Add Additional Dimension To Output Array?
Oct 6, 2010
I need to add an additional dimesion to outputArrayOfBits() in the code below which I hope conveys my intention. I need to convert a one dimensional array of 1 to n boolean (bit) values into arrays that group them by 8's so the output can be consumed by someone needing these values to be in hex format (0000 1111) = 0F How do I change the declaration of 'outputArrayOfBits and the nested control loop to achieve that?
Dim inputArrayOfBits As New BitArray(32, True) ' I can't change this.
'Create array of bytes containing what will be sent out has hex numbers 0 - F
'outputArrayOfBits(0) = (1,1,1,1,1,1,1,1) 'Hex value FF

I want to convert ar1 into ar2 which is a two dimension array
ar2(0)(0)="One";ar2(0)(1)="is";ar2(0)(2)="a";ar2(0)(3)="dog"

How do I use only one dimension of an array? What I have going on is: I have an array suit(1, 4) and rank(1, 13) to represent a deck of cards. What I want to do is take the value of the rank of the selected item in my listbox to be able to add it to the rank of other selected items in the listbox (essentially adding the players hand together).

I have an application in VBA that gives to my VB.Net dll one bi-dimensional variant. It is a an array, in which every component is a another array containing two positions.
I want to get this two-position array. When I am using VBA I can access directly the data from each position by doing:dataArray(index, 0) or dataArray(index, 1)And when I want to get the two-position array I can use:
Dim posArray as variant
posArray = dataArray(index)

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.
Dim racescores(,) As Integer = {{0, 1, 0, 3, 2},
{1, 0, 2, 0, 0},
{0, 3, 0, 1, 0},

I'm trying to return changes to array data, including redimensioned arrays, from within a function call in code similar to:
fault = MyFunction(Array1, Array2)
Public Function MyFunction(ByVal inObj1 as UserStruture(), ByVal inObj2 and Integer(,)) as String
Dim myResult as String = "Failed"
Dim tmpStruct() as UserStructure = inObj1
[Code] .....
This works fine in updating the input array 'Array1', only when the redimensioning of tmpStruct is NOT performed. After redimensioning tmpStruct, the redimensioned array is passed back successfully into 'inObj1' within the function 'MyFunction', but is not passed out of the function call; i.e.
fault = MyFunction(Array1, Array2) -
The dimension of array 'Array1' out of the function call remains as it was before the function call. However, the data change; i.e.
tmpStruct(0).Nam = "New Name"
is passed successfully out of the function call.
Why the Redim operation is not passed back out of such function calls. I would like to return changes to arrays 'Array1' and 'Array2', plus a result string from the function call if I can. Furthermore, I would also like to change the dimension of the array within the function call, if required, and return the complete redimensioned array back out of the function call.

i have used in vba 3 dimensional jagged arrays where i had up to 10000 rows. i am now transferring this to vb.net and learnt that it would be better to work with lists. the dimensions are such as (30, 10000, 30). how would i structure this by using lists?

I've managed to make some single dimension array lists but I can't figure out a multi dimension arraylist.
Here's what I'm trying to do:
I have a database (mdb) with 5 columns that I want each row to be in an array list.
In PHP what I'd typically do is:
$array[$field1] = array($field2,$field3,$field4,$field5);
How I do the same in vb.net so anytime I need to fetch an item for a specific for the row1 I could call it?
For a single dimension I could do the following, but I can't figure out how to add more fields to a single array row:
Dim tmpArrayX As New ArrayList
tmpArrayX.Add(field(0))
tmpArrayX.Add(field(1))
etc...

I retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?

I have a grid 10x10, at present is in the form of a multi-dimensional array:
my_Array(10, 10) as char
[Code]...
Additionally this shape can be in any orientation and more than 1 as in the above example.Does anyone know a quick way to do this? e.g regex?Or alternatively achieving the same result by using a different structure rather than a multi-dimentional array?

I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.

I have a gridview in my asp.net website that and I use vb for the code behind. Each time a row is bound an even called the Gridview_RowDatabound event is fired. So what I am doing is looping through all the cells in that row: [Code]
Problem is I get an error saying redim can only change the rightmost dimension. It would suit my needs to change both dimensions here as my final result will be to total each column in the array. what other method can i use if arrays don't suit this task.

I've to make a program that reads an arithmetical sentence from a textbox, e.g 12.3*34+4*5-3 and then on another textbox identify and display what is the content of the first textbox, for example taking the last ex:
If I have this input:
12.3*34+4*5-3
The output should look like this:
<number>12.3
<operator> *
<number> 34
<operator> +
[code].....
This program should only read this operators like (+,-,*,/).I'm have in mind 2 ways of doing it, one with regex and the other taking the first sentence, put it on an array, then trim it, and somehow get the values of the array and identify if it is a number or a decimal number and if it's an operator and then display it.
The difficult part or the part that i can't conceptualize is how to implement it with regex (it should be easier with a regex format than storing it on a array).I write a bit of code, I used an array to store and then to print the numbers and I used the split function to separate the math operator, but I dunno how to print the operators and the tags.
vb
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Sentencia As String = TextBox1.Text Dim i As Integer Dim arryTextBox() As String TextBox2.Clear() arryTextBox = Sentencia.Split("+", "-", "*", "/") For i = 0 To UBound(arryTextBox) Dim Array As String = arryTextBox(i)
[code].....
Btw, I also have the code to validate the input on the textbox ::wink::

I'm creating an emulator for a device to simulate wave forms. My challenge is that when I try to convert the output of the following code, I can't convert the Math.Sin's double output into byte values that lend themselves to the byte array format required by an existing graphing control as listed at bottom below. I''m not sure how to handle this when the sin function creates negative values but the byte values will need to be positive and basically 'shifted up' so that anything over 127 is negative. (0 - 255) unsigned. BitConverter.GetBytes has been suggested but THIS is the result of that attempt.

Using VB.NET .NetFramwork 3.5. This fails and strikes me as odd. Is this correct behavior:
Public Sub TestForEach()
For index As Integer = 1 To 10
Dim z As Integer
Assert.AreEqual(0, z)
z = index
Next
End Sub
I would expect z to always equal 0 as I thought the dim-ing of an integer would set the value to 0. If you run this. It fails at the second loop. For some reason z retains it's value of 1. I know I can manually initialize z to = 0, but I wanted to know if this is a bug or expected behavior.
