• How to pass or display mySQL data based on subscription or billing

  - by spm

  I want to build a PHP based site where, the user can view data based on the types of data they've paid for. Allow me to use something simple for an example. Let's say historical data for basketball was not readily available but could be purchased. Simple information such as the Winner, Loser, Final score and date are all stored in a mySQL table. What would be involved so that, when the user logs in, they can only see the historical data they have paid for. My theories so far about the architecture: I imagined a mySQL table storing True or False values for all historical game data they have paid for. Based on this, a 'data chart' object enables the user to view all data within their mySQL row which has a value of 'true.' Follow ups: Assuming I am correct, what methods are popular or practical for this type of service.

• How can i test my DB speed? (Learning)

  - by acidzombie24

  I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

• JQuery Ajax returned blank data

  - by kwokwai

  Hi all, I am learning how to use JQuery to help check data availability. I have written a function in a Controller for checking data input, and the URL is like this: http://www.mywebsite.com/controllers/action/avariable but the returned data was blank. <Script language="javascript"> $(document).ready(function(){ $(document).change(function(){ var usr = $("#data\\[User\\]\\[name\\]").val(); $.post{"http://www.mywebsite.com/controllers/action/", usr, function(msg){alert(msg);} } }); }); </Script> <div id="username"> <input type=text name="data[User][name]" id="data[User][name]"> </div> Here is the code of the Action: function action($data=null){ $this->autoRender = false; $result2=$this->__avail($udata); if($result2==1) {return "OK";} else {return "NOT";} }

• How to test soft deletion event listner without setting up NHibernate Sessions

  - by isuruceanu

  I have overridden the default NHibernate DefaultDeleteEventListener according to this source: http://nhforge.org/blogs/nhibernate/archive/2008/09/06/soft-deletes.aspx so I have protected override void DeleteEntity( IEventSource session, object entity, EntityEntry entityEntry, bool isCascadeDeleteEnabled, IEntityPersister persister, ISet transientEntities) { if (entity is ISoftDeletable) { var e = (ISoftDeletable)entity; e.DateDeleted = DateTime.Now; CascadeBeforeDelete(session, persister, entity, entityEntry, transientEntities); CascadeAfterDelete(session, persister, entity, transientEntities); } else { base.DeleteEntity(session, entity, entityEntry, isCascadeDeleteEnabled, persister, transientEntities); } } How can I test only this piece of code, without configuring an NHIbernate Session?

• How to create an image from canvas data?

  - by Jakub Hampl

  In my application I am trying to save an arbitrary part of a rendered HTML canvas to an image file. In my Javascript I call ctx.getImageData(x, y, w, h) and pass the resulting object to my macruby code (though if you know a solution in objc I am also very interested). There I'm trying to create a NSBitmapImageRep object so that I can then save to an image format the user desires. This is my code so far (the function gets a WebScriptObject as it's argument): def setimagedata(d) w = d.valueForKey("width").to_i h = d.valueForKey("height").to_i data = Pointer.new(:char, d.valueForKey("data").valueForKey("length").to_i) d.valueForKey("data").valueForKey("length").to_i.times do |i| data[i] = d.valueForKey("data").webScriptValueAtIndex(i).to_i end puts "data complete" # get's called @exported_image = NSBitmapImageRep.alloc.initWithBitmapDataPlanes(data, pixelsWide: w, pixelsHigh:h, bitsPerSample: 32, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: NSCalibratedRGBColorSpace, bitmapFormat: NSAlphaNonpremultipliedBitmapFormat, bytesPerRow: 0, bitsPerPixel: 0) puts "done" # doesn't get called end The code doesn't seem to get through the initWithBitmapDataPlanes function but gives no error. My question is: what am I doing wrong? Is this approach reasonable (if not, what would be better?).

• Preprocessor directive to test if this is C or C++

  - by Collin

  I'm trying to find a standard macro which will test whether a header file is being compiled as C or as C++. The purpose of this is that the header may be included by either C or C++ code, and must behave slightly differently depending on which. Specifically: In C, I need this to be the code: extern size_t insert (const char*); In C++, I need this to be the code: extern "C" size_t insert (const char*); Additionally, is there a way to avoid putting #ifdef's around every declaration in the header?

