Number of possible cases??

[Smirre]

I have senario that looks like this.

7 yes/no buttons that can be clicked indvidualy.

ex.

button 1 and 2 can be marked, or button 1 or no marks at all.

How many combinations can this be??

is it 7^2??? = 7*7 = 49 ??? or ???

You're on the right track.
Just think of each button as a position in a binary field of 7 bits.

Each click would represent a 1, and if it wasn't clicked, then it would represent a 0.
if you had only 1 button, or 1 bit, then it could have 2 total combinations.
if you had 2 buttons, or 2 bits, then it could have 4 total combinations.

so for n buttons, you would have 2^n binary combinations.

7 buttons gives you 2^7 combinations.

Would you like a list of them?

that would be nice.

how would you choose between these cases??? Should I run a select case or if statements. Each case can have 7 undercases.

Heres One way:

Dim MY_CASES(7) As Boolean
Dim CURR_STATE As Integer

Private Sub Command1_Click(Index As Integer)
MY_CASES(Index) = Not (MY_CASES(Index))
EVAL_BUTTS
End Sub
'''I was lazy, so I programmed this to build cmdDoSomething_Click
'Private Sub Command3_Click()
'Dim MyFileNum As Integer
'MyFileNum = FreeFile
'Open App.Path & "\" & "EVAL_MY_BUTTS.frm" For Append As #MyFileNum
'Print #MyFileNum, "Private Sub cmdDoSomething_Click()"
'Print #MyFileNum, "Select Case CURR_STATE"
'For i = 0 To 127
' Print #MyFileNum, Chr$(9) & "Case " & i
' Print #MyFileNum, Chr$(9) & Chr$(9) & "MsgBox " & Chr$(34) & "You are Now in State " & i & Chr$(34)
'Next i
'Print #MyFileNum, "End Select"
'Print #MyFileNum, "End Sub"
'Close #MyFileNum
'End Sub

Private Sub Form_Load()
Call EVAL_BUTTS
End Sub
Private Sub EVAL_BUTTS()
CURR_STATE = 0
For i = 0 To 6
Command1(i).Caption = i & " " & MY_CASES(i)
If MY_CASES(i) = True Then
CURR_STATE = CURR_STATE + 2 ^ i
End If
Next i
Label1.Caption = CURR_STATE
End Sub
Private Sub cmdDoSomething_Click()

Do you really have that many unique actions? You're going to
coding till the cows come home.

Normally, there are some kind of filters that can be applied:

if bit 7 is set I'm doing this no matter what else happens, if bit 6
is not set, this happens irrespective of the other things, .....
