I have declared and array
[Code]...
I have created a SWAP function that does the swapping if the index value is greater than the index+1 value, with a loop that will iterate through the array (assuming that you dont have to specify how many iterations are required) until the array is sorted.
I have nine always changing values that are strings I need to know how to sort them. I have each of the nine values each on it's on panel. I want to make the panels stack highest value to lowest value. Shot of writing every possibility of combinations and let's say that would take forever.
View 2 RepliesI have a dynamic webpage that loads a user control multiple times, including loading the user control within itself as many times as needed. Within the user control there are four controls: Title Label, Repeater, Placeholder and within Repeater a AjaxControlToolkit Rating control.
The structure can look like the following:
Webpage
Placeholder
UserControl (repeater hidden, no data)
Placeholder - [UserControl]
[code]....
how do I efficiently loop through this type of structure to find the rating controls?

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.
I 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:
0,1.34,-2,4,5,13,21

I am working on a code that should capture the color of a pixel in a bitmap and then check if the 8 surrounding pixels have the same color. If the checked surrounding pixel HAS NOT the same color it will be ignored, otherwise if it HAS the same color, it should check for its own 8 surrounding pixels and so on.
To do that, I have created an array that starts with a single entry (the x,y coordinates of the initial pixel). So, when a pixel with the same color is found it is pushed to the end of the array. I used a for each loop supposing that VB would keep looping until the end of my array - and since it is growing, the last position of the array would be always pushed until I have not more pixels to be checked.
The problem is that VB is not respecting it, and is considering my array as if it had just 1 entry. Seems that it catch the size of the array when it enters the loop, and regardless the fact I have pushed new items to the array it doesnt keep looping it.
How can I force VB to update the end of array position while looping it? Although I think it wouldnt be necessary, here it goes the code I have so far...

I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
View 6 RepliesI'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 RepliesI 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.

I'm making a card game and I want to try and design my own card deck.
Dim X As Integer
Dim currentCard As Integer, currentCard2 As Integer
Dim RandomNumbers As New Random()
Dim NumberofCards As Integer

I started a basic vb.net class for my fall semester of high school, and although I've learned a lot, my goal since the start of the semester has been to do this. I realize there are simpler way of assigning card values than writing 52 if then statements, but I'm planning on doing other things with the statements. As you can see, my main plan of action is to generate a random number for each card, loop through the array list to make sure the random number representing that card hasn't been assigned before, use the value to select the card, and then add the randomly selected number to the array list so it won't be used again (non-repeating random numbers).
1) I'm trying to represent all the numbers with Numberlist.Item(X) and that doesn't work because either a) x represents any one number or b) x always represents only 0, which means it only checks the first number.
2) I think I've read something about using this method for generating random numbers in a loop, that it doesn't work for some reason.

I am trying to create a multi dimension array that will search each row of the array and total up the number of 0's 1's, 2's, and 3's. I believe that I need to create some sort of looping structure that will search through each row of the array.I have created a listbox that will allow the user to pick which row of the array the program will search.This is what I have created so far, but I am only just learning and I am having trouble wrapping my head around how arrays work. So I'm not sure if I am on the right path or not.

In VB6 I could set up code to loop through say 10 option buttons to check their values. The code would be something likie this:[code]But in VB .NET it seems that if I use the Controls command as above I cannot use/check the Checked property as Control does not take that as a property of Control. It seems also that I may have to use the Find property of Control as in "Controls.Find" etc.How can I do this in VB .NET? I have a very control intensive application and I must be able to easily loop through controls and check their values without writing out 10 x the code required.
