• How to start develop for chinese mobile phones based on nucleus RTOS? (MTK)

  - by juckobee

  I've noticed that chinese mobile phones became very popular, perhaps because of their very reasonable price and many modern features (touch screens, advanced multimedia, double sim cards etc). I'm wondering if there's any way to develop custom solutions for this handsets as independent developer? How to obtain a toolkit and documentation? I've found some resources, but mainly inconsistent tech notes, often in chinese only. For now I know, that majority of chinese handsets are based on chips from MediaTek (MTK), with operating system based on Nucleus RTOS and MMI (plutoMMI?) framework. Unfortunately, there is no Java RE avaiable (ok, there are some handsets with Java, however, Java isn't something I'm looking for) Is there any SDK, documentation, emulators/simulators, how-tos, etc avaiable? How to develop, deploy and test custom application for MTK mobile?

• EMail Signing (Outlook) Using Smartcard Minidriver [Windows]

  - by Baget

  Hi I'm developing a Smart card Minidriver and I'm trying to Sign an Email using Outlook 2007. I have implemented all of the necessary functions in the minidriver. I'm able to create a "Smartcard User" certificate and save it and it's private key on the smartcard (using Microsoft Certificate Services via the Minidriver). When I try to sign an EMail via Outlook I'm getting Error Message (Internal Error), the last call to the minidriver is for ReadFile with "cmapfile" When I try to sign an EMail via Outlook with a difference non-smartcard certificate it's work fine. When I try to sign a Data using CryptoAPI (based on Windows SDK Sample) it's working fine. I'm using Windows 7. someone got any idea how to debug this issue? I tried to enable the CAPI2 eventlog, it don't give me any good information.

• MS Surface drag & drop SurfaceListBoxItems

  - by Joe G

  Hey guys I'm working on the Microsoft Surface Table and I'm attempting to drag an item from 1 SurfaceListBox to another and recognize which SurfaceListBoxItem the other SurfaceListBoxItem was dropped on top of. The SDK help as a great tutorial for dragging items from 1 SurfaceListBox to the next and just adding the content and removing it from the other. If I set AllowDrop=True on the SurfaceListBoxItem the SurfaceListBox still captures the drop. If I set it to false on the SurfaceListBox it doesn't recognize the drop at all. Somehow I need to bury deeper on that drop or something.

• Passing a SAFEARRAY from C# to COM

  - by SlavaGu

  I use 3rd party COM to find faces in a picture. One of the methods has the following signature, from SDK: long FindMultipleFaces( IUnknown* pIDibImage, VARIANTARG* FacePositionArray ); Parameters: pIDibImage[in] - The image to search. FacePositionArray[out]- The array of FacePosition2 objects into which face information is placed. This array is in a safe array (VARIANT) of type VT_UNKNOWN. The size of the array dictates the maximum number of faces for which to search. which translates into the following C# method signature (from metadata): int FindMultipleFaces(object pIDibImage, ref object pIFacePositions); Being optimistic I call it the following way but get an exception that the memory is corrupt. The exception is thrown only when a face is present in the image. FacePosition2[] facePositions = new FacePosition2[10]; object positions = facePositions; int faceCount = FaceLocator.FindMultipleFaces(dibImage, ref positions); What's the right way to pass SAFEARRAY to unmanaged code?

• Need advice on speeding up tableViewCell photo loading performance

  - by ambertch

  I have around 20 tableview cells that each contain a number (2-5) thumbnail sized pictures (they are VERY small Facebook profile pictures, ex. http://profile.ak.fbcdn.net/hprofile-ak-sf2p/hs254.snc3/23133_201668_2989_q.jpg). Each picture is an UIImageView added to the cell's contentview. Scrolling performance is poor, and measuring the draw time I've found the UIImage rendering is the bottleneck. I've researched/thought of some solutions but as I am new to iphone development I am not sure which strategy to pursue: preload all the images and retrieve them from disk instead of URL when drawing cells (I'm not sure if cell drawing will still be slow, so I want to hold off on the time investment here) Have the cells display a placeholder image from disk, while the picture is asynchronously loaded (this seems to be the best solution, but I'm currently not sure exactly how to do best do this) There's the fast drawing recommendation from Tweetie, but I don't know that will have much affect if it turns out my overhead is in network loading (http://blog.atebits.com/2008/12/fast-scrolling-in-tweetie-with-uitableview/) Thoughts/implementation advice? Thanks!

• clicking the debug button in Eclipse will not start debug mode

  - by iHorse

  i am running Eclipse 3.5.0 on a MacBook Pro using the Android SDK. i noticed that on this particular project i am working on i cant seem to actually enter debug mode. i click the little green bug icon in the tool bar and the app starts and runs. but if i switch over to the Debug Perspective i see no indication that it is running in debug mode. furthermore i can not hit any brake points that i have set. this makes debugging code a bit hard. Other projects that i am working on don't have this issue. any ideas on what i need to change in the project to get this to work?

