I am using MOSS 07 & VisualStudio 07 (c#) on a WindowsServer2003
My Problem is that I want to have access from one Sharepoint to another.
In SharePoint_1 is a SPList I want to read out from SharePoint_2.
The results of my research are IMPERSONATION and RUN_WITH_ELEVATED_PRIVILEGES.
With impersonation I can read out the html code of the SPSite I am connected with, but how can I get the List I want?
When I try to RunWithElevatedPrivileges I have to take a user form the site of SharePoint_1. But I cant get the User (even if I got his name) because of a FileNotFoundException.
How can I solve the problem?
Thanks
There is something I forgot to tell.
In the List are Attachments and I need access to them, too.
What would be the best way to solve this issue?
Hopefully its not very tricky, because I used Sharepoint 5 weeks ago the first time and dont so feel very familiar with it :)
Thanks
You dont need to specify a user when using SPSecurity.RunWithElevatedPrivileges. I think you will be ok if you use:
[url] = url to the other site collection
SPSecurity.RunWithElevatedPrivileges(() => {
using (var site = new SPSite("[url]")) {
using (var web = site.OpenWeb()) {
// Access list here
}
site.RootWeb.Dispose();
}
});

I am using ASP.net C# for a web application that integrates with the Facebook API. My application will allow users to create a group for sharing code. I need to use Facebook API to let the user invite friends from Facebook to join his group on my application. This is a requirement for an assignment so please don't give suggestions to create a group of users that are registered with my site only.
Until now I have the request dialog with all the friends listed (MultiFriendSelector()) with this code:
<p> Click <span id="span-link" onclick="sendRequestViaMultiFriendSelector(); return false;">here</span> to add friends from your Facebook account to your group! </p>
But I am stuck on how to get the id's and details of these invited users so I can save them in my database and allow them to access the group they were invited to. How can I do this please? I can't seem to find anything related to this.
By the way I know that there is a related question which gives this code:
if( Request["ids"] != null )
((Site)Master).FbInviteSent(Request.QueryString.GetValues("ids"));
but I don't know what Master is and I cant get it to work.
Thanks for your help :)
Whenever you call the request dialog, you may pass a callback function:
function sendRequestViaMultiFriendSelector() {
FB.ui({method: 'apprequests',
message: 'My Great Request'
}, requestCallback);
}
The requestCallback will receive the response, and this response returns the facebook id of the users, who were invited
function requestCallback(response){
for (var i = 0; i < response.to.length; i++) {
fb_id = response.to[i];
// Do something with fb_id.
}
}
From looking at the code in the other answer it looks like the facebook API will call back to your page with a query string parameter of ids.
I.e. It will call you site with a url like this.
http://wwww.yoursitesulr.com/mypage.aspx?ids=13,22,44
You can then pull out the id's from the query string using
string myIds = Request.QueryString["ids"];
You can then convert them to a array.
var ids = myIds.Split(',');
If you are using MVC then you can take advantage of the model binders and just put an int array in your view model and it will get bound automatically.
The answer below addresses your specific issie so I would use this as a starting point.

Let me know if you have any questions regarding the above solution.

I am trying to access data remotely from sharepoint 2010 site using client object model. For some restrictions I am not able to use CAML query even if I use I am not able to filter for proper audiences based on user login (if you can help me regarding the CAML query is also fine :: i do not know how to get current user audience name and all audiences using CAML/client object model. This code sits on the mobile site and calling the share point site as shown in my code). This following code works good but not able to get the content from the webpart. Can someone help regarding this.
using (ClientContext ctx = new ClientContext("https://mysite.com/Pages/Default.aspx"))
{
ctx.ExecutingWebRequest += new EventHandler<WebRequestEventArgs> (clientContext_ExecutingWebRequest);
File home=ctx.Web.GetFileByServerRelativeUrl("/Student/Pages/default.aspx");
//get the web part manager
Microsoft.SharePoint.Client.WebParts.LimitedWebPartManager wpm = home.GetLimitedWebPartManager(Microsoft.SharePoint.Client.WebParts.PersonalizationScope.Shared);
IEnumerable<Microsoft.SharePoint.Client.WebParts.WebPartDefinition> wpds = null;
//create the LINQ query to get the web parts from
//the web part definition collection
wpds = ctx.LoadQuery(wpm.WebParts.Include(wp => wp.Id,wp => wp.WebPart));
//load the list of web parts
ctx.ExecuteQuery();
//enumerate the results
foreach (Microsoft.SharePoint.Client.WebParts.WebPartDefinition wpd in wpds)
{
string title= wpd.WebPart.Title;
Microsoft.SharePoint.Client.WebParts.WebPart wpart = wpd.WebPart;
????? How to render and receive the data (looking for the same data When you browse the site with the browser)
}
Code continues...
