Find A Multithreading Example That Won't Show Up As Obsolete?
Aug 5, 2009
I have VB 2008 and am trying to find a multithreading example that won't show up as obsolete. (seems like most examples are releavant for vb 2005) I found an example on the back ground worker. Is this true multi threading?I am working on a project that needs to go out and get data often but still allow the user to interact with the menus and graphics.
I'd like to put the data grabbing on a timer on a seperate thread. how to make a timer and related data grabbing a seperate thread so I don't have "starts/stops" in the gui?

I guess that I'm not the first who ask this, but what is the easiest way to use threads in VB.NET? I mean, I need to download some string from a remote server and then to show that string in the GUI, so I have to use some callback function to call it in the main thread. I found different approaches for this, but all seems very difficult compared to Python where (with GTK) I used something like: gobject.idle_add(callback_function, parameters) and "callback_function" was executed in the main thread. How I do that in VB.NET?

I have VB.Net code in VS 2008 using an obsolete method, and would like to suppress the warning.Unfortunately, following the recommendation is not a good solution, because it requires using a different class, which works differently, in important ways.I'm trying to suppress the warning using System.Diagnostics.CodeAnalysis.SuppressMessage, but I don't know what to write as the parameters for the attribute, and can't find any relevant reference.
I should also say that, right-clicking on the error in the error list I don't have any 'Suppress Message' option.

I have upgraded a visual basic 2005 project to visual basic 2010 (.net framework 4.0). I want to list all obsolete functions used in this project in order to change it with newer ones. How can I treat obsolete functions warnings as errors in visual basic 2010 ms-build?

In .NET you can mark certain methods as obsolete so that developers are alerted when they attempt to use the deprecated method.
<Obsolete("Do not call this method.")> Private Sub FormerMethod()
The thing is you can only do this within classes you control. What do you do when you want your developers to avoid using certain methods on classes provided natively in .NET or by a vendor?
For example, what if you want your developer to prefer some custom extension method on DataTable rather than Select. I'd hate to have to define a custom version of the DataTable class if only to deprecate Select. That would leave us having to police whether or not the custom table was being used.

Is it possible to prevent compiler warning caused by a static factory method returning an instance of an obsolete class? For example if an instance of an obsolete class (Foo) is created through a static method (Create) a compiler warning is caused by the factory method.
<Obsolete()> _
Public Class Foo
Public Shared Function Create() As Foo
[code]....
In C# the warning could be suppressed using "#pragma warning..." but I don't think that this exists within VB.Net. Migrating to C# is not an option due to business requirements.

I'm using Microsoft.Reporting.Webforms version 10 in order to parse an RDLC file and produce a PDF. The RDLC is a simple invoice with a couple of embedded expressions. When I run the application I get an exception that a call to the obsoleted SecurityAction.RequestMinimum has been made when compiling the expressions. Is this a known bug or something I can remedy?

I have two very similar vb.net projects. Both have recently been converted from .net 1.1 to 3.5.In one, the following code gives no warnings. In the other I get a warning when I try to set the parameters of the mysql command object:
[Code]...
If I follow the instructions, and use "AddWithValue" instead, the warnings go. But I can't figure out why I don't get these messages in the first project. It seems there is something different in their configuration, but I can't figure out what. Both use the same version of mysql.data.dll. And both are configured to show warnings in the same circumstances via the project>properties>compile menu. Can anyone suggest where else to check?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I am using an Application server for calling Oracle Reports and I have a URL to call the report. When the report is called the server converts it into PDF but when report contains large data it takes a lot of time to load. I want to do in asp.net that when I call the report url it opens the PDF file and copies it into the root of my web folder. The next time when I call the URL it opens the PDF file and creates a new PDF on backend for next call. I have made this function to download file

I have a class with a background worker in it that does some tasks on a separate thread. I want to fire some events from the background worker thread to the 'main thread' of the class, so that when using this class your not obliged to go make invoke calls for every event handler your using.I'm at a loss of how to do this though. When having a similar problem in a form of usercontrol I always use Me.Invoke, but this method is not present in a class inheriting system.object.
