Read Pixel from Screen ( using VB.NET)

VB.NET Windows Application

If someone clicks on a pixel on a screen how can the pixel color be read e.g. in Mouse down event

Is it possible to access the screen as a bitmap? i.e. copy a specific area of the screen content into a bitmap.

Get the color of a pixel from a picture box image:

Dim bm As Bitmap = Me.PictureBox1.Image
bm.GetPixel(x, y)

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
'get the picture box's bitmap into the "bitmap " variable
Dim bitmap As Bitmap = PictureBox1.Image
'get the color at the X,Y position, using the event (e) object
Dim color As Color = bitmap.GetPixel(e.X, e.Y)
'get the RGB value
Dim ColorValue As Integer = color.ToArgb

'extract the red, and set the form's caption
Me.Text = "Red = " & CStr((ColorValue And &HFF0000) \ &H10000) & _
" Green = " & CStr((ColorValue And &HFF0000) \ &H100) & _
" Blue = " & CStr((ColorValue And &HFF0000) \ &H1)
End Sub
