How to test a single bit in Visual Basic?

[neoaspilet11]

Hello Everybody,

Is there a simple way to access a single bit of a byte data type in VB?

Example: a = 90 = 0x5A

how to access bit 4 of a?

Thanks,

Jack

For Byte, Integer and Long datatypes the AND OR NOT operators apply as bit operators in VB.

a = &H01
b = &H02

a And b = &H00
a Or b = &H03

(a And b) = a -> False
(a And a) = a -> True

Then when it comes to the next part of bit manupulaiton, shifting, there is no simple way to do this. Devide and Multiply with powers of 2 works for bytes but when it comes to Integers and Longs then you get into problems with the sign bit and how that is used...

Real crap that they dont have a way of working with unsigned integer and long values and also a way to do shifting.

Hello,
I think this is the possible solution.
