Convert Base64-encoded Text To Hexadecimal?

Dec 19, 2011

I have come across some Base64 conversion functions in .net(FromBase64.string etc). What i want is, for a sample, i have a base 64 encoded string as

"48YwojCi4yaiow==".

I need to convert this string to the corresponding Hexadecimal text(The sample stands for "Thisistest" in hex text) The below link is an online converter from base64 to hexadecimal text. If you give the same base64 encoded data in the link , click on convert, the one that is seen below "Hexadecimal text" is what I need.

Is there a standard library function in vb.net which does this? Converting a base 64 data to a hexadecimal text?

[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!

Convert 1-Dim String Array To String?

Jun 21, 2010

I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.

The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.

The way I originally intended to do this was like this:

If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If

The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.

A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.
