How to extend VO which is use in VIEW LINK and VL is created dynamically.

Hi All,
I wants to extend VO.
This VO is used in VIEW LINK.
This VL name set dynamically, conditionally in one of the controller of page.
i.e if some condition satisfied than xyz VL will use otherwise abc VL will use.
Now,
I have extend VO as well as VL and substitute both, but I am getting null value for some of the field and also I am not able to insert/update new value.
So,
I have created VORowImpl class file which extend VOROWImpl of seeded file and chage the row class of VO.xml file to new class. i.e. modified seeded .xml code and achieve what I want.
But Is this correct way ?
Is there any other way ?

Hi pratap,
thanx for your reply.
intially i've done that also. i.e. extend only VO and substitute it but i'm getting null values in some field as well as nt able to insert/update new value.
the error is related to VL.

You can install Perian,
http://www.perian.org/
although this will be the last version, and Flip4Mac.
http://download.cnet.com/Flip4Mac-WMV-Player/3000-13632_4-87679.html
Otherwise you may have to look at a different and more extensive player such as VLC

ADF: use of view link Accessor in Entity Object = always null?

Hi,
JClient 9.0.5.2, adf model.
I would like to use the view link accessor method in the master EO to retrieve detail EO values and the view link accessor method in the detail EO to retrieve master EO values.
Detail Rule:
In the detail EO an attribute is derived from an attribute of the master EO: detail attribute = master attribute.
Master Rule:
In the master EO an attribute is derived from the detail EO: master atribute set to 0 if detail EO exist else set to 0.
Tables:
Table Master => MasterEO => MasterVO
- masterPK (not updateable)
- masterField (not updateable)
- hasDetailsFlag
Table Detail => DetailEO => DetailVO
- detailPK (not updateable)
- masterPK => foreign key (not updateable)
- masterField (query only)
MasterDetailLink based on foreign key.
In link wizard I asked for the generation of following accessors in the source & destination Entity Objects:
In DetailEO accessor name: RetrieveFromMaster
In MasterEO accessor name: RetrieveFromDetail
In the DetailEO, I asked for the generation of the DetailEOImpl file, accessors and create method.
As wriiten in the file, before the create method:
** Add attribute defaulting logic in this method. **
I tought this is the place to retrieve the master attribute:
The code:
MasterVORowImpl masterVO = getRetrieveFromMaster();
if (masterVO == null)
System.out.println("MasterVORowImpl masterVO create NNNNNNNNNNNUUUUUUUULLLLLLLLLL");
The masterVO is always null?
I suppose I didn't understand something, my guest is that ViewObjects may not be used for default logic?
I know how to implement those rules in the database with triggers.
I think that the data I need for implementing those rules exist somewhere at the ADF level so retrieving the data from the db is not necessary?
Could somebody give some clues?
I didn't find a similar example in the Business Rules in BC4J document.
Your help will be appreciated
Frederic

Hi,
Detail Rule, copy attribute value form master.
In DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
super.create(attributeList);
Master rule, set flag to 0 if no details else set to 1.
In the MasterEOImpl added method to check if detail row exists based on Row Iterator => no db retrieval?
This method also sets the flag accordingly:
protected void checkHasOtherDetails()
oracle.jbo.RowIterator ri = this.getRetrieveFromdetail();
ri.last();
// last() must be called else hasNext() returns true even on last delete ???
Number hasDetails = Constants.NUMBER_NO; // = 1
if (ri.hasNext() || ri.hasPrevious())
hasDetails = Constants.NUMBER_YES; // = 0
if (!getHasDetailsFlag().equals(hasDetails)) {
this.setHasDetailsFlag(hasDetails);
I call this method in the remove method of the detailEOImpl:
public void remove()
this.getRetrieeFromMaster().checkHasOtherDetails();
super.remove();
To set the flag I added follwoing code in the create method of the DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
**** ADDED ***
Number masterHasDetailsFlag = getRetrieveFromMaster().getHasDetailsFlag();
if (!masterHasDetailsFlag.equals(Constants.NUMBER_YES)) {
getRetrieveFromMaster().setHasDetailsFlag(Constants.NUMBER_YES));
super.create(attributeList);
One more question:
Is there a danger of calling last() on row iterators in create/update/remove methods of *Impl files?
=> current row changed => any effect on display in JPanel
Thanks

How to find which authentication used to site collection and site using powershell

