  • Inserting Parameters, C#, T-Sql

    - by jpavlov
    I am trying to insert a parameter through an aspx page via text box. I set my parameters up, but evertime I executenonquery, the @Username shows up in the database instead of the actual value. Below is my code. Can anyone shed a little insight? SqlParameter @UserName = new SqlParameter("@UserName", System.Data.SqlDbType.VarChar); @UserName.Direction = ParameterDirection.Input; @UserName.Value = txtUserName.Text; cmd.Parameters.Add(@UserName);

  • asp.net mvc create a c# class in an ascx file for design purposes

    - by Julian
    Hi, I am developing a web application using asp.net mvc. I have come across the need to Temporarily create a class in the ascx/aspx file. This class will replace the Model during the development of the page. It will also hold some test data for the user to have the chance to see some results. Once we are happy with the layout on the screen, I will inherit the correct Model class through the Control tag. Can you please advise if this is possible and how to do it? This does not work: <% class Modelo { public Guid Guid { get; set; } public string Name { get; set; } } %> Thanks in advance, Be happy - Julian

  • What's the convention for extending Linq with set based helper operations

    - by Luke Rohde
    Hi All I might be vaguing out here but I'm looking for a nice place to put set based helper operations in linq so I can do things like; db.Selections.ClearTemporary() which does something like db.DeleteAllOnSubmit(db.Selections.Where(s => s.Temporary)) Since I can figure out how to extend Table<Selection> the best I can do is create a static method in partial class of Selection (similar to Ruby) but I have to pass in the datacontext like; Selection.ClearTemporary(MyDataContext) This kind of sucks because I have two conventions for doing set based operations and I have to pass the data context to the static class. I've seen other people recommending piling helper methods into a partial of the datacontext like; myDataContext.ClearTemporarySelections(); But I feel this makes the dc a dumping ground for in-cohesive operations. Surely I'm missing something. I hope so. What's the convention? TIA

  • subsonic in visual studio design host

    - by csizo
    Hi, I'm facing currently a problem regarding Subsonic configuration. What I want to achieve is using subsonic data access in a System.Web.UI.Design.ControlDesigner class. This class is hosted in Visual Studio Environment and enables design time operations on the attached System.Web.UI.WebControls.Control. The only problem is SubSonic seems always looking for SubSonicSection in the application configuration regardless passing connection string to it. The relevant code snippet: using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(new SqlDataProvider(), ConnectionString)) { Table1 _table1 = new Select().From<..().Where(...).IsEqualTo(...).ExecuteSingle<...>(); Throws exception on ExecuteSingle() method (configuration section was not found) while using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(ConnectionString)) { Throws exception on new SharedDbConnectionScope() (configuration section was not found) So the question is: Is there any way to pass the settings runtime to bypass the configuration section lookup as I don't want to add any subsonic specific configuration to devenv.configuration Thanks

  • doctrine findby relation

    - by iggnition
    I'm having trouble selecting a subset of data with doctrine. I have 3 tables Location Contact Contact_location The contact and location tables hold a name and an id the other table holds only ID's. For instance: Location loc_id: 1 name: detroit Contact contact_id: 1 name: Mike Contact_location loc_id: 1 contact_id: 1 In doctrine there is a many to many relation between the location and contact tables with contact_location as the ref_class. What i want to do is on my location page i want to find all contacts where for instance the loc_id = 1. I tried: $this->installedbases = Doctrine::getTable('contact')->findByloc_id(1); hoping doctrine would see the relation and get it, but it does not. How can i make doctrine search in relevant related tables? I read it can be done using Findby but i find the documentation unclear.

  • ASP.net 2.0 Gridview with Expanding Panel Rows -- How to build Panel "on the fly"

    - by jlrolin
    I'm currently building a Gridview that has expandable rows. Each row contains a dynamically created Panel of Form elements. Right now, I have a javascript function that expands (or in my case, makes visible) the panel when an Image is clicked on the Gridview row. My question is... is there a more efficient way of doing this. Instead of pulling all my data to begin with and building each new row as I Databind, is there a way to simple create the row with the Panel full of textboxes and dropdownlists on the fly when the user clicks the Expand button?" I'd like to limit the server calls by doing it that way instead of how I'm currently doing it, looping through every row and creating a new panel with form elements and inserting that into a row that is hidden.

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.

  • To store images in SQL or not?

    - by Brett
    Generally, I had thought it was always better to store images in the filesystem and link to it via the database entry. However, I am trying to optimize my db design and am having a few questions. My images are all really small thumbmails in black and white (not greyscale, but true B&W) and are 70x70 in size. If we take the images (which is basically a 2D array of 1 and 0), it can be stored as binary data that would be approximately 600 bytes each. So my question is whether querying the 600 bytes stored in a db would be faster than querying a link followed by accessing the filesystem; assuming there are a lot of "image" queries being made. Does anyone have any experience with this area? If it matters, I am using MySQL, and MonetDB (separately, but have the same question for both). Many thanks, Brett

  • Tutorials for .NET database app using SQLite

    - by ChrisC
    I have some MS Access experience, and had a class on console c++ apps, now I am trying to develop my first program. It's a little C# db app. I have the db tables and columns planned and keyed into VS, but that's where I'm stuck. I'm needing C#/VS tutorials that will guide me on configuring relationships, datatyping, etc, on the db so I can get it ready for testing of the schema. The only tutorials I've been able to find either talk about general db basics (ie, not helping me with VS/C#), or about C# communications with an existing SQL db. Thank you. (In case it matters, I'm using the open source System.Data.SQLite (sqlite.phxsoftware.com) for the db. I chose it over SQL Server CE after seeing a comparison between the two. Also I wanted a server-less version of SQL because this little app will be on other people's computers and I want to to do as little support as possible.)

  • Workflow Foundation: How to create Receive activity with custom message in xaml designer?

    - by Petr Felzmann
    I need to have Receive activity which can receive my custom data. I found examples, but all use coded workflows like such public class ProcessRequest : Activity { public ProcessRequest() { Variable request = new Variable { Name = "request" }; Receive receiveRequest = new Receive { ServiceContractName = "IProcessRequest", OperationName = "Foo", CanCreateInstance = true, Content = ReceiveContent.Create(new OutArgument(request)) }; } } The main point is that Receive.Content property. It is not clear for me how I can do it in XAML designer. What I have to set in the dialog of the Content property - Message or Parameters and what to set inside those options? Thanks for the light!

  • Delayed "rendering" of WPF/Silverlight Dependency Properties?

    - by Aardvark
    Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

  • Run a shell command with arguments from powershell script

    - by Mike Weerasinghe
    Hello, I need to extract and save a some tables from a remote SQL database using bcp. I would like to write a powershell script to invoke bcp for each table and save the data. So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead. This must be something really easy that I am not getting. #commands bcp database.dbo.tablename out c:\temp\users.txt -N -t, -U uname -P pwd -S <servername> $bcp_path = "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\bcp.exe" $serverinfo =@{} $serverinfo.add('table','database.dbo.tablename') $serverinfo.add('uid','uname') $serverinfo.add('pwd','pwd') $serverinfo.add('server','servername') $out_path= "c:\Temp\db\" $args = "$($serverinfo['table']) out $($out_path)test.dat -N -t, -U $($serverinfo['uid']) -P $($serverinfo['pwd']) -S $($serverinfo['server'])" #this is the part I can't figure out & $bcp_path $args

  • llvm's getelementptr instruction with array types

    - by vava
    I'm trying to use array type in llvm and can't get a hold of it yet. As far as I can understand from documentation, array should grow all by itself. But how does it happen, should I just getelementptr with whatever index I have and it'll grow so that index will still be in bounds? That's not what happens, I get all sorts of funny problems which hide away the moment I create array big enough to accommodate all my data. So, should the following code work by itself or I have to call something else for array to increase it's size? %stack = alloca [0 x i32] ; <[0 x i32]*> %"stack[idx]" = getelementptr [0 x i32]* %stack, i32 0, i32 1 ; <i32*>

    Well, it figures that Loadrunner is not easy to install. Apprently, we need: ? .NET Framework 3.5 ? Microsoft Data Access Components (MDAC) 2.8 SP1 (or later) ? Microsoft Windows Installer 3.1 ? Microsoft Core XML Services (MSXML) 6.0 ? Microsoft Visual C++ 2005 Redistributable Package (x86) ? Microsoft Visual C++ 2008 Redistributable Package (x86) ? Web Services Enhancements (WSE) 2.0 SP3 for Microsoft .NET Redistributable Runtime MSI ? Web Services Enhancements (WSE) 3.0 for Microsoft .NET Redistributable Runtime MSI Once done, I'm still trying to figure out how to execute this thing. Has anyone gone through the same experience with it ?

  • How to show validation messages in MVC?

    - by Ian Boyd
    When a user tries to click:        Save and they have entered in some invalid data, i want to notify them. This can be with methods such as: directing their attention to the thing that needs their attention with a balloon hint automatically dropping down a combo-box triggering an animation showing a modal dialog box etc What is the mechanism where a controller tells the view to show a validation message for some controls, given that different views have different notification methods? p.s. the controller doesn't know the order that controls are physically arranged in the view (e.g. LTR locale wants to notify the user in a top-down-left-to-right visual order, while RTL locale wants to notify the user in a bottom-up-right-to-left order)

  • Two Key HashSet?

    - by athena
    I need a HashSet implementation where the elements are a pair of Integers eg. Set s = { {1,2} , {3,4} , {1,4}}. Here the set s has 3 elements. This kind of two key HashSet is needed in many situations like, I have a relation in my database where the candidate key is a combination of two columns. Is there some library which already provides this? If no such implementation is available, then rather then implementing the entire data structure from scratch, will it be easier (and efficient?) to extend the HashSet implementation in Java?

