• Android: How to maintain backwards-compatibility?

  - by Peterdk

  According to the instructions found here, to make your app state which screen sizes you can support, you'll need to compile your app against Android 1.6. Using the minSdkVersion and targetSdkVersion this should run also on Android 1.5: <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/> However, when I try to launch my app from Eclipse to run in a emulated 1.5, I get the following error: Failed to find an AVD compatible with target 'Android 1.6'. Is this an error of the eclipse tools/emulator? Or how do I get it to also target 1.5 correctly while giving me the option to specify the supported screens?

• Iphone UIView implementation

  - by Joo Park

  How does one code this scenerio in iphone sdk? In an expense app, when you want to add an expense, this view comes up. After selecting "Clothing," another view slides up with a UIPickerView control that has a "done" button which will dismiss the UIPickerView. Below is a screen shot after hitting "Clothing." I'm trying to figure out how one would slide up the UIPickerView half way up the screen with a "done" button on top of the "New Expense" view? thank you in advance!

• Get Hardware Information for HWs that is not installed

  - by Isaac

  I am pretty sure how to retrieve hardware information with WMI classes. but WMIs have a big limitation: They Just can get information for installed hardwares. I need to retrieve information about CPU (model,speed,etc..),Video Card, Sound Card, USB Ports, etc. I found a really good software (HWiNFO) that can do this even the drivers for hardware parts is not installed. It seems that HWiNFO uses a internal database to give a name for each hardware part. So is there any free library/DLL/component that can do this in Windows XP or higher Note: Although HWiNFO SDK seems good, it's not free. So it doesn't exist! ;) I need a free library.

• Facebook Connect in Iphone header include path.

  - by nishantcm

  Hi, I am trying to compile facebook library for my iphone application. But I am getting this error. error: FBConnect/FBConnect.h: No such file or directory I have added the location of the folder in header search paths and yet it is not compiling. This is the path that I have added- /Users/nishant/Downloads/facebook-facebook-iphone-sdk-1059eb6/src. I even tried the copy files to destination folder option, but that also did not work. I know this is a very simple step, but I am getting frustrated, because I have tried this like 20-30 times. Any help.

• Android AlertDialog with dynamically changing text on every request

  - by Ulrich Scheller

  I want to show an AlertDialog with one option that might change on every request. So for example at one time I want to show the option "add to contacts" while another time it should be "remove from contacts". My code does work on the first time, however Android seems to cache the AlertDialog so that onCreateDialog is not executed next time. Therefore the option doesnt change anymore. Can I prevent this caching, or is there just another way of changing the option? I am working with SDK 1.5 but using 1.1. @Override protected Dialog onCreateDialog(final int id) { ... String add_remove_contact = res.getString(R.string.profile_add_to_contacts); if (user.getContacts().contains(profileID)) { add_remove_contact = res.getString(R.string.profile_remove_from_contacts); // TODO: this string is not changed when contact status changes } final CharSequence[] items = {res.getString(R.string.view_profile), res.getString(R.string.profile_send_message), add_remove_contact}; AlertDialog.Builder builder = new AlertDialog.Builder(this); ... return builder.create(); }

• Using code in both Actionscript3 and Javascript

  - by Ian

  Here's an interesting architectural query. I have a piece of code that needs to run on the server (under Node.js) and on the client (in a Flash 10 app written with Actionscript 3). The code is mostly fairly intricate object manipulation, it doesn't make any API calls, and works fine in both contexts. So far the project is just a demo, so I've been happy to copy and paste the code into both places. But it might be quite interesting to move forward with this. So how would you do it? I assume there is no easy way to get the Flash SDK (has to build without an IDE) to read and do something useful with a .js file. My only thought is that I could write a code-generator that takes the .js file and places it in an ActionScript wrapper. Are there any obvious approaches that I've missed? Just to pre-empt an obvious answer, I know about cross-platform languages like HaXe.

• Using makecert for Development SSL

  - by John

  Here's my situation: I'm trying to create a SSL certificate that will be installed on all developer's machine's, along with two internal servers (everything is non-production). What do I need to do to create a certificate that can be installed in all of these places? Right now I've got something along these lines, using the makecert application in Microsoft Visual Studio 8\SDK\v2.0\Bin: makecert -r -pe -n "CN=MySite.com Dev" -b 01/01/2000 -e 01/01/2033 -eku 1.3.6.1.5.5.7.3.1 -ss Root -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 mycert.cer However, I'm not sure as to how to place this .cer file on the other computers, and when I install it on my local machine IIS, everytime I visit a page via https:, I get the security prompt (even after I've installed the certificate). Has anyone done this before?

