• How to read the value attribute and put inside?

  What happens if we want to read the attribute value? And want to put the data of runtime on the value of the attribute as
  
  < psoID ID = "user id" / >
  
  How to get the value of the ID as the user id. And how to put the run value on it?
  
  I can think about is that
  
  /psoID/@ID/value GOLD psoID/@ID/*[local-name () = 'value']
  
  And how to put the value inside ID ="? »
  
  Thank you

  Because we are dealing with a structure of type anyType you must use the functions of node (local name) in combination with predicates ([]) to read or write values (node) of the element:

  To read the value for example use the copy rule:

  
  
  
  

  This wil read:

  /processResponse/result/psoID/@ID

  on the message:

  
  
  
  
  

  You will see the value 'B '.

  To write, you use:

• read the values of an array element and by sending a digital output to a designated channel according to the value read from the table

  Hello world

  could someone help me before I get out of my hair. Here's my problem.

  I read 3 values of an array of 3 elements i.e. 1,2,3. These values are then compared to a constant value, example if the first element of the array is 1 and it meets the comparison condition can send a digital camera of output for that channel on data acquisition

  I want to be able to send a value from a table to its corresponding comparison and then on its designated channel on the acquisition of data, the whole point of this is due to the fact the table element will not always read the value 1,2,3 for example could be 2,3,1

  Here's one the vi I have so far

  If someone could help it would be much appreciated

  all the best

  Set value using Javascript is that in your browser page but is not yet available in the session. This is why the report does not return the expected results.

  Before you refresh the report, you need to set the session state from this point.

  You can configure after assigning a new value or before the report is updated to the element
  For interactive reports, is available built in
  You can go to report attributes > attributes advanced-> Page elements to submit and specify P2_X1 for the field (and any other page element that depends on the report)

  For standard reports, you can create a dynamic Action that is triggered 'before updating"report region, select PLSQL as action types, give a code BÉGIN END NULL; model and specify the name of the item in the item page to submit the field so that it affects the value of items in the session.

• 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.

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

• urgent request: how to read the value of a register using VISA read?

  Hello world

  This is a very urgent investigation. can someone help me please? Thank you very much!!

  I wrote a few commands in several registers using VISA write. now, I want to read the value of a different register.

  But the bytes returned are just the commands, I wrote before and a few other commands that I don't know what they are for.

  This is the format of the command, and I enclose the sheet... I want to read the value of register (0 * 41)

  .

  Ravens, if you have something more than me, do not so much it at all =)

  The command you have posted has several components:

  The gray area of the transport layer uses for a checksum

  several bits set to 0.

  a single bit to define if it's a read/write operation

  a byte to identify the register of interests.

  two bytes for the data.

  With what you have provided, there are only three things we need to worry:

  (1) set the R/W bit to 0 to mean we're reading rather than write.

  (2) set the second byte 0 x 41 to focus on the register of interests.

  (3) with a reading, I can't imagine the last issue of two bytes.  They probably ignored.  The documentation you provided does nothing to explain this.  The most logical thing I can think is that these two bits contain the data, you go to the registry if you set the R/W bit to 1.

  There are two parts to this communication.  The first part is an entry VISA to send this control unit.  It is likely that you will need to complete the message.  You will need to know how to do this.

  The device must respond with the message that you mentioned in the original post.  Crows is right.  He's coming back as a string.  You can use the subset of string to separate the components defined by the standard.  You can use these components to determine if the data is legitimate and then do what you want with the data.

• How to read the values of the field of LOV disabled?

  Hi all

  I have a requirement, based on values that we entered one of the LOV fields, then we are arising from the new values based on the value that we entered this field of LOV. And then I must by default new LOV values derived in a two other fields of LOV and then disable them. Once the fields are disabled, then I'm not able to read the values using the pagecontext.getparameter... I get nothing when I tried to read using the pagecontext.getparameter.

  Pointers on how to read the values of disabled field/LOV?

  Thank you
  Clarriiza

  1. you already have values, and that's what you set in the LOV before turning off, right? So why do you need to recover again from the LOV.

  2. are you disabling or making it readonly? I think that if it is disabled, you might still be able to get the value using pageContext.getParameter.

  3 have you tried to get the handle to the LOV bean and get the value using lovBean.getValue (pageContext)?

  4. another Option is to combine the value of a FormValue Bean also (as well as the LOV bean) and retrieve it from FormValue.

