Populate block with an sorted array contents.
hey,
i'm trying to populate a block (forms 10 vs. db 10g) with data from an array.
the data should be sorted.
what is the easiest way to do it?
another deatails (array structure)) will supplied if nessecary.
thanks , yair
How do you populate your array? If you populate it with a query in some way the easiest way would be not to use an array at all and simply populate the block with your query. This would spare you manually populating the block and implementing a sort algorithm yourself (just use order by)
If the data comes from what ever else source a pipelined function comes to my mind which would enable you to query your array with SQL and letting the SQL Engine do the sort. You'd just have to use a from-clause query on your block

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"

</HeaderedContentControl>

</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>
''' Common functionality for ViewModels of an individual ContactDetail

Public MustInherit Class vmParty
Inherits ViewModelBase
''' <summary>
''' Gets the underlying ContactDetail this ViewModel is based on
''' </summary>
Public MustOverride ReadOnly Property Model() As tblParty
'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on
'''' </summary>
'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.

Block with more than one table type agurment - Update Procedure for Block
Hi,
I have one form with 3 Block. First Block is single row block, and other 2 are details block . The details balocks are based on the Procedure datasource, because of the complex query conditions. Now my requirement is When Inserting / Updating the Master Block (Single Row Block), I need to get the values in the two details block , because I need to update some other tables also based on these values. I created a procedure with two Table Type parameters (for each details block) , but when I using this procedure as the Update Procedure Name in the block, I am getting the error Only One table type arguement is allowed. Is there any other method to implement this.
Thanks in advance.Rizly,
A quick summary to make sure I understand your requirements. You have a single row base table master block with two detail blocks that are based on Procedures. When you update the single row base table master block, you need all of the data in the two procedure based detail blocks as there are updates that you have to perform to other tables that use this data. You have created a stored procedure that take two PL/SQL tables as parameters, but you are getting the error that only 1 table parameter is allowed.
I need to ask you a few questions first. What is your Forms version? The stored procedure you created; are you using this procedure in the "On-Insert, On-Update, On-Delete" triggers or do you call the procedure in one of the Base Table block ("Key-Commit, When-Button-Pressed" or other trigger)? When you modify or add a new Master block record are you adding values to the detail blocks or using values from the previous Master block record?
If you are using your procedure in the On-Insert, On-Update or On-Delete trigger(s), then based on your description, the error you are receiving is correct. The "On-..." triggers are constrained in that their procedures expect only a single PL/SQL table, Table of Records or Ref Cursor as a parameter. This is a Forms constraint - not a PL/SQL constraint as Forms is expecting you to only perform actions on the block where the "On-..." Trigger is located.
Perhaps you should consider creating a database Package that has two package specification constructs (Ref Cursor, Table of Records, etc) you can populate from Forms and then simply call the package procedure that will use the Ref Cursors to perform the needed update or inserts.
Hope this helps.

Help with comparing string array with parameters
I've posted my code in full so hopefully everyone can see exactly what I have been doing.
Note - my code uses the observer/observable model. The method I am having the problem with the if statement is in the class HSBC.
Basically when the pin count reaches 4 (in the atm class) it sends the userid & pincode) over to the checkPinAndUserId(String pinCode, String userCode) method. Here the if statement should check the userid to see if the string parameter matches a string in the array. If it does it should check in the same position in the pin array to check the pin no is correct and then return true.

