GetWindowLong 和 SetWindowLong 都有什么参数？具体怎么用？

這個是我們之前用的例子，給您參考看看 應該是非常簡單明了 DWORD dwStyle=::GetWindowLong(AA->Handle,GWL_STYLE); dwStyle=dwStyle|TVS_CHECKBOXES; SetWindowLong(AA->Handle,GWL_STYLE,dwStyle);

LONG SetWindowLong( HWND hWnd, // handle of window int nIndex, // offset of value to set LONG dwNewLong // new value ); LONG GetWindowLong( HWND hWnd, // handle of window int nIndex // offset of value to retrieve ); read the sdk!
