Well I'm just trying to sort array's so it would show in numeric order in the labels ... I tried the code
Array.Sort(arrayname)
Example: 55, 30, 52, 23
goes to 23, 30, 52, 55
however nothing happened when I used this code
In Visual Basic 2008 or 2010. How to sort numerically in this format:
From this:
"basketball" 900,000
"golf" 300,000
"bike" 600,000
"snow boarding" 800,000
"mountain climbing" 500,000
"roller blading" 100,000
"soccer shoes" 400,000
"football team" 700,000
"field track" 200,000
To this numerically:
"roller blading" 100,000
"field track" 200,000
"golf" 300,000
"soccer shoes" 400,000
"mountain climbing" 500,000
"bike" 600,000
"football team" 700,000
"snow boarding" 800,000
"basketball" 900,000
I would like to have a form application that I can drag n drop the words with their numbers into a Textbox1.text and have the Textbox1.text do the sorting.
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.

how can i sort too parallel arrays?

Those are the two arrays now when i try array.sort(strflavor,decamountsold) or array.sort(decamountsold,strflavor) they are not arraigned properly. I am trying to get them to sort by which flavor sold the least and which flavor sold the most. However when i sort them, the flavors are not matching up with the decimal values.
I am writing a program in which I need a particular set of buttons and labels to perform the same function... in a manner such that only the button next in order can be clicked (following which an input box pops up to offer options) I tried to define a new button and a new label object which is assigned the current label/ button.
B = Button1
L = Label1
but it doesn't work. I'm not sure if this assignment is allowing only the reference to be passed as I require (so that Button1 reflects changes when I write code for B, etc.) Also i learned that arrays of objects are no longer supported in Visual Studio 2010. Is there an alternative way to do it?.... If I could define an array of objects or something similar I think I'll be able to manage..
I have a question about efficient implementation. Lets say I have two arrays:
One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed
The other is an array of items in a particular house: Table, TV, Bed
I also have two list boxes:
1. listbox for items in the house - the "HAS" list box
2. listbox items not in the house - the "NEEDS" list box
I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS" list box. It seems to me that nested "For each" loops would be a start to solving this problem but I am not exactly sure which case needs to be nested.
I have a situation where I need to sort arrays and preserve the current key - value pairs.
For example, this array:
(0) = 4
(1) = 3
(2) = 1
(3) = 2
Needs to sort like this
(2) = 1
(3) = 2
(1) = 3
(0) = 4
Retaining the original keys. Array.Sort(myArray) sorts into the right sequence but doesn't keep the indexes. I need a variant that does.edit Using the links, this seems close to what I want. Do I just need to remove the extra brackets to convert this to vb.net?

View 5 RepliesI need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.
I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.
I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array.
I've been searching for days for a solution. I've scoured the internet and other forums and tried so many things at this point that I think my brain may explode.I receive a large XML file from a third party vendor. I have converted the XML file to a a dataset and use the dataset to fill a datagridview with a specific table. I do not have a schema from the vendor and the XML file does not contain any data type information. The datagridview populates fine but all columns are defaulted to type string. This presents a problem when sorting columns that should be numeric - they sort by string comparison instead of logically numeric. I've tried numerous ways to attempt to convert the datatable columns to integer to no avail.
[Code]...
I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?
In 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 list of strings lets say the items are like this:
item_1
item_2
item_4
item_10
item_8
item_11
If I do list.sort() I get the following
item_1
item_10
item_11
item_2
item_4
item_8
Somehow I need to get these in order numerically but I am dealing with strings not numbers.
I'm killing myself and dehydrating trying to get this array to sort.I have an array containing directories generated by;Dim Folders() As String = Directory.GetDirectories(RootPath)

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?
View 1 RepliesWell im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...
With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.
View 7 RepliesI'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working
