通过提供DLLName查找DLL路径 [英] Locate DLL path by giving a DLLName

问题描述

如果我愿意

  LoadLibrary（ MyTest.dll）
  

Windows将从 C：\TestFolder\Test\MyTest.dll定位并加载它。，因为 C：\TestFolder\Test\ 在％PATH％文件夹中。 / p>

如何模拟相同的功能？我需要找到 C：\TestFolder\Test\MyTest.dll （ C：\TestFolder\Test\ MyTest.dll 作为函数的参数传递给％PATH％中的c $ c>。有没有这样的API？或功能？

P.S。我无法先执行LoadLibrary，然后再执行GetModuleHandle并找到Path，有时此DLL可能是恶意DLL，因此无法加载。因此，我需要找到PATH而不必加载它。

解决方案

要在不运行任何恶意代码的情况下加载DLL，请使用 LoadLibraryEx 和 DONT_RESOLVE_DLL_REFERENCES 和 LOAD_LIBRARY_AS_DATAFILE 标志。

然后您可以使用 GetModuleFileName 。

您还应该阅读有关所有其他标志，使您可以执行Windows能够执行的所有各种搜索。

If I do

LoadLibrary("MyTest.dll")

Windows will locate and load it from "C:\TestFolder\Test\MyTest.dll", because "C:\TestFolder\Test\" is in %PATH% folder.

How can I emulate same function? I need to locate C:\TestFolder\Test\MyTest.dll (C:\TestFolder\Test\ is in %PATH%) by passing MyTest.dll as an argument to a function. Is there such an API? or a function?

P.S. I can't do LoadLibrary and then GetModuleHandle and finding Path, sometimes this DLL could be malicious DLL and I can't load it. So I need to find PATH without having to load it.

解决方案

To load the DLL without running any malicious code inside, use LoadLibraryEx with the DONT_RESOLVE_DLL_REFERENCES and LOAD_LIBRARY_AS_DATAFILE flags.

Then you can use GetModuleFileName.

You should also read about all the other flags, which allow you to perform all the various searches Windows is capable of.
