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?)

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?

Display A List (Of Object) Which Has Single Objects And Child List (Of Object)?

Sep 6, 2011

Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.

I have created a list of another class and loaded the list with data. using breakpoints I can see that the data is loading and visible in my form page. However, when I attempt to access the list using a For Each loop, I get an error saying that "Value of type Customer can not be converted to Integer"I am trying to follow examples from tutorials on accessing list elements, but they are never lists of objects, so I am not sure what I am doing wrong.

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.

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.

.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.

Select Object Member From Combobox List Of Objects

Nov 16, 2011

I have a combo box that is populated with a list of objects (corresponding to all employee rows from a database that meet the criteria IsTech). These are not entity objects though, I have created my own class that stores the member values of each row from the DB. I have set the DisplayMemberPath to EmployeeId so the Combo box display the EmployeeId ( an integer ) member of my object. Ie. right now there are only 2 IsTech employees in my DB so the combobox displays the numbers 3 and 8 ( their EmployeeIDs).

VS 2010 : Find An Object With Certain Attribute Value In A List Of Objects?

Oct 13, 2011

I have a list of objects, each object has a score attribute,The list of scores needs to be combined on the player ID to become a totaled score or series. My current thought process is to For Each through the list of individual games, and add the score attribute to a new list of scores with the same objects. So one list would be like:

clsGame(ID Number, Sore)
dim ScoreList as list(of clsGames)
ScoreList.Add(New clsGame(11, 244)
ScoreList.Add(New clsGame(11, 333)
ScoreList.Add(New clsGame(11, 444)

Then go through combining on like ID's to make a new list of games, that would actually be the series.

Dim SeriesList as new list(of clsClasses)
For each game as clsGame in ScoreList
'cycle through the list of series seeing if an ID matches, if so add the score onto that ID
Else

[code]....

Now I don't know how to add the player if its not in the seiries list without doing a heck of a lot more for each statements. If I add it after the end if then it will be added even if it is in the list..I tried playing around with List.Contains method, but I could only see if it contaned the exact same values i.e

SeiresList.Contains(game)

and because the scores are different (series vs single game) it wouldn't match, and I don't know how to see if it contains an object with just one of the attributes the same...

VS 2010 Sort List Of Objects, Based On Object Parameter

Oct 10, 2011

I made an object that has several properties one of which is an integer.

I put all the objects into a list, and I wish to sort that list by the integer property, with the object with the highest property at item 0, with the object with the lowest property at the highest item # ( count -1).

I made the list of that item, as in

Dim GameList as new list(of clsGame)

And I wish to do something like the following

GameList.Score.Sort()

What is the syntax to do that? I looked up the MSDN and didn't really understand what it was trying to say

List Of New Custom Object?

Sep 2, 2010

I created a simple (for now) custom object:

VB
Public Class Form1
Dim AllPartFiles As List(Of Part)

[code]....

As I search a folder for files, it returns FilePath as a string for each file in the folder, then assigns a new Part.FullFilePath to the current returned FilePath, then add the Part to AllPartFiles list. So I can retrieve each Part from AllPartFiles later. But everything I try doesnt work.I know below is wrong, but might show what Im trying to do:

VB
Dim Files() As String
Files = System.IO.Directory.GetFiles(RootFolder, "*.ipt")
Dim k As String

[code]....

Create a New Part, change its values, and then add it to AllPartFiles list for later, then repeat?

Bound To A List Object Of A Custom Type Via A BindingSource?

Nov 11, 2010

I have a datagridview that is bound to a list object of a custom type via a BindingSource. From everything I've read, I should be able to click the column headers and the rows sort, This doesn't happen for me. Sortmode is set to automatic and the column headers aren't set to be used for selection so it should work.

I know that I could sort progamatticly but that seems a little bit of a waste given that I should just be able to do it by default.

Sorting A List Based On An ArrayList Within A Custom Object

May 24, 2010

I am using a list to keep track of a number of custom Row objects as follows:

Public Rows As List(Of Row)()
Row has 2 properties, Key (a String) and Cells (an ArrayList).

I need to be able to sort each Row within Rows based on a developer defined index of the Cells ArrayList.

So for example based on the following Rows

Row1.Cells = ("b", "12")
Row2.Cells = ("a", "23")

Rows.Sort(0) would result in Row2 being first in the Rows list. What would be the best way of going about implementing this?

Using List Of Custom Class Object As Data Source For Crystal Report

May 24, 2011

I am trying to find way to design a report using my own custom class. I found links:

1.) How to work in Crystal Report with Object Data Source?

2.) Use .net object as data source in Crystal Report 2008

3.) Binding object with List<> to Crystal Report

4.) How to assign Custom class as datasource in crystal report

They were quite helpful, but I have been stuck in the first step while designing report as my custom class's property is not listed in field list of crystal report design view.[code]When I add my class objects to crystal report I do not get the usertype field from users class in field list.So how can I add usertype field to my field list? Or do I have to take another approach?The reason i wanted to use it as i am:

1.) Showing a form where user can type keyword
2.) program filters the records as per keyword using LINQ
3.) when user clicks the print button, I want to set the filtered records as datasource of my report

Accessing DNS And MWA Objects Programmatically On A Child Domain

Feb 8, 2010

I've created managed code to programmatically provision websites on Windows 2008 servers from a Vista 64-bit workstation.The provisioning covers creating DNS entries, creating a file structure and a the IIS7 site (using Microsoft.Web.Administration aka MWA).I've had to do some DCOM configuration to get it to work through a firewall and it all works on the test server provided I'm in the same domain.I then cloned the Windows Server 2008 Virtual Machine (VM) that the provisioning does work on and then changed the clone's domain to the child domain in the forest where the production servers are sitting.The provisioning user credentials are synchronised on the parent and child domains.So the only change is moving domains and there is an automatically configured trust relationship between the domains.

Provisioning the file system still works on the server on the child domain, but managing DNS and IIS7 now have access issues.I've tried impersonating the Administrator on the child domain (and the thread identity is showing that works) and also had a go with CoInitializeSecurity (though I'm not sure that is appropriate for Win2008 and Vista)to no avail.What I really want to avoid is the need to have to store credentials separately on the workstation - it brings an unwelcome maintenance overhead and the possibility that if the provisioning user's password is changed, then the provisioning will unexpectedly fail on the production servers.Ideally once the provisioning user has logged onto the Vista Workstation, I'd like their credentials to pass through to the servers on the child domains (there are separate DNS and web servers) allowing them to manipulate whatever services (DNS, IIS7, file system) that are necessary.The solutions would seem to be something programmatic (whatever replaced CoInitializeSecurity?) or a Group Policy setting on the child domain may need altering to allow access.However being a humble software developer working out which of the myriad settings (one of the User Rights Assignments perhaps?) is outside my sphere of knowledge.The third alternative is to use Windows Communication Foundation (WCF) but I haven't done much with this yet and what I have indicates that this technology has its own security issues to accommodate.

Accessing Hidden Properties Of Excel 2007 VBa Objects

I need to migrate from Excel 2003 VBA to Excel 2007 VBA. When Microsoft introduced Excel 2007 it removed many objects from the previous versions and added some new objects. Also it hid some properties of particular objects. These hidden properties can be viewed by going to the object browser, right clicking any object and selecting "Show Hidden Members". My problem is I need to access these hidden properties. Is there any way I can access these properties. I can successfully migrate from Excel 2003 VBa to Excel 2007 VBA with the same functionality?

ASP.net User Data Getting Crosses Between Users Accessing Objects?

Jan 4, 2010

I've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.

What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz).Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.

I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue
