SetPixel() : An Interesting Example

[plenderj]

Enclosed is an example of using SetPixel().
This example, which I like to call 'flies', creates a black picturebox.
Then once you click inside the PictureBox, it will create what looks like lots of flies.
When you move the mouse cursor around they try to get away from the cursor.
I think it looks quite nice :)

If you have any queries or comments, just let me know.

The flies' positions are goverened by this:


For i = 0 To UBound(pixels) - 1
With pixels(i)
''
'' some code
''
If distanceBetweenTwoPoints(pos, .pos) < 25 Then
Do Until (distanceBetweenTwoPoints(pos, .pos) > 35)
With .pos
.x = .x + (2 * Rnd)
.Y = .Y + (2 * Rnd)
End With
Loop
End If
''
'' some code
''
Next

''
'' elsewhere
''
Private Function distanceBetweenTwoPoints(ByRef point1 As pointapi, ByRef point2 As pointapi) As Single
distanceBetweenTwoPoints = (((point2.x - point1.x) ^ 2) + ((point2.Y - point1.Y) ^ 2)) ^ 0.5
End Function
