VS 2010 Optimizing Byte Array To String Encoder
Feb 4, 2011below is a byte array to string encoder. It uses the yEnc algorithm that is used for Usenet binaries (Usenet only supports text).
Doing a performance analysis in VS2010 shows that this is the most CPU intensive part of the application.
The encoder function is used thousands of times, so I'd like to optimize it as much as possible.
I'm using 'ReDim Preserve' instead of 'Take()ToArray', because I'm targeting .NET Framework 2.0. Is there a more efficient way of getting only a part of a byte array?

'Values for yEnc Encoder
Public Structure EncoderValues

C# - Write Binary Data "as Is" To Registry (visible Binary Data As String From Regedit Only)
Feb 23, 2011I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...
I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!

Convert A String Containing A Binary, Octal And Hex Number Into A Decimal String?
Jun 7, 2009I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
VS 2010 - What Is An Integer And A String - Code An Own Sub
Mar 8, 2012Just started programming with visual basic 2010 after programming a lot with vbs (Visual Basic script) it looks a lot like each other but there are a couple of differnces so here are a couple of questions.
1. What is a integer and what is a string?
2. Can i code an own sub? so it works at all times and not only when i " do something" (press a button or something like that)
for example: if progressbar1.value = 10 then msgbox " well done" now i can only add this line when i connect it to a button or something but i want to connect it to all the lines.
3. whats wrong with this line?: WebBrowser1.Navigate [URL]

[2008] Binary To Hexadecimal (String)?
May 25, 2009So the server I am running has a database of players equipment, I am trying to write a program to see if they are hacking by comparing the item requirement with the stats the player has, to do this I need to convert the varbinary(512) column from the SQL Database too a Hexadecimal string, then from that string remove certain parts of it.
Example:This is the hexadecimal code for an item:
0x440047000028000000000000896B4685
the part I need is "4400" numbers (Position 3,4,5,6 from start) I then need to flip these backwards so it reads "0044". I then will compare this itemIDX with a list of items I have set aside that people mainly use this hack for.
So the main things I need help with, are converting varbinary(512) to hexadecimal and then making my program bring a list of accountID's up who are using the hack, here is how the databases are set out:
Account:
Contains account data ONLY
Game:
Contains the Character and Equipment DB
i need to compare the equipmentDB, then return the CharacterID from the equipmentID, compare that ID with the CharacterID in CharacterDB, then extract the accountID then return the account name from the accountDB I don't know how the binary is split up from item too item, although I would imagine, it isn't, i would have thought it just goes onto the next item when the item ends.Although, all the items start with hex string "0x" so this may be the separator!
