I have an one dimension string array ar1
ar1(0) ="One;is;a;dog;"
ar2(1)="Two;is;a;cat;"

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 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

View 20 RepliesI 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.

{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 the following array in my project that I'm trying to redim without losing the values.The problem with redim preserve is I can only redim the last dimension of the array. I want to redim the 2nd dimension without losing data. How do I get this to work?[code]
View 11 Repliesi 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?

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...

View 7 RepliesI 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)?

View 6 RepliesI 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.

My program displays nature pictures so I want to restore the original ratio on wide screens when the form is first normalised. In the form resize event (inside a flagged section to avoid looping) I have
[Code]...
For some reason the resize event is only triggered once and only the width gets set. If I change the order only the height gets set. how to make it change both?Actually I wouldn't ever need to change both if not for a small but annoying little problem on normalising. Rather than fit the available screen height it always seems to be a bit more, as if the top border height is added to the existing max height. This seems to be a .NET bug.
I would like to know if it is possible to get the dimension in pixel of a form without the title bar and the border.
View 2 RepliesUsing 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.

How do you split the 2 dimension into 2 variable from a string?

how do i split the string into 2 variables with "," as the splitting refernce point? I'm using vb08.
I'm still doing upgrades on my program that i'm creating and i've run into a bump again. I'm currently using a multi-dimension array to store a name, email, password, email provider, and user name. These 5 values are stored, corresponding with the latter, meaning the array is build as: name 1....n user name 1....n user email 1....n user email provider 1....n password 1....n So my question is, how can i store this in My.Settings? To be clearer, i'll use code: My.Settings.Name = name My.Settings.UserName = userName etc..... My current set up for a first run is like so... My.Settings.Password = adminInfo(2, 0) My.Settings.UserName = admingInfo(1, 0) etc.

The problem I'm having is while trying to find all Measure Groups that are related to a given Dimension. I've been digging through the API and it doesn't seem that Dimensions have any information on Measure Groups at all, but Measure Groups can contain Dimensions.
This makes it easy if I want to get a list of related Dimensions given a Measure Group(measureGroup.Dimensions), but what I'm looking for is the opposite.
The only thing I can think of is to loop through all the Measure Groups within the Cube and check if it contains a reference to the Dimension in question[code]...
