void encode(char * what, unsigned int length) {
 
        int counter, x;
 
        for (counter = 4; counter >= 0; counter--) {
 
                if (counter != 4) what[0] ^= what[length-1];
                else              what[0] ^= (char)(length);
 
                for (x = 1; x < (int)length; x++) what[x] ^= what[x-1];
        }
}
 
 
 
void decode(char * what, unsigned int length) {
 
        int counter, x;
 
        for (counter = 0; counter < 5; counter++) {
 
                for (x = length-1; x > 0; x--) what[x] ^= what[x-1];
 
                if (counter != 4) what[0] ^= what[length-1];
                else              what[0] ^= (char)length;
        }
}

VB doesn't support pointers so you'll need to pass a String object rather than char*. If you're changing individual characters then you should call the ToCharArray method of the String object and then work on the elements of the resulting array. You can then create a new String when you're done. The exculsive or operator in VB is 'Xor' and it cannot be used in conjunction with an assignment like that. You need to separate the Xor and the assignment, e.g.

A = A Xor B
