be sure flush() to save the data.

  Another option is LocalConnection.

• I want to create communication between two laptops by Bluetooth series

  Hello

  I'm trying to accomplish communication series between two laptops via a Bluetooth connection.

  The two laptops are NOT portable Toshiba, but they work together the Toshiba Bluetooth Stack For Windows. They have both also use the default Bluetooth Manager program supplied by Toshiba and Dell (just rebadged?).

  Basically I can set up a connection no problem, but then I have never send data serially from one computer and watch the receiver serial port on another computer but nothing happens.

  Is there a good tutorials for this? It would be nice to have something for the Toshiba Bluetooth Manager especially windows and buttons have names as explained in the tutorial.

  Thanks in advance.

  Adam

  I tried via a hyperterminal connection for testing purposes and it worked.
  Maybe the description also contains useful information for you.
  It is here:

  PC1:
  Start "Bluetooth settings-> Mode custom-> Select Remote PC-> Select"Serial Port"-> Accept proposed (in my case COM40) COM-> Confirm Assistant windows port
  until the installation is completed".

  PC2:
  Start 'HyperTerminal-> Select COM7.

  PC1:
  Start 'HyperTerminal-> Select COM40 (in my case. (See step 1 above) »

  PC1, PC2:
  Enter the password even if security is enabled for example "0000".

  PC1:
  Everything you type in HyperTerminal must be visible in HyperTerminal of PC2 and vice versa.

• GPIB communication between two computers

  I try to communicate between two computers via GPIB. A computer to send an order, the other will receive, save and then respond accordingly. This response will then be received by the first computer and displays (this is the emulation of a device, the real need is to communicate with a satellite TT & C)

  I realized all of this. However, to be in listening mode I wired a property node with a timeout-infinity (1) before reading. Now I can't leave the VI as he is still stuck in playback until the receipt of an order.

  How can I get out of the VI when he's stuck in playback function.

  PS: Using GPIB for communication is a requiremnet of ht eproect and cannot be replaced.

  Hello

  You can have the timeout of read and then clear the error and keep looping until you get a message.  And then you can use arithmetic consisting of stop the loop if you click on the stop button, or get one error other than a timeout, or if playback returns data.

  If it works for you?  I joined your 'writing and then read.vi' with the added code.  Double check my logic, I'm sure it's just but not run it.  Also, if you return a large amount of data make sure that the time-out period is sufficient.

• TimesTen - Communication between two DSN

  Hello
  
  Currently I have a setup in Oracle DB in which there are two databases and objects are accessible in all of these databases via the link/synonyms database.
  
  Now, I need to replicate that in a Cache Timesten InMemory DB underlying of Oracle databases configuration that would involve the creation of a link between two DSN names stored on two different servers.
  
  Can you guide me on how to go about it.
  
  Thank you
  Karan

  Unfortunately there are several constraints here that aren't going to help you:

  1. when using the TimesTen "cache" feature a single TimesTen database can only cache data to a backend Oracle single instance. Only regular tables can be cached (not views, dblinks etc.). So, if you have two instances of Oracle Db and you need data in cache at the same time you will need two TimesTen databases.

  2. as mentioned, TimesTen does not support dblinks, remote queries or queries/transactions distributed between various databases TimesTen (well, what he does in some circumstances, but anything that will help you I think).

  3 TimesTen can replicate data between different databases TimesTen, but in general you can not use the level replication table with cache tables.

  So I think, to adopt TimesTen in your application as an important architectural work may be necessary. Only you can be the judge of that, of course, but considering this please keep in mind the constraints above.

  Kind regards

• Navigate between two applications in the same workspace without sing again

  Hi all

  Version 4.1.0.00.32 of apex. Oracle DB version 10.2.0.3.

  I have two applications built in the same workspace, if a user can log on to two applications with the same user name and password. I'm looking to put a link on one of the applications to direct the user to the other app. Is there a way to avoid name of user and password to re-enter once the user clicks on the link? I noticed that the session ID is application + user. Not by the workspace + user.

  Thank you
  Sinan

  Change the properties of authentication scheme in both applications and set the name of the Cookie to be the same.

  As long as the session ID is maintained in the links, you'll be fine.

  Each application will allow authentication in your applications, but only after the relevant authentication will trigger.

• comparison and fusion between two applications

  Hello
  We run APEX 3.1.1. I have an application (say 101) production that has about 80 pages. I started a project to create more pages and references of web service and other things. It was supposed to be done in a month. so, I cloned application 101 to 102 and began with my changes in 102. at the same time any request for a quick change of the production team is a 101 application, so that the results are visible instantly.
  
  now I have finished my work at 102. and 102 is ready to be the application for production. My problem now is, how do I get minor changes, I did several times in app 101 to 102?
  
  I tried to export the two applications and sqls against them, but these sqls are very large and there is a margin of error as you more the text of 101 to 102. There must be a cleaner way to do what I'm not aware of.
  
  Any help is appreciated.
  
  Abdul-

  I would say that you need to implement the changes manually. I understand the question:

  You have two applications: App A & App B

  Both applications are in the same space and work under the same version of the APEX. You did changes in both A & B (change a region in the App, change the text of a label to the App B)?

