How to access the structure of a dynamically created context node/element

Hi All,
in method wddoinit I have added a context node and some attributes
lo_node = wd_context->get_child_node( name = wd_this->wdctx_instructors ).
lo_node_info = lo_node->get_node_info( ).
lo_node_info = lo_node_info->add_new_child_node( name                  = 'OCCUPANCY'
                                                   is_mandatory          = abap_true
                                                   is_multiple           = abap_false
                                                   is_multiple_selection = abap_false ).
      lo_node_info->add_attribute( ls_attr ).
So far, I have node INSTRUCTORS (0...n) with a subnode OCCUPANCY (1...1)
In the supply_method of INSTRUCTORS I would like to fill the instructors node and the OCCUPANCY subnode.
The thing is I do not know the structure of the dynamicaly created subnode OCCUPANCY there. How can I get a description of this node (that, what in non-dynamic programming would be wd_this->element_occupancy...)??
THANKS,
Johannes

...I got this one solved by myself...
I simply added this coding:
lo_node_info = lo_node->get_node_info( ).
lt_attributes = lo_node_info->get_attribute_names( ).
This appers to be enough information to be good to gogo
Thanks anyway.

How to delete a dynamically created context node ?

Hi
I have created a context node dynamically and have added the check boxes to the node.
But when i am refreshing the page it is giving me the following excepiton:
com.sap.tc.webdynpro.progmodel.context.ContextException: DataNodeInfo(DwdReportView.Person): duplicate name for attribute attr1
I am writing the following code in wdDoExit() method so that the node is invalidated and all dynamically added nodes and attributes are destroyed from the metadata.
The code is :
     wdContext.getContext().reset(false);
or
     wdContext.getContext().reset();
or
                     wdContext.nodeName().invalidate();
I have tried all the above mentioned code snippets but it is still giving me the same exception.
Please help me resolve this issue.
Thanks in advance.
Regards
Shaily

Shally,
A better forum to place your question is the forum.
To your question: the wdDoExit() method is only called once i.e. when the view is destroyed from memory. Just like the wdDoInit() mehtod is called only once at initialisation of the view.
Try refactoring your code, so that upon initialising of your context, the old version of it is removed.
Hope this helps.

Alain

How to access the value of a dynamic checkboxes

Hello,
I have a userform with a dynamic set of checkboxes.
Set chkBox = Me.Controls.Add("Forms.Checkbox.1", "Checkbox_" & counter & "_" & i)
I'm giving the name of each checkbox multiple parts because there will be multiple rows of checkboxes.
How can I know if checkbox_1_1 is checked or not?
I have tried
For Each cont In Me.Controls
If cont.Name = strCtrlName Then
'cont.Value doesn't exist
End If
Next cont
The value property is not showing up.
Thank you for any help

Maybe you've got your strCtrlName wrong, this worked for me
Private Sub UserForm_Initialize()
Dim i As Long
Dim counter As Long
counter = 5
Dim chkBox As MSForms.CheckBox
For i = 1 To 3
Set chkBox = Me.Controls.Add("Forms.Checkbox.1", "Checkbox_" & counter & "_" & i)
chkBox.Left = 9
chkBox.Top = i * 20
chkBox.Caption = chkBox.Name
Next
End Sub
Private Sub UserForm_Click()
Dim i As Long
Dim counter As Long
counter = 5
Dim chkBox As MSForms.CheckBox
For i = 1 To 3
Set chkBox = Me.Controls("Checkbox_" & counter & "_" & i)
s = s & i & "=" & chkBox.Value & " "
Next
Me.Caption = s
End Sub
Paste the above into an empty userform and run it. Tick a couple of checkboxes and click the form.
Maybe look into WithEvents in a class module to trap and act on checkbox changes in real time.

