Game Programming :: Multi-dimensional Array Ordering
Apr 20, 2009
I have a multi-dimensional array storeHand(20,6) which stores 6 ints. The int at point 0 in each array represents a rank. So the array ends up looking like this:
(7, 0, 0, 3, 5, 7)
(6, 2, 3, 0, 6, 5)
(5, 0, 0, 0, 13, 4)
(8, 0, 0, 0, 0, 3)
(2, 0, 0, 0, 0, 1)
I want to re-order the array so that the higher the integer value at position 0 is, the higher it's position will be in the sortedHand(20,6) array. So as above, I'd want sortedHand(20, 6) to look like this at the end:

I need some advice to accomplish this, i have a datagridview with this data:
Column1 Column2
item1 3
item2 1
item1 2
item1 5
item2 3
item3 1
item1 3
I need an array with distinct values of column1 and the sum of the values in the second dimension of the array: ar(item1,13), ar(item2,4),ar(item3,1).
I don't know how many items i will have, so i don't know the correct dimension of the array...

I'm writing an application in VB.NET and face the following issue. I'm trying to create an interface that will allow the user to select their availability given a range of times and the days of the week. I want to create checkbox controls in a tabular form with two indices that I can use to refer to a certain time range and a day of the week.[code]I followed the article found here which creates and exposes a control array,however it is not multi-dimensional. Does anyone know of a similar way to dynamically generate controls and store them in a multi-dimensional array in VB.NET?

In my football sim I am trying to save all the info from a game. There are two defined dimensions to this array. The first is the number of weeks(17 always) and then the number of games per week (Number of teams /2). The plays themselves are unknown in quantity so I decided to use List of to store them. With this type of multi-dimensional array that is also a List of I am having trouble with the Get and Set properties. I have a member variable declared as:

What would be the best way to load and save a multi-dimensional array (of bytes). I've looked through streamreader tutorials but it always seems to instructions on how to save strings. I also know there's a very easy way to save a one-dimensional array, but it doesn't work on multi-dimensional ones. What should I be reading up on?

I am attempting something along the line of below mentioned code. Though it works in single dimension array. How to make it work with 2-d array?
Dim arrayord(,) As String = {ds.Tables(0).Rows(3).ItemArray, ds.Tables(0).Rows(23).ItemArray}
But it throws the following error.Error 8 Value of type '1-dimensional array of 1-dimensional array of Object' cannot be converted to '2-dimensional array of String' because '1-dimensional array of Object' is not derived from 'String'.

I am having issues assinging values to a multi-dimensional array.
I am trying to build a 2 col, unlimited row array and populate with data from a data reader.
Dim tblArry(,) As String = {}
If reader.HasRows Then
While reader.Read()
[Code].....
When I use a Jagged Array I can get this to work. The Reader portion is workig just fine, but the coding is just not clean for this problem.

I think I need a two dimensional byte array I currently have something like this:
Dim MbyteData(196608) As Byte
' Open the file that is to be loaded into a byte array
Dim oFile As System.IO.FileInfo
oFile = New System.IO.FileInfo(sFilePath)
[code]....
I now need to load several files at once (say four) so I need four arrays of 196608 bytes and I want to reference them by a number - 0 to 3, assuming the array is zero based. If I use Dim MbyteData(196608, 3) as byte or Dim MbyteData(3, 196608) as byte the syntax seems to be correct but I hit an error ("Number of indices is less than the number of dimensions of the indexed array") when I try to add the extra dimension to the stream read with something like oFileStream.Read(MbyteData(index), 0, MiByteCount).

I am trying to turn data in a text file seperated by spaces into a 2D array.
It is for a math game. The data is statistics based on the performance of the user. One line looks like this "John Doe 0 0 1 3 0 6 0 22"
I need to put the line into an array and then be able to search by name to display the results. I keep getting extra spaces in the input of the array so the data isnt where it should be. It seems that the first entry works correctly, but appended lines do not enter correctly.
Sub ResultsToFile()
Dim FILE_NAME As String = "C:\Student_Results.txt"
Dim RecordString As String = NameForm.PlayerFirstName & " " &

