If you want to convert hexadecimal number stored as a string to a decimal number you can use following code:
B4X:
Dim Str_HexNumber As String
Str_HexNumber = "FF"
Dim Int_Number As Int
Int_Number = Bit.ParseInt(Str_HexNumber, 16)  ' => Int_Number = 255

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

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 !

Hi Andrew,

Actually, I downloaded the attached file from the first post as that is the only one I can find in this forum.

Appreciate if you can re-send the xml/jar format files please.

Thanks..TK Tang

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

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.

A byte is shown as a value between -128 and +127, so FF (255) is shown as -1.
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)
