• How to make your custom data type used in your QListDataModel to QML?

  I have QListDataModel filled with objects of a custom class carying data and defined with Q_DECLARE_METATYPE. So far, it works however I can't access the data in qml:

  e.g. text: ListItemData.Name
  

  I read that this can be solved by letting QML know your custom class/type, but how to do this?

  See

  https://developer.BlackBerry.com/native/documentation/Cascades/dev/integrating_cpp_qml/

  example:

  qmlRegisterType("com.isec7.materials", 1, 0, "Account");
  

• How to delete a line item / of a custom Data Type?

  Hi all
  
  I can't tried to delete a line of a custom data type.
  
  As you will see in the code below I add a line to an array of Type (this is done several times). I then loop through each row in the type of array and pass it the id in a separate function. Once it is I so need to remove this item from the array Type - that's where I think my syntax is wrong because I get an error "ORA-00903: invalid table name.
  
  Clear code

   DELETE FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE docVersionID = l_DocVersID;

  Complete code

  l_DeleteList.extend;
  l_DeleteList(l_DeleteList.last) := DOCVERSIONID(l_DocVersID);
  
  .......................
  
  select count(*) INTO v_count FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE));
    -- loop temp table and delete document versions
    WHILE v_count > 0
    LOOP
    BEGIN
      SELECT docVersionID INTO l_DocVersID FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE ROWNUM = 1;
      DeleteSingleDocumentVersion(l_DocVersID);
      DELETE FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE docVersionID = l_DocVersID;
      select count(*) INTO v_count FROM l_DeleteList;
    END;
    END LOOP;

  Thanks in advance,

  Trim element removes it from the end of the collection... but you are a loop of the collection from the first to the last clue.

  If you use delete then the item is deleted but index still exists... then array.last and County are not equal...

  You can use something as shown in this example (rather than use a time loop on many items)... after deleting an item to browse a table...

  SQL> Declare
    2     TYPE    TYP_TAB IS TABLE OF PLS_INTEGER ;
    3     my_tab  TYP_TAB := TYP_TAB( 1, 2, 3, 4, 5 );
    4     v       Pls_Integer ;
    5  Begin
    6     my_tab.DELETE(2) ;
    7     v := my_tab.first ;
    8     Loop
    9        Dbms_Output.Put_Line( 'my_tab(' || Ltrim(To_char(v)) || ') = ' || my_tab(v) ) ;
   10        v := my_tab.NEXT(v) ; -- get the next valid subscript
   11        Exit When v IS NULL ;
   12     End loop ;
   13  End ;
   14  /
  my_tab(1) = 1
  my_tab(3) = 3
  my_tab(4) = 4
  my_tab(5) = 5

• Where to define new custom data types?

  Hello

  In the past (TS 3.5) I created our own range of custom type file that has been used

  to store the new data types and then referred the case to other colleagues. The file would be

  stored in the ...\Program Files\...\User area.

  My question arose because we now use the TS 4.1/4.2, which is no longer a separate

  Directories of NOR and user in \Program Files.

  Because now I want to change an existing custom data type, I find that our range of custom type has

  fallen by the way side, forgotten.

  Even though I can see the custom data definitions within the sequence of type files that use

  custom data types, which means that I can edit them locally, I intend to return to

  a range of custom type, i.e. comprehensive definition.

  What is the relationship between the definitions in a range of custom type and custom data

  definitions of type of a file of sequence?

  When a palette to update file a file of sequence?, who takes over in the event of conflicts?

  is a really necessary sequence files palette file if they are separated by using the same custom data type

  can update the other? What is good practice when defining custom types of data?

  Thank you

  Gary.

  Hey guys,.

  This is a very interesting thread, and I've got everything right, in heart, with advice given so far. I just wanted to offer some additional tips on the conflicts of kind - with more response, the initial question concerning the definition of what is priority in case of conflict.

  It is important to note that TestStand uses type names and version numbers to identify the different types. It is also important to note that when you use a definition of type of customers within a sequence, the sequence (.seq) file containing the sequence will keep a copy of the type definition. This greatly facilitates distributed sequence files. However, it also opens the door to potential conflicts type.

  TestStand allows only one type of unique name to be loaded into memory at any given time, so that it uses the number of versions of the type to try to resolve these conflicts automatically. For example, TestStand can be configured to load any type is the largest version number (note that this can be changed via the tab Preferences dialog box Options of Station).

  All this information and more are found in the following tutorials...

• Custom data type

  We use a custom data type container and add variables to use in the sequence inhabitants.

  It seems that the field of the local variable names having to match domain names that they have seized originally in the custom data type container.

  We want to reuse the custom several times in the sequence container for data type and would like to have descriptive field names of their use, which changes throughout the sequence.

  Is it possible to just rename the names of the fields of a local variable is of the type, data type container custom, while maintaining the field names the original custom data type container?

