Recently in a multithreaded, follow the example of made several multithreading, before doing this is no problem, to this case suddenly appeared this problem, program, are said to search on the net have to use a static member function, I just in front of the function to add a static, is still the same problem, solving

AfxBeginThread (WriteW, (LPVOID) & amp; M_ctrlW, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED);

Thanks, upstairs, I just try, still the same error message pop up

Remove the static, then function definition as the requirements of the thread

CodePudding user response:

Look at the function definition:
CWinThread * AFXAPI AfxBeginThread (AFX_THREADPROC pfnThreadProc, LPVOID pParam,
Int nPriority=THREAD_PRIORITY_NORMAL, UINT nStackSize=0,
DWORD dwCreateFlags=0, LPSECURITY_ATTRIBUTES lpSecurityAttrs=NULL);
CWinThread * AFXAPI AfxBeginThread (CRuntimeClass * pThreadClass,
Int nPriority=THREAD_PRIORITY_NORMAL, UINT nStackSize=0,
DWORD dwCreateFlags=0, LPSECURITY_ATTRIBUTES lpSecurityAttrs=NULL);

M_ctrlW this is controls a pointer or a control entity, you confirm, the estimate is identified become the second
Multi-threaded use AfxBeginThread, used in the thread window control will lead to all sorts of problems, such a development is not recommended,
It is recommended to use a separate thread, USES the message mechanism,

This also tried, it is still a question, this is my function definition

M_ctrlW, is MFC edit box CEDIT variables
