  • R.java file not updating with UI element's id

    - by Mohit Deshpande
    I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?

  • Pros and Cons of C vs C++ programming

    - by Mohit Deshpande
    I am trying to decide on whether I should learn C or C++. I come from a very object-oriented background of java and C#. I have heard that C++ is more object-oriented than C, BUT I have also heard that a C program compiles and runs faster than a C++ program. Please help me get the facts straight by giving pros and cons of BOTH points of views. (Points of views being C over C++, or C++ over C)

  • ISO C++ forbids declaration of 'QPushButton' with no type in QT Creator

    - by Mohit Deshpande
    I am running QT Creator on a Linux Ubuntu 9.10 machine. I just got started with QT Creator, and I was going through the tutorials when this error popped up while I was trying to build my project: "ISO C++ forbids declaration of 'QPushButton' with no type". This problem appears in my header file: #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui/QWidget> namespace Ui { class MainWindow; } class MainWindow : public QWidget { Q_OBJECT public: MainWindow(QWidget *parent = 0); ~MainWindow(); public slots: void addContact(); void submitContact(); void cancel(); private: Ui::MainWindow *ui; QPushButton *addButton; QPushButton *submitButton; QPushButton *cancelButton; QLineEdit *nameLine; QTextEdit *addressText; QMap<QString, QString> contacts; QString oldName; QString oldAddress; }; #endif // MAINWINDOW_H

  • Implement subitem in SQLite

    - by Mohit Deshpande
    How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a parent task. How would I implement this in SQLite for Android? NOT IN SQL! So no foreign keys (triggers are allow, though)! Could I just have a separate table (subtask) and have a foreign key trigger to link subtask(INTEGER parent) to task(INTEGER PRIMARY KEY AUTOINCREMENT _id)? Or should I add a column to my original task table(INTEGER parent)? How could I implement this?

  • Poster image on embedded youtube video

    - by Srijan Deshpande
    Hi, I want to embed a youtube video on my website and I need to replace the default poster image that shows up on the video with a jpg of my own. The default image that shows up is a scaled-up thumbnail and is therefore very blurry and pixelated and I need to use a hi-res jpg in place of it. I'm aware that youtube only allows us to pick one of three auto-generated thumbnails, but does that restriction also apply to youtube videos embedded on an external website? If so, is there an alternate way to do this? Thanks!

  • Include headers in header file?

    - by Mohit Deshpande
    I have several libraries made by myself (a geometry library, a linked list library, etc). I want to make a header file to include them all in one lib.h. Could I do something like this: #ifndef LIB_H_ #define LIB_H_ #include <stdio.h> #include <stdlib.h> #include <linkedlist.h> #include <geometry.h> .... #endif Then I could just reference this one library and actually reference multiple libraries. Is this possible? If not, is there a way around it?

  • android.R.layout.simple_list_item_checked not toggling in ListView

    - by Mohit Deshpande
    Here is my custom adapter: ... @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(android.R.layout.simple_list_item_checked, parent, false); return v; } ... Now this visually appears to be exactly what I needed. The problem is that I can't get toggle the checked state when I click on the listview item. Any solutions?

  • Compile multiple C files with make

    - by Mohit Deshpande
    (I am running Linux Ubuntu 9.10, so the extension for an executable is executablefile.out) I am just getting into modular programming (programming with multiple files) in C and I want to know how to compile multiple files in a single makefile. For example, what would be the makefile to compile these files: main.c, dbAdapter.c, dbAdapter.h? (By the way, If you haven't figured it out yet, the main function is in main.c) Also could someone post a link to the documentation of a makefile?

  • Good Database with C library?

    - by Mohit Deshpande
    What is a good database with support for C? I want a database that can persist changes when the program is closing and retrieve them when the user starts up the program. I was thinking maybe like SQLite or Berkeley DB. Some documentation would be great too.

  • #Define's scope throughout library?

    - by Mohit Deshpande
    Say I have a constant: #define PI 3.14 Say I have a static library with multiple header and source files. If I declare this in the header file, will its scope apply to all of the source files? Or do the source files need to include the header with the declaration of PI?

  • How would someone implement mathematical formulae in java?

    - by Mohit Deshpande
    What I mean is like have to user input a string with multiple variables and get the value of those variable. Like a simple quadratic formula: x^2 + 5x + 10. Or in java: (Math.pow(x,2)) + (x * 5) + 10The user would then enter that and then the program would solve for x. I will be using the BeanShell Interpreter class to interpret the string as an equation. But how would I solve for x?
