I have a List(Of T) storing a list of Custom classes called Advertisement. Each advertisement contains 3 properties, Year, Make and Model. I need to sort the list By Year, then by Make and then by Model. I have a property in the Advertisement class called Vehicle which returns a formatted string with the Year Make Model like 2007 Toyota Tacoma and ive been sorting on that but its not working how I thought it would. Basically I want to sort the list by Year (decending; lowest year first) then sort by the Make and Model (in alphabetical order) Is that even possible? Here is the code ive been using.

View 8 RepliesWhat would be the fastest way to sort a list that contains a list of objects, based upon another list? An example follows:Say I have multiple lists of employees. Each individual list has a common property value, say "Department". So I have a list of employees, in one list they all have the department string value of "Sales". In another list all the objects have a department value of "Finance". These lists of employees are then contained in a list which holds them all.
I have a second list, which should drives the sort order of the employee lists. The second list simply contains a list of strings like, "Finance", "Sales", "IT" and so on. I'd like my lists of customers to be sorted in the order of "Finance", "Sales", etc.I'm using VB.NET in .NET 2.0
In an Word addin, I'm using
this.Application.ActiveDocument.Words;
to get a list of all the words in the curret document. Now when I parse this list, I found the ,, . and are also in this list. Why is Word considering these words? I also looked at the word count in the status bar and that was wrong too, as for 7 words in my document the status bar shows 9 words.
I have a label that is supposed to display a word for 5 seconds and then move down the list in a text file and display the next word.I'm oddly able to make it work in random mode, but not going down the list in order.. random would be ok if used words didn't come up again.

We have a generic List(Of Product) that must be sorted on two or more properties of the Product class.

View 3 Repliesi used the sorting method at msdn but it isnt nice. it sorts in string format like 1,11,12,2,21,23,3,31,32 etc. is there any other sorting method.
View 3 RepliesIn .NET, the Generics Lists have a sort function that accepts IComparer or Comparison. I'd like to sort just part of a list. Hopefully I can specify the start index, count of elements to sort, and a lambda function. It looks like you can only use lambda functions to do this if you're sorting the entire list. Is that right or did I miss something?

This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

I have looked, unsuccessfully, for how to sort a list of strings alpha numerically. The .Sort() method sorts it like so:

abc,abc1,abc2,abc11,abc12,abc21,abc22

View 2 RepliesI have a slightly odd problem that I think is most likely due to an act of foolishness on my part, but for the life of me I (and other members of my team) can't see it.I have an object that contains a generic list property which I would like to sort. I have written a comparer class to do this for me and I am calling it in the following way:baseObject.ListOfThings.Sort(new ThingComparer()I have debugged into my compare function and it is returning the right values.However After the sort call, the list remains unchanged. Have I missed something obvious, or is there something else I need to do.EDIT: Yes I was being a fool, and the property returning a list was recreating it from scratch each time it was accessed

Now I want to order it.
I am working on the old hangman game. I am up to a part were I have to use a sort button to alphabetically sort the letters already guessed that are showing in the list.
I have found this code:
Array.Sort(strLettersGuessed)
lblGuessed.Text = ""
For i = 0 To strLettersGuessed.Length - 1
lblGuessed.Text = lblGuessed.Text + strLettersGuessed(i) + ", "

The problem I am having is where the flow chart asks us "is the letter at counter < the letter at counter -1? In my above code I am trying to answer this with this line:
If intCounter < strLettersGuessed.Length - 1 Then
I have tried about 50 different things in place of intCounter as well as strLettersGuessed.Length -1 and nothing seems to work. Sometimes I get an error stating can't be infinite, etc or I get no error at all but the sort button doesn't work.
I have a generic list, like this:

.OrderBy(sidx + " " + sord)

Right now, for paging my populated from code list, I have:
var questionss = myquestions

DataList.UseAccessibleHeader = True
DataList.HeaderRow.TableSection = TableRowSection.TableHeader