• Automated builds of BizTalk 2009 projects using Team System 2008 Build

  - by Doug

  I'm trying to configure automated build of BizTalk 2009 projects using Team Foundation Server 2008. We have a staging server which has BizTalk 2009 installed. I ran the Team Foundation Server Build Setup on this server, and it can build non-BizTalk projects OK. However, BizTalk projects fail to build. I suspected something was amiss when "Deployment" was not a valid build type! I tried copying various things over from a developer PC which has BizTalk and Visual Studio 2008 installed, but still couldn't get it to work. I don't really want to install Visual Studio on the staging server, but without it the "Developer Tools and SDK" option in the BizTalk install is greyed out. I guess I need this in order for BizTalk projects to compile. So, my question is can a BizTalk 2009 server be used as a TFS build agent to build BizTalk projects without having Visual Studio installed. If the answer is no, what's the smallest part of VS that can be installed to get this to work? Thanks in advance.

• where to get free 1440 cron jobs a day??

  - by Nok Imchen

  Well, I'm making a program for my own use. In this program, i need to set up cron job. The cron job should run every minute (24 hr * 60 mins = 1440 times). Thus, I'll need to set up a cron job with a frequency of 1 minute. I think Google app engine gives free cron job. But i'm very new to it. I downloaded the java SDK and read the document but understood nothing :( So, i cant use Google app engine. Is here any other free service like Google app engine which but with easier inferface??? all i want is a cron job with 1 minute frequency please help/suggest me.... thank you

• UITableViewCell imageView.contentMode doesn't work in 3.0

  - by JustinXXVII

  In UITableViewCellStyleDefault, setting the contentMode on the imageView has no result. If I change my build SDK to version 3.1, everything again works. I don't get any warnings or errors when compiling on 3.0 but this code: cell.imageView.contentMode = UIViewContentModeScaleAspectFit; cell.imageView.image = [UIImage imageNamed:[[NSString stringWithFormat:@"%@head.jpg",[gametype objectAtIndex:indexPath.row]]lowercaseString]]; seems to default to the UIViewContentModeCenter, so all of my pictures exceed the cell boundaries and encroach on neighboring cells. Let me reiterate that if I change my target to 3.1 everything works correctly and all pictures are scaled accordingly to fit in the default imageView Is this a known bug?

• Google Search api for Android systems

  - by jrharshath

  Hi, I'm trying to build an android app that would do a local search on google. I know there is a Google Search API for Java, and I am able to use it for a desktop application. However, when I use the same jar file (gsearch.jar) in my android project, Some problems arise. When I call the .localSearch() method of my gsearch.Client object, a runtime error is occurring. The error message is: "java.lang.VerifyError: gsearch.Client". This message is occurring in the Dalvik Debug Monitor log. So what is the problem here? Can I not use the search API on the android? More importantly, how do I do a local search from an android app? Does the android sdk have search APIs inbuilt? I could only find the Maps api, and Map search is not what I'm looking for.. Thanks for the help, jrh

• AsyncTask, RejectedExecutionException and Task Limit

  - by Samuh

  I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

• VS2008: Add custom build rule to a Property Sheet (vsprops)?

  - by shoosh

  I'm using the CUDA .rules file which comes with the CUDA SDK for custom build steps in my project. To save on property duplication I'd like to define the properties of the CUDA rule in a .vsprops file. For some reason, the CUDA rule branch of the properties tree does not show under any of my property sheets, only under the main configurations sheets. I tried editing the .vsprops with a text edition and add the section by hand but there is no change it still does't show when in visual studio. Is there a way to do this?

• xcode build to iphone chooses old invalid provisioning profile

  - by sapatos

  I've just gone through some pain with iphone and xcode upgrades and keychain failures etc and decided to uninstall xcode completely and re-install. This fixed my keychain issues however the project I am working on appears to be linked to an old invalid provisioning profile. I've deleted the profile from "Provisioning Profiles" in organiser, and removed it from Provisioning on the Iphone section of Organiser. However when I build an go with the iphone sdk rather than simulator i get the pop up "codesign wants to sign using key "OldKey" in your keychain". It appears the actual app is associated with the old key and I can't seem to find how to point it to the new valid one. Crazy thing is at some point I managed to get it to work and install but the application crashed and won't open. I've not managed to get it to install again. Any ideas?

• Problem using Blend 3 Interaction.Behaviours in VS2010

  - by Andre Luus

  There seems to be a problem with support for the Interactivity namespace of Blend 3 in the VS2010 xaml editor. I have the following installed: VS2010 Blend 3 + Blend 3 SDK I am trying to compile a demo project that is targeted at .Net 4 Client Profile and has a reference to System.Windows.Interactivity (in the Blend 3 folder). In the object browser everything appears to be fine. I can also access Interaction.Behaviours from code-behind, but if I put the namespace xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" in the xaml file and try to use it, the intellisense is blank. If I copy something in there anyway, the compiler says: The tag 'Interaction.Behaviors' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactivity'. Do I need to install Blend 4 RC or something?

