Using Marshal to create an unmanaged UInt32 array

[Gareth]

If I want to move a signed integer array to unmanaged memory I can use
the following code:

Dim myArray() As Integer
Dim myPtr As IntPtr

myPtr = Marshal.AllocHG lobal(Marshal.S izeOf(GetType(I nteger)) *
myArray.Length)
Marshal.Copy(my Array, 0, myPtr, myArray.Length)

However I cannot use Marshal.Copy for an array of UInt32

How can I achieve this? (OpenGL doesnae like signed buffer
indices ;) )

Many thanks,
