• Calling method on category included from iPhone static library causes NSInvalidArgumentException

  - by Corey Floyd

  I have created a static library to house some of my code like categories. I have a category for UIViews in "UIView-Extensions.h" named Extensions. In this category I have a method called: - (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration; Calling this method works fine on the simulator on Debug configuration. However, if try to run the app on the device I get a NSInvalidArgumentException: [UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 It seems for some reason UIView-Extensions.h is not being included in the device builds. What I have checked/tried I did try to include another category for NSString, and had the same issue. Other files, like whole classes and functions work fine. It is an issue that only happens with categories. I did a clean all targets, which did not fix the problem. I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups. The static library is included in the main projects "link binary with library" group. Another project I have added the static library to works just fine. I deleted and re-added the static library with no luck -ObjC linker flag is set Any ideas? nm output libFJSCodeDebug.a(UIView-Extensions.o): 000004d4 t -[UIView(Extensions) changeColor:withDelay:duration:] 00000000 t -[UIView(Extensions) fadeInWithDelay:duration:] 000000dc t -[UIView(Extensions) fadeOutWithDelay:duration:] 00000abc t -[UIView(Extensions) firstResponder] 000006b0 t -[UIView(Extensions) hasSubviewOfClass:] 00000870 t -[UIView(Extensions) hasSubviewOfClass:thatContainsPoint:] 000005cc t -[UIView(Extensions) rotate:] 000002d8 t -[UIView(Extensions) shrinkToSize:withDelay:duration:] 000001b8 t -[UIView(Extensions) translateToFrame:delay:duration:] U _CGAffineTransformRotate 000004a8 t _CGPointMake U _CGRectContainsPoint U _NSLog U _OBJC_CLASS_$_UIColor U _OBJC_CLASS_$_UIView U ___CFConstantStringClassReference U ___addsf3vfp U ___divdf3vfp U ___divsf3vfp U ___extendsfdf2vfp U ___muldf3vfp U ___truncdfsf2vfp U _objc_enumerationMutation U _objc_msgSend U _objc_msgSend_stret U dyld_stub_binding_helper

• The best way to build iPhone/iPad static libraries?

  - by Derek Clarkson

  Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

• Why do i get E_ACCESSDENIED when reading public shortcuts through Shell32?

  - by corvuscorax

  I'm trying to read the targets of all desktop shortcuts in a C# 4 application. The shortcuts on a windows desktop can come from more that one location, depending on whether the shortcut is created for all users or just the current user. In this specific case I'm trying to read a shortcut from the public desktop, e.g. from C:\Users\Public\Desktop\shortcut.lnk. The code is like this (path is a string contaning the path to the lnk file): var shell = new Shell32.ShellClass(); var folder = shell.NameSpace(Path.GetDirectoryName(path)); var folderItem = folder.ParseName(Path.GetFileName(path)); if (folderItem != null) { var link = (Shell32.ShellLinkObject)folderItem.GetLink; The last line throws an System.UnauthorizedAccessException, indicating that it's not allowed to read the shortcut file's contents. I have tried on shortcut files on the user's private desktop (c:\Users\username\Desktop) and that works fine. So, my questions are: (1) why is my application not allowed to /read/ the shortcut from code, when I can clearly read the contents as a user? (2) is there a way to get around this? Maybe using a special manifest file for the application? And, by the way, my OS is Windows 7, 64-bit. be well -h-

