Convert Byte Array to Hex String (and Hex to Byte Array)
In VB6
I have a Byte array
Type PlayerBitType
bit(1 To 13) As Byte '13 bytes = 13 x 8 =104 bit values
End Type
Dim mybytearray() As PlayerBitType
I can set and clear and check these 104 bits in this array no problem
However, I need to save this byte array into an Access table as a string, and therefore need to convert mybytearray() into a string. I thought to convert to a hex string eg "FFFFFFFFFFFFFFFFFFFFFFFFF F" so that I can represent the 104 bit values as string containing 26 hex letters. (26 x bit bits = 104).
Q1. How can I convert bits in mubytearray to a hex string?
Q2. I woul dthen need to reverse th eprocess and convert the hex string back to mybyte(array).
Thanks

Thanks. That got me closer.
In the end I decided to pass a byte at a time:
Public Function Binary2HexString(ByRef mybyte As Byte) As String
Dim hexnumber As String
Dim i As Integer
Binary2HexString = ""
hexnumber = hex$(mybyte)
If Len(hexnumber$) < 2 Then hexnumber$ = "0" & hexnumber$ ' ensure it is 2 digits
Binary2HexString = hexnumber$
End Function
The more difficult aspect of converting the hex string back to binary still remains.

Function Binary2HexString(theArray as PlayerBitType) as String
Binary2HexString = ""
For I = 1 to 13
hexnumber$ = HEX$(theArray.bit(I)
if len(hexnumber$)<2 then hexnumber$ = "0" & hexnumber$ ' ensure it is 2 digits
Binary2HexString = Binary2HexString & hexnumber$
Next I
end function
