• [ORA-22905] How to read a field of an object inside another object?

  Greetings,
  
  I'm a student and in an exercise working with Oracle object-oriented programming features.
  
  In the database, we have defined an object type, which is then considered as within another type of object. The thing is, that I can not read an attribute of the internal object. I've read dozens of Web sites, but none of them helped until now. I also read the PL/SQL user's Guide and the reference document.
  
  The internal object is defined as follows:
  

  create type address_t as object (
          street varchar(50),
          city varchar(50),
          pcode number(5,0)
          );

  The external object has an object of type address_t inside:
  

  CREATE TYPE professor_t as OBJECT(
            code number(2),
            p_name varchar(50),
            address address_t,
            );

  There is also a table named PROFESSORS that stores objects of type professor_t
  
  First of all, with a simple SQL test I can see the data inside the Professor of the object, even the address_t of the object:
  

  SELECT * FROM PROFESSORS WHERE CODE = 13;

  Returns the following:
  

  CODE    |         NAME      |       ADDRESS
  ---------------------------------------------------------------------------------
  13      |         JOHN     |       MYSCHEMA.ADDRESS_T('FIFTH AVENUE','NEW YORK',12345)

  The thing is, I want to read the field Street of the object address (of type address_t) inside Professor (of type professor_t).
  
  I saw everywhere where the way forward is to use dot notation, and I've seen examples of the VALUE control, but none of the following SQL statements work:
  
  

  SELECT VALUE(ADDRESS.STREET) FROM(
    SELECT CODE,P_NAME,ADDRESS FROM PROFESSORS WHERE CODE = 13);
    
  SELECT ADDRESS.STREET FROM PROFESSORS WHERE CODE = 13;
  
  SELECT PROFESSOR.ADDRESS.STREET FROM PROFESSORS WHERE CODE = 13;

  I would appreciate if someone could show me how to access the values of the field of the object inside an object.
  
  Thanks in advance,
  -David

• How to read the value of the javascript component text entry

  Hello
  
  I need to add ' / ' after user entering the first two characters and before entering the third character of character to the value of input text.
  To meet this requirement, I add a clientListener of type keyPress to input text element.
  My question is how to read the value entered by the user to input text in java script component (the clientListener method).
  
  I faked my requirement in a sample application @ http://www.easy-share.com/1912896093/format.7z
  
  Please help solve this problem.
  
  Thank you
  Kiran

  For setting/getting the value, you can even view:

  
  
  
  function keyPress (event) {}
  component = event.getSource ();
  
  Alert (Component.getSubmittedValue ());
  
  {component.setValue ("new value '");}
  ]]>

• How to read the table of string returned by the DLL

  I developed DLLS in labview that takes 2 input parameters as a string and returns an array of strings in return. How can I read back this array returned strings in labview? I tried to return a string and I can't able to read. But how to read a table?

  Is the signature of the function – void GetLoginInfo (char [] DBPath, char [UserName], LStrHandleArray * table)

  Shrinivas

  I found the solution. When you configure the node to call a library function, the argument (in which we expect an array of string) type should be chosen as "Adapt to the Type" and data format to be "pointers to the sleeves.

• How to read the objects and collections dynamically?

  As I suggested, you can define your own method of "diff" for the object. You haven't told us exactly what form you would like to work to take. I'll define a (pretty useless) function which will just create a string that tells you how to modify the data of an object to match the data in another. Obviously, you would like a more useful output. Potentially, rather than a member function, you can choose a procedure Member who emits DML is required for the underlying table is necessary.

• How to read the value of the selected item in the DropDownList control?

  Hello

  The DropDownList component has a selectedItem property is supposed to return a ListBase.

  But what I want is just the 'chain' which is supposed to be the selected item in the DropDownList control.

  How to read this value?

  Thank you

  -Malena

  You are misreading the documentation. ListBase.selectedItem returns an object. This item comes directly from your data provider, so you just have to go up or go for any property you need.

• How to read the tag bluetooth data in labview 2015 running on Windows 10

  Hi all

  I have a Development Board Nordic semiconductor nr51. This card is programmed as a tag bluetooth which simply announces his address with 16 bits of data appended to the end.

  My laptop came with loan materials smart bluetooth. I installed an app interactor lighthouse to bluetooth on my laptop and the software is able to detect the tag as if shown on the image below.

  

  I wanted to write a LabVIEW program that will simply be careful bluetooth headlights and notify me in my computer every time a lighthouse with the specified address is detected. This mobile application below is provided by the manufactuerer of the Board of Directors and I wanted to develop a LabVIEW program something similar to what will read the given data and extract values.

  

  Somehow, all the sample applications provided data only shows how to read and write in a connected bletooth device but not analysis for tags. I also tried using the Bluetooth ' discover ' and it does not detect the bluetooth beacons.

  Could someone provide me with the necessary information or example program for detecting / reading of tags bluetooth in LabVIEW 2015 running on Windows 10?

  Do I need to install a third-party software to read data from bluetooth?

  Bluetooth in LabVIEW function nodes using the Winsock interface to access bluetooth resources. This works very well for Bluetooth 2.0 devices but not Bluetooth 4.0 devices WHEAT aka. Microsoft has created a completely different interface for these resources API as the model of overall service for WHEAT devices has radically changed.

  The API to use WHEAT devices is the API of the GATT (generic attribute profile) in Windows. There is supposedly a .net interface available that you can try to use (Windows.Devices.Bluetooth.GenericAttributeProfile). The WinAPI to lower level (https://msdn.microsoft.com/en-us/library/windows/hardware/hh450825(v=vs.85).aspx) is a C DLL API and does not lend at all to be called directly by the LabVIEW call library node, since some of the parameters of the function are quite complicated and you need to also access the SetupDI APIs to enumerate resources WHEAT and even harder to function parameters. In order to access this low-level API to write an intermediate DLL which results in low level API C a more acceptable API for LabVIEW.

  Another possible problem is that Windows don't at least in Windows 8 not allows devices to pair per program. Microsoft wanted to force developers in the use of the "inbox" experience, which means that all users must go through Microsoft provided service pairing, instead of each request for implementation of his own matching technique.

• How to re - install IPDiag32.dll

  I have an error message when I start the computer. I need to reinstall the IPDiag32.dll component because it is not located.  Can someone advise me how to do it.

  Thank you.

  Rather than trying to reinstall the DLL, I think that you should completely remove the installed program.  The DLL belongs to Visual IP InSight, do you really need this program that runs on your computer?

  Do Safe Mode system restore, if it is impossible to do in Normal Mode.

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.
