  • iPad/iPhone uiSearchbar transparent background

    - by Tom
    I know this questions was asked(and solved) before, but this wont work for me. as a matter of fact, I had it already solved, but this issue came back out of nowhere and struck me on the head. I am not able to set the background of my UISearchBar transparent. I was always using: searchBar.backgroundColor = [UIColor clearColor]; [[searchBar.subviews objectAtIndex:0] removeFromSuperview]; and it worked nicely... but suddenly it stopped. could be since I upgraded my xcode-version but I am not sure. I spent a couple of hours already investigating this.. Is somebody out there to do this? please point me in the right direction. thanks heaps!!! best regards T

  • Polymorphic Behavior in VB6

    - by Tom Tresansky
    I recently noticed the CallByName keyword in VB6. Since this takes a object, procedure name, "call type" and arguments array, can this be used to "fake" some types of polymorphic behavior? I can make 2 classes, class A and B, each with the same method Foo, and do: Dim list As New Collection Dim instanceA As New ClassA Dim instanceB As New ClassB Dim current As Object Call list.Add(instanceA) Call list.Add(instanceB) For Each current in list Call CallByName(current, "methodName", vbMethod) Next Anyone done this before? Problems? Horrible idea or genius idea? Implications? Unintended consequences?

  • Can I reset a forgotten owner password with iText?

    - by Tom Hubbard
    With iText I can use Java to open a pdf and write it. If the pdf has an owner password I can still open it but it can not be written. Clearly the content is readable, it seems like at that point you could simply write the document to a new file. iText doesn't allow this, it throws a bad password exception. Is there a way around this?

  • Select no tabs in a UITabBar

    - by Tom
    Hi, I'm trying to select no tabs at all in my application. At first the first tab is selected, but I'd like to deselect it so no tabs at all would be selected. Don't ask me why, it's just that way the client wants it! hehe Thanks for your help! PS: I already tried: // rootController = UITabBarController rootController.tabBar.selectedItem = 0; rootController.tabBar.selectedItem = nil; [rootController setSelectedIndex:[rootController.items objectAtIndex:0]]; [rootController setSelectedIndex:nil]; [rootController setSelectedIndex:0]; // That one works : (but I can't select 0 or -1 for instance) [rootController setSelectedIndex:2]; Any ideas? Thanks again!

  • Is there a version of the .Net Redistributable bundled with all supported versions of Windows?

    - by Tom the Junglist
    Hi there, Is there a specific version of .Net that I can target that is bundled with all versions of Windows of XP SP2 and higher? We are trying to create a simple setup stub without having to resort to a low-level C/C++ app... currently something is cooked up in VB6, but there's a fair amount of low-level network code that I would much rather rewrite in .Net -- which would be trivial if only we could rely on the presence of a given version.

  • Make is more OOPey - good structure?

    - by Tom
    Hi, I just want advice on whether I could improve structure around a particular class which handles all disk access functions The structure of my program is that I have a class called Disk which gets data from flatfiles and databases on a, you guessed it, hard disk drive. I have functions like LoadTextFileToStringList, WriteStringToTextFile, DeleteLineInTextFile etc which are kind of "generic methods" In the same class I also have some more specific methods such as GetXFromDisk where X might be a particular field in a database table/query. Should I separate out the generic methods from the specialised. Should I make another class which inherits the generic methods. At the moment my class is static as there is no need to have an internal state of the class. I'm not really OOPing am I? Thanks Thomas

  • ASP.NET Memory Usage in IIS is FAR greater than in DevEnv. Is this normal?

    - by Tom
    Greetings! I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process. There is no database access, no session storage, no caching, but an in-memory list of about 100 objects (total 1MB of data), plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS. The issue: When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly. When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page. Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic. Is this normal? If I bump the server RAM up to 4GB, will that be enough? Will multiple users require even more memory? Could the culprit be AJAX or the list of objects? Thanks for any insight you can provide.

