Web Forms :: Multiple End Points With Multiple Contract And Class Using WCF?
May 7, 2015
I am developing WCF services with single Contract, but now i need to create multiple Contract & Class with multiple endpoints. My class hierarchy is as follows
Employee :IEmployee
{
}
User : IUser
{
}
I have 2 Interface IEmployee, IUser n 2 Class Employee, User. Creating different endpoints with same binding.
I have an ASP Chart (v4) which displays the data I need perfectly. I want it to show labels at the top of the data points and I am having some difficulty with it.
Here is my code that works for both series but does not display the labels:
I have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.
Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?
Can some explain me the difference between Message Contract and DataContract .i'm new to wcf.. so please give the brief explanation or provide me some code snippets
I am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.
I'm building an application where custom modules may be developed and "dropped in" to the system, where they can be picked up and utilized.
I'm building a forum module and have a user control to create a login/registration region. I plan on using a struct to store the user session data. However, i need this class structure to be shared between the forum module and the login/registration control.
Because the functionality is to be contained in the module's folder, i cant add any assemblies to the app_code folder.
How can i share a class or struct among two user controls?
I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.
I create reports sometimes with a gridview and export the data to excel. Lets say I have like multiple gridviews and I wanted to export each gridview to excel under its own spreadsheet.
So gridview1, gridview2, gridview3 are exported to excel under $heet1, $heet2, $heet3.
I know how to export multiple gridviews to 1 excel sheet but I don't know how to export them separately under their own spreadsheet.
I've been researching online, and i'm continously searching, but does anyone know how to do what i'm trying to do with the gridview and excel or is this not possible?
I've scenerio where i've two dropdownlist box (one dependent on other, displays handset brand name and on selection displays the respective model name), two combolistbox which is bounded to their respective datasource(Displays the fault and accessories).
Now i've to update the three tables booking(Handsetid, Brand,model), accessories(handsetId,AcesoriesID) and fault(handsetID,faultID). Ive to update multiple rows in Accessories and fault.
These controls are present in datagridview EditTemplate
I have a class in my App_Code folder called Order. On one of my pages I am trying to create two different orders using this class.
[Code]....
When I run the page each of the Response.Write statements ouputs a 2. But this is not correct. One should be 3 and the other should be 2. Does anyone know why this is not working?

Private Order1 As Order Private Order2 As Order Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs) Handles Me.Load Dim CartID As String = 4525543 Order1 = GetOrderFromDatabase(CartID) Order2 = Order1 Order2.Shipping = 3 Order1.Shipping = 2 Response.Write(o.Shipping) Response.Write(Order2.Shipping) End Sub

I am used to making separate Business Object and List<> classes for my DB tables. Sometimes I just have a basic task in hand as displaying a list of year for a search box or having some values in a drop down.
Right now I am ending up with a lot of separate classes and List classes<> for these basic operations.
How can I make a single class for some basic tasks as these by using generics? I want to have single class for some methods like get current year, employee names, Department Name/Code, Title etc. I am using .NET 2.0.
Edit After some searching, I found that I can achieve similar tasks by creating a DTO namespace.
What I don't get right now is how to create multiple classes inside my DTO class. Say 1 class for just returning 'year', One for 'Employee Name/Code' and so on inside the single DTO class.
I have a Solution with a web project and some class libraries. The enumerations are in a the enumerations folder within my web project. I would like to make some of the enumerations available to other class libraries within my Solution. Should I just add another class library and call it Enumerations to my Solution so that all class libraries and my web project can access them?
I was just wondering, let's say I created a Method that is in a partial class in App_Code, and this Method would replace the same type of Method that would otherwise be in many files, and so, since it would be called from many files and would probably be called and used very frequently especially because of this. Would this overload this class? I'm not saying what would most likely happen, I'm just asking if it would be even remotely possible?
I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?
