  • How to query data from a password protected https website

    - by Addie
    I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp. I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query. System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv"); Here is the request sent to the site for authentication. I've angle bracketed the real userid and password. POST /pwdVal.asp HTTP/1.1 Accept: image/jpeg, application/x-ms-application, image/gif, application/xaml+xml, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */* User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; Tablet PC 2.0; OfficeLiveConnector.1.4; OfficeLivePatch.1.3; .NET4.0C; .NET4.0E) Content-Type: application/x-www-form-urlencoded Accept-Encoding: gzip, deflate Cookie: ASPSESSIONID<unsure if this data contained password info so removed>; ClientId=<username> Host: www3.emidas.com Content-Length: 36 Connection: Keep-Alive Cache-Control: no-cache Accept-Language: en-US client_id=<username>&password=<password>

  • What are the requirments for ISupportInitialize code to be serialized in InitializeComponent? .Net

    - by Jules
    I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net. What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control. Is that the minimum requirement?

  • How can I locate .NET Library property/function that return a particular type?

    - by Michael Bray
    Occasionally I will know that there is a .NET Framework function that returns a particular type of object, but I can't recall the property or function name. It would be really nice to be able to somehow scan the Framework or other DLL for functions that return a particular type of object. (For example, it would have helped when I asked this question, and I have a similar question again.) Can anyone suggest how I might do this?

  • 3-tier architecture v. 3-server architecture

    - by kawai
    I'm building a traditional .NET MVC site, so I've got a natural 3-tier software architecture setup (presentation in the form of Views, business layer in the controller, and data layer in the models and data access layer). When I've deployed such sites, it usually goes either on one server (where the web site and db live), or two servers (a web server and a separate db server). How does one go about a 3-server architecture (WEB, APP, and DB)? Would the web server just have the presentation (e.g. the physical View/aspx pages), the app server would hold the config file and bin folder, and the db server would remain as is? My question is essentially, can you simply move the /bin and all app logic onto a separate server from the presentation views? If so, how do you configure the servers to know where to look? If there's a good primer somewhere or someone can give me the lowdown, I'd be forever indebted.

  • NVelocity ASP.NET Examples

    - by Ben
    I'm looking to use NVelocity in my ASP.NET MVC application, not as a view engine, just for rendering some email templates. However, I cannot for the life of me get it to work. I have downloaded it from the castle project and followed the example at http://www.castleproject.org/others/nvelocity/usingit.html#step1 No matter what I try I don't seem to be able to load a template located in my site. The example suggests using the absolute path, which I have tried to no avail: Template t = engine.GetTemplate("/Templates/TestEmail.vm"); So please can someone give me two examples. One of loading a template located in the web site directory and secondly one parsing a string variable (as it is likely that my templates will be stored in a database). Many thanks Ben

  • Detect Browser Refresh vs. Form Submit in ASP.Net MVC 2

    - by Eric J.
    I have an ASP.Net questionnaire application that resubmits data to the same page, showing a different question each time. There are BACK and NEXT buttons to navigate between questions. I would like to detect when the form is submitted due to a browser refresh vs. one of the buttons being pressed. I came across a WebForms approach but don't know how to apply those principals in an MVC 2 application since page events aren't available (as far as I know... I'm pretty new to Microsoft's MVC model). How would one apply that principle to MVC 2? Is there a better way to detect refresh?

  • How do the httppost, httpput etc attributes in ASP.NET MVC 2 work?

    - by Tomas Lycken
    In ASP.NET MVC 2, a couple of new action filter attributes were introduced, as "shorthand" for attributes in ASP.NET MVC 1; for example, applying the HttpPostAttribute does the same thing as applying [AcceptVerbs(HttpVerbs.Post)] to an action method. In addition, with the more verbose syntax, it is possible to combine different methods, in order to allow for example both Post and Delete. Now I'm wondering: how do the new attributes work? If I apply both [HttpPost] and [HttpDelete], will ASP.NET MVC 2 allow both or require both (thus allowing nothing)?

  • I have VS2010RC and VS2008 installed - how can I run MVC 2 with both tools?

    - by DaveN59
    Hey all - I just downloaded the release version of MVC 2, pretty excited about that! Problem is, I can now create a MVC project in VS2010 but I don't seem to be able to do so in VS2008. We are using VS2010 RC for our main project. We need to use VS2008 for a new project so we can use the Connector/NET for MySQL, and I would love to be able to use MVC for this project. Does anybody know if this is possible? What am I missing, if anything? Thanks, Dave

  • Asp.Net MVC2 TekPub Starter Site methodology question

    - by Pino
    Ok I've just ran into this and I was only supposed to be checking my emails however I've ended up watching this (and not far off subscribing to TekPub). http://tekpub.com/production/starter Now these app is a great starting point, but it raises one issue for me and the development process I've been shown to follow (rightly or wrongly). There is no conversion from the LinqToSql object when passing data to the view. Are there any negitives to this? The main one I can see is with validation, does this cause issues when using MVC's built in validation as this is somthing we use extensivly. Because we are using the built in objects generated by LinqToSql how would one go about adding validation, like [Required(ErrorMessage="Name is Required")] public string Name {get;set;} Interested to understand the benifits of this methodology and any negitives that, should we take it on, experiance through the development process.

  • ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

    - by DennyDotNet
    I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

  • Is it possible to use the Spring MVC on JBoss App server?

    Hi. Is it possible to use Spring MVC on JBoss App server? If so, how? Used the Spring MVC with Tomcat Apache server, but now i have to move my project to a JBoss app server. But i'm getting an error, and i'm not sure why.

  • Debugging ASP.NET on a built-in web server suddenly stops

    - by Anton Gogolev
    I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

  • What is the difference between MVC model 1 and model 2?

    - by Alex Ciminian
    I've recently discovered that MVC is supposed to have two different flavors, model one and model two. I'm supposed to give a presentation on MVC1 and I was instructed that "it's not the web based version, that is refered to as MVC2". As the presentations are about design patterns in general, I doubt that this separation is related to Java (I found some info on Sun's site, but it seemed far off) or ASP. I have a pretty good understanding of what MVC is and I've used several (web) frameworks that enforce it, but this terminology is new to me. How is the web-based version different from other MVC (I'm guessing GUI) implementations? Does it have something to do with the stateless nature of HTTP? Thanks, Alex

  • How to Command Query Responsibility Segregation (CQRS) with ASP.NET MVC?

    - by Jeffrey
    I have been reading about Command Query Responsibility Segregation (CQRS). I sort of wonder how would this work with ASP.NET MVC? I get the idea of CQRS conceptually it sounds nice and sure does introduce some complexities (event and messaging pattern) compared to the "normal/common" approach . Also the idea of CQRS sort of against the use of ORM in some ways. I am trying to think how I could use this pattern in the coming projects so if anyone has experience in combining CQRS with ASP.NET MVC and NHibernate please give some concrete examples to help me better understand CQRS and use with ASP.NET MVC. Thanks!

  • Java Spring 3.0 MVC Annotation vs COC. Whats the preferred method in the Java community?

    - by Athens
    I am using Spring's MVC framework for an application I'm hosting on Google's App Engine. So far, my controllers are registered via the @Controller annotation; however, prior to getting into Spring, I evaluated ASP.net MVC 2 which requires no configuration and is based on convention. Is convention over configuration (COC) the current and preferred method in the Java community to implement MVC with Spring. Also, this may be a result of my limited knowledge so far but i noticed that i could only instantiate my Controllers the required constuctor injection if i use the COC method via the ControllerClassNameHandlerMapping. For instance the following controller bean config will fail if i use the defaultannotationhandlermapping. <bean id="c" class="com.domain.TestController"> <constructor-arg ref="service" /> </bean> <bean id="service" class="com.domain.Service" /> My com.domain.TestController controller works fine if i use ControllerClassNameHandlerMapping/COC but it results in an error when i use defaultannotationhandlermapping/Annotations.
