  • how to go through a string array and apply functions for different strings?

    - by Newbie
    Ok, this may be really noobish question, but i am wishing there is something i dont know yet. I go through a file, and check which string each line has, depending on the string value i execute a different function for it (or functions). This is how i do it now: if(str == "something"){ // do stuff }else if(str == "something else"){ // do stuff }else if(str == "something more"){ // do stuff }else if(str == "something again"){ // do stuff }else if(str == "something different"){ // do stuff }else if(str == "something really different"){ // do stuff } I am afraid this will become "slow" after i have to repeat those else if lines a lot... I tried to use switch() statement, but obviously it doesnt work here, is there something similar to switch() to use here?

  • Integrate Lucene or any other search product with SQL server 2005

    - by HBACHARYA
    Hi, I need to use full text search with SQL server 2005 and I have explored its inbuilt search approach (SQL server full text indexing) but it seems less powerful. I have also looked features of Lucene. Now my questions: Is is possible to integrate lucene and SQL server in anyway? 1. Can my T-Sql queries use Lucene index for returning results? (May be uses CLR based function internally) 2. How to update Lucene index while data in the tables are getting updated 3. What can be overall architecutre? 4. Are there any commercial products avaliable which provides this kind of support? Thanks, HB

  • Different RegisterWindowMessage() names appear the same

    - by Mike Trader
    Using the C/C++ Windows API RegisterWindowMessage() I am using the name of the application as the message name. Next I call CreatMutex() using the same name so that I can tell if it already exists. If it does, I know this application is already running and not to launch a second instance of it. THis is the operation of my function Running() My confusion is over the message name. It seems that "AutoConvert.exe" and "AutoAppend.exe" are interpreted as the same name. Why?

  • Whhether or not it is an elegant way in such a situation?

    - by z_axis
    There are some text files which needed to be manipulated line by line. I wrote a withFile function as below: let withFile fn handle = let rec iter_lines fh = try handle (input_line fh); iter_lines fh with _ -> close_in fh in iter_lines (open_in fn);; So i can manipulate each file as : withFile "file1.txt" (fun line -> (*...*)) withFile "file2.txt" (fun line -> (*...*)) ... But i amnot sure how to exit elehantly when i donot want to handle all lines. For example: withFile "file3.txt" (fun line -> (*when the line meets some condition, i will exit without handling other lines*) ); Any suggestion is appreciated !

  • Cartesian Plane

    - by NuNu
    I'm trying to define a function in Haskell that takes an integer argument c and returns the list of all points on the cartesian plane of the form (x/c,y/c) where x and y are integers. x/c is between -2 and 1 and y/r is between -1 and 1 This is what I've gotten so far which I'm almost sure is right but I'm getting a parse error on input = when I run it particularly at this line: cart xs ys c = [(y/c,x/c) | x <- xs, y <- ys] plane :: Int -> [a] plane c = cart [-1*c .. 1*c] [-2*c .. 1*c] c cart xs ys c = [(y/c,x/c) | x <- xs, y <- ys] A sample output would be: plane 1 would generate: [(-2.0, -1.0), (-1.0, -1.0), ( 0.0, -1.0), ( 1.0, -1.0), (-2.0, 0.0), (-1.0, 0.0), ( 0.0, 0.0), ( 1.0, 0.0), (-2.0, 1.0), (-1.0, 1.0), ( 0.0, 1.0), ( 1.0, 1.0)] Anyone have any idea how I can fix this! Thanks

  • Javascript Shift+Enter (Firefox)

    - by Stephen MCGinley
    Hi guys, Had a look and found some things on this, but nothing seems to work as I'd like it. Initially I had my solution working with internet explorer and chrome, but not firefox (which is unsatisfactory for me to not have working) What I'm looking for is a simple text area, which sends data on enter key, but creates a new line on Shift+Enter. The following is what I have function goReturn(e,str) { var e = (window.Event) ? e.which : e.keyCode; if (e.shiftKey && e=="13") { document.getElementById("wall").value = document.getElementById("wall").value+"\n"; } else if(e=="13"){ // ...continue to send data } } This sends the data on enter, but also sends the data on shift and enter (which is the problem I have). Thanks for any assistance

  • update portlet without refreshing portal page

    - by mike
    I'm trying to create a simple agena portlet. Now I've developed a basic one using spring-portlet-mvc, it allows you to navigate to the next and previous month with thusly named links that invoke a previousMonth or nextMonth function in my controller. Now the problem I'm having is that this navigation causes my whole page to refresh. Now I was wondering what the best way to fix this was. I've been looking around a bit and it looks like jquery/ajax will do the trick, but since I don't have any experience yet with that technology I was wondering if anyone had any pointers/better ideas to solve my problem.

