I am using below code to fetch members of AD group but it is giving me mentioned exception.

PrincipalSearchResult<Principal> resultCollection = groupPrincipal.GetMembers(false);foreach(var userPrincipal in resultCollection)

Foreach loop is failing by giving below exception.

i am getting the following error when i am running my project in.net

Hi,

I am looking for a .NET "scanning API" to scan the documents from .NET application, is there any any good example I can use for this. I want to launch .NET scanning application from another Visual basic application.

Thanks,

Rajeev

Hello,

I want to develop a .Net application to scan some documents using VB.Net or C#.Net.

I searched for any component or any SDK provided by Microsoft which I can use to develop this application but no luck till yet. On Internet I found many third party components/sdk which are claiming to be .Net complaint but I am looking for component/sdk for scanning which is either provided by Microsoft or inbuilt in .Net Framework or VisualStudio.

Hello,

I try to use the code sample from code project inorder to execute scan documents :http://www.codeproject.com/KB/dotnet/twaindotnet.aspx
It works on Windows-XP and not working on Windows-7.

1. Is there is any specification on windows-7 that should be considered ?
2. Why the code is now working on windows-7, Can you supply me sample code that works on windows-7 ?

Thnx,
khalil

Dear sir/miss

I created a shared configuration to set my enterprise library so that I can use it from different types of projects/applications within one Solution in the Visual Studio. I have created my own template but the logs till some issues. In the Result logs sample,

(1) I still get a number of categories which are not stated in my formatter whichI have highlighted in bold.
(2) Also I realised the TimeStamp which I stated in the "Text Formatter" is giving GMT -8 even thought I set as (local) but giving the correct one in "Policy"

Thank you for any help you can provide me with.

I have added the code snippet below:

The perplexing part is, the method the problem seems to originate from is simple:

internal static IDocumentPaginatorSource GetInactiveContent(MemoryStream memStream, string memoryUri)
{

FixedDocumentSequence fixedDocSeq = null;

var packageUri = new Uri(memoryUri);

var package = Package.Open(memStream);

PackageStore.AddPackage(packageUri, package);
XpsDocument newDoc = null;

newDoc = new XpsDocument(package, CompressionOption.Fast, memoryUri);

fixedDocSeq = newDoc.GetFixedDocumentSequence();
DocumentReference docReference = fixedDocSeq.References.First();
FixedDocument doc = docReference.GetDocument(false);
var fixedPage = doc.Pages[0].GetPageRoot(true);
fixedPage.Background = Brushes.Transparent;


return fixedDocSeq;
}

And it looks like the call to 'new XpsDocument' is what's causing it.   I say 'looks like' because removing that call eliminates the exception, but then we don't get the XpsDocument either.  Attempting to try/catch the exception here doesn't work,as it seems to bubble up through .NET and crash our application.

This appears to be some sort of timing issue, as it only happens under certain circumstances, mostly involving cross domain content from the application be closed/opened rapidly.

The URI's we are using are defined as:

_FrameControlUri = string.Format("memorystream://printstream{0}", Guid.NewGuid().ToString("N"));

In an attempt to keep them always unique, so it doesn't seem to be an issue with the URI itself, I'm suspicious that perhaps a package is somehow getting removed from the PackageStore and then the internal code .NET code to create the XPSDocument throws an exception.

The application is very complex, and providing a small sample to reproduce the problem won't be possible.  If you could help me understand that exception message , and possibly point me in the right direction to working around or preventing the problem it would be greatly appreciated.

Thanks,

Chris

hi,

I want code for the all possible combination of array elements(integers) in c#.

for example:

input:1,2,3,4

Output:

12342134231423413241342134124312 ...............................

I've written method that returns collection of UserPrincipals in specified AD group and all groups nested inside it.

The method works really well with most AD groups. Unfortunately if specified group has 'Domain Users' nested inside it, the method doesn't return users from 'Domain Users'. However, if you request users from 'Domain Users' directly, it works. If you nest inside searched group any other user-created group, it works as intended.

To put it simply, GroupPrincipal.GetMembers(true) doesn't seem to return users from built-in groups that are nested inside searched group. This is not pointed out in this method's documentation. Maybe I'm doing something wrong.

public static List<UserPrincipalEx> GetUsersInGroup(IdentityType identityType, String groupIdentifier)
{
    List<UserPrincipalEx> userPrincipalExList = new List<UserPrincipalEx>();
    List<UserPrincipal> userPrincipalList = new List<UserPrincipal>();
    GroupPrincipal gp = GroupPrincipal.FindByIdentity(domainContext, identityType, groupIdentifier);
    if (gp == null)
    {
        return userPrincipalExList;
    }

    IEnumerable<Principal> psr = gp.GetMembers(true).Where(o => o.StructuralObjectClass == "user");
    foreach (var item in psr)
    {
        userPrincipalExList.Add(UserPrincipalEx.FindByIdentity(domainContext, item.Sid.ToString()));
    }

    return userPrincipalExList;
}

Does anybody know solution to this problem?

I'm having the same problem as in this post:

https://social.msdn.microsoft.com/Forums/vstudio/en-US/77dc733e-a13d-4349-9088-8065b85d5c3f/userprincipalchangepassword-stops-working-after-windows-updates-3177108-and-3167679?forum=netfxbcl

but the accepted solution is not working for me. 

