  • Java split is eating my characters.

    - by Fenris_uy
    Hi, I have a string like this String str = "la$le\$li$lo". I want to split it to get the following output "la","le\$li","lo". The \$ is a $ escaped so it should be left in the output. But when I do str.split("[^\\\\]\\$") y get "l","le\$l","lo". From what I get my regex is matching a$ and i$ and removing then. Any idea of how to get my characters back? Thanks

  • Allow (and correct the URL) when there is a special character such as %26 using IIS and the rewrite module

    - by plumtreematt
    I'm struggling with a legacy app that uses special characters like %26 in the URL. The characters don't affect the app but can't be changed, so I'm trying to get IIS to deal with them. I've tried to ignore them using multiple methods, but nothing seems to work. So now I installed the IIS rewrite module and added a rewrite rule to web.config to replace the characters %26 with _, for example: <rewrite> <rules> <rule name="ampersand" patternSyntax="Wildcard" stopProcessing="true"> <match url="*%26*" /> <action type="Redirect" url="{R:1}_{R:2}" /> </rule> </rules> </rewrite> The problem is that IIS responds with "Bad Request" before the rewrite rule ever gets called. So my question is this: how can I change the order of precedence so that the mod rewrite filter will be called before IIS puts the ban hammer down on that URL?

  • Django ORM: Ordering w/ aggregate functions — None special treatment

    - by deno
    Hi, I'm doing query like that: SomeObject.objects.annotate(something=Avg('something')).order_by(something).all() Now, I normally have an aggregate field in my model that I use with Django signals to keep in sync, however in this case perfomance isn't an issue so I thought I'd keep it simple and just use subqueries. This approach, however, presented an unexpected issue: It all works grate if aggregate function results are like this: [5.0, 4.0, 6.0 … (etc, just numbers)] However if you mix in some Nones than it's being ordered like this: [None, 5.0, 4.0 …] The issue is that None has higher value than any number, while it should have value at most of 0. I'm using PostgreSQL and haven't tested w/ other DBs. I haven't actually checked what query is generated etc. I worked it around by just sorting in memory: sorted(…, key=lambda _:_.avg_rating if _.avg_rating is not None else 0) So I'm just curious if you know a way to do it w/ just Django ORM. Perhaps .where? or something… Kind regards

  • Encoding Special Characters For Outlook HTML Email

    - by n0chi
    I have an asp.net / C# page which takes a comment, and then emails that comment. Sometimes when the user enters "&" in the comment, the comment is being truncated. So for example if the comment is "test & test" the email only sends out "test ". I have tried HttpUtility.HtmlEncode - but it looks like the issue is on the outlook side and not on the C# side.

  • Get special numbers from a random number generator

    - by Wikeno
    I have a random number generator: int32_t ksp_random_table[GENERATOR_DEG] = { -1726662223, 379960547, 1735697613, 1040273694, 1313901226, 1627687941, -179304937, -2073333483, 1780058412, -1989503057, -615974602, 344556628, 939512070, -1249116260, 1507946756, -812545463, 154635395, 1388815473, -1926676823, 525320961, -1009028674, 968117788, -123449607, 1284210865, 435012392, -2017506339, -911064859, -370259173, 1132637927, 1398500161, -205601318, }; int front_pointer=3, rear_pointer=0; int32_t ksp_rand() { int32_t result; ksp_random_table[ front_pointer ] += ksp_random_table[ rear_pointer ]; result = ( ksp_random_table[ front_pointer ] >> 1 ) & 0x7fffffff; front_pointer++, rear_pointer++; if (front_pointer >= GENERATOR_DEG) front_pointer = 0; if (rear_pointer >= GENERATOR_DEG) rear_pointer = 0; return result; } void ksp_srand(unsigned int seed) { int32_t i, dst=0, kc=GENERATOR_DEG, word, hi, lo; word = ksp_random_table[0] = (seed==0) ? 1 : seed; for (i = 1; i < kc; ++i) { hi = word / 127773, lo = word % 127773; word = 16807 * lo - 2836 * hi; if (word < 0) word += 2147483647; ksp_random_table[++dst] = word; } front_pointer=3, rear_pointer=0; kc *= 10; while (--kc >= 0) ksp_rand(); } I'd like know what type of pseudo random number generation algorithm this is. My guess is a multiple linear congruential generator. And is there a way of seeding this algorithm so that after 987721(1043*947) numbers it would return 15 either even-only, odd-only or alternating odd and even numbers? It is a part of an assignment for a long term competition and i've got no idea how to solve it. I don't want the final solution, I'd like to learn how to do it myself.

