• String to number list

  I have separate numbers by- and fate as string. I need numbers in select statements as a list of numbers.

  Can someone please help me to get this done?

  Example of a string: "7001-5001-8001.

• Only allow the string to the list

  Hello
  
  I have an ArrayList.

  ArrayList as = new ArrayList();

  Now, I want to let only the string to add in this list of tables how can I achieve this? Don't want to use generic.
  
  Please guide.

  I was asked to do not use generic.

  In example you saw generics. It is clearly said if you don't want to use generic drugs, and then use the instanceof keyword.

  I want that list allows me only to add the string if I add another object, then it should throw an error.

  Exactly, I give an idea how to use instanceof and allow that string in the arraylist objects.

  If not clear, please go through the below program:

• Retrieves a string not in a particular model of number

  Hi all
  
  I want to extract a string for example numbers. 100 to 200 or 1 to 10
  Here, a number may start from any number to a number any and there may be decimal numbers also or it can also be like 100-200. I'm stuck on this.
  
  I had a link too
  
  Retrieves the number of string value
  
  but it shows that extraction of a chain of particular model
  
  Please help me with this.

  Hello

  Sorry, my mistake. Until you have validated the sample data, I didn't test it.
  In the 2nd argument REGEXP_SUBSTR, all the g-d must have a------right in front of them. I left aside the \ before the 2nd.
  Try this:

  SELECT  REGEXP_SUBSTR ( code
                  , '[+-]?((\d+\.?\d*)|(\.d+))'
  --                          ^
  --                                ^
  --                        need \ here
  

  "\d" (with a backslash) means a number, that is identical to ' [[: digit:]] "or"[0-9]".
  has ' (without a backslash) has no particular meaning; It's just the letter small d.

• Comparison of a string with a list value

  I have a string that needs to compare it with a list of properties.
  
  For example: I need to check the 2 H chain exists or not, in a property called Testproplist. Testproplist is a property with a list of all possible values. Test proplist values A1, A2, A3, A4, H3, H5, 2 H.
  
  Can anyone suggest me how to check this?
  
  Thank you

• The list of functions: how to remove similar values/strings in a list

  Hello
  
  I'm stuck with the following: I created several lists and they won't stay to show similar values or strings.
  e.g. my list resembles
  93,97,101,104,105,107,110,111,113,93,111
  each of the 93 and 111 values occur twice in this list. What function (or something?) deletes these two values, even if the list looks like
  93,97,101,104,105,107,110,111,113?
  
  I would like to do as well with a list containing the names. e.g.
  Tom Jones, kathy winter, daryll hana, steven jobs, hillary Hill, joshua fall, hillary Hill
  where hill hillary occurs twice. should look like to my list
  kathy winter, daryll hana, steven jobs, jones Tom, hillary Hill, joshua graves
  
  Thank you so much for a short solution!

  One trick is to use the fact that Coldfusion will automatically replace the keys in a struct, avoiding duplicates.

• Need to retrieve the string after the 2nd comma.

  The input string: "CN = Beard\, of Tracy, OU = operations, OR = HPUsers, DC = HealthPartners, DC = org"

• How to use a list of strings as a parameter of data service

  Hello.
  
  I need to create a service that receives a list of string as parameter. I read the thread list of values as param - is possible to bring down the query? but I was unable to make it work.
  
  In the my namespace, I defined an element:
  
  < xs: element name = "keyList" >
  < xs:simpleType >
  < xs:list itemType = "XS: String" / >
  < / xs:simpleType >
  < / xs: element >
  
  In my dataservice, I stated the following function:
  
  declare function tns:list ($keyList as element (bt: keyList)) as {element(bt:employee) *}
  
  for $key in $keyList
  for $employee in emp:EMPLOYEES()
  where (fn:upper - eq fn:upper-case(fn:string($key))) case($employee/STR_KEY)
  return
  < bt: employee >
  < bt: name > {fn:data($employee/STR_NAME)} < / bt: name >}
  < / bt: employee >
  };
  
  When I test this situation, the generated SQL code considers that all the keys as the only parameter:
  (...)
  WHERE (UPPER (t1." STR_NAME") =?)
  (...)
  
  So, if I try a string of a list, it works:
  (...)
  WHERE (UPPER (t1." THE STR_NAME") ="STRING1")
  (...)
  
  But with two or more strings...
  (...)
  WHERE (UPPER (t1." THE STR_NAME") ="WORD1 WORD2")
  (...)
  
  What I am doing wrong?
  
  Also, on the wire, I mentioned, I would like to know how I could make the reference "for $paramString in $paramStrings / AN_ELEMENT ' using my code.
  
  Best regards and thanks for your time!

  My answer in list of values as param - is possible to bring down the query? has been

  I think you want:

  for $paramString in $paramStrings / AN_ELEMENT

  and you have:

  for $key in $keyList

  $keyList is a single element that contains a complete list, so $key is the only element that contains a complete list. And that is why it does not work for you.

