• Visual Studio 2008 SignTool.exe not found

  - by Maslow

  I can't publish in 2008, I was previously using 2005 and it published just fine. Error 2 An error occurred while signing: SignTool.exe not found. I know there are tons of hits for a search on signtool.exe on google. The ones I've found involve copying the file to X,Y,Z locations and ensuring signtool matches up with your VS command prompt path. When I run my start- program files - visual studio 2008 - Visual Studio Tools - Visual Studio Command prompt. and type signtool.exe it finds the file just fine. I have Visual Studio 2005 professional edition, Visual studio 2008 profession edition, Visual studio 2005 SDK February 2007, just installed Visial Studio 2008 SDK1.1 to see if that would fix it, no luck. I have copied signtool.exe to lots of places that were suggested on the google searches, it is now located at all of the following: C:\Program Files\Visual Studio 2005 SDK\2007.02 C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools C:\Program Files\Microsoft Visual Studio 9.0\VB\Bin C:\WINNT\Microsoft.NET\Framework\v3.5 C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\Bin C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin C:\Program Files\Microsoft Visual Studio 9.0\SDK\v3.5\Bin C:\Program Files\Microsoft Visual Studio 9.0\VB\Bin\1033 C:\Program Files\Visual Studio 2005 SDK\2007.02\VisualStudioIntegration\Tools\Bin I'm on windows XP 2009-06-12 update I can only publish if I copy signtool.exe to the project folder I'm publishing now.

• ejb testing issues with netbeans and openejb

  - by SibzTer

  I have created a netbeans 6.7 EnterpriseApplication project with ejb and war modules with a test stateless session ejb with a simple sayHello() method. I also added the openEjb library in order to unit test the ejb.

• How to obtain dependency metrics from Java source code?

  - by Bram Schoenmakers

  For an assignment we have to extract some software metrics from the Hibernate project. We have to extract the afferent coupling and efferent coupling metrics (dependency fan-in, fan-out) from each revision of each package in Hibernate. Some tools were provided which are able to extract these metrics, such as ckjm and JDepend. Other tools I have checked were Sonar, javancss and AOP. There is also the Metrics Eclipse plugin which I didn't get to work either. What these tools have in common, as far as I can see, is that they all operate on bytecode (*.class files). This is a problem, because I have to build every revision from source in order to run, say, JDepend on it. Older revisions won't build because my development stack is too recent. What I would like to do is to do this kind of analysis on source files so that I don't have to build each revision. Is this possible? Or is there a good reason why all these tools only operate on bytecode?

• Windows system monitoring and profiling

  - by Aris

  I have several dozen 64-bit Windows 2003 servers in a high performance environment with very bursty system utilization. I am looking for a tool (or tools) to monitor and analyze system performance (eg, CPU utilization, bandwidth, etc). This tool can either query servers from a central location (SNMP) or require installation of a component on each server. It should poll on a 1-second interval. It should be able to generate pretty graphs which show trends over time. As a nice-to-have, it should be able to send out emails or IMs when certain thresholds are exceeded. The tools I have investigated so far, including Solarwinds and PRTG, are not designed to poll this frequently. They seem to be designed for a ~30-second interval. Solarwinds wouldn't go lower than 3-sec, and PRTG chokes at 1-sec. They both default to 1-min. All three tools seem more focused on outage monitoring and reporting than metric collection. Given the bursty nature of our applications, such infrequent polling would result in a very inaccurate picture of performance. I am considering rolling my own solution using perfmon. This would be a lot of work, and seems like reinventing the wheel. Are there any tools out there that meet my needs?

• Android fragments problems different layouts

  - by juan

  I have two layouts: one for portait with one container and another for landscape with two containers. In the first layout I show a fragment and when the user select one element, I replace the fragment with another (with FragmentTransation.Replace). <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:id="@+id/container1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" /> </RelativeLayout> In the second layout I want to show the two fragments at one time, one in the first container and the second in the second container. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:id="@+id/container1" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="3" android:orientation="vertical" /> <LinearLayout android:id="@+id/container2" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="7" android:orientation="vertical" /> </LinearLayout> But I can't make this works with configuration changes. I try use different names for containers, try add fragments when only bundle is null,... Someone have a working code of this case?

• Coherent access to mainframe files from Win32 application and IBM RDZ/Eclipse?