  • WCF 3.5 - Remove SVC Extension - Special Case

    - by Brandon
    I have several RESTful endpoints like such: System.Security.Role.svc System.Security.User.svc etc. This is meant to be a namespace so our RESTful URL's would look like: /rest/{class namespace}/{actions} I have tried a few examples to get the SVC extension removed when my endpoint has multiple periods in it, however, nothing seems to work. I have tested with the WCF REST Contrib package (http://wcfrestcontrib.codeplex.com/), this example (http://www.west-wind.com/weblog/posts/570695.aspx), and another StackOverflow post (http://stackoverflow.com/questions/355165/how-to-remove-thie-svc-extension-in-restful-wcf-service). This works great when my endpoint is something like this: Echo.svc It will properly remove the SVC extension. Any ideas on how to handle endpoints with multiple periods in the endpoint name? EDIT: After some further testing, I found out that it is failing because whenever you do: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If the endpoint contains multiple periods, it strips off everything after the endpoint causing all of the standard IHttpModule's to fail. Example: If I call http://localhost/services/Echo/test, my relative app file path has a returned value of: ~/echo/test However, if I make a call as http://localhost/services/System.Security.User/test, then my relative app file path has a returned value of: ~/system.security.user I am missing the '/test' on the end in that situation.

  • Special case when calling InvokeScript with the winforms WebBrowser control does not work

    - by wang-min
    I am trying to use InvokeScript method on the WebBrowser control to execute a script on the web page that has been loaded into my WebBrowser control. If I am calling just a simple javascript function, this works properly. However, the javascript function that I am trying to call is nested within a variable like this: var holder = { DoA: function() { .... }, DoB: function() { ..... } } Calling holder.DoA works fine when called from within the javascript, but the function is not called successfully when I try to call it from within my C# code like this: object obj1 = m_webBrowser.Document.InvokeScript("holder.DoA"); Any ideas?

  • Problem with apostrophes and other special characters when using aspell in windows

    - by Loftx
    Hi there, We seem to be having a problem with the spell checker on our content management system where it marks the ve part of We’ve as a misspelling. The spellchecker uses aspell which is called from a script on the server which executes the cmd.exe and uses it to pipe a file into aspell (it's a long winded way I know, but our server side programming langauge (ColdFusion) doesn't support writing to stdin for executables). Aspell is called by executing: c:\windows\system32\cmd.exe /c type d:\path_to_file\file.txt | "C:\Program Files\Aspell\bin\aspell" --lang=en -a Where file.txt contains the text to be spelled e.g. ^Oh have We’ve (the carat is added to prevent piping problems I believe). Aspell then output: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) * * * & ve 62 12: vie, voe, V, v, veg, vet, Be, Ce, be, Ev, E, e, vex, VA, VI, Va, Vi, vi, we, VD, VF, VG, VJ, VP, VT, Vt, vb, vs, DE, De, Fe, GE, Ge, He, IE, Le, ME, Me, NE, Ne, OE, PE, Re, SE, Se, Te, Xe, he, me, re, ye, Ave, Eve, Ive, ave, eve, VAR, var, veer, vier, view, vow However, we have a dev site, with the same version of Aspell, and when the same file is used it outputs with no misspellings. Both servers are running Aspell 0.50.3 on Windows server 2003, but there could be other differences in configuration: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) I'm wondering if the problem is to do with the piping part of the process or something different in the Aspell configuration. Does anyone have any ideas? Cheers, Tom

  • JSP/Servlet CRUD form with special input field based on join table relationship

    - by user1701467
    There's database with a bunch of tables that are joined with join tables. E.g. Members and Division are joined with MembersDivisions table. JSP/Servlet login functionality has been developed, but now the CRUD functionality needs to be implemented and I was unable to find any tutorials about it, especially involving the join table(when creating new division you can add members to it, or add more to the existing one). Maybe someone could, theoretically, explain how to do the Division part of the CRUD web form?
