我正在使用 MS Detours 2.1 库和 VS 2010。我正在尝试绕过 PlaySoundW 函数。
我无法编译该代码,并且出现以下错误:
Error 2 error LNK1120: 1 unresolved externals (...)\detoursLearning.dll detoursLearning
Error 1 error LNK2001: unresolved external symbol __imp__PlaySoundW@12 (...)\detoursLearning\main.obj detoursLearning
我的代码:
#include <Windows.h>
#include <tchar.h>
#include <detours.h>
namespace Hooks
{
BOOL(__stdcall *OrgPlaySoundW)(LPCTSTR pszSound, HMODULE hmod, DWORD fdwSound) = &PlaySoundW;
BOOL HookPlaySoundW(LPCTSTR pszSound, HMODULE hmod, DWORD fdwSound)
{
Beep(1000, 250);
return TRUE;
}
void DetourPlaySoundW(BOOL disable)
{
if(!disable)
{
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)OrgPlaySoundW, HookPlaySoundW);
DetourTransactionCommit();
} else
{
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)OrgPlaySoundW, HookPlaySoundW);
DetourTransactionCommit();
}
}
}
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
switch(fdwReason)
{
case DLL_PROCESS_ATTACH:
Hooks::DetourPlaySoundW(FALSE);
break;
case DLL_PROCESS_DETACH:
Hooks::DetourPlaySoundW(TRUE);
break;
}
return TRUE;
}
还有一件事,你能解释一下吗:
&(PVOID&)OrgPlaySoundW
