如何添加系统“windows挂钩”,以便在创建/激活windows时收到通知?

尝试使用开放库 http://mwinapi.sourceforge.net/ 第一尽管它可以很好地作为一个OO层来枚举窗口和其他东西。它做不好

Dino E.'s post on Windows Hooks in the .Net framework

我的目的是让这个应用程序运行,并让它能够在运行时记录所有创建的窗口 . 召唤所有的眼球。。。

can't write global windows hooks in .Net

于是我切换到C++。尽管如此,所有WinAPI调用都返回有效句柄,但我没有看到我的筛选函数被调用——似乎没有收到任何通知。还是不行。。。有人能发现错误吗。

void CWinHookFacade::Hook()
{
    HMODULE hCurrentDll = LoadLibrary(_T("[Path to my hook dll]"));
    m_HookHandle = SetWindowsHookEx(WH_CBT, 
        FilterFunctionForHook, 
        hCurrentDll, 
        0);
    if (m_HookHandle == NULL)
    {
        throw new std::exception("Unable to hook");
    }

}
void CWinHookFacade::Unhook()
{
    if (!UnhookWindowsHookEx(m_HookHandle))
    {
        throw new std::exception("Unhook failed!");
    }
    m_HookHandle = NULL;
}

LRESULT CWinHookFacade::FilterFunctionForHook(int code, WPARAM wParam, LPARAM lParam)
{
    if (code >= 0)
    {
        switch(code)
        {
        case HCBT_CREATEWND:
            wprintf(_T("Created Window"));
            break;
        case HCBT_ACTIVATE:
            wprintf(_T("Activated Window"));
            break;
        case HCBT_DESTROYWND:
            wprintf(_T("Destroy Window"));
            break;
        }
    }

    return CallNextHookEx(m_HookHandle, code, wParam, lParam);
}

Client exe像这样调用Hook\u DLL

int _tmain(int argc, _TCHAR* argv[])
{
    CWinHookFacade::Hook();
    getchar();
    CWinHookFacade::Unhook();
}