  Yourself and the other poster are doing more complicated things they should be. You can simply use the following (you need not specify a child of $keyList here). The ' * ' after XS: String means minOccurs = 0 maxOccurs = unlimited.

  declare function tns:list($keyList_as_xs:string*)...

  for $key in $keyList

• TestStand 2012 Newbee question: How do I pass a string to a VI to TestStand to control the flow of sequence?

  I want to use a drop-down list box (or a similar control) in a VI to select from a list of strings to direct execution in TestStand.

  • How connect the channel selected in the combo box at the output of the VI Terminal so I can see it in TestStand?
  
  
  • What should I use as 'value' in the parameter module TestStand to retrieve the result of that VI?

  I tried "wiring" the result of the drop-down list box directly to a terminal of output without success.

  I tried "wiring" the exit from the drop-down list box to a wire string variable then this variable to an output without success Terminal.

  (see attached files)

  Can someone give me an example of a VI that allows you to select from a list of strings: {'Bob', 'Mary', 'Bill', 'Jennifer',...} using a

  (or similar) drop-down list box control and routing of the string selected to the output terminal?

  Also, how to reference this (result) setting within TestStand?

  It is a simple task and there can be only one solution TestStand, I'm looking for a simple direct execution sequence by the operator to select a string in a list.

  I studied this problem, but could not find instances of the digital comparisons or string canned and did not find a generic model that would return a string to a VI to TestStand result.

  Thank you for suffering through this fundamental question.

  Marco beat me but here is my interpretation. TS 2010, LV 2011

  Also, look at the example of demo which comes with TestStand: C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 2010 SP1\Examples\Demo\LabVIEW\Computer Test of the motherboard

  Demonstration should be a version of what you want.

• Pass data to list to the page navigation item

  Hey all, been a problem trying to transmit data to a list item selected to a page which I am pushing by a NavigationPane.

  My list contains a lot of elements, each with a property that contains a url. When an item is selected, I need a new display to be pushed with a component WebView that inherit from that url and display the Web page.

  Here's my list qml file:

  import bb.cascades 1.0
  
  TabbedPane {
      showTabsOnActionBar: true
      Tab {
          title: qsTr("List")
          NavigationPane {
              id: navigationPane
              Page {
                  property string selectedItemUrl
                  id: tab1
                  Container {
                      layout: DockLayout {
                      }
                      //topPadding: 70
                      ListView {
                          objectName: "list"
                          listItemComponents: [
                              ListItemComponent {

                                  FeedListItem {
                                  }
                              }
                          ]
                          onTriggered: {
                              var selectedItem = dataModel.data(indexPath); //get data of selected item
                              var page = webView.createObject();
                              page.webUrl = selectedItem.permalink;
                              navigationPane.push(page);
  
                          }
                          attachedObjects: ComponentDefinition {
                              id: webView
                              source: "PostWebView.qml"
                          }
                      }
                      ActivityIndicator {
                          objectName: "indicator"
                          verticalAlignment: VerticalAlignment.Center
                          horizontalAlignment: HorizontalAlignment.Center
                          preferredWidth: 200
                          preferredHeight: 200
                      }
                  }
              }
          }
      }
  

  And here is my file qml for the page with the Web view:

  import bb.cascades 1.0
  
  Page {
      property string webUrl
          ScrollView {
               scrollViewProperties.pinchToZoomEnabled: true
               scrollViewProperties.scrollMode: ScrollMode.Both
               Container {
                   layout: StackLayout {
               }
              WebView {
                  id: webView
                  url: webUrl
              }
          }
      }
  }
  

  As you can see I have retrieve the data of the list item selected, create the view, assign a string property in the Web view page to the url property of the data item and push the new view.

  What exactly am I doing wrong? Any help would be appreciated, thanks!

  Thanks for the tip about debugging right through it.

  I found and corrected a small error in my code that does the job, but I also noticed something.

  I noticed that the WebView component has been initialized before I had the chance to assign a value to the property in the chain of the WebView qml file. After executing this line.

  "var page = webView. createObject ();"

  It seemed as if the WebView had already been created, and I had not had the opportunity to give my url.

  But this line then runs

  "page.webUrl = selectedItem.data.permalink;

  and it seemed to reset the component WebView so that he could take my value.

  Hard to explain, but works in all cases.

  Thank you!

• Array of strings JPA

  Hi all.
  
  Is just a quick question on JPA - possible to retrieve a single column of type varchar2 from a table as a table or a list of strings using JPA?
  
  As a brief example, I would like to get the following code would ideally be a String [], or a List < String >.
  

      ...
      EntityManager em = Persistence.createEntityManagerFactory("MyPersistenceUnit").createEntityManager( );
      
      List result;
      try
      {
          String q = "select distinct mt.textColumn from MyTable mt";
          Query query = em.createNativeQuery(q);
          result = query.getResultList();
      }
      ...

