• Sources from referenced projects are not deployed to Tomcat in Eclipse

  - by Steven De Groote

  Hi, I have setup a dynamic web project in eclipse with JSF in which I trust on code from another project (framework). Therefore, I added the framework project to the build path of the website project. So far so good, Eclipse recognises every class and the project builds without errors. Problem is though that when I do "run on server" to test it on tomcat 6.0.24, the application fails. I get ClassNotFoundException on every class from the framework project. Is this a bug or is some specific configuration necessary for this?

• [Ruby] Confirm existance of executable (script, bat, cmd, exe) via a ruby file.

  - by srcspider

  Using a ruby file (or any rake facility) I need to find out if the user who executes my script is able to execute certain shell commands. In particular g++ etc. Hopefully system independent so if there is some g++.bat, g++.exe or just g++ (etc) it should say yes nevertheless, as long as its on the path and executable on the users system. Example: if the user has a no-extention executable version of the file and a .cmd version of the file it should say "yes" for the no extension version on a linux system and "yes" to the .cmd version on a windows system. Since the users shell can only execute that version of the file. The purpose of this is to allow the script to be self-configuring (as much as possible). Any suggestions on how I might go about doing this?

• ZF Site in ZF Site? How do I redirect form subdirectory to another subdirecotry?

  - by AD

  The deal is that I have a ZF site for which root directory is /public. How should I go about redirecting to a subdirectory if I want to do next? I want to have another subdirectory under /public/ that would not be linked to a main website in any way except it using save ZF. Lets say I have this: /public/newsite/ which will include a complete modular ZF (just I have it for the main site). That is the root directory for the NEWSITE would be /public/newsite/public. So my question how do I modify my .htaccess rules so it would redirect any requests from /public/newsite/ to /public/newsite/public/? Thank you in advance.

• Finding data file location while using Microsoft Test Framework

  - by Nair

  I have been using NUnit and now I am switching to the Microsoft Unit Test frame work. In my test project I have a folder called TestData and I kept all my test input data files there. I want to use that files for my unit testing. In my test code, I am using Application name space and assembly name space but I can not get to the data folder directly until unless I write a code to find and replace some string to point to the data folder. I am sure someone might have run into the same problem, is the solution to change the path through program or is there a API call which will let us get to executing assembly folders? Thanks,

• Several modules in a package importing one common module

  - by morpheous

  I am writing a python package. I am using the concept of plugins - where each plugin is a specialization of a Worker class. Each plugin is written as a module (script?) and spawned in a separate process. Because of the base commonality between the plugins (e.g. all extend a base class 'Worker'), The plugin module generally looks like this: import commonfuncs def do_work(data): # do customised work for the plugin print 'child1 does work with %s' % data In C/C++, we have include guards, which prevent a header from being included more than once. Do I need something like that in Python, and if yes, how may I make sure that commonfuncs is not 'included' more than once?

• how to make this piece of code work in C++?

  - by cambr

  #include<stdio.h> void print(int *arr[], int s1, int s2) { int i, j; printf("\n"); for(i = 0; i<s1; i++) { for(j = 0; j<s2; j++) { printf("%d, ", *((arr+i)+j)); } } printf("\n"); } int main() { int a[4][4] = {{0}}; print(a,4,4); } This works in C, but not in C++. error: cannot convert `int (*)[4]' to `int**' for argument `1' to `void print(int**, int, int)' Why does it not work in C++? What change is needed to be made?

• Reading line by line from a file in C

  - by mh234

  What I am trying to do is print out the contents of a file line by line. I run the program in terminal by doing: ./test testText.txt. When I do this, random characters are printed out but not what is in the file. The text file is located in the same folder as the makefile. What's wrong? #include <stdio.h> FILE *fp; int main(int argc, char *argv[]) { char line[15]; fp = fopen(*argv, "r"); while((fgets(line, 15, fp)) != NULL) { printf(line); printf("\n"); } }

• Is it possible to evaluate a JSP only once per session, and cache it after that?

  - by Bears will eat you

  My site has a nav menu that is dynamically built as a separate JSP, and included in most pages via <jsp:include />. The contents and styling of the menu are determined by which pages the user does and doesn't have access to. The set of accessible pages is retrieved from the database when a user logs in, and not during the course of a session. So, there's really no need to re-evaluate the nav menu code every time the user requests a page. Is there an easy way to generate the markup from the JSP only once per session, and cache/reuse it during the session?

