I have a desktop WinForms app that I would like to be able to connect to my Sql Server database that I have through my GoDaddy webhost. Problem is not all ISP's forward the 1433 port (like mine) so I can't connect directly to the DB from any of my home computers without buying the expensive dedicated IP address package, which has me thinking since my website can connect directly to the DB I was wondering if it might be possible for me to make a dll that would have all of the database interaction through subs and functions and all my WinForms app would have to do is connect to that dll through http or something, anyone know if I could do something along those lines?

I am trying to make a simple log parser that pulls info from a constant (real time updating) log file.it is CONSTANTLY being updated, and i'm having issues. [code] Basically, its messing up when its time to rescan it. I can't use the 'New' on it, as it throws a error on the stream reader.And if it's throwing an error with that, i'd be curious what other errors it will throw.The file doesnt necessarily HAVE to be deleted, but it DOES have to be cleared out. (so the program doesnt have to reparse all the lines).

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).