I'm new to java and have been told that using the observer/observable model is not considered basic java. So that is the only reason I posted it in this section. At the same time i feel that the bit I'm struggling with is actually basic - hence posting it in the basic section. I'm not sure if people of all abilities check all forums or just the ones they feel at at their standard.
So appologies if you've taken offence. -
Search issue with dynamic dropdown array - PHP
I'm currently trying to set up a search with a couple of
dynamic dropdowns, basically to search for cars - so the parent
list is car make, and the child is car model.
I've gotten as far as a page with the dynamic array working,
but not the search :
dynamic array
working
(Ignore the cars and vans radio buttons)
For testing there's an Audi A3 and and Audi A6, but this
search doesn't work.
The select code looks like :
<select name="Model">
<option value="" <?php if (!(strcmp("",
$row_rsModels['Model']))) {echo "selected=\"selected\"";}
?>>Select a Model</option>
</select>
And the array code looks like :
<?php
if ($row_rsModels) {
echo "<SC" . "RIPT>\n";
echo "var WAJA = new Array();\n";
$oldmainid = 0;
$newmainid = $row_rsModels["Make"];
if ($oldmainid == $newmainid) {
$oldmainid = "";
$n = 0;
while ($row_rsModels) {
if ($oldmainid != $newmainid) {
echo "WAJA[".$n."] = new Array();\n";
echo "WAJA[".$n."][0] = '".WA_DD_Replace($newmainid)."';\n";
$m = 1;
echo "WAJA[".$n."][".$m."] = new Array();\n";
echo "WAJA[".$n."][".$m."][0] =
"."'".WA_DD_Replace($row_rsModels["ModelID"])."'".";\n";
echo "WAJA[".$n."][".$m."][1] =
"."'".WA_DD_Replace($row_rsModels["Model"])."'".";\n";
$m++;
if ($oldmainid == 0) {
$oldmainid = $newmainid;
$oldmainid = $newmainid;
$row_rsModels = mysql_fetch_assoc($rsModels);
if ($row_rsModels) {
$newmainid = $row_rsModels["Make"];
if ($oldmainid != $newmainid) {
$n++;
echo "var rsModels_WAJA = WAJA;\n";
echo "WAJA = null;\n";
echo "</SC" . "RIPT>\n";
function WA_DD_Replace($startStr) {
$startStr = str_replace("'", "|WA|", $startStr);
$startStr = str_replace("\\", "\\\\", $startStr);
$startStr = preg_replace("/[\r\n]{1,}/", " ", $startStr);
return $startStr;
?>
..to try and find the root of the problem, I've gotten as far
as a similar page, without the dynamic
array, with the child dropdown populated dynaically from the
recordset :
search working
This seems to work exactly as advertised - all the car models
are listed from the recordset, and if
you search for Audi and A3, then it gets returned correctly.
The select code here looks like :
<select name="Model" id="Model">
<option value="">Select a Model</option>
<?php
do {
?>
<option value="<?php echo
$row_rsModels['Model']?>"><?php echo
$row_rsModels['Model']?
></option>
<?php
} while ($row_rsModels = mysql_fetch_assoc($rsModels));
$rows = mysql_num_rows($rsModels);
if($rows > 0) {
mysql_data_seek($rsModels, 0);
$row_rsModels = mysql_fetch_assoc($rsModels);
?>
</select>
..so I guess the search is set up OK, but the issue is with
how to pass the model from the select code generated by the dynamic
array correctly....
Its presumably because the option value is empty :
<option value="" <?php if (!(strcmp("",
$row_rsModels['Model']))) {echo "selected=\"selected\"";}
?>>Select a Model</option>
So I've been trying various possibilities with no joy, such
as :
<?php if (!(strcmp("", $row_rsModels['Model']))) {echo
"selected=\"selected\"";} ?>
but without success.
Even then, I'd have though if the value was empty, "", then
it would return all results, rather than no results....?
hope that makes some sense, and someone can shed some
light...

But how come the class documentation says its possible.
Functionality
Using class CL_SALV_WD_UIE_DROPDOWN_BY_IDX, you make all the settings for the UI element index-based dropdown list box, from which the user can select from a range of values.
*You use the index-based dropdown list box if the dropdown list boxes in each cell of the column are to contain different entries.*
You use the key-based dropdown list box if the dropdown list boxes in each cell of the column are to contain the same entries.
To specify the entries in the dropdown list boxes, the context of your application requires an attribute for which the data type satisfies the following requirements:
The attribute is a table
The structure of this table contains at least one KEY column and a VALUE column.
Note
We recommend that you use the type WDY_KEY_VALUE_TABLE here. -

TreeSet vs Collection.Sort / Array.sort for Strings
Gurus
I am pondering weather to use TreeSet vs the Collections.sort / Array.sort for sorting Strings.
Basically I have a list of Strings, i need to perform the following operations on these Strings
1) Able to list Strings starting with a Prefix
2) Able to list Strings Lexically greater than a String
Any help would be greatly appreciated!
Thanks a bunchSpaceShuttle wrote:

Thanks a bunchBig-O wise, there's no difference between sorting a list of N elements or inserting them one by one in a tree-set. Both take O(n*log(n)). But both collections are not well suited for looking up string that start with a certain substring. In that case you had better use a Patricia tree (or Radix tree).
Good luck. -

