  How to use String?  VIsa give him a few words, how to be part of this expression?  I want to cut the words in many parts. And throw a few words I put "t.

  Hello

  Function String scheme basically retrieves a subset of the strings of a string. For example, lets say we want to extract the view of the word labview. The function will look like this:

  

  Where:

  3 corresponds to the offset, the starting position. The first character of a string is zero.

  4 is the length.

  So, basically, we act in 4 characters starting at position 3.

  Hope this helps, for LabVIEW issues I recommend you the Forum of Discussion of LabVIEW.

  Kind regards

• String.startsWith always returning true.

  Hello, I have a small issue that has been driving me nuts. I am a beginner in Java, so the problem is most likely something stupid that I monitor, so I would like another opinion.

  Basically I have a listfield I want to make it searchable. I had another problem earlier with indexOfList always returning-1, so I gave up using it. Instead, I am a loop in the listfield table and see if _seriesList [i] .startsWith (_searchField.getText ()). For some reason, it ALWAYS returns true, causing the first item in the list to be chosen as the result of the search. Here is the code:

    for(int i = 0; i < _seriesListField.getSize(); i++)    {     String temp = _searchField.getText();     System.out.println(_seriesList[i].Title);     System.out.println(temp);     if(_seriesList[i].Title.startsWith(temp));        {         System.out.println("startsWith returned TRUE");           _seriesListField.setSelectedIndex(i);         return;       } }
  

  No matter what value I give, startsWith return true. I also tried to use substring (0, temp.length () .equals (temp) instead and who also returned the value true. My console output is:

  07 - ghost<-- the="" name="" of="" the="" first="" item="" in="" the="">
  C<-- the="" value="" i="" typed="" into="" the="">

  startsWith, returned the TRUE value

  The javadoc for startsWith says he can return true if the prefix is null or if channels .of each other, see, however I see that these two are clearly false from the console output.

  I could use help to find out why this happens and fixing it, and if it turns out to be something mind-numbingly stupid and/or obvious I apologize profusely in advance.

  It is a sad, sad day for me. I had a semicolon after the if test. While the error itself is not so bad, the fact that it took me nearly an hour to discover this is painful.

• String.startsWith, method behaves like the method String.equals

  Hello
  
  I work through the assignment of the Java Servlets and JSP, and told me to use a simple iterator method and startsWith. This bit is not part of the assignment as they write it for you, but it does not work for me.
  
  Grateful for any help, I'm not cheat my assignment because it comes to Servlets and JSP, and I'm not marked on this part.
  
  Here is my results using System.out during an iteration through my loop.
  
  Green home starts with the Green House
  the Pink House does not start with the Green House
  the Blue House does not start with the Green House
  the Pink House is bigger that the Pink House does not start with the Green House
  the Green House is bigger that the Pink House does not start with the Green House
  the Green House is bigger that the Green House does not start with the Green House
  the Green House is bigger that the Red House does not start with the Green House
  the Blue House is bigger that the Pink House does not start with the Green House
  
  
  My table list is built like this: -.
  
  searchPrompts = new ArrayList < String > ();
  searchPrompts.add ("the Green House");
  searchPrompts.add ("the Blue House");
  searchPrompts.add ('pink house');
  etc.
  
  
  and my loop is less and does not compile if I throw the (String): -.
  
  int countMatches = 0;
  for (Iterator it = searchPrompts.iterator (); it.hasNext () & & countMatches < = 5 ;))
  {
  String aPrompt = (String) it.next ();
  If (searchString.StartsWith (aPrompt))
  {
  System.out.println (aPrompt + "begins by" + searchString);
  matchingPrompts.add (aPrompt);
  countMatches ++;
  }
  on the other
  {
  System.out.println (aPrompt + "does not begin by" + searchString);
  }
  }

  Your code says:

  If one starts with B, then print "B starts with a.

  Until your prints claims is put trial is not actually what is being tested.

• By the way the table of Clusters with binary strings via adapter LabVIEW

  I need to go through LabVIEW adapter table clusters containing binary strings.
  These data will be subsequently stored in the MySQL database.

  I need to force the option "Binary string" for the ValBinary element, even if my output array is empty.

  Is this possible?

  Used versions: TestStand 4.2.1 + LabVIEW 8.6.1

  Attached file: valbinary2.vi containing the clusters of test output array.

  Howdy Jean-Louis,

  My apologies, I'm not quite your question. You're right that LabVIEW does not know that a string is a binary star strong; LabVIEW, chain stores in a format of Pascal, looks like all the strands in the same way. Because TestStand stores strings in the C type format, on the other hand, the null (0x00) characters can be confusing when interpreting strings in TestStand as you learned to understand. That is of course why TestStand offers the feature to interpret strings as binary strings.

  As Sylvie refers to his post, to illustrate his point I created within TestSTand an array of the same type of data customized to store past out of your valbinary.vi of test data. Test patterns, I also edited the outputsome constant values to the cluster VI. (See the following screenshot). Note that the last string (named ValBinary) in the cluster contains a hexadecimal string with a null character that is inserted as the 3rd on-screen character (before the actual end of the string).

