Mar 14, 2011In VB6 there is a feature called Control Arrays, where you name controls the same name and provide them an index value. This allows you to set a value by looping through the controls and setting each value. In VB .NET I can't create a control array?
View 6 RepliesCreate A Dynamic Jagged Arrays
Sep 25, 2010I'm trying to create a dynamic jagged array. That is, one that i can increase the size of at runtime. Maybe its easier if I show you. I have a folder containing a varied number of files. What I want to do is set up a jagged array, with the file contents as the second array. So kind of like this:
Code:
FileList(0)
Filelist (0) (0) = Line1
Filelist (0) (1) = Line2
Filelist (0) (2) = Line3
[CODE]...
However, it throws a System.NullReferenceExeption when I try that. In addition, I don't understand jagged arrays all that well....Here is my code (that doesn't work). The jagged array must be accessible by other methods.
Code:
Imports System.IO
Public Class Form1
Public Skills()()

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]]
Create A Tic-tac-toe Game But None Of The Tic-tac-toe Tutorials Use 2 Dimensional Arrays
Mar 14, 2010I am new to VB, trying to create a tic-tac-toe game but none of the tic-tac-toe tutorials use 2 dimensional arrays. Since tic-tac toe is 3x3 I created 9 buttons and want either an X or an O to appear depending on where the user clicks. I want one set of instructions to handle the multiple buttons. I was told to use Case statements.
This is what I have so far. Not sure how much is right but hopefully it gives you an idea of what I am looking for.

View 3 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

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays
Jul 25, 2012I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand
