Question

我正在尝试使用MFC创建一个工作线程，所以这里是代码：

struct ThreadParam
{
    HWND mDlg;    // Note: A handle.
};

UINT TestMFCThread::Test( LPVOID pParam ){
  //do work!
}
void TestMFCThread::OnBnClickedButton2()
{
    ThreadParam* param = new ThreadParam;
    param->mDlg = m_hWnd;
    AfxBeginThread(Test, param);
}

但它给了我这个错误：

1   IntelliSense: no instance of overloaded function "AfxBeginThread" matches the argument list
    argument types are: (UINT (LPVOID pParam), ThreadParam *)

idk什么错了它应该是对的！

Answer 1

从AfxBeginThread()的文档中，您需要将第二个参数强制转换为LPVOID：

AfxBeginThread(Test, (LPVOID) param);

并将Test的调用约定设置为__cdecl：

UINT __cdecl Test( LPVOID lParam)

没有重载函数的实例“AfxBeginThread”匹配参数列表
