Convert list into data table

   Here is the code to convert list into data table

   public DataTable ConvertToDataTable<T>(IList<T> data)
        {
            PropertyDescriptorCollection properties =
                TypeDescriptor.GetProperties(typeof(T));

            DataTable table = new DataTable();

            foreach (PropertyDescriptor prop in properties)
                table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);

            foreach (T item in data)
            {
                DataRow row = table.NewRow();
                foreach (PropertyDescriptor prop in properties)
                    row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
                table.Rows.Add(row);
            }
            return table;
        }

ConvertToDataTable(NameList);

How to start Exe file using process start c# in IIS

How to start Exe file using process start c# in IIS I have searched a lot and finally I find solution.So I am writing here my be it will helpful to some one.

Problem : I have created a project with process start in c# it's running in local visual studio build,when I hosting it in IIS it's not running but it's starting the processes and nothing is displaying I checked it in task manager.Code sample:

Process process = new Process();

process.StartInfo.FileName = "calc.exe";

process.StartInfo.UseShellExecute = false;

process.Start();

process.WaitForExit();

And I have tried following solutions

IIS7 does not start my Exe file by Process Start

Foo.cmd won't output lines in process

System.Diagnostics.Process.Start not work from an IIS

nothing helped,Finally I Find solution my self.

Solution :

Download Sample

Asp.net with IIS runs as a service application, which means that it runs under another Window Station and Desktop. However, in Windows, the default visible Window Station and Desktop is WinSta0\Default, which is where the Shell(explorer.exe) runs. So the .exe you created is displayed in an invisible desktop.

Actually, Window Station and Desktop is a good sandbox for GUI security, since Windows do not want the normal GUI application to communication other Services applications through Windows Message.

To display the GUI from a non-visible service application, you have to break the security sandbox of WinSta0\Default, which is a little complex.

However, if you want to create a visible process, it is really hard. Normally, the recommended solution is creating a second GUI application like Winform, and the Asp.net and Winform can communicates through .Net Remoting or other Inter process communication technologies. When the Asp.net wanted to create the visible notepad process, it can tell the Winform client through Net Remoting, then Winform will simply Proces.Start notepad.exe on behalf of Asp.net process.

.Net Remoting :

    .Net Remoting is the solution to solve this problem(refer this link .NET Remoting with an easy example ) I am attaching the sample application to run calculator from IIS Server Click To Download

Script Manager in ASP

ScriptManager control registers the script for the Microsoft AJAX Library with the page. This enables client script support features such as partial-page rendering and Web-service calls.

You must use a ScriptManager control on a page to enable the following features of ASP.NET AJAX:

1. Client-script functionality of the Microsoft AJAX Library, and any custom script that you want to send to the browser.

protected void Button1_Click(object sender, EventArgs e)
{
    Page.ClientScript.RegisterStartupScript(
        this.GetType(),"myscript","alert('hello world!');");
}

2. Partial-page rendering, which enables regions on the page to be independently refreshed without a postback. The ASP.NET AJAX UpdatePanel, UpdateProgress, and Timer controls require a ScriptManager control to support partial-page rendering.

3. JavaScript proxy classes for Web services, which enable you to use client script to access Web services by exposing Web services as strongly typed objects.

[WebMethod]
public int Add(int a, int b) { return a + b; }

function CallAdd()
{
    // method will return immediately
    // processing done asynchronously
    WebService.Add(0,6, OnMethodSucceeded, OnMethodFailed);
}

4. JavaScript classes to access ASP.NET authentication and profile application services.

Sys.Services.AuthenticationService.login
Sys.Services.AuthenticationService.logout

<script type="text/javascript">
    function MyMethod(username, password)
    {
        Sys.Services.AuthenticationService.login(username,
            password,false,null,null,null,null,"User Context"); 
    }
</script>

The controls that UpdatePanel and ScriptManager are used for the ASP.NET AJAX Enabled sites.

• We use them, firstly, because in traditional webpages the entire page is loaded after a postback, the HTML sent to the browser is much larger than it needs to be.
• Second, because the entire page is replaced, the browser has to dismiss the old one and then draw the new one. This causes the page to “flicker,” which results in an unattractive user experience. 

The ScriptManager control serves as the bridge between the client page and the server. As it is like a bridge, you've to use this control if any of the other AJAX controls needs to be added. It manages script resources (the JavaScript files used at the client), takes care of partial-page updates as shown earlier, and handles interaction with your web site for things like web services and the ASP.NET application services such as membership, roles, and profile. Whenever one of the controls within the UpdatePanel causes a postback to the server, only the content within that UpdatePanel is refreshed.

If you analyze the data that gets sent from the server to the browser (using a network analysis tool like Fiddler or Wireshark), you would see that only a limited amount of data gets sent to the client.

You usually place the ScriptManager control directly in a content page if you think you need Ajax capabilities on only a handful of pages.

If you’re going to use Ajax functionality in many of your ASPX pages, you can place the ScriptManager in the master page, so it’s available in all pages that are based on this master.

You can only have one ScriptManager per page (i.e. only one bridge, if there happens two bridges then the page request/response may get confused from where to go!? :D), so if you add one to a master page, you can’t add another one to a content page. In order to access a ScriptManager control that is defined in a master page from a content page, you can use the ScriptManagerProxy.
