Understand the invoke node

• Initialize controls/indicators: invoke node-local variables Vales. Which is faster?

  Hi all

  I would like to get the opinion of the people. This thought just happened for me while I was reading some materials the other day.

  And I have not found any topic which talks specifically about speed after searching the forum.

  It is faster to initialize your controls/indicators using Invoke node OR write directly to the initial value of your local variables?

  From my experience (not large), I have always used the invoke node to initialize controls or indicators.

  But when I but this question, I did a simple reference point and it seems the local variable approach is faster, especially

  If you have the large number of orders/lights to initialize.

  Am I missing something here? The invoke node running something that writing a value of local variable would not do?

  I thought since you need to set the initial state by default for the node to invoke anyway, why not just write the desired initial value

  your local variables?

  I would appreciate if someone can express his own opinion based on their experience and knowledge.

  Thank you ~ ~

  I may need another Cup of coffee this morning, you are in fact callling the reset by default on each individual control.  My last despises, it is that you use the default method Vals.Reinitialize VI all failing.  It will probably be a bit faster than the method on individual controls.  Still not instant, if.

  Are a few msec is worth to you?  If so and you consider the local path, my advice is to group as many controls as possible into clusters for minimize you headaches.

• Run VI Invoke node: VI works, EXE does not work?

  It is LV2009 without patches or updates. I call buffer.vi of static reference with a collection of nodes to invoke to run a VI. I don't have a very good reason for it, but don't want this code on the block diagram. I can't wait to put a lot of effort in this since I can just drag the code on the main scheme and I am sure it will work, but I do not understand why it gives me error 1000: VI not in a State compatible with this operation?

  In the EXE file, when I check the status of the execution of the buffer.vi until I say it runs, sometimes bad. Same code in VI, sometimes slow. I also tried to replace the static VI reference with a reference open VI by using the name of the buffer and received the same error message. I have the buffer VI included in the compilation under always included.

  So I was building an example of project because I didn't post all, boredom was the example ON what EXE has no error. WTF. Then I realized that I had another call from node in the boot sequence. OOPS. I put that in there thinking that the only way it would be mistake was if the VI was running before he called, in this case I wanted an abortion there. It turns out also-error (1044 locked VI) when running in an EXE file, even if this particular node using says he works with the runtime. SO, he tried to abort a VI that was not working. The initial error, 1000, just said not compatible with call node state, did not say that one.

  Yes, sorry for the trouble and thanks for the help. Maybe someday I'll understand the problem that I was led to this, guess who is the fact that I can't debug EXEs. Kind of, I think it has something to do with an XControl I always use it because they always appear as corrupted files just before that the debugger fails. Anyway, thanks again, I'll plug that into the real system and see what else does not work.

• calculation using the formula node needs two clicks

  Hello

  I want to use this piece of code for a larger program. My goal is to take 10 values and calculate two values using a formula. I used the formula node as the calculation functions digital ordinary would be too heavy. If I click on save, it saves two values to a file.

  The problem that I am facing is that when I start the program, it works very well for the first time. The second time however, if I change the values, and then click on save, it still displays the previous values, or some altered values. I have to click on save twice to get the correct values. I don't understand the reason why this happens. Can anyone help?

  File attachment: Capture screen and VI.

  P.S. If the solution can help with the problem, I'm ready to change any part, but please, not irrelevant to suggestions on how to * improve my code *, because I've worked hard to make it work with another major project.

  I don't completely understand the description of your problem.  But I see two problems.

  1. the "Save" button actually belongs to the event that handles the record button.  And the case of the event should really be Jean-Claude Value Change of mouse down?

  2. your STOP at the bad mechanical action.  Since it happened so this just released, it is only true while you're pressing it.  It stops the upper loop, but can't stop low loop because your loop will also be waiting to save button to press.  Stop will always be false because you cannot press two buttons at the same time.

  Try to make your action to stop button to be changed when released.  You must return the button to false programmatically born of two loops.  In fact, it would be better to have a case of events for the stop button to stop the lower loop.

  I don't understand what you're trying to do in the upper loop.  You read a file as soon as possible, and it seems to be the same file that you create in the lower loop.  Why?

• Several VI instance will not RUN using invoke node

  Hello

  I need to have multiple instances of the same VI running.

  I created a template of the VI I wan't to call several times.

  The VI is called through reference opened with a reference to the model VI VI.

  Parameters of the instance is passed via the control value.

  The opening and settings has been passed, I use an invoke node to run the VI.

  An error occurs.

  "Error 1000 in node invoke in Template_Call field window.vi.
  Possible reasons:
  LabVIEW: The VI isn't in a State compatible with this operation.
  Name of the method: Run VI
  "Path of the VI: NULL".

  Note! The screw must remain open after that call running independently from each other and that the appellant should not wait until the VI.

  Any ideas what I am doing wrong

  Just unplug input terminal to open VI reference function type specifier.

• Sorting table 2D using the formula node

  Hello

  • What l am trying to do is kind of numbers in groups.
  • A group consists of the numbers that are equal, or step upwards or downwards by a single value. Each group must be assigned to a column. E.g. O column of the table of entry test would consist of 5, 4 and 3, but not the 9 and 10. These values belong to column 1. However if the adjacent cell in the column was not empty then 9 and 10 would stay in column 0
  1. To better understand the programming formula node went to 1 d. I found that each cell is not treated individually with my code.
  • The final table of the orange entry test is that the data type l want to sort a 2D picture that ends up the same size chart.
  • In the code l provided my goal to compare each cell of each column line to determine if a cell is equal for example a = b, a + 1 = b or a-1 = b If Yes, then these values are in the right column. If this is not the case, a sort must be made to put a value in the right column it is.