Hi,
How to find how-many web app, sitecollection, site used Windows authentication,claim authentication and classic, secure store authention , adfs authentication using powershell code in sharepoint 2013.
If sites are used adfs authentication how to find which email id used for that.
Thanks,

Authentication is only defined at the Web Application level, and the only valid auth methods are Classic (Windows (Basic/NTLM/Kerberos)), Claims (Windows (Basic/NTLM/Kerberos)), FBA Claims, , SAML Claims (ADFS), and Anonymous.
You can find out what authentication scheme(s) are enabled via:
$wa = Get-SPWebApplication http://webApp1$wa.IisSettings["Default"] #replace with the zone name you're interested in
The output will look similar to this:
PS C:\Users\trevor> $wa.IisSettings["Default"]
AuthenticationMode : Forms
MembershipProvider : i
RoleManager : c
AllowAnonymous : False
EnableClientIntegration : True
ServerBindings : {Microsoft.SharePoint.Admini
stration.SPServerBinding}
SecureBindings : {}
UseWindowsIntegratedAuthentication : True
UseBasicAuthentication : False
DisableKerberos : True
ServerComment : SharePoint
Path : C:\inetpub\wwwroot\wss\Virtu
alDirectories\spwebapp180
PreferredInstanceId : 42768054
UseClaimsAuthentication : True
ClaimsAuthenticationRedirectionUrl :
UseFormsClaimsAuthenticationProvider : False
FormsClaimsAuthenticationProvider :
UseTrustedClaimsAuthenticationProvider : False
UseWindowsClaimsAuthenticationProvider : True
OnlyUseWindowsClaimsAuthenticationProvider : True
WindowsClaimsAuthenticationProvider : Microsoft.SharePoint.Adminis
tration.SPWindowsAuthenticat
ionProvider
ClaimsAuthenticationProviders : {Windows Authentication}
ClaimsProviders : {}
ClientObjectModelRequiresUseRemoteAPIsPermission : True
UpgradedPersistedProperties : {}
So on this Web Application in the Default Zone you can tell I have Windows Claims enabled, not using Kerberos (so using NTLM), and Trusted (SAML/ADFS) is not enabled, neither is Forms or Anonymous.

How to find reports which are using sales tables

Hi Guys,
we are using OBIEE 10g version.Here i need to identify the the reports which are using sales tables.
Table names are given but how to find which report is using these tables.Is there any method to find
or we have to check all reports manually?
Could any one pls suggest me here!
Regards,
sk
Edited by: 912736 on Jun 8, 2012 1:24 PM

Hi SK,
You can run a report from catalog manager that willl give you all answers requests and the subject area columns in use, you can map these back to the sales tables either manually or by linking (vlookup) to an RPD report that you can run from the Admin tool.
The Usage Tracking method is pretty good but you will have to match up the reports using the Logical SQL.
I'd do both methods and cross ref your results to ensure nothing slips the net.

How to find out which application uses how many Web containers?

Hi everybody,
we are monitoring several JAVA engines via sapccmsr and often get a threshold overflow for SID\Server\...\Web Container\AllRequestsCount
The SAP online documentation tells me how to set a threshold for any web application. But befor that I should know, which application uses up all the Web Containers. How can I find out?
btw: Does the Threshold (1.000.000) make any sense, or is this just a number that may be changed without the fear for any consequences? Is there a serious performance impact?
Thank you in advance
Ralf

Ralf,
I have an opinion, that you can take a trace messages from Web Container service, which might give you some more details.
I am not completely sure if that serves your purpose. Still you can have a look in the below document, if it looks helpful.

How can I set which projects use Proxy Media and not just change every project?

Hi there
I can see how to change ALL projects to use Proxy Media or Original/Optimised Media
in
Preferences>Playback
But I'm switching between projects a lot and I only want to use Proxy Media on one project, so how can I tell FCPX to only use Proxy Media on that ONE project?
Thanks

Perhaps if apple didn't take back prores LT this wouldn't be as much of an issue.
Pores LT was a great compromise between file size and quality. It produced a fine image for most peoples needs and was 30% smaller.
Hopefully it will be returned soon. I can't imagine why it's not already there. Unless they want to charge for it, ... again..
Have you tried capturing as full res, then change prefs back to proxy, open a new project and import the full res files?
In FCP7 the render pref was separate from the capture pref. is that gone too?
If my idea doesn't work, Surely someone will chime in with a creative work around to this.
And hopefully it'll get fixed soon in an update.
Best,

When I delete duplicates how do I know which version is the original song and which is the duplicate?

