VB.NET - 调用 Kernel32.DLL 的 Wow64DisableWow64FsRedirection

发布于 2024-09-27 19:12:32 字数 788 浏览 1 评论 0原文

查看 Microsoft 的 Wow64DisableWow64FsRedirection 页面，我看到一些 C 代码。如果您想调用此函数并且它是从 VB.net 恢复的，该怎么办？

到目前为止，我已经这样做了：

 <Runtime.InteropServices.DllImport("KERNEL32.DLL",  EntryPoint:="Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection() As Boolean
End Function

并且我对 Revert 兄弟函数也做了同样的事情。

我这样称呼它：

DisableWow64Redirection()

这似乎有效，因为我调用的 shell 命令实际上在 system32 中找到了它的 exe，但我不确定恢复，它是否需要参数？此还原页面似乎需要我从禁用中获取输出并将其插入到恢复调用中。听起来对吗？如何更改 DLLimport 以接受布尔值并在 Kernal32.DLL 函数中实际使用它？

谢谢！

Looking at Microsoft's page on Wow64DisableWow64FsRedirection, I see some C code. What if you want to call this function and it's revert from VB.net?

So far I have done this:

 <Runtime.InteropServices.DllImport("KERNEL32.DLL",  EntryPoint:="Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection() As Boolean
End Function

And I do likewise for the Revert brother function.

I call it like so:

DisableWow64Redirection()

This seems to work, as the shell command I call after actually finds its exe in system32, but I am not sure about the Revert, does it need a parameter? This Revert page seems to want me to take the output from disable and plug it into the revert call. Does that sound right? How do I change my DLLimport to take in a boolean and actually use it in the Kernal32.DLL function?

Thanks!

您可以将函数定义更改为

<DllImport("kernel32.dll", EntryPoint := "Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection(ByRef output As IntPtr) As Boolean

并定义 Revert()，如下所示：

<DllImport("kernel32.dll", EntryPoint := "Wow64RevertWow64FsRedirection")> _
Public Shared Function RevertWow64Redirection(ByRef handle As IntPtr) As Boolean

您可以像这样调用它们：

Dim handle As IntPtr
DisableWow64Redirection(handle)
RevertWow64Redirection(handle)

我不是 VB.NET 人员，所以也许某些语法不正确 - 重要的是您提供了一个引用参数IntPtr 类型，映射到 PVOID 本机类型。您需要保留它，并将相同的值传递给 Revert()。

You could change your function definition to

<DllImport("kernel32.dll", EntryPoint := "Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection(ByRef output As IntPtr) As Boolean

and define Revert() like so:

<DllImport("kernel32.dll", EntryPoint := "Wow64RevertWow64FsRedirection")> _
Public Shared Function RevertWow64Redirection(ByRef handle As IntPtr) As Boolean

You'd invoke these like so:

Dim handle As IntPtr
DisableWow64Redirection(handle)
RevertWow64Redirection(handle)

I'm not a VB.NET guy, so maybe some syntax is incorrect - the important thing is that you provide a reference parameter of IntPtr type, which maps to the PVOID native type. You'll want to hang on to it, and pass the same value to Revert().
