Restricting the item data for two pages if data is more then cutoff

Hi Expers,
I have one requirement that i need to restrict item data upto two pages .If more data is vailabe even pritning after two pages then data should cutoff(means we don't want to print that extra data in the next pages ).Could you please explain how can we achive this in main window ?Can we achive this even using secondary window also?Thanks for your help in advance.
Thanks and Regards,
Venkat

Dear experts,
For restricting the data up to two pages in the mainwondow ,I have written the condition SFSY-PAGE LE 2.But still i am getting more than two pages means entire data.Can any one explains why this condition is failed(My main window is in the first page itself).
Many thanks for your help,

Shared variable, missing data, the same timestamp for two consecutively data

hello
I have a problem with missing data when I read from a network published shared variable.
Host VI:
In a host VI on my Laptop (HP with WinXP Prof.) i'm writing data to the shared Variable "data". Between two consecutively write operations is a minimum of Milliseconds waiting time. I use that because I want to be sure that the timestamp for each new data value is different then the preview one (resolution shared variables is 1 ms)
Target VI:
the Target VI on a cRIO-9012 realtime device is reading only new data in the way that it compares the timestamp of a new value with the timestamp from the last value.
Problem:
rarely, I'm missing a datapoint (sometimes everything works fine for several hours, transferring thousands of data correctly before suddenly the failure happens). With some workaround I'm able to catch the missing data. I've discovered that the missing data has the exactly same timestamp then the last readed datapoint, therefore is ignored in my "legal" data.
To sum up, the missed value is written to the shared variable in the host, but the target ignores him because his timestamp is wrong, respectively the same as the last value has, despite the host waits every time for a minimum of 10 milliseconds before writing a new value.
Note:
The shared Variable is hosted on the Laptop and configured using buffering.
The example is simplified only to show the principle function, in real I use also a handshaking and I secure that there is no over- and underflow.
Simplified Example:
Question:
Has someone an idea why two consecutively data can have the same timestamp ?
Where is the (wrong) timestamp finally coming from (system?) ?
What would be a possible solution (at the moment with shared Variables) ?
-> I tried a workaround with clusters where each data gets a unique ID. It works but it is slower than comparing timestamps and I could get performance problems.
Would it change something when I host the shared Variable on the RT-System ?
Thanks for your help

Reto
Solved!
Go to Solution.

Hi Reto,
I had a look on your modified Example.
Because the Shared Variables didn`t work like Queues or Notifiers (No Event or Interrupt when a new value has been written. And for sure the´re not possible over a network) you will see the issue, that the code is reading the values more often with the same timestamp (Polling Problematic) if the reader is faster then the writer. And because the timestamp is written with the value you´re able to program like you do. Filter out whats duplicated when you have the same timestamp.
Everything is described in here:
http://zone.ni.com/devzone/cda/tut/p/id/4679#toc1
Laurent talked about a second depth of buffer. Please have also a look at the link. Somewhere in the middle of the tutorial you see the explanations of Buffer and RT-Buffer.
Regarding your question: Would it change something when I host the shared Variable on the RT-System? --> No
In my experiences, you should consider to place the Shared Variable Engine after asking some questions regarding the application.
You will find the Answers to this 3 Questions also in the link:
Does the application require datalogging and supervisory functionality?
Does the computing device have adequate processor and memory resources?
Which system is always online?
And you`re right the smalles time interval you can see in the timestamp is 1ms.!
What you also can do is working with an enabled "timed out". This might be more performance efficient than reading the timestamp.
What I don`t know and not find up to now, is if LabVIEW or the OS adds the timestamp. It´s taken from the system time, this looks like LabVIEW is taking the value and adds it.
I hope this helps

Different Pricing date for two line items

Hi guru's
How to give different pricing dates for two line items
in a sales order
To elaborate
I have two line items one i need pricing date order date
second one i need pricing date should be delivery date
Thanks in advance
Srinivas

Dear Srinivas,
While creating sales order select the item which you want to change the pricing date then go to menu>GOTO>Item -->Click on Sales A here you can able to change the pricing date as you like.
You can change the pricing date of the item in the sales order through sales order change mode but that sales order should be open.
I hope it will help you,

The bookmarks toolbar is there but has no item buttons on it. How do I get the items back for this toolbar? Also would like to know if the toolbars can be put on the same line to make more room on the page (drag & drop) ??

