• SVN authz, path-based authentication woes

  - by Ronny

  [groups] developer = a,b,c doc = r,x [/doc] @doc = rw @developer = rw [/] @developer = rw * = If now a member of the group doc tries to check out the documentation, it does not work. I want members of doc just to be able to check out the sub-dir doc, anything else is forbidden. Any ideas howto achieve this? kind regards ronny [update] client: svn, version 1.5.4 (r33841) server: svn, Version 1.4.6 (r28521) access via svn+ssh:/user@host/fullpath-to-repos 1 perfectly works for two years 2 might be - see version numbers above (I'll contant our admin, immediatelly) 3 no? just ssh 4 nope 5 nope [update] using client version svn 1.4.6 (r28521) does not work either - same errors I use plain command line access. svn co svn+ssh://....

• Relative paths in spring classpath resource

  - by Mike Q

  Hi all, I have a bunch of spring config files, all of which live under the META-INF directory in various subpackages. I have been using import like the following... <import resource="../database/schema.xml"/> So a relative path from the source file. This works fine when I am working with a local build outside of a jar file. But when I package everything up in a jar then I get an error that it cannot resolve the URL resource. If I change the above to an absolute path (with classpath:) then it works fine. Is there any way to use relative paths with ".." in when the configs are packaged in a jar or am I restricted to descending relative paths and absolute paths only? Thanks.

• Using A Local file path in a Streamwriter object ASP.Net

  - by Nick LaMarca

  I am trying to create a csv file of some data. I have wrote a function that successfully does this.... Private Sub CreateCSVFile(ByVal dt As DataTable, ByVal strFilePath As String) Dim sw As New StreamWriter(strFilePath, False) ''# First we will write the headers. ''EDataTable dt = m_dsProducts.Tables[0]; Dim iColCount As Integer = dt.Columns.Count For i As Integer = 0 To iColCount - 1 sw.Write(dt.Columns(i)) If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) ''# Now write all the rows. For Each dr As DataRow In dt.Rows For i As Integer = 0 To iColCount - 1 If Not Convert.IsDBNull(dr(i)) Then sw.Write(dr(i).ToString()) End If If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) Next sw.Close() End Sub The problem is I am not using the streamwriter object correctly for what I trying to accomplish. Since this is an asp.net I need the user to pick a local filepath to put the file on. If I pass any path to this function its gonna try to write it to the directory specified on the server where the code is. I would like this to popup and let the user select a place on their local machine to put the file.... Dim exData As Byte() = File.ReadAllBytes(Server.MapPath(eio)) File.Delete(Server.MapPath(eio)) Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", fn)) Response.ContentType = "application/x-msexcel" Response.BinaryWrite(exData) Response.Flush() Response.End() I am calling the first function in code like this... Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H() CreateCSVFile(emplTable, "C:\\EmplTable.csv") Where I dont want to have specify the file loaction (because this will put the file on the server and not on a client machine) but rather let the user select the location on their client machine. Can someone help me put this together? Thanks in advance.

• Java Math.cos() Method Does Not Return 0 When Expected

  - by dimo414

  Using Java on a Windows 7 PC (not sure if that matters) and calling Math.cos() on values that should return 0 (like pi/2) instead returns small values, but small values that, unless I'm misunderstanding, are much greater than 1 ulp off from zero. Math.cos(Math.PI/2) = 6.123233995736766E-17 Math.ulp(Math.cos(Math.PI/2)) = 1.232595164407831E-32 Is this in fact within 1 ulp and I'm simply confused? And would this be an acceptable wrapper method to resolve this minor inaccuracy? public static double cos(double a){ double temp = Math.abs(a % Math.PI); if(temp == Math.PI/2) return 0; return Math.cos(a); }

• how subsonic SP should return a value

  - by android.sm

  Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

• TinyMce imagemanager won't generate image path when used with an iframe

  - by Tom

  I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

• Web Deployment Project failed to map path for include virtual

  - by Duke

  I am building my site with a web deployment project but the build fails with a number of errors all relating to the "#include virtual" directives in my master page. The includes are necessary to import a set of centrally managed html template files. Here is an example of the include directive and associated error: <!-- #include virtual="/v3/sits/pdpdev/assets-templates/inc/head.html" --> /PDPRegistration.csproj/Pages/ContentPage.Master(15): error ASPPARSE: Failed to map the path '/v3/sits/pdpdev/assets-templates/inc/head.html'. The error for each included file actually appears multiple times. I'm not sure what is being mapped or why, but this was never a problem until I started using WDP (which I wanted to alter web.config depending on the build environment, among other things.) The project is built locally on my PC and then copied to the web server via a mapped drive. I found a few solutions on the 'net involving IIS metabase - they weren't quite clear to me, and I'm not sure if they apply given how I build and deploy the project (that is, would I have to build on the same system as IIS in order to make use of the metabase?) Can anyone suggest how I can get my project to build with WDP?

