I need to access a dialog box from a thread outside of the dialog box class.<br />
<br />
in portai.cpp, the thread is called like this:<br />
m_pReaderThread = AfxBeginThread(ReaderThrea<wbr />d, (LPVOID)this);<br />
<br />
m_pReaderThread is declared like this in portai.h &nbsp;CWinThread* m_pReaderThread; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
and the thread is declared as UINT CiPortAI::ReaderThread(LPV<wbr />OID pThis)<br />
<br />
I want to be able to update text boxes on my main dialog box from within the thread. How do I do this?