• What is the best way to automated (integration) test with java with OpenId4Java against real OpenIdP

  - by mP

  I would like to do a bit more than manually test my openid glue code which happens to use the openid4java library. My goals would be to be able to run it within my IDE with a bunch of tests using Junit or similar. Selenium & tomcat I was thinking of using selenium and a tomcat but thats not exactly a nice approach as this is a bit heavy and not really lightweight. httpunit A solution with http-unit is incomplete because it doesnt really fit with the redirect to my openid provider, authenticate and redirect back. Perhaps i am wrong but this looks like it could get quite involved just to make sure this works. Mocks My last solution is to mock everything and assume thats its accurate and works. If google or yahoo ever change in some way, then ill have to verify manually. The approach is simple but with a major flaw.

• Need a good website URL to test against

  - by Zombies

  I need a URL to just test basic http connectivity. It needs to be consistent and: Always be up Never change drastically due to IP or user agent. (IE: 301 Location redirect/ huge difference in content... minor would be tolerable) The URL itself has a consistent content-length. (IE: it doesn't vary from by 2kb at most, ever) A few examples, yet none match all 3 criteria: One example of always up: www.google.com (yet it 301 redirects based on IP location). Another good one is http://www.google.com/webhp?hl=en. but the problem there is that based on a given holiday, the content-length can really vary.

• How to test a regex password in Python?

  - by jCuga

  Using a regex in Python, how can I verify that a user's password is: At least 8 characters Must be restricted to, though does not specifically require any of: uppercase letters: A-Z lowercase letters: a-z numbers: 0-9 any of the special characters: @#$%^&+= Note, all the letter/number/special chars are optional. I only want to verify that the password is at least 8 chars in length and is restricted to a letter/number/special char. It's up to the user to pick a stronger / weaker password if they so choose. So far what I have is: import re pattern = "^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$" password = raw_input("Enter string to test: ") result = re.findall(pattern, password) if (result): print "Valid password" else: print "Password not valid"

• ASP.Net layered communication

  - by Chris Klepeis

  Hi, We're developing a layered web application. The specs: 3 layers, data layer, business layer, ui layer. Programmed in C# Data Layer uses the entity framework Currently we plan on having the data layer return IEnumerable<T> to the business layer via linq 2 entities, and the business layer will return data to the ui layer. Since the ui layer has no knowledge of the existance of the data layer, how would it handle a result of IEnumerable passed to it from the BLL, where T is defined in the data layer? Are there any GOOD example out there on how to do this. Please note that I'm extremely new to factories / interfaces / abstraction to loosely couple layers. I saw the question here http://stackoverflow.com/questions/917457/passing-data-in-an-ntier-application and it was recommended to have the entity layer shared amongst all layers... however I do not want the other layers to be able to query the database.

• Ideal way/architecture to deliver large data over Web Services

  - by zengr

  We are trying to design 6 web services, which will serve another client component. The client component requires data from the web service we are implementing. Now, the problem is, there is not 1 WS we are implementing, there is one WS which the client component hits, this initiates a series (5 more) of WSs which gather data from their respective data stores and finally provide the data back to the original WS, which then delivers the data back to the client component. So, if the requested data becomes huge, then, this will be a serious problem for our internal communication channel. So, what do you guys suggest? What can be done to avoid overloading of the communication channel between the internal WS and at the same time, also delivering the data to the client component.

• How to prevent bad formatted data input in DataGridViewCell

  - by JuanNunez

  I have an automatically binded DataGridView that obtains data and update data directly from a Strongly Typed Dataset and its TableAdapter. the DataGridView allows data editing but I'm having issues dealing with bad formatted data input. For example, one of the columns is a date, formatted in the database as datetime, 11/05/2010. You can edit the date and the DataGridView opens a TextBox in wich you can enter letters, simbols and other unauthorised characters. When you finish editing the cell if has such bad data it throws a System.FormatException How can I prevent some data to be entered? Is there a way to "filter" that data before it is sent back to the DataGridView?

