I'm assuming you mean a console program?
You'll have to know the width of the screen, typically is is 80x25, but it can always be different.

You can't do a gotoxy function in pure C, you'll have...

You will have to know how a stack frame is implemented on your system. I don't know if it is the same for all (or most) x86 systems, but from looking at this article on wikipedia...

>> I was also under the impression that VB passed BSTR strings to C/C++.

You're right, but I just designed my function around the hex output that I got... I decided before I went to documentation...

Well, back when I used VB a lot, I know if I tried to use anything but a basic character, it would show up as a question mark--also, the function I have written here is to change an ASCII string into...

alright, I did this without the help of documentation or help forums, I just sorta, figured it out on my own--and hacked together some code to make it work, and I'm super proud, so bare with me:

Clearly he has duplicated Narue's answer,
however, I don't agree with your second point...
I see no problem with contributing something to a solved thread, especially if there's more than one way...

alright, just throwing it out there

okay wait, even though this thread is solved, if it's a string couldn't you use strlen? Or just int length = 0; while(length++,*myString++);?

lol, he's referring to the byte-order his operating system uses when storing data. say a 16 bit integer needs to be stored in memory by a program. It can either be stored in little endian format, or...

fix'd.
Know what the problem was?


Public Declare Function callback Lib "C:\c\dll\mydll" (ByVal cbAddress As Long)

The function in the DLL doesn't return a value, so it should have been

I've been able to design a front-end for a C DLL, calling the DLL functions from the VB program but I'm having trouble calling the VB functions from the C DLL. Maybe I should have put this in the C...

awesome, thanks

What's the main difference between while(){ } and do{ }while() loops? From looking at it, it looks like the former evaluates before it performs the iteration and the latter does the evaluation after...

not too late, thanks for the tip

okay I see,
and yeah I guess the phrasing was a bit loose... but with a char array,
you can define it char x[]="rawrawrawrawrawr"; or char *x="rawrawrawrawrawr"; and have it behave the same, no?...

I'm unsure of how declaring **x (a pointer to a pointer of x) is the same as declaring x[][] (a two-dimensional array of x's)... The theory I have is this:

int *x = {whatever}; (x is a pointer to...

> Well, according to me: Its the knowledge about language that counts rather than what tools/text editor you use.

yeah, good point.

Also, I may have to give Code::Blocks a try, it looks pretty...

why not? It is a forum... and I tried learning emacs but it got old quickly, I prefer using vim on *nix

yeah, I know it's definitely a no-no, I just thought it was kind of cool, being able to cheat the compiler. Get back at it, for all these years of yelling at me, and telling me how wrong I am. Take...

What editor/compiler does everyone use,
and,
what is your syntax highlighting like?

I'm using programmer's notepad 2, with a gcc win32 port...
with a stylish green-identifier, gray-text,...

wrap this in tags, with indents. And what do you mean you "want to match void getdata() and void stock()"?

#include<iostream>

using namespace std;

int main(){

int a;
int b;

asm("jmp c\n\t");

okay, thanks--and I figured out the scope pretty quickly, it's weird how if you

int z;
{
z=5;
}

then the z refers to the z outside the braces, but if you

int z;

Well, I don't know if this is what you would call an anonymous function, or "Lambda" function I guess, I haven't really gotten that far into languages that use them yet...
but, I am writing a...

oh, when I look at it, it says "c++vbfail.jpg".

and yeah, I know, I'm pretty fluent in VB but new in C++, I just wanted to see how people responded. Pretty awesomely, if you ask me.

ok but wait, wat's the diff? o i no, it's that vb can't use classes rite? not OOP? ic

ps. look at the filename of the attachment, of course it's a joke :)

hehe sorry I thought I was in gcc. My bad

I've tried everything, and I just can't get my program to compile in visual basic. Someone tell me what I'm doing wrong?

see attached image, are the includes in the wrong spot or WAT!??!?!

anyone know of a free ANSI lisp compiler for download?
I want to learn some lisp but I don't want to use REPL in emacs anymore... I want to write source code and compile it haha.

I already marked it as solved, but just letting you know I got it all working, and I understand all the code now--thanks for the help, I learned a lot more about classes.

awesome, thanks a lot for your help

well it works really well but there is some syntax here that I don't completely understand...
virtual void saveMessage(const char* pmsg) = 0;
virtual means that the child class will inherit this...

sounds perfect... how would I declare a pointer in the A class though?
Like, would I just go B &errorTarget;?
or would I use the * operator? The most I've really worked with pointers so far is in...

In my example code above,
if I called something.someObject[2].setErrorMessage("BIG ERRAR!");,
and then in A::setErrorMessage(char*), used the this operator, would "this" refer only to someObject[2]...

hey thanks, I wondered how others did it.
Also, flame wars might be appropriate considering your avatar.

Also, back to the original problem in the thread,
Not everybody is going to have the same...

in your first post, you need to end the class with a ; after the closing brace

class name {
...
};

you would access it by creating an instance of the class in a declaration,

class clName{...

lol oh noz progamming flame warz

lol what's bad about it? I put it in that order because class A has to be known before I can declare an object of type A in class B, the classes need to interact with each other, that is my problem....

but there is a need for class A to be in class B

it's a syntax error, the compiler will tell you what line it's having a problem with. Take that line of code, or the procedure that line of code is in, wrap it in [ code=cpp] [ /code] tags (without...
