Martin,
A couple of options:
1. Pass the controls into the class in the dll, either as properties of the
class or as arguments to a method. For example:
Public Class MyClass1
Public Sub DoSomething(ByVal myLabel As System.Windows.Forms.Label)
For i As Integer = 1 To 10
'
'Processing
'
'Display something in the label
myLabel.Text = i.ToString
myLabel.Refresh()
Next
End Sub
End Class
Then on a form, call the method and pass it some control, in this case a
label:
Dim mc1 As New MyClassLibrary.MyClass1
mc1.DoSomething(Label1)
2. In the class in the dll, raise an event. Handle the event on a form. For
example:
Public Class MyClass2
Public Event DidSomething(ByVal SomeValue As Integer)
Public Sub DoSomething()
For i As Integer = 1 To 10
'
'Processing
'
'Raise an event
RaiseEvent DidSomething(i)
Next
End Sub
End Class
On a form:
Private WithEvents mc2 As New MyClassLibrary2.MyClass2
Private Sub mc2_DidSomething(ByVal SomeValue As Integer) Handles
mc2.DidSomething
Label1.Text = SomeValue.ToString
Label1.Refresh()
End Sub
Then call the method and let the event handler update the label:
mc2.DoSomething()

Hi,
I recently installed that programing environment, and I'm wondering how to do
some of the things
I created a program that renames, moves, and copies file, most of the routine
are located in a DLL file that I created along with the main program, everything
work fine, but I can not get the routine running in the DLL to update a progress
bar and a label field that I would like the name of the file being processed to
appear
I checked in the help that comes with Visual Basic 2005 Express, but I can not
find how to do this
Any help would be appreciated
