clearing all the lables on a form in vb.net 2005

[be.special]

hi!
i have the following code:

for each control ni controls
dim tb as lable
if typeof ctl is lable then
tb = ctype(ctl,Lable)
tb.text = string.empty
end if
next

but in .net 2005, i can't write typeof . is there another syntax for it?

 

[be.special]

instead of
<if typeof ctl is lable then>
use:
dim tb as lable = TryCast(ctl, lable)
and ask:
If tb IsNot Nothing Then
tb.text = string.empty

Hello!

It should work. Try this:

If TypeOf (Ctl) is Label Then
...
End If

for each control ni controls

Hello!

It should work. Try this:

If TypeOf (Ctl) is Label Then
...
End If

And naturally it has to be "If TypeOf (Control) is Label" in your case.

it should work only in .net 2003 and not in 2005, and in 2005 she sould
use the second reply

In my VB 2005 Express TypeOf works fine.

You surely still can write 'TypeOf...Is'.
