• Programming tips for writing document editors?

  - by Tesserex

  I'm asking this because I'm in the process of writing two such editors for my Mega Man engine, one a tileset editor, and another a level editor. When I say document editor, I mean the superset application type for things like image editors and text editors. All of these share things like toolbars, menu options, and in the case of image editors, and my apps, tool panes. We all know there's tons of advice out there for interface design in these apps, but I'm wondering about programming advice. Specifically, I'm doubting my code designs with the following things: Many menu options toggle various behaviors. What's the proper way to reliably tie the checked state of the option with the status of the behavior? Sometimes it's more complicated, like options being disabled when there's no document loaded. More and more consensus seems to be against using MDI, but how should I control tool panes? For example, I can't figure out how to get the panels to minimize and maximize along with the main window, like Photoshop does. When tool panels are responsible for a particular part of the document, who actually owns that thing? The main window, or the panel class? How do you do communication between the tool panels and the main window? Currently mine is all event based but it seems like there could be a better way. This seems to be a common class of gui application, but I've never seen specific pointers on code design for them. Could you please offer whatever advice or experience you have for writing them?

• asp.net Membership : Extending Role membership?

  - by mark smith

  Hi there, I am been taking a look at asp.net membership and it seems to provide everything that i need but i need some kind of custom Role functionality. Currently i can add user to a role, great. But i also need to be able to add Permissions to Roles.. i.e. Role: Editor Permissions: Can View Editor Menu, Can Write to Editors Table, Can Delete Entries in Editors Table. Currently it doesn't support this, The idea behind this is to create a admin option in my program to create a role and then assign permissions to a role to say "allow the user to view a certain part of the application", "allow the user to open a menu item" Any ideas how i would implement soemthing like this? I presume a custom ROLE provider but i was wondering if some kind of framework extension existed already without rolling my own? Or anybody knows a good tutorial of how to tackle this issue? I am quite happy with what asp.net SQL provider has created in terms of tables etc... but i think i need to extend this by adding another table called RolesPermissions and then I presume :-) adding some kind of enumeration into the table for each valid permission?? THanks in advance

• Problem with Unit testing of ASP.NET project (NullReferenceException when running the test)

  - by Alex

  Hi, I'm trying to create a bunch of MS visual studio unit tests for my n-tiered web app but for some reason I can't run those tests and I get the following error - "Object reference not set to an instance of an object" What I'm trying to do is testing of my data access layer where I use LINQ data context class to execute a certain function and return a result,however during the debugging process I found out that all the tests fail as soon as they get to the LINQ data context class and it has something to do with the connection string but I cant figure out what is the problem. The debugging of tests fails here(the second line): public EICDataClassesDataContext() : base(global::System.Configuration.ConfigurationManager.ConnectionStrings["EICDatabaseConnectionString"].ConnectionString, mappingSource) { OnCreated(); } And my test is as follows: TestMethod()] public void OnGetCustomerIDTest() { FrontLineStaffDataAccess target = new FrontLineStaffDataAccess(); // TODO: Initialize to an appropriate value string regNo = "jonh"; // TODO: Initialize to an appropriate value int expected = 10; // TODO: Initialize to an appropriate value int actual; actual = target.OnGetCustomerID(regNo); Assert.AreEqual(expected, actual); } The method which I call from DAL is: public int OnGetCustomerID(string regNo) { using (LINQDataAccess.EICDataClassesDataContext dataContext = new LINQDataAccess.EICDataClassesDataContext()) { IEnumerable<LINQDataAccess.GetCustomerIDResult> sProcCustomerIDResult = dataContext.GetCustomerID(regNo); int customerID = sProcCustomerIDResult.First().CustomerID; return customerID; } } So basically everything fails after it reaches the 1st line of DA layer method and when it tries to instantiate the LINQ data access class... I've spent around 10 hours trying to troubleshoot the problem but no result...I would really appreciate any help! UPDATE: Finally I've fixed this!!!!:) I dont know why but for some reasons in the app.config file the connection to my database was as follows: AttachDbFilename=|DataDirectory|\EICDatabase.MDF So what I did is I just changed the path and instead of |DataDirectory| I put the actual path where my MDF file sits,i.e C:\Users\1\Documents\Visual Studio 2008\Projects\EICWebSystem\EICWebSystem\App_Data\EICDatabase.mdf After I had done that it worked out!But still it's a bit not clear what was the problem...probably incorrect path to the database?My web.config of ASP.NET project contains the |DataDirectory|\EICDatabase.MDF path though..

