Quick CWinThread Question please

Hi All...
Not being au fait with multi threading, Id just like to get your advice,
Im starting a thread like this:

Code:

---

        m_pFileHub = AfxBeginThread(RUNTIME_CLASS(CFileHub),
                                    THREAD_PRIORITY_NORMAL,
                                    0,
                                    CREATE_SUSPENDED);

---

where m_pFileHub is a pointer to a class derived from CWinThread.
Now the compiler doesnt like it because it insists on returning a CWinThread*, not a CFileHub*.

My question is, how do I start my thread then get access to its variables and methods. I had thought I would be able to use the pointer returned by AfxBeginThread !

Thanks all for helping me
Phill

[ removed duplicate thread ]

[ Moved thread ]

Just cast the returned pointer like:

Code:

---

        m_pFileHub = (CFileHub*)AfxBeginThread(RUNTIME_CLASS(CFileHub),
                                    THREAD_PRIORITY_NORMAL,
                                    0,
                                    CREATE_SUSPENDED);

---

Or use the C++ style static_cast operator:

Code:

---

m_pFileHub = static_cast<CFileHub*>(AfxBeginThread(RUNTIME_CLASS(CFileHub),
                                    THREAD_PRIORITY_NORMAL,
                                    0,
                                    CREATE_SUSPENDED));

Thanks Guys !
Wildfrog, like the solution.. neat !

Incidently Im trying to call ::Create against a CDialog* in a function in the Threaded class.
The compiler is having non of it.

during this call:

Code:

---

m_pProgressDialog->Create(IDD_PROGRESS_DIALOG);

---

I get an ASSERTION in DLGCORE>CPP here:

Code:

---

BOOL CDialog::Create(LPCTSTR lpszTemplateName, CWnd* pParentWnd)
{
        ASSERT(HIWORD(lpszTemplateName) == 0 ||
                AfxIsValidString(lpszTemplateName));

--> -->        m_lpszTemplateName = lpszTemplateName;  // used for help
        if (HIWORD(m_lpszTemplateName) == 0 && m_nIDHelp == 0)
                m_nIDHelp = LOWORD((DWORD)m_lpszTemplateName);

#ifdef _DEBUG
        if (!_AfxCheckDialogTemplate(lpszTemplateName, FALSE))

---

Is there any reason why I cant do this in a class derived from CWinThread ?

Thanks
Phil

Did you create it as a "GUI" type thread? There are two types of threads worker threads, and GUI threads:

There's an example project on that page that might help you out (I haven't looked at the example myself).
