  • PHP/MySQL Printing Duplicate Labels

    - by Michael
    Using an addon of FPDF, I am printing labels using PHP/MySQL (http://www.fpdf.de/downloads/addons/29/). I'd like to be able to have the user select how many labels to print. For example, if the query puts out 10 records and the user wants to print 3 labels for each record, it prints them all in one set. 1,1,1,2,2,2,3,3,3...etc. Any ideas? <?php require_once('auth.php'); require_once('../config.php'); require_once('../connect.php'); require('pdf/PDF_Label.php'); $sql="SELECT $tbl_members.lastname, $tbl_members.firstname, $tbl_members.username, $tbl_items.username, $tbl_items.itemname FROM $tbl_members, $tbl_items WHERE $tbl_members.username = $tbl_items.username"; $result=mysql_query($sql); if(mysql_num_rows($result) == 0){ echo "Your search criteria does not return any results, please try again."; exit(); } $pdf = new PDF_Label("5160"); $pdf->AddPage(); // Print labels while($rows=mysql_fetch_array($result)){ $name = $rows['lastname'].', '.$rows['firstname'; $item= $rows['itemname']; $text = sprintf(" * %s *\n %s\n", $name, $item); $pdf->Add_Label($text); } $pdf->Output('labels.pdf', 'D'); ?>

  • Visual Studio expression containing a term named "by" cannot be evaluated in the watch window

    - by Andrei Pana
    Consider my C++ code below: int _tmain(int argc, _TCHAR* argv[]) { int by = 10; printf("%d\n", by); int bx = 20; printf("%d\n", (by + bx)); return 0; } which works fine. The funny thing is with the "by" variable. If I try to add a watch for a simple expression that contains by, the result will be CXX0030: Error: expression cannot be evaluated. For example, on a breakpoint on return 0, if I add the following watches I get the results mentioned: by : 10 bx : 20 by + 5 : CXX0030: Error: expression cannot be evaluated bx + 5 : 25 by + bx : CXX0030: Error: expression cannot be evaluated (by) + bx : 30 by + (bx) : CXX0030: Error: expression cannot be evaluated bx + (by) : CXX0014: Error: missing operrand This happens on VS2010, VS2008 on multiple computers. So, more out of curiosity, what is happening with "by"? Is it some kind of strange operator? Why doesn't bx get the same treatment? (I've tried google on this but it is quite difficult to get some relevant hits with terms like "by")

  • SOLR phrase query

    - by Alex
    I have a slight problem when searching with SOLR 4.0 and attempting a phrase query. I have a field called "idx_text_general_ci" which is a case insensitive (all lowercased) field made up of all fields. When I try and search for a phrase (marine fitter) my SOLR refuses to search for the phrase instead splitting the phrase into 2 words - /select?defType=edismax&q=idx_text_general_ci:marine%20fitter&debugQuery=true debugQuery=true output below: <lst name="debug"> <str name="rawquerystring">idx_text_general_ci:marine fitter</str> <str name="querystring">idx_text_general_ci:marine fitter</str> <str name="parsedquery"> (+(idx_text_general_ci:marine DisjunctionMaxQuery((id:fitter))))/no_coord </str> <str name="parsedquery_toString">+(idx_text_general_ci:marine (id:fitter))</str> As you can see above it splits the query into 2 parts (idx_text_general_ci:marine then id:fitter). THe problem I have is that I have an exact match for "marine fitter" that appears twice in the idx_text_general_ci field yet it's ranked with a lesser score than a document with the word "marine" appearing 3 times. I know this will not be the case if my SOLR was to search the field with the phrase as expected. If I wrap the phrase in quotes I get zero results. Any help or a nudge in the right direction would be much appreciated. Thanks in advance Alex

  • Form is submitting when the page loads

    - by RailAddict
    I have a really simple Rails app. Basically an article with comments. I want the article page to show the article, comments underneath and then a textbox to write a comment and a submit button to submit it. I got it all working except for one (big) problem. When the page loads.. example.com/article/1 a blank comment is submitted to the database. I fixed that by including "validates_presence_of :body" in the Comment model. But that results in the following image when the page loads: This is my code by the way: def show @place = Article.find(params[:id]) @comment = Article.find(params[:id]).comments.create(params[:comment]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @article } end end and <% form_for([@article, @comment]) do |f| %> <p> <%= f.label :commenter %><br /> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %><br /> <%= f.text_area :body %> </p> <p> <%= f.submit "Create" %> </p> <% end %>

