• Recommended Model Based Testing Tools

  - by ModelTester

  Does anyone have any suggestions on what Model Based Testing Tools to use? Is Spec Explorer/SPEC# worth it's weight in tester training? What I have traditionally done is create a Visio Model where I call out the states and associated variables, outputs and expected results from each state. Then in a completely disconnected way, I data drive my test scripts with those variables based on that model. But, they are not connected. I want a way to create a model, associate the variables in a business friendly way, that will then build the data parameters for the scripts. I can't be the first person to need this. Is there a tool out there that will do basically that? Short of developing it myself.

• Special characters in PHP / MySQL

  - by Jonathan

  Hi, I have in the database words that include special character (in Spanish mostly, like tildes). In the database everything is saved and shown correctly with PHPmyAdmin, but when I get the data (using PHP) and display it in a browser, I get a weird character, like a "?" with a square... I need a general fix so I don't need to escape each character every time, and also I would be able to insert special Spanish characters from a PHP form into the database... The HTML is correct: <meta http-equiv="content-type" content="text/html; charset=utf-8" /> All tables and databas are set to utf8_spanish The character I get: ? Any suggestions??? Thanks!!!

• Cross-Page communication in firefox extension

  - by OzBarry

  I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

• Tables are not visible in SQL Server Management Studio but they are in Visual Studio using same acco

  - by Germ

  I'm experiencing a weird problem with a particular SQL login. When I connect to the server in Microsoft SQL Server Management Studio (2008) using this account, I cannot see any of the tables, stored procedures etc. that this account should have access to. When I connect to the same server within Visual Studio (2008) with the same account everything is there. I've also had a co-worker connect to the server using the same login and he's able to view everything as well. The strange thing is if I switch logins, I'm able to view objects that the other account has access to which indicates that there isn't a problem with MSSMS on my PC. Does anyone have any suggestions on how I can diagnose this problem? I've check to make sure I don't have any Table filters etc.

• setting permissions of python module (python setup install)

  - by SetJmp

  I am configuring a distutils-based setup.py for a python module that is to be installed on a heterogeneous set of resources. Due to the heterogeneity, the location where the module is installed is not the same on each host however disutils picks the host-specific location. I find that the module is installed without o+rx permissions using disutils (in spite of setting umask ahead of running setup.py). One solution is to manually correct this problem, however I would like an automated means that works on heterogeneous install targets. For example, is there a way to extract the ending location of the installation from within setup.py? Any other suggestions? Thanks! SetJmp

• T-Sql SPROC - Parse C# Datatable to XML in Database (SQL Server 2005)

  - by Goober

  Scenario I've got an application written in C# that needs to dump some data every minute to a database. Because its not me that has written the spec, I have been told to store the data as XML in the SQL Server database and NOT TO USE the "bulk upload" feature. Essentially I just wanted to have a single stored procedure that would take XML (that I would produce from my datatable) and insert it into the database.....and do this every minute. Current Situation I've heard about the use of "Sp_xml_preparedocument" but I'm struggling to understand most of the examples that I've seen (My XML is far narrower than my C Sharp ability). Question I would really appreciate someone either pointing me in the direction of a worthwhile tutorial or helping explain things. EDIT - Using (SQL Server 2005)

• What's the best way to authorize a USB Key

  - by ScottCate

  We have an auto update for our software that is installed via USB key (with the auto run). If I wanted to ensure that only authorized USB Keys were used, what's the best way? Our installer is already signed, and it won't run otherwise. But I'm more wanting to inspect the USB Key for a signed installer, and if it's not there, just ignore, or even "Eject" the USB device. And I should be able to tell the difference (in code) between a usb storage device, and say a camera, or keyboard. I'm only wanting to disable non-authorized storage devices. Thank you for your ideas.

• Why is IHttpAsyncHandler being called over IHttpHandler?

  - by Tim Hardy

  I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest(). Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController. I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.

• How to reduce simple cpp application size? (compiled with RAD Studio 2010 cpp builder)

  - by peterg

  I am using rad studio 2010 cpp builder. I've created a new SDI application, added a TCppWebBrowser control and a simple button that onclick trigger the .navigate for the TCppWebBrowser, I compiled it and I got a 1.20mb file, I was expecting less than 700kb at least. How can I reduce the size of the compiled exe? I don't want to use "build with runtime packages", I know that will make it very small but I want to get all the necessary packages and dependencies inside the exe but maybe I am getting more than I use, I tried unchecking/removing a lot of design packages (in project/options/packages) I don't use but the file size didn't decreased. Also I was thinking maybe the TForm component that comes with RAD Studio is giving me more stuff than I need and that could make the file bigger, I mean I only need to drop a webbrowser control and a few buttons in the form, maybe there's a minimal form component I could use to replace TForm. Any suggestions will be appreciated.

