I am not sure how this should work. When clicking to select a position
where the selected area starts, the window under the mouse pointer
receives the click event, so it's not that easy to provide a selection
mechanism.

make take a snapshot of the whole desktop, then use the mouse to select the
area of your bitmap and dispose of the rest.

Willl this work?

Yes, this will work. You can add a handler to a picturebox's 'MouseUp'
event and get the coordinates there ('e.X', 'e.Y').

here is code:

Protected Sub CaptureScreen()

Dim hSDC, hMDC As Integer
Dim hBMP, hBMPOld As Integer
Dim r As Integer

hSDC = CreateDC("DISPLAY", "", "", "")
hMDC = CreateCompatibleDC(hSDC)

FW = GetDeviceCaps(hSDC, 8)
FH = GetDeviceCaps(hSDC, 10)
hBMP = CreateCompatibleBitmap(hSDC, FW, FH)

hBMPOld = SelectObject(hMDC, hBMP)
r = BitBlt(hMDC, 0, 0, FW, FH, hSDC, 0, 0, 13369376)
hBMP = SelectObject(hMDC, hBMPOld)

r = DeleteDC(hSDC)
r = DeleteDC(hMDC)

oBackground = Image.FromHbitmap(New IntPtr(hBMP))
DeleteObject(hBMP)

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
CaptureScreen()
PictureBox1.Image = oBackground
End Sub