  • How can I coordinate code review tool and RCS (specifically git)

    - by Chris Nelson
    We're committed to git for code management. We're trying to find a tool that will help us systematize code reviews. We're considering Gerrit and Code Collaborator but would welcome other suggestions. We're having a problem answering the question, "How do we know every commit was reviewed?" (Or "What commits have yet to be reviewed?") One answer would be to submit every commit or every push for review and track incomplete reviews in the review tool. I'm not entirely happy with relying on a another tool -- especially if it's not open source -- to tell us this. What seems to be a better answer is to rely on sign offs in git (e.g., "Signed-off-by: Chris Nelson") and use a hook in the review tool to sign off commits on behalf of the reviewer. And advantage of this is if we use some other review mechanism for some commits, we have just one place to look for results. One problem with this is that we can't require review before push because the review tool is unlikely to have access to the developer's private repository clone to add the sign-off. Any ideas on integrating code review with code management to achieve ease of use and high visibility of unreviewed changes?

  • JVM segmentation faults due to "Invalid memory access of location"

    - by Dan
    I have a small project written in Scala 2.9.2 with unit tests written using ScalaTest. I use SBT for compiling and running my tests. Running sbt test on my project makes the JVM segfault regularly, but just compiling and running my project from SBT works fine. Here is the exact error message: Invalid memory access of location 0x8 rip=0x10959f3c9 [1] 11925 segmentation fault sbt I cannot locate a core dump anywhere, but would be happy to provide it if it can be obtained. Running java -version results in this: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) But I've also got Java 7 installed (though I was never able to actually run a Java program with it, afaik). Another issue that may be related: some of my test cases contain titles including parentheses like ( and ). SBT or ScalaTest (not sure) will consequently insert square parens in the middle of the output. For example, a test case with the name (..)..(..) might suddenly look like (..[)..](..). Any help resolving these issues is much appreciated :-) EDIT: I installed the Java 7 JDK, so now java -version shows the right thing: java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) This also means that I now get a more detailed segfault error and a core dump: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x000000010a71a3e3, pid=16830, tid=19459 # # JRE version: 7.0_07-b10 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.3-b01 mixed mode bsd-amd64 compressed oops) # Problematic frame: # V [libjvm.dylib+0x3cd3e3] And the dump.

  • how to get cartesian products between database and local sequences in linq?

    - by JD
    I saw this similar question here but can't figure out how to use Contains in Cartesian product desired result situation: http://stackoverflow.com/questions/1712105/linq-to-sql-exception-local-sequence-cannot-be-used-in-linq-to-sql-implementatio Let's say I have following: var a = new [] { 1, 4, 7 }; var b = new [] { 2, 5, 8 }; var test = from i in a from j in b select new { A = i, B = j, AB = string.Format("{0:00}a{1:00}b", i, j), }; foreach (var t in test) Console.Write("{0}, ", t.AB); This works great and I get a dump like so (note, I want the cartesian product): 01a02b, 01a05b, 01a08b, 04a02b, 04a05b, 04a08b, 07a02b, 07a05b, 07a08b, Now what I really want is to take this and cartesian product it again against an ID from a database table I have. But, as soon as I add in one more from clause that instead of referencing objects, references SQL table, I get an error. So, altering above to something like so where db is defined as a new DataContext (i.e., class deriving from System.Data.Linq.DataContext): var a = new [] { 1, 4, 7 }; var b = new [] { 2, 5, 8 }; var test = from symbol in db.Symbols from i in a from j in b select new { A = i, B = j, AB = string.Format("{0}{1:00}a{2:00}b", symbol.ID, i, j), }; foreach (var t in test) Console.Write("{0}, ", t.AB); The error I get is following: Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operator Its related to not using Contains apparently but I'm unsure how Contains would be used when I don't really want to constrict the results - I want the Cartesian product for my situation. Any ideas of how to use Contains above and still yield the Cartesian product when joining database and local sequences?

