Iterating through a GroupItem selection (actionscript)

Driving me crazy. Converting some Javascript to Actionscript for an extension. Have a selection. Need to iterate through selection, and then when finding groups, iterate through groups to get geometricbounds.
in Javascript GroupItem.Pageitems[i] will allow me to access properties of items in the group. Actionscript is a big fat 1009 NULL error. Probably some type error since GroupItem is Object?
This simple code throws the error. I have two rectangles grouped. That is what is selected.
var mySelItem:Array = app.activeDocument.selection as Array;
                     if (mySelItem[0] is GroupItem){
                          var myPath:PathItem = mySelItem[0].PageItems[0]
                     myPath.remove()
Can somebody give me the line of code that will allow me to access children of GroupItem and get properties?

OK,
Of course shortly after I post the answer is there.
This:
var mySelItem:Array = app.activeDocument.selection as Array;
                     if (mySelItem[0] is GroupItem){
                          var myPath = mySelItem[0].PageItems.index(0)
                     myPath.remove()
Knew it was easy... just not obvious.

SharePoint Online Iterating through Document Libraries CSOM

Hi,
I am trying to iterate though a document library and set each document/items whithin to inherit permissions (at the moment each doc/item is using uniquer permissions).
I am able to get the specific document library that I am interesting in, however I cannot at the moment iterate though each of the items/documents within it, but here is what I have so far:
Add-Type -Path "Libraries\Microsoft.SharePoint.Client.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.Linq.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.dll"
$webUrl = "https://test.sharepoint.com/sites/testsite"
$username = "####"
$password = "####"
$securePass = ConvertTo-SecureString $password -AsPlainText -Force
$listname = "TestDoc";
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($webUrl)
$ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $securePass)
#variables
$web = $ctx.Web
$lists = $web.Lists
$ctx.Load($lists)
$ctx.Load($web)
$ctx.ExecuteQuery()
#print web URL
write-host `n "Web Url:" `n $web.Url
foreach ($list in $lists)
if ($list.Title -eq "TestDoc")
#print list name if found
write-host `n "Found the list:" `n $list.Title `n
#attempting to iterate through items in the document library
foreach ($item2 in $list.Items)
#list the items/documents in the document library
write-host $item2.Title
It is the foreach loop I am having trouble at the moment as I am not sure how to loop though each of the items/documents in the document library.
Any suggestions on the approach I should take would be much appreciated.

Thanks for the heads up, I have re-worked my script which is simpler and now works like a charm:
Add-Type -Path "Libraries\Microsoft.SharePoint.Client.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.Linq.dll"
Add-Type -Path "Libraries\Microsoft.SharePoint.dll"
$webUrl = "https://test.sharepoint.com/sites/testsite"
$username = "####"
$password = "####"
$securePass = ConvertTo-SecureString $password -AsPlainText -Force
$listname = "TestDoc"
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($webUrl)
$ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $securePass)
#get the List/DocLib and load it for use
$listUpdate = $ctx.Web.Lists.GetByTitle($listname)
$ctx.Load($listUpdate)
$ctx.ExecuteQuery()
#CAML Query to get all items inclusing sub-folders
$spQuery = New-Object Microsoft.SharePoint.Client.CamlQuery
$spQuery.ViewXml = "<View Scope='RecursiveAll' />";
$itemki = $listUpdate.GetItems($spQuery)
$ctx.Load($itemki)
$ctx.ExecuteQuery()
#iterating through the items and reseting permission inheritence
for($j=0; $j -lt $itemki.Count; $j++)

Avoid iterating through everything

Hello all,
Hope you guys can help me with this problem. I have a program that draws anywhere from 1-300,000 letters on a canvas. Each letter is created from a class called StringState which extends Rectangle. What I would like to do is have each letter respond when the user moves the mouse over the letter by growing bigger. I figured I can just see if the letters bounds contains the point where the mouse moved to and if it does change the letters size and repaint around that letter to update the display. This works great from 1-5000 letters but getting up to 10,000 or even higher creates a very visible lag while the program is iterating through the letters to check if the mouse location intersects the letters bounds. What I was wondering is there a way to get this result without iterating through the entire collection of letters to see if it contains the mouse location? Like can I attach some kind of mouse listener to each letter or something like that? The following program just demonstrates how I create and display the letters I haven't really had a chance to create a demonstration of how they would grow when hovered over. The program i'm working on that actually demonstrates this is very large and hard to trim down to show an example so the following code is actually from a previous question I asked and was provided by Aephyr. Thanks in advance for your guys help :)

