I am learning java application ..without giving exception my prg is giving error..i want to know some thing?

(App.java:13)
what does the numbers 18,13 etc means
I am learning java application ..without giving exception my prg is giving error..i want to know some thing?
may be the line numbers of your coding
Reply:Firstly, I hope you understand the error was given because you are dividing a number, 1 in this case, by 0. This will always an exception.
Secondly, the numbers that are given out is a dump of the stack.
The stack basically holds the path that was taken to get to the exception, then when the exception happens, it produces what is called a stack trace.
You can trace the exception back through this stack to find out where the exception was called from in your program, etc. I hope that did not confuse you.
Basically, you stack trace reads as such,
The exception called ArithmeticException is thrown at line 36 of your App program.
Line 29 called the method the method that threw the exception, I presume it is the line the says 'd();'
Line 24 called the 'c' method, 'c();'.
Line 18 called the 'b' method, 'b();'.
Line 13 called the 'a' method, 'a();'.
Therefore, you can see the program worked correctly,
main called a, a called b, b called c, c called d, d threw the exception.
Reply:siscuss @ http://www.studyjava.org
Reply:It means exception raised at 29 (i/j)... here u r not handling exceptions so its thrown to its caller functiion (c())... 24 is line no of d(); in c() function.

1) DC stands for direct current. An example is a battery with a positive and negative terminal. Household electricity is AC which stands for alternating current.
2) The units of resistance are Ohms. Volts are units of electric potential, Amperes are units of current, and "conductor" isn't an electrical unit.
3) Electrical current is the type of current that is a flow of electrons, it can be either alternating or direct.
4) A wire that melts in excessive electrical current is a fuse, when the wire melts it breaks the circuit. This is intended to protect the circuit from damage.
5) As I said before, homes use AC which stands for alternating current. Edison originally was a propoent of direct current, but alternating current becamse the standard because it could be transmitted more efficiently over long distances.
6) Units of resistance are Ohms, it seems strange that this question is repeated.
7) Static electricity is when a material builds up a charge, the charge can be positive (fewer electrons than protons) or negative (more electrons than protons). Static discharge occurs when there is sufficient charge built up to cause the electrons to jump from a negatively charged material to a positively or less negatively charged material.
8) Insulators are poor conductors of electricity. Wires are made from materials that are good conductors of electricity, usually a metal such as copper. Generators convert mechanical energy into electrical energy, generally by moving a conductor through a magnetic field.

Can somebody explain to me that simple C# loop plz?
using System;
class UseDecimal {
public static void Main() {
decimal price;
decimal discount;
decimal discounted_price;
// compute discounted price
price = 19.95m;
discount = 0.15m; // discount rate is 15%
discounted_price = price - ( price * discount);
Console.WriteLine("Discounted price: $" + discounted_price);
}
}
The output from this program is shown here:
Discounted price: $16.9575
Sorry I am trying to find out how do we get $16.9575??
Thanks for explaining into details. I am learning C# and I have trouble to understand the for loop for some reason!1 I understand other loops but the (FOR) loop gives me issues.
Can somebody explain to me that simple C# loop plz?
it's self explantory if you look at the line
// compute discounted price
price = 19.95m;
discount = 0.15m; // discount rate is 15%
discounted_price = price - ( price * discount);
It sounds like to me you are having a mental block at the moment.
The best thing to do is to just take a breather away from what you are frustrated over and come back to it later. Sometimes it ends up clicking when you do that.
Also, when learning something new, try not to let your brain make it more complicated that it is. Are you taking classes or are you just reading books?

