• xsl:value-of Not Working

  - by Ashar Syed

  Hi, I am having a little issue this piece of code in my Xsl. <xsl:if test="ShippingName != ''"> <tr> <td colspan="6" style="border:none;" align="right"> <strong>Shipping Via</strong> </td> <td align="right"> <xsl:value-of select="ShippingName" /> </td> </tr> </xsl:if> It passes the test condition (ShippingName != '') and assigns the style to 'td' but at the point where I am displaying the value that this element contains (), it displays nothing. Any ideas why this could be happening. Thanks.

• mocking static method call to c# library class

  - by Joe

  This seems like an easy enough issue but I can't seem to find the keywords to effect my searches. I'm trying to unit test by mocking out all objects within this method call. I am able to do so to all of my own creations except for this one: public void MyFunc(MyVarClass myVar) { Image picture; ... picture = Image.FromStream(new MemoryStream(myVar.ImageStream)); ... } FromStream is a static call from the Image class (part of c#). So how can I refactor my code to mock this out because I really don't want to provide a image stream to the unit test.

• Testing methods called on yielded object

  - by Todd R

  I have the following controller test case: def test_showplain Cleaner.expect(:parse).with(@somecontent) Cleaner.any_instance.stubs(:plainversion).returns(@returnvalue) post :showplain, {:content => @somecontent} end This works fine, except that I want the "stubs(:plainversion)" to be an "expects(:plainversion)". Here's the controller code: def showplain Cleaner.parse(params[:content]) do | cleaner | @output = cleaner.plainversion end end And the Cleaner is simply: class Cleaner ### other code and methods ### def self.parse(@content) cleaner = Cleaner.new(@content) yield cleaner cleaner.close end def plainversion ### operate on @content and return ### end end Again, I can't figure out how to reliably test the "cleaner" that is made available from the "parse" method. Any suggestions?

• objective-c releasing uninitialized class members in dealloc method

  - by Dude Man

  Regarding over-releasing. Say I have a instance variable defined in Test.h NSString *mystring; In my implementation Test.m I do not initialize the variable mystring anywhere. But I release it in dealloc: -(void)dealloc { [mystring release]; } Is this now over-released? I've been doing the following in dealloc to avoid any issues, however, is this really necessary? -(void)dealloc { if (mystring) [mystring release]; } It seems that [nil release] shouldn't do anything, can someone verify this with class members?

• In FLEX, How can you stop ENTER Key from my Alert being caught by the control that initiated the Al

  - by WeeJavaDude

  I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this? public function init():void { myTextInput.addEventListener(KeyboardEvent.KEY_UP, handleKeyStrokes); } public function handleKeyStrokes(evt:KeyboardEvent):void { if(evt.keyCode == Keyboard.ENTER) { myAlert = Alert.show("This is a test and only a test", "Title", 4, null, alertCallBack); } } <mx:TextInput id="myTextInput" left="600" top="10"> </mx:TextInput>

• How to create a database deadlock using jdbc and JUNIT

  - by Isawpalmetto

  I am trying to create a database deadlock and I am using JUnit. I have two concurrent tests running which are both updating the same row in a table over and over again in a loop. My idea is that you update say row A in Table A and then row B in Table B over and over again in one test. Then at the same time you update row B table B and then row A Table A over and over again. From my understanding this should eventually result in a deadlock. Here is the code For the first test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Egypt"; int bpl = 0; stmt = c.createStatement(); rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); //ex.getMessage(); } } And here is the code for the second test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Jordan"; int bpl = 0; stmt = c.createStatement(); //stmt.close(); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); } } I am running these two separate JUnit tests at the same time and am connecting to an apache Derby database that I am running in network mode within Eclipse. Can anyone help me figure out why a deadlock is not occurring? Perhaps I am using JUnit wrong.

• I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS?

  - by user2567

  I try to understand the benefits of distributed version control system (DVCS). I found Subversion Re-education and this article by Martin Fowler very useful. Mercurial and others DVCS promote a new way of working on code with changesets and local commits. It prevents from merging hell and other collaboration issues We are not affected by this as I practice continuous integration and working alone in a private branch is not an option, unless we are experimenting. We use a branch for every major version, in which we fix bugs merged from the trunk. Mercurial allows you to have lieutenants I understand this can be useful for very large projects like Linux, but I don't see the value in small and highly collaborative teams (5 to 7 people). Mercurial is faster, takes less disk space and full local copy allows faster logs & diffs operations. I'm not concerned by this either, as I didn't notice speed or space problems with SVN even with very large projects I'm working on. I'm seeking for your personal experiences and/or opinions from former SVN geeks. Especially regarding the changesets concept and overall performance boost you measured. UPDATE (12th Jan): I'm now convinced that it worth a try. UPDATE (12th Jun): I kissed Mercurial and I liked it. The taste of his cherry local commits. I kissed Mercurial just to try it. I hope my SVN Server don't mind it. It felt so wrong. It felt so right. Don't mean I'm in love tonight. FINAL UPDATE (29th Jul): I had the privilege to review Eric Sink's next book called Version Control by Example. He finished to convince me. I'll go for Mercurial.

