Sharing Multi-dimensional Arrays Across Different Forms In VB?
Jul 9, 2011I have a very simple 2D array, it holds a list of song titles, their genre, and their runtime. frmMain loads the array from a text file and allows me to manipulate it and boil it down to a desired (implicitly sized) playlist. i want to THEN pass that playlist array to a second form, frmPlaylist The problem i'm running into....When frmPLaylist calls the Property from frmMain I receive an error that VB cannot convert the string value to a two dimensional array. Simplified...frmPlaylist is all locked and ready to receive a 2D array, but frmMain seems to only be sending a single string variable. on frmMain

VS 2010 : Multi-dimensional Byte Array?
Mar 30, 2011I think I need a two dimensional byte array I currently have something like this:
Dim MbyteData(196608) As Byte
' Open the file that is to be loaded into a byte array
Dim oFile As System.IO.FileInfo
oFile = New System.IO.FileInfo(sFilePath)
[code]....
I now need to load several files at once (say four) so I need four arrays of 196608 bytes and I want to reference them by a number - 0 to 3, assuming the array is zero based. If I use Dim MbyteData(196608, 3) as byte or Dim MbyteData(3, 196608) as byte the syntax seems to be correct but I hit an error ("Number of indices is less than the number of dimensions of the indexed array") when I try to add the extra dimension to the stream read with something like oFileStream.Read(MbyteData(index), 0, MiByteCount).

Declaring Two Dimensional Arrays?
Feb 16, 2009I am trying to set up a number of two dimensional arrays that will be accessed from several forms in the project. I have set up a module to declare all public variables.When I declare the array (Using variables to determine the size of each dimension), when I go to run it, I get an out of index error.If I declare it them as public variables within the form, I don't get the error but then the input cannot be accessed from other forms.Am I completing incorrectly in the module or is there something else I ought to be doing.
The code within the form is
Dim Boardresult(NumBoards, Numteams) As Integer
Dim compass(NumBoards, Numteams) As Boolean
Where NumBoards and Numteams have been input and stored previously.

View 2 RepliesSaving 2-dimensional Arrays To Settings?
Jun 30, 2011I have two different 2-dimensional arrays. I assume the setting i need to save them to is a string setting, as is the cast with regular integer arrays. The first 2-d array I need to save is an integer, the second a decimal.
Let's say the settings are called my.settings.2darray1 and my.settings.2darray2
Let's also say the arrays are:

dim 2darray1(50, 99) as integer dim 2darray2(50, 99) as decimal
What would the code be to load each array and save each array?

Grasping The Concept / Context Of Two Dimensional Arrays?
Oct 29, 2010I am having difficulties grasping the concept / context of two dimensional arrays. For the assignment I am working on I am required to use radio buttons to allow a user to vote if they like or dislike an item from a combo box. The contents of the combo box have been populated through the IDE via tht item property.I understand how to set up my rows and columns, which will be, (0 to 4), (0 to 1). The trouble I am having is how to record and display the votes and have them correspond to the selected item from the combo box. Can anyone give me an example of how something like this works?

I want to re-order the array so that the higher the integer value at position 0 is, the higher it's position will be in the sortedHand(20,6) array. So as above, I'd want sortedHand(20, 6) to look like this at the end:
