Getting\Setting EditItem from Combobox Using SendMessage


I have a handle to a combobox in a different process, I want to:
1. Get the item with the X index
2. Be able to set the selected item to Y (index)

I know how to do it for Listview controls, and I'm sure its possible
for Combobox's as well,
Any ideas?

Well, thanks for all your relpies(!!#$#@%!)

Anyway, I got is sloved so I figured why not post for everyone...
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError =
public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int
wParam, string lParam);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError =
public static extern IntPtr SendRefMessage(IntPtr hWnd, uint Msg, int
wParam, StringBuilder lParam);

uint CB_GETLBTEXT = 0x0148;
uint CB_SETCURSEL = 0x014E;

public string GetComboItem(int index)
StringBuilder ssb = new StringBuilder(256, 256);
SendRefMessage(this.Handle, CB_GETLBTEXT, index, ssb);
return ssb.ToString();

public void SetComboItem(int index)
SendMessage(this.Handle, CB_SETCURSEL, index,"0");
