Multithreading - Create Custom Objects/list Of Custom Objects In .NET?

Jan 24, 2010

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String

In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

Updating Webservice With Objects When App Exits?

Jun 13, 2011

Im working on a silverlight application where a user can create, edit, delete objects. The changes they make are placed in a queue which is processed every 4 minutes. When it is processed, the updates are sent over an async web method call to be saved in a sql database, one at a time. When the first update finishes, the next starts.Im having a problem when a user makes a change and then exits the browser app before the 4 minute timer has expired.Currently the changes are getting lost.Ive built on what the guy working on this before me has done, and explored the Dispose and Finalize methods, trying to start the update process when the factory is being shut down, but that isnt working due to the async nature of the web service calls. I get errors saying needed objects have already been disposed of.

VS 2010 Custom Objects And Properties

Nov 13, 2011

I'm working on a project where I need to information on all the monitors connected to a computer and then write a configuration file based on that. I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.

Accessing Objects From Within A Custom Object List

Mar 3, 2009

OK - for starters - I'm not even sure that the title of this thread accurately describes what I want to do - but I had trouble verbalizing it. So I will give this a try: In my application, I have a custom object, call it myObject. In addition, I have another custom object called myObjectList which is basically a List(Of myObject).

Up until this point, all of the functions that I have been working with in my BLL and DAL have been shared - I haven't needed a specific instance of my object thus far. I currently need to write a function that finds a particular myObject within myObjectList and returns to me myObject. I know that the List(Of T) has a find method, but from what I have read so far - I don't think it is what I want (doesn't it return true or false? -and also, do I need an existing object to pass to it to see if it is in the list?)

Bind A List Of Custom Objects To A Listbox Control?

Jun 25, 2010

vs2010 vb.net WPF project

This is an experiment to learn something.

I have a class called logitem

it has a datetime property, and a message as string property

I have declared myLogEntries as List(of logItem)

I have a ListBox.

Ok now what?

I have searched but i am getting lost in all the examples.

I have set the ItemsSource=myLogEntries

I think i need a datatemplate or maybe to specify binding source.

I am doing all this in the wpf form loaded event.

I guess i need a sample code for binding a list of collection to a listbox.

Form Is Not Updating After Custom Class Event Is Fired

Sep 24, 2010

I'm having an issue where my main form isn't updating even though I see the event fire off. Let me explain the situation and share some of my code which I'm sure will be horrible since I'm an amateur. I created a class to take in the settings for running a process in the background. I add some custom events in that class so I could use that in my form instead of a timer.

Implementation - Loop To Update Properties Of Each Object Of A Set Of Custom Objects

Jan 4, 2010

I am using a loop to update properties of each object of a set of custom objects. The routine knows which controls to update because the controls value is not empty, I don't want the routine setting the corresponding properties to nothing when the control is empty. Now I know how to do this perfectly fine with IF statements such as:

CODE:

But this feels really redundant doing that same IF block over and over for each property/control combination, I thought about creating a separate routine that takes the control as an argument and does all the repetitive IF blocks but I don't know how I could also pass an object property to tell the routine to update that particular property.

Implementing IComparer For Custom Objects After Converting A Dictionary To SortedDictionary?

Jun 5, 2012

I'm having trouble implementing an IComparer method. Essentially, I want to compare the properties of two custom objects (the properties are of type integer).dE is a Dictionary(Of String, customObj)prTabIndex is a property of customObj and is of type Integer (these hold true for all examples)After some more searching I found this thread which suggested 3 things: a List approach, utilizing LINQ, and using some C# 3.0 features. I've tried three different ways:...rolling my own IComparer implementation:

Public m As Sub(ByRef d As Dictionary(of String, customObj))
Dim sortedD As New SortedDictionary(Of String, customObj)(d, myCompare)
End Sub

[code]....

Note that VS2008 has underlined 'dE.ToDictionary...' (to the end of the line) and giving me two messages depending on where I hover my mouse:

1) "Data type(s) of the type parameter(s) in extension method 'signature' As 'signature defined in 'System.Linq.Enumerable cannot be inferred from these arguments. Specifying the data types explicitly might correct this error. Seen while hovering over "ToDictionary".

