I have a list of instruments and I need to sort them to the following requirement.
order by:
cash
securities in alphabetical order
managed funds in alphabetical order
I have a list of instrument which has properties name and type, I've managed to sort alphabetically by name.
Instruments.Sort(Function(x, y) String.Compare(x.Name, y.Name))
Instruments.Sort((x, y) => string.Compare(x.Name, y.Name));
This program i am working needs to be sorted alphabetically but right now it just sorts by the length of the names in descending order. i think the problem is my if statement. [Code]

I created a sorter that StrCmpLogicalW / shlwapi.dll. unfortunately it causes errors on partial trust environments. I am in a really bad need of a solution that does not use 'shlwapi.dll' or StrCmpLogicalW and works in the same fashion.
Here's the sorter that causes the error.

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) + ", "
[Code] .....
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 heard about the IComparer thing but I didn't know how to implement it into my project.
I'm trying to sort a List of objects with a generic comparison.I get an exception when the property on which I'm sorting happens to be null in one of the objects.VB.NET 2.0, web.i've read several posts on this exception, and still don't get it.[code]It is true that this only happens on properties which happen to be null somewhere in the list.Sometimes I sort on other properties which happen to always be always non-null (using a different, but similar, comparison method), and this technique works just fine.I've tried to implement the CompareTo for both IComparable and IComparable(of FollowupSurvey) so I could capture this exception while debugging, but netiher actually get invoked (despite what it seems like the exception is telling me). At this point, I don't have a CompareTo in my FollowupSurvey object; thus, it's using Object's.It doesn't seem as if I can really help if the base CompareTo doesn't reutrn 0.anyone have any idea what this exception really means, and how to make sorting work properly?

View 1 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

View 1 RepliesIn 2007 I created a program that reads weather data into a listview. When a user clicks on the column header it fires off the column click event handler which calls the Sort Wrapper function. The Sort wrapper will re-order items either in ascending or descending order.
I have never been able to get negative integers to sort properly. I have created a stripped down listview program with a few numbers in the grid for testing. (see attached program zip file).When you run the program, click on the column header that says "Val" and you will see right away that the numbers do not sort correctly.
I have a lists of different custom classes and each must be sorted severals times before the algorithm is complete. For each sort I wrote a comparer. Sofar so good. Everything works. But: By now I have abou a dozen different comparers in more than one class and it is still getting more. I wonder if there is a way to limit the number by writing a new general function that can be used to sort all lists without the need for a specific comparer.Below is what I've got so far. But it does not work.
"System.Collections.Generic.List(Of ClassA)" can not be converted into "System.Collections.Generic.List(Of Object)."

I'm looking for a simple and efficient way to sort up to 60,000 strings that are 3000 chars long in reverse order and save them back out to a text file.
I originally thought of a doubly linked list, but then I realized that we aren't privileged enough to have pointers.
Is there some other way I can create an efficient linked list without pointers?
So I'm working on this school project where I'm supposed to add names and laptimes from textboxes to a list. I've got that sorted out with some help from Shaggy_Hiker (thanks!). Now what I'm trying to do is get the best laptime from the list of entries and display that in a label. I also want to sort the list by laptimes in ascending order, and I've tried the.Sort method without too much luck + all entries with a laptime over 60 min should be disqualified.
(I'm thinking of adding all of these to a seperate list which I've named feilreg, but right now all entries that doesn't meet the right criteria like empty textbox, negative laptime and so on gets saved to that list. I'd like to make it just entries over 60 min) I also can't seem to figure out why a laptime of say '32.45' won't register, it has to be with a comma like '32,45'. I've got a function in my class 'Rundetid' to format the output to two decimals maximum.