Creating assemblies for C# Console app.?
I'm a C# newbie, without any previous knowledge/experience in programming.
So I've been trying my hand at a few console apps at the moment.
I created five programs, viz. Prime numbers.cs, array_manipulation.cs, calculator.cs, factorial.cs, and Fibonacci.cs
All these files have the same namespace "Ritz".
Moreover, they are part of the same project and each of them has their own static Main function.
Now what I wanna do is create a WinForm,and place buttons on the form to launch these console apps.
Please help me out with this, I am a newbie, but obedient, and will get the hang of any sort of jargon you wanna use........
I'll post the source codes if that would help you to help me......
Thanks,
Ritz
Creating assemblies for C# Console app.?
Somewhere under Project Properties you can change your application type to a Windows Application, instead of a Console Application.
I really recommend you just create a new Windows Application project, usually a file called Program.cs is created with a special Main() function preconfigured to launch a window.
You can use the Process.Start() command to trigger your console apps to run as other processes.

How can I run an exe file by C# Windows programming?
How can I run an exe file by C# Windows programming? I have problems in running an exe file by clicking the button that i made in c# windows programing, can anyone of you write the code of event handler in c# through which i can run exe file by just clicking the button,rest of the code is:
using System;
using System.Windows.Forms;
using System.Drawing;
class ButtonForm : Form {
Button MyButton = new Button();
public ButtonForm() {
Text = "Respond to a Button";
MyButton = new Button();
MyButton.Text = "Press Here";
MyButton.Location = new Point(100, 200);
// Add button event handler to list.
MyButton.Click += new EventHandler(MyButtonClick);
Controls.Add(MyButton);
}
[STAThread]
public static void Main() {
ButtonForm skel = new ButtonForm();
Application.Run(skel);
}
// Handler for MyButton.
{ Please guide me with this part.
}
}
Thank u in advance.
How can I run an exe file by C# Windows programming?
Okay, you already have a function defined, you need to go to your Form.cs file, where the EventHandler is located.
MyButton.Click += new EventHandler(MyButtonClick);
This points to the MyButtonClick function.
**************************************...
Now you need to add:
using System.Diagnostics;
Then create a process:
Process TheProcessYouNamed;
private void MyButtonClick(object sender, EventArgs e)
{
TheProcessYouNamed = Process.Start("EXEToRun.exe");
TheProcessYouNamed.CloseMainWindow();
}
using System;
using System.Windows.Forms;
using System.Drawing;
class ButtonForm : Form {
Button MyButton = new Button();
public ButtonForm() {
Text = "Respond to a Button";
MyButton = new Button();
MyButton.Text = "Press Here";
MyButton.Location = new Point(100, 200);
// Add button event handler to list.
MyButton.Click += new EventHandler(MyButtonClick);
Controls.Add(MyButton);
}

How do I fix this problem in C++?
I need to know how to properly use the SetTimer() function in C++ from windows.h.. Please helm me about this... I have this code, but it doesn't seem to have any result...
#include %26lt;windows.h%26gt;
#include %26lt;iostream%26gt;
#include %26lt;conio.h%26gt;
using namespace std;
HANDLE curhndl();
int i = 0;
void proc();
main()
{
void (*fptr)() = %26amp;proc;
SetTimer((HWND)curhndl(), 1, 1, fptr());
getch();
cout%26lt;%26lt;i;
getch();
}
void proc()
{
i++;
}
HANDLE curhndl()
{
static bool called;
static HANDLE hwnd;
if (called != true){
hwnd = GetStdHandle(STD_OUTPUT_HANDLE);
if (hwnd == INVALID_HANDLE_VALUE){ return INVALID_HANDLE_VALUE; }
called = true; }
return hwnd;
}
How do I fix this problem in C++?
Sorry to say, but your code is ABSOLUTELY incorrect. Sorry again :(
If you want to use API timers, you should spin message loop. The handle (that you pass to SetTimer) should be not the standard output or whatever, but a handle of a real window (that is why it is of HWND type)! If you pass to SetTimer something different from a window handle (even if you cast it to HWND as you smartly did :) ), the function will fail and will not create a timer.
I don't think it is a good idea to use API timers in console application at all - they are not designed to work this way. Try windowed application.
Reply:I think there may be a few problems with the code. One that jumps out at me is in HANDLE curhndl().
You are not initializing 'static bool called', so it starts off as a garbage value (not 0). Since 'true' means 'not-zero', called will likely always be true. That means GetStdHandle never executes.
Hope that helps. Good luck!

I don't think it is a good idea to use API timers in console application at all - they are not designed to work this way. Try windowed application.
Reply:I think there may be a few problems with the code. One that jumps out at me is in HANDLE curhndl().
You are not initializing 'static bool called', so it starts off as a garbage value (not 0). Since 'true' means 'not-zero', called will likely always be true. That means GetStdHandle never executes.
Hope that helps. Good luck!

Assuming Point is a class type with a public copy constructor, iden¬tify each use of the copy constructor in this program fragment:
Point global;
Point foo_bar(Point arg)
{
Point local = arg;
Point *heap = new Point(global);
*heap = local;
Point pa[ 4 ] = { local, *heap };
return *heap;

Exercise 13.10: Define an Employee class that contains the employee's name and a unique employee identifier. Give the class a default constructor and a constructor that takes a string representing the employee's name. If the class needs a copy construc¬tor or assignment operator, implement those functions as well.
______________________________...
Among the fundamental operations a pointer supports are dereference and arrow. We can give our class these operations as follows:
class ScreenPtr { public:

Screen %26amp;operator*() { return *ptr-%26gt;sp; }
Screen *operator-%26gt;() { return ptr-%26gt;sp; }

ScrPtr *ptr; // points to use-counted ScrPtrclass
Exercise 14.20: In our sketch for the ScreenPtr class, we declared but did not define the assignment operator. Implement the ScreenPtr assignment operator.

How to disable "inline" keyword in C??
I am doing unit testing of some C code written in Unix. There is a inline keyword before so many functions in header file.
e.g.
static inline functionname(int arg)
(
// function body
}
I am compiling this code on borland compiler fo unit testing.
above function is called inside function under unittest. How do I remove significance on "inline" in one line from all other functions also.
How to disable "inline" keyword in C??
First of all, inline is not a reserved word in C. It is however a reserved word in C++.
Is the compiler you are using a C compiler or a C++ compiler?
If it is indeed a C++ compiler, you may find the following tutorial to be of use:http://dn.codegear.com/sv/print/23055
On the other hand, if it is a C compiler, more information on the compiler would be helpful.
Reply:I am not sure will it work in Borland compiler, but you can try to redefine "inline" keyword with a preprocessor.
#define inline
will remove all "inline" from your code before the compilation.

C++ Windows programming: Can't make this program run?

RegisterClassEx() fails because not all fields of wndclass are initialized - some contain garbage. It's a typical mistake that programmers make.

C++. How to use main() in a class? Is it possible?
Is it possible to use the pure object-oriented programming in C++?
Is it possible to redefine the entry point of a program to a member function?
e.g. the next code will not compile:
#include %26lt;cstdlib%26gt;
#include %26lt;iostream%26gt;
using namespace std;
class MyClass
{
public:
static int main(){
//This is the main function... it should be
//the entry point
system("PAUSE");
return EXIT_SUCCESS;
}
};
C++. How to use main() in a class? Is it possible?
Good question.
"Is it possible to redefine the entry point of a program to a member function?"
Yes, but it's not quite what you are expecting, and you really don't want to do something like that. A global main() function is required by the standard. In other words, if you wish to write standards compliant code, you should be using a global main, not a custom entry point. But to explain:
main() is not the entry point. Actually, a function called mainCRTStartup is. You're asking yourself now, I've never written a mainCRTStartup, and that's correct. It's part of the code supplied with the compiler. One part of the code is mainCRTStartup, which is the entry point. mainCRTStartup, among other things, calls main(). Don't believe me? Use the linker options to leave out the default libs; for VC++ it's /NODEFAULTLIB and for gcc linker it is -nodefaultlibs -nostdlib. You'll be forced to write mainCRTStartup yourself.
Now, technically you could change the entry point to MyClass::main()., but then you would have to reimplement the code in mainCRTStartup yourself. For what point?
"e.g. the next code will not compile:"
Just to nitpick, technically the code will compile, but it won't link to an executable, since you need the appropriate entry points defined in some linked in binary.
Aside, to correct answerer "the chip": "C++ isn't object-oriented, it's procedure-driven. The two programming concepts don't really mix."
C++ is object oriented. It has some very powerful generic programming syntax not present in other languages. Feel free to read Modern C++ Design http://www.amazon.com/Modern-C%2B%2B-Des... before complaining about C++ not being OO. Also, object-oriented and procedural programming mix just fine. Any reason they don't?
Reply:No, you can't do that in C++. It always looks for a global main function.
Reply:i dont think its possible to put main( ) inside any declared class.The main( ) fct is a fct declared inside the iostream library of c++, and u cannot use it inside any class,but it is used apart
Reply:C++ isn't object-oriented, it's procedure-driven. The two programming concepts don't really mix. If you want to do object oriented programming you need something like java.

