How to find all comments on a particular linkedin article given articleId?

I published a LinkedIn article and I'm trying to retrieve the comments for this particular article. I obtained the articleId by right clicking on the comments button and copying the link address. I get aritcleId = 7434836657526032700. Should I use GET http://api.linkedin.com/v1/posts/{post-id}/comments where {post-id} is same as articleId?
Below is my code after successful AuthorizationLinkGet call.
string oauth_token = Request.QueryString["oauth_token"];
string oauth_verifier = Request.QueryString["oauth_verifier"];
if (oauth_token != null && oauth_verifier != null)
{
Application["oauth_token"] = oauth_token;
Application["oauth_verifier"] = oauth_verifier;
//get access token
_oauth.Token = oauth_token;
_oauth.TokenSecret = Application["reuqestTokenSecret"].ToString();
_oauth.Verifier = oauth_verifier;
_oauth.AccessTokenGet(oauth_token);
sLinkedInCommentsURL = "http://api.linkedin.com/v1/posts/7434836657526032700/comments";
string response = _oauth.APIWebRequest("GET", sLinkedInCommentsURL, null);
lblMessage.Text = response;
}
I receive following error:

Article ID is not the same field as post id, so that is why you are getting the error you see. The API does not allow you to get comments from publications.

Published my ASP.Net 2013 Website to IIS 7 and receiving an error of Invalid attemp to read data when no data is present

I cannot seem to find out why my SQL data connections are not being recognized and the SQL Data Reader is not being able to read data when I publish my ASP.Net Site. It works when I just use the localhost and it is not published but once I publish it to IIS 7 it can no longer read data from SQL server. Please anyone if you can help that would great. I am very new to IIS 7 and cannot figure this out for the life of me. I have tried to check other blogs but I am coming up with nothing. The error that I am getting is:

Problems in aspnet membership provider

I am using asp.net memebership
I log out the applcation by writting this code for log out
if (Membership.GetUser(HttpContext.Current.User.Identity).IsOnline) ;
{
FormsAuthentication.SignOut();
Response.Redirect(FormsAuthentication.LoginUrl);
}
Response.Redirect("loginpage.aspx");
After then I started the application and gettig the error in code block of authetication .below I am writtng a code and error message
else if (User.Identity.IsAuthenticated == true && Membership.GetUser( Membership.FindUsersByName(User.Identity.Name)).IsOnline==true)
{
FormsAuthentication.SignOut();
FormsAuthentication.RedirectToLoginPage();
MembershipUser currUser = null;
string gt = null;
if (HttpContext.Current.User != null)
{
currUser = Membership.GetUser(true);
gt = currUser.Email;
}
/// string temp = User.Identity.GetProfile().ID;
//string query = "Insert into user_tbl(MemberID)(" + temp + ")";
//Response.Redirect("UserPanel.aspx");
//return;
}
here Membership.FindUsersByName(User.Identity.Name)).IsOnline==true) I am getting this error

Or you could also use Request.IsAuthenticated which dosent get the whole user object and just checks authentication.

According to Visual Studio, Membership.FindUsersByName returns MembershipUserCollection. You pass that object to the Membership.GetUser method, which does accept a parameter of the object type, but that object is supposed to be a user's ID (a GUID in ASP.NET). So, the exception is quite expected: you're trying to pass a collection of users, while the method expects a single user ID.
If you need to check whether a user is currently logged in, you can simply do this:
if (Membership.GetUser() != null)
See this MSDN Library article for more information on the method.

DirectoryEntry.Children.Remove throws "unspecified error"

I have a little code to delete a security group from Active Directory, but when run, I get a COMException with the message "Unspecified error".
Here is the code:
public void DeleteGroup(Model.Asset pADSecurityGroup)
{
using(DirectoryEntry ou = new DirectoryEntry(pADSecurityGroup.Organization.ActiveDirectoryMappings.Single().Identifier))
using(DirectoryEntry group = new DirectoryEntry("LDAP://" + pADSecurityGroup.ActiveDirectoryMappings.Single().Identifier))
{
ou.Children.Remove(group);
group.CommitChanges();
}
}

Custom event details:

Based on the questions/answer in the comments section I revise my answer.
I think you simply forgot the LDAP protocol identifier for the LDAP path of your organization unit. I think, unspecified error means invalid LDAP path.
Try the following code:
public void DeleteGroup(Model.Asset pAsset)
{
using(DirectoryEntry ou = new DirectoryEntry("LDAP://" + pResourcePool.Organization.ActiveDirectoryMappings.Single().Identifier))
{
using(DirectoryEntry group = new DirectoryEntry("LDAP://" + pResourcePool.ActiveDirectoryMappings.Single().Identifier), username, userpwd)
{
ou.Children.Remove(group);
group.CommitChanges();
}
}
}
By the same token, ensure that the LDAP protocol identifier is written using capital letters.
Hope, this helps.

Just guessing: Maybe the DirectoryEntry "ou" is not empty.
MSDN says:
If the entry to be removed is a container, the container must be empty. To delete a container and all its children, use the DeleteTree method.
You also may try to catch the ComException and gather more information so the problem can be analysed.

How can i get a list of the websites in IIS from within a ASPX page using c#?

I'm trying to use
DirectoryEntry root = new DirectoryEntry("IIS://localhost/W3SVC/1/Root");
foreach (DirectoryEntry de in root.Children)
{
}
but I keep getting

In Windows 7/8 go Control Panel / Program And Features / Turn Windows features on or off, and check all items from: Web Managment Tools, (it's include: IIS Managment Service, II 6 Managment Compatibility).
And you can use the code:
public static void OpenWebsite(string name)
{
DirectoryEntry Services = new DirectoryEntry("IIS://localhost/W3SVC");
IEnumerator ie = Services.Children.GetEnumerator();
DirectoryEntry Server = null;
string nombre = "";
while (ie.MoveNext())
{
Server = (DirectoryEntry)ie.Current;
if (Server.SchemaClassName == IIsWebServer)
{
nombre = Server.Properties["ServerComment"][0].ToString();
if (nombre == name)
{
break;
}
}
}
Console.Write(nombre);
}

I'm not too sure what the error is but at a guess it might be installation issue or permissions.
For installation type issues:
http://blogs.msdn.com/b/jpsanders/archive/2009/05/13/iis-7-adsi-error-system-runtime-interopservices-comexception-0x80005000-unknown-error-0x80005000.aspx
For permissions type issues adding something to config like:
<identity impersonate="true" userName="AdminUserName" password="password" />
Or changing the user context that the application pool runs under to one that has local admin rights could work.
Also, the children of IIS://localhost/W3SVC/1/Root will be Virtual Directories or Folders. Websites would be IIS://localhost/W3SVC.
