Digital signature in SharePoint hosted app

I am creating a sharepoint hosted app where user must use digital signature(loginname, password) before submitting request.
I am unable to find any machenism to validate user credentials using jquery/javascript.

Hi,
Check the blog below:
Use tasks to maintain your workflow state. Each approval adds a task for the signer. There is a workflow action to handle this for you. When the task is done, it moves to the next step.
Use the Wait action to have your workflow pause until a change is made. You would have a column for each signer. When the column is filled in, the workflow continues with the email for the next signer.
Have a workflow that runs for each signing step. The workflow will be kicked off on item change. You will need a column for each signer again. The workflow will examine each column in order to determine what stage it is on and then email the appropriate person.

Hope this helps

Hi,
According to your post, my understanding is that you want to enable/disable the custom ribbon button accordingly.
We can use the EnabledScript attributes to achieve this scenario.
The EnabledScript attribute of the CommandUIHandler that will enable or disable the button depending on whether the function returns true or false.
There are some articles about this topic, you can refer to them.

Issue with Workflow in a SharePoint-hosted App Application

Hi,
I have created a Sharepoint-hosted app which has a list workflow in it. After I deploy it to the sharepoint server, I can not find any workflow under the associated list.
However, I did have target list associated with workflow in workflow project property.
(My app and worflow is developed in VS 2012)
I have searched the forum and found some similar question. However, all of them don't have useful answers.....
Can anyone give me some help~?

Hi Baron123,
I can reproduce your scenario, that create an app with list, and add a workflow associates with it, the workflow is not working, that seems doesn’t associates successfully.
Before I can tell why this happens, I found a helpful blog about keeping the list definitions and workflow definitions separate, use Handle APP installed event receiver to wire up a workflow to lists in app web or host web.
As it is not a good solution to deploy the list and workflow in the same app solution, because that if you redeploy the app the date will be lost, the list will be new created, so I would suggest you to reference the blog, check whether this can meet your
requirement.

How to open List when Page loads in SharePoint Hosted App?

I want to create an app same like InstantPracticeManager by InstantQuick.
Now I want to know that in a SharePoint Hosted App How can I show the Whole List in a page.
Here I have added one image:
Here there is one list and there are 4 views of that list.
Now the App will be like when I load the page It will show like the image above. Now how can we show the list like this in sharepoint hosted app?
I want the same scenario which is shown in the following blogs:
http://sp2013.blogspot.in/2012/08/use-list-view-in-sharepoint-2013-apps.html
and
http://www.sharepointnutsandbolts.com/2013/08/working-with-web-parts-within.html
where they add a list to an app
Can any one suggest me the idea? I am bit confused.
thanks in advance.

Hi,
According to your post, my understanding is that you want to show the different list view in a page in SharePoint Hosted App.
We can use jQuery and cross-domain library to achieve it.
The following articles for your reference:

How to get inputted value in a RTE field on custom page and submit by REST call in 'Sharepoint hosted app'.

Hi I am facing the three questions below.
1. How to use default RTE in custom page in Sharepoint hosted app.
I saw the article of Rich text Editor (ribbon based) in a webpart in SharePoint 2013 and tried it. But it did not work well. I guess it needs code-behind setting, however sharepoint hosted app does not support code-behind.
Does anybody know how to do this?
2. In above case, I placed the below code on custom page and tried to get the field's value when submit button was clicked.
<SharePoint:InputFormTextBox ID="rftDefaultValue"
RichText="true"
RichTextMode="FullHtml" runat="server"
TextMode="MultiLine" Rows="5">
</SharePoint:InputFormTextBox>
In debugger, the returned value was 'undefined'.
var note = $('#hogehoge').val();
Is it possible to get the RTE value? If yes, please let me know how to do this.
3. I need to submit the RTE value using REST call.
In this
article in MSDN, the item creation sample treats single line text field. Does anybody know the sample for RTE?

