elegant method to check if any of a set of strings are empty or not?

[CADTenchy]

I have a set of comboxes for the user to input or select some text.
At processing time it's OK for these comboboxes to be either empty or contain something, as long as they are all same state.
They either all are empty, or they all have some text.

I can access the comboboxes' text property by an array (thanks Aaron!), so I could run through each one in a for to loop and test with an if statement and a flag or two, or use a couple of enormous multi conditional if 's, but I was wondering is there is a smarter neater way?

That'd be the way I'd do it. Use a while loop, though, and break out of it if you find a condition contrary to your requirement (text if all empty or no text if all full).

Yes a loop using controls collection...
---
for i := 0 to ControlCount-1 do
if Controls is TComboBox then
if (Controls as TComboBox).Text <> / = '' then
---
Hope this helps,
