• LINQ/C#: Where & Foreach using index in a list/array

  - by Andrew White

  Hi, I have a list/array and need to process certain elements, but also need the index of the element in the processing. Example: List Names = john, mary, john, bob, simon Names.Where(s = s != "mary").Foreach(MyObject.setInfo(s.index, "blah") But cannot use the "index" property with lists, inversely if the names were in an Array I cannot use Foreach... Any suggestions?

• How to remove list of words from strings

  - by zeljko

  What I would like to do (in Clojure): For example, I have a vector of words that need to be removed: (def forbidden-words [":)" "the" "." "," " " ...many more...]) ... and a vector of strings: (def strings ["the movie list" "this.is.a.string" "haha :)" ...many more...]) So, each forbidden word should be removed from each string, and the result, in this case, would be: ["movie list" "thisisastring" "haha"]. How to do this ?

• Linqify this: Aggregate a subset of a list

  - by JMarsch

  Suppose I have a list or array of items, and I want to sum a subset of the items in the list. (in my case, it happens to always be a sequential subset). Here's the old-fashioned way: int sum = 0; for(int i = startIndex; i <= stopIndex; i++) sum += myList[i].TheValue; return sum; What's the best way to linqify that code?

• How get list of local network computers?

  - by KindDragon

  Hello. I am trying to get a list of local network computers. I tried to use NetServerEnum and WNetOpenEnum API, but both API return error code 6118 (ERROR_NO_BROWSER_SERVERS_FOUND).

• Disabling JComboBox and retaining original item list

  - by n002213f

  My action listener on a JComboBox invokes a thread. I would like the component to be disabled until the thread completes. I have tried calling seEnabled(false) when the thread start and setEnabled(true) when it completes. Unfortunately setEnabled(false) clears the combo box list as well. Is there a way of disabling the component but retain the original list?

• comprehensive list of unsafe functions in C

  - by Dervin Thunk

  Hello. I've been looking online unsuccessfully for a comprehensive list of unsafe (dangerous) functions in C (see here for a few). When I say "dangerous" I mean functions like gets or strcopy, but I was wondering if someone has actually compiled a comprehensive list. Thank you. PD: Neil Butterworth, you should abstain from answering my posts. You're seldom helpful.

• maintaing a sorted list that is bigger than memory

  - by tcurdt

  I have a list of tuples. [ "Bob": 3, "Alice: 2, "Jane": 1, ] When incrementing the counts "Alice" += 2 the order should be maintained: [ "Alice: 4, "Bob": 3, "Jane": 1, ] When all is in memory there rather simple ways (some more or some less) to efficiently implement this. (using an index, insert-sort etc) The question though is: What's the most promising approach when the list does not fit into memory. Bonus question: What if not even the index fits into memory? How would you approach this?

• How to do a search from a list with non-prefix keywords

  - by aNui

  First of all, sorry if my english or my post got any mistakes. I am programming a program to search the name from the list and I need to find them if the keyword is not in front of the names (that's what I mean non-prefix) e.g. if I my list is the music instruments and I type "guit" to the search textbox. It should find the names "Guitar, Guitarrón, Acoustic Guitar, Bass Guitar, ..." or something like this Longdo Dictionary's search suggestion. here is my simple and stupid algorithm (that's all I can do) const int SEARCHROWLIMIT = 30; private string[] DoSearch(string Input, string[] ListToSearch) { List<string> FoundNames = new List<string>(); int max = 0; bool over = false; for (int k = 0; !over; k++) { foreach (string item in ListToSearch) { max = (max > item.Length) ? max : item.Length; if (k > item.Length) continue; if (k >= max) { over = true; break; } if (!Input.Equals("Search") && item.Substring(k, item.Length - k).StartsWith(Input, StringComparison.OrdinalIgnoreCase)) { bool exist = false; int i = 0; while (!exist && i < FoundNames.Count) { if (item.Equals(FoundNames[i])) { exist = true; break; } i++; } if (!exist && FoundNames.Count < SEARCHROWLIMIT) FoundNames.Add(item); else if (FoundNames.Count >= SEARCHROWLIMIT) over = true; } } } return FoundNames.ToArray(); } I think this algorithm is too slow for a large number of names and after several trial-and-error, I decided to add SEARCHROWLIMIT to breaks the operation And I also think there're some readymade methods that can do that. And another problem is I need to search music instruments by a category like strings, percussions, ... and by the country of origins. So I need to search them with filter by type and country. please help me. P.S. Me and my friends are just student from Thailand and developing the project to compete in Microsoft Imagine Cup 2010 and please become fan on our facebook page [KRATIB][3].

• What data formats does PowerShell most easily read ?

  - by Jim

  I'm trying to use PowerShell with SharePoint. I'd like my PowerShell scripts to load my SharePoint farm configuration from files rather than either hard coding the configuration in the scripts, or having to pass in the same parameters each time. This the kind of information I need to store. WebFrontEnds: Web1, Web2, Web3 CentralAdmin: Central1 Index: Web1 ContentWebApps: http://user1, http://user2 Does PowerShell easily load this data from CSV, XML, or other formats?
