title: MFC ComboBox dropdown list too short
body: <p>I have dropped <code>ComboBox</code> on dialog form. Also I have added some text to it:</p>
  
  <pre><code>BOOL CMyAppDlg::OnInitDialog()
  {
  
      CComboBox *combo= (CComboBox *)GetDlgItem(IDC_COMBO_TT);
      combo-&gt;AddString("s1");
      combo-&gt;AddString("s2");
  
  //...
  return TRUE;
  }
  </code></pre>
  
  <p>When I drop down ComboBox it shows only one selection line and adds arrows to select other items. How to increase dropdown size?</p>
