I am having problems accessing properties of dynamically generated
objects. Can someone please help?
In a nutshell:
My app creates an equal number of checkboxes and labels that share the
same Tag number.
The checkboxes name is a concatenation of "chkCancel" and a number that
represents the order in which they were created:
chkCancel0 (Tag = 0)
chkCancel1 (Tag = 1)
chkCancel2 (Tag = 2)
etc...

The same goes for the labels

lblLabel0 (Tag = 0)
lblLabel1 (Tag = 1)
lblLabel2 (Tag = 2)
etc...

When the label is created, its text property is given a value
(lblLabel.text = value).

What I want to do, is clear that text property when I click on the
corresponding checkbox.
I want to do it with a common sub, handler, whatever, that will work
for all checkboxes.
My problem is how to acces the label text property of a dynamically
created label.

Pseudo code:

lableTag = sender.tag
if sender.checked=true then
lblLabel(labelTag).text="" (this is the part I have trouble with)

It must be very simple for an experienced programmer, but not to
vbnewbie... and it is driving me nuts!
Thanks

I forgot to specify this is for Visual Basic 2005.

Then you're a dotnetnewbie, not a vbnewbie!

What's that? Whatever it is, it is nothing to do with "real" Visual Basic.
Whoever sold that to you needs a good "talking to"!

Sender? Tag?

Almost everybody in this newsgroup is using VB6 or lower. While you may get
a stray answer to VB.NET (including VB2003, VB2005 and VB Express which have
dropped .NET from their names) questions here, you should ask them in
newsgroups devoted exclusively to .NET programming (the languages are
different enough to warrant separate newsgroup support). Look for newsgroups
with either the word "dotnet" or "vsnet" in their name.

For the microsoft news server, try these newsgroups for Visual Basic .NET
related questions...

microsoft.public.dotnet.languages.vb
microsoft.public.dotnet.languages.vb.upgrade
microsoft.public.dotnet.languages.vb.controls
microsoft.public.dotnet.languages.vb.data

And these for more general .NET questions

microsoft.public.dotnet.general
microsoft.public.vsnet.general

Note: There are many other .NET newgroups (use the first three "fields" from
the last two as templates when searching for them), but the above ones
should get you started.

VB Label controls do not have a Text property; you must be using one of the
misnamed dotnet languages

yep, looks like it....

try asking in a group with "dotnet" in the name; this group is for VB 6.0
and earlier
VB.Net and VB 200x are Not.VB
