Going loopy looping

[sluefoot]

Hi there I want to create a loop but I'm not sure how to go about it This is the contents of a file;

13
11
15
3
7
15
12
18
20
2

I have 10 check boxes and I want to check 3 of them and compare the 3 boxes to the 10 places in the file and see it they fit. The checked box counts as 1 and if the check box plus a place in the file is greater than 20 then I want an error message. e.g if I check box number 9 then there will be an error message as there is already 20 places in number 9 and if I check box number 8 then that's ok because it makes 8th place 19 The problem is all three check boxes have to be checked and if only one of them is greater than 20 when added to a place in the file then an error message will appear
Any ideas on how I might achieve this
Thanks for any replies

This sounds like a school project so I'll just give you an outline

Open the file
Read the contents into an array
You will have an index from the check box that will relate to the array.
Convert the relavant array value to integer and add 1.
If it is bigger than 20 show your error.

All these operation are simple and there are examples in MSDN
and on this website on how to do all of them.

Hi agmorgan Thanks for replying I'm stuck at a very basic part. I have 10 check boxes and after 3 are checked I have a Proceed button. Under this proceed button I have to make the algorithm but my brain is twisted. How would I know which 3 check boxes have been chosen? For instance the check boxes are called monmorn, monafternoon, tuemorn, tueafternoon etc thru friafternoon. I don't know how to get the 3 choices to go to some 'space' so I can refer to them in the Proceed procedure
Any ideas

An easier way would to make the check boxes into an array then loop through them to find which ones have been checked. HTH

Dim i as Integer
For i = 1 to 10
If chkMyArray(i).Value = 1 then 'Check box has been checked.
SelectedArray(i) = i
End if
Next i

Hey lintz That looks cool Do I call all the boxes chkMyArray in a module like this:

Gobal chkMyArray (10) As Integer


And then behind each check box I just name it chkMyArray?

Not global

If you want to make a global variable you declare it public for example

Public MyCheckBoxes(10) as Long

[JRSofty]

Long is a Long Integer Data type

I think for your prog you only need Integer I just have a habit of typeing Long when I declare an integer variable.

Ah right. Integer is 32 bits and Long is an integer but 64 bits big Wow you must be doing some huge sums in your programs

Meh, longs are more than a little useful when you are graphing trig functions... those numbers just go crazily high if you don't set bounds on the number range...

I like to use bit flags
