I am trying to split an array into a jagged array for easy manipulation, but I am having a bit of trouble with the Copy method of Array.This is what I have:
Dim masterData()() As String = New String(splitCounter.Count - 1)() {}
For i As Integer = splitCounter(0) To splitCounter.LastIndexOf(splitCounter)
Array.Copy(ServerResponse, splitCounter(i), masterData(i) = New String(), i, splitCounter(i

Does this accept multiple data types?

How can I read data from a .csv file I have opened into a variable for later use (i.e. plotting with zedgraph)? My csv file contains 100+ columns and 12000+ rows of data, with each column a different variable.
I've searched around a ton on this subject, and combined many methods I found on the net to my project but none actually do what I am required to do.
What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)

I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?

I'm working on a reporting section of code for an inventory app I'm making for my office.I call a text file, read every line into an array then populate information pages with what has been pulled from the text file.For reporting, I want to read every text file in the directory, reading each one into a multidimensional array.Thus I can call and report on each item, i.e.ItemArray(i,2) would be all systems with Windows 2008 EE..I have code that lists all files in the desired directory and counts each file, so I eventually get counts of how deep I need the first level of the jagged array to be. but not until after code execution. Basically how can I write each array of data to the jagged array.[code]But I get a null reference exception. "Use the new keyword to create an object instance".
View 8 RepliesI currently have a VB.NET dll that returns a jagged array of double. This is the declaration:
Public Function CalcMatching(ByRef dataArray1 As Object,
ByRef dataLen1 As Integer, ByRef dataArray2 As Object,
ByRef dataLen2 As Integer, ByRef matchingType As String) As Double()()
It works well inside VB.NET, but when I insert it into a VBA project, I noticed that after the execution of the funtion, while retrieving the data, the "Type mismatch' excpetion is raised inside VBA.I searched over the internet, but I could not find a delcaration of a jagged array inside VBA. is that possible? If yes, how can I do it?

I have a scenario where I am trying to generate every combination of value from a jagged array - for example..[code]So all in first array associated with all in second array.I have created my jagged array with the values but I can't work out how to iterate through it and create all variations - I can iterate, but only get each value once at present.Also on a related note this could do with working in the case of more than 2 arrays - i.e. a multiple number of arrays within the jagged array.

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.
The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use
intRuns = 0
For intRuns = 0 To intLists.GetUpperBound(0)
lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.
this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).
