View 1 RepliesModule Level Variable - Array And Sort List
Mar 13, 2009I just need to know where my code is jacked -up at, I get an error when I created the module level variable ( class statement must end with a matching end class) problem is that every time I add an end class the next procedure is wrong with the same error, so what can I do to resolve this and why is this error coming up. Ultimate goal of this program is to add the invoice totals to the next element in the array each time the user clicks calculate, which displays in a message when the user clicks the exit button, also this code will sort the invoice totals in the array.

Dim SumInvoice(4) As Decimal 'Delareation of two module- level variables
Dim I As Integer = 0' the index I can use to work with this array

Array.Sort(array) - Specify A Numeral Sort Based On The First Character In The String?
Jan 29, 2009Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.
Using The Array Type .Sort Function To Sort An Array?

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.

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

View 6 Replies.net - Array.Sort() Doesn't Correctly Order Target Array
Apr 13, 2012I'm using the following code to read in a highscores file with the score written first and the player's name written to the next line, and then display the top 3 scores or fewer if there aren't 3 scores written to the file. A highscores display should have the scores sorted with the highest first so that's what this program tries to implement.
Array.sort() isn't doing a damn thing. In fact, the program's not even reversing the arrays like it should either. I've tested array.sort() this way with the names and scores arrays given explicitly and it works fine. I thought maybe it was still reading the data as string even though it's declared otherwise but it rounds off decimals when I change the array type to Integer so I'm pretty sure it's not that.
I have no idea why reading the data in from a file changes how it's sorted. My teacher didn't understand what was going on either. Does anyone know what's going on here?

View 10 RepliesC# - .net - Array.Sort And Array.BinarySearch - Culture And Globalization?
Apr 19, 2009I need to sort an array containing a list of words and search the same using binarysearch. For certain reasons, the word-list must always be sorted using the sorting-rules of "en-US" i.e. American Regional Settings. The code will run under various international Operating Systems and of course this will mean that the word-list will be sorted differently according to the local Regional Settings in use. One problem could arise on a computer/device running with Lithuanian Regional Settings. Why? Because the letter "Y" in most languages is sorted like X-Y-Z while in Lithuanian, the sort order is I-Y-J. This behavior would create havoc to my program.
[Code]...
However, in means of flexibility I believe Guffa's answer is the best one. Why? Let's use another example:In German, the letter Ö is sorted Ö-X-Z while in Swedish and Finnish, the order is X-Z-Ö. In Estonian the sort order is Z-Ö-X. Complicated, isn't it? Guffa's solution will let me force Swedish sorting-oder (changing CultureInfo) on a device running under German Regional settings. Using Comparer.DefaultInvariant with its association to English wouldn't help in this case, probably the letter Ö would end up with O. Therefore my vote will go to Guffa.
.net - Sort Generic List Based Upon A Different List?
Oct 29, 2010What 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

Additionally if there's a better way to take a text file into an array or collection I'm all ears.
Sort A Multidimensional Array?

I have profitMarginArray(29,3) <29 is actually a variable, but figured I'd put in a number for the example> and what I need is to retreive elements 0 and 3 sorted on 3 in some way shape or form. The biggest problem is element 3 isn't unique so there could be 5 that have the same value (56.34 for instance) so a sorted list is out.
The current array could look something like
Item1, .34, .75, 54.67

List.Sort Not Quite Working With Strings?
Feb 13, 2011This 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:
