Here is my algorithm. It runs in O(2^(n/2)) and solves SubsetSum(1000, list-of-1000-ones) in 20 milliseconds. See the comments at the end of IVlad’s post. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace SubsetSum { class Program { static void Main(string[] args) { var ns = new List<int>(); for (int i = 0; … Read more
I understand this is quite an old thread, but I could not get the listed methods to work. Here is a simpler version of the UpdateAppSettings method (using .NET 4.0): private void UpdateAppSettings(string theKey, string theValue) { Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); if (ConfigurationManager.AppSettings.AllKeys.Contains(theKey)) { configuration.AppSettings.Settings[theKey].Value = theValue; } configuration.Save(ConfigurationSaveMode.Modified); ConfigurationManager.RefreshSection(“appSettings”); } Pretty readable and avoids … Read more
Just in case you didn’t know, there is a tool called ILMerge from MS Research that merges assemblies into one file. Also you can create Multi-file assemblies using the Assembly Linker tool. Plus to answer you original question, the problem I think is that the runtime does not know that the assembly you loaded manually … Read more
The problem is that the ContextMenu is at the root of its own visual tree, so any RelativeSource.FindAncestor bindings won’t go past the ContextMenu. One solution is to use the PlacementTarget property to set up a two-stage binding from your Label: <Label Tag=”{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={ x:Type TreeView}}}”> <Label.ContextMenu> <ContextMenu> <MenuItem Header=”Delete” Command=”{x:Static local:Commands.DeleteCommand}” CommandParameter=”{Binding … Read more
I think the best way of doing this is to always pass the object as UTC, and convert to local time on the clients. By doing so, there is a common reference point for all clients. To convert to UTC, call ToUniversalTime on the DateTime object. Then, on the clients, call ToLocalTime to get it … Read more
IEnumerable<Type> GetTypesWith<TAttribute>(bool inherit) where TAttribute: System.Attribute { return from a in AppDomain.CurrentDomain.GetAssemblies() from t in a.GetTypes() where t.IsDefined(typeof(TAttribute),inherit) select t; }
Did you see this post that I wrote as a followup to the CountingDemo: http://dotnet.agilekiwi.com/blog/2007/12/update-on-persistent-iterators.html ? Unfortunately, Microsoft have confirmed that they probably will change the compiler details (one day), in a way that is likely to cause problems. (e.g. f/when you update to the new compiler, you won’t be able to deserialise the stuff … Read more
This is cheesy, but it is the only method I have gotten to work. Create a ‘fake’ client and connect to your named pipe to move past the WaitForConnection. Works every time. Also, even Thread.Abort() did not fix this issue for me. _pipeserver.Dispose(); _pipeserver = null; using (NamedPipeClientStream npcs = new NamedPipeClientStream(“pipename”)) { npcs.Connect(100); }
How does Dapper help protect against SQL injections? It makes it really, really easy to do fully parameterized data access, without ever needing to either concatenate input. In particular, because you don’t need to jump through lots of “add parameter, set the parameter type, check for null because ADO.NET has sucky null-handling, rinse/repeat for 20 … Read more
As mentioned in the question, IEnumerable has a CopyToDataTable method: IEnumerable<DataRow> query = from order in orders.AsEnumerable() where order.Field<DateTime>(“OrderDate”) > new DateTime(2001, 8, 1) select order; // Create a table from the query. DataTable boundTable = query.CopyToDataTable<DataRow>(); Why won’t that work for you?
