这里只是主要写一些功能的实现
无边框窗体
首先设置窗体FormStyle属性 为none，设完就是什么都没有了，包括最大化最小化关闭都没了，这样你就可以自定义这些按钮了。但是无边框后会发现各种问题，比如无法拖动，无法缩放窗体，下面的代码将用于解决这一系列问题。
1、拖动和缩放无边框窗体：
View Code
const int WM_NCHITTEST = 0x0084; const int HT_LEFT = 10; const int HT_RIGHT = 11; const int HT_TOP = 12; const int HT_TOPLEFT = 13; const int HT_TOPRIGHT = 14; const int HT_BOTTOM = 15; const int HT_BOTTOMLEFT = 16; const int HT_BOTTOMRIGHT = 17; const int HT_CAPTION = 2; protected override void WndProc(ref Message Msg) { if (Msg.Msg == WM_NCHITTEST) { //获取鼠标位置 int nPosX = (Msg.LParam.ToInt32() & 65535); int nPosY = (Msg.LParam.ToInt32() >> 16); //右下角 if (nPosX >= this.Right - 6 && nPosY >= this.Bottom - 6) { Msg.Result = new IntPtr(HT_BOTTOMRIGHT); return; } //左上角 else if (nPosX <= this.Left + 6 && nPosY <= this.Top + 6) { Msg.Result = new IntPtr(HT_TOPLEFT); return; } //左下角 else if (nPosX <= this.Left + 6 && nPosY >= this.Bottom - 6) { Msg.Result = new IntPtr(HT_BOTTOMLEFT); return; } //右上角 else if (nPosX >= this.Right - 6 && nPosY <= this.Top + 6) { Msg.Result = new IntPtr(HT_TOPRIGHT); return; } else if (nPosX >= this.Right - 2) { Msg.Result = new IntPtr(HT_RIGHT); return; } else if (nPosY >= this.Bottom - 2) { Msg.Result = new IntPtr(HT_BOTTOM); return; } else if (nPosX <= this.Left + 2) { Msg.Result = new IntPtr(HT_LEFT); return; } else if (nPosY <= this.Top + 2) { Msg.Result = new IntPtr(HT_TOP); return; } else { Msg.Result = new IntPtr(HT_CAPTION); return; } } base.WndProc(ref Msg); }
2、圆弧边角及边框阴影效果：
View CodeView Code
public void SetWindowRegion() { System.Drawing.Drawing2D.GraphicsPath FormPath; FormPath = new System.Drawing.Drawing2D.GraphicsPath(); Rectangle rect = new Rectangle(0, 0, this.Width, this.Height); FormPath = GetRoundedRectPath(rect, 10); this.Region = new Region(FormPath); } private GraphicsPath GetRoundedRectPath(Rectangle rect, int radius) { int diameter = radius; Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter)); GraphicsPath path = new GraphicsPath(); // 左上角 path.AddArc(arcRect, 180, 90); // 右上角 arcRect.X = rect.Right - diameter; path.AddArc(arcRect, 270, 90); // 右下角 arcRect.Y = rect.Bottom - diameter; path.AddArc(arcRect, 0, 90); // 左下角 arcRect.X = rect.Left; path.AddArc(arcRect, 90, 90); path.CloseFigure();//闭合曲线 return path; } /// <summary> /// 当窗口改变时调动SetWindowsRegion函数改变窗口形象 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Frm_CYHBass_Resize(object sender, EventArgs e) { SetStyle(ControlStyles.SupportsTransparentBackColor, true); SetStyle(ControlStyles.AllPaintingInWmPaint, true); SetStyle(ControlStyles.UserPaint, true); SetStyle(ControlStyles.DoubleBuffer, true); this.Refresh(); SetWindowRegion(); }
3、窗体打开关闭动画：
View Code自定义关闭按钮
1、鼠标悬停图标变化：（先设置按钮的ImaleList对象并放入图标）
private void btn_Close_MouseHover(object sender, EventArgs e) { this.btn_Close.ImageIndex = 2; } private void btn_Close_MouseLeave(object sender, EventArgs e) { this.btn_Close.ImageIndex = 0; }
2、关闭事件：
private void btn_Close_Click(object sender, EventArgs e) { this.btn_Close.ImageIndex = 1; AniWindow a = new AniWindow(this.Handle, 7, 200, this);//从四周向中间隐藏 this.Close(); }
鼠标悬停窗体指定位置展开
1、只打开一个窗体：
if (Application.OpenForms["frm_mMenu"] == null) { //打开窗体 }
