i have a problem guys,i have a project and i really don't know how to convert

octal to binary
hex to binary
dec to binary using VB 2010..
i really need your help guys who knows the codes for this,i think its loop but i'm a newbie in any kinds of VB..our teacher didn't teach us how to do this so i'm counting on you guys who are expert in programming..i try to search in the internet but still i didn't find the codes..please help me guys,i only have 3 days left to pass my project..:(:(:( please help guys...
 
I will give you a hand but will not write the code for you...

Let's take an easy example.

255 we all know that translates into 1111 1111 and FF but why?

255 / 2 = 127 rest 1
127/ 2 = 63 rest 1
63 / 2 = 31 rest 1
31 / 2 = 15 rest 1
15 / 2 = 7 rest 1
7 / 2 = 3 rest 1
3 / 2 = 1 rest 1
1 / 2 = 0 rest 1

Easy?

This works for every other system you can up with

255 / 16 = 15 rest 15 = F
15 / 16 = 0 rest 15 = F

255 / 8 = 31 rest 7
31 / 8 = 3 rest 7
7 / 8 = 3 rest 3

Just remember to add the results from back to front. It makes sense as you do that for decimal numbers too so the octal of 255 is 377 not 773

Now the inverse should be easy too

377 octal

7 * 1 = 7
7 * 8 = 56
3 * 8 * 8= 192
7 + 56 + 192 = 255

note that the sequence of numbers I multiply with is

8 ^ 0 = 1
8 ^ 1 = 8
8 ^ 2 = 8 * 8 = 64

that counts for binary too

2 ^ 0 = 1
2 ^ 1 = 2
2 ^ 2 = 4
2 ^ 3 = 8
2 ^ 4 = 16

and for hexadecimal

16 ^ 0 = 1
16 ^ 1 = 16
16 ^ 2 = 255

We start here with the last char and not the first.