• Trigger Backgroundworker Completed event.

  - by fireBand

  Hello, I am trying to display the progress bar(marque) in a separate form (progressForm) while i do some calculation in background. I know the typical way of doing it is to include the calculation in background worker and show progressForm in main thread. This approach how ever will lead to lot of synch issues in my application hence I am showing the progressForm using progressForm.ShowDialog() inside the background worker process. But I need to trigger the Completed event with in the application to close the form. Is this possible? Thanks in advance.

• reStructured Text - Escape a headline?

  - by Rory

  I have a reStructuredText document. rST uses =====, etc. as a heading format. However I need to include some lines that have this text in it, e.g.: some of my text ===== stuff ===== some more of my text And I don't want the ==== to be interpreted as a heading, i.e. I don't want stuff to be a heading. I would rather that those equal signs are just displayed as is. Is this possible in rST?

• Is it good to use JQuery's validation plugin?

  - by kwokwai

  Hi all, I am learning JQuery, and I have checked out that JQUery has got a validation plugin. http://docs.jquery.com/Plugins/Validation#Validate_forms_like_you.27ve_never_been_validating_before.21 To use it, users have to include another script file in the Head tag in HTML. I am thinking if this will cause any code collisions to the codes in the validation plugin when more and more javascript files are included. Should I use JQuery to write myself new customed functions for checking data input from users or use the JQuery data validation plugin? Please advise.

• Help getting PHP sessions to persist after being taken off-site

  - by Rob

  Hi, we're working on a payment gateway system with PHP. We use sessions to store the shopping cart data. The system takes you off-site to the payment processor's site, and then return you to your site. On most hosts, we have no issues when we arrive back at our site and having the session data still be there. On those with an issue, turning off the PHP session referer_check has worked in the past. We don't really want to have to include the PHPSESSID as a GET variable, and hope to avoid that. What I'm looking for is what other server configurations would cause the session to be killed, and any other workarounds there might be. Thanks for your help.

• using different string files in android

  - by boreas

  I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

• Why does this JavaScript destroys my layout in Internet Explorer?

  - by Sebi

  I'm using a small CMS for a small site (http://www.ovlu.li/cms/). There I include a JavaScript on the first site to open an image in a popup: <script type="text/javascript"> function pop(file) { helpwindow = window.open(file, "Vaterland", "width=600, height=796", "directories=no", "toolbar=no", "location=no", "status=no", "menubar=no", "resizable=no"); helpwindow.focus(); return false; } </script> This works fine in FireFox, Chrome and Safari, but unfortunately, in Internet Explorer this script totally destroys the layout of the site where it is contained. Nevertheless it works. And all other sites are also working correctly. Any hints?

• Prevent double submission of forms in jQuery

  - by Adam

  I have an form that takes a little while for the server to process. I need to ensure that the user waits and does not attempt to resubmit the form by clicking the button again. I tried using the following jQuery code: <script type="text/javascript"> $(document).ready(function(){ $("form#my_form").submit(function(){ $('input').attr('disabled','disabled'); $('a').attr('disabled','disabled'); return true; }) }); </script> When I try this in Firefox everything gets disabled but the form is not submitted with any of the POST data it is supposed to include. I can't use jQuery to submit the form because I need the button to be submitted with the form as there are multiple submit buttons and I determine which was used by which one's value is included in the POST. I need the form to be submitted as it usually is and I need to disable everything right after that happens. Thanks!

• Difference between SRC and HREF

  - by Vijey

  The SRC and HREF attributes are used to include some external entities like an image, a CSS file, a html file, any other web page or a javascript file. Is there a clear differentiation between SRC and HREF? where/when to use SRC or HREF? I think they can't be used interchangeably. I'm giving below few examples where these attributes are used: To refer a CSS file: href="cssfile.css" inside the link tag To refer a js file: src="myscript.js" inside the script tag To refer an image file: src="mypic.jpg" inside an image tag To refer another webpage: href="http://www.webpage.com" inside an anchor tag

• What do I need to know before working on an IM application?