• [C++] Boost test: catch user defined exceptions

  - by user231536

  If I have user defined exceptions in my code, I can't get Boost test to consider them as failures. For example, BOOST_AUTO_TEST_CASE_EXPECTED_FAILURES(MyTest,1) BOOST_AUTO_TEST_CASE(MyTest) { // code which throws user defined exception, not derived from std::exception. } I get a generic message: Caught exception: .... unknown location(0):.... It does not recognize this error as a failure since it is not a std::exception. So it does not honor the expected_failures clause. How do I enforce that the piece of code should always throw an exception? THis seems to be a useful thing to want. In case future code changes cause the code to pass and the exception is not thrown, I want to know that.

• Speed of running a test suite in Rails

  - by Milan Novota

  I have 357 tests (534 assertions) for my app (using Shoulda). The whole test suite runs in around 80 seconds. Is this time OK? I'm just curious, since this is one of my first apps where I write tests extensively. No fancy stuff in my app. Btw.: I tried to use in memory sqlite3 database, but the results were surprisingly worse (around 83 seconds). Any clues here? I'm using Macbook with 2GB of RAM and 2GHz Intel Core Duo processor as my development machine.

• test php disabled caching

  - by user1691389

  My site had a problem in that certain browsers (especially opera and gecko) were "over-caching" (caching far too much for my taste). I've just added the following PHP snippet to hopefully disable caching in all browsers: <?php header("Expires: Tue, 01 Jan 2000 00:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); ?> Question: How would you test this out, to make sure it actually works?

• Shell scripting and test expressions

  - by Paul

  Hi, I'm trying to test whether a directory path exists when a file is passed to my script. I use dirname to strip and save the path. I want my script to run only if the path exists. This is my attempt below. FILE=$1 DIRNAME=dirname $FILE if [ -z $DIRNAME ] ; then echo "Error no file path" exit 1 fi But this doesn't work. Actual when there is no file path dirname $FILE still returns "." to DIRNAME, i.e. this directory. So how do i distinguish between "." and "/bla/bla/bla". Thanks.

• Hyperlinks in VS2008 Test Result Details

  - by Red XIII

  In case when resulting string in "Test Result Details" (TRD) is very long, the Visual Studio 2008 crashes. I fixed this by sending the result data into a file. There is a problem, however, because there isn't a simple way to open such file. Of course, I can manually open folder and then the file, but it isn't very efficient. Now, to the questions part. Is there a possibility to include in the "Error Message" part of TRD a hyperlink to a file? (something similar to what we can already find in the stack trace part) If not, is there any way to add such functionality (easy opening of a file) to TRD? If not, are there any ways to expand the default reporting of VS? Thanks for any help.

• Count The Amount Of Data In An Array Including SOME Null

  - by Josephine

  I'm coding in java and I need to create a function that returns the number of Data objects that are currently in an ArrayList. At the moment I have this: int count = 0; for (int i = 0; i < data.length; i++) { if (data[i] != null) { count ++; } } return count; But the problem is that an array list that includes null data is acceptable, and I have to count their null data towards this counter. How do I include the null data that's in the middle of this array, and not the null data that's not supposed to be counted for? For example, I have some tester code that adds (8),null,null,(23),(25) to the array, and this function should return 5 when the initial array size is 10. Thank you so much

• Java: Can't implement runnable on a test case: void run() collides

  - by Zombies

  So I have a test case that I want to make into a thread. I cannot extend Thread nor can I implement runnable since TestCase already has a method void run(). The compilation error I am getting is Error(62,17): method run() in class com.util.SeleneseTestCase cannot override method run() in class junit.framework.TestCase with different return type, was class junit.framework.TestResult. What I am trying to do is to scale a Selenium testcase up to perform stress testing. I am not able to use selenium grid/pushtotest.com/amazon cloud at this time (installation issues/install time/resource issues). So this really is more of a Java language issue for me.
