2. 打开 .aspx 文件是, 只有HTML编辑视图,没有视图切换选项

在命令行中运行：devenv /ResetSkipPkgs 即可解决该问题.

     1. 重定义了系统的触发事件名称作为自定义函数名如：  onclick / onsubmit ...  都是系统保留的事件名称，不允许作为重定义函数名称。

     2. 出现死循环，都提示：Stack overflow at line: 0 , 如：在图片对象定义了 onerror 事件的循环处理、

          <img src="http://www.cnblogs.com/images/a.gif" onerror="this.src='/image/block.gif'" />

          这里并不是说 /images/a.gif 不存在， 可能是由于网络原因造成， 这时会执行 onerror 事件,  调用 /images/block.gif 去做当前图片的路径， 但如果当前 /image/block.gif 这个图片文件不存在， 再或者由于网络原因， '/image/block.gif' 下载又出现错误时， 就出现了死循环。

          所以在处理 onerror 事件时，要考虑是否是出现这样的问题。

     ” Stack overflow at line: 0 “ 该错误不是一直出现，是有时会出现， 是网络不正常导致死循环引起的， 查了好半天， 最后才找到这个原因，做下记号吧， 给有需要的人。

现在有以下的接口参数就太方便了. 可在自己定义状态的图片信息等.

http://messenger.services.live.com/users/youliveid@msn.com/presence/?cb=showpresence

{
    "icon": {
        "url": "http://www.wlmessenger.net/static/img/presence/Online.gif", "height": 16, "width": 16
    }, "statusText": "Online", "status": "Online", "displayName": "s.sams", "id": "youliveid@msn.com"
}

再结合 Newtonsoft.Json 完全实现自定义操作.

http://www.codeplex.com/Json

Code(该摘自:Json.net/Newtonsoft 3.0 新特性JObject/Linq to Json )
static void Main(string[] args)
{
string str = "{title:123,body:456,list:{title:'这是一个标题',body:'what'}}";
JObject o = JObject.Parse(str);
Console.WriteLine(o["title"]);
Console.WriteLine(o["body"]);
Console.WriteLine(o["list"]["title"]);
Console.WriteLine(o["list"]["body"]);
Console.ReadKey();
}

BIND version 9 is a major rewrite of nearly all aspects of the underlying BIND architecture.

BIND 9.5 is the current release of BIND. It is supported, and bug fixes and security fixes will be made available as minor releases (9.5.y).

Some of the important features of BIND 9 are:

• DNS Security
  • DNSSEC (signed zones)
  • TSIG (signed DNS requests)
• IP version 6
  • Answers DNS queries on IPv6 sockets
  • IPv6 resource records (AAAA, DNAME, etc.)
  • Experimental IPv6 Resolver Library
• DNS Protocol Enhancements
  • IXFR, DDNS, Notify, EDNS0
  • Improved standards conformance
• Views
  • One server process can provide multiple "views" of the DNS namespace, e.g. an "inside" view to certain clients, and an "outside" view to others.
• Multiprocessor Support
• Improved Portability Architecture

BIND version 9 development has been underwritten by the following organizations:

Sun Microsystems, Inc.
Hewlett Packard
Compaq Computer Corporation
IBM
Process Software Corporation
Silicon Graphics, Inc.
Network Associates, Inc.
U.S. Defense Information Systems Agency
USENIX Association
Stichting NLNet - NLNet Foundation
Nominum, Inc.

实现功能:

     1. Tooltip

     2. Validate 表单验证

     可分开独立使用    

     您可以不写一行代码, 只需设置验证规则即可

     其实园子已经存在不少基于jQuery的验证插件, 如: http://www.cnblogs.com/wzmaodong/archive/2008/05/21/1203962.html

但感觉使用起来过于麻烦, 要实现在大堆表单的验证, javascript 代码一大堆. 所以这里的设计原则就是使用便捷, 易维护, 同时适应性大.

