Re: cin question from newbie

30-Aug-04 12:07

cin should do this for you ? Have you tried using a std::string instead of a char array ?

#include <string>
#include <iostream>

using std::cin;
using std::string;
using std:cout;

int main()
{
cout << "type it in";
string s;
cin >> s;
cout << "You entered : " << s;
}

That's from memory by a guy whose C++ is VERY rusty. But I think it should work.

This worked for me, unless I misunderstood your problem:

void main( void )
{
    char m[20];
    int a, b;
 
    cout << "Char ";
    cin >> m;
 
    cout << "Int a ";
    cin >> a;
 
    cout << "Int b ";
    cin >> b;
 
    cout << "Char " << m << endl;
    cout << "Int a " << a << endl;
    cout << "Int b " << b << endl;
}

Hi!

I'm going nuts here! Spent a whole week building three huge classes and now got a bright idea...What if I was to organise my classes, def in headers, say cls1.h cls2.h cls3.h (by the by got implementation files .cpp's D'Oh! | :doh:

),
into a neat monster class clsMonster.h!

If you didn't understand what happened just now dont worry I still cant figure out why I even had the thought in the first place!

The thing is I got these 3 classes that logicaly are a part of a thing that can be a big class on its own. I started developing them separately since they are big but now feel that they would be neater if there was one class containing them sub classes (just jaming every member in clsMonster would be overkill and give me 2000+ lines to debug in one pile! OMG | :OMG:

).

I made a new header, defined the big class but now need to access the members of sub classes from main() thru the big class.

Problem: Cant figure out the damn syntax of accessing the members of sub classes.

eg.

....

#include "cls1_H.h"
#include "cls2_H.h"
#include "cls3_H.h"

class Player
{
blah blah
};

.....

#include "Player_H.h"

main()
{

Player myChar;

myChar.blah blah(); // this would access members of Player
}

BUT HOW DO I ACCESS THE HEADERS INCLUDED IN Player.h???

Is there an other way to do this! (main concern - neat groups!!!)

If anyone is on this particular line right now, THANKS FOR YOUR TIME!

Sorry but your question makes no-sense at all.

Can you give an example of what is in cls1_H.h that you are trying to access. The blah blah in Player is a little confusing. A real example would be more helpful to diagnose your issues.

First problem. Try to design your structure so your classes are lightweight.

That's NOT neat, it's a 'monster', a maintenance nightmare.

Figured the whole thing out. By the way classes are so big due to enums, got lots of them!!!

Generate/edit files

Generate files
How can we generate files.
for example if I want to make an exe file that generate another exe file.

and if i make a program and put an edit box, and when i write something in the edit box, and click generate. the value in the edit box will be edited to the generated exe files

or

if i have an exe file that have an (m_value) Cstring
and make another file to edit/change (m_value) Cstring

is it possible?

thanks alot

You've got one. It's called a compiler Smile | :)

Your compiler does this also. You can take a string and shove it into a file easy enough, it's 'generating' an exe that is the job.

You need to define a process to do this, your two processes need to communicate and cooperate to achieve this.

you misunderstod me
I know that the compiler make the exe programs

but I mean to make a program let's call it "one.exe" and in this program are some edit box, when i write some values, i want it to be saved in other exe file with these values... i hope i explained it better this time : )

thanks alot

I know what you want, it just sounds wierd. Why do you want to do this ? Is it to patch another program, or is it to hack it ? Either way, it can be done, so long as you're willing to sit with a hex editor and work out exactly at what position you need to insert your new value.

I am having problems running .exe files. I am trying to run a .exe when the user clicks on a button. Could anybody please tell me the exact code which i could write in the Message Handler Function.

ShellExecute or CreateProcess(Ex)
Have a look at MSDN or Platform SDK.

Don't try it, just do it! Wink | ;-)

if you are using regular win32 api, i assume you already have a message handler for the parent window no?

if so, then you need to add a WM_COMMAND case
and test if the HIWORD() of the lParam is == BN_CLICKED and if (HWND) lParam == YourButtons_hWnd

if so then run the app

now if you are using MFC then do this
goto the dialog designer, double click on your button

and insert the code to run your app

Use either of the following API -
1> ShellExecute
2> CreateProcess

Check on msdn.microsoft.com for further details on these API

Hope this helps

how do you start to write an application or how do you just write one, the source code that is, and does any one have a copy that I can look at.

It really depends on what type of application you want. MFC (Microsoft Foundation Classes), ATL (Active Template Library), Console, WTL (Windows Template Libray), and there are different types of each kind too, dialog based, document/view, etc...

The simplest way is to start up Visual Studio and then do a File->new and create a new project of the type you want. If you can give abit more information like "I want a program that is like notepad" or "I want to make a command line program" that would help define how you start to make it.

I want an application that will allow me to chose any text, file folder or line I type in to be encrypted and then be able to pick an ecryption program off my choice

It soulds like you might want something graphical to make it easy to use. I personally like to use dialog based applications for things like this. So what I would suggest is that you start an MFC project in visual Studio and make it dialog based. Then you can add the buttons and textboxes to do the searching for files, or folders and then have another button to start up your encryption program. That should probably be stored as a configuration setting in either the register or some external file, ini or xml. You should probably also put on the standard menu on the dialog and add things like options, and exit.

It might be simpler for you to have separate input sections on the dialog for text files, folders and freely entered text. This way itwill not confuse the person using the software.