                    Rectangle rec = new Rectangle(l.x+l.xoffset,l.y+l.yoffset,l.width,l.height);
                    if(rec.contains(new Point(e.getX(),e.getY()))&&l.resizing==false&&l.defaultSize==l.font.getSize()) {
                        l.resizing = true;

                        l.resizeLetter(l.text);
            }However I just learned that this loop itself is taking up a huge amount of memory by saying
l.font = new Font(l.font.getName(),l.font.getStyle(),l.defaultSize); When I take that line out the lag is reduced by a lot. Also I think that it isn't forgetting the "old" letters font that it is replacing by saying new Font() and after running this loop once my program runs slow and laggy as if it doesn't have enough memory to run fast anymore. Is there something I am doing wrong by initiating a new Font. I would have thought that it wouldn't take up anymore memory because it replaces the old font the the letter "l" has. The loop seems to have some kind of memory leak if someone could point it out to me that would be great. Thanks :)

How to default distribution account through purchase requisition, selecting the project expenditure type

Dear All,
How to default distribution account through purchase requisition, selecting the project expenditure type
Thanks
Abdul.

Hi Abdul,
If you meant defaulting Purchase Order distribution accounts from the (backing) requisition, then the accounts from requisitions will default into the autocreated PO.
If you seek to default distribution accounts for Purchase Requisition using Projects, then the account generator need to have customized rules defined to default account for project enabled distributions based on the Project/Task/Organization/Expenditure Type/Date combination entered.
This note is an extract from the user's guide, and has good detail on defaulting rules of accounts for Purchase Documents:
How Does The Account Generator Default The Accounts In Oracle Purchasing? (Doc ID 1067139.1)
Hope this helps.

Concurrent modification exception while iterating through list

Hi,
I have a list of objects. I use for each loop in java to iterate through that list of objects and display them.
The problem is that while iterating other thread can add or remove some objects from that list, and I get ConcurrentModificationException.
How can I handle this problem. How can I be sure that I am iteration through the updated list.
Thank you

Synchonize on the list before iterating through it, and make sure that other code also synchronizes on the list before adding to it or removing from it. Using a list implementation that simply synchronizes all the methods (e.g. Vector) will not do that, you have to do it yourself.

Iterating through View Object RowIterator Bug.

I use this code to loop through the rows of a view object (As described in javadoc of RowIteratior).
public String checkIterations() {
String res = "Iterated through : ";
RowIterator view = this.getDepartmentsView1();
view.reset();
Row row;
while ((row = view.next()) != null) {
System.out.println("rownum: " + row.getAttribute("RowNum"));
res += row.getAttribute("RowNum") + " ";
return res;
Yet this code never goes through the first row if the executequery has been performed for view object.

Plz suggest me the way to proceed.

Iterating through a generic list of unknown type

Hi,
I am in the process of creating pdf reports for my project.I have to deal with a persistence api to get the data for the report.The data will be in the form of a list,like List<SomeObject>,all these lists returned by the persistence framework contains object of some type which implements a common interface.But through that interface I wont be able to get all the data for my reports.So I am looking for a generic way for iterating through the list,by providing some metadata for the data within the list. I am planning to use reflection to query through the list.Is there any feature of generic,through which I can easily iterate through this unknown type,preferrably a combination of reflection and generics,I want to reduce the LOC.Any suggestions??

If the List returned by the framework isn't parameterized, Like
public List<K> getList(Class<K> classType);
then you have to cast it to the appropriate type. If you are not sure about the type of the Objects in the list, and you have a bunch of class types you could expect from the list, then you could use instanceof operator.
If it could be Class A or B, then
if (obj instanceof A){
A castObject = (A) obj;
else if(obj instanceof B){
B castObject = (B)obj;
}Even to do reflection to invoke methods, you need to know the method Names. Which tells me you have the knowledge of what could come out of the list. So cast them. Invoking methods using reflection is really slow.