• How to return all aspnet_compiler errors (not just those in first directory)

  - by Dan Atkinson

  Hi there! Is there a way to get the aspnet_compiler to go through all views and return all errors, rather than just the errors in the current view directory? For example, lets say I have a project that has a bunch of folders... Views Folder1 Folder2 Folder3 Folder4 Two of them (Folder2 and Folder3) have errors. aspnet_compiler will run, and only return the errors it comes across in Folder2. It won't return those in Folder3 at the same time. Once I fix the errors in Folder2 and run it again, it'll then pick up the ones in the Folder3. I fix those. And then have to run the tool again, and again until it's all fixed. This is getting annoying!! For reference, here's the command I use: C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v / -p "C:\path\to\project" Thanks in advance!

• Ruby Methods: how to return an usage string when insufficient arguments are given

  - by Shyam

  Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

• g++ How to get warning on ignoring function return value

  - by ArunSaha

  lint produces some warning like: foo.c XXX Warning 534: Ignoring return value of function bar() From the lint manual 534 Ignoring return value of function 'Symbol' (compare with Location) A function that returns a value is called just for side effects as, for example, in a statement by itself or the left-hand side of a comma operator. Try: (void) function(); to call a function and ignore its return value. See also the fvr, fvo and fdr flags in §5.5 "Flag Options". I want to get this warning, if there exists any, during compilation. Is there any option in gcc/g++ to achieve this? I had turned on -Wall but that apparently did not detect this.

• Should I make OR operator to return const reference or just reference

  - by Yan Cheng CHEOK

  class error_code { public: error_code() : hi(0), lo(0) {} error_code(__int64 lo) : hi(0), lo(lo) {} error_code(__int64 hi, __int64 lo) : hi(hi), lo(lo) {} error_code& operator|=(const error_code &e) { this->hi |= e.hi; this->lo |= e.lo; return *this; } __int64 hi; __int64 lo; }; error_code operator|(const error_code& e0, const error_code& e1) { return error_code(e0.hi | e1.hi, e0.lo | e1.lo); } int main() { error_code e0(1); error_code e1(2); e0 |= e1; } I was wondering, whether I should make operator|= to return a const error_code& or error_code& ?

• ASP.Net MVC, JS injection and System.ArgumentException - Illegal Characters in path

  - by Mose

  Hi, In my ASP.Net MVC application, I use custom error handling. I want to perform custom actions for each error case I meet in my application. So I override Application_Error, get the Server.GetLastError(); and do my business depending on the exception, the current user, the current URL (the application runs on many domains), the user IP, and many others. Obviousely, the application is often the target of hackers. In almost all the case it's not a problem to detect and manage it, but for some JS URL attacks, my error handling does not perform what I want it to do. Ex (from logs) : http://localhost:1809/Scripts/]||!o.support.htmlSerialize&&[1 When I got such an URL, an exception is raised when accessing the ConnectionStrings section in the web.config, and I can't even redirect to another URL. It leads to a "System.ArgumentException - Illegal Characters in path, etc." The screenshot below shows the problem : http://screencast.com/t/Y2I1YWU4 An obvious solution is to write a HTTP module to filter the urls before they reach my application, but I'd like to avoid it because : I like having the whole security being managed in one place (in the Application_Error() method) In the module I cannot access the whole data I have in the application itself (application specific data I don't want to debate here) Questions : Did you meet this problem ? How did you manage it ? Thanks for you suggestions, Mose

• Relative links in CSS, after moving Wordpress

  - by bozdoz

  I created a blog with Wordpress on a temporary test domain. I put it in the main directory, not a folder. Now I want to move it to the correct website, in a folder. I can update all of the MySQL values for the site URL, and the relative path links work just fine. The problem is that I can't seem to make my CSS path links work. I realize that my problem is that they are relative to the CSS file, in the WordPress theme, and not the page. But how can I fix this? Here is an example: #topNav {background:#3a93c3 url(wp-content/uploads/2011/07/blueNav.jpg) repeat-x;} I have tried adding './', '../', and '../../' to the beginning, but it doesn't work at all. Any suggestions?

• Python `.pth` files and using relative paths

  - by kRON

  I have a lot of development versions of packages installed with virtualenv under the default /src directory in the environment. Normally, I decided to do the development of my project under the /src directory afterwards. To add my directory to the Python path, I decided to eschew from using any absolute paths, since I'm going to have to move the project around with my friends. It's a Django application, so I was happy with putting environment.pth under the root that contained the path to my project and a wsgi in the same directory would call the sites module to parse environment.pth. All good. I was also looking to move the .pth file into site-packages, but I'm having trouble with relative paths that move up the directory tree. For: /env /lib /site-pacakges /src /myproject So, the .pth entry in site-packages to myproject should look like ../../src/myproject, but this doesn't seem to be working for me on Windows.