  • P6 Architecture - Register renaming aside, does the limited user registers result in more ops spent

    - by mrjoltcola
    I'm studying JIT design with regard to dynamic languages VM implementation. I haven't done much Assembly since the 8086/8088 days, just a little here or there, so be nice if I'm out of sorts. As I understand it, the x86 (IA-32) architecture still has the same basic limited register set today that it always did, but the internal register count has grown tremendously, but these internal registers are not generally available and are used with register renaming to achieve parallel pipelining of code that otherwise could not be parallelizable. I understand this optimization pretty well, but my feeling is, while these optimizations help in overall throughput and for parallel algorithms, the limited register set we are still stuck with results in more register spilling overhead such that if x86 had double, or quadruple the registers available to us, there may be significantly less push/pop opcodes in a typical instruction stream? Or are there other processor optmizations that also optimize this away that I am unaware of? Basically if I've a unit of code that has 4 registers to work with for integer work, but my unit has a dozen variables, I've got potentially a push/pop for every 2 or so instructions. Any references to studies, or better yet, personal experiences?

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Making dtSearch highlight one hit per phrase, rather than one hit per word-in-a-phrase

    - by Chris
    I'm using dtSearch to highlight text search matches within a document. The code to do this, minus some details and cleanup, is roughly along these lines: SearchJob sj = new SearchJob(); sj.Request = "\"audit trail\""; // the user query sj.FoldersToSearch.Add(path_to_src_document); sj.Execute(); FileConverter fileConverter = new FileConverter(); fileConverter.SetInputItem(sj.Results, 0); fileConvert.BeforeHit = "<a name=\"HH_%%ThisHit%%\"/><b>"; fileConverter.AfterHit = "</b>"; fileConverter.Execute(); string myHighlightedDoc = fileConverter.OutputString; If I give dtSearch a quoted phrase query like "audit trail" then dtSearch will do hit highlighting like this: An <a name="HH_0"/><b>audit</b> <a name="HH_1"/><b>trail</b> is a fun thing to have an <a name="HH_2"/><b>audit</b> <a name="HH_last"/><b>trail</b> about! Note that each word of the phrase is highlighted separately. Instead, I would like phrases to get highlighted as whole units, like this: An <a name="HH_0"/><b>audit trail</b> is a fun thing to have an <a name="HH_last"/><b>audit trail</b> about! This would A) make highlighting look better, B) improve behavior of my javascript that helps users navigate from hit to hit, and C) give more accurate counts of total # hits. Is there good ways to make dtSearch highlight phrases this way?

  • How do I connect to a Java command-line tool with the YourKit Java Profiler?

    - by Daryl Spitzer
    I've build a command-line tool in Java, which I would now like to profile with YourKit. I launch the command-line tool with something like: $ java -classpath .:foo.bar.jar com.foobar.tools.TheTool arg1 arg2 arg3 It runs to completion in less than 2 seconds. After reading http://www.yourkit.com/docs/80/help/agent.jsp, I tried the following: $ java -agentpath:/home/dspitzer/yjp-8.0.24/bin/linux-x86-32/libyjpagent.so -classpath .:foo.bar.jar com.foobar.tools.TheTool arg1 arg2 arg3 ...and I get: [YourKit Java Profiler 8.0.24] JVMTI version 3001016d; 14.3-b01; Sun Microsystems Inc.; mixed mode, sharing; Linux; 32-bit JVM [YourKit Java Profiler 8.0.24] Profiler agent is listening on port 10001... [YourKit Java Profiler 8.0.24] *** HINT ***: To get profiling results, connect to the application from the profiler UI ... But I guess YourKit is designed to only connect to running application. How should I modify my command-line tool to allow connection from YourKit? I could add a command-line option that will have it pause for input, and I won't press return for it to continue until I've connected to it from YourKit. Is there a YourKit API that I could add to my tool that would cause it to block until I've connected with YourKit? Is there a YourKit API or a java command-line option that would create a profiling "snapshot" that I could load and analyze later (after the command-line tool has completed) with YourKit?

