  I can extract a value for FULL-TIME 1 or 2, is not a problem.
  However, how can I go on the selection of a value of an attribute below FULL-TIME X, where X is the maximum value of FULL-TIME in any node in the XML document?
  
  I tried to the last node corresponding to my way, but it is not always the case that the FULL-TIME max will correspond to this scenario.
  
  Any help would be greatly appreciated!
  
  Thank you very much, Pete

• Is there an external link to use to restore Windows XP Home to original values? I can only use safe mode at the moment that my computer shuts down automatically (with blue screen)

  Running Windows XP home SP3. eMachines T6528 AMD Athlon 64 3500 + processor, nvidia GeForce 6100 GPU
  I downloaded and executed a double file Finder and SEVERAL files deleted by mistake.

  According to these instructions, you are not supposed to do that! Look at them again. They are on p. 137 (or p. 145). (P. 137, printed on the bottom or the p. 145 of the .pdf file!)

  Remove all the drives and physically disconnect all USB and network connections first!

  Then either start as you normally would (if you can) and select:

  Start | All programs | System recovery | System recovery

  and then click Yes.

  Or if you are unable to start up as usual, you will need to press F11 at the beginning - almost immediately after the ignition of the PC.

  THEN, when you are prompted to, you can insert the disc. :-)

• Access the DataSocket only using nids.dll

  Hello
  I have the task to communicate to a program, written in LabView, while communicating data hit, using only the INIDSCtl and ICWData of nids.dll interfaces. Communication in the sense that I send data to the program LabView works, but I have problems receiving data. The data that are sent are a set of 4 floating values (32 bit floatingpoint). I can see in the diagnoses of Server Socket given that there really are packets sent, but I can't receive these data.
  I'm this programming in C++ using MS Visual Studio 6.0. I don't have any other tools (such as Measurement Studio).

  The labour code to send only an integer value is simple 16 bit (I removed all control error for shorter code)

  #import "C:\windows\system32\nids.dll" raw_interfaces_only, no_namespace, named_guids
  ...
  HRESULT hr = g_pNIDSCtl.CreateInstance("CWDSLib.CWDataSocket");
  ...
  ComBSTR bstrURL (_T ("dstp://localhost/emmenu_to_ts"));

  HR = g_pNIDSCtl-> put_URL (bstrURL (bstr_t));
  HR = g_pNIDSCtl-> put_AccessMode (cwdsWrite);

  b short;
  HR = g_pNIDSCtl-> SyncConnect (30000, & b);

  ICWData * pData = NULL;
  HR = g_pNIDSCtl-> get_Data (& pData);

  CComVariant varStart (short) 1;
  HR = pData-> put_Value (varStart);
  pData = NULL;

  HR = g_pNIDSCtl-> Update();

  HR = g_pNIDSCtl-> Disconnect();

  However, the code to retrieve the data that does not work is as follows

  CComBSTR BstrURL (_T ("dstp://localhost/ts_to_emmenu"));

  HR = g_pNIDSCtl-> put_URL (bstrURL (bstr_t));
  HR = g_pNIDSCtl-> put_AccessMode (cwdsRead);

  b short;
  HR = g_pNIDSCtl-> SyncConnect (30000, & b);

  ICWData * pData = NULL;
  HR = g_pNIDSCtl-> get_Data (& pData);

  CComVariant varVal;
  HR = g_pNIDSCtl-> Update();

  HR = pData-> get_Value (& varVal);
  //
  VarVal HERE is always 0, regardless of the values in the data?
  //
  pData = NULL;

  HR = g_pNIDSCtl-> Disconnect();

  My question: is it still possible to recover a table of 4 floats using only nids.dll interfaces and if yes, can someone push me in the right direction or give me some advice.

  Thanks in advance

  Hello Peter,.

  Sorry I mixed things up... I really need a window because I wanted to be able to use INIDSCtl.SelectURL ().

  But there is no need to use DataSocket. The important things are:

  1. call CoInitializeEx() with COINIT_MULTITHREADED parameter.

  2. when 2 une fois connecte connected to the server, call INIDSCtl.GetStatus () repeatedly until it returns cwdsConnectionActive.

  3. call INIDSCtl.Update () and read your data.

