• ICalendar not readable by google calendar.

  - by Sagar

  Operating system : WinXP Program and version you use to access Google Calendar (FF3.5): I'm developing a script (based on an existing vCal ASP.NET class I found online) to generate an .ics file. This file works perfectly when importing to Outlook 2003. When I try to import to Google Calendar, I get the following error: Failed to import events: Unable to process your iCal/CSV file.. I don't know too much about the vCal format or syntax, but everything looks fine to me. I'll post the sample test calendar .ics below: BEGIN:VCALENDAR PRODID:-//jpalm.se//iCalendar example with ASP.NET MVC//EN VERSION:2.0 CALSCALE:GREGORIAN METHOD:PUBLISH X-MS-OLK-FORCEINSPECTOROPEN:TRUE BEGIN:VEVENT DTSTART:20100304T000000Z DTEND:20100304T000000Z TRANSP:OPAQUE SEQUENCE:0 UID:7c9d6dd7-41f2-4171-8ae4-35820974efa4 DESCRIPTION:uba:Project20100321:sagar .

• jQuery .load() XHTML issue

  - by Urfe

  I am having some strange problems loading content from another XHTML page via jQuery. When the second page I try to load from is served as XHTML I get the below error. I don't know if it helps but both documents validate when I get the error. Uncaught Error: NO_MODIFICATION_ALLOWED_ERR: DOM Exception 7 Currently the header on the second page I load from is: <?xml version="1.0" encoding="iso-8859-1" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <meta name="language" content="en" /> <title>some title</title> <!-- CSS & Javascript included here --> </head> The content type is set as: application/xhtml+xml;charset=iso-8859-1 Interestingly, when I remove all the XHTML stuff from the header and stop setting the content type the error does not occur and everything works great. The load process currently looks like the below. It works fine when everything is plain HTML. $('#overpage').find(".wrap").load(this.getTrigger().attr("href")+" #op").show(); I'm curious why the process only does not work when the second page I load from is XHTML. I don't want to serve the page as just plain HTML and am looking for advice on what I am doing wrong. Both pages validate and I'm really scratching my head here. Many thanks!

• Embedding swank-clojure in java program

  - by user237417

  Based on the Embedding section of http://github.com/technomancy/swank-clojure, I'm using the following to test it out. Is there a better way to do this that doesn't use Compiler? Is there a way to programmatically stop swank? It seems start-repl takes control of the thread. What would be a good way to spawn off another thread for it and be able to kill that thread programatically. import clojure.lang.Compiler; import java.io.StringReader; public class Embed { public static void main(String[] args) throws Exception { final String startSwankScript = "(ns my-app\n" + " (:use [swank.swank :as swank]))\n" + "(swank/start-repl) "; Compiler.load(new StringReader(startSwankScript)); } } Any help much appreciated, hhh

• Run bat file in Java and wait 2

  - by Savvas Dalkitsis

  This is a followup question to my other question : http://stackoverflow.com/questions/2434125/run-bat-file-in-java-and-wait The reason i am posting this as a separate question is that the one i already asked was answered correctly. From some research i did my problem is unique to my case so i decided to create a new question. Please go read that question before continuing with this one as they are closely related. Running the proposed code blocks the program at the waitFor invocation. After some research i found that the waitFor method blocks if your process has output that needs to be proccessed so you should first empty the output stream and the error stream. I did those things but my method still blocks. I then found a suggestion to simply loop while waiting the exitValue method to return the exit value of the process and handle the exception thrown if it is not, pausing for a brief moment as well so as not to consume all the CPU. I did this: import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class Test { public static void main(String[] args) { try { Process p = Runtime.getRuntime().exec( "cmd /k start SQLScriptsToRun.bat" + " -UuserName -Ppassword" + " projectName"); final BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); final BufferedReader error = new BufferedReader(new InputStreamReader(p.getErrorStream())); new Thread(new Runnable() { @Override public void run() { try { while (input.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); new Thread(new Runnable() { @Override public void run() { try { while (error.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); int i = 0; boolean finished = false; while (!finished) { try { i = p.exitValue(); finished = true; } catch (IllegalThreadStateException e) { e.printStackTrace(); try { Thread.sleep(500); } catch (InterruptedException e1) { e1.printStackTrace(); } } } System.out.println(i); } catch (IOException e) { e.printStackTrace(); } } } but my process will not end! I keep getting this error: java.lang.IllegalThreadStateException: process has not exited Any ideas as to why my process will not exit? Or do you have any libraries to suggest that handle executing batch files properly and wait until the execution is finished?