The gist is using user.ChangePassword in the using System.DirectoryServices.AccountManagement namespace. 

I'm sure it must be related to the updates referred to in the other article, but apparently, it is possible to fix. 

I have verified the upn of my principal user, but still no luck. 

My code: 

using (var context = GetPrincipalContext())
{
  string sUserName = GetUserName();
  string oldPassword = GetPassword();
  string newPassword = GetNewPassword();
  using (var user = UserPrincipal.FindByIdentity(context, IdentityType.UserPrincipalName, sUserName))
  {
    try
      {
        user.ChangePassword(oldPassword, newPassword);
        Console.WriteLine("Password Changed");
      }
      catch (Exception e)
      {
        Console.WriteLine("Change password failed:        {0}", e.Message);
      }
    }
  }
}

//My GetPrincipalContext Method returns oPrincipalContext:

oPrincipalContext = new PrincipalContext(
          ContextType.Domain,
          (ADLocations[ADLocation]).Domain,
          (ADLocations[ADLocation]).OU,
          ContextOptions.Negotiate,
          (ADLocations[ADLocation]).ServiceUser,
          (ADLocations[ADLocation]).ServicePassword);

Does anyone have an suggestions? 

How to resolve the error and other strange errors happening after converting web application from framework 3.5 to framework 4.5 using visual studio 2012?

I am currently working on a new project wherein the client wishes to run the application in IE11. From what information I have gathered so far, its made using the WebPart Framework.

As of now the debugger is not throwing any errors but I see none of the buttons such as delete control, copy control etc are working. I have modified some methods so now the drag drop javascript file works by which we drag and drop the user controls on the sections which is managed by WebPart.

I have tried to debug alot and i am new to .NET so I was wondering is this WebPart framework  the culprit behind these issues ? Does it have compatibility issues? It works fine till IE8, but  in IE11 the application just does not work. What can be a way forward ? Will WebPart not work anymore and is upgrading the .NET framework from 2.0 to 4.5 the only solution left ?

Thanks ,

No sure if this is the correct forum to post this question

I have multiple types that are derived from the same interface. And I am using Unity IOC container to register the types

public interface IService
{
}

public class ServiceA : IService
{
}

public class ServiceB : IService
{
}

public class ServiceC : IService
{
}

If I register these types as below with Unity IOC container

       container.RegisterType<IService, ServiceA>("NameA");
       container.RegisterType<IService, ServiceB>("NameB");
       container.RegisterType<IService, ServiceC>("NameC");

then I can resolve types as below without any issue.

var service = container.Resolve<IService>("NameA");

However I am getting list of types that needs to be register with container from outside. (lets assume from text file). So I need to register only those types that are in the provided list.

public class Program
{
    public static void Main()
    {
        // i will be getting this  dictionary values from somewhere outside of application
        // but for testing im putting it here
        var list = new Dictionary<string, string>();
        list.Add("NameA", "ServiceA");
        list.Add("NameB", "ServiceB");
        list.Add("NameC", "ServiceC");


        var container = new UnityContainer();
        var thisAssemebly = Assembly.GetExecutingAssembly();

        //register types only that are in the dictionary
        foreach (var item in list)
        {
            var t = thisAssemebly.ExportedTypes.First(x => x.Name == item.Value);
            container.RegisterType(t, item.Key);
        }

        // try to resolve. I get error here
        var service = container.Resolve<IService>("NameA");
    }
}

but I am getting exception

An unhandled exception of type 'Microsoft.Practices.Unity.ResolutionFailedException' occurred in Microsoft.Practices.Unity.dll

Additional information: Resolution of the dependency failed, type = "ConsoleApplication1.IService", name = "NameA".

Exception occurred while: while resolving.

Exception is: InvalidOperationException - The current type, ConsoleApplication1.IService, is an interface and cannot be constructed. Are you missing a type mapping?


At the time of the exception, the container was:

Resolving ConsoleApplication1.IService,NameA

Please not that for some valid reasons i do not want to use Unity's register by convention option, or Unity's configuration file option to register types. I would like to register them based on the list I have.

I ran the entity framework and it created a couple of classes (actually several classes) like this:

namespace EFTest
{
    using System;
    using System.Collections.Generic;

    public partial class SalesRepresentative
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string CellPhone { get; set; }
    }
}

public partial class SalesEntities : DbContext
{
    public SalesEntities()
            : base("name=SalesEntities")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }

    public DbSet<SalesRepresentative> SalesRepresentatives { get; set; }
    public DbSet<Sales_Regions> Sales_Regions { get; set; }
    public DbSet<SalesRegion> SalesRegions { get; set; }
    public DbSet<State> States { get; set; }
    public DbSet<Territory_Descriptions> Territory_Descriptions { get; set; }
 }

And I found an example of using them like this:

SalesRepresentative sr;
using (var ef = new SalesEntities())
{
    sr = new SalesRepresentative() { ID = IDin };
    ef.SalesRepresentatives.Add(sr);
    ef.SaveChanges();
}

But the tutorial did not mention anything about loading a record.  I looked all over the place here https://msdn.microsoft.com/en-us/data/ee712907 but could not find anything.  Can someone point me to a tutorial that explains how to read rows or give me a code snippet?

Thanks