2、指定位置显示：
View Code
if (Application.OpenForms["frm_mMenu"] == null) { Frm_mMenu frm_mMenu = new Frm_mMenu(); frm_mMenu.Location = new Point(btn_Menu.Location.X + Frm_Main.pMainWin.Location.X - frm_mMenu.Width, btn_Menu.Location.Y + Frm_Main.pMainWin.Location.Y + btn_Menu.Height); frm_mMenu.Show(); }
3、换肤窗体从右上至左下展开：
Frm_mMenu 的Load事件(AniWindow 代码上面有)
private void Frm_mMenu_Load(object sender, EventArgs e) { AniWindow a = new AniWindow(this.Handle, 10, 200, this);//从左上角扩展效果 }
皮肤的实现
其实我的皮肤就是一张背景图片
1、皮肤切换：
View Code
/// <summary> /// 更换背景图片 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btn_Select_Pic_Click(object sender, EventArgs e) { openFileDialog1.Filter = "图片文件(*.jpg,*.gif,*.bmp,*.png)|*.jpg;*.gif;*.bmp;*.png"; if (this.openFileDialog1.ShowDialog() == DialogResult.OK) { /* *复制图片到根目录的skin文件夹命名为user_bg.jpg *将图片路径存储到配置文件 *待续.... */ //if (coverFile(openFileDialog1.FileName,System.Windows.Forms.Application.StartupPath+@"\skin\bg\0.jpg")) //{ selectBp[0] = new Bitmap(openFileDialog1.FileName); this.BackgroundImage = selectBp[0]; if (Application.OpenForms["frm_Main"] != null) { foreach (Form f in Application.OpenForms) { f.BackColor = this.BackColor; f.BackgroundImage = selectBp[0]; } skin.setBgConfig(0); } openFileDialog1.Dispose(); //} //else //{ // MessageBox.Show("设置失败!"); //} } }
2、配置保存：
这里我只是把图片覆盖到目标图片实现，于是经常报只读错误，因为读取用的是Image.From 但是它会锁定图片。
View Code3、根据背景图片颜色设置不同文本颜色：
这个比较有用啊，我后面做的很多项目中也用到过。
View Code
public Frm_mMenu() { InitializeComponent(); //this.BackgroundImage = Frm_Main.pMainWin.BackgroundImage; if (Frm_Main.pMainWin.BackgroundImage != null) { Bitmap bitmap = new Bitmap(Frm_Main.pMainWin.BackgroundImage); this.BackColor = bitmap.GetPixel(20, 15); } }
透明框提示
1、自定义控件？
不是，那时候还不懂自定义控件，直接用窗体代替了。关于窗体定位和单一显示和上面原理一样的。其中还糊里糊涂用到了GDI透明处理。后面才知道这就是传说中的不规则非矩形窗体的实现。
“控件”代码如下：
View Code
using System; using System.Drawing; using System.Windows.Forms; using System.Drawing.Drawing2D; using 搜壶浏览器.CYH_CL; namespace 搜壶浏览器.CYH_UI { public partial class Frm_Message : Form { public static bool IsClose; public string strMg = ""; public Frm_Message() { InitializeComponent(); } private void Frm_Message_Load(object sender, EventArgs e) { this.lbl_Message.Text = strMg; IsClose = false; timer_Close.Start(); Bitmap img = (Bitmap)this.BackgroundImage; GraphicsPath grapth = GetNoneTransparentRegion(img, 200); this.Region = new Region(grapth); AniWindow a = new AniWindow(this.Handle, 10, 200, this);//透明渐变显示 } /// <summary> /// 返回指定图片中的非透明区域； /// </summary> /// <param name="img">位图</param> /// <param name="alpha">alpha 小于等于该值的为透明</param> /// <returns></returns> public static GraphicsPath GetNoneTransparentRegion(Bitmap img, byte alpha) { int height = img.Height; int width = img.Width; int xStart, xEnd; GraphicsPath grpPath = new GraphicsPath(); for (int y = 0; y < height; y++) { //逐行扫描； for (int x = 0; x < width; x++) { //略过连续透明的部分； while (x < width && img.GetPixel(x, y).A <= alpha) { x++; } //不透明部分； xStart = x; while (x < width && img.GetPixel(x, y).A > alpha) { x++; } xEnd = x; if (img.GetPixel(x - 1, y).A > alpha) { grpPath.AddRectangle(new Rectangle(xStart, y, xEnd - xStart, 1)); } } } return grpPath; } private void Frm_Message_MouseLeave(object sender, EventArgs e) { //如果鼠标不在窗体上 if (!this.Bounds.Contains(Cursor.Position)) { this.Dispose(); this.Close(); } } private void timer_Close_Tick(object sender, EventArgs e) { if (IsClose) { timer_Close.Stop(); this.Dispose(); this.Close(); } } } }
2、调用“控件”方法：
View Code文档搜索功能实现
1、搜文档：
好吧，这个很简单，就是 加入了 搜索引擎 搜索规则，比如：搜word文档，百度框输入"关键字+fileType:doc" ，可以选择不同的搜索引擎。
2、指定网站：
同上类似 "搜索关键字+site:网站域名"
View Code
/// <summary> /// 高级搜索按钮 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btn_Search_Exp_Click(object sender, EventArgs e) { StringBuilder strB = new StringBuilder(); strB.Append(setting.getSearch_Engine()); if (rdBtn_DOC.Checked) { strB = strB.Replace("CYH", "CYH filetype:DOC"); } if (rdBtn_PPT.Checked) { strB = strB.Replace("CYH", "CYH filetype:PPT"); } if (rdnBtn_PDF.Checked) { strB = strB.Replace("CYH", "CYH filetype:PDF"); } if (txtBox_Site.Text.Contains(".")) { strB.Append(" site:" + txtBox_Site.Text.Trim()); } //WebBrowserArr[tabMain.SelectedIndex].GoSearch(); // C# Url传递中文 转义编码 //百度的编码 //System.Web.HttpUtility.UrlEncode( "中文 ", System.Text.UnicodeEncoding.GetEncoding( "GB2312 ")).ToUpper() //Google的编码 //System.Web.HttpUtility.UrlEncode( "中文 ") //得到值 //System.Web.HttpUtility.UrlDecode( "%BA%AB%B9%FA%D3%EF%D1%A7%CF%B0%D7%CA%C1%CF ", System.Text.UnicodeEncoding.GetEncoding( "GB2312 ")) NavToUrl(strB.Replace("CYH", cmbBox_SearchTxt.Text.Trim()).ToString()); //保存搜索历史 setting.saveSearchHis(this.cmbBox_SearchTxt.Text.Trim()); }
浏览器设置
1、启动页：
2、主页：
3、搜索引擎：
View CodeView Code
public void setHomepages(string value) { string strPath = System.Windows.Forms.Application.StartupPath + @"\Config\HomPgsConfig.txt"; FileInfo finfo = new FileInfo(strPath); if (finfo.Exists) { ///删除该文件 finfo.Delete(); } WriteFile(strPath, "HomePage", value, "*"); } public string getHomepages() { string strPath = System.Windows.Forms.Application.StartupPath + @"\Config\HomPgsConfig.txt"; string txt = ReadFile(strPath); if (txt.Length < 1) { return "about:blank"; } else { return txt.Split('*')[1].Trim().ToString(); } } public void setStartPage(string value) { string strPath = System.Windows.Forms.Application.StartupPath + @"\Config\StPgConfig.txt"; FileInfo finfo = new FileInfo(strPath); if (finfo.Exists) { ///删除该文件 finfo.Delete(); } WriteFile(strPath, "StartPage", value, "*"); } public string getStartPage() { string strPath = System.Windows.Forms.Application.StartupPath + @"\Config\StPgConfig.txt"; string txt = ReadFile(strPath); if (txt.Length < 1) { return "about:blank"; } else { return txt.Split('*')[1].Trim().ToString(); } }
当文件大于某值时删除
View Code那时候没学XML，网上例子也看不懂所以最终还是用文本+占位符方式保存配置的。
Internet选项
1、调用系统Internet选项：
private void btn_IE_Option_Click(object sender, EventArgs e) { //Frm_Main.pMainWin.WebBrowserArr[Frm_Main.pMainWin.TabSelectedIndex].ShowSaveAsDialog(); //调用IE的Internet选项 System.Diagnostics.Process p = new System.Diagnostics.Process(); p.StartInfo = new System.Diagnostics.ProcessStartInfo("rundll32.exe", "shell32.dll,Control_RunDLL inetcpl.cpl"); p.Start(); }
2、获取IE主页：
View Code浏览网页
1、Uri格式处理：
View Code2、历史记录：
第一次用上xml,而且是抄别人的，什么东西都不敢改。
View Code3、多标签：
这个。
//WebBrowser数组 public List<ExtendedWebBrowser> WebBrowserArr;
4、加载Logo：
这种写法显然不靠谱，不过那时候就是这么通过访问两次实现的。
View Code
/// <summary> /// 获取网站的标题图片 /// </summary> /// <param name="strUrl">网址</param> /// <returns></returns> private Image GetFavicon(string strUrl) { var uri = new Uri(strUrl); HttpWebRequest vHttpWebRequest = (HttpWebRequest)WebRequest.Create( @"http://" + uri.Host + @"/favicon.ico"); HttpWebResponse vHttpWebResponse = (HttpWebResponse)vHttpWebRequest.GetResponse(); Image vFavicon = Image.FromStream(vHttpWebResponse.GetResponseStream()); vHttpWebResponse.Close(); if (vFavicon != null) { return vFavicon; } else { return imgLstfavicon.Images[0]; } }
下载管理
1、下载实现：
那时候虽然刚接触Winform但是网上找个下载类还是很容易的。这个类还很强大的，不过我只用了最简单的功能。
View Code
using System; using System.IO; using System.Net; using System.Text; using System.Security; using System.Threading; using System.Collections.Specialized; namespace 搜壶浏览器.CYH_UI { /// <summary> /// 记录下载的字节位置 /// </summary> public class DownLoadState { private string _FileName; private string _AttachmentName; private int _Position; private string _RequestURL; private string _ResponseURL; private int _Length; private byte[] _Data; public string FileName { get { return _FileName; } } public int Position { get { return _Position; } } public int Length { get { return _Length; } } public string AttachmentName { get { return _AttachmentName; } } public string RequestURL { get { return _RequestURL; } } public string ResponseURL { get { return _ResponseURL; } } public byte[] Data { get { return _Data; } } internal DownLoadState(string RequestURL, string ResponseURL, string FileName, string AttachmentName, int Position, int Length, byte[] Data) { this._FileName = FileName; this._RequestURL = RequestURL; this._ResponseURL = ResponseURL; this._AttachmentName = AttachmentName; this._Position = Position; this._Data = Data; this._Length = Length; } internal DownLoadState(string RequestURL, string ResponseURL, string FileName, string AttachmentName, int Position, int Length, ThreadCallbackHandler tch) { this._RequestURL = RequestURL; this._ResponseURL = ResponseURL; this._FileName = FileName; this._AttachmentName = AttachmentName; this._Position = Position; this._Length = Length; this._ThreadCallback = tch; } internal DownLoadState(string RequestURL, string ResponseURL, string FileName, string AttachmentName, int Position, int Length) { this._RequestURL = RequestURL; this._ResponseURL = ResponseURL; this._FileName = FileName; this._AttachmentName = AttachmentName; this._Position = Position; this._Length = Length; } private ThreadCallbackHandler _ThreadCallback; public HttpWebClient httpWebClient { get { return this._hwc; } set { this._hwc = value; } } internal Thread thread { get { return _thread; } set { _thread = value; } } private HttpWebClient _hwc; private Thread _thread; // internal void StartDownloadFileChunk() { if (this._ThreadCallback != null) { this._ThreadCallback(this._RequestURL, this._FileName, this._Position, this._Length); this._hwc.OnThreadProcess(this._thread); } } } //委托代理线程的所执行的方法签名一致 public delegate void ThreadCallbackHandler(string S, string s, int I, int i); //异常处理动作 public enum ExceptionActions { Throw, CancelAll, Ignore, Retry } /// <summary> /// 包含 Exception 事件数据的类 /// </summary> public class ExceptionEventArgs : System.EventArgs { private System.Exception _Exception; private ExceptionActions _ExceptionAction; private DownLoadState _DownloadState; public DownLoadState DownloadState { get { return _DownloadState; } } public Exception Exception { get { return _Exception; } } public ExceptionActions ExceptionAction { get { return _ExceptionAction; } set { _ExceptionAction = value; } } internal ExceptionEventArgs(System.Exception e, DownLoadState DownloadState) { this._Exception = e; this._DownloadState = DownloadState; } } /// <summary> /// 包含 DownLoad 事件数据的类 /// </summary> public class DownLoadEventArgs : System.EventArgs { private DownLoadState _DownloadState; public DownLoadState DownloadState { get { return _DownloadState; } } public DownLoadEventArgs(DownLoadState DownloadState) { this._DownloadState = DownloadState; } } public class ThreadProcessEventArgs : System.EventArgs { private Thread _thread; public Thread thread { get { return this._thread; } } public ThreadProcessEventArgs(Thread thread) { this._thread = thread; } } /// <summary> /// 支持断点续传多线程下载的类 /// </summary> public class HttpWebClient { private static object _SyncLockObject = new object(); public delegate void DataReceiveEventHandler(HttpWebClient Sender, DownLoadEventArgs e); public event DataReceiveEventHandler DataReceive; //接收字节数据事件 public delegate void ExceptionEventHandler(HttpWebClient Sender, ExceptionEventArgs e); public event ExceptionEventHandler ExceptionOccurrs; //发生异常事件 public delegate void ThreadProcessEventHandler(HttpWebClient Sender, ThreadProcessEventArgs e); public event ThreadProcessEventHandler ThreadProcessEnd; //发生多线程处理完毕事件 private int _FileLength; //下载文件的总大小 public int FileLength { get { return _FileLength; } } /// <summary> /// 分块下载文件 /// </summary> /// <param name="Address">URL 地址</param> /// <param name="FileName">保存到本地的路径文件名</param> /// <param name="ChunksCount">块数,线程数</param> public void DownloadFile(string Address, string FileName, int ChunksCount) { int p = 0; // position int s = 0; // chunk size string a = null; HttpWebRequest hwrq; HttpWebResponse hwrp = null; try { hwrq = (HttpWebRequest)WebRequest.Create(this.GetUri(Address)); hwrp = (HttpWebResponse)hwrq.GetResponse(); long L = hwrp.ContentLength; hwrq.Credentials = this.m_credentials; L = ((L == -1) || (L > 0x7fffffff)) ?

2、监听文件：
我刚可代码就发现不对了，php好像被忽略了。其实最好一个通过min映射来判断，当然那时候肯定不懂。
View Code
/// <summary> /// 导航发生后发生 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void webMain_Navigated(object sender, WebBrowserNavigatedEventArgs e) { Url = this.WebBrowserArr[tabMain.SelectedIndex].Url.ToString(); this.cmbBoxUrl.Text = Url; if (!Url.EndsWith(".html") && !Url.EndsWith(".htm") && !Url.EndsWith(".jsp") && !Url.EndsWith(".aspx") && !Url.EndsWith(".asp") && !Url.EndsWith("/") && Url.Substring(Url.Length - 6, 5).Contains(".")) { Frm_Download_Dialog frm_Download_Dialog = new Frm_Download_Dialog(); frm_Download_Dialog.Show(); WebBrowserArr[tabMain.SelectedIndex].Stop();//停止导航 } }
关于页面
这个没什么好像是的仿照搜狗浏览器的，同样继承了无边框圆矩形窗体，然后加了一些背景图片什么的。
最后
虽然做出的这东西华而不实，代码也不怎么样，但我那时候真的是很努力的在做，而且最终也实现了所有功能，其实也学到了很多。
人之所以努力更多时候在于兴趣。
