    // Remove all images filename
    m_adPageInfo.RemoveAt(m_tabIndex);

    // Remove the tabcontrol
    System::Windows::Forms::TabPage^% tabPage =
m_tabPageInfos[m_tabIndex]->m_tabPage;

// Here comes the strange behavior...
    this->tabControl1->Controls->Remove(tabPage);// this line decrements
m_tabIndex by one ?!!?!?!?? shall it do that? how could that be???
// so when I continue here it doesn't do what I think it should do... any
explanation on this behavior would be what I'm looking for...

    m_tabPageInfos.RemoveAt(m_tabIndex);
    --m_tabIndex;
    showAdPage(m_tabIndex);
}
