Maximum Size Of An Array?
Jan 13, 2010
What is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).

I need to setting the maximum size on a picture box. I thought the syntax for setting size was picturebox.MaximumSize = (Width,Height) but doesnt seem to work. Did syntax change from VB6?

I have a MDI child form with Maximize and Minimize enabled. I've defined what the maximum and minimum size of the form.
However, when the form is maximised, the windows fills up the entire MDI parent and does not seem to heed the Maximum Size I've specified.

However, when I put a try catch statement, my error message does not get displayed, only the default one.How do I make sure it gets displayed?
Try
If fuAttach.HasFile Then
Dim filename As String = fuAttach.FileName

If you can set the height of a panel at run time
Me.Panel1.Height = 3 What is the correct syntax for setting maximum size (height)? Tried this several ways and been searching. I know this is simple.
Me.Panel1.MaximumSize.Height = 512

I created a script for caching some images my program needs, so they aren't downloaded from the web everytime. But the cache folder is getting big, and it's getting big fast. It's not really the plan to have a cache of 1Gb or something like that, so I would like to create something like this to set the maximum size:
But I don't really know were to start. Sure I can create some check, and if the maximum is exceeded, remove the whole map, or the oldest files. But maybe the oldest files are the one's used the most.

My app is receiving data in blocks but I don't know what size data will be received until it is finished, unlike file reading. So my app loads the data in chunks of 1024 bytes and then stops when there is no data to read. My question is, is it possible to keep increasing the size of a byte array as the data is being received?

When you use array.length you get the size of the array and not the number of items in it.
For example:
Dim MyArray(10) as String
MyArray(0) = "Potato's"
MyArray(1) = "with"
MyArray(2) = "salt!"
MyArray.Length will return 11
How do I get the number 3? I am creating a class library so it's kinda hard to keep testing all kinds of methods until I get the right one .

I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?
vb.net
Dim BigNumber As Double = 2 ^ 1000
Dim DigitArray() As Char = BigNumber.ToString.ToCharArray
Dim Index As Integer = 0
Dim SumOfDigits As Integer = 0

Is it possible to have a UD Class that can limit how big it can grow as an array?
for example:dim var(10) as class this would throw an exception cause the class will only grow up to 5 elements.dim var(4) as class valid cause it is under the 5 element rule dim var(4, 10) as class invalid cause the 2nd dimension is above the 5 element rule. (would throw exception)

I found out that you cannot set the array size for a structure when you are making it, i.e
[Code]...
I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e
[Code]...
This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?

I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?

I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:
VB .NET
Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories)
Dim lvi As New ListViewItem
Dim fi As New FileInfo(filepath.ToString)
[code]....
It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.

I'm using extension methods based on an array and I would like to know if there is an easy way to check that array got a specify size instead of me doing a copy paste of
if array.count != 1000
throw new exception "size of the array does not match"
in about ~50 extensions
this a small sample of extensions that I use, I got WAY more
<Extension()>
Public Function IsWhite(ByVal board() As bitPiece, ByVal pos As Integer) As Boolean
Return (board(pos) And bitPiece.White) = bitPiece.White
End Function