ADF 11g + How to capture the value of a dynamically created input text box

Hi All,
I have a requirement where, on selection of the value in a drop down, the input text boxes need to get dynamically populated on the JSPX page. I'm able to bring this functionality, and it is working fine.
But the challenge right now I'm facing is that, how to read/capture the value entered in those dynamic text boxes on submission of the page. Please help me in getting this resolved.
Below is the code snippet I'm using for this.
// Clearing the existing input fields in the Panel form
while (pf100.getChildren().iterator().hasNext()) {
pf100.getChildren().remove(pf100.getChildren().iterator().next());
// Creating the new fields based on the number of IP addresses selected
for (int i = 0; i < iIPAddress; i++) {
RichInputText pcPreferredDomain = new RichInputText();
pcPreferredDomain.setLabel("Preferred Domain / Hostname for Desktop PC/ Laptop - " +
(i + 1));
pcPreferredDomain.setColumns(40);
pcPreferredDomain.setId("pcpfdomain" + (i + 1));
pf100.getChildren().add(pcPreferredDomain);
Thanks All in Advance,
Thanks & Regards,
Dharmathej M

As per your method, you are creating the RichInputText components as local variables.
What happens when you are creating them as class level variables in the managed bean, if you do so, you can refer to the values of the UI components in the actionListener/action code for the command button in the managed bean
sample:
public class ManagedBean{
RichInputText [] pcPreferredDomain;
public ManagedBean(){
// Clearing the existing input fields in the Panel form
while (pf100.getChildren().iterator().hasNext()) {
pf100.getChildren().remove(pf100.getChildren().iterator().next());
pcPreferredDomain = new RichInputText[iIPAddress];
// Creating the new fields based on the number of IP addresses selected
for (int i = 0; i < iIPAddress; i++) {
pcPreferredDomain[i] = new RichInputText();
pcPreferredDomain.setLabel("Preferred Domain / Hostname for Desktop PC/ Laptop - " +
(i + 1));
pcPreferredDomain.setColumns(40);
pcPreferredDomain.setId("pcpfdomain" + (i + 1));
pf100.getChildren().add(pcPreferredDomain);
Thanks,

How to access the ORACLE APPS table structures from SAP

Hi Experts,
How to access the ORACLE APPS table structures from SAP? Is it possible from SAP?
Thanks in advance
Thomas

Hi Silviya,
you can access this database using a technique called DB Multiconnect - sometimes written as multi-connect.
Search the SAP documentation and notes for this term and you will find how to do it.
Essentially you configure the remote database connection via transaction DBCON.
If your SAP system is not running on Oracle you will need to install the db-specific kernel files for Oracle along with the Oracel db client software - SQL*Net.
Then you can access the Oracle database from ABAP using native-SQL. It works a treat!

In VB Programming code -- How to access the formula for suppressing a field

In VB Programming code -- How to access the formula for suppressing a field
I am using Crystal Reports 2008 v1
Using VB code, I am attempting to modify a Crystal Report before exporting it into a PDF format and then displaying it on the Web.
My problem is that I am unable to access the formula used to dynamically suppress a field.
The following code is working:
mySections = rd.ReportDefinition.Sections
For Each mySection As CrystalDecisions.CrystalReports.Engine.Section In mySections
   ' myFieldToChange is a String set to the text of the field I need to adjust the Suppression
   iloop = 0
   For Each RecObj As CrystalDecisions.CrystalReports.Engine.ReportObject In mySection.ReportObjects
           If mySection.ReportObjects.Item(iloop).Name.ToLower = myFieldToChange Then
               myTextObject = CType(mySection.ReportObjects.Item(iloop), CrystalDecisions.CrystalReports.Engine.TextObject)
               myTextObject.Text = "new field text goes here"
               mySection.SectionFormat.EnableSuppress = True
               ' Here is where I want to change the formula for the Suppression
            End if
            iloop = iloop + 1
    Next
Next
I can not find any reference to the actual suppression formula in the SDK help file.
Note, the EnableSuppress can be set to True for False, but if there is a formula for dynamic suppression, the True or False value is overwritten. The results of the formula determine the suppression.
Is there a way to reference this formula. I know that I can put on in using the Crystal Report Designer software, I need to modify this formula using VB code and the SDK.

Hello, Mark;
If you are using the ReportDocument object you do not have access to the Conditional Suppression formula. You can get around it by using a formula field in the report for the supression and then using the FormulaField code to change it at runtime.
If you want to change the supression condition directly at runtime you need to use RAS and the ReportClientDocument.

How to get the extension Info from firefox? Do we have any firefox API to communicate with the browser? I couldnt see the HTML of the widget displayed in the toolbar how to access the widget using JS or any way

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(
Have u ever tried to do some things like this?

How to populate the combo boxes that are created dynamically in jsp

Hi,
I am using JSP.
I am creating combo boxes dynamically (based on the num selected by the user). These dynamically created combo boxes need to have A-Z as options (each box) . Now, when the user chooses the option A in any of the combo-boxes,the rest should not have this option. so on..
how do i achieve this.Kindly help.

You'll need to use JavaScript...I have a complicated example and a simple example, however, I cannot really understand the complex example but I know how it works. The looping is too complex for me.
First you'll need to populate a server side variable...depending on how often the data is updated you may want this to run each time a new session is created...this example is run each time Tomcat is started and the application context is initialized:
package kms.web;
// Servlet imports
import javax.servlet.ServletContextListener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContext;
// utility imports
import java.util.Map;
// domain imports
import kms.domain.LocationService;
import kms.domain.DeptService;
import kms.domain.PatentService;
* This listenter is used to initialize
* the Maps of Locations, Patents & Depts used to populate
* pulldown lists in JSPs
public class InitializeData implements ServletContextListener {
    * This method creates the Maps.
   public void contextInitialized(ServletContextEvent sce) {
      ServletContext context = sce.getServletContext();
      LocationService lServ = new LocationService();
      // Create the Maps
      Map campuses = lServ.getCampuses();
      Map buildings = lServ.getBuildings();
      Map floors = lServ.getFloors();
      Map locs = lServ.getLocations();
      // And store them in the "context" (application) scope
      context.setAttribute("campuses", campuses);
      context.setAttribute("buildings", buildings);
      context.setAttribute("floors", floors);
      context.setAttribute("locs", locs);
      DeptService dServ = new DeptService();
      Map depts = dServ.getDepts();
      context.setAttribute("depts", depts);
      PatentService pServ = new PatentService();
      Map patents = pServ.getPatents();
      context.setAttribute("patents", patents);
      //I did this one myself
/*    CodeService cServ = new CodeService();
      Map masterMks = cServ.getCodes();
      context.setAttribute("masterMks", masterMks);
    * This method is necessary for interface.
   public void contextDestroyed(ServletContextEvent sce) {
   // I have no clue what the heck this is for???
   // Let me know if you do!
}So now we travel into the PatentService method called 'getPatents();' which in turn calls a PatentDAO method
Map patents = pServ.getPatents();
Below is the code for the PatentService object:
package kms.domain;
import kms.util.ObjectNotFoundException;
import java.util.*;
* This object performs a variety of dept services, like retrieving
* a dept object from the database, or creating a new dept object.
public class PatentService {
   * The internal Data Access Object used for database CRUD operations.
private PatentDAO patentDAO;
   * This constructor creates a Dept Service object.
public PatentService() {
    patentDAO = new PatentDAO();
public Map getPatents() {
      Map patents = null;
      try {
        patents = patentDAO.retrieveAll();
      // If the dept object does not exist, simply return null
      } catch (ObjectNotFoundException onfe) {
        patents = null;
      return patents;
}It may be useful for you to see the code of the Patent class:
package kms.domain;
/*** This domain object represents a dept.
public class Patent implements java.io.Serializable {
private int codeGgm;
private String name = "";
private String description = "";
private int creator;
private String creationDate = "";
private int used;
   * This is the full constructor.
public Patent(int codeGgm, String name, String desc, int creator, String creationDate, int used) {
    this.codeGgm = codeGgm;
    this.name = name;
    this.description = desc;
    this.creator = creator;
    this.creationDate = creationDate;
    this.used = used;
public Patent() { }
public int getCodeGgm() {
      return codeGgm;
public void setCodeGgm(int codeGgm) {
       this.codeGgm = codeGgm;
public String getName() {
    return name;
public void setName(String name) {
      this.name = name;
public String getDesc() {
    return description;
public void setDesc(String desc) {
      this.description = desc;
public int getCreator() {
      return creator;
public void setCreator(int creator) {
       this.creator = creator;
public String getCreationDate() {
      return creationDate;
public void setCreationDate(String creationDate) {
       this.creationDate = creationDate;
public int getUsed() {
       return used;
public void setUsed(int used){
       this.used = used;
}And here is the Database table which stores the Patents:
DESC PATENT:
CODE_GGM NUMBER(3)
NAME VARCHAR2(15)
DESCRIPTION VARCHAR2(250)
CREATOR NUMBER(10)
CREATION_DATE DATE
USED NUMBER(1)
So, we then travel into the code of the PatentDAO to see how the DAO object executes the DB query to get all of the Data we need for the select list:
package kms.domain;
import javax.naming.*;
import javax.sql.*;
import java.util.*;
import java.sql.*;
import kms.util.*;
* This Data Access Object performs database operations on Patent objects.
class PatentDAO {
   * This constructor creates a Patent DAO object.
   * Keep this package-private, so no other classes have access
PatentDAO() {
* This method returns a Map of all the Dept names
* The key is the Dept id
Map retrieveAll()
     throws ObjectNotFoundException {
      Connection connection = null;
      ResultSet results = null;
      // Create the query statement
      PreparedStatement query_stmt = null;
      try {
        // Get a database connection
      Context initContext = new InitialContext();
       DataSource ds = (DataSource)initContext.lookup("java:/comp/env/jdbc/keymanOracle");
       connection = ds.getConnection();
        // Create SQL SELECT statement
        query_stmt = connection.prepareStatement(RETRIEVE_ALL_NAMES);
        results = query_stmt.executeQuery();
        int num_of_rows = 0;
      Map patents = new TreeMap();
       // Iterator over the query results
        while ( results.next() ) {
            patents.put(new Integer(results.getInt("code_ggm")), results.getString("name"));
         if ( patents != null ) {
                return patents;
              } else {
                throw new ObjectNotFoundException("patent");
       // Handle any SQL errors
     } catch (SQLException se) {
        se.printStackTrace();
       throw new RuntimeException("A database error occured. " + se.getMessage());
    } catch (NamingException se) {
      throw new RuntimeException("A JNDI error occured. " + se.getMessage());
      // Clean up JDBC resources
      } finally {
        if ( results != null ) {
          try { results.close(); }
          catch (SQLException se) { se.printStackTrace(System.err); }
        if ( query_stmt != null ) {
          try { query_stmt.close(); }
          catch (SQLException se) { se.printStackTrace(System.err); }
        if ( connection != null ) {
          try { connection.close(); }
          catch (Exception e) { e.printStackTrace(System.err); }
private static final String RETRIEVE_ALL_NAMES
      = "SELECT code_ggm, name FROM patent ";
}Now when you wish to use the 'combo box' (also called select lists), you insert this code into your jsp:
<TR>
<%@ include file="../incl/patent.jsp" %>
</TR>
depending on how your files on your server are organized, the "../incl/patent.jsp"
tells the container to look up one directory from where the main jsp is to find the 'patent.jsp' file in the 'incl' directory.
I need some help creating multi-level select lists with JavaScript:
Can anyone explain this code:

This produces a related select list with 4 related lists by outputting JavaScript to the page being served. It works the same way as the first example that I describe but I don't understand the looping...maybe someone could explain how to go from the single select list to a double and/or triple level drill down?

OOABAP-How to access the protected methos from a class

How to access the protected methos from a class..There is a built in class..For tht class i have created a object..
Built in class name : CL_GUI_TEXTEDIT
method : LIMIT_TEXT.
How to access this..help me with code

hi,
If inheritance is used properly, it provides a significantly better structure, as common components only
need to be stored once centrally (in the superclass) and are then automatically available to subclasses.
Subclasses also profit immediately from changes (although the changes can also render them invalid!).
Inheritance provides very strong links between the superclass and the subclass. The subclass must
possess detailed knowledge of the implementation of the superclass, particularly for redefinition, but also in
order to use inherited components.
Even if, technically, the superclass does not know its subclasses, the
subclass often makes additional requirements of the superclass, for example, because a subclass needs
certain protected components or because implementation details in the superclass need to be changed in
the subclass in order to redefine methods.
The basic reason is that the developer of a (super)class cannot
normally predict all the requirements that subclasses will later need to make of the superclass.
Inheritance provides an extension of the visibility concept: there are protected components. The visibility of
these components lies between that of the public components (visible to all users, all subclasses, and the class itself), and private (visible only to the class itself). Protected components are visible to and can be used by all subclasses and the class itself.
Subclasses cannot access the private components particularly attributes) of the superclass. Private
components are genuinely private. This is particularly important if a (super)class needs to make local
enhancements to handle errors: it can use private components to do this without knowing or invalidating
subclasses.
Create your class inse24 and inherit this CL_GUI_TEXTEDIT
class in yours. You can then access the protected methods.

