How can i validate attribute(timestamp type) enter date day is not sunday.

hi All,
problem is that i want to validate timestamp type attribute. when user select a date if the date day is sunday than error message
show to user.
can i do this with groove expression.

You can add a script validation to the EO attribute and use an groovy expression like
def d = newValue;
println d.day;
return d.day != 0;
      I only tested this with a date but it should work with a timestamp too...

    thanks !

    The tangent ist the derivative of the curve in that point. You can try to use a numerical derivative vi or keep it simple an approximate with a line through the adjacent points.

  • How can I use table control to enter data

    Hi all,
    I want to use table control to enter data, instead of using textboxes.
    So that the user can enter many data at once and just click the save button at the end of the work, only one click.
    How can I use the table control at this context?
    Thanks.
    Deniz.

  • How can I find out what type of data is being sent over one of the phones on my plan?

    I have a few phones under a shared family plan.
    I wanted to know what type of data is being sent over them, wether this is VOIP, Streaming Audio or Video.

    I think the only way you can find out is if you look at the device itself.

  • How can i validate(compare) two date type attribute in EO.

    Hi All,
    jdev version 11.1.2.1.0
    i have created one EO where two date type attribute ToDate and FromDate now i want to add validation rule.
    which validate that difference b/w ToDate and FromDate not more than 3 month.
    How can i validate this?

    You can create script expression
    Something like
    if((toDate.getTime()-fromDate.getTime())/(1000 * 60 * 60 * 24)>30)
      return true;
    else
      return false;-Arun
    P.S : Above example calculates based on number of Days (30). If you want 3 months, you need to put a logic - Simply 90 days? What about the months with 31 days and 28/29 days? etc.

  • How can i validate input number into a Field of  type char in oracle form?

    hi.....
    can any one help me.....please...!!!?!!
    How can i validate input number into a Field of type char in oracle form?

    i have tried doing that, but still the field except numbersthere was an error in that code. it should have been
    var_num:=to_number(var_char);however, it appears that you want the entry NOT to be a number. if this is the case then try
    begin
      if to_number(:block.item) = 0 then null; end if;
      message('The entry cannot be numeric');
      raise form_trigger_failure
    exception
      when value_error then
       /* this is where you put the code you want to be run when the
          entry is non-numeric */
    end;

  • How can i restrict the Expenditure Type values at a specific OU ?

    Dear Guys,
    I would like to ask about the Expenditure Types,
    I have implemented two projects for different Operating Units ,
    when navigating to any Projects responsibilty,and navigating the Expenditure Type field
    the values exist are all the values implemented across the OU not the values entered at this OU
    How can i restrict the Expenditure Type values at a specific OU
    Regards
    Amr Hussien

    Hello
    When you set up a project there is an option called Transaction Control.
    This option allow you to list the allowed or restricted elements of costs for the project.
    You may enter the transaction control on a project template and that will be copied to any new project.
    The cost elements may be expenditure types, expenditures categories, suppliers, employees, etc.
    In your case, I suggest to set up specific project templates for each operating units. On each template enter the list of allowed expenditures types for that OU.
    Doing so, the system restricts users from entering any expenditure item, supplier invoice, purchase cost etc, against an expenditure type, which is not allowed.

  • How can I validate a date field in Portal Forms

    I have a date field in portal forms that I want to perform validation on to make sure it's in the proper format before being accepted (mm/dd/yyyy). How can I validate against that field?

