Change Wallpaper (Resolved)

[Mushroom Realm]

I'm using this code to choose a random picture from a folder that I have selected and then change the wallpaper to it. The problem is that the wallpaper doesn't actually change. What have I done wrong?

Public Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long
Sub Main()
Dim pic() As String
Dim file As String
Dim path As String
Dim count As Integer
Dim i As Integer
Randomize Timer
path = "C:\Windows\Desktop\Graphics\Desktops\"
file = Dir(path)
Do While file <> ""
If file <> "." And file <> ".." Then
ReDim Preserve pic(count)
pic(count) = file
count = count + 1
End If
file = Dir
Loop
i = Round(Rnd * count)
SystemParametersInfo 20, 0, path & pic(i), &H1
End Sub