Hi,
According to your description, you might want to use Rich Text Editor control in your SharePoint hosted app.
First of all, I would suggest you post one question in one thread to make it easier to be discussed, which would also help you get a quick solution.
Though we can add this control into a SharePoint hosted app, however, as we can’t add code behind for it, plus with the potential compatibility issues in different
browsers, I would suggest you use other JavaScript Rich Text Editor plugins instead.
Two JavaScript Rich Text Editor plugins for your reference:
http://quilljs.com/
http://nicedit.com/
If you want to submit the value of Rich Text Editor control to a SharePoint list using REST call, since the content in the Multiple Line of Text column is wrapped
with nested HTML tags, the similar requirement would also be applied to the content to be submitted.
Here is a code snippet about how to update a Multiple Line of Text column for your reference:
updateListItem(_spPageContextInfo.webAbsoluteUrl, "List018", 1);
function updateListItem(siteUrl, listName, itemId)
var itemType = GetItemTypeForListName(listName);
var item = {
"__metadata": { "type": itemType },
"MultiTextEnhanced": "<div><a href='http://bing.com/'>Bing</a><br></p></div>",
"Title": "123"
$.ajax({
url: siteUrl + "/_api/web/lists/getbytitle('" + listName + "')/items(" + itemId + ")",
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
success: function (data) {
console.log(data);
$.ajax({
url: data.d.__metadata.uri,
type: "POST",
contentType: "application/json;odata=verbose",
data: JSON.stringify(item),
headers: {
"Accept": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val(),
"X-HTTP-Method": "MERGE",
"If-Match": data.d.__metadata.etag
success: function (data) {
console.log(data);
error: function (data) {
console.log(data);
error: function (data) {
console.log(data);
// Getting the item type for the list
function GetItemTypeForListName(name)
return"SP.Data." + name.charAt(0).toUpperCase() + name.slice(1) + "ListItem";

OnPremise: Sharepoint Hosted App gives 401 unauthorized error while accessing UserProfile Rest Service

Hi All,
I have SharePoint hosted app deployed on On-Premise using(F5) which reads User Profile data consumes WCF(Hosted on same server) through REST API to insert data in to SQL DB(Different server).
SharePoint hosted app was working as expected and suddenly it started asking for credential and not login(any user) to the application landing page.
Checked SharePoint Logs, IIS Logs and Windows log but did not get any clue.
WCF is accessible, User Profile access is also happening but not sure what changes done on server or infra level which causing this issue.
I have an On-Premise Environment for SharePoint 2013. where we have created SharePoint hosted app which calls "http:///_api/SP.UserProfiles.PeopleManager/GetMyProperties" to get current user's data. but this gives me 401 unauthorized error.
Notes:
I had given read permission to user profile and full control to sitecollection in appmanifest. If I run this app on Office 365 developer site it works fine, but on premise environment it give 401 error.
On premise environment when I deploy this app 3 times it prompt for credential and finally gives the following error
Error message after login 3 times:
{"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access
denied. You do not have permission to perform this action or access this resource."}}}

Digital Signature and SharePoint 2013

Dear Expert,
My company has a plan to do digital signature and sharepoint 2013. Now, we focus for internal use that I know use AD CS. and in near future we use for external use. We plan to buy 3rd party certificate.
My question
1. How to implement this solution? Please suggest
2. If I implemented AD CS, can we use public certificate in near future.
3. Can we use public certificate with SharePoint 2013?
Thank you

Hi,
Based on your description, my understanding is that you want to use Digital Signature in SharePoint Server 2013.
You can use digital signatures in forms ,then use these forms in you SharePoint site.
In InfoPath form ,you can change the form to allow signature here: File>Info>Advanced form options >Digital Signatures .You can choose to sign the whole form or a field .

besides, here is a similar post, you can take a look at:

Permissions required to deploy an "SharePoint hosted App" using VS 2013

Hello,
I'm trying to deploy a SharePoint Hosted App to an OnPrem SP2013 server.
When i hit F5 (from VS 2013) i get the below error:
"Error occurred in deployment step 'Uninstall app for SharePoint': The local SharePoint server is not available. Check that the server is running and connected to the SharePoint farm."
I'm added to the Farm Administrators group, site collection admin and to the admin group of the box. But i do not have any db_Owner permissions the the config / content database.
Do I need DB Access to deploy the apps? Please advice.
Thanks,
Keerth

Yes, you need to have db_owner permissions for the account which you are using to deploy the apps.

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.
Regards,
kashif

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.

Caml query for filtering list item not working as expected in Sharepoint hosted app

I am trying to filter list item based on particular value.
var header = "xyz";
camlQueryHeader.set_viewXml = "<view><Query><Where><Eq><FieldRef Name='Position'/>" + "<Value Type='Text'>" + header + "</Value></Eq></Where></Query></view>";
Instead of getting filtered list items, I get all the list items. What am I missing?
Note: I am creating Sharepoint hosted app using CSOM.
regards, Ritesh Anand

Hi,
According to the code provided, I suggest you modify the code like this:
camlQueryHeader.set_viewXml('<view><Query><Where><Eq><FieldRef Name=\'Position\'/>' + '<Value Type=\'Text\'>' + header + '</Value></Eq></Where></Query></view>');
Here is a documentation of how to use the viewXml property of SP.CamlQuery object:

Can't add images to announcements in SharePoint-hosted app in Office 365

I tried something very simple:
Create a new SharePoint-hosted app
Add a new list to the app, based on the Announcements template
Deploy the app to my Dev site on Office 365
When I now add a new item (aka a new announcement) and try to add an image to the Body field, I encounter two errors (depending on whether I try to add an image from my Computer or from SharePoint)
Adding from my computer gives me an unexpected error:
Adding from SharePoint shows me a structure of all the apps in my hostweb, but no way to upload an image either to the hostweb or the appweb:
Is it not possible to add images to a Rich Text field in a list in an app?

Hi Rene,
For inserting any image from you computer to you App web, you need to create a separate picture library in your app web manually i.e. in your SharePoint hosted app add a new list item, under list settings window choose "create a list instance
base on existing list template" and in the drop down select
picture library. Now deploy the app and try again.
Generally when we insert any image from our computer to a SharePoint rich text field, the image gets upload in one of the document libraries, but this option is not available in the newly created app web, as it doesn't contains any separate library..
For you next error, make sure that in the app manifest you are providing
read access on the web, this will resolve you second problem.
Hope it helps you.....

So in the app you are testing, are you using the FQDN or the NetBIOS name? Bad practice but could you test with both (hard code the absolute URL for testing purposes) then retest your app?
If you are making a web part based on the new app model this will be an "app part" and probably have the same issues you are experiencing. If this is for something internal rather than a product you are developing to resell then the script editor /
content editor web part approach could work for you.

SharePoint hosted App that listens and log SharePoint Events

Basically, what I need, is something that can listen to all events fired in SharePoint and write them to a custom list.
I was thinking of making this as a SharePoint hosted app because it has to work on SP Online as well.
The idea is then, to let a provider hosted app read the custom list every x minutes and do it's own logic depending on the events it reads from the custom list.
So the question is, how do I catch all the events fired in SharePoint and should it be a SharePoint hosted app that does it?
Any thoughts on how to solve this?
Thanks.
Thomas Bomann, simplySo

Hi,
According to your description, my understanding is that you want to track all the event fired in SharePoint .
Listen to the events in SharePoint needs Server side code, see the article below:
Programming Event Handling in Windows SharePoint Services
In SharePoint hosted app, it needs to use Client Object Model, so there is no such Client API to meet the requirement.
More information:
JavaScript Client Object Model in SharePoint 2013