Iterating through entrys of HashMap

I have a HashMap that is already populated. I'm iterating through the entrySet and want to get the keys and values and use them to create another object. I've searched the forum and googled but can't quite seem to find what I need. Here's the code I have so far.
Iterator iterator = map.entrySet().iterator();
while (iterator.hasNext()) {
if (iterator.next() != null) {
reasonsList.add(new DropDownData(key, value)); // here's where I'm not sure what to do
}The DropDownData object accepts twos strings, one for the key and one for the displayed value. These strings should be the key and value from my current HashMap entry. But I can't seem to figure out how to do it.
thanks for any help/suggestions

iterating over the not-null entries or iteratingover
gotten entries that are not null is equivalent,maps
return "null" for unexisting keys...
I do not understand what you are saying here.
It is not required that Map implementations return "null" for non-existent keys.
It just happens to be the way the implementations in the JDK are implemented.
The documentation specifically says that Map.get(key) could be allowed to throw a NullPointerException.
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Map.html#get(java.lang.Object )
>
I would add that map's structure suggests it's the
way to go (I mean, mine of course ;))
That's a matter of interpretation.
what's the point in iterating over the values when
you need the key ?When you need the keys and the values (as in the case of the OP), then there is plenty of point in it.
>
the only way (the API should define) to iterate over
a map is through the key (hence the "map" name),
entrySet is (as far as a I reckon) a twisted bypass...It's in the API. It works well. It's useful. So there's no reason not to use it when it is applicable.

Parsing Through the Multi Selection Values in a PL/SQL Procedure

Greetings,
This should be an easy one for one of you PL/SQL experts. I'm not, so I am unsure how to code this up.
I have a Multi Selection page item and am passing the value of it to a PL/SQL routine as a parameter. I am able to use the value if I only pass my procedure one value, so I have it working. Just not with multi-values I need the code in the procedure to loop through the values. How do I code that up? The procedure is relatively short and is included below. p_cell is the multi-value parameter.
Oh yes... You probably need to know this. The values are coming in like this - 1-3:2-3:3-3:5:6
Also, the values are the x-y coordinates of a grid I have over an image on the page. The routine removes certain cells (1-3, etc.) from the grid. The grid is created using HTML, so I have to remove lines of HTML to remove a cell from the grid. Just in case that is helpful.
Thx, Tony

Not sure I understood your need, but it sounded like you need to unscramble a string into a set of rows. If so, I would give you 2 ideas:

2. Other ways (Regular expression or XML): http://apex-at-work.blogspot.com/2011/05/two-ways-using-string-to-table-in-apex.html

I guess i have to first iterate through BKPF and get those documents that lie in the given range, then i 'll have to iterate through the selected documents in BSEG and pick out the vendor line items (KOART = 'S'). Will i be using GET for this..
Is this the right way? secondly, if yes, can sumone show me how to iterate through BKPF and BSEG and get vendor details.?
Thanks..

Hey,
Instead of selecting data from BKPF-BSEG you could use BKPF-BSIK-BSAK.
BSIK and BSAK have the same details as BSEG and are use by SAP for reporting purposes.
Similarly for customer the table are BSID, BSAD and for GL the tables are BSIS and BSAS.
BSIK will have the open items and BSAK will have the cleared items.

Iterating through List View Items using Group By and Jquery

In my listview to my document library, I am using grouping. For each group (using month), it lists all the documents pertaining to that particular month.
Using JQuery, I need to go through each item and parse them, but I'm having trouble finding a usable selector for the for/each function. My parsing code (JQuery) works, but since it uses the class of the table cell with a child anchor, it basically
finds the first item and then all the subsequent file names are named the same (instead of different names, like it should be).
Here's my current code that doesn't work (only the iteration and naming separately for each file - the parsing I'm doing seems to work):
$(".ms-wpContentDivSpace" ).each(function( index ) {
var val=$(".ms-vb2 a").html();
var val2=val.replace(/_/g," ");
$(".ms-vb2 a").html(val2);
any ideas?

