Visual C# Intermediate programer
I was wondering if anyone knows of a site to help transition beginer programers into the more intermediate programing level Although there are some good comments in this thread and some great books mentioned, it's difficult to answer without a solid understanding of your skills. In my experience, the best way to advance your software development skills is to find a good mentor who can talk with you, look at your work, and help you focus on key areas of improvement and your mentor may recommend some references to improve your work. I'm biased from leading large projects but I don't see too many people get better in a vacuum - code revi ...Show All

Windows Forms files location
This is for a windows.forms application that supports multiple users. Here each user's personal preferences are to be stored within their own "user folder" ( C:\Documents and Settings\%user%\somewhere ) is what i had in mind. I noticed that most big software companies use a certain "application data" folder within each user's section. Preferrably this software should follow the practice - but so far I haven't seen any "special folder" available for application settings. Therefore the only option left would be to hard code the string "application data" Here's wondering if it would be wise to ...Show All

.NET Development IP Address of Win Client
Is there a way to determine what ip address will be used by a TcpClient In the old .Net to get the IP address some people would use: 1. IPHostEntry hostInfo = Dns .GetHostByName( Dns .GetHostName()); Which is really bad because it's the DNS info not the real machine info or the IP being used. or 2. from WMI (if installed) SelectQuery NAQuery = new SelectQuery ("select * from Win32_NetworkAdapter"); ManagementObjectSearcher NASearcher = new ManagementObjectSearcher (NAQuery); Must guess which one will be used if yo ...Show All

Visual Basic Scrolling Text
Hi There, Unfortunately another vb beginner for you guys here.

Visual Studio 2008 (Pre-release) Skin Progress Bars?
Is it possible to skin the ProgressBar control That is, modify the default green dots to display another image, modify the number of intermediate dots it displays, modify the border to a different image, etc. Hi Derek By changing the ControlTemplate for the progress bar you can achieve any customization you wish. You probably don't want to create a whole new template from scratch though, so you can extract the current default template for that control and then customize that. I tried to document the process of extracting the control template here: http://learnwpf.com/Posts/Post.aspx postId=a3e4319b-b790-40b ...Show All
