• Sliders are right-handed (pointing to the left) after I affecting the computer I want options for lefties.

  Original title: cursors

  As a left-handed user, I am frustrated with the sliders that are just given (pointing to the left) after that I asked the computer I want to left-handed options.

  As a non-tech user, I find it frustrating that the cursor does not change from right to left, or automatically at my request.

  Is it not possible to add this as a feature of the dialog box when you select handedness for the mouse buttons and other Visual AIDS?

  Thank you

  PS: I'd rather Win 3.1 :)

  Boyfriend sorry there is no such feature to change the cursor. It could be a design limitation.

• Save the shuttle point

  Hello

  I am trying to record the content of an element of the shuttle. I m using a "Save"-button that triggers a process (PL/SQL anonymous block). "."

  The content of the element of the shuttle should be stored in a table.

  The point of shuttle from filling with a calculation of work. Store new items that have been enjoy on the left side to the right side works just as well.

  Unfortunately I m not able to delete an existing element on the right side.

  If I remove an item from the right to the left and click on the button "Save", I get the error "ORA-01722: invalid number". "."

  I m using the following PL/SQL block:

  DECLARE
    v_count        NUMBER  := 0;
    v_shuttle_ids  VARCHAR2(1000);
    v_shuttle      APEX_APPLICATION_GLOBAL.VC_ARR2;
  BEGIN
    v_shuttle := APEX_UTIL.STRING_TO_TABLE(:P47_PFLANZLICHE_HERKUNFT);
  
    FOR i in 1 .. v_shuttle.count LOOP
      SELECT COUNT(*) INTO v_count FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id = v_shuttle(i);
  
      IF v_count = 0 THEN
        INSERT INTO rjm.material_objekte (objekte_id, material_id) VALUES (:P47_OBJEKTE_ID, v_shuttle(i));
      END IF;
  
      v_shuttle_ids := v_shuttle_ids || v_shuttle(i) || ',';
    END LOOP;
     
    v_shuttle_ids := SUBSTR(v_shuttle_ids, 0, LENGTH(v_shuttle_ids) - 1);
  
    DELETE FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id NOT IN (v_shuttle_ids);
  END;
  

  The Delete statement fails because the data types are not compatible. The variable v_shuttle_ids is the VARCHAR2 data type and the database column material_id has the NUMBER data type.

  Anyone has a solution to the problem (for example, casting data types) or has a better way to remove existing items from the shuttle point?

  Thank you in advance,

  Patrick

  If I understand the problem, your code should look like this:

  DECLARE
    v_count        NUMBER  := 0;
    v_shuttle_ids  NUMBER_TT;
    v_shuttle      APEX_APPLICATION_GLOBAL.VC_ARR2;
  BEGIN
    v_shuttle_ids := NUMBER_TT();
    v_shuttle := APEX_UTIL.STRING_TO_TABLE(:P47_PFLANZLICHE_HERKUNFT);
    FOR i IN 1 .. v_shuttle.count LOOP
      SELECT COUNT(*) INTO v_count FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id = v_shuttle(i);
      IF v_count = 0 THEN
        INSERT INTO rjm.material_objekte (objekte_id, material_id) VALUES (:P47_OBJEKTE_ID, v_shuttle(i));
      END IF;
      v_shuttle_ids.extend();
      v_shuttle_ids(v_shuttle_ids.last) := v_shuttle(i);
    END LOOP;
    DELETE FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id NOT IN (SELECT column_value FROM TABLE(v_shuttle_ids));
  END;
  

• Refresh only the left side of the cascade point shuttle LOV

  Hello
  
  I want to fill the shuttle point dynamically using selection LOV cascading list. but when I change to another value left and right gets refreshed.
  
  but I want to refresh only the left side, right must be the same.
  
  I want to achieve something like that
  
  http://Apex.Oracle.com/pls/Apex/f?p=579:56
  
  I want to achieve this by using Refresh before and after updating dynamic action.
  Is this possible?
  
  pls help me with this. Its very urgent.

  If you are on 4.x just used the cascade LOV Parent article (s) in the element of the shuttle

  Yes use v 4.X .and uses the parent LOV cascading item. My problem is that I want to change the elements of lov parent and cascading using different values.

  Let's say my lov elements parent has deptno 10,20,30.

  Wen I select dept 10 it should display all the emp to 10 dept. and I wil select some employees from that. then I will select dept 20 then it will show all employees of dept 20 and I will select a few PMCs from that.

  But now the prob is wen I don't change the dept No 20 of 10, the right side of the shuttle point with details emp dept 10 has disappeared. but I want that values must be ter, and should be updated by the left side.

  check out the link that I have attached in the first post. I want to achieve the same thing like that.

  Well, I looked at link above and even recreated in my demo application and added the section how it, just follow the steps

• Shuttle point - save the changes

  The shuttle point integrated is a good way to view and edit data to multiple values. If the data comes from a single line and column (delimited), using the internal order process line Fetch and automatic DML to read/write, it work well.
  