  • Will SQL Server Partitioning increase performance without changing filegroups

    - by Tom
    Scenario I have a 10 million row table. I partition it into 10 partitions, which results in 1 million rows per partition but I do not do anything else (like move the partitions to different file groups or spindles) Will I see a performance increase? Is this in effect like creating 10 smaller tables? If I have queries that perform key lookups or scans, will the performance increase as if they were operating against a much smaller table? I'm trying to understand how partitioning is different from just having a well indexed table, and where it can be used to improve performance. Would a better scenario be to move the old data (using partition switching) out of the primary table to a read only archive table? Is having a table with a 1 million row partition and a 9 million row partition analagous (performance wise) to moving the 9 million rows to another table and leaving only 1 million rows in the original table?

  • Change SVN Path Entirely

    - by Tom
    Hi Guys, We have an SVN at http:/XX.XXX.XXX.XXX:1111/svn/AB/ - and the first two folders of the SVN are like http:/XX.XXX.XXX.XXX:1111/svn/AB/abc/filefolder/ The problem is we want to move the entire svn to get rid of /abc/filefolder/ - as the entire project sits under /abc/filefolder/ [created long ago and never bothered to change] (que stupid yes yes) How would we could about fixing this so we dont loose logs etc ? We dont want to have to export and create a new svn - since then we loose all our log files. But we want to "move" the svn root so for example it becomes From: http:/XX.XXX.XXX.XXX:1111/svn/AB/abc/filefolder/documents/ To: http:/XX.XXX.XXX.XXX:1111/svn/AB/documents/ Any help appreciated ? [ps - yes had to remove http:// due to link restriction]

  • Reports in Java. What tool to use?

    - by Tom
    Hi, I need to create some reports, in different formats (xls, pdf, rtf). I am currently using JasperReports, in conjunction with IReport. I have no major complaints about it (except for the cases when IReport messes up my xml files), but i've been having some problems with it, when exporting to xls files and with some "special" characters, such as '&'. Is there a widely use alternative? Is JasperReports the right choice?

  • Looking for detailed explanation of Hibernate UserType methods for mutable objects

    - by Tom
    I am creating a custom UserType class in Hibernate. The specific case is for an HL7v3 clinical document (I work in health IT). It is a mutable object and most of the documentation around the Hibernate UserType interface seems to center around immutable types. I want a better understanding of how and when the interface methods are used, specifically: assemble - why two parameters (one Serializable, one Object)? What is the use case for this method? disassemble - should I just implement this method to return a serializable form (e.g. String representation)? When and how is this method invoked? equals - is this for update? read? contention? dirty reads? What are the consequences of simply returning false in most cases? replace - I really don't understand where the three Object parameters come from, when this method is invoked, and what Hibernate expects to return, or how that return value is used. Any pointers would be appreciated. I've searched and read all I can find on the subject, but have not found much documentation at all explaining how these methods are used for mutable objects.

  • Java Apache Commons users

    - by Tom Brito
    Is there anything in apache commons to convert a Object to byte array, like the following method does? public static byte[] toByteArray(Object obj) throws IOException { ByteArrayOutputStream baos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(obj); oos.flush(); byte[] data = baos.toByteArray(); return data; } [try-finally block closing buffers were omitted to simplify]

  • Convert Existing Eclipse Project to Maven Project

    - by Tom G
    For a project at work, we're considering using the Maven plugin for Eclipse to automate our builds. Right now the procedure is far more complicated than it ought to be, and we're hoping that Maven will simplify things to a one-click build. My question is, is there a wizard or automatic importer for converting an existing Eclipse Java project to a Maven project, using the Maven plugin? Or should I create a new Maven project and manually copy over all source files, libs, etc.

  • What are the options for overriding Django's cascading delete behaviour?

    - by Tom
    Django models generally handle the ON DELETE CASCADE behaviour quite adequately (in a way that works on databases that don't support it natively.) However, I'm struggling to discover what is the best way to override this behaviour where it is not appropriate, in the following scenarios for example: ON DELETE RESTRICT (i.e. prevent deleting an object if it has child records) ON DELETE SET NULL (i.e. don't delete a child record, but set it's parent key to NULL instead to break the relationship) Update other related data when a record is deleted (e.g. deleting an uploaded image file) The following are the potential ways to achieve these that I am aware of: Override the model's delete() method. While this sort of works, it is sidestepped when the records are deleted via a QuerySet. Also, every model's delete() must be overridden to make sure Django's code is never called and super() can't be called as it may use a QuerySet to delete child objects. Use signals. This seems to be ideal as they are called when directly deleting the model or deleting via a QuerySet. However, there is no possibility to prevent a child object from being deleted so it is not usable to implement ON CASCADE RESTRICT or SET NULL. Use a database engine that handles this properly (what does Django do in this case?) Wait until Django supports it (and live with bugs until then...) It seems like the first option is the only viable one, but it's ugly, throws the baby out with the bath water, and risks missing something when a new model/relation is added. Am I missing something? Any recommendations?

