Is there any way to for/each controls?

[Terry Olsen]

Is there any way to run through all controls on a form using a For Each
loop? Say I want to clear all textboxes on a form...what's the best way to
do that?

Terry,

There is no best way.
My sample is this one.
\\\
doset(Me)
Private Sub doSet(ByVal parentCtr As Control)
Dim ctr As Control
For Each ctr In parentCtr.Controls
'DoSomething
doSet(ctr)
Next
End Sub
///
I take the start others take the child.

Be aware that you cannot use this to delete controls.
Than you can beter use a Z order loop.

I hope this helps,

Cor

dim ctl as Control
for each ctl in Me.Controls
ctl.dispose()
