Allowing only pdf files in document library using Javascript

HI,
I have a document library in sharepoint 2013, where i want only pdf files to get uploaded in it. I have created event receiver for the same and it is working fine. but i want to restrict the files using javascript on
the page itself, since, In event receiver, after the file is getting uploaded, it is checking and throwing error. So, is there any way to check for the file type before uploading the file and show error message if wrong file is uploaded?

Hi TanPart,
I have changed the code which you have give in order to get the files from SharePoint 2010 Foundation Document Library.But i am getting below error in powershell.
Property 'ListItemCollectionPosition' cannot be found on this object; make sure it exists and is settable.
Could you tell me which is the issues in it?
See the code below.
$web = Get-SPWeb http://ntmoss2010:9090/Site
$list = $web.Lists["DocLib"]
$query = New-Object Microsoft.SharePoint.SPQuery
$query.ViewAttributes = "Scope='Recursive'";
$query.RowLimit = 2000
$caml = '<Where><Contains><FieldRef Name="Title" /><Value Type="Text">Process Documents/Delivery</Value></Contains></Where>' +
        '<OrderBy Override="TRUE"><FieldRef Name="ID"/></OrderBy>'
$query.Query = $caml
do
    $listItems = $list.GetItems($query)
    $spQuery.ListItemCollectionPosition = $listItems.ListItemCollectionPosition
    foreach($item in $listItems)
        #Cast to SPListItem to avoid ambiguous overload error
        $spItem = [Microsoft.SharePoint.SPListItem]$item;
        Write-Host $spItem.Title
while ($spQuery.ListItemCollectionPosition -ne $null)

Unable to add aspx file to document library using REST and JSOM in SharePoint Hosted App

Hi,
I am unable to add an aspx file to document library. I was actually trying to create a WIKI page and upload to Pages library but that wasn't working so I tried simple document library. It keeps failing with Access Denied error. I have checked
the blocked types and aspx is not included. I can upload it directly from the browser so that shouldn't be the case. I have read that it can be achieved with CSOM but I need this to work with a SharePoint Hosted App. Here is my JSOM:
factory = new SP.ProxyWebRequestExecutorFactory(appweburl);
context.set_webRequestExecutorFactory(factory);
appContextSite = new SP.AppContextSite(context, hostweburl);
oWeb = appContextSite.get_web();
oList = oWeb.get_lists().getByTitle('Documents');
fileCreateInfo = new SP.FileCreationInformation();
fileCreateInfo.set_url("mywiki.aspx");
fileCreateInfo.set_content(new SP.Base64EncodedByteArray());
fileContent = "<%@ Page Inherits=\"Microsoft.SharePoint.Publishing.TemplateRedirectionPage,Microsoft.SharePoint.Publishing,Version=15.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c\" %> <%@ Reference VirtualPath=\"~TemplatePageUrl\"
%> <%@ Reference VirtualPath=\"~masterurl/custom.master\" %>";
for (var i = 0; i < fileContent.length; i++) {
fileCreateInfo.get_content().append(fileContent.charCodeAt(i));
newFile = oList.get_rootFolder().get_files().add(fileCreateInfo);
context.load(newFile);
context.executeQueryAsync(function () {
alert('yo');
}, function (sender, args) {
alert(args.get_message() + '\n' + args.get_stackTrace());
If I change the file extension to "txt", it works. Same with REST implementation, it works with "txt" but fails with "aspx". Maybe what I am trying to do will not work using JSOM or REST. Any suggestions? Your
help is always appreciated.

Your code works fine in both my on-premises and SharePoint Online. I have given the app full control, so I suspect this is a permissions issue. I would check your permissions on your appmanifest. Must be something to do with publishing permissions. Try
giving full control and work the permissions down.

Copy Attachments of sharepoint list item to a document library using Javascript on click of a button

The requirement is as follows:
1. We have a SP list. All items in the list have mulitple attachments.
2. On click of a button, All the attachments of all items should be copied to a document library
This is to be done from client side only. No server code is acceptable. We have tried following things:
1. USing Asynch call
context = new SP.ClientContext("my site name");
         this.oWebsite = context.get_web();
         var lists = oWebsite.get_lists();
         var list = lists.getByTitle('my list name');
         context.load(oWebsite);
         var folderPath = 'Lists/<my list name>/Attachments/' + folderId;
         var Folder = oWebsite.getFolderByServerRelativeUrl(folderPath);
         context.load(Folder);
         Files = Folder.get_files();
         context.load(Files);
         context.executeQueryAsync(Function.createDelegate(this, this.ExecuteCopyOnSuccess), Function.createDelegate(this, this.ExecuteCopyOnFailure));
function ExecuteCopyOnSuccess(sender, args) {
         for(var p=0;p<this.Files.get_count();p++)
     var file = Files.itemAt(p);
          var filename = file.get_name();
          if (filename != null) {
              var newUrl = 'document library url';
              file.copyTo(newUrl, true);
              context.executeQueryAsync(null,null);
In this case, Files.get_count() throws error - The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.
2. Using copy.asmx service
It copies files to document library but some files are blank and are having size 0.
Thanks!

Hi,
I think you can use Document Content types or document sets -
Here are links that you can refer to

Can't open Acrobat pdf files in document library - SBS 2011

I've uploaded some Acrobat PDF files to a document library in the companyweb (SharePoint 2010 Foundation website) on SBS 2011. But if I click on one of them in the standard view, acrobat opens and displays a message “The URL you have provided could not be
reached. Please verify that the URL is correct and that the network location is reachable.” I'm using Acrobat Reader XI 11.0.2 and Internet Explorer 10.
I have tried a few suggested solutions, eg to edit the docicon.xml file to include <Mapping Key="pdf" Value="AdobePDF.png" OpenControl="AdobeAcrobat.OpenDocuments"/>, check that the WebClient service is running, and
Use Remote Interfaces permission is set on the SharePoint site. But no luck.
I don't know if this is a problem with SBS 2011, or Acrobat, or Internet Explorer. Interestingly the pdf opens OK in Chrome. It looks like it is trying to edit the document instead of open it in the acrobat reader.
Anyone know of a solution?

I have found one possible solution. In my case the site was brought into Sharepoint Foundation 2010 as a migrated site from a previous SBS installation.
The site was imported as http://servername and the IIS site had a host header with companyweb so that users could browse to it, and all references to the site were as http://companyweb
All my attempts to open the PDFs were using the http://companyweb URL.
I was researching the issue and had gone through everything, but one thing got me thinking when some sites suggested that I look at the permissive or strict browser file open settings. I looked at the web application and it was set to http://servername in
the Central Administration site. I thought hmm let's try opening the Adobe PDF docs with that URL instead, and it worked!
So I changed the web application URL to http://companyweb and tried again and hey presto it's now working.
I really hope this helps someone, it took me a good couple of hours of my day researching to find the solution here.
Some extra info: we are using Adobe Reader 11.0.6 with IE11. Testing with Firefox worked, but that opens the document by downloading it locally and then using Adobe Reader. fix The above actually resolves the problem, it's nothing to do with permissive or strict
file open settings, I set the SP site back to strict and PDFs still open fine.

Schedule the Publishing date of a file in Document Library using CSOM

I am having a hard time to schedule the publishing date of a document uploaded to a sharepoint document library. Basicaly, what I want is to upload a file to a document library and to schedule it´s publishing for a future date, using CSOM. Then someone should
approve this (file content and scheduled date and time for publishing).
I am able to upload the document to the document library and to start the approval workflow automatically (when the document is uploaded), but I don´t know how to set the publishing date using client side object model.
Apparently all I need to do is to set up the properties ScheduledItem.StartDate and ScheduledItem.EndDate, but I just can´t manage to do it. Any help will be very much appreciated.

Convert PS to PDF file in Adobe Distiller using javascript

Hi scripters,
I have created some PS files from Indesign using javascript. Files are d:\test\1.ps,2.ps
Now I want to convert this ps files into pdf files uisng javascript?(I am not comfort to use export as PDF option for this job)
how I can do this?
Thanks in advance
regards
a r u l

Hi arul
Firstable, you may not need to create PS files as Indesign is able to produce PDF files natively. I was told that it was more reliable to do so using a certification profile such as PDFX.
You will find a lot of PDF export script everywhere.
However, if you want to go that way (PS to PDF). I did that once.
First you determine into distiller a hotfolder where you ps files wille be generated. Then in the hotfolder options, you precise the profile you want to use. Otherwise, distiller may be using low quality PDF as default and your PDF may not be as good as you want.
var distiller = File("c:/xxx/yyy/zzz/distiller.exe"); //the path to your distiller app.
distiller.execute();
Here you are !

