Still you can send standard window messages if you want to communicate with a view.<br />
Something like:<br />
<br />
theApp.m_pMainWnd-&gt;SendMes<wbr />sage(WM_US<wbr />ER+1, somedata, somedata);<br />

The problem was that I forgot to create the thread as suspended, set its Main Window pointer, and then resume.<br />
Still, it would be unfair to deny the answer points to Alex.<br />

<div class="content wysiwyg-content">
I have the following piece of code:<br />
<br />
CWnd *CMyApp::GetView()<br />
{<br />
&nbsp; CMainFrame *pFrm = (CMainFrame *)AfxGetMainWnd();<br />
&nbsp; return pFrm-&gt;GetActiveView();<br />
}<br />
<br />
It works fine from the main thread of the application. For some reason, I cannot call this function from a worker thread.<br />
<br />
I have heard there is a problem when AfxGetMainWnd is called from a worker thread. Is this correct, and if so, why and what kind of problems?<br />
