抓住并从.net应用程序中移动应用程序窗口？ [英] Grab and move application windows from a .NET app?

问题描述

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.

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：<一href="http://www.devasp.net/net/articles/display/689.html">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.
