• .NET Development Checking if I'm online

  Hello there! This is my 1st post here and I'd like to greet all people here and ones that are yet to come! I hope we will cooperate just fine. For start, I have a question: I'm making a project with Visual Studio .NET. It is a counter that counts time spent online. (most people in Croatia still use dial-up networking, including me) I'm doing the code in C++. I was wondering how can I check if I have connected to Internet.

• .NET Development How to lock up a file

  I am writing some C# code which processes a set of files in a source directory and then moves the files to a destination directory. The code must be able to handle a situation in which one of the files might become locked while the files are being processed. I am not concerned at this point with how to handle the exception when a particular file is locked. What I need to know is how can I lock up the file You see, I must test my code against a file that is locked up.

  I've recently been hired to overhaul a website.  It was built with .html and .asp pages as far as the design aspect, but the forms and DB connection is done in .NET. I've tried opening the website in Dreamweaver and I'm able to do site design no problem, but getting the .net code pieces imported into the dreamweaver program isn't working.  The .aspx and .ascx just won't come in.  As an example, there is a .net "login and user name" form, more or less, that I can't bring ino the Dreamweaver layout and get it to actually load/work. My company has purchased Visual Studio .NET and it should be coming in the next few days. My ...Show All