  

  Here is a screenshot of the created sequence file that calls the VI and then displays the number of items in the table from the VI to the user.  Note that the Locals.MyTestData table is empty before the execution of the sequence.

  

  Finally, as the execution of the sequence, I opened the Variables pane to view the contents of the Locals.MyTestData table. Here, I have confirmed that the "binary" string of LV was successfully passed in and stored by TestStand.

  

  Finally, the popup message in the second step of the sequence shows indeed a message indicating there were two elements in Locals.MyTestData.

  This sequence has been able to run successfully even without manually specifying a size of Locals.MyTestData beforehand. TestStand dynamically allocated the necessary elements to store the results of test valbinary.vi.

• use IMAQdx functions in Labview Communications System Design Suite

  Hello

  I would like to read an image and use the bytes obtained to perform certain functions. Currently, the system has Labview Communications System Design Suite (2014 SP1)

  and vision acquisition software installed. I don't know how to use IMAQdx features in labview.  Can anyone help?

  Thank you!

  I do not work with the Design Suite of Labview Communications System.

  In LAbVIEW, however, when after you install LabVIEW first, then the Vision Acquisition, you can use the example Finder locate IMAQ or IMAQdx for LabVIEW examples: in LabVIEW, select help > find examples. This will open the Finder of the example. On the "Search" page, type the keyword "IMAQ" or "IMAQdx" (depending on your device) and look at the examples that come with the Acquisition of the Vision for LabVIEW.

• Check the development of an Image with Standard of LABVIEW functions

  Hello

  I want to determine the best quality of the development of a series of color images using features standard LABVIEW, an example my images would be KING of coins in copper or similar sample 2 mm x 1 mm. I do not have the Toolbox IMAQ vision, so this will not be an option. Could someone give me an example of this or point me in the direction I must go. Is it better to check the quality of the focus on the image of color or black and white image or perhaps a representation of the intensity of the image? I heard that the gap checking type of a line of pixels in the image would give a good indication of the quality of the development by seeking the higher SD all images?

  Any help is greatly appreciated!

  Convert the image into an array to IMAQ ImageToArray.

  Extract a single line or row of the table by using the table to Index.  Assuming that your image be U8, these will be U8 values.

  Digital conversion to Double can convert the array of double values.

  Use Rotate 1-d array with an offset of 1 to turn the table.

  Subtract the table of rotation of the rotation matrix.

  Deletion of the table to delete the first element of the array.  It's the difference between the first and last items, which is not desired.

  Absolute value to convert the table of all positive values.

  Use the mean or the standard deviation to measure the development.  I usually have better results with the standard deviation, but sometimes means gives good results also.

• Whence the full featured controls the location of the button pause/repeat of the UI?

  TestStand 2012, 2012 LabVIEW, Windows 7, Full Featured UI: LabVIEW

  I'm changing the complete UI featured in response to the needs of businesses.

  I've added a new tab (operator) to show just the buttons on input control Point 1 and 2, and restart/Terminate/Pause/Resume.

  I placed these buttons on this tab and then modified the code to their location on the tab to start.

  I modified the code to set the entry Point 1 and 2 buttons where I want that they on the new tab, it works fine.

  I used a similar code to Pause/Resume, Terminate / restart on the new tab, but they keep themselves moved to the execution to the boot tab.  What is happening and how can I stop?

  Thank you in advance.

  Thank you to look at my problem, I actually found my own solution.

  I changed the code in such a way that he was stacking the buttons on top of the other and they are hiding.

  Problem solved.  I guess I'm now a step upward from the beginner because I've solved my own rookie mistake?

• LabVIEW.lib or labviewv.lib?

  Hello

  I'm writing a C++ DLL that interacts with the LabVIEW code, which uses features of LabVIEW Manager. The linked article says I should link against labviewc.lib, but there is another similar library called labview.lib

  What is the difference between them? Which should I use?

  It's labviewv.lib not labviewc.lib! Generally, you should use labviewv.lib for all new development. It handles better on the right the LabVIEW core binding when you have complex situations such as a DLL LabVIEW (screw of LabVIEW compiled into a DLL) that uses the DLL and when that LabVIEW DLL is called from a LabVIEW system which is a different version of which was used to create the DLL of LabVIEW. With labview.lib, this scenario is very likely create a chaos he is trying to link to the system LabVIEW calling instead of runtime DLL runs under.

• Where can I find the download link for Labview 7.1?

  I'm not find labview 7.1 on the site of national instruments.
  I appreciate if someone helps me with the link.

  woahhhh
  Thank you
  but I'm looking more for the evaluation version of article 7.1. In this connection, I have to activate it.

