C# 实现磁性窗口(附源码和程序)
实现并封装了磁性窗口类MagneticMagnager,实现磁性窗口仅仅需要调用一行代码： MagneticMagnager test2 = new MagneticMagnager(this, fm2, MagneticPosition.Top); 插图： 具体操作： 1.新建winform项目MagneticForm，并添加磁性窗口操作类MagneticMagnager： [c-sharp] view plaincopy 1. using System; 2. using System.Drawing; 3. 4. namespace System.Windows.Forms 5. { 6. public class MagneticMagnager 7. { 8. MagneticPosition Pos;//位置属性 9. Form MainForm, ChildForm; 10. bool IsFirstPos;//是否第一次定位ChildForm子窗体 11. public int step;//磁性子窗体ChildForm移动步长 12. public Point LocationPt;//定位点 13. delegate void LocationDel();//移动子窗体的委托 14. public MagneticMagnager(Form _MainForm, Form _ChildForm, MagneticPosition _pos) 15. { 16. IsFirstPos = false; 17. step = 20; 18. MainForm = _MainForm; 19. ChildForm = _ChildForm; 20. Pos = _pos; 21. MainForm.LocationChanged += new EventHandler(MainForm_LocationChanged); 22. ChildForm.LocationChanged += new EventHandler(ChildForm_LocationChanged); 23. MainForm.SizeChanged += new EventHandler(MainForm_SizeChanged); 24. ChildForm.SizeChanged += new EventHandler(ChildForm_SizeChanged); 25. ChildForm.Load+=new EventHandler(ChildForm_Load); 26. MainForm.Load+=new EventHandler(MainForm_Load); 27. } 28. void ChildForm_Load(object sender, EventArgs e) 29. { 30. GetLocation(); 31. } 32. void MainForm_Load(object sender, EventArgs e) 33. { 34. GetLocation(); 35. } 36. void MainForm_LocationChanged(object sender, EventArgs e) 37. { 38. GetLocation(); 39. } 40. void MainForm_SizeChanged(object sender, EventArgs e) 41. { 42.

GetLocation(); 47. } 48. void GetLocation()//定位子窗体 49. { 50. if (ChildForm == null) 51. return; 52. if (Pos == MagneticPosition.Left) 53. LocationPt = new Point(MainForm.Left - ChildForm.Width, MainForm.Top); 54. else if (Pos == MagneticPosition.Top) 55. LocationPt = new Point(MainForm.Left, MainForm.Top - ChildForm.Height); 56. else if (Pos == MagneticPosition.Right) 57. LocationPt = new Point(MainForm.Right, MainForm.Top); 58. else if (Pos == MagneticPosition.Bottom) 59. LocationPt = new Point(MainForm.Left, MainForm.Bottom); 60. ChildForm.Location = LocationPt; 61. } 62. void ChildForm_LocationChanged(object sender, EventArgs e)//当窗体位置移动后 63. { 64. if (!IsFirstPos) 65. { 66. IsFirstPos = true; 67. return; 68. } 69. LocationDel del = new LocationDel(OnMove);//委托 70. MainForm.BeginInvoke(del);//调用 71. } 72. 73. void OnMove()//移动子窗体 74. { 75. if (ChildForm.Left > LocationPt.X) 76. if (ChildForm.Left - LocationPt.X > step) 77. ChildForm.Left -= step; 78. else 79. ChildForm.Left = LocationPt.X; 80. else if (ChildForm.Left < LocationPt.X) 81. if (ChildForm.Left - LocationPt.X < -step) 82. ChildForm.Left += step; 83. else 84. ChildForm.Left = LocationPt.X; 85. if (ChildForm.Top > LocationPt.Y) 86. if (ChildForm.Top - LocationPt.Y > step) 87. ChildForm.Top -= step; 88. else 89. ChildForm.Top = LocationPt.Y; 90. 91. else if (ChildForm.Top < LocationPt.Y) 92. if (ChildForm.Top - LocationPt.Y < -step) 93. ChildForm.Top += step; 94. else 95. ChildForm.Top = LocationPt.Y; 96. } 97. } 98. public enum MagneticPosition//磁性窗体的位置属性 99. { 100. Left = 0, 101. Top = 1, 102. Right = 2, 103. Bottom = 3 104. } 105. } 2.添加MainForm主窗体，打开Program.cs文件，修改为如下 ： [c-sharp] view plaincopy 1. static void Main() 2. { 3. Application.EnableVisualStyles(); 4. Application.SetCompatibleTextRenderingDefault(false); 5. Application.Run(new MainForm()); 6. } 3.添加ChildForm子窗体,不用写任何代码，当然实际中根据你自己的设计决定 4.在MainForm中添加四个button，分别设置text属性为:"左磁性" "上磁性" "右磁性" 下磁性" ，并分别添加按钮点击事件，具体代码如下： [c-sharp] view plaincopy 1. using System; 2. using System.Collections.Generic; 3. using System.ComponentModel; 4. using System.Data; 5. using System.Drawing; 6. using System.Linq; 7. using System.Text; 8. using System.Windows.Forms; 9. 10. namespace WindowsFormsApplication1 11. { 12. public partial class MainForm : Form 13. { 14. public MainForm() 15. { 16.

C#后台调用前台javascript的五种方法
C#后台调用前台javascript的五种方法 转自：http://blog.csdn.net/joetao/article/details/3383280 由于项目需要，用到其他项目组用VC开发的组件，在web后台代码无法访问这个组件，所以只好通过后台调用前台的javascript，从而操作这个组件。在网上找了找，发现有三种方法可以访问到前台代码： 第一种，OnClientClick (vs2003不支持这个方法) <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="client_click()" OnClick="Button1_Click" /> client_click() 就是javascript的一个方法。 第二种，Button1.Attributes.Add("onclick", "return Client_Click()"); “Client_Click() “是一个前台方法，可以替换成一般的脚本如：retrun confirm('确定删除吗？') 第三种，是我自认为最灵活的一种，ClientScript.RegisterStartupScript 例子：StringBuilder sb = new StringBuilder(); sb.Append("<script language='javascript'>"); sb.Append("Button2_onclick('" + serverPath + "')"); sb.Append("</script>"); ClientScript.RegisterStartupScript(this.GetType(), "LoadPicScript", sb.ToString()); 第四种. 用Response.Write方法写入脚本 比如在你单击按钮后，先操作数据库，完了后显示已经完成，可以在最后想调用的地方写上 Response.Write("<script type='text/javascript'>alert();</script>"); 这个方法有个缺陷就是不能调用脚本文件中的自定义的函数，只能调用内部函数，具体调用自定义的函数只能在Response.Write写上函数定义，比如Response.Write("<script type='text/javascript'>function myfun(){...}</script>"); 第五种 用ClientScript类动态添加脚本 用法如下：在想调用某个javascript脚本函数的地方添加代码，注意要保证MyFun已经在脚本文件中定义过了。 ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script>MyFun();</script>"); 这个方法比Response.Write更方便一些，可以直接调用脚本文件中的自定义函数。
C#桌面磁性窗体
转自：http://kb.cnblogs.com/a/1547320/ 看到千千静听的窗口可以在接近屏幕边缘时贴在边缘上觉得不错，自己也有这个需要，所以写了这个方法，测试了感觉还蛮不错的，哈哈~ 使用的时候只要在想应用的窗体的Form_Move(object sender,EventAges e)事件里面调用即可 ps：不过有时窗体可能会比较闪，这个可能是代码还有待改善，或者是在Form_Move事件里面来调用不大合适，反正功能是实现了，要是哪位有更好的方法，欢迎回复交流一下啊~ /// <summary> /// 磁性窗体函数 /// </summary> /// <param name="form">窗体控件(一般传this即可)</param> /// <param name="space">自定义的与屏幕边缘的距离</param> /// <param name="isWorkingArea">是否在屏幕工作区进行该操作(true表示不包括任务栏,false则包括整个屏幕的范围)</param> public void Form_Welt(Control form, int space, bool isWorkingArea) { //获取窗体的左上角的x,y坐标 int x = form.Location.X; int y = form.Location.Y; int sW = 0; int sH = 0; if (isWorkingArea) { //获取屏幕的工作区(不包括任务栏)的宽度和高度 sW = Screen.PrimaryScreen.WorkingArea.Width; sH = Screen.PrimaryScreen.WorkingArea.Height; } else { //获取整个屏幕(包括任务栏)的宽度和高度 sW = Screen.PrimaryScreen.Bounds.Width; sH = Screen.PrimaryScreen.Bounds.Height; } //如果窗体的左边缘和屏幕左边缘的距离在用户定义的范围内,则执行左贴边 if ((x <= space && x > 0) || (Math.Abs(x) <= space && x < 0)) //Math.Abs(x)是取绝对值 { form.Location = new Point(0, y); } //如果窗体的上边缘和屏幕上边缘的距离在用户定义的范围内,则执行上贴边 if ((y <= space && y > 0) || (Math.Abs(y) <= space && y < 0)) { form.Location = new Point(x, 0); } //窗体右边缘跟屏幕右边缘的距离 int rightW = sW - form.Right; //窗体下边缘跟屏幕下边缘的距离 int bottomW = sH - form.Bottom; //判断右边的情况 if ((rightW <= space && form.Right < sW) || (Math.Abs(rightW) <= space && rightW < 0)) { form.Location = new Point(sW - form.Width, y); } //判断下边的情况 if ((bottomW <= 10 && form.Bottom < sH) || (Math.Abs(bottomW) <= space && bottomW < 0)) { form.Location = new Point(x, sH - form.Height); } }

