Just one random example out of the committed Winefile patch:

- int idx = ListBox_AddString(hlbox, infoStr);
- ListBox_SetItemData(hlbox, idx, pTxt);
+ int idx = SendMessage(hlbox, LB_ADDSTRING, 0L, (LPARAM)infoStr);
+ SendMessage(hlbox, LB_SETITEMDATA, idx, (LPARAM) pTxt);

You can't tell us those SendMessage calls are cleaner and more easy to
understand. They contain those ugly (LPARAM) type casts, unused "0L"
wparam parameters and result in longer, less readable code.