  • matlab precision determint problem

    I have the following program format compact; format short g; clear; clc; L = 140; J = 77; Jm = 10540; G = 0.8*10^8; d = L/3; for i=1:500000 omegan=1.+0.0001*i; a(1,1) = ((omegan^2)*(Jm/(G*J))*d^2)-2; a(1,2) = 2; a(1,3) = 0; a(1,4) = 0; a(2,1) = 1; a(2,2) = ((omegan^2)*(Jm/(G*J))*d^2)-2; a(2,3) = 1; a(2,4) = 0; a(3,1) = 0; a(3,2) = 1; a(3,3) = ((omegan^2)*(Jm/(G*J))*d^2)-2; a(3,4) = 1; a(4,1) = 0; a(4,2) = 0; a(4,3) = 2; a(4,4) = ((omegan^2)*(Jm/(G*J))*d^2)-2; if(abs(det(a))<1E-10) sprintf('omegan= %8.3f det= %8.3f',omegan,det(a)) end end Analytical solution of the above system, and the same program written in fortran gives out values of omegan equal to 16.3818 and 32.7636 (fortran values; analytical differ a little, but they're there somewhere). So, now I'm wondering ... where am I going wrong with this ? Why is matlab not giving the expected results ? (this is probably something terribly simple, but it's giving me headaches)

  • Catching MediaPlayer Exceptions from WPF MediaElement Control

    - by ScottCate
    I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

  • How do I pass an array of structs (containing std:string or BSTR) from ATL to C#. SafeArray? Varian

    - by Andrew
    Hi, I have an ATL COM object that I am using from C#. The interface currently looks like: interface ICHASCom : IDispatch{ [id(1), helpstring("method Start")] HRESULT Start([in] BSTR name, [out,retval] VARIANT_BOOL* result); ... [id(4), helpstring("method GetCount")] HRESULT GetCount([out,retval] LONG* numPorts); ... [id(7), helpstring("method EnableLogging")] HRESULT EnableLogging([in] VARIANT_BOOL enableLogging); }; That is, it's a very simple interface. I also have some events that I send back too. Now, I would like to add something to the interface. In the ATL I have some results, which are currently structs and look like struct REPORT_LINE { string creationDate; string Id; string summary; }; All the members of the struct are std::string. I have an array of these that I need to get back to the C#. What's the best way to do this? I suspect someone is going to say, "hey, you can't just send std::string over COM like that. If so, fine, but what's the best way to modidfy the struct? Change the std::string to BSTR? And then how do I, 1) Set up the IDL to pass an array of structs (structs with BSTR or std::string) 2) If I must use SAFEARRAYS, how do I fill the SAFEARRAYS with the structs. I'm not familiar with COM except for use with simple types. Thanks, Dave

  • CURL & web.py: transfer closed with outstanding read data remaining

    - by Richard J
    Hi Folks, I have written a web.py POST handler, thus: import web urls = ('/my', 'Test') class Test: def POST(self): return "Here is your content" app = web.application(urls, globals()) if __name__ == "__main__": app.run() When I interact with it using Curl from the command line I get different responses depending on whether I post it any data or not: curl -i -X POST http://localhost:8080/my HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:42:41 GMT Server: CherryPy/3.1.2 WSGI Server Here is your content (Posting of no data to the server gives me back the "Here is your content" string) curl -i -X POST --data-binary "@example.zip" http://localhost:8080/my HTTP/1.1 100 Content-Length: 0 Content-Type: text/plain HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:43:47 GMT Server: CherryPy/3.1.2 WSGI Server curl: (18) transfer closed with outstanding read data remaining (Posting example.zip to the server results in this error) I've scoured the web.py documentation (what there is of it), and can't find any hints as to what might be going on here. Possibly something to do with 100 continue? I tried writing a python client which might help clarify: h1 = httplib.HTTPConnection('localhost:8080') h1.request("POST", "http://localhost:8080/my", body, headers) print h1.getresponse() body = the contents of the example.zip, and headers = empty dictionary. This request eventually timed out without printing anything, which I think exonerates curl from being the issue, so I believe something is going on in web.py which isn't quite right (or at least not sufficiently clear) Any web.py experts got some tips? Cheers, Richard

  • ADO.NET Batch Insert with over 2000 parameters

    - by Liming
    Hello all, I'm using Enterprise library, but the idea is the same. I have a SqlStringCommand and the sql is constructed using StringBuilder in the forms of "insert into table (column1, column2, column3) values (@param1-X, @param2-X, @parm3-X)"+" " where "X" represents a "for loop" about 700 rows StringBuilder sb = new StringBuilder(); for(int i=0; i<700; i++) { sb.Append("insert into table (column1, column2, column3) values (@param1-"+i+", @param2-"+i, +",@parm3-"+i+") " ); } followed by constructing a command object injecting all the parameters w/ values into it.

