• Returning a C++ reference in a const member functionasses

  - by Chris Kaminski

  A have a class hierarchy that looks somethign like this: class AbstractDataType { public: virtual int getInfo() = 0; }; class DataType: public AbstractDataType { public: virtual int getInfo() { }; } class Accessor { DataType data; public: const AbstractDataType& getData() const { return(data); } } Well, GCC 4.4 reports: In member function ‘const AbstractDataType& Accessor::getData() const’: error: invalid initialization of reference of type ‘const AbstractDataType&’ from expression of type ‘const DataType’ Where am I going wrong - is this a case where I MUST use a pointer?

• C++ Class Inheritance architecture - preventing casting

  - by Some One

  I have a structure of base class and a couple of inherited classed. Base class should be pure virtual class, it should prevent instantiation. Inherited classes can be instantiated. Code example below: class BaseClass { public: BaseClass(void); virtual ~BaseClass(void) = 0; }; class InheritedClass : public BaseClass { public: InheritedClass1(void); ~InheritedClass1(void); }; class DifferentInheritedClass : public BaseClass { public: DifferentInheritedClass(void); ~DifferentInheritedClass(void); }; I want to prevent the following operations to happen: InheritedClass *inherited1 = new InheritedClass(); DifferentInheritedClass *inherited2 = new DifferentInheritedClass (); BaseClass *base_1 = inherited1; BaseClass *base_2 = inherited2; *base_1 = *base_2;

• Removing files on a limit access backup server

  - by Bart van Heukelom

  I have an account on a backup server but it's full, so I need to clear it. The problem is that It's only accessible via FTP, SFTP and Rsync (no shell) Deleting lots of small files (as in, multiple full Linux installations), which I have to do, is undoable over FTP/SFTP because it cannot recursively delete directories in one command (Yes, most clients will fake this by issueing all the seperate commands for you but the overhead is huge and the process takes several days...well it crashes before that). What do I do?

• Oracle Professional Developer, Ver. 6.0.33 for MS-DOS

  - by Frank Developer

  Hi, I'm trying to install this fossil in DOS 6.22, which is running in Microsoft Virtual PC 2007. I'm hoping that some of you veteran Oracle developers have any recollection of in what order do these diskette images need to be loaded, since I don't have any documentation available for 6.0.33. A friend emailed me the following 720K diskette images: INSTALLE.IMG RDBMS1.IMG RDBMS2.IMG RDBMS3.IMG RSF.IMG SQLLDR1.IMG SQLLDR2.IMG UTIL1.IMG UTIL2.IMG UTIL3.IMG Within Virtual PC, I capture a diskette image, one at a time, into Drive A: VPC's floppy disk emulation supports FAT12, so the supported diskette formats can be: 720K or 1.44MB. If anyone happens to have documentation for this legacy version, I would greatly appreciate a copy of it! Thank You.

  - by user119333

  Hi, When my user press "ENTER" on the virtual android "user validate entry!" keybord my keybord stay visible ! (Why?) Here my Java code... private void initTextField() { entryUser = (EditText) findViewById(R.id.studentEntrySalary); entryUser.setOnKeyListener(new OnKeyListener() { public boolean onKey(View v, int keyCode, KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_DOWN) { switch (keyCode) { case KeyEvent.KEYCODE_DPAD_CENTER: case KeyEvent.KEYCODE_ENTER: userValidateEntry(); return true; } } return true; } }); } private void userValidateEntry() { System.out.println("user validate entry!"); } ... here my View <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <EditText android:id="@+id/studentEntrySalary" android:text="Foo" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> Maybe something wrong on my virtual device ?

• C++: warning: '...' declared with greater visibility than the type of its field '...::<anonymous>'

  - by Albert

  I'm getting these two warnings (with GCC 4.2 on MacOSX): /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than the type of its field 'startMainLockDetector()::MainLockDetector::<anonymous' /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than its base 'Action' In this code: struct Action { virtual ~Action() {} virtual int handle() = 0; }; static void startMainLockDetector() { /* ... */ struct MainLockDetector : Action { bool wait(Uint32 time) { /* ... */ } int handle() { /* ... */ } }; /* ... */ } I'm not exactly sure what these warnings mean (what visibility?) and how to fix them. (I really want the class MainLockDetector to be local for that function only.) I have already compiled the same code with a lot of other compilers (clang, GCC 3.*, GCC 4.0, GCC 4.4, etc) and never got any warning for this code.

• Descending list ordered by file modification time

  - by user62367

  How can i generate a list of files in a directory [e.g.: "/mnt/hdd/PUB/"] ordered by the files modification time? [in descending order, the oldest modified file is at the lists end] ls -A -lRt would be great: https://pastebin.com/raw.php?i=AzuSVmrJ but if a file is changed in a directory it lists the full directory...so the pastebined link isn't good [i don't want a list ordered by "directories", i need a "per file" ordered list] os: openwrt..[no perl - not enough space for it :( + no "stat", or "file" command] Thank you!

• different .bashrc files for different login nodes?

  - by 130490868091234

  Can I have different .bashrc files loading when logging into different nodes that share the same home dir? This is, I am mostly interested to loading different PATH directories when logging as bash, depending on the different Linux nodes I log into? For example, if I log into bash in machine abc-01, I would like to have a given .bashrc loaded, but when I log into abc-02, that uses the same /home/username directory, I would like to use a different .bashrc. How can I go about doing that?

• GNU-Screen still has only old groups for my username.

  - by Dan

  I was recently added to a group on the unix server. My active screen session has not been update to the new groups: $groups A B C D $screen -r $groups A B C Without closing my screen session is there a way for me to use my new privileges in the screen session? Or if not, is there at least a way I can save all of the different directories each of the tabs are on? Thanks, Dan

• Store profile image of all users into single directory or per subdirectory id?

  - by Luccas

  I'm using amazon s3 as storage for users profile pic. I see that many websites generates large random filenames and put them into the same root directory like: http://xxx.us-east-1.amazonaws.com/aHR0cHM6Ly9mYmNkbi1wcm9maWxlLWEuYWthbWFpaGQubmV0L2hwcm9maWxlLWFrLWFzaDIvMjczMzkxXzEwMDAwMDMxMjAxMzg5OV81NTk3MjM4Mzdfbi5qcGc.jpg And my question is: What are the pros and cons of that approach? If I palce them into different directories, what problems I will have in future? http://xxx.us-east-1.amazonaws.com/users/id/username.jpg or http://xxx.us-east-1.amazonaws.com/users/id/random_number.jpg Thanks!

• What causes my borderless C++ app to crash when overriding WndProc?

  I use a form with border NONE. I need to override WndProc for resize and move form. However, using this code, my app crashes! static const int WM_NCHITTEST = 0x0084; static const int HTCLIENT = 1; static const int HTCAPTION = 2; protected: virtual void Form1::WndProc(System::Windows::Forms::Message %m) override { switch (m.Msg) { case WM_NCHITTEST: if (m.Result == IntPtr(HTCLIENT)) { m.Result = IntPtr(HTCAPTION); } break; } Form1::WndProc(m); } virtual System::Windows::Forms::CreateParams^ get() override { System::Windows::Forms::CreateParams^ cp = __super::CreateParams; cp->Style |= 0x40000; return cp; } How can I fix my code not to crash but still allow my form to be moved and resized?

• declaring a 2D array of pointer objects

  - by Tyler Stennette

  I'm having a tough time figuring out how to instantiate a 2D array of pointer objects. Here is how I'm doing it: Pieces* chessBoard[9][9]; When I want to set it to an actual object pointer, I'm doing the following: chessBoard[1][1] = new Rook(p1Rook); Rook is a class that inherits attributes from the Pieces class and p1Rook is a char variable set to 'R'. This class also implements virtual functions (not pure virtual) from Pieces such as move() or getPiece() that are unique to the particular chess piece. However, when I compile my program, I get the following error: ChessBoard.cpp:69: error: expected type-specifier before ‘Rook’ ChessBoard.cpp:69: error: cannot convert ‘int*’ to ‘Pieces*’ in assignment Can someone please explain what I should change to get rid of this rather annoying persistent error? I would appreciate it.

• have Powershell get-childitem return files only

  I'd like to use get-childitem recursively, but only have it return files not directories. The best solution I have just doesn't seem natural: gci . *.* -rec | where { $_.GetType().Name -eq "FileInfo" }

• Will Bitlocker make it impossible to read my files from my dual booting Ubuntu OS?

  When I activate BitLocker, I imagine that will make it impossible to read any files on my Windows partition from my Ubuntu installation. Is that correct? Any way to not encrypt certain directories so I can access them from Ubuntu?

• Hierarchy inheritance

  - by reito

  I had faced the problem. In my C++ hierarchy tree I have two branches for entities of difference nature, but same behavior - same interface. I created such hierarchy trees (first in image below). And now I want to work with Item or Base classes independetly of their nature (first or second). Then I create one abstract branch for this use. My mind build (second in image below). But it not working. Working scheme seems (third in image below). It's bad logic, I think... Do anybody have some ideas about such hierarchy inheritance? How make it more logical? More simple for understanding? Image Sorry for my english - russian internet didn't help:) Update: You ask me to be more explicit, and I will be. In my project (plugins for Adobe Framemaker) I need to work with dialogs and GUI controls. In some places I working with WinAPI controls, and some other places with FDK (internal Framemaker) controls, but I want to work throw same interface. I can't use one base class and inherite others from it, because all needed controls - is a hierarchy tree (not one class). So I have one hierarchy tree for WinAPI controls, one for FDK and one abstract tree to use anyone control. For example, there is an Edit control (WinEdit and FdkEdit realization), a Button control (WinButton and FdkButton realization) and base entity - Control (WinControl and FdkControl realization). For now I can link my classes in realization trees (Win and Fdk) with inheritence between each of them (WinControl is base class for WinButton and WinEdit; FdkControl is base class for FdkButton and FdkEdit). And I can link to abstract classes (Control is base class for WinControl and FdkControl; Edit is base class for WinEdit and FdkEdit; Button is base class for WinButton and FdkButton). But I can't link my abstract tree - compiler swears. In fact I have two hierarchy trees, that I want to inherite from another one. Update: I have done this quest! :) I used the virtual inheritence and get such scheme (http://img12.imageshack.us/img12/7782/99614779.png). Abstract tree has only absolute abstract methods. All inheritence in abstract tree are virtual. Link from realization tree to abstract are virtual. On image shown only one realization tree for simplicity. Thanks for help!

• Are view models used in rails?

  - by Valentin Vasilyev

  I'm starting to develop a small application in ruby on rails and many questions arise. I should say that I have about 1 year of experience with ASP.NET MVC and feel at home with models views and controllers. I've been using view models extensively (with the help of AutoMapper) and now wondering if view models are used similarly in rails camp. From various examples (rails casts mainly) I've gathered that it is common to either combine data from multiple models right in your view (which is frowned upon in ASP.NET MVC), or to use virtual attributes on models to obtain "missing" data. I know that business model should not be modelled after UI needs, for example there should not be a 'password confirm' property in your model, this should be a view model property. Rails virtual properties seem to violate this principle. How is it done in rails? Thanks.

• Renaming dates under windows cmd

  - by ldigas

  I have a bunch of directories (folders, if you like) that follow this pattern \20121022 Description of the directory's contents goes here\ (some don't have it, just the date) and I need to rename them to follow the following pattern \2012-10-22 Description of the directory's contents ...\ Is there a way to do it using Windows cmd and the tools that come with it (namely, ren)? If not, what would be the most portable way to do it? I have a very restricted set of privileges on the machine I'm doing this on.

• C# - Sending keyboard events to (last) selected window

  - by Mil

  Hi guys, I want to use virtual keyboard assembly found here http://www.codeproject.com/KB/miscctrl/touchscreenkeyboard.aspx like on screen keyboard (OSK.exe) in Windows. Can someone please tell me how can I use it so that it always stays on top and yet for user to be able to select other windows on dekstop for keyboard input, just like "on screen keyboard" in Windows, specifically I don't know how to select last selected window (can't use GetForegroundWindow or GetFocus only, because when user clicks on virtual keyboard it gets focused and I get handle of keyboard window itself)? This is very urgent to me so any advice would be greatly appreciated. Thanks in advance.

Apple´s File-Fault is using kerberos, but file-fault data isnt´ accessible via nfs. Is there a possibility to use file-vault anyway or should we use truecrypt volumes? How do we setup truecypt/filevault + nfs?

• Which Files located under C:\ are Necessary for Win7 to Boot?

  - by k0pernikus

  I had my greatest moment of incredible stupidity and deleted all hidden files of the Windows partition, most commonly known as C:\, while running Gnu/Linux. All the directories are intact. I instantly unmounted it, and run ntfsundelete, though of the thousands entries I wonder which ones I have to recover. So hence my question: Which files located directly under C:\ are necessary for Windows 7 to boot?
