Is it possible to dynamically add controls (speciifcally
System.Windows. Forms.ProgressB ar and System.Windows. Forms.Label) to a panel
to a form and have them display (and fucntion) at run time?
I've been trying todo this by creating arrays of progressbars and labels.
Then for each item in the root nods of a treeView that I need to track
progress on, I create a bar and label and add them to a panel. The problem is
that when I display the panel, its blank... no labels, no progress bars.
Here's a code snippet:
'pnlProgress declared above...
'x declared above...
Dim pgb(x) As System.Windows. Forms.ProgressB ar
Dim lbl(x) As System.Windows. Forms.Label
Dim tn As myTreeNode
Dim i As Integer = 0
For Each tn In Me.treeView1.No des
'Set up progress bars
pgb(i) = New System.Windows. Forms.ProgressB ar
pgb(i).Dock = DockStyle.Fill
pgb(i).Minimum = 0
pgb(i).Maximum = 100
pgb(i).Value = 50 just to test the bar
pgb(i).Visible = True
'Set up labels
lbl(i) = New System.Windows. Forms.Label
lbl(i).Text = tn.getSlideName () & " content progress"
lbl(i).Dock = DockStyle.Left
lbl(i).Visible = True
Me.pnlProgress. Controls.Add(pg b(i))
Me.pnlProgress. Controls.Add(lb l(i))
i += 1
Next
Do I have to declare all the objects as "Friend WithEvents " at the top of
the form before I begin (no longer dynamic...)
I pretty stuck on this... Is there something I'm missing? (hopefully
something simple)
Any help would be appreciated...

Hi Charles,
How's Camilla? (sorry... I couldn't help myself... :-)
OK, jokes apart, it's very easy to add controls at runtime anywhere in
dotnet. Even hooking up events to any sub or function (wich was a
nightmare in VB6).
All you have to do is simply follow the lead of the designer... Check
the code the designer generates when you add a control.
Regards,
Paulo
Forget WithEvents.
Use AddHandler obj.Event, AddressOf MethodName

Ok, so now that I know its possible - other than the erronous Dock values
below (just assume they are all docked to the top) - why isn't the code below
working for me? I modeled it after what the form designer created!

Probably are they docked each over each other.
In your situation I would first test it with docking anything

Hello,
I have a situation with MS Access 2000 in which I need to display report

you think of the report in terms of what a spreadsheet might show, the

database. The row data will also come from the same database. So in this
case, I will have a main report and a subreport. I've already tried...

I'm trying to make an app that I will use to scan in one or more than

the code I'm using for testing purposes. I've got the code in the
form's load event, but I think I'd have the same problems no matter
where the code existed. Right now, the form has an empty tab control,
everthing else is dynamic.