Convert java coding program into c/c++.?
I don't understand your question. Are you asking someone to translate it for you, or asking whether it is easier to undertand in C/C++? C/C++ is easy to understand, especially if you leave appropriate comments.
Reply:Before you could convert it to c++ you would need to know what platform you are targetting, that is, MS Windows, UNIX, Linux, Apple, etc.
The reason for this is the different platforms offer different windowing systems. The thing that display the windows you are currently looking at. In the c++ standard, there is no mention of computer graphics, and therefore no standard way of displaying these windows.
Therefore, you would need to know what platform you are targetting, and also if using MS Windows, you need to know what framework you want to use. Some are Win32 API, MFC, OLE, .NET, etc. Then you will better able to know how to build the Graphical User Interface (GUI) like the JFrame, JOptionPane, JLabel, etc.
Converting the other non GUI code should be fairly easy.
P.S. The idea of allowing people to select the month, and then the day and year from a combo box was a very good idea. You should pursue that one.
To select the days to display for the month, you could set up what is called a lookup table. As there are only 4 varieties of days in month, eg 28 feb non leap year, 29 feb leap year, 30 and 31, you only need to 4 instances in this table. Then after finding the index of the combo box item that was selected, use this index to look into the lookup table that holds a link to the instance of 28, 29, 30, or 31 days.
The table could be easily set up as a 4 element array, each entry being another array of the numbers from 1-28, 29, etc. The value to index this table would be 0 for feb in non leap year, 1 for feb in leap year, 2 for 30 days, and 3 for 31 days.
You then update the combo box with the array of items that you just indexed.
Do the same thing for the years, etc, although you would probably need a bigger array for them, eg, 1973-3000 would be require a bigger array than 4 or 31 elements.
This way, you would not have to parse the integers, eg parseInt(...) as you are not checking for an errors, ie, a letter in the text instead of a number, which will produce a number of exceptions.
try
{
Integer.parseInt(dat.getText()...
}
catch (NumberFormatException ex)
{
// Error, a number was not input
// Inform user, reset fields, etc.
}
After looking at your code, I am going to make some changes, so you can remove the GUI stuff from the non GUI stuff, and therefore, hopefully make the transition from Java to c++ easier.
Changes:
(1) Added method checkParam() that does the checking you did in the action performed method.
(1.1) The code in ActionPerformed to reflect above change.
(2) Added the above try - catch clause.
(3) The method 'chkerr()' calls a new method to display the error, so as to seperate the GUI from the other.
(3.1) Updated chkerr() to reflect above, and call the method when an error occurs, instead of waiting until the end of the method to deal with the error. Just semantic changes.
The other thing to remember is that in c++ the 'string' class has a lower case s, not an upper case S like in Java :)
Here is the updated code. Starting with the class ExitListener, the code above that was not changed.