Hi,
I have an array List which have values like empid, amount, corpcode eg.
223, 345.95, SDB
791, 567.75, XYZ
115, 345.95, SDB
I need to sort this array like this
115, 345.95, SDB
223, 345.95, SDB
791, 567.75, XYZ
How can I do this?
ThanksYou have to implement a natural order for your object, so that it can be sorted. There are a lot of tutorials out there for this, but I will do it anyway for you:
public YourClass implements Comparable<YourClass>{
int firstNumber;
int secondNumber;
int thirdNumber;
String someIdentifier;
public int compareTo(YourClass otherObject){
int difference = this.firstNumber - otherObject.firstNumber;
if(difference != 0) return difference;
difference = this.secondNumber - otherObject.secondNumber;
if(difference != 0) return difference;
return this.someIdentifier.compareTo(otherObject.someIdentifier);
}As you can see, the basic idea is, that you return if an object is greater, equal or less than another. You begin with the most important criteria. If this one is equal, you check the next one.
Some objects already include the comparable interface, like String. If this is the case, you can take advantage of this, and use their compareTo Method.
After this, you can sort your objects with
Collections.sort(someList); -
Combining boost and bury with dgidx sort parameters
I have setup productprice as dgidx sort parameter so as to show the product listing from lowest to highest. But, when I try to boost some record to the top, the record shows up at the first but the order thereafter is random. I want the boosted records to show first followed the other records in sorted order. I tried the same thing with burying the records and the sorting order is lost. Is there a way to boost and bury records and still continue to keep the dgidx sort index for the records displayed between the boost and buried records?
Thank you.I used relevance ranking with static module and sort on the same field with in the template. This enabled the sort parameter and relevance ranking parameter to flow through from the workbench along with the boost and bury data. Finally, I got to the combined list which had boosted and buried data along with the sorted data in the middle.

Sun C++ std::sort coredump during sorting array of long values
Hello,
I got core dump during execution following test program on both Solaris 9 (compile by CC: Sun C++ 5.5 Patch 113817-19 2006/10/13) and Solaris 10 platforms (compile by CC: Sun C++ 5.9 SunOS_sparc Patch 124863-01 2007/07/25).
Core is dumped during sorting array of about 120k elements of unsigned long types using STL std:sort. The input data is available at link: [file.txt|http://www.savefile.com/files/1924004]
When I change sorting methods to std::stable_sort program works fine.
The funny thing is that when I change order of last two values of input data (swap), sorting is successful with std::sort.
Can anyone tell me if it is Sun C++ compiler bug ?Can I use std::stable_sort method safely?
Below code:
#include <iostream.h>
#include <fstream.h>
#include <set>
#include <string>
int main( int argc, char** argv )
char readStr[256];
ifstream file;
unsigned long *l;
int i=0;
l = new unsigned long[119016];
if (l ==0)
cout << "Error in allocate memory";
return -1;
file.open("file.txt");
if (!file)
cout << "Error in openening file";
return -1;
while(file.getline(readStr, 256,'\n'))
cout << readStr<<endl;
l= atol(readStr);
cout << l[i]<<endl;
i++;
std::sort(l,l+119016); //core dump here!!!
for (i=0;i<119016;i++)
cout <<l[i]<<endl;
file.close();
delete [] l;
return( 0 );
Greetings
RobertYou have run into bug 6588033 "std::sort from libCstd loops", which is fixed in current patches.
Get the current patches for Sun Studio and also the current patch for the C++ runtime libraries (SUNWlibC patch).
You can find them here:
[http://developers.sun.com/sunstudio/downloads/patches/index.jsp]
Sun C++ 5.5 probably does not have the fix, since it is quite old and falling out of support.
C++ 5.9 does have the fix. -
Help with a Vector Array - pppppplllllllleeeeaaasse!!!!!!!
Hi I'm having a mare with a Vector Array that I want to contain String variables. I know you get a warning with the traditional implementation of a vector, and I have over come that using:
private Vector <String> MyVector = new Vector<String>();
But I also need to create a Vector Array and I am getting some very strange results - for a start in JPadPro it only comiles every second attempt, with every other failing due to the implementation of the Vector array.
Below is a snippet of the code that I have sort of got to compile but with a compiler warning:
private Vector<String>[] MyVector; //this is line 75
int Array;
public myClass()
Array = 5;
MyVector = new Vector[ Array ];
for( int i = 0; i < Array; i++ )
MyVector[ i ] = new Vector<String>();
The first time I complie I get:
CreateMessage.java Line 75: Syntax Error
The Second time I compile I get:
CreateMessage.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
Finished
I hate complier errors - I have gotten quite a few but have managed to remove them all but this one by searching the forum. Any help on the correct implementation of my Vector Array would be great,
Thanks in advance,