• Unable to decode hex values in javascript tooltip

  - by staudk27

  Hi all, I have quite the process that we go through in order to display some e-mail communications in our application. Trying to keep it as general as possible... -We make a request to a service via XML -Get the XML reply string, send the string to a method to encode any invalid characters as follows: public static String convertUTF8(String value) { char[] chars = value.toCharArray(); StringBuffer retVal = new StringBuffer(chars.length); for (int i = 0; i < chars.length; i++) { char c = chars[i]; int chVal = (int)c; if (chVal > Byte.MAX_VALUE) { retVal.append("&#x").append(Integer.toHexString(chVal)).append(";"); } else { retVal.append(c); } } return retVal.toString(); } We then send that result of a string to another method to remove any other invalid characters: public static String removeInvalidCharacters(String inString) { if (inString == null){ return null; } StringBuffer newString = new StringBuffer(); char ch; char c[] = inString.toCharArray(); for (int i = 0; i < c.length; i++) { ch = c[i]; // remove any characters outside the valid UTF-8 range as well as all control characters // except tabs and new lines if ((ch < 0x00FD && ch > 0x001F) || ch == '\t' || ch == '\n' || ch == '\r') { newString.append(ch); } } return newString.toString(); } This string is then "unmarshal'ed" via the SaxParser The object is then sent back to our Display action which generated the response to the calling jsp/javascript to create the page. The issue is some text can contain characters which can't be processed correctly. The following is eventually rendered on the JSP just fine: <PrvwCommTxt>This is a new test. Have a*&amp;#xc7;&amp;#xb4;)&amp;#xa1;.&amp;#xf1;&amp;#xc7;&amp;#xa1;.&amp;#xf1;*&amp;#xc7;&amp;#xb4;)...</PrvwCommTxt> Which shows up as "This is a new test. Have a*Ç´)¡.ñÇ¡." in the browser. -The following shows up in a tooltip while hovering over the above text: <CommDetails>This is a new test. Have a*Ç´)¡.ñÇ¡.ñ*Ç´)¡.ñ*´)(¡.ñÇ(¡.ñÇ* Wonderful Day!</CommDetails> This then shows up incorrectly when rendered in the tooltip javascript with all the HEX values and not being rendered correctly. Any suggestions on how to make the unknown characters show correctly in javascript?

• What encoding to use for exporting to CSV?

  - by Michael Borgwardt

  I'm developing a java app that exports data to CSV files, intended to be opened in Excel by end users. We just noticed that the export function uses Java's platform default encoding. This causes umlaut characters to be lost and unit test to fail on the build server (which is configured to have US-ASCII as its platform default encoding exactly to catch such potential problems). The question is: which would be the best encoding to use? How does Excel determine what encoding to use? Does it use something platform-specific that presumably matches Java's platform default? I'm currently leaning towards hardcoding Cp1252 - that should cover the target machines (the deployment environment is actually specified) and would fix the test problem. From googling around, Excel does not seem to handle UTF-8 well, so that's out, and sticking to the platform default encoding would require some sort of workaround hack for the tests.

• C# Generics Casting

  - by Nippysaurus

  Visual sutdio 2008 has the ability to automatically create unit test stubs. I have used this to create some basic unit tests, but I am confused by something: private class bla : BaseStoreItem { // } /// <summary> ///A test for StoreData ///</summary> public void StoreDataTestHelper<T>() where T : BaseStoreItem { FileStore<T> target = new FileStore<T>(); // TODO: Initialize to an appropriate value BaseStoreItem data = new bla(); target.StoreData(data); } [TestMethod()] public void StoreDataTest() { //Assert.Inconclusive("No appropriate type parameter is found to satisfies the type constraint(s) of T. " + // "Please call StoreDataTestHelper<T>() with appropriate type parameters."); StoreDataTestHelper<bla>(); } Why do I get "Error: Cannot convert type 'StorageUnitTests.FileStoreTest.bla' to 'T'" when T is type "bla"? I know "bla" is not a good function name, but its just an example.

• Can NSUserDefaults be used for pausing the application during a phone call ?

