LET CREATE OUR OWN SCREENSHOT FOR OUR PC's IN Visual Basic .NET

This tutorial i will show you how to make a screen shot (capture screen) program in vb.net:
Create a new program (I am using Visual Basic 2010 Express Edition for this Tutorial)

Click on Project next to Create: 

Click on Windows Form Application, and name the project "Your name's ScreenShot" and then click Ok

You can change the form text to "your name's screen shot". Click on the form and then go to properties window, then change the text property.
Add three buttons to the form. Change the text of the first button to Shoot. This button will capture the screen. Change the second button to Save, and the third button to Area:

  Change the Anchor property of each button. The shoot button: change it's anchor property to

 Change the Anchor property of the Save button to Top, Left, Right.
 Change the Anchor property of the Area button to Top, Right.
 Add a picture box from the toolbox to the form.

Change the picture box "size image". Click on the small arrow on the top right of the picture box:

Change also the Anchor property of the picture box to Top, Bottom, Left, Right:

We will add one more form to the project. The new form will determine the area of the screen to be captured by the Screen Shot Project.
On the Project menu, click on Add Windows Form:

 Click on Add.
Change some properties of the new form.
Change the text of the form to "Click here and drag".
Remove the Control box from the form. In the properties window, change Control Box property to False.
Change the Opacity of the form to 50%
The Opacity property determines the transparency of the form. In other words, changing the Opacity property to a lower number, let the user see what behind the form.

The form should look like this: 

 Go back to the first form to add some code:
