Node FB: Initialize on first convocation

• Range of the program adjust the lag on first convocation

  Hi, I just noticed this discrepancy, but it turns out that he's always been there.

  Basically, I have 2 buttons on the screen - "Ave" and "Std".  The default view is Ave and when I click the Std button, RangeY is adjusted according the current selection button programmatically.  For some reason any lag on the first Std click there and then it's all good go back between Ave and Std.

  Thank you

  Private beach m_rangeY;
  
  Audience RangeY
  
  {
  
      get {return m_rangeY ;}
  
      Set {m_rangeY = value; OnPropertyChanged ("RangeY"); }
  
  }

  Range = ShowAve? Ave.RangeY: Std.RangeY;
  
  If the beach was not established then autotuning
  If (beach. Minimum == 0 & range. Maximum == 0)
  {
       RangeYAdjuster = RangeAdjuster.FitExactly;
  }
  on the other
  {
       RangeYAdjuster = RangeAdjuster.None;
       RangeY = range; If I put this comment out line, there is no lag
  }

  I use Measurement Studio 2015 in Visual Studio 2013.

  These lines in the output window indicates that the graph is data reception/rendering for the first time when you click on Std.

  To exclude a control problem, another change, you can try is to move the data source assignment occurs after that executed the links:

  Dispatcher.BeginInvoke( new Action( delegate {
        GraphMain.DataSource = ShowAve ? GetArrayAve( ) : GetArrayStd( ); // MY CHANGE
    } ), DispatcherPriority.DataBind - 1 );

• make a Subvi do something on first convocation

  Hello

  I have a Subvi I made and I want her to do something the first time that it is called as long as the delivery of the program, it should do something else.  Right now I have a "First Call" function connected to it, and they spend a tru the first time my Subvi is ecounterd and a flase each other times... it works... but I was wondering if there is a way to get rid of it within the Subvi itself?

  Thank you!

  Why you do not place the 'first call?"primitive within the Subvi?

• Videos won't load is not properly on first convocation... desperate online

  Problem weird here, people.  I have a web page created on board animate that reads videos (4) at the same time and it works very well by using "Preview in the browser."  It does NOT correctly load the time _first_, it is called from the Web site.  It - everything except videos - charge that partially the first time that a not in browser's cache (Firefox, Opera, Chrome, Safari) trying to load the page.  However, after trying to load the page from that first time, if you go immediately to any other Web site and then come back to my site to load the page, the page loads correctly.  It kills me.  I'm guessing that this behavior will be immediately recognized by someone who can tell me a solution.

  To show this behavior:

  1) go to the http://www.lightisrising.com

  Loads a partial page (without animation in the upper left corner, bottom left, right, and lower right cells).

  2) go to another website, such as Adobe.com

  (3) back to www.lightisrising.com, and the page load and play the videos properly.

  Of course, I need the page to load correctly the FIRST time someone visits it.

  Thanks in advance for any help. Very much appreciated.

  There seems to be a bug html5 video. with several auto-play videos, it will display: none; the first time it loads.

  I'm still working on edgehero 0.3 and I fixed it already, simply by adding some css display: block; for the video tag.

  I hope that helps you fix.

• ListFieldCallBack DrawListRow will not display background on first convocation

  I have been racking my head for a few hours trying to get this working.  The bottom of my custom list field updates only when it is updated, not on initial load.  I have a custom listfield (modification of the listfield example).  From my main screen, I opened a 2nd screen, load the list and display the data.  It works without error.

  My problem is that in the drawListRow of ListFieldCallback, I have:

  public void drawListRow(ListField listfield, Graphics g, int index, int y, int width) {   EventTableList tableListField = (EventTableList) listfield; Background bkg = BackgroundFactory.createSolidBackground(Color.CHOCOLATE);  tableListField.setBackground(bkg);              TableRowManager rowManager = tableListField._rows[index];                       rowManager.drawRow(g, 0, y, width, tableListField.getRowHeight());              }
  

  The text of each line, but the background is only updated when I

  (a) highlight the line

  (b) add or delete a folder (which calls the method of painting even I call from my listfield constructor).

  * I have a myPaint method in the class listfield invalidate calls, my constructor is called and it is also called when a record is added/removed from the list.

