I'm developing an "offline" application for a local government that will be used to collect sensitive information. The application will sync back up to the mothership periodically, but it will generally be used offline. It'll be running on Windows, written in .NET/WPF. I'll need a small "local" database, so I'm looking at SQLite. I c...
I'm looking to build a control that essentially abstracts a ScriptManager. I need it to look/feel just like as close to a regular ScriptManager as possible. The reason for this is so we can use an "#if not DEBUG" statement to dynamically load the .js files in CompositeScript for release, but also maintain easy debugging in our dev envir...

In .NET (at least <=2) there's a problem serializing objects that raise events when those events are handled by a non-serializable object (like a Windows Form). Because of the way VB.NET implements events, when you serialize an object, its events get serialized too (because events are actually implemented using hidden multicast delegate...

We have C++ applications that run each morning to see if the user's copy of the application is out of date, and if so, we pull down the new MSI and install it. If the application is running, we need to take it down so we can perform the update. Ou...

Does anyone have any idea when Microsoft might be dropping another Silverlight 4 public release? As ScottGu has been quoted many times: "We will be adding VS 2010 RC support for SL4 with the next public Silverlight 4 drop." I've read speculation that there might not even be another Silverlight 4 public release until RTW. It's painful...
I am building an application and I want to batch multiple queries into a single round-trip to the database. For example, lets say a single page needs to display a list of users, a list of groups and a list of permissions. So I have stored procs (or just simple sql commands like "select * from Users"), and I want to execute three of the...

Commands are missing, panes never stay where I want them, etc. Whenever I install VS, I usually select the Web Developer settings when the first time dialog comes up. I'm pretty happy with the la...

I feel like I should know the answer to this, but I'm going to ask anyway just in case I'm making a potentially catastrophic mistake. The following code executes as expected with no errors/exceptions: static void Main(string[] args) { ManualResetEvent flag = new ManualResetEvent(false); ThreadPool.QueueUserWorkItem(s => { ...

I'm working on a plugin system. Some plugins need user input. I would like them to be able to report to the main application what input they need and have the main application decide how to get it. It seems like there might be some kind of library designed for specifying options like this. So like the plugin could return some kind of Opt...
We have a rather complicated system of permission handling in our (ASP.NET web) application. Users can have specific permissions on different kinds of objects, some permissions are even packed into groups / roles that are assigned to users. All in all this ends up in a pretty complicated mess where for determining whether a user can do /...
