ahh I see now. I must of been thinking 10 in hexidecimal.

Thanks

The reason you are getting two will become obvious once you write 10 in
binary! {g} If I were in your shoes, I would stick to powers of 2. (1,
2, 4, 8, 16, etc., and, of course, zero)

I am using longs

here look at this

Private Sub CommandButton1_Click()

Dim const_One As Long
Dim const_Two As Long
Dim const_Four As Long
Dim const_Eight As Long
Dim const_Ten As Long
Dim const_Twenty As Long

const_Ten = 10
const_Two = 2

Dim lchecks As Long

lchecks = lchecks + const_Ten

If (lchecks And const_Two) = const_Two Then
MsgBox ("it failed")
Else
MsgBox ("it worked")
End If

End Sub

the result of the IF line is 2 where I think it should be 0.

Thanks

How have you declard lchecks?

It works just fine for me for types byte, long, and variant.

If lchecks is a boolean, VBA treats the assignment as setting it to
true, i.e., -1 or all bits on or &HFFFF. The result is that all tests
(lchecks and {whatever}) will be true.

So, in no case can I duplicate your problem of getting zero.

Actually it's not working like I thought

lchecks = lchecks + 2
?lchecks and 2
0

To set the bit, add the constant to lChecks

lChecks = lChecks + const_Sub

From the immediate window:

lchecks = lchecks + 4 + 8
? lchecks and 2
0
? lchecks and 4
4
? lchecks and 8
8
? lchecks and 16
0
? lchecks and 1
0

like a bitwise and,

I've definded constants const_add 1, const_sub 2, const_div 4 ,, 8
,
10 ,
20
etc

if CheckBox_Add.Value = True Then
lChecks = lChecks And const_Add
End If

If CheckBox_Sub.Value = True Then
lChecks = lChecks And const_Sub
End If


I'd like pass lChecks to a function and have that function do
something
like

if lChecks and const_add = true then
.....


It all looks ok but my lines like lChecks = lChecks And const_Add
don't
set
lChecks to anything

Thanks
