GetImage func give up this parameters :
getimage(int left,int top,int right,int bottom,void far *bitmap);
so Getimage save a rectangle shape on *bitmap.
Is it possible that we can save the other shapes except rectangle? circle,or star, or...
Consider I have a rectangle like this:
Point p1(100,100);
Point p2(300,200);
Graph_lib::Rectangle r(p1,p2);
And also I have a function that takes a rectangle and returns a Point of that, say, top-left corner of that rectangle. For example:
Point N(Graph_lib::Rectangle R1);
My question is that, first, how to send that Rectangle r(p1,p2) to the Point N(Graph_lib::Rectangle R1) function? And then, how to return a Point from that function?
My IDE is visual studio 2012.
I'm trying to find the fastest method to find whether or not two rectangles intersect in an effort to streamline my code. I've built this function into a rectangle class I created below.
struct rectangle{
rectangle() :X1(0), Y1(0), X2(0), Y2(0) {};
rectangle(int X1, int Y1, int X2, int Y2)
:X1(X1), Y1(Y1), X2(X2), Y2(Y2) {};

So basically I have to write a C program that, when opening the html file in a browser, looks essentially like this: (Size, position, color of the shapes doesn't matter so long as I have one of each shape and the box surrounding them. Words up top dont matter either.)
This is what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#define FILENAME ("A4P1.html")
[code]....
Anyways i can get the individual shapes, but I don't know how to get all the shapes to appear at once..
i have to make an application called " paint " in c++ . It should facilitate user to draw different shapes using a mouse. Now the biggest hurdle i am facing is the usage of mouse .. what is the header file for usage of mouse ? i am using visual studio 2010 . the syntax is creating problems ..

View 1 Replies View RelatedI am trying to develop a GUI using MFC, but I am having trouble using CFiledialog to save a file. The problem is, the file is not getting saved to the folder when I use the CFiledialog. Below is the code I am using.
Code:
CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)

After the file dialog opens up, I enter the name of the file and select OK button. But the file does not show up in the directory I am saving to.
This time I need to generate random shapes (circles, rectangles, squares, and ellipses) with random attributes with C, to html.
I am able to create specific shapes with random attributes, but I am unsure how to have the function create a random shape...
Also, the function "box" is meant to create a black border around the shapes. It does this, but I do not know how to make it so that the other shapes do not show up along the lines of this "box."
I guess it appears that certain shapes are "layered" over top of others? ie. My circles/ellipses always show up on top of the rects/squares/box.Currently I have this:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NO_SHAPES 10
#define X_RANGE 797

I have a function (name Callback), with take some parameter( name Arg). I want to create it before, pass it to other class ( class B). And in class B, call the Callback function with Arg paramater. It's something like this:
class A {
void A::doSomething(int a, bool b){//dosomething};
void A::setCallback(B b) {//I don't know how to do this};
[Code].....
How can i do this? And what happen with I want B can get more type of callback function, which mean I don't know the type of Callback's paramater?
This error keeps coming.

How would this look like in C? Develop an application to calculate the area and perimeter of geometric shapes. First the user is asked to enter a letter representing the shape. We use C for circle, R for rectangle and S for square. After the user chooses the shape, the program prompts for the appropriate dimensions of the shape accordingly.
For instance, if the user has chosen a square, the program will ask for a side. If it's a circle, the program will ask for radius. If it's a rectangle, it will ask for length and width. Upon receiving the appropriate dimensions, the program will calculate the area and the perimeter of the requested shape and print it on the screen. And again, the code will ask for another letter. If the user enters 'Q' the program terminates.
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >S
Please enter the side of the square > 8
The area is 64 and the perimeter is 32
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >R
Please enter the width of the rectangle > 5
Please enter the length of the rectangle > 7
The area is 35 and the perimeter is 24
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >Q
I installed FLTK 1.3.X from [URL] on my visual studio 2012 compiler and use PPP book for C++ programming [URL]. My problem is about filling a Shape in.
Code:

Simple_window win(Point(100,100), 1000, 600, "Binary_tree");
Graph_lib::Circle c(Point(200,200),50);
c.set_color(Color::red);

When I run the program, All three Shapes are drawn on window but only the Rectangle is filled in! Why? set_color works for the three and apparently the set_fill_color is defined for all Shapes and it too should work but why it doesn't for Circle and Ellipse?

how to use 3 variables to represent a rectangle in a grid instead of using 4. The traditional way is to use (x,y) (x2,y2). I propose using (x,l,h).In the traditional way as you probably know, (x,y) is the left op most corner, and (x2,y2) is the bottom right most corner. In the way I am proposing X is the left side, l is the length of the top side, and also the length of the bottom. 'h' is the height of the left and right. I think it's obvious how these three can define a rectangle same as the four.

I am not sure how to format it because it is only drawing one and it does not move across the screen. I thought this section of code would work and loop through each object and make each one move but it does not.

// subtracting the area of two circles from a rectangle

The problem says:
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?