The bookmarks toolbar is there but has no item buttons on it. How do I get the items back for this toolbar?
Also would like to know if the toolbar can be put on the same line to make more room on the page (drag & drop) ?? Like the menu & bookmarks toolbar could/should fit on same line. This would add more page view...
Floyd Perry
Thanks

Check that you still have the "Bookmarks Toolbar items" placed on the Bookmarks Toolbar
* Make sure that you have the "Bookmarks Toolbar" visible: "View > Toolbars"
* Check in "View > Toolbars > Customize" that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
* If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the Customize window onto the Bookmarks Toolbar
* If you do not see the "Bookmarks Toolbar items" then click the "Restore Default Set" button
You can only move the content from a toolbar onto other toolbars if all toolbars support that feature. You need to check that in the options of each toolbar.

SharePoint Error "The security validation for this page is invalid" when delete an item

Hi,
I have SharePoint 2010 setup and works fine until today all of a sudden it throws error "The security validation for this page is invalid" when delete a SharePoint document or list item.
There is no custom event handler deployed on library/list, and it should not be account issue as the same account works yesterday, and even after I turn off security validation from Central Admin, it still doesn't work.
The only change I did is turn off Dynamic Compression from IIS, after that I tried enable back Dynamic Compression but it still doesn't work.
Does anyone know what could be the possible reasons? Thanks in advance.

hi,
in the page just try to make this :
<SharePoint:FormDigest runat="server" />

Nope, I doubt it. As I said:
I disabled Aero theme, checked font scaling was 100% and rebooted Windows in between all of the steps to no avail.
I've been reading a lot around this and it seems the arrow key problem is a red herring; I think it's just some kind of terminal preferences corruption.

Update list item with managed metadata field returns The security validation for this page is invalid

Using SharePoint 2010 Server
I'm attempting to programtically update a managed metadata field in a document library. I'm able to do it without issue on all other non-managed metadata fields. When I attempt it on a MM field I get the error message
"The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again."
After some digging I realised that this error was being caused because SharePoint was trying to write to the TaxonomyHiddenList list (../sites/mysite/Lists/TaxonomyHiddenList/AllItems.aspx)
When I update a document through the browser with a term (Term01), it shows up in this TaxonomyHiddenList . I can then run my application, apply Term01 to my new document and it works fine. But if I apply Term02 to my new document it gives me the error above.
Summary
My app can read the TaxonomyHiddenList fine but it can not perform an operation that would write to it, resulting in not being able to update the MM field.
Question
Is there any advice on how I can further debug this issue?

Hi,
According to your post, my understanding is that you want to update managed metadata field in document library programmatically.
I have made a simple code demo below to updata managed metadata field in document library, it works like a charm, you can refer to it.
public static void UpdateMSField()
using (SPSite site = new SPSite("http://YourSiteURL"))
using (SPWeb web = site.OpenWeb())
//SPList list = web.Lists.TryGetList("Libs_1");
SPDocumentLibrary lib = (SPDocumentLibrary)web.Lists["Libs_1"];
// No point in proceeding if we can't find the list
if (lib != null)
// add a new item
// SPListItem item = list.AddItem();
SPListItem item = lib.GetItemById(1);
//Console.WriteLine(item.Name);
// get the current taxonomy session, which wraps up all of the
// associated TermStore objects for this SPSite object
TaxonomySession metadataService = new TaxonomySession(site);
// get the taxonomy field
TaxonomyField taxField = item.Fields["MMS_1"] as TaxonomyField;
// get the term store associated with the taxonomy field
TermStore termStore = metadataService.TermStores[taxField.SspId];
// get the actual term set associated with the taxonomy field
TermSet termSet = termStore.GetTermSet(taxField.TermSetId);
// search for the terms we wish to set the field to
var terms = termSet.GetTerms("term_1", true, StringMatchOption.ExactMatch, 1, false);
// if we have found a term populate the field
if (terms.Count > 0)
// set the field to the term(s) we have found
taxField.SetFieldValue(item, terms.First());
// Update the item
item.Update();
Console.WriteLine("success...");

My new Ipad2 got connected to my home Wi-Fi and to the network and for 2 days everything was alright. Then I encounteed a problem. Though my Ipad2 was getting connected to Wi-Fi, could'nt access network. How to enable Data Roaming?.