  This is my first shot with node formula and l must admit others examples l found a bit confusing how a result has been obtained. I prefer to do any programming in labview instead of going to another program for results l am after. I tried to picture of programming just for this problem and found to grow big and very complicated then stopped l. For me the road to node formula should be simpler and more compact. My last resort is to use Excel but l still hope to do all the programming in Labview l you end up with a more dynamic program.

  Concerning

  Michael

  Hello

  You are brilliant... bloody!

  I just couldn't she would repeatedly using tables, l have been on it for weeks. I never thought about how you solved this problem.

  I hate excel and text. I am graphically spirit therefore l such as labview.

  I had a solution in Excel yesterday, but your solution is much better than what l came with

  I'm very grateful

  Thank you

• Set of geometry invoke node: do not have this method (and why is it red?)

  Hi all

  So I take my first steps with the 3D picture control, and I stumbled over the first hurdle!

  How to create a 'set of geometry' call, node, as shown in this photo? If I have the wiring in the output of the object to create an invoke node I get a standard invoke node with several options, but none related to the geometry.

  Second question: why is the Red node to invoke?

  Finally found the reason:

  alignment has been deprecated in LV8.5, from the help:

  Obsolete properties, methods, and events

  LabVIEW 8.5 does not support the properties, methods and events:

  • Property of the geometry of the SceneObject class. Use the Drawable property instead.

• String reconnaisable invoke node

  Hello everyone, I am new user and a beginner in Labview programming.
  I created a VI to ping device in lan ethernet (of which I enclose a picture). VI watch just so has green led "ping-pong."
  I'd use the same node to invoke with an array of string costant, I can't do it.

  Thank you very much.

  Hi nellooo,

  Here's the "autoindexing" and "loops" at stake!

  Use a loop FOR autoindex on your input string array. (And you need a control of the chain, not an array of string constants array.)

  Because it's pretty simple, I suggest you to go through these free online courses offered by OR!

• How is the bow sheet 12 c Flex cluster connected to the Hub node?

  In 12 c Flex, Oracle said that we can install the database of 12 c in hub node and nodes leaves are clients of the DSO.

  I want to know if I can configure my application as terminal node servers? Is it possible for me to have my terminal node that is configured as an application server and talk to the Hub node which is the database?

  In addition, how the terminal node communicates with the Hub node? Thanks to a private interconnect? or through something else?

  I'm sorry that I couldn't quite find the documentation for allowing me to understand these two things.

• How to set programmatically the current node in a tree view of the ADF.

  Hello
  

  I'm trying to understand how to set programmatically the current node in a tree view of the ADF.

  My use case example is quite simple; If we take the sample application ADF Summit where under Management Summit, we have a tree view on the left with a list of high level of the country which in turn contain a subset of customers; then, in the right pane, we the customer detail information.

  What I'm trying to achieve is a solution by which I can add a new customer, commit and then to the tree show the client newly created as the currently selected entry.

  I use a pop-up dialog box to create my new entry of the customer and everything works well in this area, and my newly created folder is saved in the database.

  I know how to force the tree to cool off, but what I can't understand is how to do so, it highlights the newly created folder.

  Any help would be much appreciated.

• Understand the RDM?

  Hello

  The file system of the RDM depand of your guest operating system disk, view what you not normal a vmdk, all of the volume of your disk file is normal view your VM and is formatted by it.

• No idea how to loop and add the value to the attribute of the xml node?

  I work on a lot of flattening of project using a watched folder.

  I have a process parent to locate the directory and call a sub-process to flatten PDF files.

  I want to write the directory failed to XML.

  If there are several directory failed locations and if I want to add it to the node, he doesn't let me do.

  If I set the Xpath location like/process_data/outputXML/flattenDirectoryRequestMessage/failureFileLocation[x]/@path it gives me invalid character exception. I use 'x' for looping and incrementing.

  If I do not use the [x]. The directory is overwritten.

  No idea how loop and add all the directories failed to attribute of the xml node?

  I understand that you can not browse the xml code to assign the value at each node. Rather you can assign only one time to the node.

  I realized that it is not possible to do it this way. Then concatenate it as strings, and then attach to the xml once.

• 11 GR 2 RAC - Database Control - agent system of is not the second node

  I have a new system of the RAC node 2 11 GR 2 RHEL5 64 bit - it's a testbed at the moment. I installed Database Control because at the moment I don't have a separate grid control server available for this configuration. After you run DBCA, control of the database has started very well, and I could connect to the console and see the two available nodes. On a subsequent restart of the two nodes, I can start the dbconsole leave the first node, but the agent does not start on the second node. My understanding is that spear the dbconsole of node 1 should start the agents on both nodes. Is this correct? I don't know why the agent is not running or implementation on the second node. How can I start it? GC, I could do emctl start the agent, but apparently for the control of the database, this isn't an option.

  I can't see what follows from sysman/log/emagent_perl.trc on the first node:
  

  ties line no. 75
  maxRowCount.pl: Tue Apr 27 16:49:19 2010: ERROR:  Max Count Value not set properly in file /u01/app/oracle/product/11.2.0/db_1/sysman/config/esa/database.proper
  ties line no. 77

  I admit that I am more familiar with GC than DC, although not at all an expert. Any ideas?

  You must leave dbconsole time node. from the dbconsole will start the agent, there is no agent seprate for dbconsole
