How can I plus two hex number?


Dim a, b, c as string
b = Hex(11)
c = Hex(12)
a = b + c




it's not working. a is just add two b and c string together.

Thanks!

you need a function to convet hex back to decimal, refer http://vblib.virtualave.net, there is a function called HexStr2Dec in vbStrings class.



public vbStrings as new vbStrings
Dim a, b, c as string
dim d, e as byte

b = Hex(11)
c = Hex(12)
d = vbStrings.HexStr2Dec(b)
e = vbStrings.HexStr2Dec(c)
a = Hex(d + e)

I have to convert hex back to decimal, then add them together? Do you know how I could add the two hex directly?

Thanks!

try this


Dim a, b, c as string

b = Hex(11)
c = Hex(12)
e = Hex(val("&h" & b) + val("&h" & c))