  • Remove specified text from beginning of lines only if present (C#)

    - by Zach
    I have a textbox in which the user can edit text, in a scripting language. I've figured out how to let the user comment out lines in one click, but can't seem to figure out how to uncomment properly. For example, if the box has: Normal Text is here More normal text -- Commented text -- More commented text Normal Text again --Commented Text Again So, when the user selects any amount of text and decides to uncomment, the "--" is removed from the beginning of the lines that have it. The lines without the "--" should be unaffected. In short, I want an uncomment function that performs similar to the one in Visual Studio. Is there any way to accomplish this? Thanks

  • maching strings

    - by kiran
    Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions for def countSubStringMatch(target,key): and def countSubStringMatchRecursive (target, key): For the remaining problems, we are going to explore other substring matching ideas. These problems can be solved with either an iterative function or a recursive one. You are welcome to use either approach, though you may find iterative approaches more intuitive in these cases of matching linear structures.

  • MVC Helper Extension issue

    - by BeCool
    Hi, I need to implement a HtmlHelper extension in my MVC project simply just to output some string but ONLY in the DEBUG mode, not in REALEASE. My first attempt would be: [Conditional("DEBUG")] public static string TestStringForDebugOnly(this HtmlHelper helper, string testString) { return testString; } But obviously that would give a compile error: "The Conditional attribute is not valid because its return type is not void." So my understanding is once you set [Condition] attribute, it doesnt allow to return anything? why? What is other way to implement this kind of function? anyone help would be much appreciated. Thanks!

  • Prototype Element.remove() not working in IE

    - by Gonçalo Queirós
    Hi there. I have a javascript function that gets a DIV by an ID and makes a clone. Then, removes the original DIV from DOM and inserts the cloned object..Everything works fine, except in IE, because the original DIV is never removed... var loadingDiv = $(Sybil.conf.loadingDivId), loadingClone = loadingDiv.clone(true); console.log($$('.loadingImg')); loadingDiv.remove(); //Insert the loading div on the page again elt.insert({after: loadingClone}); [loadingClone].invoke(func); console.log($$('.loadingImg')); The div also has a span inside with the class "loadingImg", so i just used the console.log to check how many elements there are. FF always prints [span.loadingImg] but IE prints [span.loadingImg,span.loadingImg] on the second console.log... Any idea of what might be happening? Thanks

  • Why are configuration arrays acceptible parameters in PHP and Javascript?

    - by RenderIn
    In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

  • didSelectRowAtIndexPath being called after viewDidLoad of the called view

    - by Serguei Fedorov
    I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

  • Results from two queries at once in sqlite?

    - by SF.
    I'm currently trying to optimize the sluggish process of retrieving a page of log entries from the SQLite database. I noticed I almost always retrieve next entries along with count of available entries: SELECT time, level, type, text FROM Logs WHERE level IN (%s) ORDER BY time DESC, id DESC LIMIT LOG_REQ_LINES OFFSET %d* LOG_REQ_LINES ; together with total count of records that can match current query: SELECT count(*) FROM Logs WHERE level IN (%s); (for a display "page n of m") I wonder, if I could concatenate the two queries, and ask them both in one sqlite3_exec() simply concatenating the query string. How should my callback function look then? Can I distinguish between the different types of data by argc? What other optimizations would you suggest?

  • In a C++ template, is it allowed to return an object with spesific type parameters?

    - by nieldw
    When I've got a template with certain type parameters, is it allowed for a function to return an object of this same template, but with different types? In other words, is the following allowed? template<class edgeDecor, class vertexDecor, bool dir> Graph<edgeDecor,int,dir> Graph<edgeDecor,vertexDecor,dir>::Dijkstra(vertex s, bool print = false) const { /* Construct new Graph with apropriate decorators */ Graph<edgeDecor,int,dir> span = new Graph<edgeDecor,int,dir>(); /* ... */ return span; }; If this is not allowed, how can I accomplish the same kind of thing?

