C# - Order List By Arbitrary Sort Expression?
Mar 2, 2011I have a generic list, like this:
System.Collections.Generic.List<Question> myquestions = new System.Collections.Generic.List<Question>();
And I have a paging example, using a LINQ table acquried from database, doing this for paging:
var questions = context.Questions
.OrderBy(sidx + " " + sord)
.Skip(pageIndex * pageSize)
.Take(pageSize);
Right now, for paging my populated from code list, I have:
var questionss = myquestions
.OrderBy(x => x.Id)
.Skip(pageIndex * pageSize)
.Take(pageSize);
And what I want is being able to order "myquestions" by a string as in the above example. Is that possible?
Add Items To A Listview In A Specific Order?

I have this list view (which is working fine) and i want to find an efficient way of populating it in a specific order, ie by date, by identity etc.
I know i can use linq but as i understand this is inefficient. If m_batchs is a large list of objects then i will looping through this list many, many time (as linq behind the scenes loops through the object collection).

ListView Cells Populating Out Of Order
Aug 5, 2011I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade. When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows
Dim lvi As New ListViewItem(dr("StudentKey").ToString)
For i As Integer = 1 To 4
lvi.SubItems.Add("")
[Code] .....
But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.

Change Order Of Items In A List Sequentially?
Jul 26, 2010I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:
(1) Alpha, (2) Beta, (3) Gamma, (4) Delta, (5) Epsilon, (6) Zeta
2nd List:
(1) Beta, (2) Gamma, (3) Delta, (4) Epsilon, (5) Zeta, (6) Alpha

View 1 RepliesCollection Of Arbitrary Types
Oct 21, 2010I know there's the old, late-bound, VB6 Collections, but I was looking for something like Generics, but either without having to specify the type at compile time, OR finding a clever way to allow the code to determine the type on its own and then call some generic class.Why? I'm bored, and I thought it'd be fun to try and implement my own library for NBT, or NamedBinaryTag.It's the storage format used in the popular Minecraft game.url...I know there are existing implementations out there, but there's no point in copying those if I'm doing this solely as a learning experience to get a better grasp on file streams, byte arrays, endian conversion, and general .NET stuff (I used to fiddle with VB6/VBA a lot, so .NET is a huge change).
What's hanging me up is TAG_Compound. Per that specification, it's essentially a collection of objects of any other Tag type, including additional, nested TAG_Compounds. You can do some freaky nesting/recursion with this kind of a format.I've got a rough outline in my head of how to do the other classes, but the storage of arbitrary types is just making me draw a blank on how to store that in a stub class (clsTagCompound) So that a generic class (clsNBT(Of T)) can use generic functions to access the payload.List(Of T) looks like it could work if I could feed it a common interface. But since a Generic class will be the main component used, its interface is also generic, and that just leads to nasty generics chain (List(Of (clsNBT(Of XXX))).[code]What I'm thinking of doing, is making all derived classes implement INbt(Of T).For clsTagCompound, its SetPayload method will start walking a bytestream after the compound's name field is parsed. For each new TagType that it encounters, it would theoretically call DirectCast on a temp variable Dim'ed to INbt(Of T) to convert it to the class defining that particular TagType.But this doesn't seem to work as planned. I believe my Catch 22 is that to even use clsTagCompound, I still have to define T, and that's where I get stuck again. I somehow need to create an interface that is NOT generic, yet can be applied to all the classes for the various Tag types and still call their GetPayload function to return the payload specific to a particular tag.

Asp.net - Select A Variable TimeSpan With An Arbitrary End Point
Apr 29, 2009I've been working on a Stored Procedure that checks the time, then retrieves records going back over the last full 24 hour period between 8am and the previous 8am. So, for instance, assume that it's currently 10am. The stored procedure looks at the current time, notes that it is past 8am, and sets the query to run backwards 24 hours, from 8am today to 8a yesterday. If it were, say, 7am, the query would be set to check from 8am yesterday to 8am the day before. This was actually relatively simple to do. The SP is meant to be used to retrieve records for a report tracking jobs completed in the given time span.
However, they've come back at me and asked me to change the stored procedure such that the hour the report ends at, and the span of time checked, is configurable from the front-end of the site. I have this working for TimeSpans greater or equal to 24 hours, but am having trouble with spans under that. Here's what I have so far for my logic in the Stored Procedure -
-- Retrieves data on jobs that completed/completed with errors during a given time span.
DECLARE @Hour NVARCHAR(2)
DECLARE @TimeFrame NVARCHAR(2)

Accessing Elements In A Multidimensional Array Of Arbitrary Dimensions?
Jul 3, 2010I'm trying to write some of my own linear algebra methods, and I'd like them to work independent of the number of dimensions of the array. However, there doesn't seem to be any generic method, that I can see, for looking up a particular element in an array of arbitrary size. I mean I could write code to find the rank and then use (), (,), (,,), (,,,), etc, but that seems rather cumbersome.
View 4 RepliesAdding Arbitrary Number Of Controls In Loop At Runtime
Jul 12, 2009How do you add an arbitrary number of controls to a form at run time? With indexed controls I could define the 'seed' control at design time and reference 'clones' of the 'seed' control at run time via the index. Now I must declare each additional instance of the control at run time then set each individual property that differs from the default for that control for each instance. Then I must add the newly declared control to the appropriate container controls collection. I'd like to do this in a loop but how can I get away from using a fixed control name in the declaration:
Dim controlname As New Control
I can't use a string that I can manipulate the contents of for controlname because it sees it as a double declaration. I can't use an array such as Control(index) for controlname. Dim Control(maxindex) As New Control doesn't work. Dim Control(maxindex) As Control works but any assignment based on this such as Control(indexvalue).Name = "ControlName" fails. It didn't address the issue of handling the declaration of new controls in a loop with some kind of variable name for the control.
