Answer 5

更改auto arrange不能反映在菜单上 但可以拖动图标检查效果

Answer 6

我试了试，怎么不行啊~~
调用EnableAutoArrange这个方法，怎么连桌面图标都不能拖动了啊~
对了，楼上，我说错了应该是“自动排列”和“对齐到网格”
再给说一下好吗？
分给定你了~~

Answer 7

EnableAutoArrange后确实不能拖动图标 要不怎么自动排列
下边是对齐到网格的代码
const int LVM_First = 0x1000;
        const int LVM_SETEXTENDEDLISTVIEWSTYLE = LVM_First + 54;
        const int LVS_EX_SNAPTOGRID = 0x00080000;        [DllImport("user32.dll", CharSet = CharSet.Unicode)]
        public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);        private void EnableAlignToGrid(object sender, EventArgs e)
        {
            int hwnd, child;
            hwnd = FindWindow("progman", 0);
            hwnd = FindWindowEx(hwnd, 0, "shelldll_defview", 0);
            child = FindWindowEx(hwnd, 0, "SysListView32", 0);
            SendMessage(new IntPtr(child), LVM_SETEXTENDEDLISTVIEWSTYLE, new IntPtr(LVS_EX_SNAPTOGRID), new IntPtr(LVS_EX_SNAPTOGRID));
        }        private void DisableAlignToGrid(object sender, EventArgs e)
        {
            int hwnd, child;
            hwnd = FindWindow("progman", 0);
            hwnd = FindWindowEx(hwnd, 0, "shelldll_defview", 0);
            child = FindWindowEx(hwnd, 0, "SysListView32", 0);
            SendMessage(new IntPtr(child), LVM_SETEXTENDEDLISTVIEWSTYLE, new IntPtr(LVS_EX_SNAPTOGRID), IntPtr.Zero);
        }

Answer 8

对齐网格很正确啊！！
谢谢，Macosx了
你真厉害啊~~