  You will probably have to open each application separately and just start their merger manually. Best suggestion, the application you have worked last, copy your starting point and open the other application and start to copy songs on...

  Thank you

• Communication between two hosts on the host only

  I have a host ESXi 5.5 with two reviews, a Linux / Centos 6.5 comments and a guest Server R2 2012.

  I've muddled through many questions - time zone, being the biggest problem, but am confused on how to get these guests to see one another, not even sure what to put in Google.

  My goal is to be able to share files between the two guests and access their consoles with putty and RDP, but I can't make them one ping to another. Everyone on the LAN can connect these two guests, but they cannot see.

  A kind soul told me that I forgot?

  Thank you

  Hey katycomputersystems,

  Could you give us a quick screenshot of your vSwitch / Port groups.

  Of the IP information you should be able to ping to each of the systems if they are on the same vSwitch / Portgroup / VLAN.

  Try this

  vSwitch0

  VM Network - Port Group - VLAN 110 - physical Nic don't matter we will keep all the VMS on this port group

  Configure all your VMS on the port network of VM group.  As long as all the VM living on the same port group vlan and vSwitch traffic should never leave this vSwitch and each VM must be able to communicate with each other.  If not you can always ping each other take off the VLAN and try again.  Make sure also that you have no firewall or tables ip enabled on the operating systems that could prevent communication.

  If the OP calls between the ears, local EJB calls should not be used. EJBs them must be used within a unit deployed (i.e. an ear).

  If the ears are in the same VM then local can be used. Local's VM not even the same deployment unit. If it of a good idea or not is another matter.

• Focus between two applications

  Hello

  I work with both applications at the same time, which is made with CVI and the other not (e.i. Explorer). The application made with CVI every 20 seconds displays a new Panel and take focus (hence the other app lose focus), but I would still keep the emphasis on the second request (Explorer). Is this possible?

  Thank you very much

  Daniele

  Danielle:

  Matteo has given you some useful links if you want to give your app focus.  But when I read your post, it looks like your application takes the focus and you don't want it.

  The attached sample project shows two ways to allow another application to keep focus when your application will normally consider.

  Both methods use the Windows SDK functions (a.k.a. Win32 API) to get or set the foreground window (the one with focus).  The Windows SDK is not installed by default with CVI.  It comes with the full package and the Suite OR developers, but not with the basic package.  If you have the complete package or suite, and you do not have the SDK installed, you just re-run the installation of the CVI and select only the SDK (or Win32 API).

  The basic idea behind the first method is that before you post your new Panel, you check to see which window is in the foreground by using GetForegroundWindow(), then your new display panel and then set previous window of the application in the foreground using SetForegroundWindow().  The downside of this method is that your new Panel has a quick flashing of focus before focus is returned to the other application.

  The second method checks if your app CVI is the foreground window before displaying the new window.  It does not display your new Panel if another application has the focus.  This way you don't get the blinks of update to your application CVI.  Depending on the purpose of your new Panel, you may have to display the new Panel when your application receives the focus instead to wait until 20 seconds to display.

  For demonstration purposes, this sample application appears again just the main draw instead of display a new Panel.  The two methods will be work the same way for a new Panel as well.

  Instructions for running the demo and see the two different methods are on the main Board.  Just build the application and run it.  I tested this example in CVI 6.0 and version 9.0.1.

  Having said all that, I have a question for you.   Why your application CVI shows a new sign every 20 seconds?  You can update an existing panel without using the DisplayPanel command and forcing the update to your application CVI.  Do you need a new Billboard?  And what happens after 20 seconds?  The first Panel again get hidden or destroyed?  Are another new panel displayed?

  There could be something even easier, you can do without one of these SDK, as do not use DisplayPanel if you need SetCtrlVal.  (But this model made for a writing exercise pleasure).

• How to enable wireless communication between two clients?

  I've got a WRT54GL with the latest firmware.  I have two computers that are both connected to the router with the IP via DHCP addresses.  Nor has a firewall running.  I can't communicate with them - even ping does not work.  I can ping the router itself by using the IP address assigned to this side WAN by my ISP.   Both computers have no problem to reach the internet through the router.

  What the router settings will allow communication to occur?  I can't find anything in the user interface of the router, which seems to control it.

  Thank you.

  I just figured out the problem: Isolation AP (in advanced wireless settings) has been activated.  I turned it off, and the problem is solved.

• Communication between two network cards on windows 2003

  Hi all

  I need your help.

  I have a machine virtual windows 2003 with two network adapters.

  NIC 1 - external - 192.168.1.101

  Map NETWORK 2 10.10.10.1 - internal -.

  I've configured to operate as a DC and DNS serving 10.10.10.x network.

  DNS is configured to resolve before on 192.168.1.1 as redirector DNS requests.

  I have other machines connected to the 10.10.10.x network.

  They can ping 10.10.10.1, they can ping 192.168.1.101 but not 192.168.1.1

  I want to just be able to talk to 192.168.1.1 and be able to access the internet.

  No firewall between the two.

  Command-line may help, but I would need your help.
