Question

我有一个winform应用程序（.NET 2.0 C＃）。从这个应用程序，我想启动另一个进程（另一个winform应用程序）并将其停靠到我的窗口（或至少让它看起来像停靠）。到目前为止，我只能找到有关对接控件的信息，而不是单独进程中的窗口。我的第一个想法是获取窗口的句柄并使用非托管系统调用将窗口的高度/宽度和位置设置到我的停靠区域。但在我开始之前，我想检查一下你们中是否有人做过类似的事情。我可以访问我想要停靠的应用程序的源代码，但如果可以避免它，我宁愿不做任何更改。我对父应用程序的完整编程控制。有什么建议？提前谢谢！

Answer 1

我之前使用的解决方案是将应用程序窗口设置为您要将其停靠的控件的子窗口。

using System.Diagnostics;
using System.Runtime.InteropServices;

private Process pDocked;
private IntPtr hWndOriginalParent;
private IntPtr hWndDocked;

[DllImport("user32.dll")]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

[DllImport("user32.dll", SetLastError = true)]
public static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

private void dockIt()
{
    if (hWndDocked != IntPtr.Zero) //don't do anything if there's already a window docked.
        return;
    hWndParent = IntPtr.Zero;

    pDocked = Process.Start(@"notepad");
    while (hWndDocked == IntPtr.Zero)
    {
        pDocked.WaitForInputIdle(1000); //wait for the window to be ready for input;
        pDocked.Refresh();              //update process info
        if (pDocked.HasExited)
        {
            return; //abort if the process finished before we got a handle.
        }
        hWndDocked = pDocked.MainWindowHandle;  //cache the window handle
    }
    //Windows API call to change the parent of the target window.
    //It returns the hWnd of the window's parent prior to this call.
    hWndOriginalParent = SetParent(hWndDocked, Panel1.Handle);

    //Wire up the event to keep the window sized to match the control
    Panel1.SizeChanged += new EventHandler(Panel1_Resize);
    //Perform an initial call to set the size.
    Panel1_Resize(new Object(), new EventArgs());
}

private void undockIt()
{
    //Restores the application to it's original parent.
    SetParent(hWndDocked, hWndOriginalParent);
}

private void Panel1_Resize(object sender, EventArgs e)
{
    //Change the docked windows size to match its parent's size. 
    MoveWindow(hWndDocked, 0, 0, Panel1.Width, Panel1.Height, true);
}

*在答案中添加一些解决方案.. * *

此代码帮助我在Windows窗体中停靠了一些可执行文件。像NotePad，Excel，word，Acrobat reader等等......

但它不适用于某些应用程序。有时当你开始某个应用程序的进程....等待空闲时间...并尝试获取它的mainWindowHandle ....直到主窗口句柄变为空..... .....

所以我做了一个解决这个问题的技巧

如果你将主窗口句柄作为null ...然后搜索sytem上的所有运行进程并找到你的进程...然后获取进程的主要进程并将set面板作为其父进程。

            ProcessStartInfo info = new ProcessStartInfo();
            info.FileName = "xxxxxxxxxxxx.exe";
            info.Arguments = "yyyyyyyyyy";
            info.UseShellExecute = true;
            info.CreateNoWindow = true;
            info.WindowStyle = ProcessWindowStyle.Maximized;
            info.RedirectStandardInput = false;
            info.RedirectStandardOutput = false;
            info.RedirectStandardError = false;

            System.Diagnostics.Process p = System.Diagnostics.Process.Start(info); 

            p.WaitForInputIdle();
            Thread.Sleep(3000);

            Process[] p1 ;
        if(p.MainWindowHandle == null)
        {
            List<String> arrString = new List<String>();
            foreach (Process p1 in Process.GetProcesses())
            {
                // Console.WriteLine(p1.MainWindowHandle);
                arrString.Add(Convert.ToString(p1.ProcessName));
            }
            p1 = Process.GetProcessesByName("xxxxxxxxxxxx");
            //p.WaitForInputIdle();
            Thread.Sleep(5000);
           SetParent(p1[0].MainWindowHandle, this.panel2.Handle);
        }
         else
        {
           SetParent(p.MainWindowHandle, this.panel2.Handle);
        }

这比我希望的要笨重，但到目前为止工作。我正在使用系统调用强制子窗口在反映停靠区域的位置。它还没有完美运作。我得到HWND_TOPMOST引起的一些奇怪的事情，我仍然需要添加逻辑来阻止用户直接移动子窗口。

    //This is my docking window
    private System.Diagnostics.Process notepad;
    private void windowDockTest()
    {
        /*
         * Docking notepad to panel2 of the splitcontainer
         */

        //if panel2 moves or is resized, call the docking function
        spcScript.Panel2.Move += new EventHandler(Panel2_Resize);
        spcScript.Panel2.SizeChanged += new EventHandler(Panel2_Resize);

        //Call the docking function if main form is moved
        this.LocationChanged += new EventHandler(Panel2_Resize);

        //Start the notepad process
        notepad = new System.Diagnostics.Process();
        notepad.StartInfo.FileName = "notepad";
        notepad.Start();

        //Wait a second for notpad to fully load
        notepad.WaitForInputIdle(1000);

        //Dock it
        Panel2_Resize(new Object(), new EventArgs());
    }

    void Panel2_Resize(object sender, EventArgs e)
    {
        //Get the screen location of panel2
        Rectangle r = spcScript.Panel2.RectangleToScreen(spcScript.Panel2.ClientRectangle);

        //Dock it
        redock(notepad.MainWindowHandle, r.X, r.Y, r.Width, r.Height);
    }

    [DllImport("user32.dll")]
    public static extern IntPtr SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int x, int Y, int cx, int cy, int wFlags);
    public static void redock(IntPtr handle, int x, int y, int width, int height)
    {
        IntPtr HWND_TOPMOST = new IntPtr(-1);
        const short SWP_NOACTIVATE = 0x0010;

        SetWindowPos(handle,HWND_TOPMOST, x, y, width, height,SWP_NOACTIVATE);
    }

在另一个窗口内停靠窗口