  What happens in practice is however a list of vectors, where each vector contains a single string. A most inconvenient result. I suppose another option would be to define an entity class with a member of the chain, but it isn't really better.
  
  Thank you!
  
  Mac.

  I believe that this issue has been raised and has been set for the EclipseLink, version 1.1, which will be available in the next version of Oracle TopLink. Here are two test scenarios that illustrate how you will get a single value or an Object [].

  @Test
  public void readStringUsingNativeQuery() throws Exception {
       EntityManager em = getEntityManager();
  
       List results = em.createNativeQuery("SELECT F_NAME FROM EMPLOYEE").getResultList();
  
       for (String name : results) {
            System.out.println("> " + name);
       }
  }
  
  @Test
  public void readStringsUsingNativeQuery() throws Exception {
       EntityManager em = getEntityManager();
  
       List results = em.createNativeQuery("SELECT F_NAME, L_NAME FROM EMPLOYEE").getResultList();
  
       for (Object[] names : results) {
            System.out.println("> " + names[1] + ", " + names[0]);
       }
  }

• CNVString - send strings of a PXI chassis by ethernet to an application of labWindows on another computer

  I have a PXI chassis with a PXI-8101 controller. It is equipped with a system of operating in real time. I connect to it on a PC with a Windows operating system. I am trying to send my PXI system variable length string messages to my PC.

  On the PC, I have a LabWindows application that allows you to send and receive data with the PXI system. I'm trying to send the PXI system error messages to the PC on ethernet. I am able to send digital data between them, but not the string messages. The PXI software meets the CNVCreateArrayDataValue() function call and not to her, but never returns. There only have this problem when the CNVDataType parameter is CNVString; When I change the CNVDataType to CNVBool it doesn't have this problem. I'm new on this time real PXI so would appreciate the help. Here is the code on my PXI system that sends these text messages.

  At the beginning of the RTMain, I create the writer

  CNVCreateBufferedWriter ("\\\localhost\\system\\" REG_CAL_ERROR_STRING, 0, 0, 0, 64, 5000, 0, & gErrorPublisher);

  Then I call a function with a string in the list of parameters:

  void SendRT_ErrorMessage (char * message)

  {

  Data CNVData = 0;

  int error;

  error_str char [256];

  int i;

  char out_str [ERROR_STRN_SIZE * 4];

  strcpy (out_str, message);

  size_t arrayDims = ERROR_STRN_SIZE;

  arrayDims = strlen (message) + 1;

  error = CNVCreateArrayDataValue (& data, CNVString, out_str, 1, & arrayDims);

  If (error<>

  {

  strncpy (error_str, CNVGetErrorDescription (error), 256);

  }

  CNVPutDataInBuffer (gErrorPublisher, data, 1000);

  CNVSetArrayDataValue (data, CNVString, out_str, 1, & arrayDims);

  CNVPutDataInBuffer (gErrorPublisher, data, 1000);

  CNVDisposeData (data);

  }

  Change this:

  public static void CVICALLBACK ErrorMessageCallback(void * handle, CNVData data, void * callbackData)
  
  {
  
   char message [ERROR_STRN_SIZE];
  
  CNVGetScalarDataValue (data, CNVString, & message);
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, "got something\n");
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, message);
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, "\n");
  CNVDisposeData (data);
  }

  To do this:

  public static void CVICALLBACK ErrorMessageCallback(void * handle, CNVData data, void * callbackData)
  
  {
  
   char * message;
  
  CNVGetScalarDataValue (data, CNVString, & message);
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, "got something\n");
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, message);
  
   (void) SetCtrlVal (panelHandle, PANEL_TEXTBOX_DEBUG_MSG, "\n");
  CNVDisposeData (data);
  }

  You also need to add CNVFreeMemory to free the memory allocated for the string.

• Why flatten data chain not getting past all about TestStand via a local variable of the string?

  I tried to go around a series of data in TestStand as a string using "flattened chain" of LabVIEW. When I create a local variable in TestStand of type 'string' and try to write the cluster flattened at this that he simply not transmitted. If I convert the string flat binary table and then pass it around, I can recover all the data very well.

  Is there something I'm missing here?

  I've attached an example Teststand sequence that illustrates this problem. If you run this sequence that the 1st test will fail, which is the attempt to simply pass the flattened string data structure and the 2nd test will pass as it is the binary table that I generated from the flattened string.

  Thank you

  crossrulz is correct.  The Null character affects how TestStand handles the string.  You will need to specify the string to a binary string in the list of settings both the VI.  TestStand then encodes the stringso it can prevent the loss of data.

  If you need work on the binary string in TestStand, you will need to convert it to an array of raw data with PropertyObject.GetValBinary.