  But what happens if the data from multiple lines in a source table? Say 10 lines are selected (right hand of shuttle) off a 50 LOV. The Source of the element of the shuttle has just the query to retrieve the 10 lines and the APEX engine automatically converts multiple values into 1 delimited value required by the shuttle.
  
  But when it comes to saving the changes in the shuttle, there is no easy way to identify what has changed. Say I deselect the option 1 and select 2 new items in the left side of the shuttle. Value of the element in the session state is delimited by colon 1 string containing the currently selected values. How this translates into the ELIMINATION of 1 and 2 INSERTs necessary against the base table?
  
  I can think of to save the front-subimit value in a hidden element, comparing it to the value of after-submit and stuff like that, but that seems a lot of work. What this kind of thing done effectively?
  
  Thank you

  As the table changed with the values of the shuttle contains one column other than the PK and the shuttle update column, this can all be handled with reusable one DML MERGE statement and a utility function:

  begin
  
    merge into shuttled_states ss
    using (
    /*
      The merge source requires a set of matched pairs: the selected shuttle values
      against the corresponding values in relevant DB rows, for example:
  
      shuttle_st  db_st
      ----------  -----
      X           X       -- X is in both shuttle selection and DB rowset
                  Y       -- Y is not in the shuttle selection but is in DB rowset
      Z                   -- Z is in the shuttle selection but not DB rowset
  
      We therefore need to leave the X row in the DB unchanged, delete the Y row,
      and insert the Z row.
  
      This query should also contain other columns and values required in matching
      rows in the merge, or in inserted rows.
    */
      select
          shuttle.column_value shuttle_st
        , db.st db_st
      from
          table(string_to_coll(:p37_states)) shuttle
            full outer join shuttled_states db
              on shuttle.column_value = db.st) t
    /*
      Match conditions normally include matching PK and/or other values to get the
      relevant DB rowset, but the main requirement here is a predicate that matches
      using the DB value column from the shuttle/DB rowset pair.
    */
    on (ss.st = t.db_st)
    when matched
    then
    /*
      This is where the restriction applies. Although we don't actually want to
      update any matched rows as they are unaffected by the shuttle selection, the
      MERGE can only delete rows that have been updated. However we can't update
      any of the columns used in the match, so there needs to be at least one
      column available that can be set to the same value to mark the row as
      updated...
    */
      update
      set
          ss.state_name = ss.state_name
    /*
      ...which makes it possible to delete rows that are not selected in the shuttle.
    */
      delete
      where
          t.shuttle_st is null
    /*
      Where there's no match the value is newly selected in the shuttle and is
      inserted as a new row.
  
      (Other values required should be included in the query, or handled in a
      trigger.)
    */
    when not matched
    then
      insert
        (st)
      values
        (t.shuttle_st);
  
  end;
  

  This method uses to transform the selected values shuttle of a string delimited by two points in a set of SQL. The function provided by Oracle apex_util.string_to_table returns a PL/SQL associative array that is not appropriate for this. If it is possible to convert a string into lines purely using SQL, these methods are rather obscure and only can be reused by cutting-and-pasting. A simple function that returns a collection of standard SQL type can be used as a set of rows in a query through the SQL TABLE operator and is highly reusable:

  create or replace function string_to_coll (p_string in VARCHAR2) return sys.ODCIVarchar2List
  is
  
    l_table apex_application_global.vc_arr2;
    l_list  sys.ODCIVarchar2List := new sys.ODCIVarchar2List();
  
  begin
  
    l_table := apex_util.string_to_table(p_string);
  
    l_list.extend(l_table.count());
  
    for i in 1..l_table.count()
    loop
      l_list(i) := l_table(i);
    end loop;
  
    return l_list;
  
  end;
  

  For purposes of demonstration, this one uses the predefined sys . ODCIVarchar2List collection type. In real life, you would create your own, and of course the function would be in a package, not stand-alone.

• Need to change the com port number, but users do not have administrator rights

  Our users don't have administrator rights, however, there are a few pieces of software that communicates with the hardware using COM ports.  Since they don't have administrator rights, you may not click on advanced in the communications port to set the port to the necessary com com.

  I found reg hacks online that say will open the advanced screen to allow the com to be changed, but none that I've found work successfully.

  Can someone tell me the correct registry setting that I need to grant permission to in order to open the advanced under properties tro communications button and have the available com port number to change.

  Thanks in advance.

  Hello

  You have the computer connected to a network or domain?

  It is not possible to access advanced screen or advanced without administrator rights. I suggest you to contact the administrator of the system to help about it.

• Creation of Validation for the multiple selection list or shuttle point

  Hello
  I'm new to APEX and have questions about the best way to validate the selected shuttle items to verify that they exist in the sys.dba_roles table before submitting. The shuttle point uses a static LOV. I would like to than the error message to display when there is no such thing as a role selected in the element of the shuttle in the sys.dba_roles table.
  
  Using version 3.2 of APEX
  DB version 9.2.0.8.0
  Internet Explorer version 6
  
  I tried to create a validation step level about to shuttle P3_ROLE using SQL EXISTS when you press the button SUBMIT. I know that when argued that the shuttle point returns the selected values in a single string delimited by a colon. I use the APEX_UTIL. STRING_TO_TABLE to convert values selected in a table.
  