• Native Mouse events with Flash and Selenium

  - by Dan at Demand

  I understand that Selenium does not support Flash, but it is my understanding that I should be able to do some simplistic testing of Flash by using Selenium's built in native mouse support and doing mouse up/down events based on coordinates. Is this correct? I can't seem to get it working. I'm trying to test on this page: http://mandy-mania.blogspot.com/2010/04/sneak-peek-of-final-season-of-lost-dvd.html and all I'm trying to do is click on the flash object so it plays the video. I've tried all sorts of commands, MouseOver, MouseDown, MouseDownAt, MouseUp, MouseUpAt, etc. So, I'm wondering if this just theoretically doesn't work or if I'm just doing something wrong. The xpath I'm using is //object[@id='player'], although I've tried a number of different combinations. And yes, I've also tried just the straight click command. Any suggestions? Thanks!

And my customers will be on my website longer.. Any suggestions??

• Fancy Box doesnt work please help

  - by JL

  I recently came across fancy box located here, I've followed every step in the instructions perfectly, but it doesn't work, anyone know what might be the problem? Here is a sample of my page source: Included the links to scripts as required, and CSS: <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox-1.2.1.js" type="text/javascript"></script> <link href="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox.css" rel="stylesheet" type="text/css" /> <link href="css/main.css" rel="stylesheet" type="text/css" /> Then this should simply work: <a id="single_image" href="images/279641.jpg"><img src="images/279641.jpg" /></a> But it doesn't seem to do anything except open the image in a new window. Any suggestions, and thanks in advance.

• Dashcode and firefox compatibility

  - by nacho4d

  Hi all, I started to use Dashcode with a Safari Custom Project, my apps work fine, but StackLayout Object does not work in Firefox. I know Dashcode use many wekbit-specific things but is there any way I can get StackLayout object o work in Firefox? I would not mind losing some fancy stuff like transition-animations as long as my Views change. StackLayout also does not work in IE, but I think that is too much to expect from IE. lol. Any suggestions, ideas? Maybe jQuery or Dojo libraries can be used with DashCode in case webkit is not available?. in this case how can I do this? Thanks.

• What's the cause of (and treatment for) this java MySQL exception?

  - by justkevin

  I'm getting the following exception when executing the first preparedstatement after a period of inactivity: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 2,855,054 milliseconds ago. The last packet sent successfully to the server was 123 milliseconds ago. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.mysql.jdbc.Util.handleNewInstance(Util.java:406) at com.mysql.jdbc.SQLError.createCommunicationsException(SQLError.java:1074) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:3052) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2938) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3481) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1959) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2109) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2648) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:2077) at com.mysql.jdbc.PreparedStatement.executeQuery(PreparedStatement.java:2228) This only shows up if my application hasn't communicated with MySQL recently. Subsequent queries execute normally. I suspect it's some kind of timeout issue, but the periods of inactivity are way below the 8 hour timeout for MySQL. Any suggestions?

• How do I close a database connection being used to produce a streaming result in a WCF service?

  - by Dan

  I have been unable to find any documentation on properly closing database connections in WCF service operations. I have a service that returns a streamed response through the following method. public virtual Message GetData() { string sqlString = BuildSqlString(); SqlConnection conn = Utils.GetConnection(); SqlCommand cmd = new SqlCommand(sqlString, conn); XmlReader xr = cmd.ExecuteXmlReader(); Message msg = Message.CreateMessage( OperationContext.Current.IncomingMessageVersion, GetResponseAction(), xr); return msg; } I cannot close the connection within the method or the streaming of the response message will be terminated. Since control returns to the WCF system after the completion of that method, I don't know how I can close that connection afterwards. Any suggestions or pointers to additional documentation would be appreciated.

• Generate PDF - how to create paged HTML content beforehand?

  - by Alt_Doru

  My task is to create ready-to-print invoices from a .NET web app. I am already generating the printer-friendly HTML for an invoice - it consists of an invoice header (that will actually need to appear on each printed page) and invoice positions (that may span multiple printed pages). Now, my task is to generate a PDF server-side, populate a header on each of its pages, then populate its pages with invoice positions. I need to generate the PDF from the existing HTML data - by simply passing HTML input to the PDF generator library. I've started using ABCPDF - I am using the AddImageHtml method. The problem I have is that ABCPDF seems to expect me to supply HTML content already paged. So, it won't work correctly when I feed it HTML content that would span on more than 1 PDF page. So, my question is - do you have any suggestions on making this work with ABCPDF? Or, more generally speaking, what other tools/approaches would you use for this - generating PDF doc with headers/footers from HTML input? Thanks

• How to add a timeout value when using Java's Runtime.exec()?