• How to append new elements to Xml from a stream

  - by Wololo

  I have a method which returns some xml in a memory stream private MemoryStream GetXml() { XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; using (MemoryStream memoryStream = new MemoryStream()) { using (XmlWriter writer = XmlWriter.Create(memoryStream, settings)) { writer.WriteStartDocument(); writer.WriteStartElement("root"); writer.WriteStartElement("element"); writer.WriteString("content"); writer.WriteEndElement(); writer.WriteEndElement(); writer.WriteEndDocument(); writer.Flush(); } return memoryStream; } } In this example the format of the xml will be: <?xml version="1.0" encoding="utf-8"?> <root> <element>content</element> </root> How can i insert a new element under the root e.g <?xml version="1.0" encoding="utf-8"?> <root> <element>content</element> ----->New element here <------ </root> EDIT: Also please suggest the most efficient method as returning a memorystream may not be the best solution. The final xml will be passed to a custom HttpHandler so what are the best options for writing the output? context.Response.Write vs context.Response.OutputStream

  Following instructions from the two sites below, I've installed tomcat6 and solr 1.4 http://gist.github.com/204638 https://wiki.fourkitchens.com/display/TECH/Solr+1.4+on+Ubuntu+9.10+and+CentOS+5 I have successfully got it up and running on a server running 9.04 with multicore support, but on the 10.04 I can't seem to get it to work. I am able to reach localhost:xxxx/solr/ on the 10.04 box and see a single link to the Solr Admin, but following the link takes me to a 404 page with the following output: /solr/admin/ HTTP Status 404 - missing core name in path The requested resource (missing core name in path) is not available I am also unable to access /solr/site1/ as I would except - it similarly returns a 404 <!-- from /var/solr/solr.xml, site dirs exist --> <cores adminPath="/admin/cores"> <core name="site1" instanceDir="site1" /> <core name="site2" instanceDir="site2" /> </cores> <!-- from /etc/tomcat6/Catalina/localhost/solr.xml --> <Context docBase="/var/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/var/solr" override="true" /> </Context>

• Do servlet containers prevent web applications from causing each other interference and how do they do it?

  - by chrisbunney

  I know that a servlet container, such as Apache Tomcat, runs in a single instance of the JVM, which means all of its servlets will run in the same process. I also know that the architecture of the servlet container means each web application exists in its own context, which suggests it is isolated from other web applications. As depicted here: Accepting that each web application is isolated, I would expect that you could create 2 copies of an identical web application, change the names and context paths of each (as well as any other relevant configuration), and run them in parallel without one affecting the other. The answers to this question appear to support this view. However, a colleague disagrees based on their experience of attempting just that. They took a web application and tried to run 2 separate instances (with different names etc) in the same servlet container and experienced issues with the 2 instances conflicting (I'm unable to elaborate more as I wasn't involved in that work). Based on this, they argue that since the web applications run in the same process space, they can't be isolated and things such as class attributes would end up being inadvertently shared. This answer appears to suggest the same thing The two views don't seem to be compatible, so I ask you: Do servlet containers prevent web applications deployed to the same container from conflicting with each other? If yes, How do they do this? If no, Why does interference occur? and finally, Under what circumstances could separate web applications conflict and cause each other interference?, perhaps scenarios involving resources on the file system, native code, or database connections?

• Can I build this XPath query dynamically in XSLT?

  - by Martin Doms

  I have a document that looks something like <root> <element> <subelement1 /> <subelement2 /> </element> <element> <subelement2 /> <subelement1 /> </element> </root> In my XSLT sheet in the context of /element[2]/[someNode] I want to get a number that represents the distance of /element[1]/[someNode] (ie, the number of preceding siblings of /element1/[someNode]). For example, in the context of /element[2]/subelement1 I'd like to have some way to get the number 2, the distance from /element[1] to /element[1]/subelement2. I only ever need the distance of the given node name from the first instance of . Intuitively I thought I could construct this like <xsl:variable name="nodename" select="name()" /> <xsl:value-of select="/element[1]/$nodename/preceding-sibling::*" /> but unfortunately this sheet doesn't compile. Is what I'm trying to achieve possible in XSLT?

• How to change one Button background in a gridview? -- Android

  - by Tstop Studios

  I have a GridView with 16 ImageView buttons. My program makes a random number and when the user clicks a button in the gridview, i want it to take the random number (0-15) and set the background of the tile with the same position as the random number (0-15) to a different image. How can I just change one of the buttons background? Here's my code so far: public class ButtonHider extends Activity { Random random = new Random(); int pos; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.button_hider); pos = random.nextInt(15); GridView gridview = (GridView) findViewById(R.id.gvBH); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position, long id) { pos = random.nextInt(16); if (position == pos) { Toast.makeText(ButtonHider.this, "Found Me!", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(ButtonHider.this, "Try Again!!", Toast.LENGTH_SHORT).show(); } } }); } public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return 16; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some // attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(100, 100)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(15, 15, 15, 15); } else { imageView = (ImageView) convertView; } imageView.setImageResource(R.drawable.bh_b); return imageView; } } }

• android : bluetooth support

  - by Puneet kaur

  i have coded for bluetooth via defining a user task ,which will search the devices in background and set the list on foreground after finishing the search . but sometimes i am getting the data in adapter as "nodevice" "device1" "device2" ...... the problem here is why it is always filling the no device in the list and after that fill the device in list .. private BroadcastReceiver mBlueToothInfoDiscoveryListener = new BroadcastReceiver() { /** * This is an overridden function called by the framework whenever there * is some broadcast message for Bluetooth info discovery listener */ @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); // When discovery finds a device if (BluetoothDevice.ACTION_FOUND.equals(action)) { // Get the BluetoothDevice object from the Intent BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); // If it's already paired, skip it, because it's been listed // already if (device.getBondState() != BluetoothDevice.BOND_BONDED) { mNewBtDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress()); } // When discovery is finished, change the Activity title } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) { setProgressBarIndeterminateVisibility(false); setTitle("device list"); if (mNewBtDevicesArrayAdapter.getCount() == 0) { String noDevices = "No devices found"; mNewBtDevicesArrayAdapter.add(noDevices); } } } }; but here why it is sometimes going into else option on start and filling the list with no device then to if part again ... when devices are already on .

• Groovy on Grails: GORM and BitSets?

• Use the repository pattern when using PLINQO generated data?

  - by Chad

  I'm "upgrading" an MVC app. Previously, the DAL was a part of the Model, as a series of repositories (based on the entity name) using standard LINQ to SQL queries. Now, it's a separate project and is generated using PLINQO. Since PLINQO generates query extensions based on the properties of the entity, I started using them directly in my controller... and eliminated the repositories all together. It's working fine, this is more a question to draw upon your experience, should I continue down this path or should I rebuild the repositories (using PLINQO as the DAL within the repository files)? One benefit of just using the PLINQO generated data context is that when I need DB access, I just make one reference to the the data context. Under the repository pattern, I had to reference each repository when I needed data access, sometimes needing to reference multiple repositories on a single controller. The big benefit I saw on the repositories, were aptly named query methods (i.e. FindAllProductsByCategoryId(int id), etc...). With the PLINQO code, it's _db.Product.ByCatId(int id) - which isn't too bad either. I like both, but where it gets "harrier" is when the query uses predicates. I can roll that up into the repository query method. But on the PLINQO code, it would be something like _db.Product.Where(x = x.CatId == 1 && x.OrderId == 1); I'm not so sure I like having code like that in my controllers. Whats your take on this?