I have recently transfered all my music to a new computer and duplicates have appeared in my itunes. I have chosen to 'show exact duplicates' so that it is easier for me to delete, but I can't work out which version of the song I need to delete. (When I click to delete on the top version a box appears stating 'move to recycle bin', but when I click on the second version the box which appears just says 'delete file from itunes.')
Also - does any one know where these duplicates have emerged from?!?
I hope I have given enough info. I would be super grateful if someone could shed some light on this!
Thanks.

Apple's official advice on duplicates is here... HT2905: How to find and remove duplicate items in your iTunes library. It is a manual process and the article fails to explain some of the potential pitfalls such as lost ratings and playlist membership.
Use Shift > View > Show Exact Duplicate Items to display duplicates as this is normally a more useful selection. You need to manually select all but one of each group to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks, however this works best when performed immediately after the dupes have been created. If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin.
Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background, this post for detailed instructions, and please take note of the warning to backup your library before deduping.
(If you don't see the menu bar press ALT to show it temporarily or CTRL+B to keep it displayed.)
The most recent version of the script can tidy dead links as long as there is at least one live duplicate to merge stats and playlist membership to and should cope sensibly when the same file has been added via multiple paths.

How to edit a datagridview/textboxes using tableadapters in c# and sql

I am wondering what is the best way to edit a database that has multiple tables.
(Section 1) I have a Administration, Teacher and Student table that is linked up with the Person table which has a Primary Key.
The Person table consists of the general information of the person.
The Student table consists of information about the student; student ID and qualification code.
The Teacher table consists of information about the teacher; teacher ID, Reg No and password.
The Administration table consists of information about the admin; admin ID, Role and password.
As the Primary Key in the Person table is the ID, I have linked up with each of the other's table with their appropriate ID.
(Section 2) I have a Course and Qualification table that is linked up with the Student and Teacher table as well as each other.
The course table constists of the Course ID, Course Name ... and Teacher ID.
The Qualifications table consists of Qualification Code, Qualification Name and Duration.
There is a section where I have to create a view which shows just the Student ID, Course ID and has the Student's Marks in it.
I have got a combobox which then links up with the dgv(datagridview).
I have got insert and delete methods for both sections. Here is an example of the insert method into the Admin/Person table.
try
personTableAdapter.Insert(aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text);
administrationTableAdapter.Insert(Convert.ToInt32(aAID1.Text), aRole.Text, aPassword.Text);
MessageBox.Show(aFirstName.Text + " " + aSurname.Text + " has been added. Your ID is " + aAID1.Text);
this.personTableAdapter.Fill(this._30002195DataSet.Person);
this.administrationTableAdapter.Fill(this._30002195DataSet.Administration);
catch (Exception ex)
MessageBox.Show(ex.Message);
Here is an example of the delete method in the Admin/Person table.
try
personTableAdapter.Delete(Convert.ToInt32(aID.Text), aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text);
administrationTableAdapter.Delete(Convert.ToInt32(aAID.Text), aRole.Text, aPassword.Text);
MessageBox.Show("Person Deleted");
this.personTableAdapter.Fill(this._30002195DataSet.Person);
this.administrationTableAdapter.Fill(this._30002195DataSet.Administration);
catch (Exception)
MessageBox.Show("Cannot delete Person");
Those methods above are working fine, what I'm having problems with, is with the editing/updating part.
I have tried a few things and haven't worked.
Here's an example of an edit, while trying to use textboxes.
personTableAdapter.Update(aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text, Convert.ToInt32(aID.Text), aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text);
administrationTableAdapter.Update(aRole.Text, aPassword.Text, Convert.ToInt32(aAID.Text), aRole.Text, aPassword.Text);
personBindingSource.EndEdit();
administrationBindingSource.EndEdit();
administrationTableAdapter.Update(_30002195DataSet.Administration);
personTableAdapter.Update(_30002195DataSet.Person);
MessageBox.Show("Person Updated");
this.personTableAdapter.Fill(this._30002195DataSet.Person);
this.administrationTableAdapter.Fill(this._30002195DataSet.Administration);
Here I tried to do the new values/original values, while trying to use textboxes
personTableAdapter.Update(aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text, Convert.ToInt32(aID.Text), aFirstName.Text, aSurname.Text, Convert.ToDateTime(aDoB.Text), aPhone.Text, aAdd1.Text, aAdd2.Text, aSuburb.Text, aState.Text, aPostcode.Text, AdminType.Text);
administrationTableAdapter.Update(aRole.Text, aPassword.Text, Convert.ToInt32(aAID.Text), aRole.Text, aPassword.Text);
Trying to use the example through the mdsn, this is trying to use the datagridview.
this.Validate();
personBindingSource.EndEdit();
teacherBindingSource.EndEdit();
_30002195DataSet.PersonDataTable deletedPerson = (_30002195DataSet.PersonDataTable)
_30002195DataSet.Person.GetChanges(DataRowState.Deleted);
_30002195DataSet.PersonDataTable newPerson = (_30002195DataSet.PersonDataTable)
_30002195DataSet.Person.GetChanges(DataRowState.Added);
_30002195DataSet.PersonDataTable modifiedPerson = (_30002195DataSet.PersonDataTable)
_30002195DataSet.Person.GetChanges(DataRowState.Modified);
try
if (deletedPerson != null)
personTableAdapter.Update(deletedPerson);
teacherTableAdapter.Update(_30002195DataSet.Teacher);
if (newPerson != null)
personTableAdapter.Update(newPerson);
if (modifiedPerson != null)
personTableAdapter.Update(modifiedPerson);
_30002195DataSet.AcceptChanges();
catch (System.Exception ex)
MessageBox.Show(ex.Message);
finally
if (deletedPerson != null)
deletedPerson.Dispose();
if (newPerson != null)
newPerson.Dispose();
if (modifiedPerson != null)
modifiedPerson.Dispose();
MessageBox.Show("Updated");
this.personTableAdapter.Fill(this._30002195DataSet.Person);
this.teacherTableAdapter.Fill(this._30002195DataSet.Teacher);
Now because I am trying to edit a certain user which requires the Person table along with the other table, it just doesn't seem to work at all.
With the datagridview, I made a new view in the sql and it has both tables combined and shows when I bring it out from the datasource, but where I go into the dataset builder and try to create an update method, all I get is the "Update" not what
I would get when I created the update method from just the person's table by itself.
Can someone provide me with an example or help me out someway because I am struggling with this, I can't seem to find much information at all.
Thanks.