• Change Titlewindow close button

  - by Cameigons

  I'm working with Flex 3.4 SDK. I need to change the default close button image from a TitleWindow. So what I'm doing is defining a CSS selector, like this: TitleWindow{ close-button-skin: Embed('assets/close.png'); border-color: #FFFFFF; corner-radius: 10; closeButtonDisabledSkin: ClassReference(null); closeButtonDownSkin: ClassReference(null); closeButtonOverSkin: ClassReference(null); closeButtonUpSkin: ClassReference(null); } The problem is: the result image is totally squeezed beyond recognition. Probably because the image dimensions are 55x10 pixels (much wider than the default closebutton square-like dimensions) and flex forces it to fit that size. Would anyone know how to go about fixing that?

• OpenGL ES canvas size

  - by Chaoz

  Ahoy, I'm working on an OpenGL ES based game for Android using the NDK. My application is targeted towards SDK 1.6 and above. I seem to be having a problem creating a canvas of the phones native size. My rendering is done through a native gameloop that uses OpenGL 1.0. I'm using the emulator and that gives me a 480x320 canvas -- this is totally fine. Then, when I run the same application on my HTC Desire which has a native resolution of 800x480 I'm getting a canvas of 533x320. Anyone have any information on how to deal with/solve this? Any other information about this is also appreciated. Thanks in advance!

• Dynamics CRM Get Info For Customer

  - by macinjosh

  I'm working on a ASP.NET (C#) site that pulls most of its data from Dynamics CRM over SOAP using Microsoft's CrmService SDK. I'm at the point where a query has returned an entity with a property of the type Customer. I need to get the name string of that customer record, but cannot figure out how to do so. By doing a little guess work I figured out that what I have is GUID for the customer. How can I use this GUID to get the customer's name as a string?

• Android and config.xml

  - by synic

  Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

• Proper way in MVVM to drive visual states.

  - by firoso

  Given a content presenter that can display one of 4 different application pages, and I want to fade/otherwise animate a transition between pages based on view model state. Ideally I'd like to have these all defined within a DataTemplate, and then trigger transitions based on an enum from the view model, so that when some enum representing state changes, the transitions trigger to the appropriate page. Is there a known best practice to handle things like this? Immediately coming to mind is the possibiltiy to use Enter and Exit actions on data triggers to play storyboards, but this definately doesn't use the parts and states model, so I'd like to shy away from that. I've also tried using the DataStateSwitchBehavior from the codeplex Expression project, but found it to be incompatable with the latest builds of WPF 4.0/Blend 4 RC's SDK. Does anyone have any ideas on how to handle this elegantly? I'm using the MVVM-Light framework. Also I'd like to point out that as long as this resides on a DataTemplate in a Resource Dictionary, code-behind is not an option without refactoring.

• Problem deploying GWT project with a servlet that invoke an EJB

  - by bovo

  I have a simple GWT project in Eclipse, it has a servlet that calls an EJB and everything works fine when I run it in hosted mode from Eclipse. MyProject +- src +- JRE System Library +- GWT SDK +- Apache Geronimo v2.2 +- myEJB.jar +- openejb.jar -- war -- +- images -- +- myproject -- +- WEB-INF I'm not sure what is the best way to deploy it, but what I did is create a .war file from the "war" folder of the project then deploy it to the server. Communication between client and server works fine but I get an error when I try to do JNDI look up for the EJB within the servlet. The error I get is something like "JNDI error, cannot find FooManagerRemote" Things works fine in hosted mode so I'm pretty sure that I din't deploy it correctly.

• Developing Silverlight 1.0 Applications on VS2008 SP1

  - by Moo

  Hi, Can anyone point me to any guides, howto's or general documentation on how to develop Silverlight 1.0 (it has to be 1.0) on VS2008 SP1. I have searched high and low for information, and it all seems to be out of date (referencing Silverlight 1.0 Tools for Visual Studio 2008 beta, release candidate and alpha packages) or just plain doesn't work under VS2008 SP1. What do I need to install, and which project do I need to create? I have installed the Silverlight 1.0 SDK, which gave me no starting point, the Silverlight 2.0 Tools for Visual Studio after a website suggested you could use that to develop 1.0 apps, but the suggested template doesn't exist, and Silverlight 3.0 Tools for Visual Studio, which was a last ditch resort. Regards Moo

• Writing Facebook apps in C#

  - by Water Cooler v2

  Hi, I am a C# developer and fancy the idea of writing a C# app or two to integrate with the Facebook API. I read from this page: http://wiki.developers.facebook.com/index.php/User:C_Sharp that there's this Microsoft SDK for Facebook Platform that has binary assemblies that I can use to write my C# app. As a start, I want to try out the example mentioned on the above-mentioned page -- one that gets me a friend list. The problem is: I am completely new to this Facebook development thing and I see I am going to need, at the very least, an API Key and some Facebook service Secret key or some such, to begin writing some code. Do I also need a developer account? Where do I get all these things from?