  • ASP.net AppendHeader not working in ASP MVC

    - by Chao
    I'm having problems getting AppendHeader to work properly if I am also using an authorize filter. I'm using an actionfilter for my AJAX actions that applies Expires, Last-Modified, Cache-Control and Pragma (though while testing I have tried including it in the action method itself with no change in results). If I don't have an authorize filter the headers work fine. Once I add the filter the headers I tried to add get stripped. The headers I want to add Response.AppendHeader("Expires", "Sun, 19 Nov 1978 05:00:00 GMT"); Response.AppendHeader("Last-Modified", String.Format("{0:r}", DateTime.Now)); Response.AppendHeader("Cache-Control", "no-store, no-cache, must-revalidate"); Response.AppendHeader("Cache-Control", "post-check=0, pre-check=0"); Response.AppendHeader("Pragma", "no-cache"); An example of the headers from a correct page: Server ASP.NET Development Server/9.0.0.0 Date Mon, 14 Jun 2010 17:22:24 GMT X-AspNet-Version 2.0.50727 X-AspNetMvc-Version 2.0 Pragma no-cache Expires Sun, 19 Nov 1978 05:00:00 GMT Last-Modified Mon, 14 Jun 2010 18:22:24 GMT Cache-Control no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Content-Type text/html; charset=utf-8 Content-Length 352 Connection Close And from an incorrect page: Server ASP.NET Development Server/9.0.0.0 Date Mon, 14 Jun 2010 17:27:34 GMT X-AspNet-Version 2.0.50727 X-AspNetMvc-Version 2.0 Pragma no-cache, no-cache Cache-Control private, s-maxage=0 Content-Type text/html; charset=utf-8 Content-Length 4937 Connection Close

  • How to scrape Google SERP based on copyright year?

    - by Michael Mao
    Hi all: I know there must be ways to do this sort of things. I am not pro in RoR or Python, not even an expert in PHP. So my solution tends to be quite dumb: It uses a FireFox add-on called imarcos to scrape the target urls from Google SERP, and use PHP to store info into the database. At the very core of my workaround there lies a problem: How to specifically find target urls based on their copyright year? I mean, something like "copyright 1998-2006" in the footer is to be considered a target, but my search results are not 100% accurate. I used the following url to search : http://www.google.com.au/#hl=en&q=inurl:.com.au+intext:copyright+1995..2007+--2008+--2009&start=0&cad=b&fp=6a8119b094529f00 It reads : search for pages that have .com.au in URL and a copyright range from 1995 to 2007 exclude the year of 2008 or 2009. Starting position is 0, of course the offset can be changed. I've already done a dummy list and honestly I am not pleased with the result. That's mostly because I cannot find a way to restrict search terms in the exact order as they are entered into the search url. copyright can appear in anywhere on page and doesn't necessarily before the years, that's the current story. Is there a more clear way to sort out this? Oh, almost forgot to say the client doesn't wanna spent too much in this - I cannot persuade him simply buy some cool software, unfortunately. I hope there is a way to use clever Google search operators or similar things to go around this issue. Many thanks in advance!

  • Force creation of query execution plan

    - by Marc
    I have the following situation: .net 3.5 WinForm client app accessing SQL Server 2008 Some queries returning relatively big amount of data are used quite often by a form Users are using local SQL Express and restarting their machines at least daily Other users are working remotely over slow network connections The problem is that after a restart, the first time users open this form the queries are extremely slow and take more or less 15s on a fast machine to execute. Afterwards the same queries take only 3s. Of course this comes from the fact that no data is cached and must be loaded from disk first. My question: Would it be possible to force the loading of the required data in advance into SQL Server cache? Note My first idea was to execute the queries in a background worker when the application starts, so that when the user starts the form the queries will already be cached and execute fast directly. I however don't want to load the result of the queries over to the client as some users are working remotely or have otherwise slow networks. So I thought just executing the queries from a stored procedure and putting the results into temporary tables so that nothing would be returned. Turned out that some of the result sets are using dynamic columns so I couldn't create the corresponding temp tables and thus this isn't a solution. Do you happen to have any other idea?

