How to get disk drives info using C#

In this tutorial i am going to show you how to retrieve information about the various disk drives in your sytem.

#So open visual studio 2008 and create a new windows application. (I have named it as HDD)

#Now add a label and a combo box. Change their properties as follows:
For combo box change name to combHDD
Change the name oth the label to SdriveLabel

#You could also add a menu strip and add controls to it as you want. I have added File and Help menu items.

#Now add 14 more labels and change the name properties to the following values:
ModelLabel
SerialLabel
InterfaceLabel
CapacityLabel
PartitionsLabel
SignLabel
FirmLabel
CylinderLabel
SectorsLabel
Blabel
SectLabel
TpcLabel
HeadsLabel
TracksLabel

#Now arrange the label as in the figure

#Now double click on the form and add the followind code to Form1_Load event

ManagementObjectSearcher mosDisks = new ManagementObjectSearcher(“SELECT * FROM Win32_DiskDrive”);
foreach (ManagementObject moDisk in mosDisks.Get())
{
combHDD.Items.Add(moDisk[“Model”].ToString());
}

This searches for win32 disk drives on your system and adds them to the combo box.

#Also add this at the top of your code

using System.Management;

#Now from your form view, double click on combo box and add the following code to combHDD_SelectedIndexChanged event

ManagementObjectSearcher mosDisks = new ManagementObjectSearcher(“SELECT * FROM Win32_DiskDrive WHERE Model = ‘” + combHDD.SelectedItem + “‘”);

foreach (ManagementObject moDisk in mosDisks.Get())
{

TypeLabel.Text = “Type: ” + moDisk[“MediaType”].ToString();

ModelLabel.Text = “Model: ” + moDisk[“Model”].ToString();

InterfaceLabel.Text = “Interface: ” + moDisk[“InterfaceType”].ToString();

CapacityLabel.Text = “Capacity: ” + moDisk[“Size”].ToString() + ” bytes (” + Math.Round(((((double)Convert.ToDouble(moDisk[“Size”]) / 1024) / 1024) / 1024), 2) + ” GB)”;

PartitionsLabel.Text = “Partitions: ” + moDisk[“Partitions”].ToString();

SignLabel.Text = “Signature: ” + moDisk[“Signature”].ToString();

CylinderLabel.Text = “Cylinders: ” + moDisk[“TotalCylinders”].ToString();

SectorsLabel.Text = “Sectors: ” + moDisk[“TotalSectors”].ToString();
HeadsLabel.Text = “Heads: ” + moDisk[“TotalHeads”].ToString();

TracksLabel.Text = “Tracks: ” + moDisk[“TotalTracks”].ToString();

Blabel.Text = “Bytes per Sector: ” + moDisk[“BytesPerSector”].ToString();

SectLabel.Text = “Sectors per Track: ” + moDisk[“SectorsPerTrack”].ToString();

TpcLabel.Text = “Tracks per Cylinder: ” + moDisk[“TracksPerCylinder”].ToString();
}

This selects the drive selected and displays all the properties of it(in 14 labels) using ManagementObjectSearcher class.

#Now press f5 to run your application. Select a drive and you will see something as follows

How to retrieve a websites source code (HTML) using C#

When i asked my friend about what should i write for my first C# tutorial, he told me to start with installation n all. But i didn’t like it as installation tuturial are found everywhere. I was thinking what should i write that is simple but still interesting than those hello world programs. I was looking at my old works(probably 1 to 1.5 years old) when i found out this getHTML app.

So, lets begin(remember this application requires an internet connection)

=>Open Visual Studio 2008, Select File->New->Project. Under visual C# tab select windows forms application and name the project GetHTML as shown in figure.

=>A form designer will open. From the toolbox tab drag and drop a button ,2 textboxes and a label on to the form.

=>Select the button and open it’s properties(by right clicking).In the properties tab change the following properties the given values
Name:GetHTMLButton
Text:Get HTML

=>Now select the label and change the following properties
Name:URLLabel
Text:URL

=>Then select a text box and change it’s properties to
Name:URLTextBox

=>Then select the other text box and change it’s properties to
Name:HTMLTextBox
Multiline:true
Scrollbars:vertical

=>Now arrange them as shown in figure

=> Now in the designer double click on the GetHTMLButton
This will open up the code and will create a GetHTMLButton_Click event handler.
Now go to the top of the code and add these 2 lines:

using System.IO;
using System.Net;

=>Now in the GetHTMLButton_Click method add the following code:

WebRequest req = WebRequest.Create(URLTextBox.Text);
WebResponse resp = req.GetResponse();
StreamReader read = new StreamReader(resp.GetResponseStream(), Encoding.ASCII);
HTMLTextBox.Text = read.ReadToEnd();

Here we are using the System.Net.WebRequest and System.Net.WebResponse classes to send and recieve request from the URL entered by the user. Then we use the Sysyem.IO.StreamReader class object to read the response recieved and display it in HTMLTextBox.

Now run the program or press CTRL+F5

Enter a URL in the URLTextBox and wait for few seconds, the HTMLTextBox will show you the entire HTML content