• Problem's running unittest test suite OO

  - by chrissygormley

  Hello, I have a test suite to perform smoke tests. I have all my script stored in various classes but when I try and run the test suite I can't seem to get it working if it is in a class. The code is below: (a class to call the tests) from alltests import SmokeTests class CallTests(SmokeTests): def integration(self): self.suite() if __name__ == '__main__': run = CallTests() run.integration() And the test suite: class SmokeTests(): def suite(self): #Function stores all the modules to be tested modules_to_test = ('external_sanity', 'internal_sanity') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests unittest.main(defaultTest='suite') This output's an error: Attribute Error: 'module' object has no attribute 'suite' So I can see how to call a normal function defined but I'm finding it difficult calling in the suite. In one of the tests the suite is set up like so: class InternalSanityTestSuite(unittest.TestSuite): # Tests to be tested by test suite def makeInternalSanityTestSuite(): suite = unittest.TestSuite() suite.addTest(TestInternalSanity("BasicInternalSanity")) suite.addTest(TestInternalSanity("VerifyInternalSanityTestFail")) return suite def suite(): return unittest.makeSuite(TestInternalSanity) Can anyone help me with getting this running? Thanks for any help in advance.

• Creating a tiled map with blender

  - by JamesB

  I'm looking at creating map tiles based on a 3D model made in blender, The map is 16 x 16 in blender. I've got 4 different zoom levels and each tile is 100 x 100 pixels. The entire map at the most zoomed out level is 4 x 4 tiles constructing an image of 400 x 400. The most zoomed in level is 256 x 256 obviously constructing an image of 25600 x 25600 What I need is a script for blender that can create the tiles from the model. I've never written in python before so I've been trying to adapt a couple of the scripts which are already there. So far I've come up with a script, but it doesn't work very well. I'm having real difficulties getting the tiles to line up seamlessly. I'm not too concerned about changing the height of the camera as I can always create the same zoomed out tiles at 6400 x 6400 images and split the resulting images into the correct tiles. Here is what I've got so far... #!BPY """ Name: 'Export Map Tiles' Blender: '242' Group: 'Export' Tip: 'Export to Map' """ import Blender from Blender import Scene,sys from Blender.Scene import Render def init(): thumbsize = 200 CameraHeight = 4.4 YStart = -8 YMove = 4 XStart = -8 XMove = 4 ZoomLevel = 1 Path = "/Images/Map/" Blender.drawmap = [thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path] def show_prefs(): buttonthumbsize = Blender.Draw.Create(Blender.drawmap[0]); buttonCameraHeight = Blender.Draw.Create(Blender.drawmap[1]) buttonYStart = Blender.Draw.Create(Blender.drawmap[2]) buttonYMove = Blender.Draw.Create(Blender.drawmap[3]) buttonXStart = Blender.Draw.Create(Blender.drawmap[4]) buttonXMove = Blender.Draw.Create(Blender.drawmap[5]) buttonZoomLevel = Blender.Draw.Create(Blender.drawmap[6]) buttonPath = Blender.Draw.Create(Blender.drawmap[7]) block = [] block.append(("Image Size", buttonthumbsize, 0, 500)) block.append(("Camera Height", buttonCameraHeight, -0, 10)) block.append(("Y Start", buttonYStart, -10, 10)) block.append(("Y Move", buttonYMove, 0, 5)) block.append(("X Start", buttonXStart,-10, 10)) block.append(("X Move", buttonXMove, 0, 5)) block.append(("Zoom Level", buttonZoomLevel, 1, 10)) block.append(("Export Path", buttonPath,0,200,"The Path to save the tiles")) retval = Blender.Draw.PupBlock("Draw Map: Preferences" , block) if retval: Blender.drawmap[0] = buttonthumbsize.val Blender.drawmap[1] = buttonCameraHeight.val Blender.drawmap[2] = buttonYStart.val Blender.drawmap[3] = buttonYMove.val Blender.drawmap[4] = buttonXStart.val Blender.drawmap[5] = buttonXMove.val Blender.drawmap[6] = buttonZoomLevel.val Blender.drawmap[7] = buttonPath.val Export() def Export(): scn = Scene.GetCurrent() context = scn.getRenderingContext() def cutStr(str): #cut off path leaving name c = str.find("\\") while c != -1: c = c + 1 str = str[c:] c = str.find("\\") str = str[:-6] return str #variables from gui: thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path = Blender.drawmap XMove = XMove / ZoomLevel YMove = YMove / ZoomLevel Camera = Scene.GetCurrent().getCurrentCamera() Camera.LocZ = CameraHeight / ZoomLevel YStart = YStart + (YMove / 2) XStart = XStart + (XMove / 2) #Point it straight down Camera.RotX = 0 Camera.RotY = 0 Camera.RotZ = 0 TileCount = 4**ZoomLevel #Because the first thing we do is move the camera, start it off the map Camera.LocY = YStart - YMove for i in range(0,TileCount): Camera.LocY = Camera.LocY + YMove Camera.LocX = XStart - XMove for j in range(0,TileCount): Camera.LocX = Camera.LocX + XMove Render.EnableDispWin() context.extensions = True context.renderPath = Path #setting thumbsize context.imageSizeX(thumbsize) context.imageSizeY(thumbsize) #could be put into a gui. context.imageType = Render.PNG context.enableOversampling(0) #render context.render() #save image ZasString = '%s' %(int(ZoomLevel)) XasString = '%s' %(int(j+1)) YasString = '%s' %(int((3-i)+1)) context.saveRenderedImage("Z" + ZasString + "X" + XasString + "Y" + YasString) #close the windows Render.CloseRenderWindow() try: type(Blender.drawmap) except: #print 'initialize extern variables' init() show_prefs()

