Jan 29, 2012I have this code which works well:
Public Function AESEncrypt(ByVal PlainText As String, ByVal Password As String, ByVal salt As String)
Dim HashAlgorithm As String = "SHA1" 'Can be SHA1 or MD5
Dim PasswordIterations As String = 2
Dim InitialVector As String = "CanEncryption123" 'This should be a string of 16 ASCII characters.
Dim KeySize As Integer = 256 'Can be 128, 192, or 256.

What I am after is this: Rather than having a string to encrypt/decrypt, I have a byte array.

View 2 RepliesVS 2010 - Creating Library To Encrypt / Decrypt Files With AES
Sep 20, 2011I'm attempting to create a little library to encrypt and decrypt Files with AES. There are loads of examples of how to do this on the internet so coding is not a problem. There are however a few questions regarding cryptography and AES in general.
#1 Does the IV need to be kept a secret like the key ?
#2 Can I just hash a string with SHA512 to make a key for AES ? or do I need to use PasswordDeriveBytes ?
#3 In the case of me using PasswordDeriveBytes Do I need to keep the salt a secret ?(or do I need to keep it at all)
#4 Can I generate the IV from the same password that the Key is derived from ?(if so How ?)
VS 2010 Space Invaders Queries?
Oct 15, 2011I've got everything working except this one problem which I can't seem to get my head around.I've made a function that returns a random number between 1 and 11 (how many invaders there are on a row).I've managed to get this to work, however the invaders will keep firing even if they are visible, so I made a do until loop which says to keep running the random number until it finds an invader which is visible... The problem is that if the whole row of invaders aren't visible, it will get stuck in the loop.

Oct 18, 2011I'm just now starting to work on something that works 'like' an ide, where it will auto space my text as I type. I really JUST started and I'm not sure if I'm even doing it remotely like I should. anyways, what I'm doing is on TextChanged (eventually I'll just do it on newline but that can wait) it gets the contents of the text box, puts each line into a string array, trims the excess whitespace, see's if it has a keyword in it, and then adds some whitespace to it if it does.I know I'm doing something wrong with either my declarations or my error handling. Mostly because i'm not sure how to work with string arrays, can you help me with my syntax?[code]

VS 2010 : Space Invaders Alien Loops/arrays?
Oct 2, 2011Been given an assignment to create a space invaders game. Although there's a long way around, is there a way to make my code smarter.Here's the section to make a row of invaders so far:
Public Class Form1
'number of invaders in a row (horizontal)
Dim numberofinvaders As Integer = 11
'set of invaders (vertical)
[code]....
So what I want to do more precisely is have the value of setofinvaders to change how many rows of invaders vertically in a loop.
VS 2010 Tell What The Size Of My Program Is And How Much Disk Space Is Needed To Install?

Visual Studio 2010 - .net Application Works With Files Dragged Onto The Exe But Crashes If There's A Space In The File's Path?
Jun 15, 2011I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?
View 2 RepliesKeydown Space/Enter - Use The Space Or Enter Key To Change The Image In It?
Sep 8, 2011I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

View 4 RepliesAdd Controls To A Form Fails Because They Disappear
Jun 10, 2010I have an add-in that creates a form, adds controls to it, then tries to add some more. But on the second attempt to add controls, they disappear. If I have an error in my code that gets displayed in a message box I can see the new controls behind it. When I click OK they disappear. If I have no error and step through the code, they are there according to properties, although I can't see them because the form will not display while in debug mode. When the program finishes, th controls that were created are gone. Perhaps I am selecting the form to edit wrong.Too bad there isn't any documentation (or any than can be found) that describes how to do this.[code]...