• struts2 trim all string obtained from forms

  - by aelkin

  Hi All, I develop web application using struts2. I want to improve getting string from forms. For this need trim all string and if obtained string is empty then set null to field. For this, I created StringConverter. public class StringConverter extends StrutsTypeConverter { @Override public Object convertFromString(Map context, String[] strings, Class toClass) { if (strings == null || strings.length == 0) { return null; } String result = strings[0]; if (result == null) { return null; } result = result.trim(); if (result.isEmpty()) { return null; } return result; } @Override public String convertToString(Map context, Object object) { if (object != null && object instanceof String) { return object.toString(); } return null; } } Next, I added row to xwork-conversion.properties java.lang.String=com.mypackage.StringConverter Thats all. But I did not get the desired result. convertToString() method is called when jsp build form, but convertFromString() doesn't invoke. What I do wrong? How can I get the same behaviour using another way? Please, not offer solutions such as: remove the value of such form elements using javascript. create util method which will make it using reflection. Then call it for each form bean. Thanks in advance, Alexey.

• Creating a window manager type overlay for Mac OS X

  - by zorg1379

  I want to make my own window manager for OS X, or at least give it the appearance of a new one. I have many designs written down in a book, and would like to implement them. These include altering, or even completely removing, menu bars, creating entirely new guis for switching applications, etc. I know that OS X does not have a window manager, and that basically the functions that an X11 window manager would perform are done by Carbon, Cocoa, the Dock application, and the window server. I've read that it would take an incredible amount of reverse engineering to write my own api, etc. at the hardware level. I am still not that good at programming though, and don't have that kind of time. That's why I was thinking of maybe running an application on top of OS X that will function like a separate window manager - and do everything that the normal OS GUI / window manager would do. Is this possible? For example: making a custom button that would appear upon a certain key combination, that could be clicked to access a document viewer, change the time, minimize a window, etc. Is there some way to access functionality to basic tasks / actions like this without using the default OS X button controls, and implementing them with my own GUI? I am talking about more than a simple theme change, I want to completely change the user experience. This means that this application would be run in a full screen mode that blocks out default OS X menu bars. I've heard something about using graphics architectures to plug in your own window manager? Would this be an option too? If so, how would I go about doing that? Thank you,

  Please read my question carefully and reply me. I have two tables as table1 and table2. In table1 i have columns as AddressID(Primary Key),Address1,Address2,City In table2 i have columns as ContactID(Primary Key),AddressID(Foriegn Key),Last Name,First Name. By using join operation i can retrive data from both the tables. I created a Model in my MVC Application.I can see both the tables in enitity editor. In the ViewData folder of my solution explorer i created two class as ContactViewData.cs and SLXRepository.cs In the ContactViewData.cs i have following code public IEnumerable<CONTACT> contacts { get; set; } In the SLXRepository.cs i have following code public IEnumerable<CONTACT> GetContacts() { var contact = ( from c in context.CONTACT join a in context.ADDRESS on c.ADDRESSID equals a.ADDRESSID select new { a.ADDRESS1, a.ADDRESS2, a.CITY, c.FIRSTNAME, c.LASTNAME } ); return contact; } I am getting the error in return type Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Collections.Generic.IEnumerable'. An explicit conversion exists (are you missing a cast?)

• Multi-tenant Access Control: Repository or Service layer?

  - by FreshCode

  In a multi-tenant ASP.NET MVC application based on Rob Conery's MVC Storefront, should I be filtering the tenant's data in the repository or the service layer? 1. Filter tenant's data in the repository: public interface IJobRepository { IQueryable<Job> GetJobs(short tenantId); } 2. Let the service filter the repository data by tenant: public interface IJobService { IList<Job> GetJobs(short tenantId); } My gut-feeling says to do it in the service layer (option 2), but it could be argued that each tenant should in essence have their own "virtual repository," (option 1) where this responsibility lies with the repository. Which is the most elegant approach: option 1, option 2 or is there a better way? Update: I tried the proposed idea of filtering at the repository, but the problem is that my application provides the tenant context (via sub-domain) and only interacts with the service layer. Passing the context all the way to the repository layer is a mission. So instead I have opted to filter my data at the service layer. I feel that the repository should represent all data physically available in the repository with appropriate filters for retrieving tenant-specific data, to be used by the service layer. Final Update: I ended up abandoning this approach due to the unnecessary complexities. See my answer below.