• Are xlrd and xlwt compatible?

  - by Leo

  I'm trying to create a workbook with python and I need to test the values of different cells to fill it but I'm having some troubles. I use xlrd and xlwt to create and edit the excel file. I've made a little example of my problem and I don't understand why it's not working. import xlwt import xlrd wb = xlwt.Workbook() ws = wb.add_sheet('Test') ws.write(0,0,"ah") cell = ws.cell(0,0) # AttributeError: 'Worksheet' object has no attribute 'cell' print cell.value I had taken for granted that xlrd and xlwt have shared classes which can interact with each other but it doesn't seem to be the case. How do I get the cell value of an open Worksheet object?

• Can FPDF/FPDI use a PDF in landscape format as a template?

  - by Jim OHalloran

  I am trying to import an existing PDF as a template with FPDI. The template is in landscape format. If I import the template into a new document the template page is inserted in portrait form with the content rotated 90 degrees. If my new document is in portrait the full content appears, but if the new document is also landscape, the content is cropped. Is it possible to use a landscape template with FPDI? Thanks in advance!

• What is the scope of xsl apply-imports?

  - by calavera.info

  My original idea about apply-imports was that if there are two templates which matches the same node, then using apply-imports in a template with higher priority runs the template with the lower priority. But I recently find out that it's important how are imports organized. Two cases interests me particularly. Will apply imports work on a template which is imported in imported file (nested import)? How about a "sibling import" (master file imports two files with templates matching the same nodes) It seems to me that this is not clearly described in specification. Could someone provide authoritative guidelines? EDIT: I can try those cases on my own, but there is always a danger that it will be implementation specific behavior.

• Use spring tag in XSLT

  - by X-Pippes

  I have a XSL/XML parser to produce jsp/html code. Using MVC model I need to accees spring library in order to perform i18n translation. Thus, given the xml <a> ... <country>EN</country> ... </a> and using <spring:message code="table_country_code.EN"/> tag, choose based on the browser language, the transalation into England, Inglaterra, etc... However, the XSL do not support <spring:message> tag. The idea is to have a XSLT with something like this <spring:message code="table_country_code.><xsl:value-of select="country"/>"/>` I also tried to create the spring tag in Java when I make a parse to create the XML but I sill have the same error. ERROR [STDERR] (http-0.0.0.0-8080-1) file:///C:/Software/Jboss/jboss-soa-p-5/jboss-as/bin/jstl:; Line #5; Column #58; The prefix "spring" for element "spring:message" is not bound.

• How to generating comments in hbm2java created POJO?