  - by James Adams

  I have a method I am using to execute a command on the local host. I'd like to add a timeout parameter to the method so that if the command being called doesn't finish in a reasonable amount of time the method will return with an error code. Here's what it looks like so far, without the ability to timeout: public static int executeCommandLine(final String commandLine, final boolean printOutput, final boolean printError) throws IOException, InterruptedException { Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(commandLine); if (printOutput) { BufferedReader outputReader = new BufferedReader(new InputStreamReader(process.getInputStream())); System.out.println("Output: " + outputReader.readLine()); } if (printError) { BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream())); System.out.println("Error: " + errorReader.readLine()); } return process.waitFor(); } Can anyone suggest a good way for me to implement a timeout parameter? Thanks in advance for any suggestions! --James

• What is the best way to manage one's session variables?

  - by donde

  In my .NET web app, I keep basic user info in a user session object. I also usually keep a director class in the session; which is basically just has info about whatever thing it being worked on on that screen (like a customer id). I am trying to keep from adding a ton of sessions. I also want to make sure at any given time ONLY the sessions that are necessary are in memory. This means I need an effective way of managing my session variables. Any suggestions?

• ASP.NET MVC 2.0 Client-Side Validation HOWTO

  - by AlexWalker

  Where can I find some good information on the new client-side validation functionality included in ASP.NET MVC v2? I'd like to find information about using the client-side validation JavaScript without using DataAnnotations, and I'd like to find out how custom validations are handled. For example, if I want to validate two fields together, how would I utilize the provided JavaScript? Or if I wanted to write validation code on the server-side that queried a database, how could I use the provided JavaScript to implement a similar validation? I don't see any books on MVC2 yet, and the blog entries I've found are not detailed enough.

• How to differentiate new items from existing items in SharePoint workflow

  - by Jim Hoerber

  I have a SPD workflow that is set to run when an item changes but it keeps getting triggered on new items, which is pretty annoying. I'm looking into why this is happening but I'm also looking for a way to terminate the workflow if the item is new as a temporary workaround. I tried to compare the Created field to the Modified field i.e. if Created and Modified are the same then don't run. This didn't work, either as a date or string comparison. Any suggestions would be much appreciated.

• Developer workload management software: recommendations?

  - by PaddyC

  In my place, we use two issue tracking tools, one for production bugs, and another for issues on projects in development. These tools are good for managers. However, at an individual level, other work can also arrive through desk visits, email, or the phone, and those allocating the work aren't always interested in issue tracking systems. I've recently rolled off an 18-month project where I got into a cycle of overtime, and I found that I didn't always have good visibility of all work assigned to me. As a result, I was always very busy, and felt constantly laden down with work, but didn't have the clear data to show my manager (or, ironically, the time to stop and gather the information!). A handwritten list, updated at the end of each day, is a good start, but can anyone recommend better tools to help me get a clear view of my own workload? Ideally, I'm thinking of software tools for developers, which could incorporate estimates, but all suggestions welcome. Thanks, Paddy

• Need an ASP.NET MVC long running process with user feedback

  - by Jason

  I've been trying to create a controller in my project for delivering what could turn out to be quite complex reports. As a result they can take a relatively long time and a progress bar would certainly help users to know that things are progressing. The report will be kicked off via an AJAX request, with the idea being that periodic JSON requests will get the status and update the progress bar. I've been experimenting with the AsyncController as that seems to be a nice way of running long processes without tying up resources, but it doesn't appear to give me any way of checking on the progress (and seems to block further JSON requests and I haven't discovered why yet). After that I've tried resorting to storing progress in a static variable on the controller and reading the status from that - but to be honest that all seems a bit hacky! All suggestions gratefully accepted!

• A problem about in_array

  - by SpawnCxy

  Hi all, I have got a strange problem about in_array recently which I cannot understand. e.g. $a = array('a','b','c'); $b = array(1,2,3); if (in_array(0,$a)) { echo "a bingo!\n"; } else { echo "a miss!\n"; } if (in_array(0,$b)) { echo "b bingo!\n"; } else { echo "b miss!\n"; } I ran it on my lamp,and got a bingo! b miss! I read the manual and set the third parament $strict as true,then it worked as expected.But does that mean I always need to set the strict parament as true when using in_array?Suggestions would be appreciated. Regards
