Question

am trying to make a worker thread using MFC so here is the codes:

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);
}

but it gives me this error :

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

idk whats wrong it’s supposed to be right!

Answer 1

From the documentation for AfxBeginThread() you need to cast the second argument to LPVOID:

AfxBeginThread(Test, (LPVOID) param);

and set calling convention of Test to __cdecl:

UINT __cdecl Test( LPVOID lParam)
