• How to convert the Ascii string containing hex to hex string info?

  Dear all,

  I am busy doing a control/reading program for pumps of ISCO.

  Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

  Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

  So to summarize:

  I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

• Several analog inputs with different configuration differential/CSR

  Hello

  Can anyone tell how to measure two analog inputs with different configurations using a USB-6009?
  I am aware of the syntax for create virtual channels for the channels DAQmx create virtual so I created two strings using Dev3 / ai0:1 but I would like the first string of the CSR and the second to be differential.
  So far I have found no way to specify the configuration of the separate channels.

• Related problem of Hex String

  Hello

  I would like to add 20hex string together & divide by 20, but somehow, I can't get the correct result.

  Attach with my vi here.

  Thank you and best regards,

  Simon

  Try the attached VI, I changed the lag that you used in the chain of research/split of 2 because you view the input as hex string, so when labview works on the rope he works on the ASCII representation of the string (which is a character), even if your display is in hexadecimal (two characters with an ascii character) so you only need to divide at an offset of 2 instead of 4. For example, direction = FFFF.

• Save pictures png with different names...

  Hello guys,.

  I'm not so familiar with Labview and I want help. I have a Vi which is actually control 32 RBG lights. We use the DMX Protocol... to each time a directed is on and then we take a picture, then the led goes out. The second goes on then end and on... We have 8leds in 4corners... So, we corner1_led1, corner1_led2 up to corner4_led8. Ultimately, we are 32 saves png pictures. What I want is to record photos with different names and numbers starting from 1 instead of 0... For example, if we choose the white light and save the images in 'News' images will be named 'new_white_0_0' instead of 'new_white_1_1 '. You have an idea how I can change it?

  Attached the names of current photos and Vi.

  Any comments would be useful.

  Thank you.

  The terminal of indexing ([i] in the loop for) starts at 0. When you create your file name, use the primitive "to increment" digital palette. Then your file names will start at 1 instead of 0.

  I noticed your VI that you do a lot of string concatenation to build the path/name of the file, you can use the format string and build the screw to make the somewhat simpler schema. You can also update the deprecated functions (for example, the file open) with modern equivalents.

• use different JADs to deploy a COD with different properties

  I've never had different JADs to work for the Web site deployment.

  This is the problem, I use getAppProperty MIDLET to get a property.

  I create a file myMidlet.COD with myMidlet.jad which has a property of the HOST.

  I have ten different JADs with different HOST property on a Web site for

  a myMidlet.COD that will be deployed. The midelt deploys nicely on the Blackberry

  but the HOST is the same as that used to build cod. They gave me a code snippet and

  added some debug statements to see what this thing of Module

  public class mybbProperty {}
  CodeModuleGroup [] allGroups;
  CodeModuleGroup myGroup = null;
  String moduleName;
  Boolean flag = true;

  public void mybbProperty() {}
  }

  public void init() {}
  versForm.debugtext += '\n init';

  AllGroups [CodeModuleGroup] is CodeModuleGroupManager.loadAll ();.
  versForm.debugtext += "\ngroup;
  moduleName = ApplicationDescriptor.currentApplicationDescriptor () .getModuleName ();
  versForm.debugtext mode += "\n" + moduleName;   Note ModuleName is correct and is "myMidlet".

  for (int i = 0; i)< allgroups.length;="" i++)="">
  versForm.debugtext += "\n"+allGroups[i].getFriendlyName ();

  If (allGroups [i] .getFriendlyName () .equals ("myMidlet")) {}
  versForm.debugtext += "\n"+allGroups[i].getFriendlyName ();
  versForm.debugtext += "' \n * found"; "
  for (Enumeration e = allGroups [i] .getModules ();)
  e.hasMoreElements () {}
  versForm.debugtext += "\n *"+ e.nextElement (); "
  }
  myGroup = allGroups [i];
  break;
  }
  for (Enumeration e = allGroups [i] .getModules ();)
  e.hasMoreElements () {}
  versForm.debugtext += "\n *"+ e.nextElement (); "
  //            }

