Question about Control Collection in VB.net

Hi.

I've got a form and I want to iterate through the controls on it. I've
tried:

For intCounter = 0 to Me.Controls.Count -1
' do something
next intCounter

But the Me.Controls.Count only evaluates to 5, even though there are alot
more controls on the form.

Any Ideas?

thanks,

Matt

Hi Matt,

Do the missing controls belong to the form or to other container control
(GroupBox, TabControl)? In the latter case, you need to use recursion to get
them.

Hi Carlos.

Brilliant! Yes, the missing controls were on a tab control - now fixed.

thankyou,

Matt.