  - by Ira Baxter

  I have a suite of tools for processing IBM COBOL source code; these tools are built as Win32 applications and talk to Windows (including network) files using traditional Windows file system calls (open, close, read, write) and work just fine, thank you. I'd like to integrate these with Eclipse; we understand how to get Eclipse to do UI for us we think. The problem is that Eclipse/RDZ users access mainframe files through some IBM magic. In How does RDZ access mainframe files I tried to understand how Eclipse accessed files on a mainframe. Apparantly Eclipse/RDZ has a secret filesystem access backdoor not available to normal mortals. At issue is how our tools, reading some Windows-accessible file (local disk file, NFS to mainframe, ...) can associate such files with the files that Eclipse can access or is using? Ideally we'd like UI-integrated versions of our tools take an Eclipse file-name string for a mainframe file, pass it to our Windows application to process, have the Windows application open/read/process the file, and return results associated with that file to the Eclipse UI. Is there a canonical file name path that would be used with mainframe NFS that would be equivalent to the name or access object the Eclipse RDZ used to access the same file? Are all operations doable internally by Eclipse, doable by the mainframe NFS [for instance, can NFS read/update an element in a partitioned data set? Can Eclipse RDZ? Does it matter?] Is the mainframe file access available to custom Java code running under Eclipse RDZ (e.g., equivalents of open/close/read/write based on filename/path/something?) If so, can somebody steer me towards documentation describing the access methods? Anybody else already solve this problem or have a good suggestion?

• rails server fails to start with mysql2 using rvm & ruby 1.9.2-p0 on OSX 10.6.5

• Ideas for a rudimentary software licensing implementation

  - by Ross

  I'm trying to decide how to implement a very basic licensing solution for some software I wrote. The software will run on my (hypothetical) clients' machines, with the idea being that the software will immediately quit (with a friendly message) if the client is running it on greater-than-n machines (n being the number of licenses they have purchased). Additionally, the clients are non-tech-savvy to the point where "basic" is good enough. Here is my current design, but given that I have little to no experience in the topic, I wanted to ask SO before I started any development on it: A remote server hosts a MySQL database with a table containing two columns: client-key and license quantity The client-side application connects to the MySQL database on startup, offering it's client-key that I've put into a properties file packaged into the distribution (I would create a new distribution for each new client) Chances are, I'll need a second table to store validation history, so that with some short logic, the software can decide if it can be run on a given machine (maybe a sliding window of n machines using the software per 24 hours) If the software cannot establish a connection to the MySQL database, or decides that it's over the n allowed machines per day, it closes The connection info for the remote server hosting the MySQL database should be hard-coded into the app? (That sounds like a bad idea, but otherwise they could point it to some other always-validates-to-success server) I think that about covers my initial design. The intent being that while it certainly isn't full-proof, I think I've made it at least somewhat difficult to create an easily-sharable cracking solution. Also, I can easily adjust the license amount for a given client/key pair. I gotta figure this has been done a million times before, so tell me about a better solution that's just as simple to implement and provides the same (low) amount of security. In the event that external libraries are used, I prefer Java, as that's what the software has been written in.

• google maps api v2 - dynamic load (tens of thousands of) markers

  - by Adam

  Hello, how made with JavaScript+PHP+MYSQL and Google Maps API v2 dynamic load of markers? atm I have map follow example http://googlemapsapi.martinpearman.co.uk/infusions/google_maps_api/basic_page.php?map_id=8 but my marker_data_01.php (where are all markers listed - look code of example) have atm 4MB and will only have more, and more. So the question is: how load only this markers to marker_data_01.php (of some other modification of it, can be on same file as map, meaningless, I load it all from MySQL atm) what I look now: so for example (I dont know what number will good but I write this only for show what I wanna made OR JUST something like it), so top left corner for example have position: 10, top right corner for example have position: 30, bottom left corner for example have position: 5, bottom right corner for example have position: 15. -- so load only this markers what are in this box 10-30-5-15 with for example GET, and when I move map for example to 17-12-48-20 box then made next GET request and with this mysql quote and download next markers that what I see now, with this I can have map with unlimited markers, and when will be a lot of markers then clustering can link them, so with this ppl dont will need do "preload" of all markers DB (what have 4mb now and will have more), but only download that what they see at the moment, I know that is possible because a lot sites have it but I am not master of code langs, I know only a bit php and mysql (and html) :) // sorry for my english

• Ruby script/console and Ruby script/server using two different DBs?

