In this routine you query registry to combobox:

HKEY reg_key;
char buff[0xffff]; // temp buffer
DWORD bufflen=sizeof(buff);
int index;
CComboBox m_KeyList; // return value object

CString YOUR_MASTER_KEY="Software\\your_app\\your_subkey\\";
CString REG_YOUR_ENTRY="Profile";
if(RegOpenKeyEx(HKEY_CURRENT_USER,
YOUR_MASTER_KEY+REG_YOUR_ENTRY,
0,
KEY_QUERY_VALUE | KEY_ENUMERATE_SUB_KEYS,
&reg_key)!=ERROR_SUCCESS)
{
// key not found
}

index=0;
bufflen=sizeof(buff);
      while(RegEnumKeyEx(reg_key,
index,
buff,
&bufflen,0,0,0,0)==ERROR_SUCCESS)
{
      if(buff[0]!=0)
      m_KeyList.AddString(buff);
      index++;
      bufflen=sizeof(buff);
}
RegCloseKey(reg_key);
