[2005] Multi-Dimensional Array/Item Structure?

Mar 9, 2009

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

Remove Item From Multi-Dimensional ArrayList By Query?

Sep 30, 2011

I am looking to remove an element from an ArrayList using a query, E.g. DELETE FROM arraylist WHERE (0) = "User1" (Where (0) is the index of the second dimension).

Code:

Dim Users As New ArrayList
Users.Add({"User0", "Details"})
Users.Add({"User1", "Details"})
Users.Remove("User1")

The reason I am looking for a query way to do this is because I will not know what the second dimension value will be.

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...

VS 2010 : Multi-dimensional Byte Array?

Mar 30, 2011

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).

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:

Lines In A Text File To Multi-Dimensional Array

Dec 12, 2009

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.

Import Directly To A Multi-dimensional Array Of Objects From SPROC?

Jun 19, 2011

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]...

VS 2005 Declare Size Of Array In Structure

Dec 11, 2009

I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.

In VB.net: Code:

So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?

VS 2008 Copy One Dimensional Array Into Two Dimensional Array?

Feb 17, 2010

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.

I can get each line into a one dimensional array using Split(Var, Chr(10)).

I'd like to make it a two dimensional array where the second dimension contains each comma separated value.

I've got

Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String

Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.

For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter

But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.

The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?