  • Diff between $.ajaxSetup and $.ajax in jquery

    - by Deeptechtons
    title is a bit misleading but i would like to know internally (what happens during ajax request) when i execute Code 1 and Code 2 in turns Code 1 $.ajax({url:"1.aspx/HelloWorld",type:"GET",dataType:"json",contentType:"application/json"}); Code 2 $.ajaxSetup({ contentType: "application/json", dataType: "json" }); $.get("1.aspx/HelloWorld","",$.noop,"json"); i ask this because the method HelloWorld in page 1.aspx is executed correctly when run Code 1. But the seconds one refuses to invoke the pageMethod. I have set the ContentType and data as expected but the second request in Code 2 refuses to invoke the method does anyone have a reason for this ?

  • Is there any killer application for Ontology/semantics/OWL/RDF yet?

    - by narnirajesh
    Hi Guys, I got interested in semantic technologies after reading a lot of books, blogs and articles on the net saying that it would make data machine-understandable, allow intelligent agents make great reasoning, automated & dynamic service composition etc.. I am still reading the same stuff from 2 years. The number of articles/blogs/semantic-conferences have increased considerably. But I am still unable to see any killer-application. Why is it so? Or is there some application/product (commercial/open-source) already existing, which actually is doing all that being boasted of? To put it more precisely, is there any product that leverages semantic technologies (esp RDF/OWL/SPARQL) and is delivering functionality/performance/maintainability, which would not have been possible with the existing (no-semantic) technologies? Some product that is completely dependent on semantic technologies and really adds value to the customers and generating revenues?

  • Problem creating ObjectContext from different project inside solution.

    - by Levelbit
    I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

  • Django - Form validation error

    - by Igor G.
    Hello, I have a model like this: class Entity(models.Model): entity_name = models.CharField(max_length=100) entity_id = models.CharField(max_length=30, primary_key=True) entity_parent = models.CharField(max_length=100, null=True) photo_id = models.CharField(max_length=100, null=True) username = models.CharField(max_length=100, null=True) date_matched_on = models.CharField(max_length=100, null=True) status = models.CharField(max_length=30, default="Checked In") def __unicode__(self): return self.entity_name class Meta: app_label = 'match' ordering = ('entity_name','date_matched_on') verbose_name_plural='Entities' I also have a view like this: def photo_match(request): ''' performs an update in the db when a user chooses a photo ''' form = EntityForm(request.POST) form.save() And my EntityForm looks like this: class EntityForm(ModelForm): class Meta: model = Entity My template's form returns a POST back to the view with the following values: {u'username': [u'admin'], u'entity_parent': [u'PERSON'], u'entity_id': [u'152097'], u'photo_id': [u'2200734'], u'entity_name': [u'A.J. McLean'], u'status': [u'Checked Out'], u'date_matched_on': [u'5/20/2010 10:57 AM']} And form.save() throws this error: Exception in photo_match: The Entity could not be changed because the data didn't validate. I have been trying to figure out why this is happening, but cannot pinpoint the exact problem. I can change my Entities in the admin interface just fine. If anybody has a clue about this I would greatly appreciate it! Thanks, Igor

  • C#, Linq, Dynamic Query: Code to filter a Dynamic query outside of the Repository

    - by Dr. Zim
    If you do something like this in your Repository: IQueryable<CarClass> GetCars(string condition, params object[] values) { return db.Cars.Where(condition, values); } And you set the condition and values outside of the repository: string condition = "CarMake == @Make"; object[] values = new string[] { Make = "Ford" }; var result = myRepo.GetCars( condition, values); How would you be able to sort the result outside of the repository with Dynamic Query? return View( "myView", result.OrderBy("Price")); Somehow I am losing the DynamicQuery nature when the data exits from the repository. And yes, I haven't worked out how to return the CarClass type where you would normally do a Select new Carclass { fieldName = m.fieldName, ... }

  • WPF - Virtualizing an ItemsControl?

    - by Rachel
    I have an ItemsControl containing a list of data that I would like to virtualize, however VirtualizingStackPanel.IsVirtualizing="True" does not seem to work with an ItemsControl. Is this really the case or is there another way of doing this that I am not aware of? To test I have been using the following block of code: <ItemsControl VirtualizingStackPanel.IsVirtualizing="True" ItemsSource="{Binding Path=AccountViews.Tables[0]}"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Initialized="TextBlock_Initialized" Margin="5,50,5,50" Text="{Binding Path=Name}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> If I change the ItemsControl to a ListBox, I can see that the Initialized function only runs a handful of times (the huge margins are just so I only have to go through a few records), however as an ItemsControl every item gets initialized. I have tried setting the ItemsControlPanelTemplate to a VirtualizingStackPanel but that doesn't seem to help.