2) Nested function does not have the same signature as delegate 'signature'. Seen while hovering over anything after "ToDictionary".

Q1) How far off am I in each of the implementations?

Q2) Which one is the computationally least expensive? Why?

Q3) Which one is the computationally most expensive? Why?

.net - Handle Null Nested Objects In RDLC Report That Is Bound To Custom Assembly Object Datasource?

Aug 27, 2009

I have an RDLC report that I am rendering directly to the Response Stream as PDF (rather than using the ReportViewer). In the code that renders the report, it's DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can't seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:

Public Class ClassA
Public Id As Integer
Public Name As String

[Code]....

the report displays "#Error" if TheNestedObject is null. If TheNestedObject is not null, it correctly displays the Name.

Two Objects That Are Raising Some Events - Pressing A Button - Raise A Custom Event, Then Execute A Method And Then Close The Form

Mar 30, 2011

Problem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !

Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form

In that case, you may use a code similar to this

Event BeepIt()

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent BeepIt()

Asp.net - ObjectDataSource.Select() Not Always Firing On Page Postback

May 15, 2012

I have a form with:

[Code]...

Whenever I change the value of MyTextBox and press MySubmitButton, the select method of MyObjectDataSource is invoked and everything works OK. But if I change the value of any of my check boxes (without changing the value of MyTextBox) and press MySubmitButton, the select method is not invoked, thus the "MyObjectDataSource_Selecting" event doesn't take place and I get the same results as before.

One way I found to work around this was to explicitly invoke MyGridView.DataBind method whenever MySubmitButton was clicked. Is this the best way to handle these type of parameters? What I am afraid is that this may cause the select method to be called twice making the page slower.

Building A ASP.NET Profile Wrapper To Use With An ObjectDataSource Control?

Dec 26, 2011

building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.

Namespace SiteMemberShip
Public Class ProfileWrapper
Private FirstName As String
Private MiddleName As String

IDE :: Pass Parameters To Stored Procedure Through ObjectDataSource?

Jun 7, 2007

I am building a three tierd app, and therefore have all my data access methods in a class by itself.This class only calls stored procedures, basically, I need to pass in the following:

1) stored procedure name as string

2) parameters as IDataParameter() -- an array of parameters

3) other fields ( not important to this discussion)

If I use a GridView on my web form and choose an ObjectDataSourceObjectDataSource, and then choose my business object and method, since the method is a call to a stored procedure with a parameter array, I don't know how to pass it values in the IDataParameter format.The Method Signature listed on the wizard is "RunSP(String spname, IDataParameter[] params), returns SqlDataReader" which basically is calling a method called RunSP with two parameters, of which the second parameter is a parameter array for a stored proc.

C# - Using ObjectDataSource And DataObjectTypeName - Handle Delete Methods With Just An Id Parameter?

May 27, 2009

If I have an ObjectDataSource setup like:

<asp:ObjectDataSource
ID="ObjectDataSource1"
runat="server" [code].....

How do I get the objectdatasource to use the Delete method with the parameter that is not an Employee object? what is the recommended alternative architecture?

Edit:

To clarify, I want to use the method signature on my data/business object as shown above, however if I try to allow an Employee object to be passed into some of the methods using DataObjectTypeName, then I seemingly lose the ability to have some methods take just an integer id for instance.If I do not use the DataObjectTypeName, then I have to place all the method parameters in the ObjectDataSource and change the methods on the data/business object to match, this seems like a bad design choice because as the Employee object changes I will have to update each of these methods.

Getting The Selected Row From A FormView Bound To ObjectDataSource In The ItemUpdating Event?

Oct 16, 2010

I have to maintain an ASP.net application in VB.Net.There is a page with a FormView bound to a ObjectDataSource.I have to add some business logic on the ItemUpdating event of this FormView.Unfortunately, some the data that I need to add this business logic is not exposed on the FormView user-interface itself, so I can not use FindControl to get the values (I could add the controls, bind them to the fields I need and set their visible property to true, but that's ugly).
