garbage collector VB.NET

How can i avoid garbage collector releasing the delegate function's address. By default, the GC is on. I've no control over GC. When i pass the AddressOf callback funciton to an unmanaged DLL, the address is lost as soon as the function passing the address of the callback returns. each time the address is a new and when there is a mis-match between the calling address and the actual address, the applicaition faults.

regards

You have to use GCHandle methods to do this. Typically, you create a handle to the managed object using GCHandle.Alloc(), and pass this handle to the unmanaged DLL.

Here is an example from MSDN:
