Best Practice: General Asmx Data Loading Web-method Or Multi Web-methods
Apr 3, 2011which is better approach from performance point of view, is it better to use one web-service method to load data by passing Database Table name and keys or is it better to use separate method for each database table! knowing that i'm using .net asmx through ajax requests.it's obvious that one method is better from OO perspective since it have one function type 'data loading' but what about performance? does IIS affected by that or not? also is it better to make multi web-services 'asmx files' or just one!
View 3 RepliesWindows Azure General?
Nov 27, 2010does windows azure automatically scale up(by providing more instances), or I need to change this?
the extra small instance costs 0.05$/hour. According to Azure SLA I need to use at least 2 instances. This means 2 * $0.05*24*30=$72/month minimum. I can get on premise asp.net hosting for $5/month. Is there any offer I don't know about so I can build from the start on Azure architecture, or should I just switch to azure when I need more scaling and other servies that Azure offers because the difference in price is too high for me.
ADO.NET :: General / Better Way To Write A Report?
Mar 15, 2011i'm a new programmer, hope it's ok to ask this kind of general problem.
i don't know what it the general or better/best way to write a report?
it's a report of a financial system. lots of names, momey, amount, price, date, sum total... etc
like, [URL] (this is not mine, i just google "report")
i know i can use gridview/repeater... . use control and write sql command in it.
few days ago i heard some people will finish a report just in a store procudure! it looks better!
it doesn't include sql commands in .cs/.aspx file. i can separate sql command from c# codes! (finally!....)
so. question is, is this the best/better or most general way to write a report?
use store procedure? use sql user defined funcation? ....or ??

View 3 RepliesWeb Forms :: Page Validation General Approach?
Aug 19, 2010I have a web app that presents a list of statements pulled from the db to be ranked from "Never" to "Always" using a radioButtonList.
Some of the assessments have up to 100 statements, so I'm thinking that a ListView with paging and a RequiredFieldValidator for the radioButtonList would keep the presentation manageable.
I would like to submit the data after all of the pages are complete but I think that would require customization, or is my approach wrong?
Configuration :: Enterprise Library - Tracing To Logsource General Failed
Apr 19, 2010I have a web service that I developed on my local machine using the Enterprise Library for database access and exception logging. This all works fine on my machine but not on my server. I get the following error and i do not know why. Tracing to LogSource 'General' failed. Processing for other sources will continue. See summary information below for more information. Should this problem persist, stop the service and check the configuration file(s) for possible error(s) in the configuration of the categories and sinks. I do not see any errors in the configuration. I can get it to log to a flat file but not to the event log or an email it is to send. This is on a Windows Server 2008. Is there any special permissions I need to set? I hope this is the correct place to post a message such as this, if not let me know where to post it to.

View 3 RepliesWCF / ASMX :: Access/pass Parameters To A Web Service WITHOUT A (general) Form?
May 15, 2010I am a newbie to ASP.NET (but not to C#)I have a project I am developing that may seem unconventional at this point but it is a project that I hope to eventually expand and provide a new type of service on the internet. Currently the project makes use of an Excel spreadsheet that is generated by another application I wrote. Basically the spreadsheet is an index to a specific type of file that exists on a host computer and the files are directly linked from within the excel document. When the link is clicked it opens the file using the operating system default program which then processes the file (this takes some time).
This is fine and dandy but when I click on another file, the default program immediately stops processing one file and opens the latest submission and thus interrupting the previous job. To prevent this I am now writing a queuing application. Here is where ASP.NET comes in. I do not want the link to open the queuing application with the file to add into the queue as a parameter because that pops one or more nnoying/scary "you are opening an executable" dialogs and because I want to be able to access the queuing service from a remote computer, and possibily in the future over the web. Instead I am trying to use an ASP.NET service application that will accept the name of a file as a parameter, access the external queue class (defined in an external dll of which only one universal instance is allowed), and add the request to the queue. Whether or not the table is an excel table or on a web page, using a form in this instance is tedious, not only for me but for a user. I want the user to be able to simply click on an html link and have the file be queued without anything except maybe a confirmation page pop up saying that the file has been queued and it will take x amount of time before the file is finished processing.
My problem is I cannot for the life of me find a way to do this. I have searched the interenet for over a week now looking for a way to call a "WebMethod" using a link and I am getting the impression that it cannot be done. Even when I use a form and try to have the form pass a string (representing the file name) as its "action" it comes up with an application error saying that I am missing the parameter I am trying to pass. Here are some examples of what I have tried:Here an example method I would try to access:

The above table is just a sample table.
I have more than 1000 Order in my table. And for each Order there are at least 12 Order Detail is available in my Order Detail Table. It uses to take long time on loading the report for the first time. So, I thought to select Top 20 records from Order table. I have used the below query in crystal report command
Select Top 20 O.OrderNo, O.Product, O.Date, O.Qty,OD.Unit,OD.Rate from Order O
inner join Order Detail OD on O.OrderNo = OD.OrderNo
1. After execution of above query, I would like to know whether all the records from Order Detail Table will be checked during execution (OR) only matching Top 20 records of Order Table will be checked in Order Detail Table and executed?
2. How to use stored procedure in Crystal Report command?
3. What are the steps I need to take, to load Crystal report fast during first time page load?

View 2 RepliesDataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?
Oct 18, 2010I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?
AJAX :: Calling Webservices From Javascript: OnError Method, How To Identify The Method
Aug 26, 2010I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.

example:

en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)

Is there any way to know the webmethod that raised the error?