• iPad UI clipped in simulator

  - by raj.tiwari

  My views created for iPad form factor look fine in Interface Builder. However, when I debug my app in iPhone Simulator 3.2 (with Hardware - Device set to iPad), I see the UI clipped and about half size. There is a 2x button at the bottom which lets me zoom in. But this just shows the same clipped UI in double size. This is really weird since I have created the XIB for iPad form factor and it is supposed to fit iPad completely. Any ideas what I might be doing wrong? I am using iPhone SDK 3.2 downloaded on 4/30/2010. Thanks. -Raj

• Team Foundation Error: The request ID is incorrect or not recognized

  - by Andrei

  Hello everybody. I'm trying to connect to the Team Foundation Server's ClientService.asmx web services. Over here, the TFS has webservices for retrieving work items, queries, metadata and more...a quite complete and useful set of information to get. My problem is that trying to access these services leads to an error: TF51313: The request ID is incorrect or not recognized I assume it has something to do with the RequestHeader Id structure. I give it a GUID inside the code I'm working on, but I don't know how correct it is...or what value it should have to begin with. Note: I can't use the TFS API/SDK because I am building a mobile application. Also an application on the TFS server side to communicate with the API and expose web services is not an option. Thanks.

• iPhone: CALayer + rotate in 3D + antialias?

  - by Colin

  Hi all, An iPhone SDK question: I'm drawing a UIImageView on the screen. I've rotated it in 3D and provided a bit of perspective, so the image looks like it's pointing into the screen at an angle. That all works fine. Now the problem is the edges of the resulting picture don't seem to be antialiased at all. Anybody know how to make it so? Essentially, I'm implementing my own version of CoverFlow (yeah yeah, design patent blah blah) using quartz 3d transformations to do everything. It works fine, except that each cover isn't antialiased, and Apples version is. I've tried messing around with the edgeAntialisingMask of the CALayer, but that didn't help - the defaults are that every edge should be antialiased... thanks!

• Referencing code in VB.NET

  - by akramnik

  I'm not at all familiar with VB.NET or ASP. I need to create a simple page which makes a call to a remote web service. I used the wsdl utility which comes with the DotNet SDK to generate a service proxy and write it to a VB file. Unfortunately I have no idea how to reference this code in either my ASPX file or the code behind VB file so I can create an instance of the proxy. Edit: I should have qualified this by noting that I'm not using visual studio. I just coded up a .aspx with a .vb behind it and dropped it into an IIS location. Is there a way to do what you're suggesting outside of VS?

• UITableView backgroundColor always grey on iPad

  - by rjobidon

  Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light grey background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light grey background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

• Where is a good place for a code review?

  - by Carlos Nunez

  Hi, all! A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together. Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed). Thanks, everyone! -Carlos Nunez

• Setting Xcode's target to iPhone NOT iPad

  - by Garry

  I just upgraded to iPhone SDK 3.2 Beta 4. Since doing so, I have not been able to get the app to launch in the iPhone simulator - it keeps launching in the iPad simulator. I have tried option-clicking the drop-down menu in the top left-corner of Xcode and setting 'Active Executable' to iPhone simulator 3.1.3 but it keeps going back to iPad simulator instead. What gives? I have no interest in my app running on the iPad and I don't want to test it in the 2X mode in the simulator. Thanks,

• How does COM registration work in Windows

  - by Air Benji

  I'm an application packager trying to make sense of how the COM registry keys (SelfReg) interrelate to the given .dll in Windows. ProgID's, AppID's, TypeLibs, Extensions & Verbs are all tied around the CLSID right? Do CLSID's always use Prog/App IDs or could you just have a file extension class? Which bits are optional? Some of it seems to be 'like a router' where there's the two interfaces (internal - .dll) and external (the extension etc). How does this all fit? (The SDK documentation doesn't make sense to me) I ask as this is all pivotal to application 'healing' with Windows Installer (which packagers are all 'big' on, but there's no nitty-gritty breakdowns since its a coder-thing really) ---Edit: Am I safe in assuming that for what COM is registered, it must all link back to the CLSID and cannot be a 'dead-end'? Verbs need extensions which need progid's... What about the AppId's, TypeLibs and Interfaces? How do they interrelate?

• TextToSpeech setOnUtteranceCompletedListener always returns -1 error?

  - by Robert Nekic

  I've been working with Android's TTS functions with general success however, one piece of it refuses to work for me; I can not successfully assign an OnUtteranceCompletedListener to my TextToSpeech object. I've tried implementing OnUtteranceCompletedListener in one of my classes and I've tried creating a new, stand-alone OnUtteranceCompletedListener instance. Both approaches are simple enough to implement and appear to yield proper listeners without exceptions...yet setOnUtteranceCompleteListener(myListener) ALWAYS returns -1 (ERROR). The documentation for this seems straight forward. Has anyone gotten this to work? I'm targeting SDK 4. Are there known issues with this with SDK4/v1.6?