• How do you read system jobs in Dynamics CRM?

  - by Dan Crowther

  The CRM SDK says this is possible but the following code fails. Does anyone know why? var request = new RetrieveMultipleRequest(); var query = new QueryExpression(EntityName.asyncoperation.ToString()); query.ColumnSet = new AllColumns(); request.Query = query; var response = _connection.Execute(request); The error is: <error>\n <code>0x80040216</code> <description>An unexpected error occurred.</description> <type>Platform</type> </error> If I change the entity name to account, it works fine.

• -sizeWithFont Functions Differently on Device

  - by LucasTizma

  So I am seemingly encountering some strange behavior when using NSString's -sizeWithFont family of method calls depending on whether or not I'm invoking it on the iPhone Simulator or an actual device. Simply enough, when the receiver of the -sizeWithFont method call is nil, the resulting CGSize passed back on the Simulator is {0, 0}. However, on the device, it is the size of the bounding rectangle I specified in the method call. See the following log statements: Simulator: someString: (null) someStringSize: {0, 0} Device: someString: (null) someStringSize: {185, 3.40282e+38} The behavior on the Simulator is what I would expect. Not that this issue is difficult to circumvent, but 1) I'm a little confused why this family of functions would behave differently on the Simulator and an actual device, and 2) why does calling a method on a nil receiving return a particular result? Thanks for any pointers or insight you guys can provide! EDIT: I suppose I should mention that I'm building against the 3.1 SDK.

• GKPeerStateAvailable for non existing peers?

  - by Ernest

  Hi, used this website for the long time to find answers, now need to ask on myself! :) I have implemented multi player for my game using GKSession and client/server approach, not using peer picker (up to 4 player allowed). I have one big problem which I can't find solution for. If you disconnect/reconnect server peer quickly enough, client peer will "remember" that host and will show it in the list of all available peers permanently, only turning wifi/bluetooth off resets this. So if I do this 5 times in a row, my client will show 5 available hosts with the same name! Anyone had experience with this? Any idea of workarounds? I should note that requirements for my game is iPhone SDK 3.0 for Bluetooth and 3.1 for Wifi as GKSession supports both now.

• MySql UDF using shared library won't load

  - by Jarrod

  I am attempting to create a mysql UDF which will match a fingerprint using Digital Persona's free linux SDK library. I have written a trivial UDF as a learning experience which worked fine. However, when I added a dependency to Digital Persona's shared object I can no longer get MySql to load my UDF. I added includes to DP's headers and compiled my UDF using: gcc -fPIC -Wall -I/usr/src/mysql-5.0.45-linux-i686-icc-glibc23/include -shared -o dp_udf.so dp_udf.cc I also tried adding the -static argument, but whenever I restart MySql, I get the error: Can't open shared library 'dp_udf.so' (errno: 0 /usr/local/mysql/lib/plugin/dp_udf.so: undefined symbol: MC_verifyFeaturesEx) MC_verifyFeaturesEx is a function defined "dpMatch.h" which I included, and is implemented in libdpfpapi.so which I have tried placing in the same location as my dp_udf.so and in /usr/lib. Am I doing something wrong with my call to gcc (my C++ skills are rusty) or does MySql not allow UDFs to use additional shared objects?

• Embedding an existing exe file into another program

  - by Milad

  Is there a way to link an existing .exe file with other C++ source files during compilation? What I'm actually trying to do is to compress and decompress some files in my console program using LZMA(7zip) SDK but unfortunately it's very difficult to use for a newbie. There is a command line version of LZMA called 7za.exe and I am wondering if I can somehow embed it into my program and use it like a function. It can be easily used with system() function (which seems to be a very dangerous thing to use) but then if I send my program to someone who doesn't have 7za.exe in the right folder it won't work. I came across CreateProcess() function in windows.h header files but it seems to achieve what system() does in a more proper and advanced way. I don't know if it can actually link the exe file like an object file during compilation

• Adobe Livecycle performance

  - by Fabio

  I have installed Adobe Livecycle in order to convert MSWORD files to PDF from a web-app. Specifically, I use the DocConverter tool. Previously I have used OpenOffice UNO SDK, but I have found some problems with particular documents. Now, the conversion is ok, but the conversion time is huge. These are the times to convert documents of different sizes via Openoffice and via Livecycle. Could you suggest anything?