  • Calculating odds distribution with 6-sided dice

    - by Stephen
    I'm trying to calculate the odds distribution of a changing number of 6-sided die rolls. For example, 3d6 ranges from 3 to 18 as follows: 3:1, 4:3, 5:6, 6:10, 7:15, 8:21, 9:25, 10:27, 11:27, 12:25, 13:21, 14:15, 15:10, 16:6, 17:3, 18:1 I wrote this php program to calculate it: function distributionCalc($numberDice,$sides=6) { for ( $i=0; $i<pow($sides,$numberDice); $i++) { $sum=0; for ($j=0; $j<$numberDice; $j++) { $sum+=(1+(floor($i/pow($sides,$j))) % $sides); } $distribution[$sum]++; } return $distribution; } The inner $j for-loop uses the magic of the floor and modulus functions to create a base-6 counting sequence with the number of digits being the number of dice, so 3d6 would count as: 111,112,113,114,115,116,121,122,123,124,125,126,131,etc. The function takes the sum of each, so it would read as: 3,4,5,6,7,8,4,5,6,7,8,9,5,etc. It plows through all 3^6 possible results and adds 1 to the corresponding slot in the $distribution array between 3 and 18. Pretty straightforward. However, it only works until about 8d6, afterward i get server time-outs because it's now doing billions of calculations. But I don't think it's necessary because die probability follows a sweet bell-curve distribution. I'm wondering if there's a way to skip the number crunching and go straight to the curve itself. Is there a way to do this, so, for example, with 80d6 (80-480)? Can the distribution be projected without doing 6^80 calculations? I'm not a professional coder and probability is still new to me, so thanks for all the help! Stephen

  • How to connect a new query script with SSMS add-in?

    - by squillman
    I'm trying to create a SSMS add-in. One of the things I want to do is to create a new query window and programatically connect it to a server instance (in the context of a SQL Login). I can create the new query script window just fine but I can't find how to connect it without first manually connecting to something else (like the Object Explorer). So in other words, if I connect Obect Explorer to a SQL instance manually and then execute the method of my add-in that creates the query window I can connect it using this code: ServiceCache.ScriptFactory.CreateNewBlankScript( Editors.ScriptType.Sql, ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo, null); But I don't want to rely on CurrentlyActiveWndConnectionInfo.UIConnectionInfo for the connection. I want to set a SQL Login username and password programatically. Does anyone have any ideas? EDIT: I've managed to get the query window connected by setting the last parameter to an instance of System.Data.SqlClient.SqlConnection. However, the connection uses the context of the last login that was connected instead of what I'm trying to set programatically. That is, the user it connects as is the one selected in the Connection Dialog that you get when you click the New Query button and don't have an Object Explorer connected. EDIT2: I'm writing (or hoping to write) an add-in to automatically send a SQL statement and the execution results to our case-tracking system when run against our production servers. One thought I had was to remove write permissions and assign logins through this add-in which will also force the user to enter a case # canceling the statement if it's not there. Another thought I've just had is to inspect the server name in ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo and compare it to our list of production servers. If it matches and there's no case # then cancel the query.

  • delayed evaluation of code in subroutines - 5.8 vs. 5.10 and 5.12

    - by Brock
    This bit of code behaves differently under perl 5.8 than it does under perl 5.12: my $badcode = sub { 1 / 0 }; print "Made it past the bad code.\n"; [brock@chase tmp]$ /usr/bin/perl -v This is perl, v5.8.8 built for i486-linux-gnu-thread-multi [brock@chase tmp]$ /usr/bin/perl badcode.pl Illegal division by zero at badcode.pl line 1. [brock@chase tmp]$ /usr/local/bin/perl -v This is perl 5, version 12, subversion 0 (v5.12.0) built for i686-linux [brock@chase tmp]$ /usr/local/bin/perl badcode.pl Made it past the bad code. Under perl 5.10.1, it behaves as it does under 5.12: brock@laptop:/var/tmp$ perl -v This is perl, v5.10.1 (*) built for i486-linux-gnu-thread-multi brock@laptop:/var/tmp$ perl badcode.pl Made it past the bad code. I get the same results with a named subroutine, e.g. sub badcode { 1 / 0 } I don't see anything about this in the perl5100delta pod. Is this an undocumented change? A unintended side effect of some other change? (For the record, I think 5.10 and 5.12 are doing the Right Thing.)
