Address of a variable: Difference between revisions

=={{header|Visual Basic .NET}}==

Visual Basic uses managed memory that can be moved around at any time. If a memory address for a variable is needed, the address is created first and then its contents copied.

===Get the Address===

Allocates a stable address in unmanaged memory, copies a variable to it, then returns the address itself.

Dim x = 5

Dim ptrX As IntPtr

ptrX = Marshal.AllocHGlobal(Marshal.SizeOf(GetType(Integer)))

Marshal.StructureToPtr(5, ptrX, False)

Dim addressX = ptrX.ToInt64

===Set the Address===

Sets the pointer to the address A100 in hex.

Dim ptrX As New IntPtr(&HA100)
