在C＃中使用SetWindowPos来移动窗口 [英] Using SetWindowPos in C# to move windows around

问题描述

我有以下code：

namespace WindowMover
{
    using System.Windows.Forms;

    static class Logic
    {
        [DllImport("user32.dll", EntryPoint = "SetWindowPos")]
        public static extern IntPtr SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int Y, int cx, int cy, int wFlags);

        public static void Move()
        {
            const short SWP_NOMOVE = 0X2;
            const short SWP_NOSIZE = 1;
            const short SWP_NOZORDER = 0X4;
            const int SWP_SHOWWINDOW = 0x0040;

            Process[] processes = Process.GetProcesses(".");
            foreach (var process in processes)
            {
                var handle = process.MainWindowHandle;
                var form = Control.FromHandle(handle);

                if (form == null) continue;

                SetWindowPos(handle, 0, 0, 0, form.Bounds.Width, form.Bounds.Height, SWP_NOZORDER | SWP_SHOWWINDOW);
            }
        }
    }
}

这应该是我的桌面上每移动窗口，0,0（X，Y），并保持相同的尺寸。
我的问题是，只有调用应用程序（建于C＃）是越来越移动。

This is supposed to move every window on my desktop to 0,0 (x,y) and keep the same sizes. My problem is that only the calling app (built in C#) is getting moved.

我应该使用比Control.FromHandle（IntPtr的）别的其他？这会不会只找DOTNET控件？如果是这样，我应该用什么呢？

Should I be using something else other than Control.FromHandle(IntPtr)? Will this only find dotnet controls? If so what should I use?

此外，在SetWindowPos二0只是一个随机INT我坚守在那里，我不知道用什么INT hWndInsertAfter

Also, the second 0 in SetWindowPos was just a random int I stick in there, I'm not sure what to use for int hWndInsertAfter

有关使用多个窗口像洋泾浜的流程是什么？

What about processes with multiple windows like pidgin?

推荐答案

只需拿出你的Control.FromHandle和形式== NULL检查。你应该能够只是做：

Just take out your Control.FromHandle and the form == null check. You should be able to just do:

IntPtr handle = process.MainWindowHandle;
if (handle != IntPtr.Zero)
{
    SetWindowPos(handle, 0, 0, 0, 0, 0, SWP_NOZORDER | SWP_NOSIZE | SWP_SHOWWINDOW);
}

如果您添加SWP_NOSIZE，也不会改变窗口大小，但仍将重新定位。

If you add SWP_NOSIZE, it will not resize the window, but will still reposition it.

如果你想影响所有的窗口，而不仅仅是主窗口，每一个过程中，你可能要考虑使用的 EnumWindows的而不是HTML>的P / Invoke通过进程列表进行迭代，并使用MainWindowHandle。

If you want to effect all windows, not just the main window, of each process, you might want to consider using P/Invoke with EnumWindows instead of iterating through the Process list and using MainWindowHandle.
