| have you tried to take the decimal number and manually convert it to hex yourself? like if the number is 255, divide first by 16 and you should get 15, which is F and then you take the remainder of what's left (which is 15) and divide by 16 again to get another f. So, i guess in VB that would be something similar to the following: Dim n as Integer Dim upper as String Dim lower as String Dim readByte as String n = readValue() upper = n / 16 lower = upper mod 16 select case upper case 10: upper = "a" case 11: upper = "b" case 12: upper = "c" case 13: upper = "d" case 14: upper = "e" case 15: upper = "f" end select select case lower case 10: lower = "a" case 11: lower = "b" case 12: lower = "c" case 13: lower = "d" case 14: lower = "e" case 15: lower = "f" end select readByte = upper & lower so, you can make the above code into a function that returns a hex string when given a integer number assuming it is between 0 and 255 (edited by neotransotaku on 08-27-04 03:42 AM) |

| Hex(number) returns the hex version of a number as a string. It has a bit of trouble with negatives, though. | |||

| Well, if he is reading from a file, then he will never run into a negative value except for end of file, which is typically -1. As for negatives, it doesn't have trouble with it. It is more of people have trouble with it. Because if they put in -1 and get out 0xFFFF FFFF, that is expected because -1 in computer binary is 0xFFFF FFFF. |