My new Ipad2 got connected to my home wi-fi and to the network. For 2 days evrything qored well. Then though Ipad2 was connected to wi-fi, it did not open the web page/s. The dialogue box read, `Data Roaming is turned off. You can enable Data Roaming in the Network Section of General Settings' When I tried it, there is no item of Data Roaming displayed in the Network Section of General Settings. It shows only two settings. 1. VPN and 2. Wi-Fi. How to correct this issue? Help is needed to resolve this issue. I am from India and Apple do not have any local service providers.Pl. help me.

Sounds like the WiFi is connected, but cannot reach the Internet and is trying to use 3G, but you are in a roaming area so you get the dialog.
The first thing to try is turning the Wi-Fi off and back on again in Settings. Or simply turn the iPad off and back on again. If that doesn't work double-check that other devices are able to use the same WiFi network successfuly, or try the iPad on another WiFi network.

Restrict the items while adding to cart based on zipcode.

Hi All,
I have a requirement of restricting the items while adding to cart based on the zipcode .
For ex . If I enter zipcode of 10014 ,then I shld able to only add 2 items .If i enter some other zipcode like 55344 then I shld able to only add 5 items .
Please help me to implement this scenerio.
Advance thanks

You can add a property in catalog for "Product" item-descriptor to refer to "ZipCodeQuantity" item-descriptor to define the restriction. This way even if the quantity for a particular product( for a particular zip) changes, it becomes easy.
zipcodeQuantity will have productid, zipcode, quantity allowed.
Use a droplet to show only the allowed quantity for a particular product for a particular zip code in product detail page. This way you can restrict them from adding in ProductDetail page itself.
Just an another way.

How do I restrict the items shown in Action pull-down list in Quote Overiew

I would like to restrict the items shown in the pull-down list of Actions in Quote Overview Screen in Oracle Quoting (HTML)
The list is defined as part of Quick Codes (Lookup_type = ASO_QUOTE_ACTION). Per my understanding, it should show up all the lookup values enabled in ASO_QUOTE_ACTION. But I see only a few of those enabled in the action drop-down list in Overview Screen.
I appreciate if any one can provide any clue where they are restricted.
To access ASO_QUOTE_ACTION Loookup code, here is the navigation path.
® Quoting Sales Manager → (N) Setup → Quick Codes and query for ASO_QUOTE_ACTION.

The security validation for this page is invalid – Infopath 2010

Hello Experts,
I have created browser enabled Infopath form and written a custom code (infopath 2010). I have a “Save” button on a form that submits the data into multiple relational sharepoint list. While debugging through VSTA everything goes well and successfully submits
the data, but after publishing a form(browser enabled) I am not able to save a data to sharepoint list. When I Clicked on save button, it just refreshing a page, even the same was getting after
made it to full trust and approved by Admin.
Before this I was using “Submit” button to submit a form, that time I was getting a popup with the message “There has been an error while processing the form”. And in log files it was showing error message as “The security validation
for this page is invalid”.
I referred many blogs regarding validation error and tried almost everything in every way, some of shortly mentioned below,
Formdigest (It not works for me)
Security Validation (It works perfectly)
The second option is working for me. (But this is not a good practice and also not recommended)
Just want to know “Without making Security Validation Off” how can I resolved this validation issue from infopath 2010 form.
Please share your thoughts on this. Any help is appreciated.
Regards,
Uday

Hi Uday,
Have you tried SPWebapplication.FormDigestSettings.Enabled = false to turn off the digest setting property for the web application? See this blog for the details.

JavaScript - Error: The security validation for this page is invalid...

Hi there,
I have a question regarding javascript and the security validation.
I have created a custom action for a document library. This custom action should update a field in all selected documents by the user. But when I do the update, I got this error message:
"The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again."
I know, I could AllowUnsafeUpdates, if I were using C#, but actually I can only use JavaScript at this stage. Or does anybody know, how to allow this or switch to C# in this area?
Here is my custom action:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomAction
Id="GrolmansJavaScriptFile"
ScriptSrc="~site/_layouts/SharePoint-Z-Drive-Project/gg1855.js"
Location="ScriptLink">
</CustomAction>
<CustomAction
Description="Approve Documents"
Title="Approve Documents"
Id="RibbonDocumentsManageApproveDocuments"
Location="CommandUI.Ribbon"
RegistrationId="10000"
RegistrationType="List"
Sequence="0"
xmlns="http://schemas.microsoft.com/sharepoint/">
<CommandUIExtension xmlns="http://schemas.microsoft.com/sharepoint/">

