[MFC] Comment savoir que mon Thread a fini sa tâche?

Bonjour,

Voici la classe que j'utilise pour gérer mes threads :

Code:

//------------------------------------------------------------------------------
// Implement an MFC based thread
//------------------------------------------------------------------------------
 
#ifndef _THREAD_H_
#define _THREAD_H_
 
 
#include "Afxmt.h"                  // Windows MFC for CEvent
 
 
 
 
 
class CThread
{
 
public:
 
    CThread(void);
    ~CThread(void);
 
    // Call this to change the priority of the thread
    BOOL SetPriority(int iNewPriority);
 
    // Call this to register a callback function
    void CallThis(void (*CallbackFunction)(void *pContext));
 
    // Call this to awake the thread and the callback function will be called
    BOOL AwakeThread(void *pTheContext);
 
private:
 
    CWinThread  *m_pTheThread;          // MFC wrapped thread
    CEvent      *m_pEvtWakeUpThread;    // Event used to call the user's callback
    CEvent      *m_pEvtThreadActive;    // Event used to terminates the thread
 
    BOOL        m_bThreadBusy;          // Callback function has returned
 
    void (*m_pUserCallback)(void *pContext);    // Ptr 2 user function to call
    void *m_pUserContext;                       // Ptr 2 user context as the callback function parameter
 
    static UINT TheThreadFunc(LPVOID pThreadFuncParam);
 
};
 
 
#endif	// _THREAD_H_

Pour lancer mon thread, j'utilise ce code :

Code:

1
2
3
// Start the acquisition thread
 
    m_apAcqThread[0]->AwakeThread(&m_aAcqThreadParams[0]);

avec

Code:

CThread *m_apAcqThread[MAX_NUMBER];

Comment puis je savoir que le Thread a terminé sa tâche?

Merci d'avance.
