I am trying to use a DLL that has a public class called FileCleanUp..Inside this class is a procedure called ProcessFiles as shown [code] In VB.Net how do I access the ProcessFiles events so I can inform the user on progress etc from my VB.net application that calls this DLL.By using Reflector have found that the DLL uses the Background Worker if this is of help.

how to declare "smsport" on class smscomms as public so that it can be access in class form1 or button1_click event.
I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...

I want to created a nested class that can only be visible to and instantiated from the parent class.But I also want to be able to use an instance of the nested class through a public variable of the parent class.I tried making the nested class private, or making the nested class' constructor private, but it won't compile.Is it possible to do this in .NET?

I have a base class called PageBase and then a derived class TestPage that inherits from PageBase. In PageBase I have overridden the OnInit() and when it is called and I inspect the value of 'Me', it is of the type of the derived class and not the base class. My question is how does inheritance really work? For instance, when instantiating TestPage does an instance of PageBase get created too?
Here is my code;
Partial Public Class TestPage
Inherits PageBase
Public Sub New()

View 2 RepliesHow do I force the Visual Studio compiler to generate an error when a required method is not being called in the constructor of a child class?

I am making a program where there is a number of strings are needs and they need to be pre-defined. I rather not store it all in a XML file as I don't want anyone going in and altering them.
Has anyone ever created a class of public constants just to make cleaner code or is it considered bad practice?
I've tried searching... a lot for the answer, but as I'm not too sure what exactly I'm trying to do I can't seem to find anything.

I've an app that starts to work from a module wich should load a form an do other things with a class library who raise an event an the form shoud cath it.The problem is that applicarion.run(frmMain) displays the form in the same thread the the code stops work while the form is open. And I need that the app works in this way because the user need to send files to the app using args and this avoid that the app init another instance of it (in other code) and update the form with the info when the event is raised.[code]
