Hey Guys,
  I am actually trying to use MoveWindow for a comboBox in MFC. Here is
the scenario

My ComboBox is already populated with some values before moving it and
the default value is been set to for example "abc". But "abc" is not a
part of the dropdown list. After this I added "abcd" to the existing
list and moved the combobox using the MoveWindow(CRect) command. Now
the default value changes to "abcd" after the move. I feel that the
MoveWindow command actually after moving the combobox is searching for
the prefix "abc" and displays whatever it finds. If that is true, then
clearly it is a bug or am i missing something? The code is below. Can
someone tell me if they've ever run into a scenario like this? Any help
would be greatly appreciated..Thanks a ton in advance.

BOOL CComboDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    // Add "About..." menu item to system menu.

    // IDM_ABOUTBOX must be in the system command range.
    ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
    ASSERT(IDM_ABOUTBOX < 0xF000);

    CMenu* pSysMenu = GetSystemMenu(FALSE);
    if (pSysMenu != NULL)
    {
        CString strAboutMenu;
        strAboutMenu.LoadString(IDS_ABOUTBOX);
        if (!strAboutMenu.IsEmpty())
        {
            pSysMenu->AppendMenu(MF_SEPARATOR);
            pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
        }
    }

    m_ctlCombo.AddString("fgh");
    m_ctlCombo.AddString("ikl");
    m_ctlCombo.SetWindowText("abc");
    // Set the icon for this dialog. The framework does this
automatically
    // when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE); // Set big icon
    SetIcon(m_hIcon, FALSE); // Set small icon

    // TODO: Add extra initialization here

    return TRUE; // return TRUE unless you set the focus to a control
}

void CComboDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
    if ((nID & 0xFFF0) == IDM_ABOUTBOX)
    {
        CAboutDlg dlgAbout;
        dlgAbout.DoModal();
    }
    else
    {
        CDialog::OnSysCommand(nID, lParam);
    }
}

// If you add a minimize button to your dialog, you will need the code
below
// to draw the icon. For MFC applications using the document/view
model,
// this is automatically done for you by the framework.

void CComboDlg::OnPaint()
{
    if (IsIconic())
    {
        CPaintDC dc(this); // device context for painting

        SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);

        // Center icon in client rectangle
        int cxIcon = GetSystemMetrics(SM_CXICON);
        int cyIcon = GetSystemMetrics(SM_CYICON);
        CRect rect;
        GetClientRect(&rect);
        int x = (rect.Width() - cxIcon + 1) / 2;
        int y = (rect.Height() - cyIcon + 1) / 2;

        // Draw the icon
        dc.DrawIcon(x, y, m_hIcon);
    }
    else
    {
        CDialog::OnPaint();
    }
}

void CComboDlg::OnSelchangeCombo()
{
    //m_ctlCombo.EnableWindow(false);
}

void CComboDlg::OnOK()
{
    CRect rectAccount,rectAcc;
    CString e;

    CString str;
    m_ctlCombo.GetWindowText(str);

    m_ctlCombo.AddString("abcdefg");
    m_ctlCombo.GetWindowRect(&rectAccount);
    m_ctlCombo1.GetWindowRect(&rectAcc);
    ScreenToClient(rectAccount);
    ScreenToClient(rectAcc);

    m_ctlCombo.MoveWindow(rectAcc);
    m_ctlCombo.GetWindowText(e);

}

// The system calls this to obtain the cursor to display while the user
drags
// the minimized window.
HCURSOR CComboDlg::OnQueryDragIcon()
{
    return (HCURSOR) m_hIcon;
}

Thanks,