  • can not find out if the div element is already set in body in chrome extension

    - by alpham8
    in my chrome extension I got an div, which I will add to the body of the current tab. I am listening to chrome.tabs.onUpdated. If this event is called, I execute a script inside content_scripts. In this function there I´ll wait till the document is ready with jQuery $(document).ready(...). I try to access $("#div").length and sometimes it returns 1 and sometimes 0. It should added to the body, if it´s not already there. For some strange reasons, the onUpdated event is called twice on each page reload. Actually I found no way to check safely if the div was already added.

  • Mapping restful ajax requests to spring

  • How to handle this "session failed to write file" error in PHP?

    - by alex
    I am using the Kohana 3 framework, and am using the native session driver. For some reason, occasionally the sessions fail to write to their file. Warning: session_start() [function.session-start]: open(/tmp/sess_*****, O_RDWR) failed: Permission denied (13) in /home/site/public_html/system/classes/kohana/session/native.php on line 27 I am pretty sure Kohana has its own in built error handler, but it is not triggered with this error (i.e. it shows up like a normal PHP error, not the Kohana error). Anyone that has ever used Kohana will notice this seems to have bypassed Kohana's error handling (perhaps set with set_error_handler()). Is there anyway to stop this error from appearing without switching from the native session (i.e. file based) driver? Should I just give good practice the boot and append an @ error suppressor to session_start() in the core code of Kohana? Should I relax the error_reporting()? Thanks

  • how to find which libraries to link to? or, how can I create *-config (such as sdl-config, llvm-con

    - by numeric
    Hey, I want to write a program that outputs a list of libraries that I should link to given source code (or object) files (for C or C++ programs). In *nix, there are useful tools such as sdl-config and llvm-config. But, I want my program to work on Windows, too. Usage: get-library-names -l /path/to/lib a.cpp b.cpp c.cpp d.obj Then, get-library-names would get a list of function names that are invoked from a.cpp, b.cpp, c.cpp, and d.obj. And, it'll search all library files in /path/to/lib directory and list libraries that are needed to link properly. Is there such tool already written? Is it not trivial to write a such tool? How do you find what libraries you should link to? Thanks.

  • ASP/HTML problem with spaces and monofonts

    - by nickik
    I have a ASP has a Function that converts ä to &auml so far so good. I have lets say space for 10 char's if there are more cut them of if there are less fill the space up with &nbsp's. . Like this: test &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp but if i say "täst" it does this: te &auml t &nbsp It interprets the &auml not as one char it looks at it as 6 chars. Is there a clever way around that? This problem messes up my design because I need the right count of spaces. The whole thing goes into a big select box. Of you have to add a ; at the end of ever &... I could add them because the Editor would really interprt them.

  • nested list comprehension using intermediate result

    - by KentH
    I am trying to grok the output of a function which doesn't have the courtesy of setting a result code. I can tell it failed by the "error:" string which is mixed into the stderr stream, often in the middle of a different conversion status message. I have the following list comprehension which works, but scans for the "error:" string twice. Since it is only rescanning the actual error lines, it works fine, but it annoys me I can't figure out how to use a single scan. Here's the working code: errors = [e[e.find('error:'):] for e in err.splitlines() if 'error:' in e] The obvious (and wrong) way to simplify is to save the "find" result errors = [e[i:] for i in e.find('error:') if i != -1 for e in err.splitlines()] However, I get "UnboundLocalError: local variable 'e' referenced before assignment". Blindly reversing the 'for's in the comprehension also fails. How is this done? THanks. Kent

  • Wait for animation, render to complete - XAML and C#

    - by Adam S
    Hi all. I have a situation where I am animating part of my XAML application, and I need to wait for the animation AND rendering to complete before I can move on in my code. So far the tail end of my function looks like: ProcExpandCollapse.Begin(); while (ProcExpandCollapse.GetCurrentState() != ClockState.Stopped) { } } Which, in theory, will wait until the animation is finished. But it will not wait until the rendering is finished - the thread drawing the application might still not have re-drawn the animation. The animation is expanding a UIElement, and then the next part of my code uses it's rendered size to do some things. My question then is, how do I wait until my UI Element is re-rendered before moving on?
