VB编程：利用地址偏移访问内存

1、运行效果

2、程序代码;

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)

Private Sub Form_Load()
    Dim i As Long
    Dim j As Long
    i = 1234
    j = 4321
    CopyMemory ByVal VarPtr(i), ByVal VarPtr(i) - 4, 4
    Text1.Text = i
End Sub
