Asp.net - Moving Functionality To A Class Library Project ?
Mar 30, 2011
I have a .net project whose part of the functionality is xls transformation. I now want to move that functionality away from the main project to a separate class library project.
I have no problems moving classes and accessing them, but part of the resources that I wanted to move were xslt files that define the transformations. Those files were originally located in the special asp.net folder: App_Data and then accessed using Server.MapPath(~/App_Data/XSLT/anXsltFile.xslt)
I wanted to move those files to that separate library as well, but not sure how to approach it, and how to access those files within the class library.
I have a Web project in which I defined some methods to parse some webpages. I then save the retrieved data in a DB. Now I have run a lengthy operation(it may take 2 days) in which I continously parse webpage this way.
Can I use the webproject from a Windows project. If I try to add a refference to it it doesn't work. How should I do it? I have used until now an asp.net application, and done the calls to the parsing methods in the pageLoad event but after an hour or so the process stops.
I am developing a project using Visual Studio 2008 in C#, I have added the class library within the project and set up the relevant references and used the relevant using statements.
this is the error message:
Error 28 The type or namespace name 'Domain' does not exist in the namespace 'Forestry.SchoolLibrary' (are you missing an assembly reference?) C:ProjectsSchoolofForestry runkSourceSchoolAccountPresenterEditAccountPresenter.cs 26 40 School
these are my using statements:
using System; using System.Collections.Generic; using System.Configuration; using System.Linq; using System.Data.Linq; using System.Text; using System.Xml; using Forestry.SchoolLibrary.Core.Domain; using Forestry.SchoolLibrary.Properties;
I'm working on an internet application that has been set up as a web SITE project (I know...) in Visual Studio. I need to add additional features/functionality so have added a class library to the project and referred to it in the main web site project.
The issue now arises because I need to make use of core objects which live inside the App_Code directory in the web site project but this project doesn't appear to expose its DLL like web app/ code library projects do. Because of this I can't add a reference to the web site project in the class library to leverage the common site-wide code/objects.
I can't move the stuff out of App_Code so I'm looking for a way to refer to the website project dll from the new class library.
I've created class library project and added service reference to webservice. When i try to use webservice object am not able to access webservice methods.
myservice proxy=new myservice(); proxy.( no methods are coming)?
I have a custom gridview control which is a class library project.I want to be able to specify the css class for the gridview which I can do.But I also want to set a default css stylesheet to the gridview. So if I don't override it using the cssclass property it must get it's cssclass from the default stylesheet I have in my project.
How can I specify the default stylesheet. I have a stylesheet in a folder called "Styles" in my project.
I have one C# windows class library type project which has a web reference whose settings are automatically added in to settings.settings file( Webservice name, type, scope, value).
I also have one separate ASP.net project which has let us as suppose, one page with a button. When I click this button, it calls a method of referred DLL of previous project and control goes there.
When in that project, when control goes in to location where I use this web reference, it tries to get the URL of web reference from settings file and raises an exception - 'The current configuration system does not support user-scoped settings'.
So, What is the way for me to call a c# project having web service in a asp.net project ? This is really a source stopper for our development.
In the development, it works nicely. Until I deported to production, I realise that the component that use those thing .. it just hang. I found that under BIN when it compiled dewaCorp.EUC.TelcoDB.Data.dll.config and open up that file and turn out nothing.
I am implementing a custom membership and role providers where I need to store all the role/membership information in the user's session.
I am implementing these custom providers inside a class library project (different from the website project) and need to access the session in them. The idea is to store the role/membership related information in the session after retrieving them for the first time from the database.
When I try to access the Session using System.Web.HttpContext.Current.Session
I get this as a null object (Object reference not set to an instance of an object.
Does anyone know what could be the reason I am not able to add reference to System.Web. It gives an exclamation(!) symbol in front of the dll under reference folder in VS 1020. I wand to refer to System.Web.Security.MembershipProvider class.
How to access proxy class of a web service which has been referenced in the website project of a solution within a class library project in the same solution?
I mean no web-service reference/setting is added to the class library and instead it needs to be picked from the web project.
I've got an ASP.NET 4 web forms application I'm building in Studio 2010. The solution has two projects. A web forms application and a class library. I have added a reference to the class libraryr project in the web forms project, but when I go a code behind page in the web forms project, it does not recognize the class from the class library and throws the "type or namespace <class> could not be found ...." error. Adding a using <class library projec> does not work either as it does not recognize that.
