I'm trying to study mvc and I have found my self dealing with this problem/ questionI have a DB with the table Customer and I have create a Entity data model (with the table customer).Now I have also made a class name customer and I'm getting an error saying " Missing partial modifier on declaration of type 'MvcSite.Models.Customer'; another partial declaration of this type exists
"
[Code]....
What I'm trying to do is using this class to write new costumers to the DB , ( I do know how to do so directly , but if I'm not Mistaking using the class is the Correct way to do so (?)If I'm changing the class name to customers , how is it suppose to write back to the DB?
I saw in Internet that I can use the methode InsertOnSubmit but when I do db.Customer.InsertOnSubmit in order to inset the data in the Customers table, the method isn't recognized by the intellisens.
Since we can access the private data member of base class in the derived class with the help of friend function. How can we do the same in C# asp.net? I mean whats the alternative of friend function in C# asp.net
Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
I first need to apologize in case this has been answered before but I'm a newbie (green as they come) and this error keeps popping up even before I start debugging! There are two errors and the second one is:" Error 2
Missing partial modifier on declaration of type 'WFPKenya2.WFPKenya2'; another partial declaration of this type exists"
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(); }
I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.
am using class diagram of visual studio 2008as you can see the image i need show to user that the period and calendar classes have the idMarket property that refers to market classhow can i do this?
I have build a UserControl with separate code behind file.In that code behind file i have defined some public properties in the Partial class of user control that was automatically generated.Those properties will initialize some properties of controls that are used in the control.Now, in .aspx page i used this User Control and initialized the public properties through code behind of aspx page for dynamic contents.
In my MVC project, I am trying to setup a base product class that will be inherited by a more specific class later. Here is my scenario. I have a table called ProductBase, it contains three fields, BaseProductId(PK), CatalogNum, and ListPrice. Every product in the system will share these attributes. Next, I have a table called Shirt, with three fields BaseProductId(PK, FK), Color, and Size.
I then setup an Entity Data Model that pulled in both of these tables and created classes BaseProduct and Shirt. So, in my model, I want to do something like this:
[Code]....
The main problem I have with this, is that if I do any kind of condition on CatalogNum or ListPrice, then my performance goes to crap. One of the main things we will want to do is something like this:
[Code]....
This takes an enormous performance hit, and I suspect it is because the partial class above returns to the database for each shirt.
The other problem I have with this approach, is that I cannot force the properties for the Shirt. What if I make a change to the BaseProduct? What happens when I have multiple product types, will I have to repeat this code? I assume I will need to make a change with the entity data model, but I am unsure where to begin.
I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?
I am going to have multiple "types" of an object and I am really not sure how best to retrieve/save those multiple types without having a separate save/retrieve for each type.
My classes:
[Code]....
I hope this makes sense. I'd rather not add a "type" column as I have this in another part of my database and I am not really liking it too much
UPDATE
Here's more info/questions for clarification, if necessary.
I'm really at a loss for how to incorporate them into my repository pattern.
When I call getEvaluation, I want it to return an abstract Evaluation, but I'm struggling with this code. Same with Saving - any insight on this would be excellent
UPDATE 2
Database: Evaluations Id (PK) Comment EvaluationType1 Id (FK to Evaluations.Id) Field EvaluationType1 Id (FK to Evaluations.Id) Field
So, in getEvaluation(int id), I need to figure out what type of Evaluation they want. Does this mean I should pass in a type? Same is true in saveEvaluation, But I can do a switch/function map to see what Type it is.
i have an application consisting of two asp.net projects. And i have have a BasePage which inherits System.Web.UI.Page and have the class some core logic which i require in all of my pages(Implemented in BasePage.cs). So all my pages inherit this BasePage.cs . Now can an Webservice inherit the same class apart from the normal webservice class System.Web.Services.WebService
I have a class instance which is created by using Activator.CreateInstance() method. That class instance contains helper methods which are frequently used throughout the application. In order to avoid creating the instance multiple times, I'm just thinking about implementing an appropriate caching mechanism. The following consideration should be taken into account:
1) I can't use static class and methods. 2) There are around 6 instances (1 instance per class) per App Domain.
How can I to use System.Drawing.Bitmap class into athoer class?
using System.Data; using System.Collections; using System.Globalization; using System.Data.SqlClient; using System.Collections.Generic; using System.Globalization; using System.Text; namespace University { public class Class1 { System.Drawing.Bitmap BMP=new System.Drawing .Bitmap(); } }
when I use System.Drawing.Bitmap gives error this class does not exists
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.
Here When i create object of Class InheritingOneConstruntor value of public field var1 is zero at last. But when i checked step by step through debugging i found that when base class's New() constructor is called, for a moment all var1's value becomes 89. All var1 means at all locations where var1 is used i.e., in base class and in child class.But the moment control exits New() constructor of base class, var1's value again becomes zero. Why it happend ?
Suppose we declare and define the variable in one class let say FirstClass and we want to use that variable in another class let say SecondClass which is outside of FirstClass .how to do this?
I have an existing class for an input, is it possible to add an additional class for the object in C#.net, instead of doing a if/else and not having a preset class on the object in the first place?
I have a WindowsForm that has a DataGridView that shows output of my app. The class with the button is DriveRecursion_Results.cs. I want it so that once the button is pushed by the user, my method FileCleanUp() in my SanitizeFileNames class is called. I'm not quite sure how to do this though.Here is the code for both classes:
public partial class DriveRecursion_Results : Form public DriveRecursion_Results() InitializeComponent(); private void listView1_SelectedIndexChanged(object sender, EventArgs e) [code]...
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?
