How does it related to ASP.NET ?

Better you find on Online Forum of Flash and Flex. AFAIK : Flex Online help is fantastic.

If you need a fish bone diagram, gut a fish and grab a pencil. If you want a better answer, choose a forum that has something to do with your question.

hi all,
this is code behind:
[System.Web.Services.WebMethod, System.Web.Script.Services.ScriptMethod()]
public static DataView getAccounts()
{
try
{
string strCon = ConfigurationManager.ConnectionStrings["TFConnectionString"].ToString();
SqlDataSource db = new SqlDataSource();
db.ConnectionString = strCon;
db.SelectCommandType = SqlDataSourceCommandType.StoredProcedure;
db.SelectCommand = "getAccounts";
db.SelectParameters.Add("loginId", "K");
DataSourceSelectArguments args = new DataSourceSelectArguments();
DataView lst = (DataView)db.Select(DataSourceSelectArguments.Empty);
return lst;
}
catch (Exception ex)
{
return null;
}
}
and this is javascript:
function f1()
{
PageMethods.getAccounts(callSuccess, callFailuer);
}
function callSuccess(result)
{
alert(result[0]["account_nick"]);
}
function callFailuer()
{
alert('Fail');
}
in codebehind lst [DataView] shows records but on javascript its call failuer methode why?
i just want pass the data to javascript as a list.
thanks

DataView is not serialized. You need to pass XML or JSON serialized data objects through return.
Rather than going like this, I recommend to use a comma separated string to pass data to the javascript function.

I have a simple question about design patterns.
I need a quick design-pattern spot-check and thought a guru might have a minute.
I am not certain which design-patterns (if any) I am using or if I am using them correctly.
The short story...
I have a 1-to-1 mapping of DatabaseRow-to-Entity, where each Entity class just holds data.
I have a 1-to-1 mapping of EntityManager-to-Entity, where each EntityManager class just handles CRUD operations for its Entity.
If handling multiple Entity objects, they are collected into typed collections that are data-bindable.
I have a single DataContext that is used only by the EntityManager classes, and the DataContext knows how to connect to the database and run SQL-based CRUD operations
I think this uses TableModule + TableDataGateway + RowDataGateway + DataMapper.
What do you think?
The long story...
Here is what I do.
For each database table, I have one simple "Entity" class that maps directly to the table row. The Entity exposes each database column as a public property. The only logic in the Entity is validation logic, (such as IncomingValueForProperty1CannotExceedNCharacters, IncomingValueForProperty2CannotBeNull, etc), which simply throws an exception if there is a validation error. There is nothing else in the Entity class-- no SQL, no connection information, no database information, no SaveMethod, no UpdateMethod, nothing, etc. In short, the Entity just holds data. A sample name would be "AddressEntity".
Multiple Entity objects are collected in various says, such as a typed-collection, an array of objects, an EntitySet, or similar.
For each Entity, I have an "EntityManager" class. The sample name would be "AddressEntityManager". The EntityManager has methods like Create(AddressEntity targetEntity) and Retreive(object ID) and Update(AddressEntity targetEntity) and Delete(object ID). The Manager knows how to get data from the database based on an ID and return the data as a Entity. The Manager knows how to take an Entity passed to it and save the Entity to the database. Etc. The EntityManager uses the DataContext.
There is a single "DataContext" class that is used by all EntityManager classes. The DataContext class that knows how to connect to the database and conduct low-level CRUD, SQL-based operations.
This is very easy to implement and use. In particular, it is very clear to see who does what in terms of responsibility. The Entity holds data. EntityManager performs CRUD operations on an Entity. Need an Entity? Ask an EntityManager. Where is the data? Look in an Entity. Who does the work? The EntityManager. Who holds the data? The Entity. Need to do something to an Entity? Ask an EntityManager. It is transportable, in that it can be used on virtually any typical database-driven application. IMHO and IME.
A typical implementation is ASP.NET plus C# plus Linq-To-Sql (or Linq-To-Entities) plus SQL Server.
What pattern (or patterns) are expressed here?
I do have some ideas about which patterns are used. This way of working seems to have aspects of several patterns.
For "Domain Logic Patterns", it seems to have aspects of...
Table Module
http://www.martinfowler.com/eaaCatalog/tableModule.html[^]
For "Data Source Architectural Patterns", it seems to have aspects of...
Table Data Gateway
http://www.martinfowler.com/eaaCatalog/tableDataGateway.html[^]
Row Data Gateway
http://www.martinfowler.com/eaaCatalog/rowDataGateway.html[^]
Data Mapper
http://www.martinfowler.com/eaaCatalog/dataMapper.html[^]
However, I want to get your views on the matter, especially to help correct the design and improve it.
What do you think?
Please advise.
Thank you.

It's an interesting quesiton. First I'd ask, why do you want to know? What value will you receive in mapping patterns to your existing solution? I'm just curious, usually it's the other way around: you have a set of business requirements, then apply various patterns up front during the design process.

Regarding this...
>>>why do you want to know?
...I want to know because I want to correct the solution if necessary, and to make the solution better if possible, and to communicate the solution to others using the common terminology, and etc.
Regarding this...
>>>What value will you receive in mapping patterns to your existing solution?
...the value will be that the solution may be easier to understand, and the solution will be more documented given that it follows a pattern that has already been already well-documented, and the solution will be more fully tested given that it follows a pattern that has already been well-tested, and etc.
Thank you.

Great points!
Based on what I read, it sounds like the closest pattern is really Repository. Your "EntityManagers" seem to fit the bill quite nicely.
|
|
|
|

As per Fowler, your entity classes will be Data transfer objects[^].
Mark Kamoski wrote: Multiple Entity objects are collected in various says, such as a typed-collection, an array of objects, an EntitySet, or similar.
Each entity object is a different type. How can you make a single typed collection which are different types? Other than this, your design looks just good. I haven't read Fowlers EAA book and can't comment on the patterns you have provided. But the UML diagrams of those patterns shows, you have got the patterns correctly.

Regarding this...
>>>Each entity object is a different type. How can you make a single typed collection which are different types?
...that was actually pretty simple. At the implementation level, everything comes back as "IQueryable" and the underlying EntitySet is of the particular type needed. The call-site casts, which is not too much of a burden-- the caller must know what its asking for in a return or must live with a generic IQueryable object. It actually works quite well. Etc. Everything is pretty simple, as follows.
This is the interface that is implemented by each EntityManager...
<br />
...<br />
public interface IL2sEntityManager<br />
...<br />
IQueryable Retrieve();<br />
...<br />
This is a sample of what an EntityManager looks like...
This is the code being called...
<br />
...<br />
public partial class CategoryCodeManager : Team.Framework.Interfaces.BusinessLayer.BusinessEntities.IL2sEntityManager<br />
...<br />
public IQueryable Retrieve()<br />
...<br />
This is a sample call-site...
<br />
...<br />
protected void DataBindTest1()<br />
{<br />
BusinessLayer.BusinessManagers.CategoryCodeManager myManager = new BusinessLayer.BusinessManagers.CategoryCodeManager();<br />
<br />
IQueryable<BusinessLayer.BusinessEntities.CategoryCode> myEntitySet = (IQueryable<BusinessLayer.BusinessEntities.CategoryCode>)myManager.Retrieve();<br />
<br />
this.EntitySetGridView.DataSource = myEntitySet;<br />
<br />
this.EntitySetGridView.DataBind();<br />
}<br />
Etc.
I hope that answers your question.
Thank you.

If you are interested in a code sample, go to this link...
http://linq2sqleb.codeplex.com/SourceControl/PatchList.aspx[^]
...one can and you will file the file "Northwind01_T4Sample_200908141146.zip" is a fully-implemented, working, code sample (with PresentationLayer and BusinessLayer and etc) that shows one way to use T4 ToolBox to generate code from a database, using Linq-To-Sql-Entity-Base, the Repository design pattern (maybe), and a few other goodies.
HTH.
Thank you.

I moved a site onto a 2008 box after having it on a 2003 server box and did some testing only to find that the redirection on an error failed to go to the error.aspx page I had. I've been googling this for quite some time to no solution.
I looked for an IIS forum, but couldn't find one. I think the solution is in IIS, but I'm not sure.
Any help would be much appreciated.

wolfbinary wrote: redirection on an error failed to go to the error.aspx page
So, you are redirecting on Error Page from global.asax ? Can you show us the code for Application_Error Secction ?
I guess you are using Response.Redirect From Application_Error.
This is the Problem related with IIS 7 and Its integration mode. Which mode you are using ? Integrated or Classic ?
if Its Integrated mode and change to classic it may work.
Here[^] I found a good solution [ The summary as below ]
Analysis :
The problem is caused by changed behavior of IIS7 new integrated pipeline mode when calling Response.Redirect() in Application_Error. The default .net error page will be rendered before the actual redirection occurs due to error is detected.
Solution
1. Remove the module definition of ScriptModule under system.webServer/modules in web.config. e.g:
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
Remove Application_PreSendRequestHeader and Application_PreSendRequestContent event handlers from global.asax if they are not used.
2.Call Context.ClearError or Server.ClearError to clear the error before using Response.Redirect() in Application_Error.
Hope this will help you

I tried your above solution and you don't have to remove the config file part to get it to work. If you just clear the error and to the redirect all it well.
Thanks for the response though. It got me going in the right direction.

Hi..
I am using asp.net/c#.
I have used the following code for reading word document. But it reads only text data and not displaying the images in the word document.
string docname = dr["docname"].ToString();
string path= Server.MapPath("festival_doc");
string m = path + "//"+docname;
Word.ApplicationClass wordapp = new Word.ApplicationClass();
object file = m;
object nullobj = System.Reflection.Missing.Value;
Word.Document doc1 = wordapp.Documents.Open(ref file, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj);
TextBox1.Text = doc1.Content.Text;
doc1.Close(ref nullobj, ref nullobj, ref nullobj);
Can anyone solve the problem?
|
|
|
|
|
TextBox1.Text = doc1.Content.Text;
The above line is why it only reads text, it is all you're asking it to. Also, the text box you're assigning to can only handle text so if you try and set the value to any other property it probably won't compile.

Thanks for answering!
But I need to read all the data in the word document including images and display it in web page.
Please give me the solution.

Are you assigning the data into textbox? How can you expect a textbox to display images?

I have one page where I am allowing user to upload .xls file. I am storing these files on server in a folder. I have added <identity impersonate="true"> line in web.config.
After doing this above still its giving me following exception when I try to upload .xls file on the server.

Have you given read/write access to asp.net user on the folder where you are uploading files?

Your question makes no sense. If yuo get an error, tell us what it is. Post some code. Tell us what you're trying to do. This is useless. We cannot help you.
