I have two arrays
a={a,b,c,d}
b={1,2,3,4}
now I want to create a 3rd array which should at least contains one numeric number and rest of alphabets, this code will generate unique usernames so it should not repeat the pattern of selection which is present in main array[code]...
Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python).
Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case?
e.g The above code would create an array like this:
[[0,0],[0,0]]
but would it be possible to create this:
[[0,0],[0,0,0]]

View 10 RepliesTrying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

I want to create an array of constant variables for my program. But from everything I read about arrays they are handled by a number. I want to be able to pass back a variable that will hold the name of the constant as well as the value. How would you go about do that.I want to when I type the variable to have the constant name show up as I am typing.

Supposed that I have two arrays:
Dim RoomName() As String = {(RoomA), (RoomB), (RoomC), (RoomD), (RoomE)}
Dim RoomType() As Integer = {1, 2, 2, 2, 1}
I want to get a value from the "RoomName" array based on a criteria of "RoomType" array. For example, I want to get a "RoomName" with "RoomType = 2", so the algorithm should randomize the index of the array that the "RoomType" is "2", and get a single value range from index "1-3" only.
This is a school project, supposed to be a beggining VB.Net class. I'm having difficulty with one section, sorting the array is OK but I need to only return a 3 of it. I had it working when I was selecting single files but when I went to selecting multiple files at once the formula stopped working for me. I'm retuning the array just fine but the select a 3rd seems to just pass by without being acted upon. I've been working on this a long time and don't know where to look for an answer. Here is what I have for the sort method;
Private Sub sort()
Dim Count As Integer
Dim count2 As Integer

View 2 RepliesI have an array for all 26 chars of the alphabet as a boolean. What I want to end up doing is have the program take the user's guess char and set the corresponding number in the array to true. I'm new to arrays and I have no clue how to begin doing this. this is how I am declaring my array. I am declaring the array as a char for now because I don't know how to go about using a boolean array for my game, but it seems like it would be the best way to do it. [Code]

View 2 RepliesA project requires to allocate a varying number of byte arrays (buffers).
It would be ideal if the following definition would be possible:
Dim ArrayOfBuffers() as buffer(10000) as Byte
The byte arrays must be ordered sequentially because they have to be written to a file by efficient procedures destinationFile.Write(ArrayOfBuffer(3),1000,1000)
The number of buffers will change during program execution sometimes. Therefore it would be nice to be able to do a ReDim on the data structure when needed.
This does not compile. Dim Tom As New List(Of String) = {"Tom", "Tom2"} This does Dim Tom As String() = {"Tom", "Tom2"} IMO this features should be allowed for all collection types and not only arrays.
View 2 RepliesI am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?

What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()

What is the best method to have the end user populate an array? I am doing this as a windows form. Have multiple text boxes that they have to fill out? Set the elements of the array to the text box values? And how to swap the contents at run time is something I am not sure of. Isn't there a Array Swap function or something?
