I have a custom class library that performs validation. I want to open up this class for use within Javascript. I understand that I can easily achieve this by utilizing WebServices/WCF or by creating a function on my page with the WebMethod attribute, but it'd be nice not to have to set all that up for every project.
Ideally I'd like to just add the WebMethod attribute to my class library methods and then call them using Javascript.
I have two projects in one solution :
Class Library for my BLL and DAL classes Web Application for my PL
Now I just use the keyword "using" in the BLL and DAL classes and get access to their methods easily. but now I try to reference the BLL and DAL in the web application project through the "using" keyword but it won't let me (the name space couldn't be found (are you missing reference ?)) .. then I tried to reference the library's dll (grabbed it from the ClassLibrary/bin/debug) and the same error just popped out again!
Summery:
My solution consists of two projects (ClassLibrary and a WebApplication) and I want to use/reference the classes/dlls of the class library in the web application
I've moved a class in my project into a class Library in the same solution. I've added a reference in the web project to the class library.
How do I access the methods in the class library?
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.
Why is the session turning out to be null?
I created a Class library for WCS service (MyWCFServiceLibrary) to access data form my database. The database connection strings have been defined in Properties->Settings.settings. The endpoints are defined in the app.config. Tracing and logging is set to write to files on local server. This service is hosted by a .net web service. This webservice refrences the WCF service using MyWCFServiceLibrary.dll and MyWCFServiceLibrary.pdb. The web service is hosted in IIS. All this setup is working fine on the development environment.Now I want to deploy this in the QA environment. Since I am a newbie with WCF, I would appreciate some help on what needs to be done for deploying this on the QA server.1. Do I need to recompile the MyWCFServiceLibrary.dll after changing the connectionstring to point to QA database and tracing and loggint paths to the new server?2. Is there anything that needs to be done with end points or anything else?
View 1 RepliesI 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.
View 3 RepliesI 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?
recommend a data access class / helper class for Access databases, similar to the sqlhelper class found in the (Data Access Application Block)?

View 2 RepliesI have a web Application and have created a seperate class library project.I am trying to use the Class Library by referencing it in the Web Application. I am doing this by right clicking the web application and clicking 'Add Reference...'. I then browse to my Class library and click ok. This gets added to a Bin folder in my web application.The problem is I can't actually get any of the objects that are in the Clas Library. I have tried adding a using statement to the top of the page. It tells me that the object could not be found (are you missing a using directive or an assembly reference?)Can anyone tell me what I'm doing wrong?

View 5 RepliesI have a pagemethod defined with the attribute [WebMethod]. The pagemethod accesses the session with no problem (HttpContext.Current.Session).
However I just read somewhere that in order to access the session in a WebMethod, you need to define it like so: [WebMethod(EnableSession=true)]
So my question is, what gives? How come I can access the session even though I dont have that code? Apparently EnableSession defaults to false if its missing, so I should not be able to access the session. The web application uses ASP.NET 3.5 and uses InProc Cookieless sessions.

View 6 RepliesMy team and I have a asp.net web forms application and are using several class libraries. In one of those libraries, we are trying to consume a web service. The web reference was added in the web app project and the appropriate references have been added. The app compiles. When attempting to consume said web service in the class library, the credentials don't seem to work, and the call fails. However, if we take the web service call out of the class library, and consume it within the web app, it works.
View 5 RepliesI 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.

View 5 RepliesMy problem today is that I am having trouble shifting some functionality, that is being used in multiple applications, from the applications themselves to a class library I have started building. The issue comes in the fact the code was written to utilize Response objects as seen below...
[Code]....
This is all currently within a function called "DownloadDocument". I continue to have issues running any of the Response object functionality. I usually get the error saying, "Response is not available in this context", is there anyway to use a Response object in a class library file?
I am trying to implement the TinyMCE Spellcheck plugin that uses GoogleSpell. The thing is I am trying to install it in an MVC environment. I started by referencing the .NET class Library DLL (MoxieCode.TinyMCE) in my project. Then, I added this code to my web.config:
<system.webServer>
<handlers>
<add name="TinyMCE" verb="GET,HEAD,POST" path="TinyMCE.ashx" type="Moxiecode.TinyMCE.Web.HttpHandler,Moxiecode.TinyMCE" />
</handlers>
<!--previously existing rules-->
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
I then added these lines to my tinyMCE.init({}); call:
plugins: "spellchecker",
theme_advanced_buttons3: "spellchecker",
spellchecker_languages : "English=en",
spellchecker_rpc_url : "TinyMCE.ashx?module=SpellChecker",
These steps are outlined in the tutorial here. I then followed instructions from this stack overflow post which recommended the following modification to global.asax to make it mvc friendly:
routes.IgnoreRoute("TinyMCE.ashx");
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
Everything seems fine accept that when I browse to /TinyMCE.ashx i get this error:
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /TinyMCE.ashx
Why can't asp.net mvc process that url?
how to create a class library file and how to implement in web forms?
