qt加载dll

Posted 2021-01-21

qt加载dll时 dll与qt项目编译器必须是同一个。
同时qt用QLibrary方式是动态加载。就是如果你没有用到dll里面的东西它不会直接加载。

    const char* temp = "D:\Users\pautoenr.dll";
    //HINSTANCE hDLL = LoadLibrary(L"D:\Users\myrootkit.dll");
    QLibrary myLib("D:\Users\myrootkit.dll");
    MyPrototype myFunction = (MyPrototype)myLib.resolve("Min");
    if (myFunction)
        int q=myFunction(1,2);
    //if (!myLib)
    //{
    //  QMessageBox::warning(0, "Title", "Error Message");

    //}