Function pointer - C++ code section?
I came across following section of code %26amp; it is working with a highly complex system.
Can someone provide some explanation on this like which constructor is being called %26amp; where parameter pCallback is being sent %26amp; what is the meaning of void(*)(void*)%26amp; a::afoo mean?
===================================
a.h
static void afoo ( void * );
a.cc
void a::afoo ( void * pCallback )
--------------------------------------...
file b.h
b ( void );
b (
void (* pStatsUpdate ) ( void * ),
void *
);
file c.cc
new b (
( void
(*) ( void * ) ) %26amp; a::afoo,
this );
===================================
Function pointer - C++ code section?
It does not look sensible to me. The retyped text probably contains some syntax error, For example,
a.h
static voidafoo ( void * );
should be
a.h
static void a::afoo (void*);
or it must be part of a class or namespace declartaion as
class a {
// ...
static void afoo (void*);
//...
};
or
namspace a
{
//...
static void afoo (void*);
//...
};
It is also important to know in which part of the code these declarations and / or defintions take place.
This faily complex structure is either generatated by some auto code generator software, or some programmers that do not like to make their minds clear when they do programming.
The expression void(*)(void*)%26amp; a::afoo means a pointer to any function which returns a void and takes a void * as its only argument such as
void f (void * vp)
{
//...
}
a::afoo class method or namespace function obeys this signature, and therefore, it is qualified to be cast to this type.
I think yet there is another mistype with the %26amp; in this part unless it means a pointer to a pointer to the function (and not the pointer to function itself).
Reply:void(*)(void*)----means a functin pointer, that takes a pointer as parameter and does not have a return value............
the use of %26amp; is the change in function will in turn effect the actual arguements.....
for that paarmeter pCallBack, i think it will return the value to the constructor in a.h, provided you mention its location...

Basic C syntax, assigning a value?
I am working with Borland C++ 5.02 compiling a C program to read an INI file with this function prototype:
extern const double readIniDouble( void *fp, const char *section, const char *name, const double defValue );
I can read the value with no problem with this code:
double test;
test = readIniDouble( iniFile, "ASection", "AName", 2 );
cprintf( "%e", test ); // Correctly writes the default value of '2'
The problem is that I need to get the value into a struct:
static struct settings tmp_set;
tmp_set.aSetting = readIniDouble( iniFile, "ASection", "AName", 2 );
cprintf( "%e", %26amp;tmp_set.aSetting ); // does not work
This compiles but prints an unexpected large number. If I use an ampersand or asterisk in front of tmp_set on the left side of the assignment (%26amp;tmp_set.aSetting = ... ) I get a compiler error 'Illegal use of floating point'.
What is the correct syntax to assign the return value of the iniReadDouble() function directly to the struct member?

don't print %26amp;tmp_set.aSetting, just tmp_set.aSetting. With the %26amp;, you're taking the memory address of that variable, not its value.

DeVille a/c?
My in-laws Cadillac DeVille a/c stopped working, and low refrigerant-no a/c came up on the message center. I took it to the shop I work for, checked the refrigerant level, and had about 100 psi static pressure. Just to be sure, I reclaimed, evacuated, and recharged the system, still had 100 psi. Jumped the low pressure switch, no change. Un-hooked the battery cable for 5 min, bang, the message disappeared and the a/c started working fine. Anyone have any idea what would cause the eatc to need a reset to begin with? A bad connection at the low pressure switch, or a switch starting to fail, maybe?
DeVille a/c?
Hi, Yes. What year is the car? If it is less than maybe 9 years, or so, the computer controls (everything in some way) I think you did the right thing by unhooking the batt. That resets, and starts from (zero). All you need is a wire thats not hooked, or wet,or dirty, or something to break contact, and you have to start from (zero) again. I still like the Model A Ford (They are east to figger out you know! Hope this helps?
Reply:Could've been anything like the other guy said, a surge in the system, even a hiccup could set it off. If checked all the connections wait and see what happens...
