XSD.exe generate schema and classes from .webtest

stoneskin — Fri, 30 Mar 2012 02:53:43 GMT

Our company haven't Team Foundation Server, to do the integration web test, I plan to extend our existed AppMonitor application to run my .webtest file. the AppMon just simply call powershell script to send request to the webpage, if it can pick up the webtest, it can do more complicate testing.

To approach that final goal, the first thing is get the classes for the .webtest file deserialization.

below are my steps:
1. rename webtest1.webtest to webtest1.xml
2. in VS command line window, run "xsd webtest1.xml", and you will get webtest1.xsd
3. "xsd webtest1.xsd /classes", you class will be generated.

[MSTest Note2]create MS webtest file by fiddler2

stoneskin — Wed, 28 Mar 2012 22:50:54 GMT

Fiddler2 includes the ability to capture web traffic (including AJAX requests) for later playback with the Visual Studio Web Test product.

Simply run Fiddler and then interact with your Web Application. When you've finished using your web application, click File > Export Sessions > All Sessions. In the dialog, choose Visual Studio WebTest.

MSTest[Note1] webtest, don't forget enable Microsoft Web Test Addon of your IE

stoneskin — Wed, 28 Mar 2012 18:53:03 GMT

Tools--> Manage Add-ons--> Microsoft Corporation-->Microsoft Web Test Record
(and I noticed the Fiddler2 is not enable there either..)

After enable it, You can see the Web Test Recorder bar in the IE window's left.

easy mistakes in WCF DataContract

stoneskin — Fri, 16 Mar 2012 03:03:43 GMT

1. Defined [DataContract] but forget [DataMember] in DTO .You will got return DTO with all member be null or 0;
if all proprieties are datamember ,just need [Serializable],
but the fields name may be end with 'k__backingfield' if you generate class from service xml in client.
to fix this, either add [DataMember] to classes, or use the classes in client side also.

2. DataMember use Enum type which first item value not 0, and didn't initial the value. it will cause serialize/deserialize issue.
for example,

public enum SessionLOB //Line
Of Business { UnDefined = 1,
Auto = 4,
InstantRenter = 5,
StandardRenter = 32,
HomeOwner = 37
} ;

and with MyDTO has properties lob

public SessionLOB
lob { get; set; }

if the lob was not initialed and not be set a value, you will get null DTO, because it failed to deserialize 0 to SessionLOB

Fix the Jquery selectBox double init cause old selction not work issue

stoneskin — Fri, 23 Sep 2011 17:25:15 GMT

My Ajax call replace a dropdown box, then call
$('select').each(function () {
              $(this).selectBox();
            });

to update the jquery selectBox look and feel again.

but it caused the "setting is undefined: settings.menuTransition" error,

to fixed that need add

            $('select').each(function () {
                $(this).selectBox('destroy');

            });
Before the Ajax Call, so the next time you Initial it .the dropdown will be function..

JQuery Ajax and MVC3 Ajax

stoneskin — Fri, 16 Sep 2011 04:44:31 GMT

check the JQuery Ajax:

$.ajax({
type: "POST",
url: this.url,
data: form_data, beforeSend: function()
{ $('#ajaxDetails').addClass('progress'); }, error: function()
{ $('#status').text('Update failed—try again.').slideDown('slow');
}, success: function()
{ $('#status').text('Update successful!'); }, complete: function()
{ $('#ajaxDetails').removeClass('progress'); setTimeout(function()
{ $('#status').slideUp('slow'); }, 3000); } });

to get the from data:

var form_data = $("form").serialize(); var form_data_array = $("form").serializeArray();

a simple example:

$(document).ready(function()
{ $('#submit').click(function ()
{ var name = $('.uname').val(); var data = 'uname=' + name;
$.ajax({ type:"GET",
url:"welcome.php",
data: data, success: function (html)
{ $('#message').html(html);
} }); return false;
}); });





and MVC3 Ajax

@using (Ajax.BeginForm( 


"ActionName", 


"ControllerName", 


new AjaxOptions
{

 UpdateTargetId = "modal-dialog", 


OnFailure="searchFailed", 


OnBegin = "Dialog.Updating()", 


OnSuccess = "Dialog.Update({title:'Select
Friends'})" 


})) { 


… <input type="submit" value="Next" /> 


}

My First MVC3 remote validation

stoneskin — Sat, 10 Sep 2011 05:05:07 GMT

I created a new MVC project, and test the remote validation in the about page.

