Processing Multiple Check Boxes in SQL Query

I'm having dificulty figuring out how to process multiple check boxes on a
web form.

Let's say I have three check boxes:
cbox1
cbox2
cbox3

The only way I can think of to code the possibilities is something like:

If cbox1.checked = true then
..........
End if

If cbox2.checked = true then
.......
End If

If cbox3.checked = true then
.......
End if

If cbox1.checked = true and cbox2.checked = true then
.......
end if

If cbox1.checked = true and cbox3.checked = true then
.......
end if

And the If/End IFs go on forever!

As you can see, if I have around 8 check boxes, doing it this way could lead
to tremendous amounts of coding. I'm sure there's a better, easier way,
right? I thought of using a select case but that wouldn't be much better I
don't think.

Terry in the dotnet.vb newsgroup gave this suggestion:

dim c as integer = 0
if cbox3.Checked = True then c = 1
if cbox2.Checked = True then c += 2
if cbox1.Checked = True then c+=4

Select Case c
Case 0 'No checks
Case 1 'cbox 3
Case 2 'cbox 2
Case 3 'cbox 2 & 3
Case 4 'cbox 1
Case 5 'cbox 1 & 3
Case 6 'cbox 1 & 2
Case 7 'cbox 1,2, & 3
End Select

I thought this was a great idea, but when you have 7 checkboxes, that still
leaves 128 Cases within a select case statement to program.

Is there a dynamic way to code this scenario that works with web forms?

The application is a query that runs against a single table in an access
database. Each check box represents each field they could chose from to show
up in a table or other style report.

TIA,
Jim

Hi Jim.
Try loop thru controls array or search this controls by specifc name:

for (int i = 0; i < page.Controls.C ount; i ++)
((Checkbox)Page .FindContol("ch b" + i.ToString())). Checked
or
((Checkbox)Page .Controls[i]).Checked

Of course this is just a tip ;)

Regards from Poland.

I need a button that will check (make true) two check boxes (fields) For the record that has the focus (the record on the form that I am presently looking at). The two check boxes would be like a "sold" check box and an "add to report" check box (for print out). Also as part of this button, I would like for it to enter a date into a field such as a "date sold" field. That should be fairly simple and I could probably figure out how to do...
