Adding a leading 0 to incoming HEX data for conversion to binary

Sme1986:
Hi Paul!
Ok, then - how do I get the whole CAN Message converted to Binary with the leading zeros?
So:

A7 03 B4 9D 00 BB 07 7D

Should be

10100111000000111011010010011101000000001011101100000111011111101

But my question is, what are you doing with the string 10100111000000111011010010011101000000001011101100000111011111101?