  Here is a quick and dirty example you can try in conjunction with "DS Writer.vi' example:

  #define _WIN32_WINNT 0 x 0501

  #include
  #include
  #include

  #include

  #import 'nids.dll"no_namespace don't

  int main()
  {
  HRESULT hr = CoInitializeEx (NULL, COINIT_MULTITHREADED);
  {
  Instantiate DataSocket.
  DS INIDSCtlPtr;
  HR = ds. CreateInstance (__uuidof (CWDataSocket));

  To connect to the server.
  HR = ds-> ConnectTo (_bstr_t (L "dstp://localhost/wave"), cwdsRead);

  Wait until the connection is established.
  Status of CWDSStatus;
  While ((statut = ds->GetStatus()) == cwdsConnecting)
  {
  Sleep (100);
  }

  Get data.
  While ((hr = ds->Update()) == S_OK)
  {
  if(DS->GetDataUpdated() == valeur VARIANT_TRUE)
  {
  _variant_t retVal = ds->-> GetValue GetData();
  check the type of the VARIANT. It must be an array of double.
  If (V_VT(&retVal)! = (VT_ARRAY |)) VT_R8))
  throw _com_error (E_FAIL);

  Unpack the table.
  SAFEARRAY * psa = V_ARRAY (& retVal);
  If (psa is NOTHING)
  Throw _com_error (E_POINTER);

  He must have a dimension.
  If (psa-> SICGD! = 1).
  throw _com_error (E_FAIL);

  Double HUGEP * vals;
  HRESULT hr = S_OK;
  If (FAILED (hr = SafeArrayAccessData (psa, (Sub HUGEP *) & vals)))
  Throw _com_error (hr);

  for (long unsigned I = 0; i < psa-=""> rgsabound [0] .cElements; i ++)
  {
  std::cout< vals[i]=""><>
  }

  Table is no longer needed.
  If (FAILED (hr = SafeArrayUnaccessData (psa)))
  Throw _com_error (hr);
  }
  }
  }

  CoUninitialize();

  return 0;
  }

• How to create the SQL filter using XQuery FLWOR

  It is possible to create such a FLWOR expression that will be pushed down to SQL uses 'IN SQL"filtering?
  
  Assuming that the following function declaration:
  
  declare function tns:filterOnLevels($levels_as_xs:double+) {...
  
  I would like to create FLWOR expression that will be pushed down to this SQL:
  Select * from LEVELS where level IN ($levels)
  
  And tns:filterOnLevels (1,2,3) should run statement with ' where level IN (1,2,3). Type SQL filtering owe be lowered to SQL, because the execution of the query without constraint could train with too many records.
  
  This expression is possible to do in XQuery/XQSE or perhaps other extensions of fn - bea?
  
  I'm working on ODSI/Workshop 10.3 and Oracle 10 g.

  ODSI uses multiple GOLD instead of IN because optimizers (1) rewrite 'IN' as several GOLD anyway. and (2) OR is more general than 'IN,' since 'IN' can handle that (a) equal; and (b) a single multiple-column, while GOLD can also manipulate inequalities and several columns.

  In your example...

  declare function tns:filterOnLevels($levels_as_xs:double*) {(: use ' *' instead of '+' here, the optimizer will appreciate :))}

  for $l in $levels
  for $LEVELS in LEVELS()
  where $LEVELS/LEVEL = $l
  return
  $LEVEL

  If you look at the generated query plan, it should contain...

  SELECT = from LEVELS including LEVEL? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =?

• Problems while extracting the hours of the Date field

  Hi guys,.
  
  We hope that you do well.
  
  I am facing some problems during extraction of the hours of the date field. Here is an example of my orders table:-
  
  Select * from orders;
  
  Arrival time of Order_NO product name
  1 computer Office November 20, 10 10:10
  2 November 21, 10 17:26:34 portable
  3 22 January 11 printer 08:10
  
  Earlier, it is stated that the daily number of orders take place in the roll of the order, I used to write a query
  
  arrival_time > = trunc ((sysdate-1), 'DD')
  and arrival_time < trunc ((sysdate), 'DD')
  
  The above query gives me yesterday how many orders have been been held.
  
  Now I have the new requirement to report on every 4 hours the number of orders will be held. For example if the current time is 08:00 IST then the query must extraction from 04:00 until 08:00 how many orders took place. The report will take place at 12:00 IST which will give me an order took place from 08:00 until 12:00.
  
  The report will be run every 4 hours per day and generate report of orders taken place for the past 4 hours. I have a programmer who will run this query every hour, but how to understand to get the order at the request of details who arrived for the past 4 hours. I'm not able to do this using trunc.
  
