I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.
Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
' Get file name Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload) Dim UploadFileName As String = uploadAvatar.PostedFile.FileName If UploadFileName = "" Then ' There is no file selected args.IsValid = False Else Dim Extension As String = UploadFileName.Substring(UploadFileName.L
I need to make validation for Textbox to allow enter integer stated by 9 or 6 or 5 , and also maximum 8 digits , how to do that ?
I use in my ASP.NET MVC application repository pattern and I use in controller for example 3 models:
public class HomepageController : Controller
private IWebsitesRepository _repository_websites = new WebsitesRepository();
private IFirmRepository _repository_firm = new FirmRepository();
private IPhotosRepository _repository_photos = new PhotosRepository();
In WebsiteRepozitory, FirmRepository and PhotosRepository classes I have:
Database1Entities _entities = new Database1Entities();
So I have 3 connections to database ? Is it wrong ? How can I solve it ?
In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.
1. am I blind?
2. they decided it is too convenient to use and removed it?
3. they will "introduce" it in SP1?
What is going on? That one thing made me move back to VS 2008 web developer.
I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.
So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.
I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.
Here is my code:
<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="PerilTypeAndDetailsSection.VMEnterWhere" messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=220.127.116.11, Culture=neutral, PublicKeyToken=null" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris
I need to validate an XML through XSD. I am using XMLReader (with XmlReaderSettings and
Validation_EventHandler to do it). Depend on users preference, I would like to change the output message generated by Validation_EventHandler in french or english.
Any idea on how to perform this?
Windows Presentation Foundation has a rich data binding system that includes flexible support for business data validation. We take a look at implementing some complex data input validation scenarios that include customized data errors for users.

In this article, Paul Ballard shows how you can provide data binding support for your custom collections to enable sorting, searching, and editing in as simple a manner as possible. In addition, he shows how to make all of these features available in the Windows and Web Forms Designers, just like an ADO.NET DataSet.

Pattern recognition is an increasingly complex field. Every day technologies like handwriting recognition, spam filters, and search engines must identify ever more complicated patterns. One way these complex relationships can be represented is through the use of neural networks. Find out what neural networks can do for your pattern recognition and prediction tasks.

Web services use XML to communicate with each other. But sometimes the XML your service emits is not the same XML that another service is expecting. If you want to avoid the problems that this kind of situation can cause, you need to get good control over your XML serialization. Here author Chris Dix shows you exactly how to tackle this problem.
MSDN Magazine March 2005
As more organizations adopt XML-based Web Services, the need for message-level security has become evident. WS-Security, now supported in the Microsoft .NET Framework, addresses this need. Using the WS-Security framework, developers can implement channel sinks to intercept Remoting messages as they pass through the .NET Remoting infrastructure. The sink can read the message, change it, and pass it along. During this process, the message can be signed for added security. This article explains how to implement a Remoting channel sink that will modify the Remoting message by including a UserName token in the header, then sign the body using the token.

In an earlier article the authors showed how to build a custom WebMethods extension that provides XML Schema validation, a function that is lacking in ASP.NET. In the process they established a foundation for enforcing business rules during the deserialization of XML data. The technique, which is described in this article, uses declarative XPath assertions to test business rule compliance.In building this business rules validation engine, the authors integrate the validation descriptions into the WSDL file that is automatically generated by the WebMethod infrastructure. Finally, they demonstrate how to extend wsdl.exe, the tool that generates WebMethod proxy/server code from WSDL files, to make use of their extensions.
