Re: CDialog minimize topic

I have my dialog and my goal is just minimze this into the taskbar as a
button ( like all the normal applications behaviore on minimized).

I'm calling to my dialog from CMatAgentMFCApp:
====================== code ==========================
/////////////////////////////////////////////////////////////////////////////
// The one and only CMatAgentMFCApp object

CMatAgentMFCApp theApp;

/////////////////////////////////////////////////////////////////////////////
// CMatAgentMFCApp initialization
BOOL CMatAgentMFCApp::InitInstance()
{
    //This ensures only one Agent is running
    // The GUID is designed to be unique - if you reuse this code in another
app - use a different GUID!
    if (CSingleInstance::Create (_T("E435FC13-3340-AA85-8CD7-556FF4A4EEBA")) ==
FALSE)
        return FALSE;

CMainFrame* pMainFrame = new CMainFrame;
    if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
        return FALSE;
    m_pMainWnd = pMainFrame;

    // For debugging (or something...)
    pMainFrame->ActivateFrame();
return TRUE;
}

void CMatAgentMFCApp::OnRead( )
{
CListViewDlg dlg;
int nResponse = dlg.DoModal();
}

I have this:CListViewDlg.cpp
