Mate, I answered your original question re: interview questions in a respectful and honest manner. [See this thread: original post re: interview questions[^]]

Seems like I was incorrect in judging your reasons for the questions in the first place.

If you are for real, then really, there is no hope of you passing any interview - forget it - go dig ditches for a job.

If on the other hand you are stirring me, then I have legitimately fallen into the trap and have only myself to blame. Smile | :)

Either way, you've done your lot with me and AFAIC you can RTFM.

Go back to Programming 101. You develop a set of tests at the same time you write the code. There's even a great argument for writing the tests BEFORE you write the code it's going to test.

If a function is expects to return values between this and that, the you script your test to try input values that are inside and outside of the range of inputs that the function expects to see what its output would be. You especially try input values on the "border" of what the expected input and output limits would be.

If you function epects an input value of 0 to 99, what happens when the function gets a negative number? What happened at -1, 0, and 1? What happens at 98, 99, 100? What happens with excessively large and excessively small numbers? Is the output of the function as expected?

If you can't figure this out, toss the job application in the trash now. You're not ready...

A module is just an alternate way of declaring a NotInheritable class with only Shared members. One additional feature is that the members can be called without qualifying with the module name (unlike a shared class member).

Is there any way to access all of buttons one by one thru loop but the buttons are not in a control array.
I have almost 40 buttons on a form and i need to make some of them enable and some of them disable at runtime by checking there names. I dont want to write the long code but the buttons are not in a control array...Is there any way out of this situation.

Thanx in advance

I'd possibly re-build part of the form so that the buttons are in a control array. Much easier and the resultant code will be cleaner too.

I have got the solution of the problem....here is that for u also
Don't redesign the form rather use the following code:
Function fResetEntries(frm As Form)
Dim objObject As Object
Dim i As Long

For i = 0 To frm.Count - 1
Set objObject = frm.Controls(i)

If objObject.NAME = "cmd1" then
objObject.enabled = false
End If
Next i
End Function

Smile | :)

isn't more easier and cleaner

No, it's not. If you just looped through 40 buttons to find one, I can save you the trouble and get it down to just one line of code:

Button1.Enabled = False

You'd be much better off sticking the related buttons into a control array. Then you wouldn't have to waste all that time checking for a name. You could just do something like:

For i = 0 to 12
    SomeButtons(i).Enabled = False
Next