I am also struggling with this issue. It really looks like this is not possible with client object model. Actually i've asked it to some SharePoint staff member at Build Conference 2012.
But, with the SharePoint Designer it's actually possible to download the wanted WebPart. Fiddler may come handy to track down which service will deliver you the bits.
Take a look at this post here on SharePoint StackExchange
Unfortunately the post will not give you any concrete way to solve it.
Wish you good luck!
Update
Thanks to a comment by #IvanL, it turns out that the problem is Google specific. I have since tried other providers and for those everything works as expected. Google just doesn't seem to send claims information. Haven't yet been able to figure out why or what I need to differently to get Google to send it.
A wild stab in the dark says it may be related to the realm being defaulted to http://:/ as I have seen an answer by Andrew Arnott that Google changes the claimed identifier for the same account based on the realm passed with the authentication request.
Another possibly important tidbit of information: unlike many of the examples that can be found around the web for using dotnetopenauth, I am not using a "simple" textbox and composing the openIdIdentifier myself, but I am using the openID selector and that is providing the openIdIdentifier passed to the ValidateAtOpenIdProvider. (As per the Adding OpenID authentication to your ASP.NET MVC 4 application article.)
Question is: why is IAuthenticationResponse.GetExtension() always returning null when using Google as the openId provider, when otherwise all relevant gotcha's with regard to Google (Email requested as required, AXFetchAsSregTransform, etc) have been addressed?
Original
I am struggling with getting DotNetOpenAuth to parse the response returned from the provider. Followed the instructions of Adding OpenID authentication to your ASP.NET MVC 4 application up to the point where the login should be working and a login result in a return to the home page with the user's name (nick name) displayed at the top right. (That is up to "The user should at this point see the following:" just over half way down the article).
I am using Visual Studio Web Developer 2010 Express with C#. DotNetOpenAuth version is 4.0.3.12153 (according to the packages.config, 4.0.3.12163 according to Windows Explorer).
My web.config was modified following the instructions in Activating AXFetchAsSregTransform which was the solution for DotNetOpenId - Open Id get some data
Unfortunately it wasn't enough to get it working for me.
The openid-selector is working fine and resulting in a correct selection of the openid provider. The authentication request is created as follows:
public IAuthenticationRequest ValidateAtOpenIdProvider(string openIdIdentifier)
{
IAuthenticationRequest openIdRequest = openId.CreateRequest(Identifier.Parse(openIdIdentifier));
var fields = new ClaimsRequest()
{
Email = DemandLevel.Require,
FullName = DemandLevel.Require,
Nickname = DemandLevel.Require
};
openIdRequest.AddExtension(fields);
return openIdRequest;
}
This all works. I can login and authorize the page to receive my information, which then results in a call to GetUser:
public OpenIdUser GetUser()
{
OpenIdUser user = null;
IAuthenticationResponse openIdResponse = openId.GetResponse();
if (openIdResponse.IsSuccessful())
{
user = ResponseIntoUser(openIdResponse);
}
return user;
}
openIdResponse.IsSuccessful is implemented as an extension method (see linked article):
return response != null && response.Status == AuthenticationStatus.Authenticated;
and always is successful as the ResponseIntoUser method is entered:
private OpenIdUser ResponseIntoUser(IAuthenticationResponse response)
{
OpenIdUser user = null;
var claimResponseUntrusted = response.GetUntrustedExtension<ClaimsResponse>();
var claimResponse = response.GetExtension<ClaimsResponse>();
// For this to work with the newer/est version of DotNetOpenAuth, make sure web.config
// file contains required settings. See link for more details.