  No, you don't.  LabVIEW 7.1 was the latest LabVIEW version that does not require an activation method.  Heck it does not even require a serial number.  It will keep nagging you saying something like 'if I noticed I don't have a serial number you want to enter a' and if you say that it's just like 'it's cool maybe next time bro

  Last secret.  LabVIEW 7.1 was also the last version that you could put in a random series of and as long as it was in the right format it would be happy and unlock all the features of LabVIEW.  It goes back again to the fact that there is no activation and it no way of knowing if the series you entered was one that you own it or not.

• Operate devices cDAQ in Labview 8.0

  Can you run cDAQ features in Labview 8.0 using the latest version of DAQmx Labview 8.0-supported? I bought a cDAQ-9174 and some modules, but the included driver disk (DAQmx 9.5) is not supported in 8.0 LV. Is it possible to install drivers without installing DAQmx 9.5 so I can use the DAQ with DAQmx 8.X Wizard? Thank you.

  According to this list, the minimum version of LabVIEW for the 9174 is 8.2.1 and the minimum DAQmx version is 9.0.2. I expect the first of these two to be the main issue here.

• Launch a LabVIEW VI to the background of CVI

  Not sure if this is better posted in the LabVIEW or CVI forum...

  I need to start a LabVIEW VI "in the background" of the CVI.  In other words, I need to call a LabVIEW VI (which is embedded in a DLL) of CVI and have the function call immediately, while the VI called end of running in the background.

  I've had success making this kind of asynchronous call of in LabVIEW using an asynchronous start node name.  This works because it is supposed to: the node of the asynchronous call ends the execution immediately, while the called VI runs in the background.

  The problem arises when I integrate this into a DLL and call from the CVI.  If I build the DLL with active debugging and then walk through the code, stopping the code just after the asynchronous call, the background VI runs correctly.  But if I run all this full speed, the asynchronous VI does not run.

  I guess that the call of the DLL returning before the asynchronous VI can finish, the asynchronous VI is killed during the call to the DLL returns.  Obviously, I need the background / asynchronous VI ends once control is returned to the CVI code.  Am I doing this wrong?  Is there a better way?

  My code is highly integrated and probably not useful to publish.  If this could help write an example isolated post, I'll do that, but only if others cannot identify a better/different approach.

  Thanks in advance,

  Joe

  Hey JoeDG,

  Yes, as Evan mentioned in the thread you referenced, it's a feature of LabVIEW. As he says, for the ongoing enforcement there must be at least one open front. While I understand that this causes problems for the screws that are run without front panel, it seems that the workaround that you put in place is the best way to go. I apologize that you had to take an indirect route to achieve your final goal, but I'm happy that things are facing up and running for you now.

  Best,

• Transfer of files of arduino for Labview

  Hey.

  I do my b.a. in Labview using an Arduino 2560. The arduino controls a temperature probe, with 16 pixels.
  I made the connection with the microcontroller of the sensor, using I2C - bus. Arduino MI send via USB as a package of 16 bytes, that contains the temperature measurement.
  I have a problem with how I should read the transfer of files in Labview string text to table.

  I downloaded the Labview interface for arduino and have connection with Labview and arduino.

  I have searched the Labview interface for arduino modules but can't seam to find a drive bytes.

  The end result would be a graph of intensity which show temperature mearsurement.

• Converts a string (float single precision) in decimal

  Hello

  I use reading series base and write vi to communicate with a device.  The answer I receive (shown in hexadecimal format) is 4606 8D3B, which from what I understand (this discussion: http://forums.ni.com/t5/LabVIEW/string-to-number-conversion-a-very-interesting-observation/m-p/32170... ) the data is not actually hexadecimal but rather binary and appears just hex for the user.

  My camera manual says that this information is "Float - 4-byte ANSII standard simple precision, low to high" and I'm trying to convert this string to a decimal value.  (it should be 0.004 or e-3 xx 4)  So far I've written a program that separates the bytes in a table of 4 bytes, each binary converts and then separate all binary bits and try to group return the binary bits in the exponent and the mantissa to calculate the value, but it seems rather convoluted and I hope that there is a more simple function in that all this is done automatically.  Also, since the answer is low to high, I understand that I must first return the number of 3B8D 0646 make high to low, but I think I did that already, it's just the conversion that I do not know how.

  Any help would be appreciated, thanks

• run labview applications in web applications

  It's just a general request.

  I have a large collection of labview applications.  I would like to "web-ize" some of them, i.e. operate the façade in a browser and the logic of block diagram in a server.  There are many articles on the web site OR to this topic, but I find them confusing and free often contradictory.  Many of the items are old enough and can be updated.

  I have the following specific questions:

  1. I'm under Labview 7.1 on a Windows XP computer.  Do all the features I need exists in 7.1 or should I update?

  2. is it possible to do simply through the configuration options, or do I have to change the code or restructure demand?

  3. someone can tell me an article or a book with current step by step instructions to do what I want to do?

  4. is there anything that I would be the features of labview wary, specific that are problematic?  Performance issues?  etc.

  Just as I feared, but thank you very much for the clear answers and helpful tips.

  David