  If (allGroups [i] .containsModule (moduleName)) {}
  myGroup = allGroups [i];
  break;
  }
  }
  versForm.debugtext += "\n end";

  }

  public String getAppProperty (String name) {}
  If (flag)
  init();
  flag = false;
  versForm.debugtext += "\n getAppProp"+ name;
  If (MyGroup is nothing)
  Returns a null value.
  Return myGroup.getProperty (name);
  }
  }

  I use the function mybbProperty.getAppProperty ("AppMyHost");

  I noticed that the getFriendlyName() is the name of my Application, so I use it and

  print information. Did I get this

  mybbProperty mybb = new mybbProperty();

  String s = mybb.getAppProperty ("AppMyHOST");

  myMidlet

  * Found

  * myMidlet-3

  * myMidlet-2

  * myMidlet-1

  of course, which returns null. So how do JAD another properties which was used to deploy the

  App for Blackberry. In Nokia its pretty simple use MIDlet getAppProperty() you need a jad and jar for

  deploy it.

  In any case, I don't know which module to get. The JAD I used to deploy the cod was called green.jad

  so I have no idea why myMidlet is important. I wouldn't see green.jad somewhere?

  Anyway, I would appreciate any code that does this correctly.

  Please see this thread on this issue.

• Mr President, how can I enter two rows at the same time with different default values that only the first line to use see?

  Mr President.

  My worm jdev is 12.2.1

  How to enter two rows at the same time with different default values that only the first line to use see?

  Suppose I have a table with four fields as below

  "DEBIT" VARCHAR2(7) , 
    "DRNAME" VARCHAR2(50),
    "CREDIT" VARCHAR2(7) , 
    "CRNAME" VARCHAR2(50),
  

  Now I want that when I click on a button (create an insert) to create the first line with the default values below

  

  So if I click on the button and then validate the second row with different values is also inserted on commit.

  The value of the second row are like the picture below

  

  But the second row should be invisible. It could be achieved by adding vc in the vo.

  The difficult part in my question is therefore, to add the second row with the new default values.

  Because I already added default values in the first row.

  Now how to add second time default values.

• How to read the data with different XML schemas within the unique connection?

  • I have Oracle database 11g
  • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
  • I have several tables, each has an XMLType column, all based on patterns.
  • There are three XML schemas different registered in the DB
  • Maybe I need to read the XML data in multiple tables.
  • If all the XMLTypes have the same XML schema, there is no problem,
  • If patterns are different, the second reading will throw BindXMLException.
  • If I reset the connection between the readings of the XMLType column with different schemas, it works.

  The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

  Code to get data from XMLType is the implementation of case study:

   1   ResultSet resultSet = statement.executeQuery( sql ) ; 
   2   String result = null ; 
   3    while(resultSet.next()) { 
   4   SQLXML sqlxml = resultSet.getSQLXML(1) ; 
   5   result = sqlxml.getString() ; 
   6   sqlxml.free(); 
   7   } 
   8   resultSet.close(); 
   9    return result ; 
  

  It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

   1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
  

  Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

• Photos with different apple id: s

  Any way to sort photos taken with various apple id: s in photos for mac? I have three different iPhones that has been moved from parents to children. Is there anyway to sort images with different apple id: s? I heard that there is way to sort different (smart folder) with the model of phone, but this is not enough cause phones were used earlier by the parents. And I want to use only a single library of pictures, so the different IDs: s for mac is not the solution. It would be nice to get this functionality.

  You can use smart albums with a combination of constraints: the model of the iPhone and the date rank when the iPhone has been used by a person in particular. If the iPhone has been in use you make in the years 2012 and 2013 creates a smart album that will check for the ipHone and the date range.  Then announces a keyword "Photo by Me" of all the photos in this album. Do the same for the other ranges of iPhones and date and assign the photographer as a key word.

  If you keep marking new imports with a keyword of photographer then you can create smart albums for every photographer.
