[2008] Binary To Hexadecimal (String)?

May 25, 2009

So 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!

.net - C#: UniCode To String Conversion?

Nov 15, 2010

How can I Convert a Unicode value to its equivalent string for example i have "రమెశ్" and i need a function that accepts this unicode value and returns a string I was looking at the System.Text.Encoding.Convert() function but that does not take in a Unicode value, it takes 2 encodings and a byte array. I bascially have a byte array that I need to save in a string field and then come back later and convert the string first back to a byte array. So i use ByteConverter.GetString(byteArray) to save the byte array to a string but can't get it back to a byte array.

DateTime Conversion From String?

Jun 18, 2012

I am getting this datetime format in an xml file:

2012-06-14T11:15:41.587-07:00
2012-06-14T10:49:32.397-07:00
2012-06-11T11:10:49.2-07:00

I believe I understand some of it, please correct me if I am wrong:

2012-06-14 = date

T = time identifier

10:49:32.397 = hour min second milliseconds

-07:00 = I have no idea

I need to convert this to something I can sort on for my datagrid view.

When I try something like this:

Console.WriteLine(String.Format("{0:d/M/yyyy HH:mm:ss}", "2012-06-14T10:49:32.397-07:00"))

I'm getting the original string back out with no conversion.

Compiler Conversion From String To Number

Apr 18, 2011

This is more of a curiosity question on what the VB compiler is doing. Basically the following code generates an error,
If "String" = CInt(1) Then
End If
As it should. What makes me curious is the error reported is
Conversion from string "String" to type 'Double' is not valid.
So, I guess my question is, why is the compiler attempting to convert to a Double when I would assume it should be converting to Integer?
