我试图钩CopyItems功能,其工作正常,但当我试图调用它越来越崩溃的回调函数实CopyItems功能,我的代码如下,请帮助我。
PVOID GetInterfaceMethod(PVOID intf, DWORD methodIndex)
{
return *(PVOID*)(*(DWORD*)intf + methodIndex * 4);
}
typedef HRESULT (WINAPI *CopyItemsNext)(IUnknown *punkItems,IShellItem *psiDestinationFolder);
CopyItemsNext Real_CopyItems = NULL;
CopyItemsNext Actual_CopyItems;
HRESULT WINAPI CopyItemsCallback(IUnknown *punkItems,IShellItem *psiDestinationFolder)
{
MessageBoxW(NULL,L"CopyItems Function Called", L"HookedCopyItemS", MB_OK);
return Real_CopyItems(punkItems, psiDestinationFolder);
}
HRESULT WINAPI CoCreateInstanceCallback(REFCLSID rclsid, LPUNKNOWN pUnkOuter, DWORD dwClsContext, REFIID riid, LPVOID *ppv)
{
const char *IFileOperation_GUID = "{3AD05575-8857-4850-9277-11B85BDB8E09}";
char GUIDString[64];
HRESULT HR = Real_CoCreateInstance(rclsid, pUnkOuter, dwClsContext, riid, ppv);
sprintf_s(GUIDString,64, "{%08X-%04X-%04X-%02X%02X-%02X%02X%02X%02X%02X%02X}\0",
rclsid.Data1, rclsid.Data2, rclsid.Data3,
rclsid.Data4[0], rclsid.Data4[1],
rclsid.Data4[2], rclsid.Data4[3],
rclsid.Data4[4], rclsid.Data4[5],
rclsid.Data4[6], rclsid.Data4[7]);
if(strcmp(GUIDString, IFileOperation_GUID) == 0)
{
MessageBoxA(NULL, "IFileOperation_GUID Found", GUIDString, MB_OK);
if(Real_CopyItems == NULL)
{
Actual_CopyItems = (CopyItemsNext)GetInterfaceMethod(*ppv, 17);
MessageBoxA(NULL,"AFTER GetInterfaceMethod", "TEST", MB_OK);
if (MH_CreateHook(Actual_CopyItems, &CopyItemsCallback, reinterpret_cast<void**>(&Real_CopyItems)) != MH_OK)
{
MessageBoxW(NULL, L"Failed CreateHook Real_CopyItem", L"Info!", MB_ICONWARNING|MB_OK);
}
if (MH_EnableHook(Actual_CopyItems) != MH_OK)
{
MessageBoxW(NULL, L"Failed EnableHook Real_CopyItem", L"Info!", MB_ICONWARNING|MB_OK);
}
}
}
return HR;
}
//DllMain Function
BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
if (MH_Initialize() != MH_OK)
{
MessageBoxW(NULL, L"Failed Initialize", L"Info!", MB_ICONWARNING|MB_OK);
}
if (MH_CreateHook(&CoCreateInstance, &CoCreateInstanceCallback, reinterpret_cast<void**>(&Real_CoCreateInstance)) != MH_OK)
{
MessageBoxW(NULL,L"Failed MH_CreateHook CoCreateInstance",L"Info!",MB_ICONWARNING|MB_OK);
}
if (MH_EnableHook(&CoCreateInstance) != MH_OK)
{
MessageBoxW(NULL,L"Failed MH_EnableHook StartDocA",L"Info!",MB_ICONWARNING|MB_OK);
}
break;
case DLL_PROCESS_DETACH:
if (MH_Uninitialize() != MH_OK)
{
}
if (MH_DisableHook(Actual_CopyItems) != MH_OK)
{
}
if (MH_DisableHook(&CoCreateInstance) != MH_OK)
{
}
break;
}
return TRUE;
}
在CopyItemsCallback函数内部上面的代码我正在显示的消息框只是为了确认天气的功能越来越钩R值不要,让我得到了我打电话房地产CopyItems功能后,该消息框,但有它越来越崩溃,请检查什么这个问题与我的代码。