• return first non repeating character in a string

  - by Amm Sokun

  I had to solve this question in which given a string, i had to return the first non repeating character present in the string. I solved it using hashtable and wrote a method which takes a constant reference to the string and returns the first non repeating character. However, when there is no non repeating character present in the string, i return -1 and in the main program i check as follows char c = firstNonRepeating( word ); if (static_cast<int> (c) == -1) cout<<"no non repeating character present\n"; else cout<<c<<endl; is that the correct way to return -1 when required character is not present?

• Returning a ReadOnlyCollection from a method with an IList return type

  - by devoured elysium

  Here I have the following bit of code: private IList<IState> _states = new List<IState>(); private ReadOnlyCollection<IState> _statesViewer; public IList<IState> States { get { return _statesViewer; } } Generally it is preferable to return interfaces than the concrete classes themselves, but in this case, shouldn't I set as the return type of the States property a ReadOnlyCollection? Any user of my library will think it is possible to anything you can do with an IList if I set it as so, and that means adding elements. That is not true and I'm definitely breaking the contract exposing it as an IList. Am I right with this view or there is something else I am missing here?

• LINQ to sql return group by results from method

  - by petebob796

  How do I create a method to return the results of a group by in LINQ to sql such as the one below: internal SomeTypeIDontKnow GetDivisionsList(string year) { var divisions = from p in db.cm_SDPs where p.acad_period == year group p by new { p.Division } into g select new { g.Key.Division }; return divisions; } I can't seem to define a correct return type. I think it is because it's an anonymous type but haven't got my head around it yet. Do I need to convert it to a list or something? The results would just be used for filling a combo box.

• Calculating Divergent Paths on Subtending Rings

  - by Russ

  I need to calculate two paths from A to B in the following graph, with the constraint that the paths can't share any edges: hmm, okay, can't post images, here's a link. All edges have positive weights; for this example I think we can assume that they're equal. My naive approach is to use Djikstra's algorithm to calculate the first path, shown in the second graph in the above image. Then I remove the edges from the graph and try to calculate the second path, which fails. Is there a variation of Djikstra, Bellman-Ford (or anything else) that will calculate the paths shown in the third diagram above? (Without special knowledge and removal of the subtending link, is what I mean)

I did that and the compiler didn't complain... could someone please explain? class MyBaseClass { int value; public: virtual int getValue() = 0; }; class MyClass : public MyBaseClass { double value; public: virtual double getValue(); // here!!! return is double, not int }; double MyClass::getValue() { return this->value; } The compiler totally accepted something similar (MSVC und MinGW)... could anyone please exaplain to what extent this is legal?

• Optimizing Dijkstra for dense graph?

  - by Jason

  Is there another way to calculate the shortest path for a near complete graph other than Dijkstra? I have about 8,000 nodes and about 18 million edges. I've gone through the thread "a to b on map" and decided to use Dijkstra. I wrote my script in Perl using the Boost::Graph library. But the result isn't what I expected. It took about 10+ minutes to calculate one shortest path using the call $graph-dijkstra_shortest_path($start_node,$end_node); I understand there are a lot of edges and it may be the reason behind the slow running time. Am I dead in the water? Is there any other way to speed this up?

• How to import a module from a directory?

  - by Roman

  On my system I have two versions of Python (to call them I type python and python2 in the command line). When I use the first version of Python, I cannot import sklearn module but I can do it in the second version of Python. I would like to use the first version of python (because other modules are available there) and, at the same time, I would like to be able to import sklearn from this version of Python. My solution was to use: import sys sys.path.append('location_of_the_sklearn_module') To find the location of the sklearn module I started a python session (using the second version of python, in which sklearn works). The I type: import sklearn sklearn.__file__ As a result I got: /home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn/__init__.pyc In the session of the first version of Python I tried: import sys sys.path.append('/home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn') import sklearn Unfortunately it did not work. As a result I got: ImportError: No module named sklearn Does anybody know what I am doing wrong and if it is possible to reach the goal in the way I try?

• Aggregate path counts using HierarchyID

  - by austincav

  Business problem - understand process fallout using analytics data. Here is what we have done so far: Build a dictionary table with every possible process step Find each process "start" Find the last step for each start Join dictionary table to last step to find path to final step In the final report output we end up with a list of paths for each start to each final step: User Fallout Step HierarchyID.ToString() A 1/1/1 B 1/1/1/1/1 C 1/1/1/1 D 1/1/1 E 1/1 What this means is that five users (A-E) started the process. Assume only User B finished, the other four did not. Since this is a simple example (without branching) we want the output to look as follows: Step Unique Users 1 5 2 5 3 4 4 2 5 1 The easiest solution I could think of is to take each hierarchyID.ToString(), parse that out into a set of subpaths, JOIN back to the dictionary table, and output using GROUP BY. Given the volume of data, I'd like to use the built-in HierarchyID functions, e.g. IsAncestorOf. Any ideas or thoughts how I could write this? Maybe a recursive CTE?