  With the help of TestStand 2013

  Thank you

  Hi CC57,

  I also recommend trying a templateVariable. You can use this to create a container with a particular name that you can copy in various places in the variable pane and change the names of the properties of confined there.

• DLL custom data type

  I try to use a DLL in LabView that talks about an acquisition card. One of the functions requires a custom data type (MID2250_MDConfig_t) that LabView does not support by default. It is defined in the C header file as follows:

  typedef struct
  {
  int CoordsX;
  int CoordsY;
  } MID2250_PointCorrds_t;

  typedef struct
  {
  MID2250_PointCorrds_t ULPoint [4];
  MID2250_PointCorrds_t BRPoint [4];
  unsigned short u32SADThresholdValues [4];
  unsigned short u32MVThresholdValues [4];
  unsigned short u32SensitivityValues [4];
  } MID2250_MDConfig_t;

  Is there a way I can integrate this data type in LabView correctly. I saw people talking about wrapper dll on this forum but I'm a bit confused as to who. Can I create a similar cluster in LabView and pass it to the function using "node of the library call?

  Since the tables are all fixed size (and not huge), they really are inline in the structure. This means that you can simulate a cluster containing many elements inside because it is the elements of the array. The first Point of the UL would be a cluster containing 4 cluster with each two int32 in it. Ditto for the second element. The third is a cluster with 4 uInt32 and so on.

  Then configure the setting to adjust the type and thread this cluster, and voila.

• Causing problems of custom data type to deploy the shared target RT variable

  I seem to have some difficulty in using a shared variable published network created from a customized data type when it is deployed as an executable on a target of cRIO RT.  I'll start by describing why I think that this is the rub.  I created my RT VI in the LabVIEW (LV 2012) development environment and everything works fine.  This VI is quite simple, because these were quickly devolved into an exercise in debugging.  The RT VI begins by simply flashing the LED to a couple of times and then starts a loop simple acquisition to read some values out of the material using the analytical engine (while still flashing the LED of the user).  After reading the material, the values are grouped in a cluster and written in a shared variable published to the network defined by a custom control type def.  The custom control contains five floats double precision.  If it's important, the RT cRIO system hosts the shared variable in this case.

  So I have that deploy in the development environment, and everything works fine.  The LED flashes merrily along, telling me that the program runs correctly.  Running a VI host who reads the shared network has published variable gives the desired result.  Everything is good.

  Now, I want the cRIO system to run this simple program by itself at startup.  I build, set it as start VI, deploy it, and then restart the cRIO target.  The LED never flashing... the VI doesn't seem to work.  I'll spare you the major part of the work of debugging and access to the end.  I basically "diagram Disabled" various sections of the code up to the VI began to run correctly in an executable file.  I kept reducing the size of the disabled code until something has been disabled: the writing in the shared variable for the custom data type.

  So, I guess my question is this: are custom data types defined by type def would be personalized orders authorized executables to RT?  I read through the cRIO Developers Guide, my book of development in real time course of NOR and the white paper using shared Variables and I see nothing that forbids it.  I know that there are things not allowed in the executable files that are allowed in the development environment (property nodes façade, dialogue live, operating system specific calls, etc.), but no mention of the shared variable type custom data.  Any ideas as to why my VI is running in the development environment, but does not update unless I have delete the entry on the published network variable shared?

  Thank you in advance for your help!

  You must disconnect the data types of variables and then recompile. You can find it useful to keep on disk, a copy of the original lvlib.

  Don't know if this is a bug or not. It was suggested by someone in the forum that putting the ctl files in the right position (the disk? in the draft?) would allow the rtexe start; I did a quick check and it didn't work then I dropped the tests more far.

• Help the insertion of an unknown number of lines in a custom Data Type

  Hi all
  
  I need help in the insertion of an unknown number of lines in a custom Data Type
  
  In Oracle I was thinking something like...
  

  CREATE OR REPLACE TYPE &HKDB_Schema_Name..SOMEDATA AS OBJECT (ID int, Name varchar2);
  /
  CREATE OR REPLACE TYPE &HKDB_Schema_Name..TYP_TABLE AS TABLE OF &HKDB_Schema_Name..SOMEDATA;
  /
  
  CREATE OR REPLACE PROCEDURE &HKDB_Schema_Name..SProc1
  (
  )
  AS
  l_TempTable TYP_TABLE := TYP_TABLE();
  v_count NUMBER := 0;
  l_ID int;
  l_Name varchar2(200);
  BEGIN
   
    LOOP
    -- exit the loop if the select returns no results. (look if exists in l_TempTable)
    v_count := SELECT COUNT(*) FROM Person p WHERE p.ID NOT IN (SELECT ID FROM TABLE(CAST(l_kgListTable AS TEMP_KGID_TABLE)));
  
    -- select the top result
    SELECT p.ID, p.UserName INTO l_ID, l_Name FROM Person p WHERE p.ID NOT IN (SELECT ID FROM TABLE(CAST(l_kgListTable AS TEMP_KGID_TABLE)))  
    AND ROW_NUM = 1;
  
    insert data into custom data type
    l_TempTable.extend;
    l_TempTable(l_TempTable.last) := SOMEDATA(l_ID, l_Name);
  
    EXIT WHEN v_count < 1;
    END LOOP;
  END SProc1;

  While I don't know this will probably do the job, it feels not very effective, have to select where the argument no_lig = 1 and then insert a facility on time. Is there a better way to do it?
  
