本文實例講述了C#經由過程WIN32 API完成嵌入法式窗體的辦法，分享給年夜家供年夜家參考。詳細以下：

這是一個不應用COM,而是經由過程WIN32 API完成的示例, 它把寫字板法式嵌在了本身的一個面板中。

這麼做能夠沒有現實意義, 由於兩個法式之前沒有停止有價值的交互, 這裡僅僅是為了演示這麼做到, 以下是具體正文過的重要源代碼。

我們把它封裝到一個類中:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Diagnostics; 
using System.Runtime.InteropServices; 
using System.Windows.Forms; 
namespace System.Windows.Forms 
{ 
  class InsertWindow 
  { 
    /// <summary> 
    /// 將法式嵌入窗體 
    /// </summary> 
    /// <param name="pW">容器</param> 
    /// <param name="appname">法式名</param> 
    public InsertWindow(Panel pW,string appname) 
    { 
      this.pan = pW; 
      this.LoadEvent(appname); 
      pane(); 
    } 
    ~InsertWindow() 
    { 
      if (m_innerProcess!=null) 
      { 
        m_innerProcess.Dispose(); 
      } 
    } 
    #region 函數和變量聲明

    const Int32 GWL_STYLE = -16; 
    const Int32 WS_BORDER = (Int32)0x00800000L;

    const Int32 SWP_NOMOVE = 0x0002; 
    const Int32 SWP_NOSIZE = 0x0001; 
    const Int32 SWP_NOZORDER = 0x0004; 
    const Int32 SWP_FRAMECHANGED = 0x0020; 
    const Int32 SW_MAXIMIZE = 3; 
    IntPtr HWND_NOTOPMOST = new IntPtr(-2); 
    // 目的運用法式的過程. 
    Process m_innerProcess = null; 
    #endregion 
    #region 容器 
    private Panel pan = null; 
    public Panel panel1 
    { 
      set { pan = value; } 
      get { return pan; } 
    } 
    private void pane() 
    { 
      panel1.Anchor = AnchorStyles.Left | AnchorStyles.Top | 
       AnchorStyles.Right | AnchorStyles.Bottom; 
      panel1.Resize += new EventHandler(panel1_Resize); 
    } 
    private void panel1_Resize(object sender, EventArgs e) 
    { 
      // 設置目的運用法式的窗體款式. 
      IntPtr innerWnd = m_innerProcess.MainWindowHandle; 
      SetWindowPos(innerWnd, IntPtr.Zero, 0, 0, 
        panel1.ClientSize.Width, panel1.ClientSize.Height, 
        SWP_NOZORDER); 
    } 
    #endregion 
    #region 響應事宜 
    private void LoadEvent(string appFile) 
    { 
      // 啟動目的運用法式. 
      m_innerProcess = Process.Start(appFile); 
      m_innerProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; //隱蔽 
      // 期待, 直到誰人法式曾經完整啟動.  
      m_innerProcess.WaitForInputIdle(); 
      // 目的運用法式的主窗體. 
      IntPtr innerWnd = m_innerProcess.MainWindowHandle; 
      // 設置目的運用法式的主窗體的父親(為我們的窗體). 
      SetParent(innerWnd, panel1.Handle); 
      // 除去窗體邊框. 
      Int32 wndStyle = GetWindowLong(innerWnd, GWL_STYLE); 
      wndStyle &= ~WS_BORDER; 
      wndStyle &= ~WS_THICKFRAME; 
      SetWindowLong(innerWnd, GWL_STYLE, wndStyle); 
      SetWindowPos(innerWnd, IntPtr.Zero, 0, 0, 0, 0, 
        SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED); 
      // 在Resize事宜中更新目的運用法式的窗體尺寸. 
      panel1_Resize(panel1, null); 
    } 
#endregion
  }
}

然後在窗口的load事宜中參加具體代碼以下:

using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.Runtime; 
using System.Runtime.InteropServices; 
using System.Diagnostics; 
namespace 將法式窗口嵌入就任務欄中 
{ 
  public partial class Form1 : Form 
  { 
    private System.Windows.Forms.Panel panel1; 
    public Form1() 
    { 
      InitializeComponent(); 
      this.panel1 = new System.Windows.Forms.Panel(); 
      this.SuspendLayout(); 
      //  
      // panel1 
      //  
      this.panel1.Dock = System.Windows.Forms.DockStyle.Fill; 
      this.panel1.Location = new System.Drawing.Point(0, 0); 
      this.panel1.Name = "panel1"; 
      this.panel1.Size = new System.Drawing.Size(292, 273); 
      this.panel1.TabIndex = 0; 
      this.Controls.Add(this.panel1); 
      Load += new EventHandler(Form1_Load); 
    } 
    private void Form1_Load(object sender, EventArgs e) 
    { 
      //string sPath = Environment.GetEnvironmentVariable("windir");//獲得體系變量 windir(windows)  
      const string appFile = 
        "C:\\Program Files\\Windows NT\\Accessories\\wordpad.exe"; 
      InsertWindow insertwin = new InsertWindow(panel1, appFile); 
    } 
  } 
}