  Can you please help me how to make this happen. I checked "Extract" also, but I am not convinced.
  
  Help, please.
  
  Thanks in advance

• Name of the node XML TreeControl

  Hello
  I have a tree control that is built using XML from an HTTP service call. Based on the node selected in the tree, I would like to add a conditional in my click function that performs an action that is different, based on the name of the XML node. I can retrieve the attributes of the node by using "mytree.selectedItem.@attribute" but I do not know how to retrieve the name of the node itself real?
  
  Can anyone provide me with the proper syntax?
  
  Thank you!
  

  There are two methods:
  XML. Name();
  and xml.localName ();
  I think that they the same æ unless you use namespaces.

  Hello

  I have to extract values in xml that includes several namepspaces.

  There is only one workspace names in fact (the default value).

  Normally, an empty xmlns UN-declare a default namespace declaration is inherited from the parent node.

  So, in your example, only node belongs to the default namespace.

  In this case, when you have to walk through the nodes belonging to some namespaces and others in any namespace, do not use the DEFAULT option in the WITH XMLNAMESPACES.

  Instead, declare a prefix and use it as needed for qualify of nodes.

  Another thing:

  Returns the local item: r {$i / eventtype,}

  What what do you want with "local:" here?

  The following should give the expected results:

  SELECT TMX.*

  of EXAMPLE_MESSAGES1

  XMLTABLE)

• Use the node property to get the value of control

  Hi all

  I know that you should keep the use of local variables to a minimum in order to avoid race conditions. Is this the same problem if you using the eg property node. a digital control?

  The reason why I want to do is to keep the son of the intersection when I need to use a control on one side of the diagram across the diagram...

  Basically to make the scheme simple and enjoyable to watch.

  I hope that makes sense!

  Good day!

  Kind regards

  Tommy

  Exactly. Perhaps, he creates the race conditions and should not be used. Using wires to connect the terminals is the approach only "Save".

  In addition, performance decreases in the following order:

  -Terminal (+)

  -variable (0)

  -property to value node set (-)

• How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

  new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

  

  Hi GerdW

  Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

  As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

  I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

  I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

  Mant thanks!

  NB. you will need to hit rΘpondre α and then quote my post to see the actual text; For the life of me, I can't get the forum properly displays things. In short, the string returned by the EXTRACT is escaped, while the XMLTABLE chain is unescaped.
  
  
  ETA: I looked through the standards xml from the list of available functions, and nothing seems relevant. {noformat} * scratches head * {noformat}

  You can emulate what do I EXTRACT / getStringVal () by projecting the node text() as XMLType and type-casting to VARCHAR2 in the SELECT clause:

  SQL> set scan off
  SQL>
  SQL> select cast(col1 as varchar2(20))
    2  from xmltable(
    3         '/root'
    4         passing xmltype('<unset>')
    5           columns col1 xmltype path 'test/text()'
    6       ) ;
  
  CAST(COL1ASVARCHAR2(20))
  ------------------------

• How to use the node function call library for a function in the dll with the data SUB type

  Hi all

  I would ask for your kind help

  I am facing a problem with the call library node.

  I have a C++ (stdcall) function, which has Sub as data type

  XXXX error code (hwnd, lid, getValue, * Sub data1, * Sub data2)

  data1 and data2 types are constantly changing based on the value of 'getValue '.

  Mainly I can use the call library node several times and adapt each node according to the types of data data1, data2 and extract the values and use in the code. Here is no question. Real question is:

  My question:

  How can I use a node of library time call and make a case according to the 'getvalue', who will control the data1, data2 data type. Here I really seeking solutions.

  My tests:

  I used varaints as entry to the libray call node of the data1, data2 and selected parameters in the call libraby node as "Adapt to type. Here labview just crashed.

  I appreciate your suggestions to feedbackand.

  Thank you

  Karine

  You must allocate enough space for data1 and data2, and then pass a pointer to this space. An easy way to do this is the function to initialize table. Set the U8 type and size for the number of bytes required. Pass this array to the function as a pointer of table data.

  After the function call returns, you need to extract the data in the table. You can do it manually, but a simple approach is to use the array of bytes to a string. Then, in a housing structure, use Unflatten chain to convert the string to the correct data type. This method also converts the "endianness" which will be probably necessary; Be sure to only set all entries for unflatten correctly.

• Read the nodes that have the same value as the subnodes - XML

  It is more of a general JAVA / XML problem, but given that it is going into my BlackBerry app I thought I'd see if anyone knows.