That's because
$(".ms-vb2 a").
is bringing back all the pieces that have that class with an anchor on the whole page, not just the ones in the .ms-wpContentDivSpace
I don't know the exact syntax, but I think you need to iterate through all the '.ms_vb2 a' items as well - there are multiple ones, and do something like this inside your other grouping
$(".ms-vb2 a").each(function(index) {
    var val=$(this).html();
   var val2=val.replace(/_/g," ")
   $(this).html(val2);
That's not quite right but maybe that will help.

Yet another Try Catch question. Iterating through a ForEach loop

Confused on error handling in a Powershell ForEach loop. I’m looping through a list of registry keys, attempting
to open each one. If it succeeds, I do a bunch of stuff. If it fails, I want to skip to the next iteration.
If I was doing It in VBScript I’d do this:
For Each Thing In colThings
Open Thing
If Err.Number <> 0 Then
“oops”
Else
Do stuff
Do stuff
Do stuff
End If
Next
This is what I came up with in PowerShell. It seems to work, but just doesn’t seem powershell-ish. There must be a better way to use the catch output than just creating a $return variable and assigning it success or fail?
ForEach ($subKeyName in $subKeyNames)
try{$subKey = $baseKey.OpenSubKey("$subKeyName")}
catch{$return = "error" }
If($return -eq "error" )
“Oops”
Else
Do stuff
Do stuff
Do Stuff

I totally get what you're saying about formatting. I don't' have any habits yet, since I've only been working in Powershell since... well, what time is it now?
Unfortunately, It Has Been Decreed that we are no longer to use VBScript for any engineering solutions at work, so my 15 years experience in it now needs to be transitioned over asap. I don't have the luxury of crawling before I run. I'm trying not to be
frustrated, but it's like an English major waking up one day and being told "You must now speak French exclusively. Here's a book."
The Do Stuff example of my ForEach loop is about 50 lines of code involving matching values in subkeys of this registry key with another and collecting output. I tried wrapping the whole thing in a try section based on some examples, but it seemed odd, that's
why I'm asking. I'm used to tightly focused error handling at the point where an error may occur.
In this example I'm only interested in whether or not I can open the subkey (it exists, but I may not have permission). If I can't, there's no point in continuing with this iteration of the loop, I want to skip to the next one. So why include all the "Do
Stuff" in the the try section? From a readability viewpoint, it doesn't seem helpful.
Also, there may be more error handling deeper in the code. If I then put that in a try/catch, and then something else inside that, now I have nested try/catches mixed in with nested if/elses, all wrapped in a For loop.
Again, I can see how it works logically, but for readability not so much, and having all these braces 50 lines apart to match up is giving me eye strain :).
It sounds like David is agreeing with jrv, that putting the entire ForEach loop code into a try/catch is the conventional way to do it. I guess it makes as much sense as putting it all in an If-else-Endif, and I just need to adjust my paradigm.
But if not, my specific question was more along the lines of, is there a built in way to tell that the catch section has been executed, rather than me using it to populate an arbitrary variable and then read it? In VBScript, you execute something, and the
next line, you check the Err.number. I wasn't sure if you could do that with a try/catch.

Problem in iterating through huge number of entries ... memory issue

I am having large number of entries in lacs.
I need to check each entry with previous ones , so I need to iterate through the each and every entry previous to current entry.
Here I have put all the entries in arraylist and I am iterating though this arraylist and validating current entry.
As I am using the arraylist for storing all the entries , the system is taking lot of memory because I am putting all in the memory.
Is there anyway to resolve this memory issue?

If you have a hundred thousand entries, to verify all the entries you would need to compare the later entries with the earlier ones such that:
Entry 1 = 100,000 accesses
Entry 2 = 99,999 accesses
Entry 5 = 99,995 accesses
Entry 10 = 99,990 accesses
Entry 99,990 = 10 accesses
Entry 99,995 = 5 accesses
Entry 99,999 = 1 access (only to be compared with the 100,000th entry)
It would then make sense to keep a certain (fixed) amount of entries in memory, those which get accessed the most, then write to file those which get accessed the least frequently. Have a method that can decide, based on the index of the entry, whether to get it from the ArrayList or to read it from the file. That will give you good performance.
BufferedReader would be a good candidate to read the file, because it can skip more bytes at once should you need a line very late in the file. Also consider using RandomAccessFile and seek(entryNumber * ENTRY_SIZE) if your data can be represented with a fixed size in bytes.