    Hi Ben,
    I took the time to test and revise. This is code that will validate a date entry (format MM/DD/YYYY). Just paste this in the "Before the start of the form..." window of the Additional PL/SQL code section of the form. Then add validateDate(); into the onBlur event window of the field in question. Replace the CYCLE_END_DATE with the field name in question.
    HTP.P('
    <SCRIPT LANGUAGE=javascript>
    function validateDate() {
    var ddObj;
    var mmObj;
    var yyObj;
    var day;
    var mon;
    var year;
    var field_val;
    var field_name;
    for (var j=0; j < document.forms[0].elements.length; j++) {
    field_name = document.forms[0].elements[j].name;
    field_val = document.forms[0].elements[j].value;
    if (field_name.substring(field_name.indexOf(''DEFAULT.'') + 8, field_name.lastIndexOf(''.01'')) == ''CYCLE_END_DATE'') {
    var delimPos = field_val.search(/\//i);
    if (delimPos < 0)
    alert(''Invalid date entry! Please enter in MM/DD/YYYY format. '' +
    ''e.g, Dec 21, 2003 would be entered as 12/21/2003'');
    else
    if (field_val.length != 10)
    alert(''Invalid date entry! Please Please enter in MM/DD/YYYY format. '' +
    ''e.g, Jan 1, 2003 would be entered as 01/01/2003'');
    else {
    month = field_val.substring(0, field_val.indexOf(''/''));
    day = field_val.substring(field_val.indexOf(''/'') + 1, field_val.lastIndexOf(''/''));
    year = field_val.substring(field_val.lastIndexOf(''/'') + 1, 10);
    /* Need to subtract 1 from value because in Javascript, January begins with 0
    and ends with 11 for December */
    month = month - 1;
    ddObj = new Date(year, month, day);
    mmObj = new Date(year, month, day);
    yyObj = new Date(year, month, day);
    if (ddObj.getDate(ddObj.setDate(day)) != day)
    alert(''Invalid day!'');
    if (mmObj.getMonth(mmObj.setMonth(month)) != month)
    alert(''Invalid month!'');
    if (mmObj.getYear(mmObj.setYear(year)) != year)
    alert(''Invalid year!'');

  • How can i validate an untouched cell and change bground color if error

    Hi ,
    three questions
    1. I can validate data in cells in setValueAt method but the cell data will be validated only if user click on that cell.
    how can i validate another cell if user does not even touch it.
    2. and if error how can i change background color.
    3. i have JTextField for column as cell editor/renderer. To change the data user have to double click on cell. How can I make it to click once to edit the value in the cell.
    Thanks in advance for help.

    how can i validate another cell if user does not even touch it.
    Why would you want to validate a cell if a user doesn't change it?for example user clicked Add row, and i added a row in the table with blank information...so .all cells in the new row have blanks, so if user does not enter the data in the second column... which he did not touch...i want to catch it and produce error
    How can I make it to click once to edit the value in the cell.
    Something like this:
    DefaultCellEditor dce = (DefaultCellEditor)table.getDefaultEditor(Object.class);
    dce.setClickCountToStart(3);Thank you..

  • How can I validate my XSD programatically ?

    Hi,
    I know how to validate XML against an XSD. But how can I validate an XSD itself? i.e Programatically press the "validate" button in XML Spy.
    I have tried validating it against http://www.w3.org/2001/XMLSchema.xsd . But this does not work for imports. i,e MySchema.xsd imports CommonSchema.xsd and uses CommonSchemas element definitions.
    When I validate against XMLSchema.xsd it does not check the imports.. i.e i can delete an import statement and its still valid - and in this case it obviously shouldnt be.
    Anyone any ideas?
    Cheers,

    Hi Caffaine,
    sounds like a difficult problem... I tried to do something similar to this a few years ago under Java 1.3, and I can tell you that you'll have a couple of problems.
    1) ResourceBundles are a type of cache, so the one you load first is the one you are stuck with for the remainder of the program execution. The only ways around that AFAIK is to either author your own non-static ResourceBundle, or to have the user re-execute the client every time they want to change locales (neither of which is particularly appealing). Not sure if anything in Tiger has rectified this, but I don't think it has.
    This also means that your server will be stuck in a certain locale. Probably the best thing to do would be to write your clients so that all information heading back to the server heads there in Unicode, so that you're dealing with a common encoding on the server side. This means no bytes or chars. Strings would be the thing to use.
    2) AFAIK, Java has no way of programatically changing the Windows input locale. Though if I am wrong, someone please correct me!
    Hope that helps!

  • How can i validate items in java

    hi....
    how can i validate items in java....so that user can not type in characters
    in the place of number????
    please help?!?

    Hope u know getText() method returns string
    i.e text1.getText() returns string.
    U need to convert the string to integer with integer class. Go
    to the documentation to search for it.
    Then attach a conditional statement stating if not numeric
    , then not valid. if u have little knowledge of java, u will understand it.
    Otherwise, wait till tomorrow bcos I'm late for xmas carol.

    It'll be complicated in pure SQL, as you'll have to parse out day, month and year and then validate the day against the month and year bearing in mind the rules for leap years.