  CODE HERE
  declare
  l_selected APEX_APPLICATION_GLOBAL. VC_ARR2;
  number of l_num;
  Start
  l_selected: = APEX_UTIL. STRING_TO_TABLE(:P3_ROLE);
  BECAUSE me IN 1.l_selected. COUNTY
  LOOP
  Select 1 from l_num of sys.dba_roles where role = l_selected (i);
  END LOOP;
  end;
  
  This is the error ORA-00928: lack of SELECT keyword
  1006 - ERR error in the validation routine.
  
  Any advice? Thoughts? Thank you.

  Hello

  Your code is PL/SQL block. You cannot use this type of validation with your code.

  Try to change the body type of the function that returns the error text and
  code for this one

  DECLARE
    l_selected APEX_APPLICATION_GLOBAL.VC_ARR2;
    l_num NUMBER;
  BEGIN
    l_selected := APEX_UTIL.STRING_TO_TABLE(:P3_ROLE);
    FOR iIN 1..l_selected.COUNT
    LOOP
      SELECT count(1) INTO l_num FROM sys.dba_roles WHERE role = l_selected(i);
      IF l_num = 0 THEN
        RETURN 'Role not exists';

• OfficeJet 6500 e709: prints w / scale on the left margin and does not print right side of the page

  Prints with a wide margin and does not print the last 2 "or 3" on the right side of the page. This occurs even when the value of the left margin to little or none.

  HP trouble shoot said there is nothing wrong and test page prints fine.  Then back to the problem so try to print.

  HI @philg2,

  I see your thoughts produce a wide margin left and right of the page is cut off. What program are you printing from, and this occurs when you print from all programs or just a particular program?

  I see your post that this is not happening when you print a test page, so I think the problem is somehow related to the driver or program that you use. Let's start with the HP print and Scan Doctor is a free utility (tool) that allows to quickly resolve problems printing, scanning and connectivity, including but not limited to:

  • Connectivity:

    USB: Check that the USB connection from your computer to the HP product works properly.

    Network: Verifies that the network connection between your computer and your network is working properly.

  • Device Status Test: checks the errors of the device, such as paper, paper jams, stands transport and paper issues and provides instructions to resolve the error.

  • Driver: checks the driver missing or corrupt files.

  • Device Manager: check the problems in Device Manager that could prevent printing.

  • Device online: check if the product has been suspended or put in offline and then sets the State back in line if necessary.

  • Print queue: checks and clears pending print jobs in the print queue (a newspaper for printing waiting to print).

  • Port Match: check the port settings for the HP product.

  • Device conflicts: check the conflicts with other drivers, such as the other brands of printers.

  • Ink issues: check the cartridges and the ink levels for issues that affect the print quality.

  • Print settings: check and adjust the print quality settings.

  • Test print: print a test page for the assessment of the print quality and provides options for cleaning and if necessary print head alignment.

  • Scan tests: check the scanning mechanism, drivers, and registry entries.

• Windows Explorer - right column to automatically display the left folder?

  Simple question for Windows Explorer: is it possible for Win7 64 bit to display in the column on the right immediately which is highlighted in the left column?  (Like most of the any Manager files on the planet!)  I guess they try to minimize the work that the program does stuff that shows only the user didn't need.  When the user arrives at its destination they press enter or space to display the content.  I understand your point and minimize the workload for the program.  Stupid of course in real life, is not an option.  As usual, Microsoft, like most software companies think people want to think for them.  Not the case.  Unless of course I missed the 'show content immediately' option somewhere.  Its got to a point where you cannot assume a sense of almost any software company.  They all try to think for you, you Lasso in their way of doing things.  Guess it helps in the Department of bugs, but makes for very unhappy and frustrated users.  Or if you are a fool, do you think that the system is perfect, because it assumes that all your decisions for you.  Society is reflected in many ways in the design of software.  Doesn't look like good people.  People seem to become lazier and lazier or they become busier and busier and can not do even the simplest decisions.

  He agreed with the request of the customer.  Visitors don't like the record, in that they were to change until they had highlighted that they really wanted to enter.  It was particularly embarrassing when put customers highlight a network location that takes several minutes to connect or charge (heaven help you if this was a corporate backup tape location).    It was also a common complaint that it was incompatible (derivative of something is not supposed to cause an action occurs in a part any system: only by clicking or by selecting with button enter should).

• Finder - right scrolling automatically snaps back to the left

  Hello

  I use Yosemite on a Mac Book pro. Recently, I noticed a problem with my finder. I have 'column view' enabled. When I scroll to the right to see the items more far in my tree, rather than stay where I scroll finder window cling all the way back to the left, showing the folders at the root of the drive. So, I actually don't see not all folders deeper in my directory structure.  I can't understand why this is happening. I hope someone can help out me!

  UPDATE: I discovered another problem which could be related. If I go to any program - safari, word, etc. and scroll all the way to the right, if I move the mouse over the program it will automatically scroll to the left. If I point the program, scrolling stops.

  Thank you!
