In the form of oracle do not allow the cursor to move forward if the value is not entered

I need to change an existing form in which the cursor should not go forward if no value is entered in the field. There are a lot of articles for this block. If no value is entered for a particular ITEM, then the cursor must not move forward by pressing the Tab key.
Please let me know what property must be set for this thing to work.

Suppose I don't want the cursor to return to the first field by pressing TAB after coming from the last field... what to do... ?

There is more than one thing you could do, but it depends on exactly how you expect the form to work.

A very simple way to do this would be to create a trigger KEY-NEXT-POINT on the last item in your building.

   -- KEY-NEXT-ITEM trigger
   NULL;

Tab after the last item would then be disbabled.

Again, this depends on exactly how you want it works.

Tschüss! :)

    Hi friends,

  • Case of event Structure to manage the value between

    I put in place a structure of the event to enter data in a multicolumn listbox.  I wanted to use a table, but it was difficult to place symbols in the first column; even using the odd fonts (Webdings, etc.) to get check marks, x, etc...  I don't want the user to change some of the columns, so a MCL with a structure of the event to detect user input works well in the test code.

    When the user clicks on a cell in the LFA, then I place a transparent control chain on the cell of the same size, so the user, it seems that they enter data.  I pre-fill the chain with the existing content of the cell control and site selection at the end of the string.  After you enter a string, the control of transparent string is moved outside the LFA, so all the clicks of the mouse in the LFA are always detected.  It all works very well.

    If the user changes the value and press 'Enter' or click on the button Enter text under the file menu check box, the structure of the "Change value" event triggers then.

    If the user keeps the same value and presses 'Enter' then the structure of the 'Touch Up' event where ScanCode = 28 detects the press 'Enter '.

    However, if the user wants to keep the same value and presses the button check box on the file menu and then the structure of the event does not detect it.  I added a bunch of advanced control of the chain, but if the user moves the mouse away from the control and then the tip appears only for a few moments.

    Some of my users are used to click the box to enter the channels, so I'd like to understand how to handle this event.

    What can I add to the structure of the event to detect user maintaining the same value by clicking the checkbox?

    Thanks for any advice.

    Leif Kirschenbaum

    P.S. I'm using LV 7.1 because my startup employer cannot justify the money to upgrade right now.  Yes, in more modern versions are nodes property to indicate the line & column clicked in a MCL, but I don't have access to it, so I use the position sizes and the row/column of MCL up/left to determine what cell they clicked in.

    You could hide the toolbar of the VI during the race, this disables the option click on the button "enter".

    Or you can run a small loop to see if the string still has key-focus, I discovered that when you enter the main focus is removed from the control of the chain.

  • 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

  • Calculate the value based on the selection of the checkbox

    People from g ' Day,.

    I have myself a little stuck on a job that I have here, this javascript Gets the better of me.

    The idea is that this script takes the total sub and adds a surcharge for credit card (in percentage) based on a selection of the checkbox, then spit out the value to be entered in another field.

    If someone could have a quick look over what follows and let me know where I went wrong, it would be appreciated.

    ---

    Subtotal var = this.getField("SubTotal").value;

    var mastercardTick = this.getField ("MasterCard");

    var visaTick = this.getField ("Visa");

    var amexTick = this.getField ("Amex");

    Var extra = this.getField("CreditSurcharge").value;

    card credit var = this.getField("PayCredit").value;

    If (creditcard.value = 'Off') {}

    Event.Value = 0;

    } else {}

    If (mastercardTick.value = 'Yes') {}

    overload. Value = (1,2 / 100) * subtotal.value;

    } ElseIf (visaTick.value = 'Yes') {}

    overload. Value = (1,2 / 100) * subtotal.value;

    } ElseIf (amexTick.value = 'Yes') {}

    overload. Value = (3.75 / 100) * subtotal.value;

    } else {}

    Event.Value = 0;

    }

    }

    ---

    For lines like these:

    overload. Value = (1,2 / 100) * subtotal.value;

    If it should not be as:

    Event.Value = (1,2 / 100) * subtotal.value;

    The variable supplement is defined at the beginning of the script to the value of the field, so the surcharge.value parameter is not any sense.

  • Oracle apex 5.0: not update the values in the Collection.

    Hello again,

    I have a problem in IR where content comes from the collection query.

    Now the question is when I update the value of the column in the report and click on the custom button, that it will update the value of collection and insert the updated values of the collection member in another table that works well according to my condition, but when I will apply to any word in the search bar (say books in order not to update the values of books) and tries to update the value as a result of research above requirement does not work I mean the collection is not updated.

    All of the Suggestions!

