# Assigning multiple snap to points using New Point

Hi All

I have found the following line of code that allows me to declare allowed locations for picture boxes to snap to, when moved by the user.

Private _allowedLocations As Point() = {New Point(1, 1), New Point(36, 1), New Point(71, 1), New Point(106, 1), New Point(141, 1)}

The problem is that my grid is 15 x 15, which would mean having to set 225 New Point coordinates.

Is there any way to do this using, for example, a for...next loop, or some other way of assigning the x and y coordinates?

Regards

Terry

Hi Terrygordon;

The below code should get you started on what you need to do to create all 225 Point objects dynamically. You will need to adjust xIncrement and yIncrement for the width and height of your PictureBox.
``````Dim x = 1
Dim y = 1
Dim index = 0
Dim xIncrement = 35        ' Number of pixels wide of Picture box
Dim yIncrement = 35        ' Number of pixels High of Picture box
Dim columns = 15           ' Number of Picture box per row
Dim rows = 15              ' Number of rows of Picture boxs
' Array to hold all picture boxes
Dim _allowedLocations(224) As Point

Code to create all 255 Point's for the picture boxes
For i As Integer = 0 To columns - 1
For j As Integer = 0 To rows - 1
_allowedLocations(index) = New Point(x, y)
index += 1
x += xIncrement
Next
x = 1
y += yIncrement
Next
``````

I would use a List(Of Point) instead.

...but why use an Array/List at all if it is a fixed grid?

Just compute the nearest point from the mouse position.

Integer Division ("\" as opposed to "/") might come in handy...