• Difficulty with projectile's tracking code

  - by RCIX

  I wrote some code for a projectile class in my game that makes it track targets if it can: if (_target != null && !_target.IsDead) { Vector2 currentDirectionVector = this.Body.LinearVelocity; currentDirectionVector.Normalize(); float currentDirection = (float)Math.Atan2(currentDirectionVector.Y, currentDirectionVector.X); Vector2 targetDirectionVector = this._target.Position - this.Position; targetDirectionVector.Normalize(); float targetDirection = (float)Math.Atan2(targetDirectionVector.Y, targetDirectionVector.X); float targetDirectionDelta = targetDirection - currentDirection; if (MathFunctions.IsInRange(targetDirectionDelta, -(Info.TrackingRate * deltaTime), Info.TrackingRate * deltaTime)) { Body.LinearVelocity = targetDirectionVector * Info.FiringVelocity; } else if (targetDirectionDelta > 0) { float newDirection = currentDirection + Info.TrackingRate * deltaTime; Body.LinearVelocity = new Vector2( (float)Math.Cos(newDirection), (float)Math.Sin(newDirection)) * Info.FiringVelocity; } else if (targetDirectionDelta < 0) { float newDirection = currentDirection - Info.TrackingRate * deltaTime; Body.LinearVelocity = new Vector2( (float)Math.Cos(newDirection), (float)Math.Sin(newDirection)) * Info.FiringVelocity; } } This works sometimes, but depending on the relative angle to the target projectiles turn away from the target instead. I'm stumped; can someone point out the flaw in my code?

• Powershell invoke-command with PSCredential in line

  - by jaffa

  I need to be able to run a command on another server. This script acts as a bootstrap to another script which is run on the actual server. This works great on servers on the same domain, but if I need to run this script on a remote server, I need to specify credentials. The command is kicked off from a Msbuild targets file like so: <Target Name="PreDeployment" Condition="true" BeforeTargets="MSDeployPublish"> <Exec Command="powershell.exe -ExecutionPolicy Bypass invoke-command bootstrapScript.ps1 -computername $(MyServer) -argumentlist param1, param2" /> </Target> However, I need to be able to supply the credentials by creating a new PSCredentials object with a secure password for my deployment script to run on a remote server: <Target Name="PreDeployment" Condition="true" BeforeTargets="MSDeployPublish"> <Exec Command="powershell.exe -ExecutionPolicy Bypass invoke-command bootstrapScript.ps1 -computername $(MyServer) -credential New-Object System.Management.Automation.PSCredential ('admin', (convertto-securestring $(Password) -asplaintext -force)) -argumentlist param1, param2" /> </Target> When I run the build, a dialog pops up with the username set to System.Management.Automation.PSCredential. I need to be able to create the credentials in-line on the executable target. How do I accomplish this?

• How to parameterize a path in ANT?

  - by strelokstrelok

  I have the following defined in a file called build-dependencies.xml <?xml version="1.0" encoding="UTF-8"?> <project name="build-dependencies"> ... <path id="common-jars"> <fileset file="artifacts/project-1/jar/some*.jar" /> <fileset file="artifacts/project-2/jar/someother*.jar" /> </path> ... </project> I include it at the top of my build.xml file. Now I need to make the artifacts folder a parameter so it can be changed during execution of different targets. Having this... <?xml version="1.0" encoding="UTF-8"?> <project name="build-dependencies"> ... <path id="common-jars"> <fileset file="${artifacts}/project-1/jar/some*.jar" /> <fileset file="${artifacts}/project-2/jar/someother*.jar" /> </path> ... </project> ...and defining an "artifacts" property (and changing it) in the target does not work because it seems that the property substitution happens when the path is defined in build-dependencies.xml How can I solve this? One way I was thinking was to have a parameterized macro and call that before the path is actually used, but that seems not elegant. Something like this: <macrodef name="create-common-jars"> <attribute name="artifacts"/> <sequential> <path id="common-jars"> <fileset file="@{artifacts}/project-1/jar/some*.jar" /> <fileset file="@{artifacts}/project-2/jar/someother*.jar" /> </path> </sequential> </macrodef>

• Make Ant's delete task fail when a directory exists and is not deleted but not when it doesn't exist

  - by Tim Visher

  I have tho following clean function in my build script and I'd like to know how I can improve it. <target name="clean" description="Clean output directories."> <!-- Must not fail on error because it fails if directories don't exist. Is there really no better way to do this? --> <delete includeEmptyDirs="true" failonerror="false"> <fileset dir="${main.build.directory}" /> <fileset dir="dist" /> <fileset dir="${documentation.build.directory}" /> <fileset dir="/build-testing" /> </delete> </target> Specifically regarding my comment, I'm unhappy with the fact that I can't run this on a fresh box because the directory structure hasn't been set up yet by the other targets. We run the build in such a way that it entirely recreates the structures necessary for testing and deployment every time to avoid stale class files and such. With the way that delete currently is set up, a failure to delete a file does not fail the build and I'd like it to. I don't want it to fail the build if the file doesn't exist though. If it doesn't exist then what I'm asking it to do has already happened. Thoughts?