  Any thoughts on what could happen?

  I use the 4.6 component package.

  Thanks in advance.

  set the background when you create the listfield.

• BlackBerry Smartphones phone sounds do not on first convocation

  Scenario: My phone is on my desktop not connected not sitting with the black screen, if someone calls the screen lights up and I see the symbal of "thought" in the middle of the screen. But until him phone 'wakes up' my voicemail picked up, the phone does not ring. If they call right back or someone else calls it in the next few minutes fine rings. Miss me several calls a day with the phone, just in front of me on in my uniform pocket. Someone knows how to fix this?

  Thank you

• Feedback node initializer ignored?

  Hello

  I have a feedback node sitting in a loop, the number of iterations is determined by a table of entry. The same input array is connected to a terminal of the initializer of the Feedback node.  The delay of feedback node is equal to 3 and still output the node contains only the first value in the array for the first 3 iterations. It is easier to show than describe them.

  

  So I expect the output array to hold the values 3,1,0,0,1,2 and yet it actually contains 3,3,3,0,1,2

  If I have the scalar value 99 wiring to the initializer then I get the EXPECTED 99,99,99,0,1,2

  What Miss me?

  It comes to LabVIEW 2011 for MAC OS X

  To develop the Swatts answer a little more.  You are in fact only during the initialization of the feedback with a single element node because you have the array of automatic indexing in the tunnel of the loop.

  If you powered the table in its entirety in the loop For and the initializer of terminal, the way you would expect it would have worked.

  

• 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.

• set the configuration of appeal vi for node reference vi call

  As noted in the title someone knows how to set the configuration of appeal vi (load with the appellants, charging for each call, load and store on first convocation) for a vi dynamically loaded via call by reference node?

  Thank you.

  CBR is irrelevant in the present case, since he already receives a VI reference.

  If you use the primitive opening VI refers to open this reference, then the VI will be charged the first time you call the primitive.

  If the VI leaves no memory (and you do not configure it on the way home), subsequent calls to the prim OVR returns the reference to the first VI you have opened. This is equivalent to the load and keep it.

  If you close and reopen the VI reference, it is equivalent to recharge.

  If you use a static reference to the VI, it is equivalent to the load with the appellants.

  Personally, I have all my default subVIs charge with the appellants.

• Formula node error: lack the right parenthesis

  Community salvation OR,.

  I work with the structure of nodes formula for the first time and I came across this error that I can't fix.

  

  He says he finds a character #, but the strange thing is that there is no character. Is there someone who can help me with this one please?

  Kind regards

  Thomas Ruts

  On your first long form you are missing a closing parenthesis.  It is in the last half of the formula.  You have two left parenthesis, but only a right.

• LabVIEW 8.5 problems using strings with MATLAB Script node

  I am having some problems that seem to be a bug that I can not understand how to solve using strings in the MATLAB script node.

  I have two subVIs that make some calculations and both include a variable called "errortext" is a string. The two subVIs do their calculations using the MATLAB script node, so all the outputs are defined in the script node.

  The first sub - VI outputs that string and a number. The string is sent to an indicator on the front panel. The number is sent to the second Subvi which performs some calculations more and then returns another string of the same name to an indicator on the front panel. This second string is different from the first (error different two messages should appear).

  I did have problems with this in the past until this morning. This morning, it seems that two of these channels are now somehow mystically connected to each other. The second string repeat that what the first channel said despite the fact that the first string is not be linked to the Subvi where lives the second string. The only link between the two is a calculated value of double which went from #1 to the Subvi #2 Subvi.

  I tried many things: I tried to rename the strings so that they do not have the same name. Initially, he would not let me and gave me an error saying that the renowned string was a undefined variable (which is ridiculous). After removing and replacing things, I finally managed to do so I would change the name, but now it displays nothing at all and even more I think it might still display a completely different another string in my code!

  I also tried to remove the channel indicator and replace it. Yet once, it wouldn't let me initially. I would like to highlight, press DELETE and nothing. Finally after replacing all the subVIs with them, I was able to remove the flags, but this did not help the problem.

  Any idea for these problems pecular is greatly appreciated!

