Limits For Multidimensional Arrays?
Sep 24, 2011I just made a multidimensional array that was 1024 x 1024 x 1024. I get an OutOfMemory exception. What is the largest size multidimensional array that is safe to use? I'm doing this in VB.net so all .net answers are acceptable.
EDIT
When I said safe, I mean, a good size for just about any computer. What size would run smoothly on a 32bit operating system. I didn't realize that the 1024 size was 4G. I'm hoping for something a 16th of that.

Extracting Data From Multidimensional Arrays?
May 24, 2012Currently, I am working on a personal project of mine to create a Pokemon Battle Simulator, mainly because I wanted to see if I could. I have created a multidimensional array used to hold all the information needed for each Pokemon I add (Currently it is only two Pokemon) The code for this is as follows:
Public AllPOKEMON(,) As Pokemon = { _
{New Pokemon("Charizard", 6, 2, 10, 360, 293, 348, 280, 295, 328)}, _
{New Pokemon("Venusaur", 3, 5, 8, 364, 289, 328, 291, 328, 284)} _

Oct 15, 2011I'm looking for something similar to using vectors and pointers that I've used before in C++; unfortunately, it doesn't seem like there's an equivalent function in VB.net.What I have is a copy of the array behind a multi-line Rich Text Box, and I need to separate the words from each line (or element of the array) so I can analyze each one separately.In C++ I would do something like this, so I could continuously expand as needed:

View 3 RepliesWhat Class For Serializable Multidimensional Arrays
Feb 19, 2009EDIT: SI have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath). One of the functions takes a given SQLCommand object and executes it into a SQLDataReader. Now depending on the SQL command text used this may return one or many rows of one or many columns. So what is the best class for this function to return bearing in mind it needs to be serialized by the web service.

Create A Multidimensional Array That Contains Arrays Of Different Lengths?
Jan 1, 2011Is 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]]

Join Lists Or Arrays Like Outer Joining Tables In SQL?
Jun 27, 2011Basically what I'm having to do is create a program that takes a list of CaseIDs and compares them to a table on a remote SQL server. However, the table holding the CaseIDs on the remote server has nearly 120,000 records.
Currently my plan is to query all records on the remote server, save the query and the current list to tables in an Access DB file and then run an outer join to see which CaseIDs have no matching records on the remote server.
I believe this will be a much slower process than I would like. If I could load both queries into arrays or lists in VB and then compare them (therefore, not having to write 120,000 records to a DB file), it would be much faster.

I would expect the Final line should be "Final: one, two, three" but that is not the case. And if I pause and check my ArrayList (al), it shows 3 items, that all have "three" in every spot which is what the last AL I added looked like.

Jan 5, 2011Here's a sub routine that fills a data set with a table which I queried using an Inner Join statement. This output table, has all the required fields and the query works fine. However I want it like so:
If a student doesn't have a StudentPrediction.PredictedGrade Field to JOIN and it IS Empty.. Then I still would like it to display the students information just leaving the StudentPrediction.Predicted field empty.
You see I am using a ListView to display the data from when I fill the ListView, but it will only display for people who have a Predicted Grade naturally. So what steps would I need to take to ensure it displays all the information in the Student's table AND for the students who do have predictions that would also be displayed. If the student has no data on PredictedGrades then that column would be blank but the rest of the information still displayed.

View 1 RepliesVB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?
May 9, 2010In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

Passing Arrays Through Fortran Dll From App Turning To Single Element Arrays?
Feb 2, 2010I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working
