Something to bear in mind is that `System.Environment.MachineName;` and `System.Windows.Forms.SystemInformation.ComputerName;` will give you the NETBIOS name of the machine (restricted to 15 characters). 

If you want the full TCP/IP based host name you can  use [`Dns.GetHostName()`][1]:

    string hostName = System.Net.Dns.GetHostName();

Or you can use:

    System.Environment.GetEnvironmentVariable(&quot;COMPUTERNAME&quot;);

Which will return the full computer name set during installation.

Unless I am mistaken on what you want to do..

    System.Environment.MachineName

To get fully qualified name, use:

     System.Net.Dns.GetHostEntry(&quot;&quot;).HostName

The My namespace contains many great &quot;helper&quot; functions like: 

    My.Computer.Name

    System.Windows.Forms.SystemInformation.ComputerName;

Are CPU registers and CPU cache different?

Lately at work, I&#39;ve been doing some translation from Makefiles to an alternative build system. I&#39;ve seen some pretty hairy Make code in some places using functional map, filter, and foreach constructs. This surprised me since I think build scripts ought to be as declarative as possible.

Anyway, this got me thinking: is the Makefile language (say the latest GNU make to be specific) Turing complete?

I want to convert a string to a generic type like `int` or `date` or `long` based on the generic return type.

Basically a function like `Parse&lt;T&gt;(String)` that returns an item of type `T`.  

For example if a int was passed the function should do `int.parse` internally.

Is there any generic Parse() function that will convert a string to any type using parse?

I&#39;m experimenting with this code-first approach, but I&#39;m find out now that a property of type System.Decimal gets mapped to a sql column of type decimal(18, 0).

I was browsing a coworkers c# code today and found the following:

        using (MemoryStream data1 = new MemoryStream())
        using (MemoryStream data2 = new MemoryStream())
        {
            // Lots of code..........
         }

I had always seen the `using` statement followed by a pair of curly braces that defined the scope of the object life. My coworker who wrote the code said that the curly braces for the `data1` `using` statement weren&#39;t needed and the code did the same thing as if they were present and nested the `data2` `using` statement. So, what happens when the curly braces are ommitted?


Can the C# using statement be written without the curly braces?

I am using the `WebClient` class to post some data to a web form. I would like to get the response status code of the form submission. So far I&#39;ve found out how to get the status code if there is a exception

    Catch wex As WebException
            If TypeOf wex.Response Is HttpWebResponse Then
              msgbox(DirectCast(wex.Response, HttpWebResponse).StatusCode)
                End If
           
However if the form is submitted successfully and no exception is thrown then I won&#39;t know the status code(200,301,302,...)

Is there some way to get the status code when there is no exceptions thrown?

PS: I prefer not to use httpwebrequest/httpwebresponse

Very easy today, I think.  In C#, its:

    Dictionary&lt;String, String&gt; dict = new Dictionary&lt;string, string&gt;() { { &quot;&quot;, &quot;&quot; } };

But in vb, the following doesn&#39;t work.

    Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) ((&quot;&quot;,&quot;&quot;))

I&#39;m pretty sure there&#39;s a way to add them at declaration, but I&#39;m not sure how.  And yes, I want to add them at declaration, not any other time.  :)  So hopefully it&#39;s possible.  Thanks everyone.

I&#39;ve also tried:

    Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) ({&quot;&quot;,&quot;&quot;})

And...

    Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {(&quot;&quot;,&quot;&quot;)}

And...

    Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {{&quot;&quot;,&quot;&quot;}}

I&#39;m having a problem with my code:

    Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
        list.Items.Clear()

        cmd.CommandText = &quot;SELECT * FROM borrow where (Department LIKE &#39;%&quot; &amp; TextBox2.Text &amp; &quot;%&#39;)&quot;
        cmd.Connection = con
        cmd.CommandType = CommandType.Text
        con.Open()


        rd = cmd.ExecuteReader()
        If rd.HasRows = True Then
            While rd.Read()

                Dim listview As New ListViewItem

                listview.Text = rd(&quot;ID&quot;).ToString
                listview.SubItems.Add(rd(&quot;Department&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Purpose&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Items_Details&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Requested_by&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Approved_by&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Date&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Status&quot;).ToString)
                listview.SubItems.Add(rd(&quot;Date_Returned&quot;).ToString)

                list.Items.Add(listview)

            End While
        End If
        con.Close()


Once I typed in the string in the textbox to search for an item I get this error: 

&gt; The parameterized query &#39;(@Parameter1 nvarchar(4000))SELECT * FROM

I am curious about the string and primitive types. Article like [this][1] says string is primitive type. However [second article][2] on MSDN does not list string as primitive type. 

However when I ran the code provided in second article, it displays **String is not Primitive type**.

Can any one guide me on this?

Does the task parallel library have anything that would be considered a replacement or improvement over the BackgroundWorker class? 

I have a WinForms application with a wizard-style UI, and it does some long-running tasks. I want to be able to have a responsive UI with the standard progress bar and ability to cancel the operation. I&#39;ve done this before with BackgroundWorker, but I&#39;m wondering if there are some TPL patterns that can be used instead?

When I try to build my solution, I get the following error:

&gt;Visual Studio cannot start debugging because the debug target &#39;c:\target&#39; is missing. Please &gt;build the project and retry, or set the OutputPath and AssemblyName properties appropriately &gt;to point at the correct location for the target assembly.  

My output path is set correctly to **bin\Debug**, but the exe is never created in that folder.  Instead, all I get are the `exe.config`, `vshost.exe`, and `vshost.exe.config` files.

Any idea what&#39;s going on?
