• Access JavaScript variables with Selenium IDE

  - by kRON

  I'm wondering if it's possible to access page JavaScript variables with Selenium. I have an application that's using a variable attached to the window object. It has a global scope and I can access it either with window._myvar, window['_myvar'], _myvar, this['_myvar'], this._myvar depending on the context. So I tried to get Selenium to echo it. As far as I understand, in Selenium IDE the context in which everything runs is selenium. I tried doing this.browserbot.getCurrentWindow()._myvar, this.browserbot.getCurrentWindow()[_myvar] to no avail. I get bumped with the following error Unexpected Exception: message -> eval(match[1]) is undefined. Anyone managed to access their page's JavaScript?

• Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

  - by jdk

  I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)

• Error: Can't find common super class of ...

  - by PatlaDJ

  I am trying to process with Proguard a MS Windows desktop application (Java 6 SE using the SWT lib provided by Eclipse). And I get the following critical error: Unexpected error while performing partial evaluation: Class = [org/eclipse/swt/widgets/DateTime] Method = [<init>(Lorg/eclipse/swt/widgets/Composite;I)V] Exception = [java.lang.IllegalArgumentException] (Can't find common super class of [java/lang/StringBuffer] and [org/eclipse/swt/internal/win32/TCHAR]) Error: Can't find common super class of [java/lang/StringBuffer] and [org/eclipse/swt/internal/win32/TCHAR] ---------------------------- When I tried to Google the error, it came out only on two spots on the entire web, that astonished me greatly. I am newbie using Proguard and Java code optimization tools at all. Any thoughts and suggestions how to fix this, will be appreciated. Thanks in advance.

• How do I overload an operator for an enumeration in C#?

  - by ChrisHDog

  I have an enumerated type that I would like to define the , <, =, and <= operators for. I know that these operators are implictly created on the basis of the enumerated type (as per the documentation) but I would like to explictly define these operators (for clarity, for control, to know how to do it, etc...) I was hoping I could do something like: public enum SizeType { Small = 0, Medium = 1, Large = 2, ExtraLarge = 3 } public SizeType operator >(SizeType x, SizeType y) { } But this doesn't seem to work ("unexpected toke") ... is this possible? It seems like it should be since there are implictly defined operators. Any suggestions?

• NedMalloc / DlMalloc experiences

  - by Suma

  I am currently evaluating a few of scalable memory allocators, namely nedmalloc and ptmalloc (both built on top of dlmalloc), as a replacement for default malloc / new because of significant contention seen in multithreaded environment. Their published performance seems to be good, however I would like to check what are experiences of other people who have really used them. Were your performance goals satisfied? Did you experience any unexpected or hard to solve issues (like heap corruption)? If you have tried both ptmaalloc and nedmalloc, which of the two would you recommend? Why (ease of use, performance)?

• Spring Security Issue: Controller, Anonymous Requests...

  Hey guys, I have an app that uses Spring security and BlazeDS. Flex 3.2 is used for the client app. Generally client app makes service calls using RemoteObjects.

• Python Fabric error

  I'm running fabric (Django deployment to apache) and everything seems to work fine until I get to the task for installing the site: def install_site(): "Add the virtualhost file to apache" require('release', provided_by=[deploy, setup]) sudo('cd %(path)/releases/%(release)/%(release); cp %(project_name)/%(virtualhost_path)/%(project_domain) /etc/apache2/sites-available/%(project_domain)s') sudo('cd /etc/apache2/sites-available; a2ensite %(project_domain)') I keep getting this error: [173.203.124.16] sudo: cd %(path)/releases/%(release)/%(release); [173.203.124.16] err: /bin/bash: -c: line 0: syntax error near unexpected token `(' [173.203.124.16] err: /bin/bash: -c: line 0: `cd %(path)/releases/%(release)/%(r elease);' Warning: sudo() encountered an error (return code 2) while executing 'cd %(path) /releases/%(release)/%(release);' I've gone through the fabfile.py over and over and I can't see why the error is coming...any ideas?

• Roadblocks in creating a custom operating system

  - by Dinah

  It seems to me that the most common overly ambitious project that programmers (esp. Comp. Sci. grads) try to tackle is building your own operating system. (Trying to create your own programming language + compiler is probably even more common but not nearly as ambitious.) For those (like myself) foolish enough to try: aside from the sheer size, what are the biggest *gotcha*s or unexpected roadblocks you've encountered in trying to create your own OS from the ground up? Edit: A great OS question: http://stackoverflow.com/questions/43180/how-to-get-started-in-operating-system-development/

• Flex 3.5 Accordion and TabNavigator selectedIndex Bug

  - by majgis

  I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Once this behavior has been evoked, even trying to set the selectedIndex programmatically does not end in the desired result. Specifically, if set the selectedIndex to zero (or click on the first tab/header) it might temporarily hop to that index but then will finish on a different index. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

