So I have a function that looks up values in a jagged array, and it goes like this:
Private Function Lookup(ByVal Search_path As String) As Integer
Dim i As Integer = 0
Do Until MasterIndex(i) Is Nothing 'throws an exception here
[Code]....
Problem is, when I test this with an empty array, it gives me the error of Index was outside the bounds of the array at line 3. How do I fix this?
Can we make function which return jagged array? If so, could u give example of it?
View 2 RepliesI'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).
Function PushButton()
Dim intRuns As Integer
Dim intLists(2000)() As Integer[code]...............
I previously posted a Question about code that uses a function to return the frequency of characters in an array. I have now got this code.
View 5 RepliesI have been trying to write code that asks the user for the size of an array , and then takes inputs from the array. They are characters A-E... Then I am to call a function that will count the frequency of A,B,C,D,E . Then it is supposed to send the information to a listbox. Eg. There are 2 A's,There are 0 B's, There are 5 C's..
I have the code for populating the array, but when it comes to searching it for the frequencies..This is what i have so far..

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 need to scan database and insert its values into an array. But I'm having some difficulties in handling null values and array.

Every code I've tried result in error everytime I tried to insert null value into any kind of c=variable, including array which I want to use. And I'm not quite sure with what I'm doing in jagged array I want to build.

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.
