I have simple question. I have long code in my .cpp file with classes functions etc. I would like to divide it into separate cpp and .h files. What are rules governing the stuffing? Any good tutorial/example? Cheers :)
I think alot of people go for fun and some like me are holding back due to lack of libraries fo Python3. I'm still with my 2.5
Anyway, just for wxpython users, there are new binaries for 2.6 and obviously all other except 3, fixing the wxpython problems for manifest once Scru pointed out :)
if you produce simple example it will help alot including me. I believe it is easier to make exe with C/C++ than python. So if it is that easier I would prefer it!
After pondering and wondering, I have decided to go for wxWidgets. Here is my first trial application. After running a test app from zetcode.com in my Code::Blocks & wxWidgets and I confirmed that it is fine! Then I tried to write my own app as shown below but I ran errors. Please correct me wher I have gone wrong, and any suggestion in the code. I'm just starting with wxWidgets Cheers :)
#include <wx/wx.h>
class MyApp : public wxApp
{
virtual bool OnInit();
};
class MyFrame : public wxFrame
{
public:
MyFrame(const wxString& title);
};
IMPLEMENT_APP(MyApp);
bool MyApp::OnInit()
{
wxFrame *newFrame = new wxFrame(wxT("Hello Mary!"));
newFrame->Show();
return true;
}
MyFrame::MyFrame(const wxString& title)
: wxFrame(NULL, wxID_ANY, title, wxDefaultPosition, wxSize(250, 150))
{
Centre();
}

It have been easier for me to "Hard code" than using designers. You have complete control over the code and can do any change and of course code re-use :)
I haven't have a choice yet. I want to go for wxWidgets due to wxpython background. Before that I want to test The rest. How do you see guys, should I just start with wxWidgets and shut eyes on others? :)
I wonder if there are GTK+ users or my question isn't well framed! To try elaborate, How do I need to try GTK+ with C++. What makes difference between GTK+ and gtkmm? How do I use it with CodeBlocks?
I'm trying wxWidgets right now, I will try GTK+ next then QT. But I don't know anything about how to go about GTK!
I'm trying GUI Library to see what fits me. I want to try GTK+ too. But I don't know where to start. At GTK+ site I took a look at C++ bindings http://www.gtkmm.org/ and found * glibmm 2.20 (stable) * gtkmm 2.16 (stable) * libgnomecanvasmm (stable) * gconfmm (stable) * libgdamm * libpanelappletmm 2.6 (unstable) * gtkmm-hello 2.4 What is what? Which is which?? :)
I have two files and I would like to call addition function from functions.cpp in main.cpp. But I get error:
In function `int main()': error: `addition' has both `extern' and initializer error: initializer expression list treated as compound expression warning: left-hand operand of comma has no effect error: `addition' cannot be used as a function| ||=== Build finished: 3 errors, 1 warnings ===|
Here are files main.cpp
#include <iostream>
using namespace std;
int main()
{
int summation;
int a, b;
cout <<"Please Enter the two digits to add"<<endl;
cin>>a>>b;
//add external f(x) from function.cpp
extern int addition(a, b);
summation = addition(a, b);
cout<<"The sum is "<<summation;
return 0;
}
functions.cpp
int addition(int a, int b)
{
int sum;
sum = a+b;
return(sum);
}
partitions are there but one cannot get opened, and another get opened and you see no files! Very strange, I almost every time invoke chkdsk with /r and /f but guess what, the same problem.
Please help me guys. My Disk have corrupted and chkdsk have failed to repair although it have detected the corruption. It is external HDD and I don't know if there is any tool I can use apart chkdsk. Both partition in the drive are corrupt and they have my very important Data.
I hope to hear from you guys I have attached the screenshots. Thanks alot!
Maybe wxWidgets as it matches with your avatar :P ...
Hahaha! That avatar represent wxpython, the python bindings for wxWidgets. I will try both, but starting with wxWidgets, since it have been my default in python.
Just curious question(though I will post it in python in due time) have also pyQT went to LGPL?
Thanks guys, I love your suggestions. One trouble I had with QT and its pyQT was licencing issues. Someone have said I have to link shared library and I will be fine, but that is hard cookie to a little babe :) I'm still learning console apps and haven't done much with Linking anything, so can anyone help me with grain of salt!
Hello all, I'm trying to link two files but I get error "multiple definition of `funny_words()' " I don't know what to do, as I'm new to C++. I'm reading PROGRAMMING IN C++ by P.B. Mahapatra and the topic is PREPROCESSOR. I have to learn how to Link headers, and cpp files using # include. My first trial with cpp have failed.
Soo much words, but here are two source codes: 1. main.cpp
#include <iostream>
#include "hello.cpp"
using namespace std;
//declare the class
class triangle{
//only visiblein class, invisible outside
private:
int base;
int height;
int area;
//visible both in and outta class
public:
int triangle_area();
int get_values();
};
int triangle::triangle_area()
{
area = 0.5*base*height;
return(area);
}
int triangle::get_values()
{
//prompt for triangle base
cout<<"Please Enter the value of the triangle base"<<endl;
cin>>base;
//prompt for triangle height
cout<<"Please Enter the value of the triangle height"<<endl;
cin>>height;
}
int main()
{
class triangle ABC;
ABC.get_values();
int area;
area = ABC.triangle_area();
cout<<"The area of Triangle is "<<area <<endl;
funny_words();
return 0;
}
2. hello.cpp
#include <iostream>
#include <cmath>
#define GEQUAL >=
using namespace std;
//function to display some funny words
int funny_words()
{
int iq_test;
cout<<"What is your IQ ?"<<endl;
cin>>iq_test;
if (iq_test GEQUAL 50)
cout<<"You got it! Excellent!"<<endl;
else
cout<<"Sorry! you need to pray more for wisdom!"<<endl;
}
Ok I have made a progress I have successful embeded my js code in php. The problem is, the list doesn't load! I wonder if one can see the error I have made!
Note: I forgot to say that my index file is at "/elijah/index.php" and the player is at "/elijah/player"
the code I have embedded in my index.php
<?php
echo "<script language='javascript' src='/elijah/player/swfobject.js'> </script> \n ";
echo "<div id='flashPlayer'> \n ";
echo " This text will be replaced by the flash music player.\n ";
echo "</div>\n";
echo "<script language='javascript'>\n ";
echo " var so = new SWFObject('/elijah/player/playerMultipleList.swf', 'mymovie', '295', '200', '7', '#FFFFFF')\n ";
echo " so.addVariable('autoPlay','no')\n ";
echo " so.addVariable('playlistPath','/elijah/player/playlist.xml')\n ";
echo " so.write('flashPlayer')\n ";
echo "</script> \n ";
?>
Here is their sample code to use with player and it works when the file is in the same folder. I know almost nothing about javascripting Thanks!