// http://www.dotnetopenauth.net/developers/help/the-axfetchassregtransform-behavior/
if (claimResponse != null)
{
user = new OpenIdUser(claimResponse, response.ClaimedIdentifier);
}
else if (claimResponseUntrusted != null)
{
user = new OpenIdUser(claimResponseUntrusted, response.ClaimedIdentifier);
}
else
{
user = new OpenIdUser("ikke#gmail.com;ikke van ikkenstein;ikke nick;ikkeclaimedid");
}
return user;
}
My version above only differs from the code in the linked article by my addition of the final else block to ensure that I always get the home page with a user name and a logoff link displayed (which helps when trying to do this several times in succession).
I have tried both Google and Yahoo. Both authenticate fine, both return an identity assertion as logged by the WebDev server. However, GetUntrustedExtenstion and GetExtension always return null. I always get to see "ikke nick" from the last else, never the name I actually used to authenticate.
I am at a loss on how to continue to try and get this to work. It probably is some oversight on my part (I am an experienced developer but just started dipping my toes in C# and web front-end development), and I can't see it.
Any and all suggestions on how to proceed / debug this are very much welcome.
Are you using Google as OpenId provider to test your solution against? Because Google has/had the habit of including the Claims only the first time you authenticate the application. So perhaps try using a fresh google account and see if that works?
Sorry for the slow response, doing a big migration at a client this week :-) Glad that this little comment resolved your issue.
Im using dotCMIS and would like to do a simple connect to my SP2010 server. Im trying to do this with C# like here http://chemistry.apache.org/dotnet/getting-started-with-dotcmis.html in the first part
So I have something like this:
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters[SessionParameter.BindingType] = BindingType.AtomPub;
parameters[SessionParameter.AtomPubUrl] = "http://mysharepoint";
parameters[SessionParameter.User] = "SPAdmin";
parameters[SessionParameter.Password] = "1234sharepoint";
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession(); //exception unathorized
But I get always the exception: DotCMIS.Expcetions.CmisRunterimException: Unathorised
Any ideas? Via browser I can login to the site with the same user/pass, so thats might be not the problem. At first I tought its because of the NTLM problem (https://issues.apache.org/jira/browse/CMIS-531) but even if Im using parameters[SessionParameter.AuthenticationProviderClass] = "DotCMIS.Binding.NtlmAuthenticationProvider"; its the same exception. And well... this exception is not really helping me. I wish I could get more information - maybe there is a better way? What else could I try? Thank you!
PS: And yes, before I started with dotCMIS I did install and configure the MS CMIS connector: http://technet.microsoft.com/en-us/library/ff934619.aspx
Your AtomPubUrl looks suspicious. I can't tell if that's a placeholder you've added to mask the real URL or if that's the actual URL you are using. If it is the actual URL it looks like it is missing the path to the AtomPub service document. To tell if that's the case, you should be able to invoke the URL, log in, and get a bunch of XML back, which is the CMIS service descriptor. If instead you are getting a user-facing page full of HTML, you are using the wrong URL.
For example, in Alfresco, users log in to /share, but the AtomPub binding is at /alfresco/cmisatom.
Yes the AtomPubUrl was wrong.
For sharepoint its not enough to post the default sp url (http://mysharepoint) or the url to the cmis lib (http://mysharepoint/cmis)
I need to point to the repository id, somehow the sp endpoint for CMIS is:
http://mysharepoint/_vti_bin/<myLib4CMIS>/<repID>?getRepositoryInfo
http://technet.microsoft.com/en-us/library/ff934619.aspx
Somehow it was confusing, but its working :) dotCMIS is really nice.
I am new to SharePoint Services and I hit a wall with one of my tasks. I need to retrieve data from a Site Column. How do I get about that? So far I only see APIs that can retrieve lists and not site columns.
Please let me know if any of you know to do this.
Thanks !!
using(SPSite site = new SPSite("http://portal"))
{
using (SPWeb web = site.RootWeb)
{
foreach (SPField field in web.Fields)
{
Console.WriteLine(field.Title);
}
}
}
These will give you all the columns for a web (in this case, the RootWeb). If your site column is related to a list, you need to get directly from the SPListItem property (ex.: item["CustomAssociatedColumn"])