• SSIS- Sharepoint list data transfer issue

  - by Vicky

  Hi , We are trying to transfer data from oracle database (about 60,0000) records only to a sharepoint list using SSIS. But we are getting following error when records reaches around 19000 . The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020 and System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (400) Bad Request. Earlier we thought if could because of Sharepoint list limit so we tried by reducing two of the columns and then it has went fine. So we left with one of the column of Datatype DT_STR and length 400 in oracle beacuse of which issue might be happening, It is mapped to sharepoint custom list field of multiline type. We also verified if length of field is issue but in oracle DB for all records max length for this column is only 239 so length issue is also ruled out. Any one who has faced this kind of issue or knows cause of this issue.Kindly let us know.. Thanks and regards, Vicky

• PHP eval issue with PHP + HTML code

  - by i-CONICA

  Hi, I've got PHP and HTML code stored in a database table. When I get this data, I need to echo the HTML and process the PHP. I thought I could use eval() for this, which works, if I do this eval("echo 'dlsj'; ? EVALED "); I get dlsjEVALED printed out. The problem is, I get a fatal error when I run longer scripts. Things like: Parse error: syntax error, unexpected '<' in /home/content.php(18) : eval()'d code on line 1 Any advice = awesome. Thanks.

• Referencing a union inside a structure using union tag gives incorrect address

  - by AlanKley

  I had a need to declare a union inside a structure as defined below: struct MyStruct { int m_DataType; DWORD m_DataLen; union theData { char m_Buff [_MAX_PATH]; struct MyData m_myData; } m_Data; }; Initially, I tried accessing the union data as follows (before I added the m_Data declaration): MyStruct m_myStruct; char* pBuff = m_myStruct.theData::m_Buff; This compiles but returns to pBuff a pointer to the beginning of the MyStruct structure which caused me to overwrite the m_DataType & m_DataLength members when I thought I was writing to the m_Buff buffer. I am using Visual Studio 2008. Can anyone explain this unexpected behavior? Thanks.

• Google Maps API Geocode gives error "Invalid label" in Firefox

  - by Bennystijn

  Today I struggled with the following: $.ajax({url:'http://maps.google.com/maps/api/geocode/jsonaddress=Karachi&sensor=false&output=json&callback=?', dataType: 'json', success: function(data){ //eval("("+data+")"); alert(data); } }); Firefox gives the error "Invalid Label" and Chrome "Uncaught SyntaxError: Unexpected token :". I found a lot of posts about this, and I tried all kinds of things like eval(), but also: $.getJSON('http://maps.google.com/maps/api/geocode/jsonaddress=Karachi&sensor=false&output=json&callback=?', function(data){ //eval("("+data+")"); alert(data); } ); Same result. Also, other json data works fine, for instance flickr ("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?). So it has something to do with the Google Maps API output i guess.. Thanks in advance.

• Installing sSMTP from SSH

  I'm on a Web Hosting Buzz reseller account. They have some very stringent mail sending rules, including blocking of authenticated SMTP socket mail sending using PEAR. It was suggested in WHB forum that this was possible with sSMTP. I've since gotten SSH access and googled how to install sSMTP from SSH: rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm yum install ssmtp However, the first line fails with: Retrieving http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm error: skipping http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm - transfer failed - Unknown or unexpected error It was a very old thread in WHB forum and the thread poster could not be reached for assistance. Any help would be much appreciated!

• Latent Dirichlet Allocation, pitfalls, tips and programs

  - by Gregg Lind

  I'm experimenting with Latent Dirichlet Allocation for topic disambiguation and assignment, and I'm looking for advice. Which program is the "best", where best is some combination of easiest to use, best prior estimation, fast How do I incorporate my intuitions about topicality. Let's say I think I know that some items in the corpus are really in the same category, like all articles by the same author. Can I add that into the analysis? Any unexpected pitfalls or tips I should know before embarking? I'd prefer is there are R or Python front ends for whatever program, but I expect (and accept) that I'll be dealing with C.

• capture any error in VBScript?

  - by JoelFan

  I have a batch file that calls a VBScript (.vbs) program. After calling it, my batch script checks errorlevel to see if the .vbs program failed. I can signal failure with an exit code in the .vbs program with WScript.Quit(1). However, I can only do that explicitly. If some unexpected run-time error happens, the .vbs quits with an error dialog box, however the exit code is zero so my batch file thinks it suceeded! How can I change that behavior? And if you are thinking of saying, use on error goto, don't bother... that syntax is available in regular VB, but not in VBScript.

• iphone OCMockObject and unit-testing a class that inherits from NSURLConnection

  - by Justin Galzic

  I want to unit test the custom init method of a class that inherits from NSURLConnection -- how would I do this if the init of my testable class invokes NSURLConnection's initWithRequest? I'm using OCMock and normally, I can mock objects that are contained within my test class. For this inheritance scenario, what's the best approach to do this? - (void)testInit { id urlRequest = [OCMockObject mockForClass:[NSURLRequest class]]; MyURLConnectionWrapper *conn = [[MyURLConnectionWrapper alloc] initWithRequest:urlRequest delegate:self someData:extraneousData]; } My class is implemented like this: @interface MyURLConnectionWrapper : NSURLConnection { } - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData @end @implementation MyURLConnectionWrapper - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData { if (self = [super initWithRequest:request delegate:delegate]) { // do some additional work here } return self; } Here's the error I get: OCMockObject[NSURLRequest]: unexpected method invoked: _CFURLRequest