<CommandUIDefinitions>
<CommandUIDefinition Location="Ribbon.Documents.Manage.Controls._children">

</CommandUIHandlers>
</CommandUIExtension>
</CustomAction>
</Elements>
And here is my JavaScript code file:
function ApproveDocuments()
var siteUrl = '/';
var clientContext = new SP.ClientContext(siteUrl);
var currentlibid = SP.ListOperation.Selection.getSelectedList();
var currentLib = clientContext.get_web().get_lists().getById(currentlibid); //Gets the current Library
var selectedItems = SP.ListOperation.Selection.getSelectedItems(clientContext);
for (var i in selectedItems) {
currentLib.getItemById(selectedItems[i].id).set_item('DocumentStatus', 'Approved');
currentLib.getItemById(selectedItems[i].id).update();
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded()
alert('Document approved:' + newListItem.get_id());
function onQueryFailed(sender, args)
alert('Document approval failed: ' + args.get_message() + '\n' + args.get_stackTrace());
Any idea, how to perform the update on the selected items?
Thanks for any hint.
Dennis

Ok, I found the reason.
I just had to replace the SP.ClientContext line in JavaScript.
Instead of
var clientContext = new SP.ClientContext(siteUrl);
I need to use this one:
var clientContext = SP.ClientContext.get_current();

Using Liquid, what is the best practice for handling pagination when you have more than 500 items?

Right now I can only get the first 500 items of my webapp, and don't know how to show the rest of the items.
IN MY PAGE:
{module_webapps id="16734" filter="all" template="/Layouts/WebApps/Applications/dashboard-list-a.tpl" render="collection"}
IN MY TEMPLATE LAYOUT:
{% for item in items %}
<tr>
<td class="name"><a href="{{item.url}}">{{item.name}}</a></td>
<td class="status">Application {{item.['application status']}}</td>
</tr>
{%endfor%}

<a href="{{webApp.pagination.previousPageUrl}}">Previous Page</a>
Current Page: {{webApp.pagination.currentPage}}
<a href="{{webApp.pagination.nextPageUrl}}">Next Page</a>

The security validation for this page is invalid

I am trying to declare items in doc library inside a specific folder as records. This is my code:
using (SPWeb site = SPContext.Current.Site.OpenWeb("myClassicSite")) {
                    site.AllowUnsafeUpdates = true;
                    SPList list = site.Lists.TryGetList(currentDocLibName);
                    SPFolder folder = list.GetItemById(foldId).Folder;
                    try {
                            SPDocumentLibrary doclib = (SPDocumentLibrary)site.Lists.TryGetList(currentDocLibName);
                            SPView defaultView = doclib.Views["my custom view"];
                            SPListItemCollection docColl = doclib.GetItemsInFolder(defaultView, folder);
                            foreach (SPListItem item in docColl) {
                                Records.DeclareItemAsRecord(item); // throws exception here
                    } catch (Exception) {
It throws exception: "The security validation for this page is invalid"
I just can't declare items as records, I tried RunwWithElevetedPriviledges, AllowUnsafeUpdate, and SPWebapplication.FormDigestSettings.Enabled = false;
What am I doing wrong?

Have you tried adding SPUtility.ValidateFormDigest(); before the start of your code section? Have a look at the article below for more info on the same.
http://blogs.technet.com/b/meamcs/archive/2011/04/04/troubleshooting-sharepoint-error-the-security-validation-for-this-page-is-invalid.aspx
The problem should be originating because of the use of AllowUnsafeUpdates in your code above. Here is a good writeup on best practices when using AllowUnsafeUpdates in the code:

If column2 is same for two different column1 data

I have a table say XYZ like this
COLUMN1 COLUMN2
A     B
C     B
N     X
HJ     X
I want to print if column2 is same for two different column1 data
I want to print that rowids
Please help me in this

That's the same as I thought, but then I realised that this might result in some false positive rows.
What if column1 has also the same value for some of the rows in which column2 is the same?
If the following is your data set, what rowid's should be displayed?
row column1 column2
1        A       S
2        B       S
3        C       T
4        C       T
5        D       U
6        D       U
7        D       V
8        E       W