  - by aronchick

  Has anyone seen where script/console and script/server load two different databases (though both report using the same)? Here's the first output $ script/server => Booting WEBrick => Rails 2.3.5 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2010-03-21 15:54:05] INFO WEBrick 1.3.1 [2010-03-21 15:54:05] INFO ruby 1.8.7 (2010-01-10) [i386-mingw32] [2010-03-21 15:54:05] INFO WEBrick::HTTPServer#start: pid=7148 port=3000 No errors. I then run my standard code for entering a form - no problems. Checking the Dev Database (.yml at bottom): mysql> select * from books; [...] | 712 | Book | Book Name | 2010-03-21 22:29:22 | 2010-03-21 22:29:22 | [...] 712 rows in set (0.00 sec) The code CLEARLY saved it seconds ago And now here's the output of script/console: $ script/console Loading development environment (Rails 2.3.5) >> Books.all => [] Nothing. Further, upon further inspection, it's using the production database, but I can't figure out why. Any thoughts here? All consoles have been closed and reopened.

• Where should you put 3rd party .NET dlls when using git submodules to avoid duplication

  - by Tim Abell

  I have two .NET library projects in Visual Studio 2008 that both make use of the MySql Connector for .NET (MySql.Data.dll). These libraries are then in turn both used by a .NET command line application which also uses the Connector. The library projects are pulled in to the application's solution as git submodules and referenced by project in Visual Studio. I'm looking for the most effective strategy for storing and referencing the MySql Connector library. I have tried having the MySql.Data.dll checked in to all three projects (in their root folder), this was problematic when one project changed to a newer version of the connector dll. Although each project had its own version of the dll, only one was packaged into the resultant application leading to an API mismatch which was hard to pin down. This has put me off this approach. I have tried having the command line application reference the connector dll that is held in a submodule, however this only removes the possibility of version mismatches when there is only one submodule rather than two as in this case. I am contemplating putting the dll in the global assembly cache (GAC) of all machines that need to build or use the application, but I'm wary of not having all dependencies for an application available in source control.

• Hibernate JDBCConnectionException: Communications link failure and java.io.EOFException: Can not read response from server

  - by Marc

  I get a quite well-known using MySql jdbc driver : JDBCConnectionException: Communications link failure, java.io.EOFException: Can not read response from server. This is caused by the wait_timeout parameter in my.cnf. So I decided to use c3p0 pool connection along with Hibernate. Here is what I added to hibernate.cfg.xml : <property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> <property name="c3p0.min_size">10</property> <property name="c3p0.max_size">100</property> <property name="c3p0.timeout">1000</property> <property name="c3p0.preferredTestQuery">SELECT 1</property> <property name="c3p0.acquire_increment">1</property> <property name="c3p0.idle_test_period">2</property> <property name="c3p0.max_statements">50</property> idle_test_period is volontarily low for test purposes. Looking at the mysql logs I can see the "SELECT 1" request which is regularly sent to the mysql server so it works. Unfortunately I still get this EOF exception within my app if I wait longer than 'wait_timout' seconds (set to 10 for test purposes). I'm using Hibernate 4.1.1 and mysql-jdbc-connector 5.1.18. So what am I doing wrong? Thanks, Marc.

• CakePHP: Missing database table

  - by Justin

  I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

• Best XML format for log events in terms of tool support for data mining and visualization?

  - by Thorbjørn Ravn Andersen

  We want to be able to create log files from our Java application which is suited for later processing by tools to help investigate bugs and gather performance statistics. Currently we use the traditional "log stuff which may or may not be flattened into text form and appended to a log file", but this works the best for small amounts of information read by a human. After careful consideration the best bet has been to store the log events as XML snippets in text files (which is then treated like any other log file), and then download them to the machine with the appropriate tool for post processing. I'd like to use as widely supported an XML format as possible, and right now I am in the "research-then-make-decision" phase. I'd appreciate any help both in terms of XML format and tools and I'd be happy to write glue code to get what I need. What I've found so far: log4j XML format: Supported by chainsaw and Vigilog. Lilith XML format: Supported by Lilith Uninvestigated tools: Microsoft Log Parser: Apparently supports XML. OS X log viewer: plus there is a lot of tools on http://www.loganalysis.org/sections/parsing/generic-log-parsers/ Any suggestions?