  I totally understand what you did, you were talking about variables in your fist post, and it was not clear if you were referring to a variable you have defined in the Matlab code, or you try to call a variable indicator/control, where is often seen on this forum (and who isn't). That said, the crux of The Matlab Script communicates with Matlab via ActiveX, and when you use a command window opens small. This is the workspace of Matlab environment. A variable that you define in a Matlab Script node will be visible in the other, even if it's in another VI (see attached for an example, figure). This is because the script nodes are running in the same environment space. It seems to me that if this is what is happening.

• XML file - child nodes table

  Just starting to learn more about XML.

  I have a simple XML I created which is

  
  
  
  Ambient
  
  
  panel1
  
  
  panel2
  
  
  panel3
  
  
  

  Using the XML property - child results node table of nodes in a table of 9 elements:

  #text
  Probe
  #text
  Probe
  #text
  Probe
  #text
  Probe
  #text
  

  My question is what are all the #text that are there?  Should the child nodes be not just the probes?

  It seems to me you may be heading down a dark path.  Instead of using the "table of nodes child" and fighting through the unnecessary complications and text nodes, let me suggest you look at XPath and using "get all matched Nodes.vi ' or 'Get first match Node.vi' to get the items.  XPath allows parsing XML child's play.

  For example:

  

  Of course, I hope that you use XP does not mean you use LV8.6 or earlier since the XPath screws are new to LV9.

  If you use LV8.6 or earlier, I suggest looking in the .NET functions to implement XPath.  Once you get the hang of it, it still beats the attempt to parse XML the old-fashioned way.

  As for the editor, I generate very few XML files by hand, for the most part I bring other programs and analyse them in LV again, XPath adjusts the rough edges.

• Research within an XML node

  I'm trying to use the XML parser, in LabVIEW to read a custom XML file.  Basically I have several SubTest tags, each of which can or not contain multiple tags.  I want to search in each of these subtest tags to see if it contains each of the tags am interested and write in a cluster if it exists, or write a default value if it does not exist.

  I try to use get them all nodes matching and get first node in correspondence to achieve, but it doesn't seem to work.

  I use get all nodes matching for search tags subtest then pass each of these nodes in get first node corresponds to search tags in the node for each number that I'm interested.

  The problem is that first node to match returns the first match for the entire document each time, NOT the node I'm going in.

  I have attached a simplified VI that illustrates the problem.  Wrong documentation for first node of correspondence, or I do something wrong?  Thank you.

  Note: Using XML is saved in 2012 and Help_11 XML is saved for 2011

  Your search for price won't.

  As you're already gave a link to the book node, then you have not need search again from the top node.

  Replace your XPath 2 of "/ bookstore/book/price" only "of prices.

• Visible property node tab Page work does not correctly

  I do a vi in which we have a tab with 6 pages control and to move from one page to the next there is control of ring with option for each page to page 1 (page 1 is the default value), at the same time only a single page is visible, so that we can move only through the control of the present ring on page 1 and return to page 1 of all the other pages there is button "return" on all other 5 pages, everything works well for 5 pages, but when after going to page 6 and then if I press return button instead of going back to page 1 program crashes and one more thing I've noticed is after that judgment of the program on page 6 becomes the default page (which is page 1) I know not why it is past.

  I enclose the snippet of code that runs when I press go button "back".

  one more thing I get here is when I checked the program through the execution of the step, the last property node (page6) that runs first, after that it goes to the first node in property, then he goes in order, this also I want how is what is happening.

  It would do the same thing as your code?

  

• The XY graph Plot.LineWidth Property node problem

  Hello!

  I have a loop, where I repeatedly putting curves in a XY Chart. In the first iteration of the loop, after the first corner appears on the graph (I send data from the graphical indicator), I use a Plot.LineWidth Property node to align the thicker. However, in the next iteration, when the second plotted curve appears on the graph, and the property node is pulled again, the second curve remains thin. I guess what I've done wrong, that this property node defines only the first curve? How can I set the width of the line of all the curves of the XY graph on the same value? When I directly on the properties of XY graph, I can set the width of the curve, but only one by one...

  Suggestions how set the widths of the ground on a specific chart XY?

  Thank you!

  If it is a multiplot XY, you must set each plots properties by using the property activeplot (index of the new lot), then by setting the thickness.
