try substituting <cstdlib> in place of <stdlib.h>

the code should be ANSI standard code to work on all compilers, and i DONT see any un-ANSI code! it should work on others, i have compiled DevC++ projects on MSVC++ Before without any problems

They only take up minute disk space and minimal ram on the html docs! You can always NOT provide a file, then nothing is drawn...

however if you want to create an object dynamically the new keyword / operator will call the constructor for the object, malloc wont! I have found more uses for new than malloc()...

or in full "std::vector", but there is still a danger that the struct name will cause errors. Easy just to do



namespace my_vector
{
struct vector // might as well class it
{

Can you explain further and provide details? Is the image on a window? CursorPos sounds like a console function to me...

Seeing as this thread is about timesaving what about inheritance? Its a good time saver especially for the masses intent on game creation.

Say you make a class such as


class CBASE_ENTITY
{...

I would also recommend DevC++, also DJGPP is useful if you want to program old VGA graphics.

Another way might be to define two classes with everything private (-constructors) and put the other classes functions as friends? the use of the static keyword could help as static fields dont...

not sure what is wrong there! However this code (untested) should work


#include <iostream> // std::cout
#include <string> // std::string
#include <cstdlib> // system

template <class t>...

DevC++ doesnt have graphics.h with it, its a borland extension. iostream.h should work if not try #include <iostream> without the .h

I thought <string.h> was part of the old c++ standard?

Where is the original thread. I might be able to have a look...

Lost times of how many times i have said this (it is posted 3 or 4 times ABOVE people!) but just to refresh...

THE MODE 13H CODE USES 16 BIT ASSEMBLY COMMANDS (16 bit interrupts is the problem)

DevC++ using mingw32 compiler. I think its the other way round as most MS users I have seen have got all sorts of auto-generated things to adjust the code! The brush issue should work as...

If you must use char * (c-style) strings then define them as

char *string1;
char *string2;

string1 = (char*) new char[length + 1]; // allocate memory for a string of a given length. the + 1 is...

std::string also works well

ie


std::string str1 = "string 1 goes here";
std::string str2 = "string 2 goes here";

str1 += str2; // add str2 to str1

median of a matrix? what is that? do you mean determinant? the fstream tutorial on the c/c++ tutorials forum will help with file IO.

search the code snippets. There are many examples there. strcmp is probably being passed / is returning invalid data. If you want strings why not use the string class?

also strcmp needs const char...

strcmp parameters are invalid like the compiler says! I would convert to using the std::string class found in <string> as it is much easier to use and has most of its operators overloaded so you can...

You could investigate DirectX graphics. It really isnt hard as long as you error check all the way, otherwise it starts getting frustrating. Or even easier try OpenGL

paolo have you tried EXPORTING / SAVING the sheet as a txt? And saying yes to something you say you dont know what it is (vb) in the next sentence is a bit worrying... ffrosk you cant complain really...

DONT use 10h graphics. Im assuming you have

mov ax, 0x13 or whatever
int 10h

This WONT work in dev C++ as it is a 32 bit compiler. You need to use a 16 bit compiler such as DJGPP! Or get a...

There are both these solutions in the code snippets library!

that makes no sense! Do you mean translate The EXCEL VB functions?

FireNet a good way to benchmark using the tutorial you just wrote would be to time a complete screen fill of pixels followed by some lines. Make it complex enough to differentiate between computer...

UNLESS you are compiling in 16 bit you CANNOT initialise a pointer to base VGA. Base VGA also is NOT 0xA000 in VBE systems (for 32bit ) as it varies and you need to get a pointer to it using asm...

The question implies you want the EXCEL functions to be written in a txt file --> which doesnt really make sense. It seems like you are after code to parse an EXCEL data file of some sort into...

A basic idea would be

1) Blit the blurred picture
2) Define a rectangle around the mouse co-ords (clipped to the blurred pic too!)
3) Blit the clear portion in the rectangle

A Win32 Text editor can be done with little effort indeed. Not much coding needed as long as you can get a window up and fill it with a menu + edit control (add a status bar as well if you like....)...

Its pretty much been coded FOR YOU!


int a[] = {5, 8, 4, 1, 7}, b[] = {12, 3, 15, 6, 23, 1, 2}; // lists declared
int sizeA = sizeof(a)/sizeof(int), sizeB = sizeof(b)/sizeof(int); // list sizes...

that happens a lot - you will need to design a method to eliminate the possability of entering a character! the isdigit() function from <cctype> should help. :)

that doesnt sound right! For 2 complex numbers

(a+bi) + (c+di) = z (z is the result)

real(z) = a+c
im(z) = b+d

So why do you want to add the real of one complex number to a different...

as jwenting said you CANT increase the size of an array, you have to make a seperate bigger one and copy, or use a linked list / vector solution. No need to x2 post! :)

Spotted a few errors (although i accept it is work in progress :) ): main should be declared as int main NOT void main....
...GraphMode is undefined as the previous ; finishes the statement (change...

you might want to use Win32 Lib functions or even better -> assembly language. Embed it in C++ inline for an easy ride, or make a 16 bit asm program, it is an easy way to read ports.

again: it is the function causing the error. invalid values are the MOST common cause for it to QUIT WITHOUT making a MS Windows error box. New versions have probably disguised the error and made the...

whilst we are on the subject of structures.....

I have only experienced this TWICE in all my programming years....


struct var

unsigned int a, b, c, d, e, f, g;
unsigned char h,...