• Error while using JSFUnit/HtmlUnit/CSSParser

  - by brianf

  We've just recently converted our project to using Maven for builds and dependency management, and after the conversion I'm getting the following exception while trying to run any JSFUnit tests in my project. Exception class=[java.lang.UnsupportedOperationException] com.gargoylesoftware.htmlunit.ScriptException: CSSRule com.steadystate.css.dom.CSSCharsetRuleImpl is not yet supported. at com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine$HtmlUnitContextAction.run(JavaScriptEngine.java:527) at net.sourceforge.htmlunit.corejs.javascript.Context.call(Context.java:537) ... All the dependencies and JARs for JSFUnit were pulled with Maven using the JBoss repository (http://repository.jboss.com/maven2/). We're using the following dependencies in the project: jboss-jsfunit-core 1.2.0.Final jboss-jsfunit-richfaces 1.2.0.Final richfaces-ui 3.3.2.GA openfaces 2.0 JSF 1.2_12 Facelets 1.1.14 Before the dependencies were being managed by Maven, we were able to run our JSFUnit tests just fine. I was able to semi-fix the issue by using a ss_css2.jar file that someone had tucked into our WEB-INF/lib directory (from before the Maven conversion). I'm hoping to find out if there's something else I can do to fix the dependencies in Maven rather than resorting to managing some of the dependencies myself.

• Can't disable method parenthesis auto-complete in Eclipse

  - by cvig

  I'm trying to disable the automatic closing of brackets in Eclipse, and while I've mostly succeeded, I can't stop the editor from inserting a closing parenthesis for a method call. The result is that when I type: myBool.equals(true); it inserts a closing parenthesis as soon as I type the opening parenthesis, and what I actually get is: myBool.equals(true);) I've disabled all of the auto-complete options in the Preferences - Java - Editor - Typing menu, as well as Preferences - Java - Editor - Content Assist - Fill method arguments and show guessed arguments. I also disabled the smart insert mode option under the Edit menu. Is there another option somewhere else I need to use to stop Eclipse from doing this? This is with Eclipse 3.5.2 (Build ID M20100211-1343) in case it matters. Edited to add: I should also mention that this only happens if I wait for the "intellisense" pop-up with suggested method names to appear after I type the period. If I just continuously type the code without waiting for the suggestion box to appear, the closing parenthesis doesn't get inserted.

• Help with php code - need to add condition to make one link https

  - by Kaskade

  Hi, I have a wordpress blog and I need to make one of the pages secure. I have been told to make the link to that page point to https://claimpage.html as opposed to http://claimpage.html. The problem is I don't actually create the menu that links the user to the individual pages. This is done automatically by the code in the background. I think I need to put in some sort of an IF statement, saying, if the title of the page is "claim now" then use https otherwise use http. I found this code in the header.php so I think my changes need to go in here but I'm not really sure what to do. <div id="navbar"> <ul class="menu"> <li class="<?php if ( is_home() ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>"><a href="<?php echo get_settings('home'); ?>"><?php _e('Home'); ?></a></li> <?php wp_list_pages('sort_column=id&depth=1&title_li='); ?> <?php wp_register('<li>','</li>'); ?> </ul> </div> <!-- end of #navbar --> Any suggestions as to how I can make one page that I know the title and url or https while the others are kept using normal http? The site is hosted on a secure server so I do have an ssl certificate.

• Need some help/advice on WCF Per-Call Service and NServiceBus interop.

  - by Alexey

  I have WCF Per-Call service wich provides data for clients and at the same time is integrated with NServiceBus. All statefull objects are stored in UnityContainer wich is integrated into custom service host. NServiceBus is configured in service host and uses same container as service instances. Every client has its own instance context(described by Juval Lowy in his book in chapter about Durable Services). If i need to send request over bus I just use some kind of dispatcher and wait response using Thread.Sleep().Since services are per-call this is ok afaik. But I am confused a bit about messages from bus, that service must handle and provide them to clients. For some data like stock quotes I just update some kind of statefull object and and then, when clients invoke GetQuotesData() just provide data from this object. But there are numerous service messages like new quote added and etc. At this moment I have an idea to implement something like "Postman daemon" =)) and store this type of messages in instance context. Then client will invoke "GetMail()",recieve those messages and parse them. Problem is that NServiceBus messages are "Interface based" and I cant pass them over WCF, so I need to convert them to types derieved from some abstract class. Dunno what is best way to handle this situation. Will be very gratefull for any advice on this. Thanks in advance.

