问题描述
1.总是提示输入大括号，但并不缺少大括号，而且输入后还是会有一样的提示2.
if ( hWnd ) { TCHAR szBuf[MAX_CLASSNAME]; // Retrieve window class name GetClassName(hWnd szBuf,MAX_CLASSNAME); if ( lstrcmpi( szBuf, _T( 'msctls_updown32' ) ) == 0 ) // Up-down is found { DWORD dwStyle = GetWindowLong( hWnd, GWL_STYLE ); if ( ( dwStyle & UDS_ALIGNRIGHT || dwStyle & UDS_ALIGNLEFT ) && SendMessage( hWnd, UDM_GETBUDDY, 0, 0L ) == (LONG)m_hWnd ) { RECT rc; GetWindowRect( hWnd, &rc ); const int nEdge = GetSystemMetrics( SM_CXEDGE ); if ( dwStyle & UDS_ALIGNRIGHT ) rect.right += ( rc.right - rc.left ) - nEdge; else // UDS_ALIGNLEFT rect.left -= ( rc.right - rc.left ) - nEdge; HDC hDC = GetDC( hWnd ); // We must draw the lines onto spin control DC COLORREF clr = GetSysColor( m_nState & dsHoverMask ? COLOR_3DDKSHADOW : COLOR_3DHIGHLIGHT ); if ( !IsWindowEnabled( m_hWnd ) ) clr = GetSysColor( COLOR_3DFACE ); FillSolidRect( hDC, 1, 1, rc.right - rc.left - nEdge - 1, 1, clr ); if ( dwStyle & UDS_ALIGNLEFT ) FillSolidRect( hDC, 1, 1, 1, rc.bottom - rc.top - nEdge - 1, clr ); ReleaseDC( hWnd, hDC ); } } } 3.错误提示
问题解答
回答1：szBuf前少了个逗号了吧？
回答2：编译器的提醒不是给人看的，可以试试clang
回答3：如果编译器能够智能指出错误，还要程序员干什么。