When I make an asp.net web application and add class libraries to the solution, the website project itself has a folder with the same name/contents as the class library.
Eg I make a web application called Test, add a project which is a class library, to the solution, called testAbc, and then there is a folder at the root of the website project called testAbc with the contents of the class lib.

I read why this happens in a book a while ago but can't quite remember now.
I have list of class files, when i try to run the class files, it showing error as "a project with output type of class library cannot be started directly"
How to run the class file? How to create a dll file.
I have this Control directive in a usercontrol (i've changed the namespace and class name):
<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %> <asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" /> ClassName is a class that lives in a class library and this is the class: namespace Namespace.Path.To { public class ClassName : System.Web.UI.UserControl { protected System.Web.UI.WebControls.TextBox txtComment; protected void Page_Load(object sender, EventArgs e) { HttpContext.Current.Response.Write(txtComment == null); HttpContext.Current.Response.End(); }
Can anyone tell me how to show alert message inside the .cs file of class library project in c#? I am calling a method of cs file in classlibrary project. Whenever the control comes to the alert message statement inside the method, alert message should be shown on the web page(aspx) and the next statement to the alert message statement should not be executed.
I might be asking a dumb question, but I have a client for whom I need to build many websites (10+) (asp.net 3.5) which will all the pages on each site will have the same codebehind, but the sites will launching in different regions and whilst following the same template, will have different content.I have built and launched site 1, and sites 2, 3 & 4 is nearly live, but it occurs to me that as all the sites are basically the same, the code is going to get more complicated to update as it will be duplicated, so if I need to do a bug fix on one site, I'll need to do the fix on all websites (and this is going to get complicated.)
I was wondering if it possible to somehow create a class library of all the current aspx.cs files, reference this dll in each website and then inherit these classes into the .aspx.cs files. So default.aspx in each site would still have a CodeFile of "Default.aspx.cs", but Default.aspx.cs would inherit the corresponing class from the dll:
using WebPagesClass; public partial class _Default : WebPagesClass._Default { }
The reason for doing it like this is that if I need to change any code on a specific website (for minor changes in languages for instance), I can override the page functions and change the parts required. For all other pages which have not cha, I can just copy from a single website.Is this vaguely possible? If not anyone one got any killer suggestions of how to manage so many websites from a single codebase?
I have a VS2010 ASP.NET project saved on my computer that works fine. However, when I move in to my usb and attempt to check if it still works I receive this error:
One or more projects in the solution were not loaded correctly.Please see Output Window for details. The message in the output widow tells me the the file at the location does not exist which, I know because I just moved it. Also, I notices when I checked the suo file via Notepad++ that the file path was hard coded. Is there anyway, to change it so the project will open no matter where it is located.
I am developing asp.net web application on visual studio 10. I want to move this project to another machine running visual studio 10. I have databases and style sheets with my project. Whats the best way to copy this project to another machine preserving all dependencies.
I had to move an asp.net website from Windows 2003 to another server with Windows 2008. Now when I run the website after setting everything up the images will not load. It is a logo that is in a folder named Images. The file is there along with the folder just like on the other site. Any reason this would not work now? Everything else is working except images. Is there something else I missed in the setup?
I created a ASP.NET project under Visual Web Developer 2008. Under that project I had a Database (along with ASPNETDB.MDF) which has about 3/4 tables (I had SQL server 2008). Everything was working fine (like insert, delete, etc.). And I was able to view the tables in database explorer view.
Then I had to format my computer for some reason and I copied the whole project in a USB drive and then after formatting the computer I copied the folder and tried to open it in Visual Web Developer (now I have VWD 2010). I can see the both Database under App_Data folder (ASPNETDB.mdf and the DB I created). ASPNETDB has all the tables and data as expected. But I do not see the tables under the DB I created.
For some time now I am trying to figure out how I can refactor some of my code to reduce redundancy throughout my application. I am just learning the basics of OOP and can create simple classes and methods but my knowledge is limited in terms of practical applicability. The following bit of code illustrates my frustration:
[Code]....
This bit of code is used on several pages of my project in the pages codebehind file. How can I move this to a class file. I don't know how to reference an object like a gridview in a class because it does not exist like it does on the actual page.
I have a project that uses the asp chart control. The project was developed to use .net 4.0 but the server uses version 3.5. I changed the project to 3.5 but now my charts don't work. When I change it it tells me that system.web.DataVisualisation.dll will be removed.