  - by jschoen

  My current setup using hibernate uses the hibernate.reveng.xml file to generate the various hbm.xml files. Which are then turned into POJOs using hbm2java. We spent some time while designing our schema, to place some pretty decent descriptions on the Tables and there columns. I am able to pull these descriptions into the hbm.xml files when generating them using hbm2jhbmxml. So I get something similar to this: <class name="test.Person" table="PERSONS"> <comment>The comment about the PERSONS table.</comment> <property name="firstName" type="string"> <column name="FIRST_NAME" length="100" not-null="true"> <comment>The first name of this person.</comment> </column> </property> <property name="middleInitial" type="string"> <column name="MIDDLE_INITIAL" length="1"> <comment>The middle initial of this person.</comment> </column> </property> <property name="lastName" type="string"> <column name="LAST_NAME" length="100"> <comment>The last name of this person.</comment> </column> </property> </class> So how do I tell hbm2java to pull and place these comments in the created Java files? I have read over this about editing the freemarker templates to change the way code is generated. I under stand the concept, but it was not to detailed about what else you could do with it beyond there example of pre and post conditions.

• Haskell: Left-biased/short-circuiting function

  - by user2967411

  Two classes ago, our professor presented to us a Parser module. Here is the code: module Parser (Parser,parser,runParser,satisfy,char,string,many,many1,(+++)) where import Data.Char import Control.Monad import Control.Monad.State type Parser = StateT String [] runParser :: Parser a -> String -> [(a,String)] runParser = runStateT parser :: (String -> [(a,String)]) -> Parser a parser = StateT satisfy :: (Char -> Bool) -> Parser Char satisfy f = parser $ \s -> case s of [] -> [] a:as -> [(a,as) | f a] char :: Char -> Parser Char char = satisfy . (==) alpha,digit :: Parser Char alpha = satisfy isAlpha digit = satisfy isDigit string :: String -> Parser String string = mapM char infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a (+++) = mplus many, many1 :: Parser a -> Parser [a] many p = return [] +++ many1 p many1 p = liftM2 (:) p (many p) Today he gave us an assignment to introduce "a left-biased, or short-circuiting version of (+++)", called (<++). His hint was for us to consider the original implementation of (+++). When he first introduced +++ to us, this was the code he wrote, which I am going to call the original implementation: infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a p +++ q = Parser $ \s -> runParser p s ++ runParser q s I have been having tons of trouble since we were introduced to parsing and so it continues. I have tried/am considering two approaches. 1) Use the "original" implementation, as in p +++ q = Parser $ \s - runParser p s ++ runParser q s 2) Use the final implementation, as in (+++) = mplus Here are my questions: 1) The module will not compile if I use the original implementation. The error: Not in scope: data constructor 'Parser'. It compiles fine using (+++) = mplus. What is wrong with using the original implementation that is avoided by using the final implementation? 2) How do I check if the first Parser returns anything? Is something like (not (isNothing (Parser $ \s - runParser p s) on the right track? It seems like it should be easy but I have no idea. 3) Once I figure out how to check if the first Parser returns anything, if I am to base my code on the final implementation, would it be as easy as this?: -- if p returns something then p <++ q = mplus (Parser $ \s -> runParser p s) mzero -- else (<++) = mplus Best, Jeff

• How to create an Intellij and Eclipse compatible code style and code formatting configuration (for j

  - by user141634

  Few weeks ago I tried Intellij and I found it really awesome. Now, at my project there's two programmers (including me) using Intellij and few other programmers gonna still be using Eclipse. Since this project is already very large and it gonna be growing a lot, we need to use compatible Code Style and Code Formatting between Intellij and Eclipse. We do not want to have problems when one user edit one file and reformat it before save. With Eclipse "alone" we used to have some exported configuration, and before anybody starts to work, the first step is just to import this configuration. We already tried to use External Code Formatter, but it didn't work on Intellij 9. So, I have a bunch of questions here: 1 - Is there any way to import eclipse formatting configuration on Intellij 9? 2 - Anybody could share their experience managing this kind of situation? Do you guys have any other suggestion to manage this situation?

• Haskell: how to get through 'no instance for' ?

  - by artemave

  I am learning Haskell. I am on the 8th chapter of this book. The main thing I've learned so far is that Haskell is very unfriendly to me and it bites my ass where possible. Moreover... Heck!

To my best understanding, Text.Regex.Posix.String provides instances for RegexLike Regex String and RegexMaker Regex CompOption ExecOption String, so it should work. On the other hand, I can see that regex in the error message is type variable, not a concrete type, so, perhaps not... Anyway, this is where I am stuck. May be there is a common pattern for resolving no instance for type of problems? Or, in Haskell terms, instance of SmartGuess typeclass for no instance for?