• Adding a new target type to msbuild: How do I refer to the itemname in the task rules?

  - by jmucchiello

  I'm trying to add a task to build the COM proxy DLL after building the main DLL. So I created the following in a .target file: <Target Name="ProxyDLL" Inputs="$(IntDir)%(WHATGOESHERE)_i.c;$(IntDir)dlldata.c" Outputs="$(OutDir)%(WHATGOESHERE)ps.dll" AfterTargets="Link"> <CL Sources="$(IntDir)%(WHATGOESHERE)_i.c;$(IntDir)dlldata.c" /> </Target> And reference it from the .vcxproj file as <ItemGroup> <ProxyDLL Include="FTAccountant" /> </ItemGroup> So the FTAccountant.DLL file is created through the normal build process and then when attempts to compile the proxy stubs it creates these command lines: cl /c dir\_i.c dir\dlldata.c And of course it can't find _i.c. The first attempt, I put %(Filename) in the WHATGOESHERE space and I got this error: C:\ActivePay\Build\Proxy DLL.targets(6,3): error MSB4095: The item metadata %(Filename) is being referenced without an item name. Specify the item name by using %(itemname.Filename). So I changed it to %(itemname.Filename) and that is an empty string. How to get the value specified in the task's Include attribute and use it within the task?

• Setting processor affinity on CSC.exe launched by CoreCompile MSBuild Task

  - by Hardy

  I am wondering if there is simple way to ensure that when a c# project is compiled the CSC.exe launched inherits the parent processor affinity settings, or perhaps of a way where by i can supply this. I have been trying to accomplish this by launching a bat file from vs.net cmd prompt like start /affinity 01 custombuild.cmd and inside my custombuild.cmd i have @echo off msbuild Libraries.sln /t:rebuild /p:Configuration=Release;platform=x64 /m:1 :END The command line call to Csc.exe this generates looks like the following C:\Windows\Microsoft.NET\Framework\v4.0.30319\Csc.exe ... ignoring the rest for brevity. What i 'd like to see is the CSC.exe to inherit the processor affinity or a simple way to be able to override how csc.exe call is generated so i can make it into a start /affinity 01 C:\Windows\Microsoft.NET\Framework\v4.0.30319\Csc.exe ... ignoring the rest for brevity. I also noticed that CoreCompile target is defined in Microsoft.CSharp.targets, should i be considering overriding MSBuildToolsPath variable so i can sneak in my own version. This feels rather hacky. Any help would be much appreciated.

• Strategy for locale sensitive sort with pagination

  - by Thom Birkeland

  Hi, I work on an application that is deployed on the web. Part of the app is search functions where the result is presented in a sorted list. The application targets users in several countries using different locales (= sorting rules). I need to find a solution for sorting correctly for all users. I currently sort with ORDER BY in my SQL query, so the sorting is done according to the locale (or LC_LOCATE) set for the database. These rules are incorrect for those users with a locale different than the one set for the database. Also, to further complicate the issue, I use pagination in the application, so when I query the database I ask for rows 1 - 15, 16 - 30, etc. depending on the page I need. However, since the sorting is wrong, each page contains entries that are incorrectly sorted. In a worst case scenario, the entire result set for a given page could be out of order, depending on the locale/sorting rules of the current user. If I were to sort in (server side) code, I need to retrieve all rows from the database and then sort. This results in a tremendous performance hit given the amount of data. Thus I would like to avoid this. Does anyone have a strategy (or even technical solution) for attacking this problem that will result in correctly sorted lists without having to take the performance hit of loading all data? Tech details: The database is PostgreSQL 8.3, the application an EJB3 app using EJB QL for data query, running on JBoss 4.5.

