ASP.NET Discussion Boards

Hello,
I'm pretty new to ASP.NET..

I'm creating Models using EF, and then creating controllers and views automatically, which is great.

What I want to achieve is that, I want unregistered users not to see create new/Delete/update links. Only admins should see those links and do those operations. How can I do that?

Thanks.

What you need is authentication service. To authenticate the users before they can continue to those actions (Create/Delete/Update), and let only Admin users to continue and perform them by visiting those web pages.

You would find yourself at ease at this web page: http://www.asp.net/identity[^] ASP.NET Identity is the service by ASP.NET that can be used to authenticate users.

how can i find iis manager in windows 8 .. i searched for (inetmgr) and in control panel .. and no result ??

Sounds like it's not installed. Try searching for "Turn Windows Features on or off", and look under "Internet Information Services" -> "Web Management Tools" -> "IIS Management Console".

You have to install the remote tools for Windows 8.1 (RSAT TOOLS)
But they only work with Server 2012.

I did mine last year. It was tricky to install. But I was running server cores on Server 2012, so I had to setup permissions using powerscript and cmd line.

They also had rsat tools for Server 2008, but you had to be running Windows 7.

This seems to be for IIS only, and seems universal. I haven't used them.

rsat tools - This I huse currently on Windows 8.1 and Server 2012. quite happy with them.

Hi!
I need to build a notification tool which sends the email right at the moment when a service portal gets new incident. For this I need to pick up email content from service portal, which can be static data as 'label data' or can be input data as 'text entered' or 'option selected' etc.

I'm willing to build this solution in .net C#. Please suggest me a convinient method through which I can get the email content.

Many Thanks in advance!!

Well you should write some code first to grab the data you want.
Then write some code to send the email, passing the data you gathered to the email message body.
And keep refining the code till your satisfied with it.

Speaking for myself, I have no clue what you want to send in your email.

If the data is coming in a table say "Table1", then create a trigger on the table to get the data and create the message and put the data in table "Table2". Build a Windows Service which monitors the "Table2" row with some status (say open). Take data and send the email and update the status of the row (say Close or sent).

Otherwise Please provide some more clarity on your question exactly what do you want to do?

what does this line means or do ??
response.Cookies.Add(myCookie);

See http://msdn.microsoft.com/en-us/library/system.web.httpresponse.cookies%28v=vs.110%29.aspx[^].

Thanks..

It adds a cookie to the user's machine.

Thanks..

help me i connection database but error ..plz help me .thank you
An error occurred while conecting to the database .The database might be unavailable .An exception of type 'Microsoft.Data.ConnectionUI.SqlDatabaseFileUpgradeRequiredException'.The error message is :'This database file is not compatible with the current instance of sql server

I believe you're not reading the exception. That exception is clear if you just break it down and then read it. Let me read it out for you, "Sql Database File Upgrade Required Exception".

Which means that your SQL file was created in a too older version of SQL Server database, you might need to run the application in a compatible version and upgrade it to a later one, or import the data from it using SQL Server Management Studio.

Help with what? You need to explain what you have tried, and where you are stuck. See also http://www.codeproject.com/Messages/1278599/How-to-get-an-answer-to-your-question.aspx[^].

You might be looking for sample quiz application:

To get specific answer, i would suggest to frame your question properly.

Life is a computer program and everyone is the programmer of his own life.

I have this Card Processing WSDL. I made a service reference and a web reference for the WSDL.

Long story short, I've only done WSDL once for FedEx, so this is new to me. The FedEx was cut and dry, just make a WEB Reference, and code to it.

This one, the First Data is much more complex. So I made a SERVICE Reference, and coded to it.
You have to generate a EndPoint Behavior, so you can calculate the HMAC data, and attach it to the SOAP request header. That part was fairly easy. I figured out how to call the service, but then I get this error

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was ''.

OK I get it. With a Service Request, you sort of have to be in the same domain, perhaps a web server that runs IIS as well. Where as a WEB Request, you can go cross domain.

So my question is, is there a way to cheat the credentials, using the SERVICE Reference, and continue using this method, or use the WEB Reference, and create a new method of endpoint behavior.

