problems populating combobox

I give up!! I'm having problems populating a combobox with the numbers 1 - 10.  Anybody see anything wrong with this code.  It's from OnInitDialog.  The combobox is on a dialog created using the ATL wizard. First call to SendMessage returns 0.  GetLastError() returns 0.  Second call to SendMessage return -1, which is right because the combobox was not properly populated.

const ULONG MAX_POSSIBLE_MIGS = 10;


     HWND h_Combo = GetDlgItem(IDC_MAXMIGS_COMBO);
     //populate the combo box control
     for( int x = 1; x <= MAX_POSSIBLE_MIGS; ++x )
     {    
          COMBOBOXEXITEM item = {0};
          item.mask = CBEIF_TEXT;
          item.iItem =   - 1;
          TCHAR buff[10] = {0};
          _itow( x, buff, 10 );
          item.pszText = buff;
//          item.cchTextMax = (lstrlen(buff)+1);
     
          long ret = SendMessage( h_Combo, CBEM_INSERTITEM, NULL, reinterpret_cast<LPARAM>(&item));
          long err = GetLastError();
          m_vComboItems.push_back(&item);
     }
     ///set the default concurrent migrations to 3
     HWND h = GetDlgItem(IDC_MAXMIGS_COMBO);
    long ret =     SendMessage(h, CB_SETCURSEL,  static_cast<WPARAM>(4), NULL  );
     return FALSE;  // Let the system set the focus

Try:

item.iItem = x - 1;

instead of
item.iItem = - 1;

also ( not related to question )
         
m_vComboItems.push_back(&item);  doesn't look good.

item is local variable and you are storing pointer to it.  So how are you planing to use it, once you left your loop it doesn't point to anything. ?????

mblat,
I used CB_ADDSTRING and everything worked fine.  Thanks for your willingness to help.

p.s. I tried item.iItem = (x-1) and it didn't work...tried that before I posted the question.