• Trying to understand Java Classloading

  - by Jens

  Hello, I'm currently getting to know Java and OSGi, so I've read a few books. In one particular book the class loading is described. You can download it (free and legal) from the authors page (Neil Bartlett): OSGi Book On page 9 and 10 are this pictures: It seems like there is the possibility that our class "Foo" won't use the class "Bar" of foobar.jar, but instead class "Bar" from naughty.jar. Because of the flat and global structure of the Java classpath this could be, but as far as I know you would define a package from where you want to import a certain class: import foobar.Bar This should prevent loading the wrong class, shouldn't it? Of course assuming that the package is called "foobar".

• Xpages - Get number of active sessions

  - by Jairo

  How do I get the number of active sessions in Xpage. I'm trying to use managed beans but it just returns a weird string. Here's the simple code: import javax.servlet.http.HttpSessionEvent; import javax.servlet.http.HttpSessionListener; public class SessionCounterListener implements HttpSessionListener { private static int totalActiveSessions; public static int getTotalActiveSessions(){ return totalActiveSessions | 0; } public void sessionCreated(HttpSessionEvent arg0) { totalActiveSessions++; System.out.println("sessionCreated - add one session into counter"); } public void sessionDestroyed(HttpSessionEvent arg0) { totalActiveSessions--; System.out.println("sessionDestroyed - deduct one session from counter"); } } I got this from here. But when I call SessionCounterListener.getTotalActiveSessions(), it only returns a weird string, example com.gs3.beans.SessionCounterListener@46c446c4. Please help me. Thanks a lot!

• How to implement ctypes in IronPython

  I need help. I have a code which is passing a script into a DLL and initialize the instrument. But, one of the code unable to use in IronPython beside python 2.7 and 3.3 I have attached the code as below enter code here import ctypes import time, sys DLLHANDLE=ctypes.cdll.LoadLibrary("C:\\INSTRDLL\\builds\\DCSOURCEDLL\\B2902A.dll") INPUTSCRIPT="SYSTEM{DCSOURCE1|INIT}" INPUTVOLTAGE=0.0 c_INPUTSCRIPT=ctypes.c_char_p(INPUTSCRIPT) c_INPUTVOLTAGE=ctypes.c_double(INPUTVOLTAGE) SOURCEHANDLE=DLLHANDLE.DCSOURCE(c_INPUTSCRIPT,c_INPUTVOLTAGE) time.sleep(1) Once "SOURCEHANDLE=DLLHANDLE.DCSOURCE(c_INPUTSCRIPT,c_INPUTVOLTAGE)" is triggered, Ironpython will crash automatically and no idea how to resolve it... or any workaround solution?

• javascript - catch SyntaxError and run alternate function

  - by ludicco

  Hello there, I'm trying to build something on javascript that I can have an input that can be everything like string, xml, javascript and (non-javascript string without quotes) as follows: //strings eval("'hello I am a string'"); /* note the following proper quote marks */ //xml eval(<p>Hello I am a XML doc</p>); //javascript eval("var hello = 2+2;"); So this first 3 are working well since they are simple javascript native formats but when I try use this inside javascript //plain-text without quotes eval("hello I am a plain text without quotes"); //--SyntaxError: missing ; before statement:--// Obviously javascript interprets this as syntax error because it thinks its javascript throwing a SyntaxError. So what I would like to do it to catch this error and perform the adjustment method if this occurs. I've already tried with try catch but it doesn't work since it keeps returning the Syntax error as soon as it tries to execute the code. Any help would be much appreciated Cheers :) Additional Information: Imagine an external file that javascript would read, using spidermonkey, so it's a non-browser stuff(I can't use HttpRequest, DOM, etc...)..not sure if this matters, but there it is. :)

  I've written an RSS feed parser in Java (running on Android) and it parses some feeds perfectly, and others not at all.

• Parsing plain Win32 PE File (Exe/DLL) in C#.NET

  - by Usman

  Hello, I need to parse plain Win32 DLL/Exe and need to get all imports and exports from it and to show it on console or GUI(say Win Forms). Is it possible to parse Win32 DLL/Exe in C#.NET, read its export table,import table and get managed types from it. As its unmanaged PE(.NET doesn't allows you to convert unmanaged PE files to managed .NET assemblies, only it generates COM managed assemblies). So how to parse export and import tables of PE files and take all methods(signatures from it) in managed form.(e.g if char* as argument, it should display as IntPtr) Regards Usman