• Does anchor href of an image make it download?

  - by matthewsteiner

  So I was using yslow for firefox and my page weight was way high. My page has a main product image and then maybe 10 thumbnails. If you click a thumbnail, the image opens up in a popup done through jquery. The problem is, yslow is listing even the targets of the thumbnails as part of the page weight, so I guess for some reason the images are downloading. For example, I have: <a class="group nyroModal" rel="lightbox-group" href="/upload/topview.jpg"> <img alt="thumbnail" src="/upload/thumb/t_topview.jpg" /> </a> Would this normal html cause the "upload/topview.jpg" to automatically download? Or is it the jquery plugin "nyroModal"? I'd rather the images didn't preload, that'd waste a lot of bandwidth. So my question is, does a browser automatically try to download image files that are in the href property of anchors, or is the plugin most likely causing this? Thanks for any direction you can give me.

• Target module with custom layout in Magento

  - by dardub

  In my custom module, I'd like to include an extra block and style sheet that targets only pages within my custom module. So that when i access myserver.com/configurator/ Pages will use the correct template I specified In the catalog.xml file, I noticed <catalog_category_default> That seems to be what I am looking for, so I tried: <configurator_default_default> <reference name="root"> <action method="setTemplate"><template>configurator/2columns-right.phtml</template></action> </reference> <reference name="head"> <action method="addCss"><stylesheet>css/configurator.css</stylesheet></action> </reference> <reference name="content"> <block type="configurator/guide" name="timeline" template="configurator/guide/timeline.phtml" /> </reference> </configurator_default_default> But it doesn't change the template for pages within the module. I also tried <configurator_guide_default> But it doesn't pick up the correct template If i put it within the specific page such as <configurator_guide_page1> Then it works.

• VS2010 Web Deploy: how to remove absolute paths and automate setAcl?

  - by Julien Lebosquain

  The integrated Web Deployment in Visual Studio 2010 is pretty nice. It can create a package ready to be deployed using MSDeploy on a target IIS machine. Problem is, this package will be redistributed to a client that will install it himself using the "Import Application" from IIS when MSDeploy is installed. The default package created always include the full path from the development machine, "D:\Dev\XXX\obj\Debug\Package\PackageTmp" in the source manifest file. It doesn't prevent installation of course since it was designed this way, but it looks ugly in the import dialog and has no meaning to the client. Worse he will wonder what are those paths and it looks quite confusing. By customizing the .csproj file (by adding MSBuild properties used by the package creation task), I managed to add additional parameters to the package. However, I spent most of the afternoon in the 2600 lines long Web.Publishing.targets trying to understand what parameter influenced the "development path" behavior, in vain. I also tried to use the setAcl to customize security on a given folder after deployment, but I only managed to do this with MSBuild by using a relative path... it shouldn't matter if I resolve the first problem though. I could modify the generated archive after its creation but I would prefer if everything was automatized using MSBuild. Does anyone know how to do that?

• using a 64-bit compiler in microsoft visual c++

  - by Ben

  this question is essentially identical to an earlier question i had that didn't receive any answers. hopefully someone can help me out this time. i am trying to compile a vc++ project as 64 bit using visual c++ express 2010. i know that the 64 bit compiler does not come with the default installation of vc++ express so i installed windows sdk for windows 7 as specified here (http://msdn.microsoft.com/en-us/library/9yb4317s.aspx) which includes the 64 bit compiler as i understand. however, there is still no 64 bit option in the configuration manager for vc++. after some searching i found and completed this tutorial (http://jenshuebel.wordpress.com/2009/02/12/visual-c-2008-express-edition-and-64-bit-targets/) as well as the various links at the bottom of this page. despite all my efforts, i still cannot get the 64 bit compiler to show in vc++ (i.e. the 64 bit compiler won't show under "active solutions platform" in the configuration manager). if anyone has any experience/tips with getting this to work i would really appreciate it. fyi - i am running windows 7(x64).

• Setting CPU target to x86 on .NET 2.0 project adds .NET 3.5 dependencies.

  - by AngryHacker

  I have a project in VS2008 that targets .NET 2.0 framework. It was original set to build for AnyCPU. I changed it to x86 and for whatever reason, VS adds the following lines to .csproj: <ItemGroup> <BootstrapperPackage Include="Microsoft.Net.Client.3.5"> <Visible>False</Visible> <ProductName>.NET Framework Client Profile</ProductName> <Install>false</Install> </BootstrapperPackage> ... ... <BootstrapperPackage Include="Microsoft.Net.Framework.3.5.SP1"> <Visible>False</Visible> <ProductName>.NET Framework 3.5 SP1</ProductName> <Install>false</Install> </BootstrapperPackage> </ItemGroup> Can someone explain as to why this is being added and whether I can safely remove it, as I still have to target the .NET 2.0 framework. Thanks.

• jQuery arrays - newbie needs a kick start

  - by Jonny Wood

  I've only really started using this site and alredy I am very impressed by the community here! This is my third question in less than three days. Hopefully I'll be able to start answering questions soon instead of just asking them! I'm fairly new to jQuery and can't find a decent tutorial on Arrays. I'd like to be able to create an array that targets several ID's on my page and performs the same effect for each. For example I have tabs set up with the following: $('.tabs div.tab').hide(); $('.tabs div:first').show(); $('.tabs ul li:first a').addClass('current'); $('.tabs ul li a').click(function(){ $('.tabs ul li a').removeClass('current'); $(this).addClass('current'); var currentTab = $(this).attr('href'); $('.tabs div.tab').hide(); $(currentTab).show(); return false; }); I've used the class .tag to target the tabs as there are several sets on the same page, but I've heard jQuery works much faster when targetting ID's How would I add an array to the above code to target 4 different ID's? I've looked at var myArray = new Array('#id1', 'id2', 'id3', 'id4'); And also var myValues = [ '#id1', 'id2', 'id3', 'id4' ]; Which is correct and how do I then use the array in the code for my tabs...?

• Mulltiple configurations in Qt

  - by user360607

  Hi all! I'm new to Qt Creator and I have several questions regarding multiple build configurations. A side note: I have the QtCreator 1.3.1 installed on my Linux machine. I need to have two configurations in my Qt Creator project. The thing is that these aren't simply debug and release but are based on the target architecture - x86 or x64. I came across http://stackoverflow.com/questions/2259192/building-multiple-targets-in-qt-qmake and from that I went trying something like: Conf_x86 { TARGET = MyApp_x86 } Conf_x64 { TARGET = MyApp_x64 } This way however I don't seems to be able to use the Qt Creator IDE to build each of these separately (Build All, Rebuild All, etc. options from the IDE menu). Is there a way to achieve this - may be even show Conf_x86 and Conf_x64 as new build configurations in Qt Creator? One other thing the Qt I have is 64 bit so by default the target built using Qt Creator IDE will also be 64 bit. I noticed that the effective qmake call in the build step includes the following option '-spec linux-g++-64'. I also noticed that should I add '-spec linux-g++-32' in 'Additional arguments' it would override '-spec linux-g++-64' and the resulting target will be 32 bit. How can I achieve this by simply editing the contents of the .pro file? I saw that all these changes are initially saved in the .pro.user file but does doesn't suit me at all. I need to be able to make these configurations from the .pro file if possible. Any help will be appreciated. 10x in advance!

• Can't find momd file: Core Data problems

  - by thekevinscott

  Aw geez! I screwed something up! I'm a Core Data noob, working on my first iOS app. After much Stack Overflowing I'm using this code: NSString *path = [[NSBundle mainBundle] pathForResource:@"CoreData" ofType:@"momd"]; if (!path) { path = [[NSBundle mainBundle] pathForResource:@"CoreData" ofType:@"mom"]; } NSAssert(path != nil, @"Unable to find Resource in main bundle"); CoreData is the name of my app. I've tried to put in initial data into the app by finding the path to the sqlite file in my iPhone simulator, and then going and inserting into that sqlite file. But at some point, I moved the sqlite (thinking it would create a fresh copy), deleted the app from the simulator, and the sqlite file is gone. I'm not sure if I'm leaving out some part of the process (this was a few hours ago) but the end result is that everything is screwed up. How do I resubstantiate this sqlite / momd file? "Clean" and "Clean all targets" are grayed out. I'm happy to post the relevant code from my app that would help shed some light on this problem but there's tons of code relating to Core Data which I don't understand, so I'm not sure what part to post! Any help is greatly appreciated.

• What's the proper approach for writing multi-path "story" flows?

  - by Basiclife

  Hi, I wonder if you can help me. I'm writing a game (2d) which allows players to take multiple routes, some of which branch/merge - perhaps even loop. Each section of the game will decide which section is loaded next. I'm calling each section an IStoryElement - And I'm wondering how best to link these elements up in a way that is easily changed/configured and at the same time, graphable I'm going to have an engine/factory assembly which will load the appropriate StoryElement(s) based on various config options. I initially planned to give each StoryElement a NextElement() As IStoryElement property and a Completed() event. When the vent fires, the engine reads the NextElement property to find the next StoryElement. The downside to this is that if I ever wanted to graph all the routes through the game, I would be unable to - I couldn't determine all possible targets for each StoryElement. I considered a couple of other solutions but they all feel a little clunky - eg Do I need an additional layer of abstraction? ie StoryElementPlayers or similar - Each one would be responsible for stringing together multiple StoryElement perhaps a Series and a ChoicePlayer with each responsible for graphing its own StoryElement - But this will just move the problem up a layer. In short, I need some way of emulating a simple but dynamic workflow (but I'd rather not actually use WWF). Is there a pattern for something this simple? All the ones I've managed to find relate to more advanced control flow (parallel processing, etc.)

• What /else/ causes this?

  - by Mordachai

  MFC Toolbox Library.lib(SimpleFileIO.obj) : error LNK2005: _wcsnlen already defined in libcmtd.lib(wcslen_s.obj) fatal error LNK1169: one or more multiply defined symbols found This is driving me nuts. Normally, one would get this if the various projects that are a part of their solution do not agree on which CRT to use (single threaded, multi-threaded, release or debug). However, I have been over this thing about 500 times now, and they all agree. Background: this is a VS 2010 project just converted from VS 2008. MFC Toolbox Library.lib is set to compile as a static library, using /MTd, as is the target .exe I am trying to compile in this solution. Further, the solution that this is being converted from (VS 2008) already compiles & links properly!!! So it's not like that there is a disagreement between the two .vcproj's - or at least there wasn't before the conversion. Furthermore, the MFC Toolbox Library is used by about 25 other projects in another solution - and in that solution (Master Build English) it compiles & links against those other projects without complaint in both debug and release targets. I have just spent the last hour going over every single project property for this target project (Cimex Header Viewer) vs. several different target exe projects in Master Build English solution - and I cannot find a difference. They appear to be identical, excepting that they're different names. I've tried doing a clean & build all. I'm simply out of ideas. Does anyone have a thought on what else I might investigate??? I think I'm ready to start chewing glass. :(

• Could not launch console app with xCode 4.4

  - by lp1756

  I have a project with two targets -- an iOS app and an OSX console app. The latter was created using Xcode File-New Target and selecting "Command Line Tool". This console app is used to prep a default database needed by the iOS app -- using CoreData. This has been working fine until I upgraded to Mountain Lion and xCode 4.4. Now when I try to run the command line tool I get a "Could Not Launch -- permission denied" error. I have tried playing around with signing certificates, to no avail. Interestingly if I create a new "hello, world" command line tool in a new project it works just fine -- and it is not signed at all. I checked the file and it has -rwxr-xr-x permission. In the debugger the app fails on startup even before it tries to access the moms. If I try to run this outside of the debugger at the command line, it ends with a kill 9 message. Any ideas would be greatly appreciated.

• Android: Adding header to dynamic listView

  - by cg5572

  I'm still pretty new to android coding, and trying to figure things out. I'm creating a listview dynamically as shown below (and then disabling items dynamically also) - you'll notice that there's no xml file for the activity itself, just for the listitem. What I'd like to do is add a static header to the page. Could someone explain to me how I can modify the code below to EITHER add this programatically within the java file, before the listView, OR edit the code below so that it targets a listView within an xml file! Help would be much appreciated!!! public class Start extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); DataBaseHelper myDbHelper = new DataBaseHelper(null); myDbHelper = new DataBaseHelper(this); try { myDbHelper.openDataBase(); }catch(SQLException sqle){ throw sqle; } ArrayList<String> categoryList = new ArrayList<String>(); Cursor cur = myDbHelper.getAllCategories(); cur.moveToFirst(); while (cur.isAfterLast() == false) { if (!categoryList.contains(cur.getString(1))) { categoryList.add(cur.getString(1)); } cur.moveToNext(); } cur.close(); Collections.sort(categoryList); setListAdapter(new ArrayAdapter<String>(this, R.layout.listitem, categoryList) { @Override public View getView(int position, View convertView, ViewGroup parent) { View view = super.getView(position, convertView, parent); if(Arrays.asList(checkArray3).contains(String.valueOf(position))){ view.setEnabled(false); } else { view.setEnabled(true); } return view; } }); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { if(v.isEnabled()) { String clickedCat = l.getItemAtPosition(position).toString(); Toast.makeText(this, clickedCat, Toast.LENGTH_SHORT).show(); finish(); Intent myIntent = new Intent(getApplicationContext(), Questions.class); myIntent.putExtra("passedCategory", clickedCat); myIntent.putExtra("startTrigger", "go"); startActivity(myIntent); } } }

• How would I include open source library in my iPhone application?

  - by greypoint

  I have found an existing open source library that I would like to include in my iPhone project (the unrar source code found here: http://www.rarlab.com/rar_add.htm ). I have compiled this source as a linked library on my Mac with "make lib" which creates the libunrar.so file just fine. These are the makefile settings for that target: lib: WHAT=RARDLL lib: $(OBJECTS) $(LIB_OBJ) @rm -f libunrar.so $(LINK) -shared -o libunrar.so $(LDFLAGS) $(OBJECTS) $(LIB_OBJ) Obviously I can't use this on iPhone but I imagine I should be able to compile with different options to make a static library that I can use. Do I: Compile it on the Mac with different make options then drag the resulting library (some kind of .a ?) into my xcode project? or Drag all of the source code into my xcode project and create special targets of some kind to create it? or Something else entirely different? I've been working on solving my unrar problem for a couple of weeks now and I believe using this library will give me the best results but I just don't know the final steps to make use of it. Thanks for all advice.

• css absolute positioning hidden scrollbars ... with a twist

  - by ScottE

  I'm working on a website that targets 1024 X 768 as the minimum resolution. So, we're at about 970px wide. Design came back with an interesting layout that has a centered site with a banner that actually exceeds this width (1288px to be exact) that will look good for users with greater resolution, but look fine at 1024. So, to prevent scrollbars from showing up for those at 1024 I positioned the banner absolutely and used overflow-x: hidden on the body. This works just fine across our target browsers. Now, the client has come back and asked for scrollbars to be present for users on 800 X 600 (yes, this is not the target) so they can see a critical login button. How can this be accommodated for those 2% of their users without making radical changes? All I can think of is to detect their screen width and remove the overflow-x:hidden. You have to love when requirements change late in the build process! Edit - here's what I have that seems simple enough to me - any caveats here? if (screen.width === 800) { $("body").css("overflow-x", "visible"); }
