Ok I am building a GUI Framework, where there is a Widget class,
which can both have mother widgets and be a mother widget.

When some event happens, the widget receives a message, in the form of...

Too time consuming. I would rather not do it at all then

And about the code snippet, if I create an instance of Mother,
and call HandleMessage<10> it would print "It works!\n".

But if I call...

I would recommend a disassembler, but requires you to know assembly.

Well it is an integer, compared to a list of integers.

Hi I have a problem, I hope you can help me with.

I have a number, which I need to compare to some values.

I do not wish to go through all the values, and compare them individually, as I there...

OK last try

class TestA;
#ifndef __TESTA_H
#define __TESTA_H

#include <stdio.h>
#include "testB.h"

class TestA {

Are you sure you want to have a pointer of the other class in them both?

You should always include the header when you want to use it's class to avoid multiple inclusion add the following code.


#ifdef TESTB_H
#define TESTB_H

//class declaration

#endif

Include testA.h in testB.h if you want it to have a pointer to a testA object

put the declaration in the header file and the definition in the other


//declaration
class foo
{
void bar();
};

//definition

Possibly the fact that struct keyword mostly is used for containers?

Well come to think about it I don't know why I wanted to do it.
Maybe I am just tired.

Thank you for answering the questions I will just assume it is ok to make a main class.

I didn't think non heap variables could be said to be allocated because they are allocated by the OS at...

Yes I was assuming a destructor was implemented but my question still applies should I allocate all my resources in classes?

As for question number two here is an example of what I mean


int...

I have been testing a C++ based SDK and now i have a few questions for you that i hope you will answer
.

1. When passing objects between each other is it preffered to use references if not what...

Thank You!

this is what I've got.
There are some problems and you can't replace a function but I can handle that myself


class msghandler
{
public:
void HandleMessage(WNDPROC func,...

The problem is that it is the windows API we are talking about and I can't have a predefined function for every windows message.

I was thinking something like obtaining a function pointer and the...

Yes but in an automated way so I can add functions at runtime and make it have a value.

I know I could do this with a loop and an if statement but it would be optimal if could check if the message...

Hi and sorry for the inconvenience

I am trying to make an interface where a function is run given a number(windows API).

I want a default function to be run if it hasn't been overwritten by the...

I don't think you can't assign values to functions/methods.

I don't know what you want to do but as I see it you use the assignment as a way to make the method do nothing until you find out how to...

Just use <iostream> there is nearly no syntax difference and your program might not compile on all compilers

Use this

ofstream out;
out.open("\\reg.txt");

Ok i have been thinking.

Would it be possible to intercept the messages sent to the desktop window?

Like after we are done painting the screen go to this program.

The one and only "Charles Petzold Programming Windows"

Try this.


SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), BACKGROUND_RED BACKGROUND_INTENSITY);


You can change RED to GREEN or BLUE and BACKGROUND to FOREGROUND.

If you want to...

What he meant(i think) is that you could do this.



ShellExecute(0, 0, "<program to open program with>", "<file to open>", 0, SW_MAXIMIZE);



This is ofcourse not optimal but it can be used...

Hi.

I am making an application that will use the screen and do something with it(live).

My problem is that when i do that i get the previous screen made by my program last time i updated the...

When you double click the *.pps file does it then open?

If it does try checking what app is used to open *.pps files.

Thank you everyone.

It worked when i used.


SetWindowText(GetDlgItem(hWnd, 112), buffer);



It ignores newlines but i think i can handle that.

Hi i am trying to make a notepad like program.

The problem is that when i try to display some text nothing happens.
If someone could help me i would really appreciate it.

The function call:
...

thank you everyone

for misunderstanding the concepts of classes i thought that it was the core of an optimal program (like code at bottom of post) is it really only to reuse code?

class someClass
{
public:
...

i am sorry

ok thank you.

hi i was wondering how much i should use classes in C++.
Should i use it as much as possible?
