CComboBox m_cComboSateName1,m_cComboSateName2;
CString CStemp;
m_cComboSateName1.GetWindowTextW(CStemp);

if (CStemp.compare("A")==0)
{
m_cComboSateName2.AddString("1A");
m_cComboSateName2.AddString("2A");
}
else if(CStemp.compare("B")==0))
{
m_cComboSateName2.AddString("1B");
m_cComboSateName2.AddString("2B");
}

//Something exactly like this,But please check the compare function or any other syntax mistake.Also check if u r using unicode or multi in case of string comparasion