Trouble with the first, is that I really don't want to hard code credentials.
Trouble with the latter, is that I have no clue on how to add a endpoint behavior to the WEB Reference.
What would you do?

Here's some code for to satisfy curiosity for SERVICE Reference

'Bind the transaction to the HMAC Header Behavior
Dim httpBinding As BasicHttpBinding = New BasicHttpBinding()
httpBinding.Security.Mode = SecurityMode.Transport
httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows
httpBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName
httpBinding.Security.Message.AlgorithmSuite = ServiceModel.Security.SecurityAlgorithmSuite.Basic256

Dim ws = New firstData_v14.ServiceSoapClient(httpBinding, New EndpointAddress(m_endPoint_Url))
ws.ClientCredentials.Windows.ClientCredential = New NetworkCredential("username", "password", "domain")
ws.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation
ws.ChannelFactory.Endpoint.Behaviors.Add(New HMAC_SR_Header_Behavior(m_key, m_keyID, m_endPoint_Uri))

'Transmit the Card Authorization Request
rxn = New firstData_v14.TransactionResult
rxn = ws.SendAndCommit(txn)

WEB Reference

'Bind the transaction to the HMAC Header Behavior
Dim ws = New com.firstdata.globalgatewaye4.V14.Service

'Transmit the Card Authorization Request
rxn = New com.firstdata.globalgatewaye4.V14.TransactionResult
rxn = ws.SendAndCommit(txn)

Looks like the Service Reference allow me to use the EXact_ID and EXact_Password to authenticate to the Cross Domain Service that runs on a Linux Server.
I'm not quite sure how to authenticate to this server, using the code below. I think I just have a few things wrong here.

I'm not sure if the BasicHttpBinding is my authentication method for credentials, or the channel factory.

'Bind the transaction to the HMAC Header Behavior
Dim httpBinding As BasicHttpBinding = New BasicHttpBinding()
httpBinding.Security.Mode = SecurityMode.Transport
httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic
httpBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName
httpBinding.Security.Message.AlgorithmSuite = ServiceModel.Security.SecurityAlgorithmSuite.Basic256

Dim ws = New firstData_v14.ServiceSoapClient(httpBinding, New EndpointAddress(m_endPoint_Url))
ws.ClientCredentials.Windows.ClientCredential = New NetworkCredential(sCA.Exact_ID, sCA.Exact_Password)
ws.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.None

ws.ChannelFactory.Credentials.UserName.UserName = sCA.Exact_ID
ws.ChannelFactory.Credentials.UserName.Password = sCA.Exact_Password
ws.ChannelFactory.Endpoint.Behaviors.Add(New HMAC_SR_Header_Behavior(m_key, m_keyID, m_endPoint_Uri))

'Transmit the Card Authorization Request
rxn = New firstData_v14.TransactionResult
rxn = ws.SendAndCommit(txn)

Hi guys,

I have a project am working on, I have to fill an excel file with data from textboxes, radiobutton lists, etc ..
the excel file must not be opened for the user, it will be used as a database file.
I have 6 columns to fill.
each time the user clicks the button, all data must be added to the first empty row in the excel file.

the problem is, I tried several ideas (connecting database using SQL commands, ODBC, ...) and everytime I encounter a different error, or simply nothing happens .. errors of course are when running the project in the internet browser, so no compilation errors.
the excel file is an EXCEL 2010, the version of VS is 2008.

here's one of the codes I used, for this code I got an error about ISAM driver not found :

Imports System
Imports System.Data
Imports System.Data.OleDb
Imports System.Data.SqlClient
Imports System.Data.Common
Imports System.IO

Protected Sub Button3_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button3.Click
        If IsDate(TextBox3.Text) = False Or TextBox3.Text = "" Or TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox4.Text = "" Or RadioButtonList1.SelectedIndex = -1 Then
            MsgBox("Veuillez vérifier les champs d'écriture.", MsgBoxStyle.OkOnly, "Champs manquants ou invalides")
            Exit Sub
        End If