  - by John

  I'm looking into building an IM-type application using Java stack (for the server at least). I'd be interested to see any information/advice on how applications like Skype/AIM/MSN work, as well as know any technologies/APIs that might be relevant. Without giving away the idea itself, it's perhaps more akin to Google Wave than Skype, but information useful for either is very welcome. Specific points I have already thought of include: Server Vs P2P... for reasons of logging my system will require all communication to go through a central server. Is this how other IM tools work... especially when audio/video comes into the equation? Cross-communication with other systems. Are there APIs for this or do all IM providers work hard to keep their protocol secret? The nature of what I'm designing means integration could probably only be limited, but it definitely seems worthwhile from a business perspective

• Can I delete a differential backup from SQL Server 2005?

  - by BlueMonkMN

  I often like to create backups when testing the software I work on, and will sometimes create a differential backup if I want to be able to get back to multiple previous states. However, sometimes I realize that I forgot one thing I wanted to include in a differential backup, or I no longer need a previous differential backup. Sometimes I simply want to create a new scenario from the original base image and start working with a new series of differential backups. So I'd like to be able to delete some older differential backups so I don't get confused about which ones I'm using. But I can't find any way to delete just the differential backups, selectively or all at once.

• Referencing invalid memory locations with C++ Iterators

  - by themoondothshine

  I am a big fan of GCC, but recently I noticed a vague anomaly. Using __gnu_cxx::__normal_iterator (ie, the most common iterator type used in libstdc++, the C++ STL) it is possible to refer to an arbitrary memory location and even change its value without causing an exception! Is this expected behavior? If so, isn't a security loophole? Here's an example: #include <iostream> using namespace std; int main() { basic_string<char> str("Hello world!"); basic_string<char>::iterator iter = str.end(); iter += str.capacity() + 99999; *iter = 'x'; cout << "Value: " << *iter << endl; }

• I want to store a php $_SESSION variable and retrieve it on another page.

• Using a framework in a PreferencePane

  - by Jonathan

  Hi, i am currently trying to implement a "third party framework" (FeedbackReporter.Framework) into my preferencepane. Unfortunately I am getting the following error all the time when trying to launch my preference pane: 16.05.10 23:13:30 System Preferences[32645] dlopen_preflight failed with dlopen_preflight(/Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane): Library not loaded: @executable_path/../Frameworks/FeedbackReporter.framework/Versions/A/FeedbackReporter Referenced from: /Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane Reason: image not found for /Users/me/Library/PreferencePanes/myPane.prefPane As far as I read so far, this problem is probably caused because my prefPane is no actual app, but a "plugin" of "System Settings.app" and thus @executable_path resolves to a path within the bundle of this app, instead of the bundle of my prefpane. But I don't really picked up howto fix this problem. I guess it must be fairly easy since it should be a usual case that people use non-apple-frameworks in PreferencePanes. Thanks for your hints!

• Why isn't the compiler smarter in this const function overloading problem?

  - by Frank

  The following code does not compile: #include <iostream> class Foo { std::string s; public: const std::string& GetString() const { return s; } std::string* GetString() { return &s; } }; int main(int argc, char** argv){ Foo foo; const std::string& s = foo.GetString(); // error return 0; } I get the following error: const1.cc:11: error: invalid initialization of reference of type 'const std::string&' from expression of type 'std::string* It does make some sense because foo is not of type const Foo, but just Foo, so the compiler wants to use the non-const function. But still, why can't it recognize that I want to call the const GetString function, by looking at the (type of) variable I assign it to? I found this kind of surprising.

• Apache crashes after installing mysqli

  - by Marco P.

  System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

• Do I need to declare all my JQuery prototypes in a JQueryStatic definition file with typescript?

  - by Marilou

  I have the following code: ///<reference path="../typescript/jquery.d.ts" /> function addThemePrototypes() { var templateSetup = new Array(); $.fn.addTemplateSetup = function(func, prioritary) { if (prioritary) { templateSetup.unshift(func); } else { templateSetup.push(func); } }; } When I try to add the following: $('a').addTemplateSetup( Into this same file I notice there is no intellisense and typescript does not seem to know about the addTemplateSetup prototype that I just added. Is this the correct way for it to work or do I always need to add things like the definition for addTemplateSetup to an JQueryStatic definition file and then include that?