  Consider a simple XML document:

                      Whatever 1                   Whatever 2               Whatever 3       
  

  Using the standard org.w3c.dom, I can get the nodes in X by the practice...

  NodeList fullnodelist = doc.getElementsByTagName ("x");

  But if I want to go to the next set of 'e', I try to use something like...

  Element element = (Element) fullnodelist.item(0);NodeList nodes = pelement.getElementsByTagName("e");
  

  EXPECTED back '3' nodes (because there are 3 series of 'e'), but it returns '9' - because it gets all entries including the 'e' apperently.

  It would be nice in the above case, because I could probably go through and find what I'm looking for. The problem I have is that when the XML file looks like the following:

              whatever              Something Else                    whatever              Something Else            
  

  When I ask 'e' value, it returns 4, instead of (what I want) 2.

  I am simply not understand how DOM parsing works? Generally, in the past I used my own XML documents so I name never articles like this, but unfortunately this isn't my XML file and I don't have the choice to work like this.

  What I thought I would do, it is write a loop knots "drills down" so that I can combine each node...

    public static NodeList getNodeList(Element pelement, String find)
      {
          String[] nodesfind = Utilities.Split(find, "/");
          NodeList nodeList = null;
  
          for (int i = 0 ; i <= nodesfind.length - 1; i++ )
          {
              nodeList = pelement.getElementsByTagName( nodesfind[i] );
              pelement = (Element)nodeList.item(i);
          }
  
          // value of the nod we are looking for
          return nodeList;
      }
  

  .. While if adopted you ' s/e' in the service, he would return the 2 nodes I'm looking (or elements, perhaps I'm using the wrong terminology?). on the contrary, it returns all the 'e' nodes in this node.

  Anyway, if anyone is still with me and has a suggestion, it would be appreciated.

  Well, there is no doubt that there is a learning curve robust for XML programming. You can take an hour or two and go through one of the tutorials that are circulating on the net. (Like that of w3schools.com.)

  Basically, almost everything in XML is a node, the Document that returns the parser. The API for node tells you that you can test the node type you have by calling getNodeType, which returns one of the constants of type node (Node.ELEMENT_NODE, Node.TEXT_NODE, etc..) If necessary, you can then convert the variable to the corresponding interface (element, text, etc.).

  Similarly, the API documentation say you for any node, calling getChildNodes (or for an element node or Document getElementsByTagName) will give you a NodeList (a little non-types of nodes in the XML API), while calling getFirstChild and getNextSibling to any node will give you another node (or null ).

  Once you learn the API, writing logic of course is not all that hard. For example, if the only 'e' interest tags are those directly under the element root of the document (as shown in your example) you can simply go to them directly:

  Vector getTopENodes(Document doc) {  Vector vec = new Vector();  NodeList nodes = doc.getDocumentElement().getChildNodes();  int n = nodes.getLength();  for (int i = 0; i < n; ++i) {    Node node = nodes.item(i);    if (node.getNodeType() == Node.ELEMENT_NODE &&        "e".equals(node.getNodeName()))    {      vec.addElement(node);    }  }  return vec;}
  

  Note that this example does not assume that all children are nodes of element 'e '. the document could have comments, white space or something else that makes it into the DOM as comment, text or any other type of node.

  On the other hand, if you want to capture every "e" tag which is directly under the ' tag, no matter the level, then you need to do something a little more complicated (it's on the top of my head - no guarantee):

  static class NodeListImp implements NodeList {  private Vector nodes = new Vector();  public int getLength() {    return nodes.size();  }  public Node item(int index) {    return (Node) nodes.elementAt(index);  }  public add(Node node) {    nodes.addElement(node);  }}
  
  NodeList getTargetNodes(Document doc) {  NodeListImp list = new NodeListImp();  getTargetnodes(list, doc.getDocumentElement(), false);  return list;}
  
  void getTargetNodes(NodeListImp list, Node node, boolean parentIsS) {  if (node.getNodeType() == Node.ELEMENT_NODE) {    // node name is tag name for element nodes    String name = node.getNodeName();    if (parentIsS && "e".equals(name)) {      list.add(node);    }    parentIsS = "s".equals(name);    for (Node child = node.getFirstChild();         child != null;         child = child.getNextSibling())    {      getTargetNodes(list, child, parentIsS);    }  }}
  

  I hope that it gets the idea across.
