Say I have a List(Of Tag) with Tag being an object.

.net - Adding New Object To Generit List Overwrites Previous Values?

Jul 15, 2010

I have a problem with a generic list, which consists of intances of a class i created. I am just amazed, each time I add a new object to the list, it overwrites the previous entries. Here is a code sample, i just can't beleive it. I am using visual studio 2010:

Dim translations As List(Of TranslatedValue) = New List(Of TranslatedValue)
If Session("ctlTexts") Is Nothing Then
Dim reader As IDataReader = DataAccessFunctions.db.GetDataReader("SELECT [ControlID], [ControlTextEN], [ControlTextDE], [ControlTextBG] FROM [dbo].[tbLanguage]", GetConnectionString)

Make Some Members Available To Only One Object?

Jun 4, 2011

I have an EggSac object which contains references to >100 000 Egg objects. Some variables in the Eggs have to be maintained to be consistent with EggSac, so I want to make these only changeable by EggSac. However EggSac passes references to its Eggs all over the application, so if I use public methods then any other code could modify the secure parts of the Eggs by accident.

What's a proper OO way to make sure only the EggSac object can call the "secure" methods of the Eggs, but still make the "safe" methods available to everyone?

My idea is to split Egg's class into a base class containing only safe methods and a derived class containing the secure methods that only EggSac should have access to. Then EggSac has members of the type of the derived class, but it casts them to their base class whenever something else wants one.

VS 2010 - Permutations Of Array Values With Variable Number Of Members

May 5, 2011

I have a number of arrays (lets say two for the time being, but this needs to be scalable from 1-n). Each array represents a different "parameter" for the application I'm working on. I need to create a multidimensional array containing a set which represents each of the permutations of each of the "parameters". Effectively each row represents each permutation of the selected options for each "parameter" array.

For instance, say the first array of inputs is:
"Blue"
"White"
"Yellow"

And the second:
1
66
95

I need to create an array:
"Blue", 1
"Blue", 66
"Blue", 95
"White", 1
"White", 66
"White", 95
"Yellow", 1
"Yellow", 66
"Yellow", 95

The main work is in the "If Not (OutputTemp Is Nothing)" loop. Effectively I need to access the content in the first array with a "modulus" so that: (using the example above). I'm accessing the rows in the following method
OldArr,NewArr
11
12
13
21
22
23
31
32
33
worked it out.

Here is the code.
Public Class Permutation
Public TitlePrimary As String
Public TitleSecondary As String
Public Order As Integer = 0
Public Values() As Object

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.

Create An "inline" Object To Contain Members For A ComboBox?

Oct 4, 2011

I have an enumeration in the form[code]...

I would like to use these as values in a ComboBox, but I would like to display the strings "My Stuff" and "My Things" respectively.

I'm sure I've seen a method for quickly creating some kind of local object definition where I can assign a string property to be displayed, and a "MyCollections" type property to store the value of the enum element, but I can't for the life of me think of how to explain that to a search engine.

How To Quickly Transform A List(Of Object) Into A List(Of "Object.field")

May 29, 2012

Suppose I have a list of Cat.

Public Class Cat
Public Property id As Guid
Public Property name As String
Public Property race As catRace
End Class

How can I quickly transform this List(Of Cat) into a List(Of Guid) using the id property?

I could do :

Dim newList As List(Of Guid)
For each item in catList
newList.Add(item.id)
Next

But I think there must be a way to do this faster (1 LOC). I just can't find how.

I need to be able to add elements to a copy of mylist.testlist without modifying the global mylist object.

Copy List Object To Another List Object

Jun 15, 2012

I am having a problem when setting VB.NET list object to another.I create an instance on ReadLocations and than create an object of ReadLocation where then I loop through ReadLocations and set ReadLocation1 equal to rl. What happens is that if I then go and change ReadLocation1 to something else (assdfhsd) it will also change the ReadLocations index. I am really confused why it would be doing that unless it is "=" sign means referencing instead of actually setting the value. Please help as I am a C# developer but the program I am modifying is in VB.NET.[code]