How to access the mysql using ordinary command line in Azure Website?

Hi
I deploying Django project on Azure. I created project and MySQL db according this method: https://pytools.codeplex.com/wikipage?title=PollsDjangoSql . I can create tables using django command "syncdb" in Visual Studio. I see
db structure in SQL Explorer. All works. But now I need to get access directly to mysql. For example with a view to set encoding of some column, or set permissions, change user password, etc.
I found about many different tools and methods in Microsoft portal. But the purpose of these tools, how to install it and how to use it is a very entangled (After several attempts to find out what's what two weeks later I found on my computer
three dozen programs with unknown purpose. I doubt that I need to install so many tools to just add the user in mysql).
How to access the mysql using ordinary command line (or the same simple tool) in my case?

Hi pvgdrk,
To get access directly to a mysql database, you can use the commandline tool(open a cmd window-->type mysql the commadline ) or the
GUI MySQL workbench.
Since this is a question about MySQL, I would suggest you post your question in a dedicated MySQL forum. You will get more prompt response.

How to copy the structure of a Field Symbol?

Hi,
          I have a requirement where in a dynamic Internal table is supposed to be created. I have created that dynamic table using the class method cl_alv_table_create=>create_dynamic_table. Here I have a structure in the field symbol. My requirement is how do I create a internal table with the structure that is there in the field symbol?...
and i'm unable to refer to the field that is dynamically created in the field symbol.
Like,
<gfs_tab>-pernr = itab-pernr.
in the above stmt the field pernr is created in the field symbol dynamically.
Thanks,
Deepak.

Hi Matt,
            my objective is to create an internal table with structure that i have obtained in <gfs_tab> .
other than the pernr, there are many fields dynamically generated.
say if I have generated the following structure in <gfs_tab> :
pernr            ename1            day1             day2                 day3
then I want to create an internal table with the above structure so that my internal table will have fields:
1) pernr
2) ename1
3) day1
4) day2
5) day3
for each execution of the report there will be different structure generated in <gfs_tab> depending upon the inputs that I give.
Thanks,
Deepak.

I need to know how to access the book pod in robohelp 8/

i need to know how to access the book pod in robohelp 8/

Hi there
Actually, by my count there are at least five ways to coax books into the TOC
From the menu, Click File > New > Book.
Type the keyboard shortcut of Ctrl+Shift+B.
Right-click the pod and choose New > Book.
Click the New Book icon in the pod toolbar.
If you have organized your project using folders, you may automatically create a TOC based on the file structure and each folder becomes a book. There are also multiple ways to automatically create the TOC. One is by right-clicking the TOC pod. Another is by clicking an icon in the pod toolbar and another is by clicking the Tools menu.
Cheers... Rick

How to access the photos on icloud

hi
how to access the photos which i saved in i cloud, from my iPhone 5,
Note: i do not use any PC. and i only have purchased 20 GB of space on an annual sub. so as to save my photos, and create space in my phone and now i am unable to access it,
please advise

There isn't really a way to "save" photos to iCloud currently with non-beta software.
iCloud is involved with photos in 2 ways -- backup and Photo Stream.
Backup of an iOS device includes Camera Roll photos but they cannot be viewed at iCloud.com -- the backup can only be used when doing a restore of an iOS device.
Photo Stream photos also cannot be viewed at iCloud.com; Photo Stream is designed as a method of transferring photos from one device to another and is not designed to store the photos. More info http://support.apple.com/kb/HT4486
There is a new feature -- "iCloud Photo Library" -- coming sometime after the iOS 8 release next week: http://www.macrumors.com/2014/09/12/apple-demotes-icloud-photo-library-beta/

I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

HDD is a Toshiba 1TB, partitioned into two 500GB partitions.

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.

Have you tried to repair the disk yet