Great SCRU, I ask because I use wxpython in Python (remember me?). I have been a little busy and disappeared for a while! I prefer wxpython in Python but any of two (QT or wxWidgets) is ok for me, provided it fulfills what I need. Your conribution is fine.
Here is my Question about LGPL and QT, does it allow me to use it commercially (If I wish to) with no restriction like previous? Then here is another question, is there free book about QT 4.5?
Just a curious Question. What do you prefer, QT or wxWidgets? How do compare the two in terms of: 1. Nativity 2. Easiness to learn 3. Documentation 4. Weight (The size in MB) 5. Licencing 6. Any other factor(AOF)
Hello all, I have been teaching myself PHP through others writting; so bear with me if you find something foolish.
Having said so, I want to make a simple Music library with MySQL/PHP. I have made this very simple Login form as shown below. I want after someone successful login be redirected where he can populate things in Library. The he should be able to see it via another PHP file. Here are my Questions: 1. How do I redirect a page after successful login? 2. How do I make a dynamic table that I can alter its cells anytime? I mean when one adds his music the PHP file should print the table with cells full of all info. 3. Supplemently, can one recommend tutorial that can help me to achieve what I have said?
Thanks all :)

Thanks all. Paul, I also enjoyed the same tutorial too. The only thing I wanted to know if there is anything I need to know before attempting writting my Own chat program. According to Murtan, peer to peer is easy. What if I want to use yahoo server or msan or etc or my own server how can this be accomplished?
I will advice you to do what I always call "hard coding". It is coding from scratch. This have these advantages: 1. You make exactly what you want 2. You know how things works 3. You can reuse some parts of code 4. Etc.
Having said so, here are some editors/IDE for mainly PHP but will do also HTML
I have the page and the main page doesn't get to bottom. In short it doesn't fit up. Take the code and see what I mean. If you don't know PHP just replace it with <p> Garbage words</p>

I have been in some tutorials for socket Module. It is very interesting. I want to know what I need to Know to make simple peer to peer/Client server Chat software but I'm new to Network, so anything that will help me put things together?
I'm beginner in PHP, and for long have been doing my site in XHTML. Now I want to make a News box and have made PHP code for that function as shown below:
<div id="mainarea" style="padding:10;">
<?php
include("$paths/include/inc.main.php");
$words = "Try again";
$class = "pop_window";
//the code are in the below file
include("$paths/include/inc.container.php");
pop_boxes($words, $class);
?>
</div>
and the class in CSS is only configure to have red background as test enviroment, that is:
.pop_window{
border:1px;
background-color:red;
}
It strangely prints "Try again" with no formatting and no <div> box. What is wrong?
Thanks for your help!
Hi All, Here is my Index code. How can I make footer be at the bottom of other div. In css I floated to left the leftbar and to right the main contents. The header is fine but footer comes just below main content instead of being at bottom of all divs. Please help me get it down
XAMPP Installs everything. Don't choose what to install unless you are sure. Also XAMPP configures stuffs that would be weird for Newbie to do. So I would say uninstall it and re-install it as full package :)
Yeah, that error is obvious, but I failed to see it. Thanks. It is that I'm refactoring my old HTML code to incorporate PHP. However, My working folder in XAMPP ("/project/elijah/elijah.css") will not be valid when kept on server where path will be something like "/elijah.css". So I want to use path to avoid changing things in file, which is tedious work :)
foreach($array as $value) simply means, for every element in the array, assign its value to $value. foreach($array as $key => $value) assigns the index of the array to $key and value of that index to $value. :S I hope I am not confusing you! This is almost similar to for loop.
for($i=0;$i<count($array);$i++) {
echo "Key is".$i."Value is".$array[$i];
}
//is same as
foreach($array as $key =>$value) {
echo "Key is".$key."Value is".$value;
}
