Dec 7, 2010 Replies: 78 It's occasionally useful to be able to poke around in things as arrays of bytes so this library lets you do it. It can transform arrays of primitive types to and from arrays of bytes with the "endian-ness" of the conversion specified. If you need endian-ness you will either know about it or rather quickly find out. Byte arrays can be transformed to and from a hexadecimal string representation. Strings can be transformed to and from arrays of Bytes using specified encodings and to and from arrays of Chars. An array copy method is thrown in for good measure. EDIT :- Version 1.1 posted. See post #4 for details. Download link: www.b4x.com/android/files/ByteConverter1.1.zip Last edited by a moderator: Dec 15, 2015 Click to expand...

klaus Expert Licensed User Longtime User Sep 5, 2012 #24 Have you tried to download it once again ? I had sometimes the problem and downloading again worked. If not ask Erel for the non ziped files. Best regards.

R Rafal Galewski Member Licensed User Longtime User Dec 4, 2012 #27 Decimal Yes, I would like use data as HEX or Decimal . Co:sign0085:nvert HEX to decimal
raphael75 Active Member Licensed User Longtime User Dec 13, 2012 #28 If you want to convert hexadecimal number stored as a string to a decimal number you can use following code: Code: Copy Dim Str_HexNumber As String Str_HexNumber = "FF" Dim Int_Number As Int Int_Number = Bit.ParseInt(Str_HexNumber, 16) ' => Int_Number = 255 Last edited: Dec 14, 2012

kiki78 Active Member Licensed User Longtime User Feb 12, 2013 #32 Partial conversion Dear agraham, First, many thank's for this usefull library. May you add, in future release, partial conversion of array ? For now we can do that with ArrayCopy before. But it's simpler if we can have, for example, "Sub2" with Offset and Count parameters. Best Regards

T TK Tang New Member Licensed User Longtime User Apr 8, 2013 #33 Hi, I am a new b4a user. I just downloaded ByteConverter library file and noticed it is in dll file format which I do not know how to have it recognised by B4A software. I noticed all other library files format is in xml and jar but this one is different. What should I do to get this library recognised in B4A? Thanks !

agraham Expert Licensed User Longtime User Apr 8, 2013 #36 I've just downloaded it, as have 2790 others, and it's fine. What is the name of the file you download and what size is it? It should be ByteConverter1.1.zip with a size of 11,214 bytes.

kiki78 Active Member Licensed User Longtime User Sep 19, 2013 #38 Hi agraham, Another time many thanks for all of your contribution. In future release of this library, may you add conversion from and to single primitive, not only array of primitive ? Best Regards

K kimble01 Member Licensed User Longtime User Jan 30, 2014 #39 If this is the wrong place to ask this I apologize, but I have a string of hex bytes coming over a serial connection: "68FF30303030303235" when I use ByteConverter to parse this to bytes: conv.HexToBytes("68FF30303030303235") the resulting array at position 1 contains -1! Shouldn't that be 255? Thanks for the library, it's been truly useful.

If you want to convert a byte to an integer value between 0 and 255, you can use this : Dim Int_Byte As Int Int_Byte = Bit.AND(0xff, Byte)
