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 have a web service called service1. Is it possible to pass the parameter related to the service to a class library so for e.g.
Service1.service ws = new Service1.service();
Service1.UserDetails ud = null;
now if I call a method that exists in a class and pass ud. Cam i do that because I am trying to do this and I am getting an error. Do i need to add a web
reference to this service in the class library My method call is like this
authenticateUser.Authenticate(ud, UserName);
and in the class libary I have
public void Authenticate( Service1.UserDetails ud , string UserName)
{
}
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!

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 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 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?

How can I use static method of singleton class?
I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?
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.
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 6 RepliesI am to access a method on my master page. I have an error label which I want to update based on error messages I get from my site.
public string ErrorText
{
get { return this.infoLabel.Text; }
set { this.infoLabel.Text = value; }
}
How can I access this from my user control or classes that I set up?
I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?
I 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 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.