• SQL: select rows with the same order as IN clause

  - by Andrea3000

  I know that this question has been asked several times and I've read all the answer but none of them seem to completely solve my problem. I'm switching from a mySQL database to a MS Access database with MS SQL. In both of the case I use a php script to connect to the database and perform SQL queries. I need to find a suitable replacement for a query I used to perform on mySQL. I want to: perform a first query and order records alphabetically based on one of the columns construct a list of IDs which reflects the previous alphabetical order perform a second query with the IN clause applied with the IDs' list and ordered by this list. In mySQL I used to perform the last query this way: SELECT name FROM users WHERE id IN ($name_ids) ORDER BY FIND_IN_SET(id,'$name_ids') Since FIND_IN_SET is available only in mySQL and CHARINDEX and PATINDEX are not available from my php script, how can I achieve this? I know that I could write something like: SELECT name FROM users WHERE id IN ($name_ids) ORDER BY CASE id WHEN ... THEN 1 WHEN ... THEN 2 WHEN ... THEN 3 WHEN ... THEN 4 END but you have to consider that: IDs' list has variable length and elements because it depends on the first query that list can easily contains thousands of elements Have you got any hint on this? Is there a way to programmatically construct the ORDER BY CASE ... WHEN ... statement? Is there a better approach since my list of IDs can be big?

• Why is Firefox so bloated? [closed]

  - by bvandrunen

  First off I am a developer who loves firebug and other development tools (and no Chrome firebug lite does not cut it) and am just utterly frustrated when I have been using Firefox lately. It is at the point where I use Chrome for absolutely everything but web development but am still frustrated that I had to switch where half a year ago or more Firefox was fine. Why can't there be a Firefox lite? One that is free from all the bloat that has been plaguing Firefox recently. Also if there are any tools or tips that I can free up my Firefox that would be great. I am using the newest version + as few add-ons as possible. EDIT: I have tried Chrome Developer Tools and I do like them...but I can't get passed the firebug lite extension of Chrome. Some of the developer tools are great but sometimes they just have too much information. I extensively use Firebug/myphp admin. Both of these work much much better in Firefox then Chrome. But I hate that it takes me so much longer to load and use everything.

• How do I code and compile an Amiga application?

  - by nbolton

  I would like to program an application for the Amiga, just for fun! Please could someone post a step by step howto based on the following? Exactly what programming tools I should use, are there any already installed? Am I limited to plain text editors, or are there IDEs and debugging tools available? If no tools are already installed, how can this done? Are there free ones? I'd like to learn a traditional Amiga language, could you reccomend one? What should I use to compile the language you suggest? Please could you suggest tools I may use to debug the suggested language? Are there any libraries I should be aware of, such as GUI libraries? Some things to note... I'm running Workbench 3.1 from within the WinUAE emulator. From Workbench, I can access files from my Windows hard drive. I'd like to code and compile it from Workbench if possible. I'm running WinUAE in A1200 mode, not sure if that matters. There's an application already installed called MEmacs. I know C++ and C# very well, maybe there's a similar Amiga language. I'm aware that you can code with C and C++, but I want to learn a new language. Update: I have answered my own question, but please do contribute more answers as I intend on extending my answer. Thanks to all that have contributed so far, you've been very helpful!

• using 'or' operator not working for menu

  - by John Wilkes

  In my code here, I have a CSS class called "active" which I use if the $_GET['page'] == tutorials, php, mysql, etc... The problem is, even if the 'page' variable is not equal to any of these values, the Tutorials button in this case is still active for some reason. Any ideas why this would be happening? Am I using the 'or' (||) operand incorrectly? <?php if($_GET['page'] == 'tutorials' || 'php' || 'mysql' || 'html' || 'css' || 'js') { ?> <li class="active"> <?php } else { ?> <li> <?php } ?> <a href="index.php?page=tutorials">Tutorials</a> <ul> <li><a href="index.php?page=php">PHP</a></li> <li><a href="index.php?page=mysql">MySQL</a></li> <li><a href="index.php?page=html">HTML</a></li> <li><a href="index.php?page=css">CSS</a></li> <li><a href="index.php?page=js">JS</a></li> </ul> </li>

• starting rails in test environment

  - by Brian D.

  I'm trying to load up rails in the test environment using a ruby script. I've tried googling a bit and found this recommendation: require "../../config/environment" ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test' This seems to load up my environment alright, but my development database is still being used. Am I doing something wrong? Here is my database.yml file... however I don't think it is the issue development: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_development pool: 5 username: root password: dev host: localhost # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_test pool: 5 username: root password: dev host: localhost production: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_production pool: 5 username: root password: dev host: localhost I can't use ruby script/server -e test because I'm trying to run ruby code after I load rails. More specifically what I'm trying to do is: run a .sql database script, load up rails and then run automated tests. Everything seems to be working fine, but for whatever reason rails seems to be loading in the development environment instead of the test environment. Here is a shortened version of the code I am trying to run: system "execute mysql script here" require "../../config/environment" ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test' describe Blog do it "should be initialized successfully" do blog = Blog.new end end I don't need to start a server, I just need to load my rails code base (models, controllers, etc..) so I can run tests against my code. Thanks for any help.