在验证中使用了自定义正则表达式, 这样用起来就非常方便了.  先看下最后的效果图

     1. 即时表单验证和提示

     2.  提交表单时验证

     下面看下我们如何在 asp.net 中实现便捷的提示功能和表单验证功能

Code
<li>
    <label>航班号</label>
    <asp:TextBox ID="_flightno" runat="server" reg="\w{2}\d{4}" tip="设置航班号(大写)" toupper="true" />
</li>
<li>
    <label>航司(2字代码)</label>
    <asp:TextBox ID="_airline" runat="server" reg="\w{2}" toupper="true" /> (注意大写)
</li>
<li>
    <label>起飞时间</label>
    <asp:TextBox ID="_beingtime" runat="server" reg="\d{4}" tip="设置起飞时间 格式: hhmm" /> (格式: hhmm)
</li>

 以上的实现是不是很方便, 不用写大堆的 javascript 逻辑代码便可轻松实现验证和提示功能

通过调用 $(document).ready(function() {jQuery('input[tip],input[reg]').tooltip({onsubmit: true})}); 便完成数据的验证和提示功能. (该调用已集成在tooltip.js中)

onsubmit: true 这里设置是否触发 onsubmit 的提交验证事件.

再看看 CSS 的实现

.tooltipinputerr
{}{
    padding: 2px 0 2px 18px;
    border: solid 1px red;
    background: #ffff99 url(/images/exclamation.png) no-repeat 2px center;
    }
    
.tooltipinputok
{}{
    padding: 2px 0 2px 18px;
    border: solid 1px green;
    background: url(/images/accept.png) no-repeat 2px center;
    }
    
.tooltipshowpanel
{}{
    z-index: auto;
    display: none;
    position:absolute;
    width: 276px;
    height: 35px;
    overflow: hidden;
    text-indent: 5px;
    line-height: 40px;
    font-size: 12px;
    font-family: Arial;
    background: url(/images/tooltop.gif) no-repeat left top;
    opacity:0.9;
    filter: alpha(opacity=90);
    }

 使用方法:

     一.

Download jQuery

Download jQuery 1.2.6 (16kb, Minified and Gzipped) Great for production use.

Download jQuery 1.2.6 (97kb, Uncompressed) Great for testing, learning and development.

Download jQuery 1.2.6 (30kb, Packed) For those that can't Gzip their JavaScript.

  二. 加入以上样式和引用tooltip.js文件

Tooltip.pack.js	1KB	0	2008/8/6 22:41:16
Tooltip.mini.js	1KB	0	2008/8/6 22:41:11

What is jGrow?

jGrow is a jQuery plug-in that makes the textarea adjust its size according to the length of the text.

It works smoothly with jQuery 1.2.x. It was tested on IE6/7, Firefox 2.0.x and Opera 9.x, and no bug was spotted yet.

非常好一个jQuery插件, 但原版不支持 Ctrl + V 的键盘操作事件, 直接代码.

 /* 原版代码.
 * jGrow 0.2
 * 08.02.2008
 * 0.2 release: 04.03.2008
 */
 
 (function($) {

  $.fn.jGrow = function(options) {

   var opts = $.extend({}, $.fn.jGrow.defaults, options);

   return this.each(function() {

    $(this).css({ overflow: "hidden" }).bind("keypress", function() {

     $this = $(this);

     var o = $.meta ? $.extend({}, opts, $this.data()) : opts;

     if(o.rows == 0 && (this.scrollHeight > this.clientHeight)) {
      
      this.rows += 1;
      
     } else if((this.rows <= o.rows) && (this.scrollHeight > this.clientHeight)) {

      this.rows += 1;

     } else if(o.rows != 0 && this.rows > o.rows) {

      $this.css({ overflow: "auto" });

     }

     $this.html();

    });

   });

  }

  $.fn.jGrow.defaults = { rows: 0 };

 })(jQuery);

以下为改进后的代码, 支持 Ctrl+V 键盘事件操作

 /*

   return this.each(function() {

    $(this).css({ overflow: "hidden" }).bind("keypress", function() {
    
        $this = $(this);

     if(o.rows == 0 && (this.scrollHeight > this.clientHeight)) {

     } else if((this.rows <= o.rows) && (this.scrollHeight > this.clientHeight)) {

      this.rows += 1;

     } else if(o.rows != 0 && this.rows > o.rows) {

      $this.css({ overflow: "auto" });

     }

     $this.html();

    }).bind("keydown",function(event){
    
        if(event.keyCode == 17) isCtrl = true;
          
    }).bind("keyup",function(event){

        if(isCtrl && event.keyCode == 86)
        {
         var o = $.meta ? $.extend({}, opts, $this.data()) : opts;
            var getCL = this.value.split('\n').length

             $(this).css({ overflow: "auto" });
         }
         isCtrl = false;
     }
    });

   });

  }

  $.fn.jGrow.defaults = { rows: 0 };