比如qq那样，拖到桌面边上，它会自动吸附在桌面边上，并且还会自动伸缩，（和windows的任务栏也类似） 两个窗口之间的吸附作用我也想了解，有谁知道怎么实现的是？？ 怎样建立磁性窗体(转贴于: ：《程序员》2002年第01期) 实现磁性窗体基本上分为两步，第一步是实现当两个窗体靠近到一定距离以内时实现窗体间的粘贴操作，第二步是一定窗体时，同时移动与它粘在一起的其它窗体。 实现窗体的粘贴 实现粘贴的难点在于什么时候进行这个操作，假设有两个窗体Form1和Form2，移动Form2向Form1靠近，当Form2与Form1的最近距离小于distance时粘贴在一起。显然，应该在移动Form2的过程中进行判断，问题是在程序的什么位置插入判断代码呢？ 合理的方法是利用系统产生的消息，但是利用什么消息呢？窗体在移动时会产生WM_WINDOWPOSCHANGING和WM_MOVING消息，移动结束后会产生WM_WINDOWPOSCHANGED和WM_MOVE消息。WM_WINDOWPOSCHANGING和WM_WINDOWPOSCHANGED消息的参数lParam是结构WINDOWPOS的指针，WINDOWPOS定义如下： typedef struct _WINDOWPOS { HWND hwnd; // 窗口句炳 HWND hwndInsertAfter; // 窗口的Z顺序 int x; // 窗口x坐标 int y; // 窗口的y坐标 int cx; // 窗口的宽度 int cy; // 窗口的高度 UINT flags; // 标志位，根据它设定窗口的位置 } WINDOWPOS; 可以看出，WM_WINDOWPOSCHANGED消息不仅仅在窗口移动时产生，而且在它的Z顺序发生变化时产生，包括窗口的显示和隐藏。所以我认为这个消息不是最佳选择。 WM_MOVING和WM_MOVE消息的参数lParam是一个RECT结构指针，与WM_WINDOWPOSCHANGED消息相比较为单纯，我采用的即是这个消息。 ----------------------------- 用 "磁性窗体 ",到google找,很多. 有了以上的东西,用C# 的unsafe code ,调用API,不难实现. ■■■■■ To teach a fish how to swim. ■■■■■
简单的磁性窗体源程序
最近在写一个小程序，顺便添加了一个磁性窗体功能。很简单，我却折腾了半天，现在把源代码奉献出来，供大家参考，不足之处希望指出。 //全局变量： private bool mouseDown = false; //鼠标是否按下 private Point mouseLocation; //鼠标位置 //鼠标移动事件 private void frmMain_MouseMove(object sender, MouseEventArgs e) ...{ bool move = true; //是否根据移动窗体 Point p1 = this.Location; //获得当前窗体坐标 if (mouseDown ==true) //检测鼠标是否按下 ...{ p1.Offset(e.Location.X - mouseLocation.X, e.Location.Y - mouseLocation.Y); //将p1按照鼠标移动偏移 if (Location.X <= 20 && e.Location.X - mouseLocation.X<=20) //判断当前窗体横坐标是否小于指定吸附距离，并且鼠标横位移是否小于此距离（注意：鼠标的位移一定要等于或大于指定距离，否则窗体会产生晃动） ...{ move = false; //此时鼠标移动不会移动窗体 if (!move) //检测此时是否由鼠标控制窗体 p1.X = 0; //将窗体吸附到边缘 } if (Location.Y <= 20 && e.Location.Y - mouseLocation.Y<=20) //检测纵坐标（其他同上） ...{ move = false; if (!move) p1.Y = 0; } this.Location = p1; //设置窗体位置为改变后的坐标 } } //鼠标按下事件 private void frmMain_MouseDown(object sender, MouseEventArgs e) ...{ if (e.Button == MouseButtons.Left) //判断是否按下鼠标左键 ...{ mouseDown = true; mouseLocation = e.Location; //获得此时的鼠标位置 } } //鼠标松开事件 private void frmMain_MouseUp(object sender, MouseEventArgs e) ...{ mouseDown = false; }
今天编程的时候，遇到一个问题：在同一个窗体区域加载两个不同的窗体，每次只显示一个子窗体并能够对这两个子窗体做切换。
今天编程的时候，遇到一个问题：在同一个窗体区域加载两个不同的窗体，每次只显示一个子窗体并能够对这两个子窗体做切换。 对于这个问题用panel控件是非常简单的，只要每次清空panel控件上的子窗体，然后加载另一个子窗体即可。代码如下所示： panel1.Clear(); // 清空的是当前panel上的子窗体 panel1.Add(subtabcontrol);//subtabcontrol是另一个子窗体
两个问题
两个问题 1、当切换两窗体的焦点时，子窗体的Location属性为什么会发生变化? 2、当最小化主窗体后，再恢复主窗体，子窗体却出不来了？ 主窗体的代码如下 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text;

//变量_x等于窗体x轴大小； _y = this.Location.Y; //变量_y等于窗体y轴大小； form.Owner = this;//设置owner form.Location = new Point(_x, _y); //初始化窗体的大小，相当于自定义； form.Show(); //磁性窗体的页面加载事件《上》；//show出窗体； }
