List + Populate + function + database + windows Forms

[Inferrd]

Someone's having a bad day (again).

I see you are calling the function popdrawschedules from your form's Load event handler. I'm wondering if you're using a 64 bit OS since exceptions occuring in the Load event handler are unfortunately swallowed while debugging under a 64bit operating system.

This line

cummList(k) = list(k) & " " & list2(k) & " " & list3(k)

will throw an exception as you can not index an empty list (you declared it as New in the previous line).

Try

cummList.add(list(k) & " " & list2(k) & " " & list3(k))

instead.

And while you're at it, add an As clause to your function's declaration

 Public Function popdrawschedules() As List(Of String)
