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

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()
