• Make Visual Studios "Add Service Reference" Feature use an existing Class

  - by gencha

  When I add a service reference to my Visual Studio 2010 C# project, a new class for one of the types defined in the WSDL will be generated. A de-facto equivalent definition of that type already exists in our solution in a different assembly. When adding the SoapTypeAttribute to the existing class and replacing the references to the generated class in the generated code, everything runs perfectly and as expected. How would I tell Visual Studio to use the existing class in the generated code?

  - by 66

  I have noticed that it has solutions for matching multiple words in a given text, such as below: http://stackoverflow.com/questions/1099985/algorithm-for-multiple-word-matching-in-text If I want to know exactly the number of appearances of each matched word in the text, my solution is like this: step 1: using ac-algorithm to obtain the maching words; step 2: count the number of each word obtained in step 1 is there a faster way?

• Are Maybes a good pattern for scala?

  - by Fred Haslam

  For a while I have been struggling to integrate scala with java methods that might return null. I came up with the following utility which helps a lot: // produce an Option, nulls become None object Maybe { def apply[T](t:T) = if (t==null) None else Some(t) } Maybe(javaClass.getResultCouldBeNull()).map( result => doSomeWork(result) ) I have a few questions about this solution: Is there a better or more standard pattern to use? Am I duplicating something that already exists? Does this functionality have hidden gotchas?

• Java - How to set focus the already running application ?

  - by Brad

  I am using a ServerSocket port to run one instance only of my Java Swing application, so if a user tries to open another instance of the program, i show him a warning that "Another instance is already open". This works fine, but instead of showing this message i want to set focus on the running application itself, like some programs does (MSN Messenger), even if it was minimized. Is there a solution for this for various operating systems ?

• Using of ApplicationSettings in markup code

  - by Dirk

  I want to use ApplicationSettings in the markup code of an ASP.NET Web Application. Inspired by code behind this was my first try: <%= My.Settings.MyApplicationSetting %> No success.

• ASP.NET - Storing SQL Queries in Global Resource File?

  - by Arthur Chaparyan

  Is it a good idea to store my SQL queries in a global resource file instead of having it in my codebehind? I know stored procedures would be a better solution but I don't have that luxury on this project. I don't want queries all over my pages and thought a central repository would be a better idea.

• Can you reverse order a string in one line with LINQ or a LAMBDA expression

  - by Student for Life

  Not that I would want to use this practically (for many reasons) but out of strict curiousity I would like to know if there is a way to reverse order a string using LINQ and/or LAMBDA expressions in one line of code, without utilising any framework "Reverse" methods. e.g. string value = "reverse me"; string reversedValue = (....); and reversedValue will result in "em esrever" EDIT Clearly an impractical problem/solution I know this, so don't worry it's strictly a curiosity question around the LINQ/LAMBDA construct.

• NuGet Update Error?

  - by Myles McDonnell

  Using the NuGet package manager dialog at the solution level in the normal course of updating a package reference once the process is complete there is a green tick on the item and the update button disappears. However, with certain of my packages the update process completes, as far as I can tell successfully, but no green tick and the update button remains. Press it again and the next dialog shows that no projects require an update for that package. Am I missing something here or is this a bug?

• Creating a list of lists with consecutive numbers

  I am looking for a convenient way to create a list of lists for which the lists within the list have consecutive numbers.

• How do I oly show some nodes (edges) on graphviz and not others

  - by Pietro Speroni

  I have a very complex graph, and there is no way that I can show it all and understand it. I need to make simplified versions of it showing only some nodes and not others. I don't just want the other nodes to be invisible, but to really be absent (so that the graph is simplified). The solution would be to make a graph with only some layers. But is that possible? What other options are there? Thanks, Pietro
