Re: multi-thread problem

   I think the problem can be corrected with a simple cast statement. And I
believe it is more of C++ issue, but I haven't used cast myself in some of
the C++ I've written so far except for this MFC program. I am learning and
would like to understand how to write the cast for this situation. I need to
convert from the main dialog to this "long int" from the ActiveX class. And
that is what I am not understanding. Could the cast be written as simple as
this statement:

 CThreadTestDlg* pNum = ( m_xActxCtrl *)long pNum;

--------------------------------------------

error C2440: 'type cast' : cannot convert from 'long CThreadTestDlg::*' to
'long'

-------------------------------------------
The code written with the above statement:

UINT CThreadTestDlg::Thread1(LPVOID lParam)
{
 CThreadTestDlg* pDlg = (CThreadTestDlg *)lParam;
CThreadTestDlg* pNum = ( m_xActxCtrl *)long pNum;

ActxCtrl m_xActxCtrl;

 m_xActxCtrl.Open(); // open ActxCtrl

 pNum = m_xActxCtrl.MemFunction();

 m_xActxCtrl.Close(); // close ActxCtrl

 pDlg->PostMessage(UWM_THREAD_FINISHED, (WPARAM)0, (LPARAM) pNum);

 return 0;
}

  I haven't tried this code yet, but I'll see how it goes.