        Try
            Dim MyConnection As System.Data.OleDb.OleDbConnection
            Dim myCommand As New System.Data.OleDb.OleDbCommand
            Dim sql As String = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0; Data Source=D:\Data\Excel_File.xlsx;Extended Properties=Excel 12.0 Xml;HDR=YES;")
            MyConnection.Open()
            myCommand.Connection = MyConnection
            sql = "INSERT INTO [feuil1$] (Opérateur, Type_Heures, Date, Heures_Entrée, Heures_Sortie, Tâches) VALUES (@Opérateur, @Type_Heures, @Date, @Heures_Entrée, @Heures_Sortie, @Tâches)"
myCommand.Parameters.AddWithValue("@Opérateur", Label4.Text)
    myCommand.Parameters.AddWithValue("@Type_Heures", RadioButtonList1Text)
    myCommand.Parameters.AddWithValue("@Date", TextBox3.Text)
    myCommand.Parameters.AddWithValue("@Heures_Entrée", TextBox1.Text)
    myCommand.Parameters.AddWithValue("@Heures_Sortie", TextBox2.Text)
myCommand.Parameters.AddWithValue("@Tâches", TextBox4.Text)
            myCommand.CommandText = sql
            myCommand.ExecuteNonQuery()
            MyConnection.Close()
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
        MsgBox("Row Added ")

End Sub

it's okay guys, I finally solved the problem using this code

        cn.Open()
        With cm
            .Connection = cn
            .CommandText = "INSERT INTO [feuil1$] ([Operateur], [Type_Heures], [Date], [Heure_Entree], [Heure_Sortie], [Taches])VALUES (op, th, dt, he, hs, tc)"
            cm = New OleDbCommand(.CommandText, cn)
            cm.Parameters.AddWithValue("op", Label4.Text)
            cm.Parameters.AddWithValue("th", RadioButtonList1.Text)
            cm.Parameters.AddWithValue("dt", TextBox3.Text)
            cm.Parameters.AddWithValue("he", TextBox1.Text)
            cm.Parameters.AddWithValue("hs", TextBox2.Text)
            cm.Parameters.AddWithValue("tc", TextBox4.Text)
            cm.ExecuteNonQuery()
            MsgBox("UPDATE SUCCESSFUL")
            cn.Close()
        End With
End Sub

I know that I can retrieve the values in resx files programmaticaly. But, Is there a way to modify the values of existing resx key's? For eg: there is an entry already in the resx file as below:

Key: UsernameReqdValidation
Value: User Name is required.

I want to change this value to 'UserName is mandatory'. Can this can be changed by the user on run time?

I googled for a while, but couldn't find any useful stuff. Please help.

i was reading a signalr private & public chat code and it looks great but few area i just do not understand. i was reading from this url

http://www.tugberkugurlu.com/archive/mapping-asp-net-signalr-connections-to-real-application-users

https://github.com/tugberkugurlu/SignalRSamples/blob/master/ConnectionMappingSample/ConnectionMappingSample/Hubs/ChatHub.cs

public class User {
public string Name { get; set; }
public HashSet<string> ConnectionIds { get; set; }
}

public class ChatHub : Hub {

private static readonly ConcurrentDictionary<string, user=""> Users
= new ConcurrentDictionary<string, user="">(StringComparer.InvariantCultureIgnoreCase);

public override Task OnConnected() {
string userName = Context.User.Identity.Name;
string connectionId = Context.ConnectionId;
var user = Users.GetOrAdd(userName, _ => new User {
Name = userName,
ConnectionIds = new HashSet<string>()
});
lock (user.ConnectionIds) {
user.ConnectionIds.Add(connectionId);
// // broadcast this to all clients other than the caller
// Clients.AllExcept(user.ConnectionIds.ToArray()).userConnected(userName);
// Or you might want to only broadcast this info if this
// is the first connection of the user
if (user.ConnectionIds.Count == 1) {
Clients.Others.userConnected(userName);
}
}
return base.OnConnected();
}
}

i do not understand OnConnected() function very well. so please help me to understand it. why they use

HashSet class ?

if some one see the full code from my given url then please tell me how they could handle users with same name but different connection id?

thanks
