help!! drag & drop images to a grid

How do I create a grid like the one in edit mode, then be able to drag images that snap. What im trying to create i somewhat like the diablo inventory.

Anyone??

Here's some code that does it (image named Image1). When you release the mouse button the image snaps into place. You can change the grid size by altering the value of the constant.

VB Code:

Private Const GridSize As Single = 1200
 
Private Sub Image1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Static mouseposx As Single, mouseposy As Single
    If Button = 1 Then
        Image1.Left = Image1.Left + X - mouseposx
        Image1.Top = Image1.Top + Y - mouseposy
      Else
        mouseposx = X
        mouseposy = Y
    End If
End Sub
 
Private Sub Image1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = 1 Then
        Image1.Left = Round(Image1.Left / GridSize, 0) * GridSize
        Image1.Top = Round(Image1.Top / GridSize, 0) * GridSize
    End If
End Sub
