通过 WIN32 API 实现嵌入程序窗体

写了一个不使用 COM, 而是通过 WIN32 API 实现的示例, 它把写字板程序嵌在了自己的一个面板中.

这么做可能没有实际意义, 因为两个程序之前没有进行有价值的交互, 这里仅仅是为了演示这么做到, 以下是详细注释过的主要源代码.

我把它封装到一个类中:

1. usingSystem;
2. usingSystem.Collections.Generic;
3. usingSystem.Linq;
4. usingSystem.Text;
5. usingSystem.Diagnostics;
6. usingSystem.Runtime.InteropServices;
7. usingSystem.Windows.Forms;
8. namespaceSystem.Windows.Forms
9. {
10. classInsertWindow
11. {
12. ///<summary>
13. ///将程序嵌入窗体
14. ///</summary>
15. ///<paramname="pW">容器</param>
16. ///<paramname="appname">程序名</param>
17. publicInsertWindow(PanelpW,stringappname)
18. {
19. this.pan=pW;
20. this.LoadEvent(appname);
21. pane();
22. }
24. ~InsertWindow()
25. {
26. if(m_innerPRocess!=null)
27. {
28. m_innerProcess.Dispose();
29. }
30. }
32. #region函数和变量声明
33. /*

37. [DllImport("user32.dll")]
38. staticexternIntPtrSetParent(IntPtrhWndChild,
39. IntPtrhWndNewParent
40. );
42. [DllImport("user32.dll")]
43. staticexternInt32GetWindowLong(IntPtrhWnd,
44. Int32nIndex
45. );
47. [DllImport("user32.dll")]
48. staticexternInt32SetWindowLong(IntPtrhWnd,

50. Int32dwNewLong
51. );
53. [DllImport("user32.dll")]
54. staticexternInt32SetWindowPos(IntPtrhWnd,
55. IntPtrhWndInsertAfter,
56. Int32X,
57. Int32Y,
58. Int32cx,
59. Int32cy,
60. UInt32uFlags
61. );
63. /*

66. constInt32GWL_STYLE=-16;
67. constInt32WS_BORDER=(Int32)0x00800000L;
68. constInt32WS_THICKFRAME=(Int32)0x00040000L;

76. IntPtrHWND_NOTOPMOST=newIntPtr(-2);
78. //目标应用程序的进程.
79. Processm_innerProcess=null;
80. #endregion
82. #region容器
83. privatePanelpan=null;
84. publicPanelpanel1
85. {
86. set{pan=value;}
87. get{returnpan;}
88. }
89. privatevoidpane()
90. {
91. panel1.Anchor=AnchorStyles.Left|AnchorStyles.Top|
92. AnchorStyles.Right|AnchorStyles.Bottom;
93. panel1.Resize+=newEventHandler(panel1_Resize);
94. }
95. privatevoidpanel1_Resize(objectsender,EventArgse)
96. {
97. //设置目标应用程序的窗体样式.
99. IntPtrinnerWnd=m_innerProcess.MainWindowHandle;
100. SetWindowPos(innerWnd,IntPtr.Zero,0,0,
101. panel1.ClientSize.Width,panel1.ClientSize.Height,
102. SWP_NOZORDER);
103. }
104. #endregion
106. #region相应事件
107. privatevoidLoadEvent(stringappFile)
108. {
110. //启动目标应用程序.
111. m_innerProcess=Process.Start(appFile);
112. m_innerProcess.StartInfo.WindowStyle=ProcessWindowStyle.Hidden;//隐藏
113. //等待,直到那个程序已经完全启动.
114. m_innerProcess.WaitForInputIdle();
116. //目标应用程序的主窗体.
117. IntPtrinnerWnd=m_innerProcess.MainWindowHandle;
119. //设置目标应用程序的主窗体的父亲(为我们的窗体).
120. SetParent(innerWnd,panel1.Handle);
122. //除去窗体边框.
123. Int32wndStyle=GetWindowLong(innerWnd,GWL_STYLE);
124. wndStyle&=~WS_BORDER;
125. wndStyle&=~WS_THICKFRAME;
126. SetWindowLong(innerWnd,GWL_STYLE,wndStyle);
127. SetWindowPos(innerWnd,IntPtr.Zero,0,0,0,0,
128. SWP_NOMOVE|SWP_NOSIZE|SWP_NOZORDER|SWP_FRAMECHANGED);
130. //在Resize事件中更新目标应用程序的窗体尺寸.
131. panel1_Resize(panel1,null);
132. }
133. #endregion
134. }
137. }

然后在 窗口的 load事件中 加入

详细代码 如下:

1. usingSystem;
2. usingSystem.Collections.Generic;
3. usingSystem.ComponentModel;
4. usingSystem.Data;
5. usingSystem.Drawing;
6. usingSystem.Linq;
7. usingSystem.Text;
8. usingSystem.Windows.Forms;
9. usingSystem.Runtime;
10. usingSystem.Runtime.InteropServices;
11. usingSystem.Diagnostics;
13. namespace将程序窗口嵌入到任务栏中
14. {
15. publicpartialclassForm1:Form
16. {
17. privateSystem.Windows.Forms.Panelpanel1;
18. publicForm1()
19. {
20. InitializeComponent();
21. this.panel1=newSystem.Windows.Forms.Panel();
22. this.SuspendLayout();
23. //
24. //panel1
25. //
26. this.panel1.Dock=System.Windows.Forms.DockStyle.Fill;
27. this.panel1.Location=newSystem.Drawing.Point(0,0);
28. this.panel1.Name="panel1";
29. this.panel1.Size=newSystem.Drawing.Size(292,273);
30. this.panel1.TabIndex=0;
31. this.Controls.Add(this.panel1);
33. Load+=newEventHandler(Form1_Load);
34. }
36. privatevoidForm1_Load(objectsender,EventArgse)
37. {
38. //stringsPath=Environment.GetEnvironmentVariable("windir");//获取系统变量windir(windows)
39. conststringappFile=
40. "C://ProgramFiles//WindowsNT//accessories//Wordpad.exe";
41. InsertWindowinsertwin=newInsertWindow(panel1,appFile);
43. }
46. }
47. }