    Thank you

    The "coll update" process fails with a ORA-01403: no data found error. This happens in line 11 because of the access attempt to the wwv_flow.g_f01 using the variable array subscript c who has been incremented beyond the size of the table, which is now smaller because of the IR filter applied.

    begin declare
      c pls_integer := 0;
    begin
    for c1 in (
      select seq_id,c001 from apex_collections
      where collection_name = 'MATRIX2'
      ) loop
    c:=c+1;
    apex_debug.message(c);
      apex_collection.update_member_attribute (p_collection_name=> 'MATRIX2',
      p_seq=> c1.seq_id,p_attr_number =>'2',p_attr_value=>wwv_flow.g_f01(c));
    
    end loop;
    end;
    end;
    

    I agree with fondant tabular forms on interactive reports, but you can meet your requirement as follows. In your application, see page 2.

    1 Add a column of form element hidden IR containing the sequence number of collection:

    select
        c001 col1
      , apex_item.text(2, c002) col2
      , apex_item.hidden(1, seq_id) seq
    from
        apex_collections
    where
        collection_name = 'MATRIX2'
    

    2 place the question of the hidden form in the report using the COL1 Expression HTML attribute:

    #COL1##SEQ#
    

    3. change submit to the process if it is driven by the subject table, not the existing collection:

    begin
    
      for i in 1..apex_application.g_f01.count
      loop
        apex_collection.update_member_attribute(
            p_collection_name=> 'MATRIX2'
          , p_seq=> apex_application.g_f01(i)
          , p_attr_number => '2'
          , p_attr_value=> apex_application.g_f02(i));

    Hello

    personally, I release the cell object as soon as the value is written in a variable and not in a procedure that closes the file. Note that there are many cells read (so you should relase each cell individually).

    The publication of the application is such:

    Procedure CloseApplication is

    Begin

    CLIENT_ole2.release_obj (Workbook);

    CLIENT_ole2.release_obj (Workbooks);

    CLIENT_ole2. Invoke (application, 'Quit');

  • I have a HTML5 form that sends a null (%) if the user does not have a choice. It works fine, but I get an error of W3c on the value of '% '. Is there another way to send a NULL value?

    I have an HTML5 form that allows the user to select 1 of 6 provinces of Costa Rica. If they do not select a Province, I use php code to send a NULL value and the other selections research of the form looking for all Provinces. If they choose a province, we are looking for database records that are found in this province.  Currently I use the value = '%' as the selected value if the user does not have a choice. It works and looks in all provinces, but I get an error of W3c checking on the value = '% '. Y at - it another way to send a NULL value.

    whenever I call my forms oracle from internet explorer 6, it still ask me to download jinitiator before the form can be opened and when I download, web forms pages display just a blank page while outside.
    my forms is oracle 10 g 2 on OEL5
    my database is oracle GR 11, 2 on OEL5
    My OS is winXP on oracle VM VirtualBox.
    the version of java that I use is 7.0.170.2.

    the funny thing is that I could call another form from another machine OEL5 on this OS (winXP) even, but when I call this particular application, the question comes up.

    Please what could be the problem?

    Thanks in advance

    As'salamualikum Abdur Rahman,.
    Because you are using / 10g application call is not supported JRE version 1.7_XX. You must install JRE 1.6_XX. You can download it from http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html#jre-6u39-oth-JPR

    Do not forget before you install 1.6_xx, uninstall the JRE version.

    but do not forget formsweb.cfg must configure for JRE.

    Another question, you said, you are able to call another application without error. Please check that the configuration, what is for?

    Hello. I have this code to send a warning message that the user is updating a file on my my form of Oracle database table.

If I submit this code in SQL Plus, she runs and I receive the email as expected.

    p_begin_date and p_begin_date (why 2 times start date? in any case). are concattenated in a varchar2, so a type conversion occurs; the date format used is the nls_date_format of your session. If this will result to

    begin TTMS.dropperVacationemailurl_new (1234,01-FEB-11,01-FEB-11); end;
    

    now take this block and run it in SQL * more. I can see miles it won't work, because the date data types that you pass are not yet passed as strings.
    It might work, if you pass them as strings:

    begin TTMS.dropperVacationemailurl_new (1234,'01-FEB-11','01-FEB-11'); end;
    

    but then I say I just change the nls_date_format of my session and break your code, because the implicit conversion from varchar2 to date will fail.

    the very ugly solution for this should be

    job_action => 'begin TTMS.dropperVacationemailurl_new ('||p_dropper_id||',to_date('''|| to_char(p_begin_date,'dd-mon-yy')||''', ''dd-mon-yy''),to_date('''|| to_char(p_begin_date,'dd-mon-yy')||''', ''dd-mon-yy'')'); end;'
    

    If you have a tank that is converted to a date that you go to the external procedure which then gets converted to a tank which then gets converted to a date once again. My head hurts. If simply insert you dates into a table and select the dates in dropperVacationemailurl_new instead of 10000 conversions and pass them you wouldn't make 10000 converts and don't care the date format.

    see you soon
