Module 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.
Public Class frmInvoiceTotal
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
Private Sub btnCalculate_Click(ByVal sender As System.Object, _

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.

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?
Mar 1, 2010I am using the Array type .Sort function to sort my array.By default it places the result Array into Ascending order Least to Greatest How do I change that to Descending order Greatest to Least?and How do I change it to Closest to logic? or does that not exist?Assume there is an Array of Numbers 0,13,21,-2,4,5,1.34 and I want them to sort closest to 0 or some other arbitray value; the Output should look similar to:

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
Php - How To Produce A Different Md5 Hash With Different Encodings
Apr 1, 2011I am porting over some code from .net (vb) to php and I came across some md5 hashing that I can't reproduce in php. In the .net one there are two functions one uses UTF-8 encoding and the other uses Unicode encoding. The output is a different hash when passed in a string
// First function (returns GUID)
Dim oHasher As Cryptography.MD5 = Cryptography.MD5.Create()
Dim oEncoder As New System.Text.UTF8Encoding()
Dim csData() As Byte
[Code]...
but they both produce the same result. Is it possible to produce the same results in php with md5 hashing?
IDE :: Encodings In MX Excel 2003 And Notepad?
Jun 2, 2010We have a Windows based application whose GUI is in Unicode coding (UTF-16 I believe). But each time I copy a string from a cell of MS Excel 2003 or from Nodepad and paste it to the GUI of our application, the string can not be displayed correctly, just comes out. ( but if you type directly from the keyboard into the GUI, it's fine). I believe it is because the string from Excel or Notepad is one-byte string (maybe UTF-8, I am not sure). What is default encoding in Excel 2003? How can I make it work correctly - change the encoding in Excel or Notepad or some other way?
View 2 RepliesText Encodings In .net, Sql Server Processing?
Jan 7, 2011I have an application that gets terms from a DB to run as a list of string terms. The DB table was set up with nvarchar for that column to include all foreign characters. Now in some cases where characters like ä will come through clearly when getting the terms from the DB and even show that way in the table. When importing japanese or arabic characters, all I see are ? Now I have tried converting it using different methods, first converting it into utf8 encoding and then back and also secondly using the httputility.htmlencode which works perfectly when it is these characters but then converts quotes and other stuff which I dont need it to do. Now I accused the db designer that he needs to do something on his part but am I wrong in that the DB should display all these characters and make it easy to just query it and add to my ssearch list. If not is there a consistent way of getting all international characters to display correctly in SQL and VB.net
I know when I have read from text files I just used the Microsoft.visualbasic.textfieldparser reader tool with encoding set to utf8 and this would not be an issue.
Converting System.array To Double() Array?
Jun 12, 2012just hoping that someone may be able to assist me to convert system.array to double() array.
Declarations are as follows:
Private f_Data As System.Array
Private f_Measures() As Double
Private f_NumberOfObservations As Integer
I then 'fill' f_Data from a range in an Excel worksheet as follows:
f_Data = wsXLSData.Range(wsXLSData.Cells(1,1), wsXLSData.Cells(8, 1)).Value
This seems to work OK. Upon checking f_Data is indeed filled with 8 double type numbers.
I then try to convert this system.array to a double array as follows:
For i As Integer = 0 To f_NumberOfObservations - 1
f_Measures(i) = f_Data(i + 1, 1).value
Next
I then get an error pointing to the line ' f_Measures(i) = f_Data(i + 1, 1).value' of type MissingMemberException was unhandled by user code'

_activities is a List(Of Activity). Using VB, how would you convert a List(Of Activity) to a List(Of T) as in this code sample? The compiler doesn't like anything that I've tried thus far.

Converting A String To An Array And Then Using It As An Array?
Apr 7, 2012Okay I am working on a Voice Recognition Application that has a chat bot in it. When voice is recognized it converts the recognized string into an array and checks if the first or last value of the array is either computer or the Bot's Name. However, I am still very new to VB.NET only been programming in it for a few days. (I know ASP and VBscript really well though) When it goes through the check I get an exception how do I fix this? Here's my code with a comment on the line that it fails on:
Private Sub OnReco(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechRecognitionType, ByVal Result As ISpeechRecoResult) Handles RecoContext.Recognition
Dim recoResult As String = Result.PhraseInfo.GetText 'Create a new string, and assign the recognized text to it.

Add An Array Sort Inline?
May 6, 2012strtest() = objFile.ReadToEnd.Trim.Replace(vbCr, "").Split(vbLf).Distinct.ToArray
I created this command from a few examples which reads the text from a StreamReader, Trims, splits on EoL, and returns a unique list. My next command is a sort. I couldnt figure out how to add a sort to this command. Its really not that important but I was curious if there�s an easy way.
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
Item2, .32, .75, 57.33
Item3, .29, .5, 42
