I'm trying to add an Edit Control to MainFrame. I'm creating an
instance of CEdit in the paint message like this:

void SAFrame::OnPaint() {
CFrameWnd::OnPaint();

CEdit *PEdit = new CEdit;

PEdit->Create(ES_MULTILINE | WS_CHILD | WS_VISIBLE | WS_TABSTOP |
WS_BORDER,
CRect(10, 50, 150, 70), this, 0x1552);
}

But the control is not displayed. I think you have better ideas.

Don't call CFrameWnd::OnPaint() from within SAFrame::OnPaint(). It is not
necessary and causes an error because EndPaint() is called before you have a
chance to paint.

Move the code to create the edit control into SAFrame::OnCreate() which is
called once, not every time the window is painted.

Rename PEdit to m_edit and make it a member of SAFrame. (Not a pointer, but
a CEdit instance). Child windows like this are meant to have member
instances and not pointers (due to the way the object is destroyed).
