How do I maximize my MDI child ?

· One min read

In CMainFrame class ad the following code.

void CMainFrame::ActivateFrame(int nCmdShow)
{
    if (!m_bActivated)
    {
        m_bActivated = TRUE;
        nCmdShow = SW_SHOWMAXIMIZED;
    }

    CFrameWnd::ActivateFrame(nCmdShow);
}

where m_bActivated is a member variable of your frame object.