  • Where is the visual studio 2010 setup and deployment project template

    - by Tom Brown
    In VS 2008, when I create a project I can add a setup project easily. File-Add-New Project... then in Project types: select Other Project Types-Setup and Deployment - and there are a whole load of installed templates - including Setup Project to create an MSI installer. But in VS 2010 - there are no templates in the Setup and Deployment - I'm using the Pro edition, not Express or beta: Is this the same for you - or do I have a duff installation of VS 2010? Otherwise how do I create an MSI installer for my projects?

  • Using images and css file for a generated HTML UIWebView

    - by Tom
    Hi! I'm generating an HTML file for an app, and in this HTML file there's a link to a stylesheet and one to an image. Here's what I tried so far: NSMutableString *toReturn = [NSMutableString stringWithCapacity:100]; NSString *cssPath = [[NSBundle mainBundle] pathForResource:@"etapes.css" ofType:nil]; [toReturn appendFormat:@"<html><head><title></title><link href=\"%@\" media=\"all\" rel=\"stylesheet\" type=\"text/css\" /></head><body>", cssPath]; It generates the right full path to the right file, this is okay if I want to access it on my mac, but on the simulator or my iPhone it doesn't point to the right place at all... Do you have any idea of how could I make this? Thanks

  • Is there a simpler way to convert a byte array to a 2-byte-size hexadecimal string?

    - by Tom Brito
    Is there a simpler way of implement this? Or a implemented method in JDK or other lib? /** * Convert a byte array to 2-byte-size hexadecimal String. */ public static String to2DigitsHex(byte[] bytes) { String hexData = ""; for (int i = 0; i < bytes.length; i++) { int intV = bytes[i] & 0xFF; // positive int String hexV = Integer.toHexString(intV); if (hexV.length() < 2) { hexV = "0" + hexV; } hexData += hexV; } return hexData; } public static void main(String[] args) { System.out.println(to2DigitsHex(new byte[] {8, 10, 12})); } the output is: "08 0A 0C" (without the spaces)

  • Exclude files only in "release" in VS2008 config

    - by Tom
    Hi Guys, I was wondering how to "Exclude" individual files in the "release" web.csproj config of my solution. I've seen other answers and they all feature "include" - but this is not what I am wanting to achieve. I only want to exclude around 10-15 files from a "release" package ? I don't want to manually edit the web.csproj file - so is there any way I can do this via web.config or ? How would I go about doing this ?

  • Exactly clone an object in javascript

    - by Tom
    Hi, I tried to exactly clone an object in javascript. I know the following solution using jquery: var newObject = jQuery.extend({}, oldObject); // Or var newObject = jQuery.extend(true, {}, oldObject); but the problem with that is, that the objects type gets lost: var MyClass = function(param1, param2) { alert(param1.a + param2.a); }; var myObj = new MyClass({a: 1},{a: 2}); var myObjClone = jQuery.extend(true, {}, myObj); alert(myObj instanceof MyClass); // => true alert(myObjClone instanceof MyClass); // => false Is there any solution to get true on the second alert?

  • Use a "User Macro" in .vcproj RelativePath

    - by Tom Leys
    Inside .vcproj files There is a list of all source files in your project. How can we use a macro to specify the path to a source file? If we do this: <File RelativePath="$(Lib3rdParty)\Qt\qtwinmigrate-2.5-commercial\src\qmfcapp.cpp"> </File> The compiler cannot find the folder: qmfcapp.cpp c1xx : fatal error C1083: Cannot open source file: '.\$(lib3rdparty)\qt\qtwinmigrate- 2.5-commercial\src\qmfcapp.cpp': No such file or directory As you can see, our project compiles in several source files from QT. QT lives inside a folder of external libraries, and we don't want hardcode the path from our project to that folder (we have a very large solution)