• System.ArgumentException: Invalid hex character at DecryptAssemblyResource

  - by Radu094

  My webapp is trowing these exceptions intermitently ever since we migrated to Mono + Apache: The error sounds more like a problem reading/processing some assembly, so I was wondering if I should be worried that there might be a problem with the hard-drive? System.ArgumentException: Invalid hex character at System.Web.Configuration.MachineKeySectionUtils.ToHexValue (Char c, Boolean high) [0x00000] in <filename unknown>:0 at System.Web.Configuration.MachineKeySectionUtils.GetBytes (System.String key, Int32 len) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.GetBytes (System.String val) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.DecryptAssemblyResource (System.String val, System.String& asmName, System.String& resName) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.ProcessRequest (System.Web.HttpContext context) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.System.Web.IHttpHandler.ProcessRequest (System.Web.HttpContext context) [0x00000] in <filename unknown>:0 at System.Web.HttpApplication+<Pipeline>c__Iterator2.MoveNext () [0x00000] in <filename unknown>:0 at System.Web.HttpApplication.Tick () [0x00000] in <filename unknown>:0 Method: Void Application_Error(System.Object, System.EventArgs) at File: at Line Number: 0 Method: Void ProcessError(System.Exception) at File: at Line Number: 0 Method: Void Tick() at File: at Line Number: 0 Method: Void Start(System.Object) at File: at Line Number: 0 Method: Void System.Web.IHttpHandler.ProcessRequest(System.Web.HttpContext) at File: at Line Number: 0 Method: Void Process(System.Web.HttpWorkerRequest) at File: at Line Number: 0 Method: Void RealProcessRequest(System.Object) at File: at Line Number: 0 Method: Void ProcessRequest(System.Web.HttpWorkerRequest) at File: at Line Number: 0 Method: Void ProcessRequest() at File: at Line Number: 0 Method: Void ProcessRequest(Mono.WebServer.MonoWorkerRequest) at File: at Line Number: 0 Method: Void ProcessRequest(Int32, System.String, System.String, System.String, System.String, System.String, Int32, System.String, Int32, System.String, System.String[], System.String[], System.Object) at File: at Line Number: 0 Method: Void InnerRun(System.Object) at File: at Line Number: 0 Method: Void Run(System.Object) at File: at Line Number: 0

• Removing a view from it's superview causes memory error - why?

  - by mystify

  Xcode is throwing an error at me: malloc: * error for object 0x103f000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I tracked down the code until a line where I do this: - (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context { // retainCount of myView is 2! (one for the retain-property, one for beeing a subview) [self.myView removeFromSuperview]; // ERROR-LINE !! self.myView = nil; } When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view! It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory. Did anyone else encounter such issues? iPhone SDK 3.0.

• .net framework execution aborted while executing CLR sproc?

  I constructed a sproc that does the equivalent of FOR XML AUTO in SQL 2008. Now that I'm testing it, it gives me a really unhelpful error msg. Any idea what this error means?

• Find position of a node within a nodeset using xpath

  - by Phil Nash

  After playing around with position() in vain I was googling around for a solution and arrived at this older stackoverflow question which almost describes my problem. The difference is that the nodeset I want the position within is dynamic, rather than a contiguous section of the document. To illustrate I'll modify the example from the linked question to match my requirements. Note that each <b> element is within a different <a> element. This is the critical bit. <root <a <bzyx</b </a <a <bwvu</b </a <a <btsr</b </a <a <bqpo</b </a </root Now if I queried, using XPath for a/b I'd get a nodeset of the four <b> nodes. I want to then find the position within that nodeset of the node that contains the string 'tsr'. The solution in the other post breaks down here: count(a/b[.='tsr']/preceding-sibling::*)+1 returns 1 because preceding-sibling is navigating the document rather than the context node-set. Is it possible to work within the context nodeset?