  Basically, it's a migration of a MSSQL stored procedure where the equivalent would be...
  

  DECLARE @TempTable TABLE (ID int, Name varchar)
  
  INSERT INTO @TempTable (ID, Name) (SELECT ID, UserName FROM Persons)

  Thanks in advance,
  Toby

  Oh sorry you posted that before but I missed it. In this case maybe you should simply remove the

  as "HasChildren"{pre} part. This is only valid for a column name, but you input that expression directly into a type. It is not a column at this point.

• How to create a custom control for a button where the look apply to everyone else but not the Boolean text?

  Hi all

  I would like to create a button custom as a master, so that if I change the look of the master all other buttons are changed.

  I did it with a custom control, such as a 'type strict def' otherwise the look will change , BUT if I do this as a strict type def I can't change the Boolean text more which should be different on each button.

  How to create a master control of a button where the look apply to everyone else but not the Boolean text?

  Steve Chandler wrote:

  I don't think that you can do. I just looked and as I suspected the Boolean property text is read only for strict typedefs, you cannot use the nodes property to change the text.

  As a just solution make it a typedef. When you want to change the open look the typedef and strict rendering, make your changes, then make no strict again. You will need to update the text Boolean yet once for all instances. Kind of pain. This is perhaps something for the exchange of ideas.

  Alternatively, remove Boolean text and replace with legend

• How to determine if a data type is used in the comic book?

  Background:
  I am currently planning to install GoldenGate proof of Concept and have questions about the data types supported by the capture mode (pg 1-5, 1-6 in the installation guide). Is not in itself a matter of GoldenGate.
  
  Our source and target databases are 11.2.0.2
  The GG server will be 11.2.0.3
  I'm new to the environment and want to confirm that we needn't upgrade the source and target the DBs to 11.2.0.3 in order to use the integrated capture mode. This forces me to know if 3 specific types of data are used in the comics. The problem is, Oracle docs aren't clear to me, when they refer to 3 specific data types.
  
  Here's the question:
  
  Does anyone know how I can confirm that the following 3 data types are used in the DB by querying the dictionary: "XML stored in binary form',"XML stored as object-relational","abstract data Type "?
  
  If I select the types of data separate from dba_tab_columns, I see no data enumerated type that indicates, for example, that an XML string is stored as a ' binary '.
  
  For me, when Oracle made reference to a "stored as binary XML" on page 1-6 on the installation guide, I guess that makes Oracle refers to a BLOB that contains an XML reference, but I can't be sure.
  
  Someone has an idea that they could share? I just want to confirm that we do not have to upgrade our source and target DBs at 11.2.0.3 by searching in the database is possible to confirm that the above 3 data types are not used by the application.
  
  Thanks in advance for any help.

  You should find XML columns stored in binary form or CLOB using the DBA_XML_TAB_COLS view referenced in http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb01int.htm#g644983.

  You should find XML tables using storage relational object in the view DBA_OBJECT_TABLES with:

  select
  owner,
  table_name,
  table_type
  from
  dba_object_tables
  where
  table_type='XMLTYPE';
  

  To abstract data type, you can query DBA_TAB_COLUMNS using ADT as literal for DATA_TYPE column:

• BB10: How to create a custom Menu

  Hello world

  I need to create a custom menu for BB10. That's how I want (see the two screenshos):

  

  • It must be a bar at the top of the screen. Just like a BB10 'Title Bar', it should have a title. But he must also have two buttons: one on the left of the bar and the other on the right of the bar.
  • When you press the left button, a custom tab menu appears to the left of the screen. It also has a title and a menu with icons and images/background color list.

  I don't know if it's possible to do that yet, but I heard that you can do this by using "Custom Control"s. I tried with "Glass in", "Application Menu", "Menu", "Action Menu" and 'Title Bar' but I think that none of them responds to what I need.

  Any idea?

   

  Thank you very much.

  Hello!

  I think that this is possible, but requires coding.

  Create the menu in a container offscreen, layout of the container the DispositionAbsolue value (you can specify x & y) and drag the container into the visible area with animation.

  Create title bar as a container with two ImageButtons and a label. Slide the container to the right.

  Or even use one container for menu and title bar, just create half of the items off the screen.

  When the positioning of the controls, you can use the device resolution in order to avoid hard-coding the values:

  DisplayInfo display;
  int displayWidth = display.pixelSize().width();
  

  Animations are created by combining the ParallelAnimation, the SequentialAnimation and the different transitions.