I have used the designer to create a new datagridview, when using that dgv it doesn't want to update to the relevent tables in my database. So say you have the person and admin dgv together and you need to update it, how would you get it to work
to the database? I did just end up using 2 seperate dgv's but it won't get accepted.
try
_30002195DataSetTableAdapters.PersonTableAdapter personTableAdapter = new _30002195DataSetTableAdapters.PersonTableAdapter();
// person table
_30002195DataSetTableAdapters.AdministrationTableAdapter administrationTableAdapter = new _30002195DataSetTableAdapters.AdministrationTableAdapter();
// admin table
ViewSetTableAdapters.AdminViewTableAdapter adminviewTableAdapter = new ViewSetTableAdapters.AdminViewTableAdapter();
// tried using this for both the admin/person tables together but didn't work?
this.Validate();
adminViewBindingSource.EndEdit(); //both
personBindingSource.EndEdit();
administrationBindingSource.EndEdit();
personTableAdapter.Update(_30002195DataSet.Person);
administrationTableAdapter.Update(_30002195DataSet.Administration);
MessageBox.Show("Updated");
this.personTableAdapter.Fill(this._30002195DataSet.Person);
this.administrationTableAdapter.Fill(this._30002195DataSet.Administration);
catch (Exception ex)
MessageBox.Show(ex.Message);
So, how would I write the code so it edits both the tables from just the one dgv?
Hello,
Based on these words above, it seems that the key issue is that you want to display and edit the data of two tables with a single datagridview, right? If so, I am afraid that I would recommend you consider using code other than designer to get that done.
Are these table store in the same database?
If so, then you could consider getting that done with ADO.NET, we could getting the data of multiple table with sql query. You could consider
using sql query to get all data from multiple tables
of database, and then fill them to a single datatable.
For query issue, you could consider getting help from
Transact-SQL forum.
If not, then we need to create update query for both table and execute these queries with sperate connection strings.

Carl

How to make system update with "use automatic configuration script" and an URL

I mean there is no general method which is capable of correcting all possible errors found by schema validation.
For example if the validation says it expected to find an <organization> element or a <company> element but it found a <banana> element, there is no way to determine what repair is necessary.
Anyway the requirement is fighting against the way things work in the real world. The purpose of validation is just to find out whether a document matches a schema. If it doesn't, then too bad. Send it back to be fixed or replaced. If you are having a problem because you repeatedly get documents which don't quite match your schema, then you need to train the users to produce valid documents or to give them tools which help them do that.