  - by Anil Kumar

  Friends, currently I dont have iphone to test and using Simulator for testing purposes. I am Just curious to know whether an application continues to run even after a phone call.. here i have no option to test this from simulator. If it terminates then how can i pause things.. and continue after a phone call. Is NSUserDefaults can be used for my case. As far I understood NSuserDefaults are used to store data that is required when the App is next time loaded. But here I dont want my App to terminate instead pause until Call ends and continue as uninterrupted later. Please clear me about this. Sorry I am still a beginner so I request for no harsh replies if my question looks stupid. Thanks in Advance

• WP7 databinding displays int but not string?

  Whenever I test my app.. it binds the data from Note class and displays it if it isn't a string. But for the string variables it wont bind. What am I doing wrong?

• define method for instance of class

  - by aharon

  Let there be class Example defined as: class Example def initialize(test='hey') self.class.send(:define_method, :say_hello, lambda { test }) end end On calling Example.new; Example.new I get a warning: method redefined; discarding old say_hello. This, I conclude, must be because it defines a method in the actual class (which makes sense, from the syntax). And that, of course, would prove disastrous should there be multiple instances of Example with different values in their methods. Is there a way to create methods just for the instance of a class from inside that instance? Thanks so much.

• Upload image using CURL + PHP via remote form

  - by user253530

  I have a few images that i need to upload using an online form. So far here's my code $info = array('test title','1234','virginia','@'.realpath('e:\wamp\www\1.jpg'),'@'.realpath('e:\wamp\www\2.jpg'),'@'.realpath('e:\wamp\www\3.jpg'),'@'.realpath('e:\wamp\www\4.jpg'),'test description'); $post->postAd($url, $info); The $info array is processed in the postAd method and it's being sent as an associative array using a method from a Curl class i have (it has been tested and worked nicely with everything i needed to do so far with curl). The problem is that the data is completed correctly on the form but the images are not uploaded. Can anyone help with advices/code/guidance?

• Outlook AppointmentItem - How do I programmatically add RTF to its Body?

  - by Stuart Harris

  I would like to set the Body of an AppointmentItem to a string of RTF that contains an embedded image. Setting Microsoft.Office.Interop.Outlook.AppointmentItem.Body results in the RTF appearing as-is in the appointment. I have tried using Redemption which wraps the appointment and exposes an RTFBody property, but the RTF formatting (including the image) is lost. In this example (which doesn't have an embedded image) the RTF appears in the document as-is. Has anyone managed to do this? var appointment = (AppointmentItem)app.CreateItem(OlItemType.olAppointmentItem); appointment.Subject = "test subject"; appointment.Start = DateTime.Now; appointment.End = DateTime.Now.AddHours(1); appointment.Body = @"{\rtf1\ansi\deff0{\fonttbl{\f0 Arial;}}{\colortbl ;\red0\green0\blue255;}\pard\cf1\f0\fs24 Test}"; appointment.Save();

• Blackberry 507 Erorr

  - by Haoest

  I didn't think it would be so catastrophic when I typed JavaLoader -usb wipe -a into the command line with my blackberry 8800 test device. It reboots with a 507 error that I can't get rid of. I have Blackberry Desktop Manager 4.6, which is normally what I use to upload my test apps, but this time I go to Application Loader, hitting start gives me that dialog box that shows me the list of 1 USB connection "PIN: xxx" with a password field (which I have no idea of,) then it says "connecting to boot ROM" then stops at the message: A connection to the device can not be established... Now is there a hard physical way of resetting my blackberry 8800, please?

• Entity Framework 4.0 Unit Testing

  - by Steve Ward

  Hi, I've implemented unit testing along the lines of this article with a fake object context and IObjectSet with POCO in EF4. http://blogs.msdn.com/adonet/archive/2009/12/17/test-driven-development-walkthrough-with-the-entity-framework-4-0.aspx But I'm unsure how to implement a couple of methods on my fake object context for testing. I have CreateQuery and ExecuteFunction methods on my object context interface so that I can execute ESQL and Stored Procedures but I cant (easily) implement them in my fake object context. An alternative would be to use a test double of my repository instead of a double of my object context as suggested here: http://social.msdn.microsoft.com/Forums/en-US/adonetefx/thread/c4921443-e8a3-4414-92dd-eba1480a07ad/ But this would mean my real repository isnt being tested and would seem to just bypass the issue. Can anyone offer any recommendations?

• Constructing mocks in unit tests

  - by Flynn1179

  Is there any way to have a mock constructed instead of a real instance when testing code that calls a constructor? For example: public class ClassToTest { public void MethodToTest() { MyObject foo = new MyObject(); Console.WriteLine(foo.ToString()); } } In this example, I need to create a unit test that confirms that calling MethodToTest on an instance of ClassToTest will indeed output whatever the result of the ToString() method of a newly created instance of MyObject. I can't see a way of realistically testing the 'ClassToTest' class in isolation; testing this method would actually test the 'myObject.ToString()' method as well as the MethodToTest method.
