  • GNU Smalltalk API?

    - by Zachary
    I have recently been learning Smalltalk, mainly by going through the tutorial at gnu.org. While it has been really helpful and I have learned a lot, I would really like an extensive smalltalk API where I could view all of the built in objects and which messages they can receive, and what they will do with those messages. The manual has a list of all of the built in objects, but doesn't really explain anything about them. Some are obvious, like an Array, but I still don't know what all the messages are an Array understands. There is a link to a 'class reference' here, which is generated by Smalltalk, but the link is broken. I was wondering if anyone knows of something like this hosted elsewhere, or could point me towards a similar resource.

  • Providing or Filtering assemblies when registering areas for an ASP.NET MVC 2.0 application

    - by HackedByChinese
    I have a large application that currently exists as a hybrid of WebForms and MVC 2.0. Startup of my application is dreadful, and the culprit is primarily because of the AreaRegistration.RegisterAllAreas call. More specifically, that it is using the System.Web. Compilation.BuildManager.GetReferencedAssemblies to enumerate all types in assemblies directly referenced by the application and test them to see if they derive from AreaRegistration. Unfortunately, I have a number of third-party assemblies that happen to be quite extensive, so this initial load can be pretty bad. I'd have much better results if I could tell it which assemblies to look for AreaRegistrations, or even register areas manually for the time being. I can gather up all the internals of AreaRegistration to create and invoke the registration, but I'm just curious if others have had and worked around this issue.

  • ASP.Net MVC: "Random" URLs getting generated by URL.Action

    - by Daniel Magliola
    I have 2 very similar routes, just because i'm trying to generate two different URLs for the same resource (same Controller/Action), and both are very similar. These are the routes definitions: routes.MapRoute("Post2.Mp3", "sites/{siteSlug}/post/{brand}/aconstant-{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[^(aconstant\-)][A-Za-z0-9-_]+", brand = @"[A-Za-z0-9-_]+" }); routes.MapRoute("Post.Mp3", "sites/{siteSlug}/post/{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[A-Za-z0-9-_]+" }); "brand" is going to be my site name, which is the same as "aconstant" in those routes. Now, if I try this: Url.Action("ShowMp3", "Posts", new { siteSlug = post.Site.Slug, slug = post.Slug, origin = "origfeedwithaudio", brand = "aconstant" }) sometimes I get the URL I expect: /sites/site-Name/post/aconstant/aconstant-post-Name.mp3 but sometimes, I get this: /sites/site-Name/post/post-Name.mp3?brand=aconstant By sometimes, I mean that different sets of "slugs" give me one or the other. I haven't seen the same set of slugs give me different URLs. I haven't found any reasonable rule for when i'm getting one or the other, it seems random. What is going on here? How can I be getting different URLs based on esentially the same arguments? Thanks! Daniel

  • Using a profile property of type List in .NET Membership

    - by hancock
    Hi, I'm working on a C# Webservice that needs to provide authentication as well as roles and profile management. I need each profile to have a property of type List. The profile section in the web.config looks like this: <profile defaultProvider="MyProfileProvider" enabled="true"> <providers> <remove name="MyProfileProvider"/> <add connectionStringName="MySqlServer" applicationName="MyApp" name="MyProfileProvider" type="System.Web.Profile.SqlProfileProvider" /> </providers> <properties> <add name="Websites" type="System.Collections.Generic.List&lt;String&gt;" serializeAs="Binary"/> </properties> </profile> However, when I start the webservice and try to access that property it returns the following error: System.Configuration.ConfigurationErrorsException: Attempting to load this property's type resulted in the following error: Could not load type 'System.Collections.Generic.List<String>'. (C:\Projects\MyProject\web.config line 58) --- System.Web.HttpException: Could not load type 'System.Collections.Generic.List<String>'. Is there a way to use a generic collection for this purpose?

  • Problem with persisting interface collection at design time in winforms, .net

    - by Jules
    The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • ASP.net - First build fails with 'Unknown server tag'

    - by Sophia
    I have multiple custom controls used on a ASPX (and C#) page registered from within the page rather than in Web.Config. On the first build (or rebuild), build fails with error messages for wherever I've used the custom controls. Subsequent builds are successful. The error message: Unknown server tag 'prefix:ExampleControl'. What might cause this, and how can I fix it? Register syntax: <%@ Register Src="ControlsFolder/ExampleControl.ascx" TagName="ExampleControl" TagPrefix="prefix" %> <!-- etc --> Usage syntax: <prefix:ExampleControl runat="server" ID="ExampleControl1" /> <!-- etc -->

  • ASP .NET MVC; return HTML along with JavaScript

    - by effkay
    I have a partial view which renders a table. On page load, I am using JQuery to perform Zebra Stripping on it. Whenever ajax refreshes the table, DOM elements are updated, but since JQuery code to do the Zebra Stripping is not executed; table looks ugly. I have tried adding Javascript in my partial view if( Request.IsAjaxRequest() ) return PartialView( "AdministrationGrid", Users ); but javascript is not executed. I guess the only way to execute the Javascript as reply is to do: return JavaScript( "alert( '' )" ); Anyone with an idea how can I achieve this? I thought about JQuery Live, but it is used to bind itself to events.

  • Winforms / .Net - dynamically creating install .exe or script

    - by Serexx
    Hello -- Does anyone know how I can Dynamically create an installation package that installs files into a folder that is determined at installation-runtime, not by the user, but by obtaining the UserAppDataPath for that specific user on that specific PC. By dynamically I mean that I must create the installation package programatically as part of another process. Any help ideas greatly appreciated!

  • setUserCredentials from Google data api is stuck

    - by yogsma
    Well, since I am facing some issues with OAuth implementation, I decided to go back to normal method where users will input their login id and password and I will use them in my code to validate their google account to fetch calendar information. So when user enters login id and password, the page is getting stuck. When I check the code, setUserCredentials is the method where it is getting stuck. But when I enter my login id and password and debug on development site, it works fine. There is no problem when I debug. And importantly , the problem appears for first time only, once I debug the code and next time I try it without breakpoint, it works fine. Does anyone know why setUserCredentials takes time or any way I can track why it is taking so time? I have asked the same question on Google data api forum, but nobody answered it.

  • Performance problem with System.Net.Mail

    - by Saif Khan
    I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

  • ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

    - by Dr. Zim
    In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

  • Multidimensional arrays in VB.NET 2010

    - by matt_t
    Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.

  • ASP.net MVC 2 and MonoDevelop 2.2

    - by rifferte
    Is it possible to utilize MVC 2 from MonoDevelop 2.2 (using Mono 2.4)? If so - is it as simple as grabbing a reference to the new System.Web.Mvc or is there something else to consider? I realize that any templating support in MonoDevelop may not be 100% there since it was built to utilize MVC v1 (at least as of MonoDevelop 2.2). If anyone can add any other tips or tricks that would help as well.

  • ASP.NET MVC2 - Resolve Parameter Attribute in Model Binder

    - by Nathan Taylor
    Given an action like: public ActionResult DoStuff([CustomAttribute("foo")]string value) { // ... } Is there any way to resolve the instance of value's CustomAttribute within a ModelBinder? I was looking at the MVC sources and chances are I'm just doing it wrong, but when I tried to replicate their code which retrieves the BindAttribute for a complex model, calling GetAttributes() did not return the attribute I am looking for. DefaultModelBinder GetTypeDescriptor(controllerContext, bindingContext).GetAttributes();

I refresh these partial view by ajax. So I need to pass data among view and its partial views. The best way would be if I could pass data without using Temp data dictionary. Anybody know a good article about this? l.

  • Strange WndProc bug in .Net. VB.Net more specifically.

    - by Jules
    ETA: I use visual studio 2008 express edition. If I override WndProc and mess up somehow, I'll usually backtrack by commenting out code until it works again. The strange thing with WndProc though is you can strip it down to: Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) MyBase.WndProc((m)) End Sub and it still throws the error. I have to remove the code and retype it in to reset the error. Anyone else experienced this?

  • Realtime progress of AJAX call (asp.net)

    - by Dynde
    Hi... I'm trying to make a progress bar that updates the user on the progress of the AJAX call. My immediate thinking was that I need an AJAX call to start a thread on the server, allowing the starting AJAX call to finish, and allowing the thread to send updates back to the user. For the purpose of simplicity, disregard the actual progress bar functionality (I was thinking of implementing one of those JS bars, with fancy colors and effects ;), but if I can get an update from the thread, then updating a simple JS progress bar becomes trivial ;) ) I just need a few pointers on how to accomplish this, if anyone could oblige me? ;)
