I 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.

Is there a way for a event to generate 12 random numbers between a negative and positive integer (ex. -5 to 5) and apply each of them to an individual declared variable, to then be used in another event?

how to generate a list of numbers, from 1 to 10 in a random fashion but with no numbers repeating. For example, every time the code is run, it will return an array of numbers, each different, only using numbers from one to ten?
This may sound confusing, so i will try and explain what I am trying to do with it. I have a form that displays 10 questions and each time a user moves to a new question, i want to display a new picture. the pictures will be named "picture1" through "picture10". I want the order that the pictures are displayed to be different every time.

I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.

I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...
This is all running on Visual Studio 2010

Im not too experienced with VB so this question will probably be fairly easy to answer. Im trying to take a 4 character value from a textbox and make sure it meets these specifications: 1st digit = and F OR P, 2nd and 3rd digit any A-Z value, and the 3rd Digit a 1 OR 2. Whats wrong with this?
part1ID = idTextBox.Text.Substring(0)
part2ID = idTextBox.Text.Substring(1, 2)
part3ID = idTextBox.Text.Substring(3)
If part1ID Like "[FP]" AndAlso part2ID Like "[A-Z]" _
AndAlso part3ID Like "[12]" Then

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

came across this issue while converting a for loop in C# to VB.net I realized that the increment operators are not available in vb.net (++ and --)whereas i was able it do something like cnt +=1 .In VB, a STATEMENT cannot be just an EXPRESSION. why this doesn't work in the same way as it does in C#.
