• LiveView plugin template creates lots of errors?

  - by Shedo Surashu

  I'm trying to get the LiveView plugin template to work but upon import of the project into Eclipse, I already have 13 errors and 2 warnings. I have already downloaded SDK for Android 1.6 which I believe is what it requires. The errors are as follows: The method startPlugin() of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 173 Java Problem The method stopPlugin() of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 182 Java Problem The method onSharedPreferenceChanged(SharedPreferences, String) of type new SharedPreferences.OnSharedPreferenceChangeListener(){} must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 360 Java Problem The method onServiceDisconnected(ComponentName) of type new ServiceConnection(){} must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 345 Java Problem The method onServiceConnected(ComponentName, IBinder) of type new ServiceConnection(){} must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 318 Java Problem The method screenMode(int) of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 230 Java Problem The method openInPhone(String) of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 221 Java Problem The method run() of type SandboxPluginService.Rotator must override a superclass method SandboxPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins/sandbox line 254 Java Problem The method onUnregistered() of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 216 Java Problem The method run() of type SandboxPluginService.Timer must override a superclass method SandboxPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins/sandbox line 235 Java Problem The method displayCaps(int, int) of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 206 Java Problem The method button(String, boolean, boolean) of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 196 Java Problem The method getPluginName() of type AbstractPluginService.LiveViewCallback must override a superclass method AbstractPluginService.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/src/com/sonyericsson/extras/liveview/plugins line 191 Java Problem and the warnings: The method getInterfaceDescriptor() from the type IPluginServiceV1.Stub.Proxy is never used locally IPluginServiceV1.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/gen/com/sonyericsson/extras/liveview line 242 Java Problem The method getInterfaceDescriptor() from the type IPluginServiceCallbackV1.Stub.Proxy is never used locally IPluginServiceCallbackV1.java /com.sonyericsson.extras.liveview.plugins.PluginPreferences/gen/com/sonyericsson/extras/liveview line 130 Java Problem These all occur fresh from the ZIP file from Sony Mobile's Developer World.

• AVCam memory low warning

  - by Red Nightingale

  This is less a question and more a record of what I've found around the AVCam sample code provided by Apple for iOS4 and 5 camera manipulation. The symptoms of the problem for me were that my app would crash on launching the AVCamViewController after taking around 5-10 photos. I ran the app through the memory leak profiler and there were no apparent leaks but on inspection with the Activity Monitor I discovered that something called mediaserverd was increasing by 17Mb every time the camera was launched and when it reached ~100Mb the app crashed with multiple low memory warnings.

• Must web apps support back button?

  - by Patrick Peters

  I did a system test on a new ASP.NET app. I encountered several exceptions when using the BACK button in my browser (IE 7). I stated in a review-record that the web-app must support the use of a BACK button (or at least handle it gracefully with for example session-time out warnings). The teamlead did not agree with me as he stated that a web-app should not support working with the back-button by default. Do you agree?

• Can i openly speculate based on App rejection that the iPad has xxx MB of memory?

  - by GamingHorror

  If i were to calculate the iPad's amount of RAM based on just the one fact that my iPad App got rejected due to memory warnings twice, and me fixing it, would this violate the developer NDA? Obviously i know how much memory my App uses, how much the iPhone OS is likely to use and estimate the amount reserved for video memory, then i can deduct from that that the iPad has xxx MB of memory. I just wonder if i can say that number publicly without violating any NDA?

• Get JS file via HTTPS from a HTTP page

  - by Mike

  Okay, so what are the ramifications of getting a JS file via an HTTPS call while on a HTTP page. I assume it would just be a little bit of extra overhead. Would there be any warnings about this call from any certain browser? Don't ask why. It's just hypothetical.

• How do I edit error messages in GCC source

  - by user299274

  Hi, I am trying to create a C Compiler in my native language which I intend to put up as open source. I want to do this by downloading the GCC source code and then manually translating the error messages and warnings into my target language. I am a beginner to GCC. Any idea where the error messages are located in the source code and how can I edit them?

• Adding ObsoleteAttribute to (or otherwise greylisting) Types not under my control?

  - by Michael Stum

  Is there a way to somehow mark Types I do not control as Obsolete? Basically I would like to add ObsoleteAttribute to types I do not want to use in my .net Project (i.e., SerializableAttribute) I believe I can do something like that with FxCop, but ideally I would like to have the compiler already generate warnings for "greylisted" Types? This should be on a Per-Project level, but sadly "Extension Attributes" don't exist, and adding them at Runtime is too late for ObsoleteAttribute...

• #ifdef with gfortran 77

  - by ccook

  I am using gfortran to compile FORTRAN 77 and would like to have DEBUG build options by using the preprocessor directive #ifdef. However, when I use them I get compile time warnings "Illegal preprocessor directive". Is it possible to have this functionality without deviating from the standard toolchain?

• C++ vs. C++/CLI: Const qualification of virtual function parameters

  - by James McNellis

  [All of the following was tested using Visual Studio 2008 SP1] In C++, const qualification of parameter types does not affect the type of a function (8.3.5/3: "Any cv-qualifier modifying a parameter type is deleted") So, for example, in the following class hierarchy, Derived::Foo overrides Base::Foo: struct Base { virtual void Foo(const int i) { } }; struct Derived : Base { virtual void Foo(int i) { } }; Consider a similar hierarchy in C++/CLI: ref class Base abstract { public: virtual void Foo(const int) = 0; }; ref class Derived : public Base { public: virtual void Foo(int i) override { } }; If I then create an instance of Derived: int main(array<System::String ^> ^args) { Derived^ d = gcnew Derived; } it compiles without errors or warnings. When I run it, it throws the following exception and then terminates: An unhandled exception of type 'System.TypeLoadException' occurred in ClrVirtualTest.exe Additional information: Method 'Foo' in type 'Derived'...does not have an implementation. That exception seems to indicate that the const qualification of the parameter does affect the type of the function in C++/CLI (or, at least it affects overriding in some way). However, if I comment out the line containing the definition of Derived::Foo, the compiler reports the following error (on the line in main where the instance of Derived is instantiated): error C2259: 'Derived': cannot instantiate abstract class If I add the const qualifier to the parameter of Derived::Foo or remove the const qualifier from the parameter of Base::Foo, it compiles and runs with no errors. I would think that if the const qualification of the parameter affects the type of the function, I should get this error if the const qualification of the parameter in the derived class virtual function does not match the const qualification of the parameter in the base class virtual function. If I change the type of Derived::Foo's parameter from an int to a double, I get the following warning (in addition to the aforementioned error, C2259): warning C4490: 'override': incorrect use of override specifier; 'Derived::Foo' does not match a base ref class method So, my question is, effectively, does the const qualification of function parameters affect the type of the function in C++/CLI? If so, why does this compile and why are there no errors or warnings? If not, why is an exception thrown?

• How to migrate the Access database to MOSS 2007 sql server with the use of SSMA (sql server migratio

  - by pointlesspolitics

  Hi, One of my friends got the access database with Forms (VBA) and wish to migrate all the database table to the newly installed MOSS 2007 site. He is using SSMI for this purpose. He cannot do it because there are plenty of errors and warnings. I think it is due to the old Access queries. Is there any other way to import the database to sql 2005 from access ? Thanks

• build errors with Crypto++ on iphone

  - by Joey

  I am trying to build Crypto++ for iPhone but encountering issues. I managed to get it to build to the device by removing a few .asm files and test.cpp but two issues: 1) the simulator gets build errors relating to: {standard input}:13583:suffix or operands invalid for `call' 2) there are hundreds of warnings (kind of annoying) Has anyone gotten crypto++ to work on iphone and found a way to resolve these issues?

• web.config File Section Replacements

  - by simon831

  I have a web deployment project that does a web.config section replacement using an external file. (this is to change the connection strings section). The web.config section replacement works fine when built manually, but when built as part of a TFS build the section is not replaced. I cannot find any errors or warnings in the build log. What are the likely causes, or how can I 'debug' this?

  Is there any way to write to the XCode build transcript? What i want to do, is throw a warning if a device is not attached to the computer instead of an assertion failure in my unit test cases (some cases rely on an attached ipod). I thought of something like the standard compiler warnings (only with custom message). Thanks.

• MySQL forgot about automatically creating an index for a foreign key?

  - by bobo

  After running the following SQL statements, you will see that, MySQL has automatically created the non-unique index question_tag_tag_id_tag_id on the tag_id column for me after the first ALTER TABLE statement has run. But after the second ALTER TABLE statement has run, I think MySQL should also automatically create another non-unique index question_tag_question_id_question_id on the question_id column for me. But as you can see from the SHOW INDEXES statement output, it's not there. Why does MySQL forget about the second ALTER TABLE statement? By the way, since I have already created a unique index question_id_tag_id_idx used by both question_id and tag_id columns. Is creating a separate index for each of them redundant? mysql> DROP DATABASE mydatabase; Query OK, 1 row affected (0.00 sec) mysql> CREATE DATABASE mydatabase; Query OK, 1 row affected (0.00 sec) mysql> USE mydatabase; Database changed mysql> CREATE TABLE question (id BIGINT AUTO_INCREMENT, html TEXT, PRIMARY KEY(id)) ENGINE = INNODB; Query OK, 0 rows affected (0.05 sec) mysql> CREATE TABLE tag (id BIGINT AUTO_INCREMENT, name VARCHAR(10) NOT NULL, UNIQUE INDEX name_idx (name), PRIMARY KEY(id)) ENGINE = INNODB; Query OK, 0 rows affected (0.05 sec) mysql> CREATE TABLE question_tag (question_id BIGINT, tag_id BIGINT, UNIQUE INDEX question_id_tag_id_idx (question_id, tag_id), PRIMARY KEY(question_id, tag_id)) ENGINE = INNODB; Query OK, 0 rows affected (0.00 sec) mysql> ALTER TABLE question_tag ADD CONSTRAINT question_tag_tag_id_tag_id FOREIGN KEY (tag_id) REFERENCES tag(id); Query OK, 0 rows affected (0.10 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql> ALTER TABLE question_tag ADD CONSTRAINT question_tag_question_id_question_id FOREIGN KEY (question_id) REFERENCES question(id); Query OK, 0 rows affected (0.13 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql> SHOW INDEXES FROM question_tag; +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | question_tag | 0 | PRIMARY | 1 | question_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | PRIMARY | 2 | tag_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | question_id_tag_id_idx | 1 | question_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | question_id_tag_id_idx | 2 | tag_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 1 | question_tag_tag_id_tag_id | 1 | tag_id | A | 0 | NULL | NULL | | BTREE | | +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ 5 rows in set (0.01 sec) mysql>

Where can I write my logs without running afoul of the default security settings? In addition, this has to work on Windows XP, Vista, and 7. Extra points if all users can write to the same set of log files.

• Why do I not get low memory issues until images are draw on the screen?

  - by maxpower

  I am able to load over 200 UIImage objects into a NSMutableDictionary without any memorry warning issues. When I start displaying them on the screen (after about showing 10-20 images) I get low memory warnings and an eventual crash. Only about 8 images are displayed at anyone time. Does it take additional memory to actually draw a UIImage on the screen? No memory leaks are showing up and i've reviewed code for leaks many many times.
