在我看来，这只能通过全局钩子来完成.但是.NET不支持全局钩子，看看这个答案.所以你不能用 VB.NET 但可以用 C++.

In my opinion this can be done only with global hook. But global hook is not supported by .NET, take a look at this answer. So you can't do this with VB.NET but can with C++.

您可以使用 VB.NET 或任何其他 .NET 语言执行此操作，请参阅有关指针的注释.

you can do this with VB.NET or any other .NET language, see comments for pointers.