1)Controller Home:

 public ActionResult
ValidateTestName(string testName)
{ return Json(!testName.Equals("test"),
JsonRequestBehavior.AllowGet); }

2)Model:

using System.ComponentModel.DataAnnotations; using System.Web.Mvc; namespace MvcApplication1.Models
{ public class AboutModel
{ [Required] [Remote("ValidateTestName", "Home",
ErrorMessage = "this
Name already be used.")] public string TestName
{ get; set; } [Required] [Range(20, 44)] public int Age
{ get; set; } } }

3)View:
In _Layout.cshtml:

In About.cshtml

@model MvcApplication1.Models.AboutModel
@{
    ViewBag.Title = "About Us";
}

About

     Put content here.
     @using (Html.BeginForm())
     {
         @Html.EditorForModel();
                               
        "submit" value="Submit" />                      
     }

It is working perfect under FireFox 6:

but not working in my IE9 :(...
I have downloaded Jquery.Validation 1.8.1 try to fix this issue, but looks still unlucky.
(Jquery.Validation site : http://bassistance.de/jquery-plugins/jquery-plugin-validation/)

but this post in stack overflow said it tested in Chrome 10.0, IE9 and FireFox 4.0

how to input Trademark

stoneskin — Tue, 16 Aug 2011 16:35:37 GMT

http://fsymbols.com/computer/trademark/#windows

hold alt and input 0153 you will got ™
0174 you will got ®

to put/replace them in string:
str.Replace("®","\u00AE").Replace("&#174", "\u00AE").
Replace("", "\u2122")

some time you need use <sup>®</sup> in html

说说在MVC开发中,遇到的错误及解决方法

stoneskin — Tue, 19 Jul 2011 04:27:49 GMT

http://www.cnblogs.com/lori/archive/2011/07/18/2109817.html

前提:数据底层,使用的是MVC架构,对于数据表中的状态及相关字段,采用了枚举型进行对应

1 序列中不包含任何元素
解决：将Single()改为DefaultOrSingle()

2 序列包含一个以上的元素
解决：很多情况都是原始数据的问题

3 不能在已使用的实体上添加新实体
4 Duplicate key is already ,
3,4的解决为：用 base._db.ExecuteCommand()进行SQL语句的重写，

不要用LINQ自带的insert,就不会出现错误了

5 未将对象引用设置到对象的实例。值不能为空。参数名: source。
解决： this.iProduct_ProductFilesRepository.Insert(_entity.Product_ProductFile.Cast<Entity.IDataEntity> ().ToList());，当遇到将list实体类型换为接口list规范时，应该用.Cast<接口类型>().ToList()

6 查询参数不能为“System.Object”类型。
解决：这是因为在LINQ的ExecuteCommand不理解空值,当我们传递的参数为 null 时，就会出现这个问题，解决方法是，在为实体加string.empty这个空值属性

7 Incorrect syntax near '@p0'.
解决：查看我们的SQL代码，被编译成了什么，可能是多个括号之类的。如：delete from users where (userid={0}，这很明显是不对的，哈哈

8 不支持SQL的转化
   解决1，看看是否用了枚举类型，如果用了，应该先把IQueryable进行ToList，得到真正的数据后才能进行判断
   解决2,请看你的原始数据，很有可以是数据问题
   解决3,请看程序代码的关联表查询，很可能是它没有找出数据的问题

9 未将对象引用设置到对象的实例。
解决：查看数据库向数据实体赋值时，枚举类型的字段是否为null了，如果为null，就会出错

10 查询包含对不同数据上下文上所定义项的引用。
解决：查看底层工厂建立是否返回datacontext有问题，是否为空了。

11    枚举在LINQ中引发的异常：不支持SQL转换
    当枚举使用字符名称，没有数据，然它的数值存储在数据表中时，我们在返回数据时，必须在ToList()才行，否则就会出现这种问题
    例如：
     /// <summary>
     /// 以下是一个积分类型的枚举，一种类型对应数据表中同样类型的一个数值
     /// </summary>
   public enum PrestigeTypeCode
    {
           IAsk_Question,
            IAsk_Answer,
}

//表据表如下：
ID    描述        数值    枚举名称
1   提问           1    IAsk_Question
2   回答           1    IAsk_Answer

结论：当我们通过枚举去从数据库（SQLSERVer里）取数值时，必须要把结果集ToList()才行，如代码：
int value = new PrestigeTypesRepository().GetPrestigeTypes().ToList().Where(item => item.PrestigeTypeCode == prestigeTypeCode).Single().Amount;
如果，枚举的值，在枚举元素里读上，就不用去tolist()了

12 不能将 Null 值赋给类型为 System.Int32 (不可为 null 的值类型)的成员
解决:应该是数据的问题,Int类型的SQL表中出来了NULL值,或者是由于枚举类型转换失败的原因

Setup Windows Server 2008 to enable net.tcp for WCF

stoneskin — Wed, 25 May 2011 16:33:21 GMT

1. if net.tcp not enable on the server, you will see "The protocol 'net.tcp' is not supported." error message:

2. You need install and turn on the feature in Control panel\Programs and features:

3. then enable the protocols of your service:

4. set up the binding port:

5. done. it should be work, if not work, check those step again and the binding address in you web.config file.
I will post my service code and client code later.