Download older version of a file from SharePoint Document Library using CSOM and 404 error

Hi,
I am trying to download previous versions including Major and Minor versions of documents from SharePoint Online using CSOM. I get 404 error when I try to download the file. I found several posts on various discussion forums where people are getting same
error but none of those have any solution/answer. Below is one of the threads and sample code I have tried that results in 404 error. If I use the link in browser directly, I am able to download the file. Also I am able to download the current version of file
using CSOM without any problem, it is only the older versions that give me 404 in CSOM.

clientContext.Load(site);
clientContext.ExecuteQuery();
File file = site.GetFileByServerRelativeUrl(“/Shared Documents/mydocument.doc”);

Unable to edit .vsdx visio file that is inside a document library using visio 2010 sp2

I have Visio 2010 SP2 installed locally inside my machine. The current version can open vsdx files by doing some conversions. I got the following scenario inside my SharePoint server 2013:-
Currently I have Visio file (with .vsdx extension) uploaded to my SharePoint 2013 document library.
If I click on the Visio file I got the following dialog.
I select “Edit”, click on ok.
Then the visio 2010 application will convert the current file and open it locally inside my machine.
But the opened file will have it name as “Copy (1) of ….”, as follow:-
So if I do some changes to the Visio file and I click on save I will not be able to save my changes back to the SharePoint server’s document library. Now if I do the same steps for a .vsd file not .vsdx then I can directly open the Visio file (without any
conversion process) and I will be able to save my changes back to SharePoint server.
So can anyone advice how to be able to edit .vsdx files which are uploaded to SharePoint document library using visio 2010 SP2 ?
Thanks

Thank you for your ideas.
After that last posting, but before your response, I asked them to add the local farm to their trusted sites zone. Several blogs I had encountered while searching had listed that as something they had tried.
As soon as they added the site to their trusted site zone, the problems went away.
It was definitely not all users - I only had 2 people directly contact me about the issue.
I never got a chance to ask them about other SharePoint sites - they were working on the sites where they spent most of their time - I don't know if they had other sites.
The old location and the new location of these 2 sites are in the same site collection - it was moving them from
http://myfarm/sites/div/dept67/site1
to
http://myfarm/sites/div/dept64/site1
basically (with the actual names changed to protect my job).
The site collection is /sites/div . So the site collection features are the same.
I suppose that the site features could have changed between the export and the import - but since things are working now and I didn't change any features, I don't think that it is.
At this point, things appear to be working. However strange that seems to me.

Not able to copying files/folders from one Document Library to another Document Library using Open with Browser functionality

Hi All,
We have SharePoint Production server 2013 where users are complaining that they are not able to copy or move files from one document library to another document library using “Open with Explorer” functionality.
We tried to activate publishing features on production server but it did not work. We users reported following errors:
Copying files from one document library to another document library:
Tried to map the document libraries and still not get the error to copy files:
In our UAT environment we are able to copy and move folders from using “Open with Explorer” though.
We have tried to simulate in the UAT environment but could not reproduce the production environment.
Any pointers about this issue would be highly appertained.
Thanks in advance

Hi John and all,
One the newly created web applications that we created few days back and navigated to document library, clicked on “Open with Explorer”, we get this error.
We're having a problem opening this location in file explorer. Add this website to your trusted and try again.
We added to the trusted site in Internet Explorer for this web application, cleared the cache and open the site with same document library but still get the same above error.
However, another existing web application (In same the Farm) that we are troubleshooting at the moment, we are able click on “Open with Explorer”, login in credentials opens and we entered the details we are able to open the document
library and tried to follow these steps:
From Windows Explorer (using with Open with Explorer), tried to copy or move a files to
source document library.
From Windows Explorer moved this file to another destination document library and we got this error.
What we have to achieve is users should be able to copy files and folders using
Open with Explorer functionality. We don’t know why Open with Explorer
functionality not work working for our environment.
Are we doing something wrong?
We have referred to following websites.
we hope concepts of copying / Moving files are similar as SharePoint 2010. Our production environment is SharePoint 2013.

When I try to move a PDF file to iBooks the system works for a while...sometimes the file appears and than disappears....sometimes the file never appears. Is ther some limit to the number of books or total storage used in IBooks? Thanks....