• Database choices

  - by flobadob

  I have a prickly design issue regarding the choice of database technologies to use for a group of new applications. The final suite of applications would have the following database requirements... Central databases (more than one database) using mysql (myst be mysql due to justhost.com). An application to be written which accesses the multiple mysql databases on the web host. This application will also write to local serverless database (sqlite/firebird/vistadb/whatever). Different flavors of this application will be created for windows (.NET), windows mobile, android if possible, iphone if possible. So, the design task is to minimise the quantity of code to achieve this. This is going to be tricky since the languages used are already c# / java (android) and objc (iphone). Not too worried about that, but can the work required to implement the various database access layers be minimised? The serverless database will hold similar data to the mysql server, so some kind of inheritance in the DAL would be useful. Looking at hibernate/nhibernate and there is linq to whatever. So many choices!

• Javascript function with PHP throwing a "Illegally Formed XML Syntax" error

  - by Joe

  I'm trying to learn some javascript and i'm having trouble figuring out why my code is incorrect (i'm sure i'm doing something wrong lol), but anyways I am trying to create a login page so that when the form is submitted javascript will call a function that checks if the login is in a mysql database and then checks the validity of the password for the user if they exist. however I am getting an error (Illegally Formed XML Syntax) i cannot resolve. I'm really confused, mostly because netbeans is saying it is a xml syntax error and i'm not using xml. here is the code in question: function validateLogin(login){ login.addEventListener("input", function() { $value = login.value; if (<?php //connect to mysql mysql_connect(host, user, pass) or die(mysql_error()); echo("<script type='text/javascript'>"); echo("alert('MYSQL Connected.');"); echo("</script>"); //select db mysql_select_db() or die(mysql_error()); echo("<script type='text/javascript'>"); echo("alert('MYSQL Database Selected.');"); echo("</script>"); //query $result = mysql_query("SELECT * FROM logins") or die(mysql_error()); //check results against given login while($row = mysql_fetch_array($result)){ if($row[login] == $value){ echo("true"); exit(0); } } echo("false"); exit(0); ?>) { login.setCustomValidity("Invalid Login. Please Click 'Register' Below.") } else { login.setCustomValidity("") } }); } the code is in an external js file and the error throws on the last line. Also from reading i understand best practices is to not mix js and php so how would i got about separating them but maintaining the functionality i need? thanks!

• Drupal 7 configuration error with Postgresql in Mac OS 10.6.5

  - by Sam

  I am trying to configure Drupal 7 with Postgres. At the database setup step, I get the following error. Warning: PDO::_construct(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) in DatabaseConnection-_construct() (line 300 of /Users/shamod/Sites/drupal/7/includes/database/database.inc). In order for Drupal to work, and to continue with the installation process, you must resolve all issues reported below. For more help with configuring your database server, see the installation handbook. If you are unsure what any of this means you should probably contact your hosting provider. Failed to connect to your database server. The server reports the following message: SQLSTATE[HY000] [2002] No such file or directory. Is the database server running? Does the database exist, and have you entered the correct database name? Have you entered the correct username and password? Have you entered the correct database hostname? NOTE: I am trying to connect to Postgresql but it fails on var/mysql/mysql.sock error. I have setup the database connection string in settings.php for Postgresql. It still does not work. Any idea?

• Who needs singletons?

  - by sexyprout

  Imagine you access your MySQL database via PDO. You got some functions, and in these functions, you need to access the database. The first thing I thought of is global, like: $db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'root', 'pwd'); function some_function() { global $db; $db->query('...'); } But it's considered as a bad practice. So, after a little search, I ended up with the Singleton pattern, which "applies to situations in which there needs to be a single instance of a class." According to the example of the manual, we should do this: class Database { private static $instance, $db; private function __construct(){} static function singleton() { if(!isset(self::$instance)) self::$instance = new __CLASS__; return self:$instance; } function get() { if(!isset(self::$db)) self::$db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'user', 'pwd') return self::$db; } } function some_function() { $db = Database::singleton(); $db->get()->query('...'); } some_function(); But I just can't understand why you need that big class when you can do it merely with: class Database { private static $db; private function __construct(){} static function get() { if(!isset(self::$rand)) self::$db = new PDO('mysql:host=127.0.0.1;dbname=toto', 'user', 'pwd'); return self::$db; } } function some_function() { Database::get()->query('...'); } some_function(); This last one works perfectly and I don't need to worry about $db anymore. But maybe I'm forgetting something. So, who's wrong, who's right?
