Validation of the name and nonalphanumeric characters Unique

Hi all

How to make the name Unique and Non Alpha-numeric characters Validation?
Name must be unique and allow only alphanumeric characters.

Where do all validations? In EOImpl or any other file?

Help, please

Thank you

Here are the steps that you must perform to ensure the double necessity of employee names not entered by the user.

First create a VVO in your schema.server (that of the OT) package with the following query. Generate the files VVOImpl and VVORowImpl.

select full_name
from fwk_tbx_employees
where full_name =:1

Now, add this to your VAM VVO means instance gives him.
Now open the VVOImpl and write below the code to execute the query based on the new name entered by the user

    public void initQuery(String name)
    {
      setWhereClauseParams(null); // Always reset
      setWhereClauseParam(0, name);
      executeQuery();

    }

Now open your entity class Expert and add under method inside

   public boolean isEmployeeNameExists(String name)
   {
     boolean isExists = false;

           // Note that we want to use a cached, declaratively defined VO instead of creating
           // one from a SQL statement which is far less performant.

     EmployeeNameVVOImpl employeeNameVVO =
       (EmployeeNameVVOImpl)findValidationViewObject("EmployeeNameVVO1");
     employeeNameVVO.initQuery(name);

     // We're just doing a simple existance check.  If we don't find a match, return false.

     if (employeeNameVVO.hasNext())
     {
       isExists = true;
     }

     return isExists;

   }

Now you must call this method in the expert class of setter of EOImpl to name.so, open the EOImpl file and go to the name setter method

      if ((value != null) || (!("".equals(value.trim()))))
      {

        EmployeeEntityExpert expert = getEmployeeEntityExpert(getOADBTransaction());

        if (!(expert.isEmployeeNameExists(value)))
        {

            throw new OAException("Duplicate Employee Name", OAException.ERROR);

                  }
      }

Don't forget to write the above code setAttributeInternal.

I hope that helps!

Let me know if you have any queries in it.

Thank you
AJ

  • Send the name and the value of the control to Subvi

    Hi all

    I am trying to send the names and values of the controls to a Subvi.

    I know that I can check out the name and the value of the control by using a property node, but I was looking for a way to make is easy for the programmer to use.

    I think some sort of bundle function, it records the name and the value of the control, but I would like the programmer to be able to connect a random number

    controls to the Subvi without having to specify the number of controls Anywhere.

    I know there is stuff in labview configuration file, but it seems a bit more complex, so what I want to do.

    Also, I know that I can use the OpenG toolkit, but I will not use additional LabVIEW modules, as this VI may run on several different computers.

    I hope I made my problem clear enough!

    Good day

    Concerning

    Tommy

    What, creating an array of references to the command.  On the hand, you will need to fill the table with control references that you want to send to the Subvi.  In the Subvi, use a loop For with indexing to get every reference, and then use the nodes property to get the name and value.

  • Get the name and the data type into an object?

    Hello

    I would like to know if there is a way to get the names and the types of data encapsulated in an object of labview?

    For example, let's say I make a simple object, called myObject to be commonplace, with private data: myObjectName (string), myObjectValue (int 32) (etc.)

    So, how to build a method to return the type of the data of myObjectValue, or infact back the names and types of all data in the object field, which could be a lot?

    Windows Mail? Microsoft Mail has not been around for 15 years.

    To use the functionality of the BCC (Blind Carbon Copy), in a new message window, click View | All headers and type the addresses separated by a; Or: Click the button to. You will see your list of contacts and the choice to put them in the To, CC, or BCC field. Click on an address, and then click BCC to add it. Repeat for all of the contacts you want. (Note: most of the providers have limits as to how many emails, you can send a time a. 25 ~ 100 is common, but it varies).

    Put your own address in the box to. That's the only name/address that any recipient will see. If you leave the field empty, some people may not receive e-mail because of message rules they put in place, or restrictions imposed by their ISP.

    You can also make an entry in the address book using your e-mail address, but put something like the mailing list in the area of the display.

  • Virtual PC/XP Mode is asking me my name & the password. I think it says XPMUser and wants to answer me with a password. I want to change the name and create a password. I have never created a.

    I have not created anything yet he keeps asking for a password and display name is XPMUser, I believe.  How I can change this option to create a password also.  My file is listed as XPMUser under.   c:/Documents and Settings/XPMUser I have this file.  Who has my name there instead and if so how to change the name and create a password?

    Thank you

    When you install Windows XP Mode, it automatically creates a user named XPMUser account.  If you want to use a different name:

    1. log in as that of XPMUser.
    2. create a new computer administrator account with the name that you want.
    3. close XPMUser.
    4 log in to the new account and create a password.

    You can then remove the XPMUser account if you wish.

    Hi David,

    It's because you have installed CloudFogger, which protects your files in enrcytpt them to ensure safety for DropBox or GoogleDrive. Probably, you have not installed the program, that's why it shows all files with the extension .cfog I you Explorer.
    Re-install the program and you connect to your account back on your files.
  • Windows 7 F2 selects the name and extension

    where is the setting in Windows 7 that allows me to select the complete with extension when file name I F2 (rename) it.

    I think I see a question about when the first time I used Windows 7

    What you see is the default behavior in Windows 7.

    As Shawn b. Keene points out in his post on the topic below, it prevents users from changing the extension which can lead to the file will not be opened by the appropriate program. I realize that for a more experienced user like you maybe it's not a problem, but for the average user or novice, this could cause problems.

    As a workaround, it suggests to use the keys Ctrl + A or SHIFT + end immediately after pressing F2. It may not be perfect, but it does not work.

    When you rename a file highlights only the name and not the name extension.

  • srvrmgr syntax: How can I create subsystem named with the name and Description of the values?

    Looking through the library, he did discuss are of syntax that allows you to include the value of name and the named value of the Description of a subsystem/Profile Configuration.  In the screenshot, the circled values were created with the server online order Manager.

    NamedSubsystems.gif

    On the other hand, pouvez create a definition of the element with a name (full name) and a Description.

    For CompDef, it works:
    create the CompDefTest1_enu component definition for the type of component AppObjMgr component fins group run mode interactive full name 'Test Comp Def Test 1' description 'Test 1 CompDef Manager object.

    For named Subsytem, it does NOT work:
    create named subsystem Test5 subsystem EAITransportDataHandlingSubsys full name 'Test 5' description 'Test 5 Description'

    Someone can tell me if there is a good for a named subsystem, syntax to include the name and Description of the values in the command line, or is the only way to create it manually in the UI?

    Hello

    I spent reviewing aid to create the order in srvrmgr, it does not give the full name and description as parameters for the creation of subsystem. However, as you noted these settings are available for creating components definition:

    srvrmgr > help to create

    Create {component group | compgrp}

    [full name: ]

    [{description | desc} ]

    create {definition component: compdef}

    for {component type | comptype}

    {Component group | compgrp}

    run in mode {batch | interactive | background}

    [full name: ]

    [{description | desc} ]

    [with [ param =[, =...]]]

    [[fixparam =[,...]]]

    create the subsystem named for

    subsystem with = [,...]

    Shelf also has an example of creation of subsystem that doesn't include no description, name and first name:

    http://docs.Oracle.com/CD/E14004_01/books/StoreFwdMsg/StoreFwdMsg_InstallConfig14.html#wp1351472

    In this case I suggest that allows you to create a ticket on My Oracle Support to confirm this srvrmgr does not support the creation of a new subsystem with the full name and description settings and request an enhancement for these settings include request in create statement for new subsystems when using srvrmgr.
