  • How do I correctly model data in SQL-based databases that have some columns in common, but also have

    - by Brandon Weiss
    For instance, let's say I have a User model. Users have things like logins, passwords, e-mail addresses, avatars, etc. But there are two types of Users that will be using this site, let's say Parents and Businesses. I need to store some different information for the Parents (e.g. childrens' names, domestic partner, salaries, etc.) than for the Businesses (e.g. industry, number of employees, etc.), but also some of it is the same, like logins and passwords. How do I correctly structure this in a SQL-based database? Thanks!

  • The .NET ActiveX component with WPF content can't be loaded by non MFC app

    - by lonelyflyer
    I have a legacy delphi program and want to add some content implemented with WPF. So I encapsulate the WPF control with a .NET/ActiveX interop technology. That means something like: [ComRegisterFunction()] public static void RegisterClass(string key); [ComUnregisterFunction()] public static void UnregisterClass(string key); The activeX component is a WinForms User Control and the WPF materials are attached to an ElemenHost in this User Control. It works fine if the host app of this ActiveX is a MFC program even without /clr switch. But my legacy app is a delphi program, and it always throw a stackoverflow exception within the constructor of my WPF user control as the program be started. I have no clue, Google is no help. and it has puzzled me for days.

  • Error processing response in .net web service with WSE3 mutualCertificate10Security Assertion

    - by Maeloc
    I am securing a .net web service (framework 2.0) with WSE3 mutualCertificate10Security Assertion. When request are valid all is fine and the response is wellformed, but when the request is invalid (cause a invalid signature, failed check, or soapexception thrown), the web server isn't able to process the response to send to the client. The error in application event log is: An error occured processing an outgoing fault response. Details of the error causing the processing failure: System.InvalidOperationException: Send security filter on the server could not retrieve the operation protection requirements from the operation state. en Microsoft.Web.Services3.Security.SecureConversationServiceSendSecurityFilter.SecureMessage(SoapEnvelope envelope, Security security) en Microsoft.Web.Services3.Security.SendSecurityFilter.ProcessMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.Pipeline.ProcessOutputMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.WseProtocol.GetFilteredResponseEnvelope(SoapEnvelope outputEnvelope) All certificate permissions are OK (when request is OK the web service is able to sign the response). Error occurs only if a soapFault must be returned in the response. Any ideas?

  • How return 304 status with FileResult in ASP.NET MVC RC1

    - by Maysam
    As you may know we have got a new ActionResult called FileResult in RC1 version of ASP.NET MVC. Using that, your action methods can return image to browser dynamically. Something like this: public ActionResult DisplayPhoto(int id) { Photo photo = GetPhotoFromDatabase(id); return File(photo.Content, photo.ContentType); } In the HTML code, we can use something like this: <img src="http://mysite.com/controller/DisplayPhoto/657"> Since the image is returned dynamically, we need a way to cache the returned stream so that we don't need to read the image again from database. I guess we can do it with something like this, I'm not sure: Response.StatusCode = 304; This tells the browser that you already have the image in your cache. I just don't know what to return in my action method after setting StatusCode to 304. Should I return null or something?

  • Inherit from Type class of .Net

    - by Miguel Angelo
    Is there any point at all on inheriting from Type class in .Net? i.e. What could be the meaning of doing so? I am asking this because of this text in MSDN documentation: Notes to Inheritors When you inherit from Type, you must override the following members... list of members. MSDN doc for Type: http://msdn.microsoft.com/en-us/library/system.type.aspx ok, that is actually saying that anyone can inherit from Type... but they dont say why would you ever want to do that. Thanks!

  • asp.net free cms for library

    - by Andrew Florko
    We have library website written in classic ASP that allows to browse and search by multiple (50+) filter criterias (author, publication year, ISSN ... ). There are lots of security holes and we have only one developer who hardly maintain this ASP-site with some minor features for last 3 years. There are two common user groups - administrators (librarians) and students (5000+) who have books on hands and searches for them. We don't want to rewrite it from scratch, just to use standard free CMS (.net based) and migrate library data and user accounts with minimum effort. What CMS will you suggest? Thank you in advance.

The problem is I cannot add a web reference using Visual studio OR Disco.exe or Wsdl.exe - This webservice has been created on a java platform and for security reasons the only way to make a invoke the webservice is at runtime using SOAP protocol IN asp.net (VB). I I have created some code but cannot seem to send the soap object to the receiving web service. If I could get a solution with step by step instructions on how I can send a SOAP REQUEST.

  • .Net SvcUtil: attributes must be optional

    - by Michel van Engelen
    Hi, I'm trying to generate C# code classes with SvcUtil.exe instead of Xsd.exe. The latter is giving me some problems. Command line: SvcUtil.exe myschema.xsd /dconly /ser:XmlSerializer Several SvcUtil problems are described and solved here: http://blog.shutupandcode.net/?p=761 One problem I can't solve is this one: Error: Type 'DatafieldDescription' in namespace '' cannot be imported. Attributes must be optional and from namespace 'http://schemas.microsoft.com/2003/10/Seri alization/'. Either change the schema so that the types can map to data contract types or use ImportXmlType or use a different serializer. ' I changed <xs:attribute name="Order" use="required"> to <xs:attribute name="Order" use="optional"> and <xs:attribute name="Order"> But the error remains. Is it possible to use attributes, or do I have to delete them all (in that case, this excercition is over)?

  • DNS Lookup in ASP / ASP.Net

    - by Dave Forgac
    I have a Windows server that is intermittently losing the ability to lookup DNS information. I'm trying to get to the root cause of the problem but in the mean time I'd like to be able to monitor whether the server can perform lookups. Basically, it should attempt to lookup some common hostnames and the display 'Success' if the lookups are successful. I see lots of examples of doing this with third party components in ASP but I would prefer to be able to do this with a single ASP / ASP.Net script that would be portable and not require anything additional be installed.

  • asp.net FileUpload control problem: access to directory is denied

    - by citrus
    Hi, Im trying to use the fileupload control. Im using Visual Web Developer Express on my desktop. My web application is working fine except I cant use the fileUpload control. I get the following error: ERROR: Access to the path (My_Directory) is denied I searched and it appears to be a permissions problem. So I attempted to add the user ASPNET and give appropriate permissions to the directory, however, I was unable to add user "ASPNET". User "ASPNET" was not found. So then I followed the following directions to add user ASPNET via Control Panel Administration Computer management. So now I was able to add user ASPNET to the directory and give appropriate permissions but I still got the above error. http://p2p.wrox.com/net-web-services/5918-creating-aspnet-user.html Any ideas on why I cant access the directory?

  • ASP.NET Excel Export formatting question

    - by BWC
    Hey Guys, I've been banging my head on the wall over this issue for a couple days now and I need some help. I'm creating an excel file using ASP.net and everything is going just fine except one column has to be formatted as a decimal to 2 places but when it pulls into excel, excel automatically formats it as a whole number instead of keeping the decimal places. sw.Write(String.Format("{0:f}", CDbl(dr(14)).ToString("0.00"))) this produces "20.00" but when I open it in excel it's displayed as 20...if I select the whole column and format it as a number it gets displayed as 20.00 like it's supposed to but I don't want to have to do this (I can't do that) the file is supposed to be automatically picked up and imported into another system that needs the column to be a decimal. Any suggestions would be greatly appreciated.

  • ASP.NET Request.ServerVariables["SERVER_PORT_SECURE"] and proxy SSL by load balancer

    - by frankadelic
    We have some legacy ASP.NET code that detects if a request is secure, and redirects to the https version of the page if required. This code uses Request.ServerVariables["SERVER_PORT_SECURE"] to detect if SSL is needed. Our operations team has suggested doing proxy SSL at the load balancer (F5 Big-IP) instead of on the web servers (assume for the purposes of this question that this is a requirement). The consequence would be that all requests appear as HTTP to the web server. My question: how can we let the web servers known that the incoming connection was secure before it hit the load balancer? Can we continue to use Request.ServerVariables["SERVER_PORT_SECURE"]? Do you know of a load balancer config that will send headers so that no application code changes are needed?

  • Safe deployment of ASP.Net applications

    - by gatapia
    Hi All, I have an asp.net app that I want to deploy safely (with as little down time possible). I would love to do something like blue green deployment but without the need for a second web server. So, I know I can use load balancing, etc but I need a quick and cheap approach. I was thinking of doing something like: Setting up another website (copy of original) in IIS, currently I use host headers to direct traffic across sites). I could then view the new site locally until the site is totally online (due to NHibernate start up and various other high intensity tasks this takes a while). Once site 2 is totally started I would then change host headers around giving me a much much smaller down time. So my question is. Has anyone done anything like this? Will IIS restart my app pool or application when changing host headers (making this useless)? Any other options? Thanks for your help all. Guido

  • Adding Images to an ASP .Net Chart Control

    - by wali
    Hello all! I'm not sure if I titled the question correctly so it would be better if I explained what I'm trying to do. I am using the ASP .Net Chart Control to create a line chart showing numbers of trouble calls based on date. What I would like to do is implement a way of annotating the chart with data whereas if there was a spike in trouble calls a line, or asterisk, etc would direct the viewer to "read notes below for an explanation for why the numbers spiked here". From the samples for the chart control there is a way you can add a bitmap to the chart, however I don't see how that will be effective here because the explanations will come dynamically from a database. If anyone's done something like this or has some guidance I'd appreciate it. Thanks!
