I have written a crawler in Perl awhile back and it was super simple giving the high-level capability of libwww-perl. It is so straight forward in fact, it can take the raw HTML response of one request, and create the next HTTP request for you from the FORMs on that page (as in it will parse the HTML for you).
Does anyone know any library like this on .NET or Java?
Selenium is out of question because it requires the browser to be open, which we cannot accommodate in our implementation)
I've been asked to write a Windows service in C# to periodically monitor an email inbox and insert the details of any messages received into a database table.
My instinct is to do this via POP3 and sure enough, Googling for ".NET POP3 component" produces countless (ok, 146,000) results.
Has anybody done anything similar before and can you recommend a decent component that won't break the bank (a few hundred dollars maximum)?
Would there be any benefits to using IMAP rather than POP3?
.NET provides a great library for working with SMTP for sending messages, however, there is not an implementation of a Pop3 client, or IMAP client for working with receiving e-mail from a mail host.
Does anyone know of a good component that can provide Pop, IMAP, or both support? I know that code project has implementations, but from my experience finding a "good" one is hard.
I want to do something like this
ffmpeg -i audio.mp3 -f flac - | oggenc2.exe - -o audio.ogg
i know how to do ffmpeg -i audio.mp3 -f flac using the process class in .NET but how do i pipe it to oggenc2?
Any example of how to do this (it doesnt need to be ffmpeg or oggenc2) would be fine.
Is there a .NET API available to get data from your XBox Live account?
All I'm really interested in is who's online, but messages would be cool too. And some sort of event driven notifications of user sign-on would be great, but I'll poll if need be.
I have a .net 4 application that uses a Com Dll to send SMS messages. I used TlbImp to create the interop assembly and that is what is referenced in the application.
When I try to create an instance of this class, it takes a really long time (2-5 seconds).
I ran performance profile in VS 2010 and the call that takes the longest by far is System.Activator.CreateInstance().
I am looking for tips on how to debug or gotchas with using Com Interop.
is it possible to solve conflicts on client side with sync services for ado.net?
for example, with Client Insert Server Insert, updating client's table id (on client side) , tks
I look for a free launcher or bootstrapper that checks whether the .net framework is installed, and starts my app1.exe, or app2.exe if not. Alternatively a louncher that checks for the OS version.
I have a question, which Unicode encoding to use while encoding .NET string into base64? I know strings are UTF-16 encoded on Windows, so is my way of encoding is the right one?
public static String ToBase64String(this String source) {
return Convert.ToBase64String(Encoding.Unicode.GetBytes(source));
}
As per the question title, How could I take a hex code and convert it to a .Net Color object, and do it the other way?
I googled and keep getting the same way which doesn't work.
ColorTranslator.ToHtml(renderedChart.ForeColor)
Which returns the name of the color as in 'White' instead of '#ffffff'! Doing it the other way seems to have odd results, only working some of the time...
I have Client-Server environment and developed a project for Client-Server.
I need to share a folder of my Server machine programmatically using VB.NET
Please help me.
At the last PDC (can't remember which talk it was) they gave us the information that it will be possible to share assemblies between regular .Net 4 and Silverlight 4.
Unfortunately I can't find anything on this. Was this feature dropped? What options/limitations are there?
(There are similar questions on SO but they don't say if they apply to SL3 or 4.)
Hi,
I am having some problems trying to embed Gecko or Firefox into my VB.net application - specifically when running on Vista or Windows 7. Is this possible to do? Or should I look for a different alternative?

Similar to Ubiquitous way to get the root directory an application is running in via C#, but that question seems to be related to Win Forms. How would the same be done for Web Forms?
I was using...
HttpContext.Current.Server.MapPath("~")
This works great for handling HTTP requests but seems not to work if a scheduler like Quartz.NET invokes a job (the problem I am having). The HttpContext.Current is null in that scenario since an actual HTTP request is not made.
Is there any way to implement Erlang-style light-weight processes in .NET?
I found some projects that implement Erlang messaging model (actors model). For example, Axum. But I found nothing about light-weight processes implementation. I mean multiple processes that run in a context of a single OS-thread or OS-process.
I am looking to create a VB.NET application. when the application is opened it will disable the keyboard and mouse so if you hit any keys it does nothing and you can not move the mouse. (even if currently selected window is not that of application).

Is there something similar to "wait window nowait" in Windows Forms (.NET VS2008) ?
This is a commonly used sentence in Visual FoxPro for debugging purposes and "quick and dirty" thermometers.
What is the best way to put together a "shortcut" to launch a IronRuby REPL with some .NET assemblies preloaded? I think there is a way to do this in Powershell (via Snapin or Module) and I'm looking for something similar in IronRuby.
