Sure.  Add a constructor to your class:

Code Select Expand


class PopotteMain:CWINDOW
{
      declare PopotteMain();
...//the rest of your class
}

PopotteMain::PopotteMain()
{
    m_Red = NULL;
}

And in your OnSize handler check to make sure the control exists.

Code Select Expand


PopotteMain::OnSize(INT nType,INT cx,INT cy),INT
{
if m_Red
            m_Red->SetSize(10,70,cx-22,cy-81);

//resize the toolbar
m_tool.Resize();

return true;
}


Windows fires off OnSize events as soon as the window is created, long before you are creating the RichEdit control.  Which is why we use constructors to set pointers to NULL.  That's what a constructor is for.

Hi Krypt!
Nice to see that you are porting your Popotte program to Aurora
