how do i do bubble sorting with numbers?
View 1 RepliesI have an Access table which has a Number field and a Text field.I can run a query like this:
SELECT * FROM Table ORDER BY intID ASC
//outputs 1,2,3,10
But when I try to run the same query through the .NET OleDB client, like this:[code]......I get items in the order 1,10,2,3.What's going on here, and how can I have the data sort "naturally" (1,2,3,10) in both places?
I need to sort three numbers that are entered in three different textboxes and display these numbers ascending and when I press a different button display them descending. Now I think that I need to put these three numbers into an array, sort and display, but I'm not really too proficient in code to accomplish this. Is there a way to do this without putting them into an Array.Which is not much of anything so far.[code]
View 13 RepliesLets say I have the following String Array:

I have a datagridview with a column called "Total Price". This is set to a string value type because I need to always show 2 decimals. For example:
4,3
must be in the datagridviewcolumn:
4,30
So I use string.format for this. However, now I have a problem with sorting because the column is a string value type and numbers get sorted like this:
50
4000
40
300
30
20
10000

How to override the sort method or something that is called when a user clicks on the column header and the most effective way to sort it programmatically?
I have 20 textboxes. each contains a particular number . I want the textbox1 to textboxN to have the numbers in the descending order. If any of the textbox has a zero value then I want to leave that textbox as it is. A sample code in vb.net needed.
View 2 RepliesI'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference
can someone give a example of doing bubble sorting with numbers the simplest way if possible.all i know is that it uses a boolean to stop sorting, a variable which records how many swaps are done in a run if its 0 it stops swapping but other than that i dont know how to write a program doing bubble sorting?
my teacher didnt give me any examples of bubble sorting other than a algorithm, and before u ask no its not for homework i am looking bck at my computing notes and i just dont understand any of it!
if u could explain it to me step by step and give a simple brief exmaple using numbers

if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36
it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.
I 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 have problem with Sorting ListBox in Visual Basic 2008. When I load names from some files (file's name is number_name like="156_blabla") and I need sort it by that number
It is:

102_name2
1026_name3
And I need it:
102_name2
1018_name1
1026_name3
I am trying to sort text (File name and path), by having a listbox with just file name and and a datagridview with two columns filename and path.
The listbox sorts it differently from the datagridview. Mainly this is where there is a ' ie listbox puts "you're" before "you are" where the datagridview puts "you are" before "you're".
I thought I would just sort using datagridview and then read from datagrid and add to a non sorting listbox, but this did not work although the datagridview shows sorted, when you go through and a loop, reading each row to add to listbox they end up the same order they where originally put into the datagridview befrore sorting.
What I want is a sorted list of file names only, which will be obtained from several folders and then when clicked with be able to extract the complete path and filename.
I have code with a listbox and datagridview which works ok if I remove any files with ' in them.

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-

View 7 RepliesI am suppose to write a program using if statements and loops: Create an application that reads an integer number from the user and then displays in the List Box all prime numbers (for this project we are going to violate "positive" rule and make our prime numbers be negative as well) between user's number and zero 5 numbers in one row. The application also displays how many prime numbers there are between user's number and zero, and the total sum of all these prime numbers.
