I have converted this parallel extension c# code sample to VB.NET
using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)
Return SendTaskCore(ping, userToken, Function(tcs) ping.SendAsync(address, tcs))saying that ping.SendAsync(address, timeout, tcs) does not produce a value
2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
I recently aqquired VB 2010 Express but have limited programming experience.I am looking for sample code and/or literature which will show me how to plot a Y=f(X) curve - for example code which will plot a straight line, a parabola, etc.I need it as a template from which I can learn about how to build such a graphing program and then tailor one to my needs.
I have a vbscript that does the following but I want to do it in vb .net and was hoping someone could post some sample code to get me started. The script does the following. Monitors 2 folders specified in a config file. When a zip file is put in the one of the folders it us automatically unzipped to a working folder and then the zip file is renamed to unzipped-<zip>.zip. I am hoping someone could post a visual studio project or code that might help me get started.

Anyone knows where I can download binary search tree for VB.Net ? I'm working on a small project for my company and I'm thinking of using BST as a sorting tool.I used to do BST using C++ and I was using linked list. I'm not sure if that can be done in VB.Net but is there any other ways? any input and comments are welcome.
I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...
Is someone can give me an example in code making in searching for telephone numbers. Im just a begginer with just a little knowledge in coding. Any simple example that can give me hints on how to start a code in searching of telephone numbers.
I know how to genrate a serial number using GUID. How can I use it. Suppose I send a CD with the software to someone. I do not want just anyone to use it. They have to have the KEY or SN. How can I impliment it so that if you do not have the s/n / key then you will not be able to install the software.
When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.

I am looking for a bit of inspiration here, a client has requested me to build a simple remote process monitoring application with capability for smtp notification, when monitored processes go down or come back on-line. Can anyone point me in the direction of some sample code to get me started. I have briefly looked at .net remoting as a potential development path, from my understanding of how this works, the remoting architecture would require both a client and remote server component, (though I am not a 100% sure on this one), however if this is the case, then it will not fit the bill, as one of the fundamental requirements is that no additional software can be deployed on the servers which are to be monitored
I'm looking for some sample .NET code that would show how to send text messages to pagers. I have no problem with sending text messages to cell phones, but could not find how to do the same for pagers.
I would like to ask something about Network in VB.NetI try to search network code sample to produce VB.Net application (Like Server and client)But I found a lot of codes (Server and client) and the codes are very complicated for me because codes are mixed with chatting process So I would like to know or want some sample Network VB.Net application(code) the application has two forms
form1(server) and form2(client)
form2(client) has (one button or textbox)
form1(server) can make visible or invisible (button or textbox) of the form2 (Like that code, I can able to make or learn other processes) I want to know how to code it. If I can get the code, I can learn more smoothly with various way
I want to create business rules that are separated from the DAL code that is generated by my L2S model. Per the NerdDinner example (which is written in C#) this code needs to be in a partial class like mine is below.

Entity Splitting: one class, two or more tables.Here is how it is done in C#, but I need to get it working in vb.net.One more thing: the class name and table columns do not match, so I have to be able to map that out, too.I have to get this to work this way because the place I'm working at right now is a vb.net only shop and the database schema is fubar, but they have so much (millions) of lines of code done directly against the database in both asp classic, vb.net, AND asp.net webforms that changing the schema right now is not realistically possible.
I created a sample ASP .NET app. I set the location to File System. When I tried to debug it I get an error message: "Internet Explorer cannot display this webpage". I was meant to understand that I can test this app. without Internet Connection. Why is it telling that?Only performance counts!