Hi jybravo70,
Welcome to the Apple Support Communities!
It sounds like you may be experiencing issues on your non iOS 8 devices because iOS 8 is required to set up or join a Family Sharing group.
The following information is located in the print at the bottom of the article.
Apple - iCloud - Family Sharing
Family Sharing requires a personal Apple ID signed in to iCloud and iTunes. Music, movies, TV shows, and books can be downloaded on up to 10 devices per account, five of which can be computers. iOS 8 and OS X Yosemite are required to set up or join a Family Sharing group and are recommended for full functionality. Not all content is eligible for Family Sharing.

Download files from document library in zip file using javascript

Hi,
I am developing SharePoint Hosted App which needs to download all the files in the document libraries of SharePoint site in a zip folder where in that zip file each document library should be a folder, in that folder the files of that document library will
be shown. Currently I am display all the document library in a table with check boxes as shown in the below figure. Now when user selects the check boxes and click on download button, the selected document libraries along with the files should be downloaded
in a zip folder. This should be achieved through javascript. Can anyone share me the code to solve this problem.
Thanks & Regards,

You can use
zip.js, but the best way - implement your solution on the server-side.

I have a document made up of separate PDF files which reside in a folder and are linked to each other via hyperlinks. Each pdf file is set to open with bookmarks displayed, however if I link from one PDF file to another and use the "Previous View" button

I have a document made up of separate PDF files which reside in a folder and are linked to each other via hyperlinks. Each pdf file is set to open with bookmarks displayed, however if I link from one PDF file to another and use the "Previous View" button to navigate back to my starting point the bookmarks are replaced by "page thumbnails". Is there anyway to stop this from happening?

Hi Pusman,
While setting up the links, if you choose to open the file in a new window then you won't face this issue, then you can simply switch to the previous file and bookmark view will remain as it is.
Does that helps with your query?

C#/REST Getting files in a document library using Internal Name

Hi Folks,
I need to get a list of files in a SP2010 and SP2013 document library using the REST API - this is occurring inside a timer service application so am using C#. As a constraint I need to use the internal names for the document libraries - primarily
because users tend to change the display name and this is an automated service.
When I make a call to _api/web/GetFolderByServerRealitveUrl('/Shared Documents')/Files I get a bunch of XML but how do I get just a list of filename+ext. I am using Xdocument (LINQ to XML). I need to retrieve the name property in the
contents sub element for all files returned.
Second question, how to I change this to use the internal name '/Document' instead of '/Shared Document', so that it copes with users changing the display name of document libraries.
Regards
Andy

Hi Andy,
1.For your issue, you can refer to the code as below:
using System.Xml;
namespace REST_XML_LIST_GET
class Program
static XmlNamespaceManager xmlnspm = new XmlNamespaceManager(new NameTable());
static Uri sharepointUrl = new Uri("Site URL/");
static void Main(string[] args)
xmlnspm.AddNamespace("atom", "http://www.w3.org/2005/Atom");
xmlnspm.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
xmlnspm.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
NetworkCredential cred = new System.Net.NetworkCredential("username", password", "domain");
HttpWebRequest listRequest = (HttpWebRequest)HttpWebRequest.Create(sharepointUrl.ToString() + "_api/Web/lists/getByTitle('List Name')/items");
listRequest.Method = "GET";
listRequest.Accept = "application/atom+xml";
listRequest.ContentType = "application/atom+xml;type=entry";
listRequest.Credentials = cred;
HttpWebResponse listResponse = (HttpWebResponse)listRequest.GetResponse();
StreamReader listReader = new StreamReader(listResponse.GetResponseStream());
var listXml = new XmlDocument();
listXml.LoadXml(listReader.ReadToEnd());
//Method 1 Seperate node list
var titleList = listXml.SelectNodes("//atom:entry/atom:content/m:properties/d:Title", xmlnspm);
var idList = listXml.SelectNodes("//atom:entry/atom:content/m:properties/d:ID", xmlnspm);
int i = 0;
foreach (XmlNode title in titleList)
Console.WriteLine(title.InnerXml+" "+idList[i++].InnerXml);
//Method 2 single node list
var prop = listXml.SelectNodes("//atom:entry/atom:content/m:properties", xmlnspm);
foreach (XmlNode ndlist in prop)
Console.WriteLine(ndlist.SelectSingleNode("d:Title", xmlnspm).InnerXml + " " + ndlist.SelectSingleNode("d:ID", xmlnspm).InnerXml);
Console.ReadLine();
2. For a workaround, you can get the display name based on the internal name and use the display name in the Rest API.
