Features of LabView string StartsWith as in c#?

Hi all

in c# (.NET) there is a good class: String

There, it is possible for example to get information, if the string startswith one substring special.

Is that what this possibility in LabView? Y at - it these LabView vi, which offers this feature? (Excerpts)?

So I ask you:

I want to create a switch/case (structure-case) block in labview for this code:

If (String.StartsWith ("XYZ")) step in case1

another step if (string.startswith ("DEF")) in CAS2

...

BTW:

It would be great if someone could create polymorphic VI with these functions:

So I ask you:

I want to create a switch/case (structure-case) block in labview for this code:

This can be done already with the structure of the case, you can make simple analysis in the case selector, which takes a string as input.

Type in the case of the first case "XYZ".... "XYZ".

Enter the next case "DEF".... "DEF ~".

Next is the empty string, the default value.

How does this work:

The "XYZ...". "XYZ ~ ' matches all strings that begin with XYZ and any ascii value after the ~ is the highest value printable 7-bit ascii for that catches all the other characters.

Option 2 is parse (there is expression reg very good vi in the channel palette) the string and create if a corresponding to the value of the integer can habdle unique integers in the structure of the case.

There are so many ways to do it without a wrapper for the string .net class, I have provided some quick methods

  • 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.

    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.

    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): -.

    for (Iterator it = searchPrompts.iterator (); it.hasNext () & & countMatches < = 5 ;))

  • 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.

    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.

    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.

  • 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.

  • 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
