Sorting Number Numerically In List View?
Dec 18, 2010In 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.

VS 2008 Extracting Best Laptime And Sorting A List
Aug 22, 2011So 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.

VS 2008 Sorting A List(of Class) Using LINQ?
Apr 30, 2010I'm using the following code to sort a List(of Class) using LINQ. It works fine, but I'm wondering if there is a better way to do it. I'm basically taking one list, applying LINQ to it, then using the result to create a second list in the sorted order. Can I do this without creating a second list? Here is my sample
' KeyMatch is my Class Variable
' mMatchList is the Unsorted List

View 1 RepliesVS 2008 List View Items Flickering?
Sep 30, 2010I have a listview (details) with owner draw set to true (so i could make rows alternate in color, looks cooler) which basically contains items and subitems whose texts reflect status info that updates constantly
the problem is, sometimes (if the task runs quickly) the status changes really quickly, and as a result, listview items "flicker" for a millisecond no error, no real problem, its just really annoying and makes the program look less professional.
Is there a way to make the listview not flicker? Or maybe there is a way to make it so that the listview doesn't process too many drawsubitem calls during the same time interval? or maybe there is some customized list view out there that does the trick better?
NOTE: i tried with owner draw set to false. it flickers less, but still flickers. same problem :S
Also NOTE: i am not making cross-thread calls. i have 50 items in the listview and 4 colums, mainly the last 2 subitems change.

View 1 RepliesException When Sorting List
Jan 29, 2010I'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?
