I have a class CMutex which I can create and use by itself without problem. But when created in CQueue as follows:

    
class CQueue 
{
public:
	CQueue();
	~CQueue();

	byte *Get();
	void Put(byte *data);
	const Boolean IsEmpty(void);
private:
	typedef deque<byte*> MessageQueueDeque;
	MessageQueueDeque itsMessageQueue;
	CMutex Mutex;
};
    

The CMutex doesn''t seem to be able to keep it''s member variable? class CMutex { public: CMutex(); ~CMutex(); void Lock(); void Lock(const int Timeout); void Unlock(void); private: SYS_HANDLE hMutex; }; The handle seems to work fine when I create the mutex and gets assigned some kind of address. But when I subsequently call Lock() (Wait for single object) Now hMutex no longer equals anything?(cdcdcdcd) How did my class loose it''s variable? Many thanks gimp
