  • Unable to send email using 3rd party server ( IIS 7, Windows Server 2008, ASP.NET )

    - by Reed
    Hello All, I am using IIS 7 on Server 2008. I just tried migrating my app from an older platform - everything works fine, except the email feature. This is my config: < mailSettings > < smtp from="[email protected]" deliveryMethod="Network" > < network host="mail.xyz.com" port="25" userName="[email protected]" password="123" /> < / smtp > < /mailSettings > Whenever I need to send an email I use: SmtpClient smtp = new SmtpClient(); smtp.Send(email); The funny thing is I get absolutely no errors, however the email is never sent. The outbound firewall ruleset allows SMTP traffic. Any idea what I did wrong?

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • What is a .NET app domain?

    - by Luke
    In particular, what are the implications of running code in two different app domains? How is data normally passed across the app domain boundary? Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of AppDomains in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains

  • ASP.NET Dynamically filtering data

    - by Jasper
    For a project I'm working on, we're looking for a way to dynamically add filters to a page which then control the dataoutput in, for instance, a grid. We want to add the filters dynamically because we want the customer to be able to change which properties can be filtered and what filtertype (textbox, dropdown, colourpicker, etc.) should be used. The filter should work as follows: - The customer links a filter to a certain property and specifies the filtertype (for this example: dropdown). - A user control which contains all the filter loads all filters specified - The filters load all values of the specified property as options. The first time the page loads; this would be the values of all items. - Now the user selects a value from one of the filters; the page reloads - Only items which have the specified filter value are retrieved, the user may specify one or more filters at the same time. - Once a user drills down by filtering, only filtervalues of the retrieved items should be used in the other filters. I have the following problems: - When I create the filters runtime, events are lost because the controls get recreated each postback. - I could place the filters in PreInit which should solve this, but then determining which controls should be loaded becomes a problem since loading all environment vars isn't finished yet - I don't know a good way of returning all the filter values to a central point from which I can make a good query. - The query has to be dynamic. I'm using linq which I want to make dynamic so I don't have to select everything everytime. How to make a dynamic select query based on a string stored in the database? - I have to select items based on the filtervalues and then adjust the rest of the filters to the already made selection. That kind of messes up the whole regular databinding sequence. Any help in one of the above would be great! PS: One thing I thought about was passing along filter values in the postback which would have to be recognizable. That way the server could use them for selection and then create the filters and autoselect the previously selected filtervalues. I'm not quite sure how to acheive this though...

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!

  • Custom fine-grained claims based authorization system in ASP.NET MVC - wheres and hows

    - by BuzzBubba
    So, I'd like to implement my own custom authorization system in MVC2. If I'd have to create a global class, where do I instantiate it? Can HttpContext be extended with my own additions and where do I do that? Should I use Authorization filters for rights validation or ActionFilters or do it within an action? Can ActionFilter pass any data to the action itself? Previously (in WebForms) I was using a Session object where I would put a serialized object containing essential user data (account id and a list of roles and rights) and I'd extend my own Page class.

  • Testing the context in asp.net mvc

    - by user252160
    I got pretty experienced with testing controllers, my question here is though, aren't we supposed to test the data context as well, and how ? I mean, there are a lot of relationships and constraints coming from the DB that simply testing controllers does not cover. On the other hand, testing against the DB is not considered a good practice - what then ? Simply testing without db.SubmitChanges() or what ?

  • WS-Security using the ASMX file in ASP.NET 3.5

    - by Adam
    Basically I need to setup my ASMX file so that when I pull it up in a browser to display the WebMethod specification the Soap Header conforms to this format: <soap:Header> <wsse:Security> <wsse:UsernameToken wsu:Id='SecurityToken-securityToken'> <wsse:Username>Username</wsse:Username> <wsse:Password>Password</wsse:Password> <wsu:Created>Timestamp</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soap:Header> Back-story: I'm integrating with a client application that is already built (and owned by another company). Basically this client application already has their soap messages all set up from its past integrations with other companies. So we've opted to just build a web service using an ASMX file that matches the WSDL that they're already setup to consume. Is it possible to get WS-Security working on an ASMX file or is ASMX too simplistic and I have to upgrade to WFC (which I really don't want to do)?

  • .NET and Closing SQL Server connections

  • .NET Form_load priority

    - by mtranda
    So, the problem is such as this: I have a method that does stuff and updates a progress bar. If I call the method after the form is fully loaded (i.e.: by assigning it to a button on the form) everything works fine. The problem is that I need the method to start working as soon as the form loads, by itself, so I would place it in the Form_Load method. The problem is that even though I call Application.DoEvents() right before calling that method from within Form_Load, the form doesn't show up until the method has completed everything. As I said, if I let the form load first and call the method from another UI element for instance, everything works fine. Thanks in advance.
