Summary
Copies an existing file to a new file, notifying the application of its progress through a callback function.

[return: MarshalAs(UnmanagedType.Bool)]
static extern bool CopyFileEx(string lpExistingFileName, string lpNewFileName,
CopyProgressRoutine lpProgressRoutine, IntPtr lpData, ref Int32 pbCancel,
CopyFileFlags dwCopyFlags);
User-Defined Types:
