• In Java, how do you parse through a single word string?

  - by Fraz

  I'm trying to parse though a string made up of a single word. How would you go about assigning the last letter of the word to a variable? I was thinking of using the Scanner class to parse the word and make each letter an element in an array but it seems Scanner.next() only goes through whole words and not the individual letters. Any help?

• How do I upload a file, process it and return a result file in a single request to a REST WCF service?

  - by sharptooth

  I need to implement the following scenario in a REST service implemented in WCF: the user submits a binary file and a set of parameters the server consumes the file, does some clever work and generates a binary output file the user retrieves that binary result file and all that is done in a single operation from the client perspective. It's pretty easy in a non-REST service. How do I do that in a REST service? Where do I get started?

• How can I "merge" or "flatten" results from a query which returns multiple rows into a single result

  - by dsm

  I have a simple query over a table, which returns results like the following: id id_type id_ref 2702 5 31 2702 16 14 2702 17 3 2702 40 1 2702 26 4 And I would like to merge the results into a single row, for instance: id concatenation 2702 5,16,17,40,26:31,14,3,1,4 Is there any way to do this within a trigger? NB: I know I can use a cursor, but I would really prefer not to unless there is no better way.

• What is the correct way to create a single instance application?

  - by Nidonocu

  Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

  I'd like to censor some words in a string by replacing each character in the word with a "*". Basically I would want to do String s = "lorem ipsum dolor sit"; s = s.replaceAll("ipsum|sit", $0.length() number of *)); so that the resulting s equals "lorem ***** dolor ***". I know how to do this with repeated replaceAll invokations, but I'm wondering, is this possible to do with a single replaceAll?