  5 BTW, why are, why you're seen LOV if you disable it? Can't you just a TextBox?

  See you soon

• Read the values of luminance of the image

  Hello

  I would like to create a plugin that changes the saturation of an image based on luma values, similar to the curve of Lum VS Sam of Davinci resolve.

  How to read the values of luminance of an image? I couldn't find any image manipulation methods in the SDK, but maybe I'm in the right place.

  Thank you

  To attach the Lum VS DR Sam curve.

  

  The SDK API won't let you change individual values in pixels, i.e. what, I should change the saturation of a pixel from its brightness.

  The SDK lets you change even develop settings can be changed in the UI (for example an exhibition), via picture: applyDevelopPreset (), the:applyDevelopSettings() papers and LrDevelopController photo.  But none of the sliders in the user interface let you accomplish your purpose, if you can not do with the SDK.

  You can write an external editing (for example in C++ or Swift) application which provides such a feature TIFF.  You would be it interface to LR as a 'external editing plugin', as the Nik plugins.   But I don't think that's what you think.

• How to read the value of an independent textInput element inside the method?

  Hello
  
  I had a group of detail based on a readonly viewobject. I added an independent element textInput, you say, EndDate to this group that the user can enter a value inside. Now, when I run the app I select a row in the table and press a button that triggers a method inside a bean. My question is how I read the value in independent textInput (EndDate) within the method element?
  
  getTable () .getRowData () does not print the unbound attribute. It seems that it only contains attributes underlying viewobject
  
  I use JDev 11.1.1.4
  
  Kind regards
  Will do

  Will do,

  You can better create a transitional attribute for that in your view object, so you can use a regular expression #{row.bindings...} to get the value.

• Save and read the value of control using xml

  I need to read and update the controls with the values they have the previous time the vi has been run. Joined a vi that I come up with. I can record control values; When I apply the section which should read and update control values, I get this error "the XML tag describing the type of data does not match the wired type". Do we know why? Attachment: test vi and xml control file.

  As far I can tell it seems that you have found a bug. The XML Unflatten handles not properly cluster in a chain, and a variant of something. The Get All method returns an array of clusters, with each group being a string and a Variant.

  If you follow these steps:

  

  no error is generated.

  But, if you do this:

  

  you get an error.

  Looks like a bug to me.

• read the value of the variable binding

  Hello
  
  I was debugging a java application and in the process, I wanted to know what values the request as a bind variable. So, I checked v$ sql_bind_capture and activated the trace on the session. Unfortunately the data type is TIMESTAMP, so the view did not show a value and I got the trace was a memory dump that is not helpful for me:

   Bind#1
    oacdty=180 mxl=11(11) mxlc=00 mal=00 scl=00 pre=00
    oacflg=03 fl2=1000000 frm=01 csi=873 siz=0 off=24
    kxsbbbfp=fffffd7ffdb6fbd0  bln=11  avl=07  flg=01
    value=
  Dump of memory from 0xFFFFFD7FFDB6FBD0 to 0xFFFFFD7FFDB6FBD7
  FFFFFD7FFDB6FBD0 0D0B6C78 00010101                    [xl......]

  Is there a function/method to convert a timestamp or at least vice versa?

  Just run this little test:

  SQL> CREATE TABLE t (c1 TIMESTAMP);
  
  Table created.
  
  SQL> INSERT INTO t VALUES (TRUNC(SYSTIMESTAMP));
  
  1 row created.
  
  SQL> COMMIT;
  
  Commit complete.
  
  SQL> SELECT TO_CHAR(c1) FROM t
    2  UNION
    3  SELECT DUMP(c1) FROM t;
  
  TO_CHAR(C1)
  --------------------------------------------------------------------------------
  13-NOV-08 00.00.00.000000
  Typ=180 Len=7: 120,108,11,13,1,1,1
  

  Convert decimal to hex you gives 78, 6 C, 0, 0 D, 01, 01, 01 what byte order accountant reverse is the same as your memory dump. So I think the bind value is 00:00:00:000000 November 13, 2008.

  Not very well how to recover of the hexagon directly at the time, but I do not know someone knows!

  In fact, Google has been very helpful... take 100 on the first two decimal values: 120-100 = 20; 108-100 = 08, to give you the year: 2008. Then 11 and 13 are the month and day. The rest is hour + 1 minute + 1, the second + 1. So just convert your hex decimal and you should be able to discern the value!
