是否有可能为.net应用程序来获取所有的窗口句柄当前打开，和移动/调整这些窗口？

Is it possible for a .NET application to grab all the window handles currently open, and move/resize these windows?

我倒是pretty的确定它可能使用P / Invoke，但我不知道是否有一些管理code包装这个功能。

I'd pretty sure its possible using P/Invoke, but I was wondering if there were some managed code wrappers for this functionality.

推荐答案

是的，这是可以使用Windows API。

Yes, it is possible using the Windows API.

这篇文章对如何从活动进程的所有窗口句柄信息：http://www.c-sharpcorner.com/Forums/ShowMessages.aspx?ThreadID=35545

This post has information on how to get all window handles from active processes: http://www.c-sharpcorner.com/Forums/ShowMessages.aspx?ThreadID=35545

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
       Process[] procs = Process.GetProcesses();
       IntPtr hWnd;
       foreach(Process proc in procs)
       {
          if ((hWnd = proc.MainWindowHandle) != IntPtr.Zero)
          {
             Console.WriteLine("{0} : {1}", proc.ProcessName, hWnd);
          }
       }         
    }
 }

然后你可以移动使用Windows API的窗口：http://www.devasp.net/net/articles/display/689.html

[DllImport("User32.dll", ExactSpelling = true, CharSet = System.Runtime.InteropServices.CharSet.Auto)]
        private static extern bool MoveWindow(IntPtr hWnd, int x, int y, int cx, int cy, bool repaint);

...

MoveWindow((IntPtr)handle, (trackBar1.Value*80), 20 , (trackBar1.Value*80)-800, 120, true);

下面是参数的MoveWindow功能：

Here are the parameters for the MoveWindow function:

为了移动窗口，我们使用   中的MoveWindow函数，该函数   窗口句柄，所述坐标   为上角，以及   希望的宽度和高度   窗口中，根据屏幕上   坐标。该功能的MoveWindow   定义为：

In order to move the window, we use the MoveWindow function, which takes the window handle, the co-ordinates for the top corner, as well as the desired width and height of the window, based on the screen co-ordinates. The MoveWindow function is defined as:

的MoveWindow（HWND的HWND，诠释nX的，INT   纽约，INT nWidth，nHeight参数INT，BOOL   bRepaint）;

MoveWindow(HWND hWnd, int nX, int nY, int nWidth, int nHeight, BOOL bRepaint);

在bRepaint标志   确定客户端区   应该无效，引起   要发送WM_PAINT消息，允许   客户区重新绘制。作为   一旁，屏幕坐标可以是   使用类似于一个呼叫得到   GetClientRect（GetDesktopWindow（），   ＆安培; rcDesktop）与rcDesktop是一个   RECT类型的变量，经过   参考。

The bRepaint flag determines whether the client area should be invalidated, causing a WM_PAINT message to be sent, allowing the client area to be repainted. As an aside, the screen co-ordinates can be obtained using a call similar to GetClientRect(GetDesktopWindow(), &rcDesktop) with rcDesktop being a variable of type RECT, passed by reference.
