simple winapi spin control

Question

I am trying to make a simple spin control and edit box in WTL &/ winapi. and this does not work properly, because I only see 0 as initial value and the arrows don t work, code here: ``` HWND spin = GetDlgItem(IDC_SPIN1); HWND edit = GetDlgItem(IDC_RANDOM_EDIT); ::SendMessage(spin, UDM_SETBUDDY, (WPARAM)edit, 0); //set buddy ::SendMessage(spin, UDM_SETRANGE, MAKELPARAM(0,100), 0); //interval ::SendMessage(spin, UDM_SETBASE, 10, 0); //initial position ```

Accepted Answer

You have your wparam and lparam reversed. You also have the low and high words reversed.

```
::SendMessage(spin, UDM_SETRANGE, 0, MAKELPARAM(100,0)); //interval
```

See the definitions of `UDM_SETRANGE` and `MAKELPARAM`.