I'm currently trying to make a vocabulary/flash-card program so I want an array that can store multiple values per item. That way I can shuffle the "cards" (array items) while keeping the word, definition, and part of speech on the same "card". So if I where to access the array I would want to be able to do something like this:
Dim vocabList as VocabArray
vocabList(0).Word = "blah"
vocabList(0).Definition = "blah"
vocabList(1).Definition = "blah"
And then if I where to re-arrange them the properties would remain together but just in a different spot of the array.I can get really close to this using an Item Structure and declaring the variable name with () but the problem is I have to include a number with () and I need to be able to add infinite values to the array, I can't have a set number.Also I would prefer to make it like an ArrayList as it has .Add, .RemoveAt, .Insert etc. In normal Arrays there's no easy way to add, you have to resize and stuff.
Anyways here's close to what I want, but I can't have a set amount and I'd prefer the ArrayList structure so I can just have like Array.Add and then have a Item added onto the end with 3 variables on it. The only thing is that with .Add you usually put something in paranthesis after it to denote the value to add, but if I have 3 possible values then I would have to have parameters for it or something, like .Add(Word, Definition).
Structure SpecialArrayList
Public Property1 as String
Public Property2 as String

I was planning on using very similar code to the following to export to excel quickly[url]...
However, the data that I'm exporting is rather large and I find it unnecessary to grab a dataset from the sproc, convert it to a multidimensional array of objects and then export to Excel. There are two main reasons this is unnecessary. 1) It takes time to transfer that data from the dataset to the array. 2) There are then two instances of the data, one in the dataset and one in the array. Therefore, I would rather directly insert the sproc results into the array of objects and bypass the dataset altogether. I can't do this unless I know how many rows I'm getting back from the sproc in order to declare the array's size beforehand. [code]...

I have finally been stumped this semester in my Visual basic course. Mainly because I have to write a program that is started from something that I have not created. I have to create a program that will take in info from the user, then spit out the poker hand that they are holding. For instance, the user will type in 1 for ace, 2 for 2, 3 for 3......10 for 10, 11 for Jack, and then in the next column type in C for Clubs, S for Spades.. and so on. Here is the code I have been given:

I have created this code to reset my picture boxes to default locations upon form load.
my sub:
Code:
Sub reset_Alien_locations()
Dim Xlocation As Integer = 26
For segmentIndex As Integer = 0 To AlienArray.Length - 114
[Code]...
I have this sub load up upon form_load event. Yet it doesn't do a thing! I want each picture box to appear on the same row, hence the y axis is set to 49. but I want my X-axis to be added by 30, so that there is a gap of 30 pixels between each picture box, hence the x point is: Xlocation = Xlocation + 30

Im working on a roguelike console RPG. For those of you that dont know, just google search it.What I need help with is that I have an string array called ArrMap(0 to 19) that holds the 20 rows of each map for display. I also have an array of the same size called VisibleMap that needs to hold which portions of the map are visible and which arent so that when the player switches screens [IE goes from map, to inventory] they can go back to the map and it will look the same. I was thinking of using an array, but if you can think of another way to do it, that's fine.Here are the subs that deal with the map reading and display, so you know how I have things set up at the moment.
Code:
Public Sub ReadMap(ByVal location As String)
Dim ioFile As New StreamReader(location)
Dim ioLine As String
Dim intX As Integer

I decided to take up the task of writing an app for Dungeons and Dragons. I play with my friends and I'm trying to make it a little bit easier.Before every round of combat players roll dice for Initiative. It basically tells the games manager who goes first and in what order the rest of the players go. When players roll for initiative they roll 20 sided dice. On Form1 I have a button that says "Initiative" which opens another window where the manager would type in each players values. Then I want the program to take those values and order the players from highest to lowest in a list on Form1. Kind of like...

I have created a scrabble game that generates random letters. For the user to type in a word using the random letters they have to type it in a text box.
I want my program to prevent users from typing in letters that are not provided in the text box and to allow them to type in the random letters that are provided.

I'm trying to make a simple fruit machine game for windows mobile device.
I can create the game easily enough and flip through pictures in a picture box to display the correct symbol.. but what I'd like to do is do a proper spinning reel, but have no idea where to even start.
What I have is a list of images in an imagelist (or individual files) - what I'd like is them attached to each other and moving downwards, preferably as though it were going around a drum but just them moving would be a start.
