In VB6 I was able to accessa control like a progressbar form a different
form, for example

frm1.progressbar1.value =XXX

but now how can I do that in VB.NET

Thanks
 
There is not an 'automatic form collection' in VB.NET.

If the Progress Bar is on Form1, then when you open Form2, it needs to have
a way of finding the Open version of Form1. Just referring to Form1 does
not get a reference to the Open Form1, just to the Form1 class. (You could
have 20 open Form1's in your app)

So, Form2 would have a variable that refers to the open Form1:

Public frmWithProgressBar as Form1


Then to open Form2, Form1 would do:

Dim f as new Form2
f.frmWithProgressBar = Me
f.show


Then Form2 would reference the ProgressBar on the Form1 that opened it as:

me.frmWithProgressBar.NameOfTheProgressBarOnForm1

You could do a property on Form2, but the Public Variable is easier to begin
with.

If 'frm1' is the app's main form, then you can use the approach
described here:

If the 2nd form is a dialog that is shown from within the main form or
the form containing the progressbar, add a property to the 2nd form and
assign the progressbar to it after instantiating the 2nd form. Then you
will be able to access the progressbar from within the 2nd form.
