if there is a way to make Visual Studios step into a function while I am debugging.. I am trying to see the value of a certain int and making sure it is what I need it to be.. but whenever I use step into visual studios just skips right over the function and it does all the calculations..
View 4 RepliesWhere can I see my program execution step by step? I want to see the changes every line of code do, line by line.

For whatever reason, the program has got a bug. And I want to know what is going on within the SDK, how do I include the SDK source in Visual Studio 2010?
I have a doubt and I have two vectors to a function.
A vector is (int *, const int) and the other is (string *, const int) and want to spend the two vectors and unite in a single function
A vector is passed to a function, but spending two vectors and join I cannot find the turn.
try (int *, const int, string *, const int)
But only understands the former as I do
I know how to define a shape (here, a rectangle) and attach it to a window in C++ as follows:
Code:
#include <Simple_window.h>
void cir() { Circle c(Point(100,100),50); }
int main() {
Simple_window win(Point(100,100),600,400, "test");
[Code] ....
But how to define a shape (say a circle by that cir() function which is) outside of the main() function that is how to create a circle inside of the cir() function and it returns that circle when I called it in my main() function so that I can attach it on the window win to be visible?
My assignment is to create a C++ Program to find the sine of a number without any library other than iostream by using Taylor Series:
sin (x) = (x/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) ...... (x^n/n!).
Here is what i have done till now:
#include <iostream>
double fact (int f); //declaration of factorial function
double power(double x, int y); //declaration of power function
double sin(int x); //declaration of sine function
//double cos(int x); //declaration of cosine function
//double tan(int x); //declaration of tangent function

I need to develop a tool to compare geometric structure of point cloud from scanned objects with their CAD model. The CAD model is stored in step file. So how could I extract geometric information from step file? I am totally new for CAD.
View 6 Replies View RelatedWhen I use vectory.push_back(obj), if the length is out of reserved bound, it will deallocate the whole vector and reallocate a big piece of memory. From my understanding I think c++ only allocates 1 more place for the new obj. This is quite inefficient. Is there a way to set the step length whenever the size is out of bound? e.g. 50 more spaces.

void myKeyboardFunction(unsigned char key, int x, int y) {
switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.
I am trying to make an add-on to IE. This add-on doesn't have any tool bar or any UI.
I am just taking the details of currently loaded HTML page. Basically it is for manipulating one dialog box. I want to get access to the DOM COM interfaces of the dialog box.
Since it doesn't have any button I didn't impliment IOleCommandTarget. I implemented only IObjectWithSIte.
My RGS file contain following in addition to my COM related entries
HKLM
{
NoRemove SOFTWARE
{
NoRemove Microsoft

But I couldn't see my add-on working or even not loading to IE.
I have code (found long time ago, ~2001) to make videos from OpenGL rendering in my view class. In my OnDraw() function I call the function SaveAsAvi(). This works as intended until I have 255 frames in the movie I am trying to make. After that, Windows Media Player claims it cannot play the file. VirtualDub claims the avi contains Palette Changes and shows the correct number of frames (>255) but all frames past 255 are the same and equal to the last frame.
Memory overflow? Need to free m_pixels sometime somewhere?
Code:
void C***View::SaveAsAvi() {
C***Doc* pDoc = GetDocument();
if (pDoc->m_avi_status == -1)// initialize AVI stuff {
KillTimer(1);
// allocate space for the pixel info

I'm developing a software for Windows using MSVC 2010. My employer sent me 2 png files: 16x16 and 32x32 for the icons.
What I would like to do is to use them as a MSVC icon resource and don't use any code hacks. In the past all I had was an ico file and I just included it in the resource (rc) file for Visual Studio and that was it.
Now my question is: how do I make one ico file out of those 2 png files that will be accepted by MSVC? Is there a tool (preferably free) for it or some online service?
Here is my code for a simple game. paste it and try it.
#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
using namespace std;
int main (void) {
stringg[4],
[code]...
What they do (enter 4 actions)?
";
for (int ai = 0; ai < 4; ai++)
getline(cin, a[ai]);
cout << "
Where is happening (enter 4 locations)?
";
for (int li = 0; li < 4; li++)
getline(cin, l[li]);
for (int c = 0; c < 4; c++)
cout << g[rand() % 4] << " and " << b[rand() % 4] << " are " << a[rand() % 4] << " from a " << l[rand() % 4] << endl;
return (0);
}
At the end in the 4 lines some of the names, actions and locations repeat. How do I make them to not repeat and use every name that you will enter? do I need random_shuffle? How can I integrate it in my code?
Im suppose to make a "poor mans" variation to the Sort function built into unix. The program is suppose to read in a file and sort the contents of the file. So its a variation of the Unix Sort feature. I have remade the readLine function we were provided so that it doesnt use fgets. where to go from here, Not sure on how to make a sort function. Here are the reqirements of the program:
Code:
• Re-implement the readLine() function so that it no longer makes use of fgets(). Instead,
process the input on a given line character-by-character.
• Provide code which will create a data structure similar to argv to hold all of the words to be sorted. Use malloc() to ensure that each entry has just the required number of bytes needed to store the words. The final entry in your array should be the NULL pointer.
• Implement a sort() function which will rearrange the words in sorted order. To swap two words in your array, note that only a pair of pointers need to move. The strings themselves, once established, will never move. Heres what i have:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LINES 1000 /* maximum number of reminders */
#define WORD_LENGTH 10 /* max length of reminder message */

I will post the entire code at the bottom. Its running fine right now but This part in the menu function I need to make as a separate function. My problem is when I make it into a function by itself I have to declare and initialize the grades A,B,C,D,F how can I do that when I can't make them equal 0 because it has to keep track of how many of each letter grade.
Code:
//Count letter grade
if(ave >= 90)
++A;
else if (ave >= 80)
++B;
else if (ave >= 70)
++C;
else if (ave >= 60)
++D;
}

I would like to know if there is a way to make a function non overloadable. My idea is to keep it private in the class so that it will be impossible to overload the function in a derived class.
But if in the base class (the one that holds the private function) I also have a public or protected function (let's call it plf) to manage the private one (let's call it prf), and in the derived class I create a function with the same name as the private base class function (prf) that calls for the public base class function (plf), I am wondering if there won't be a conflict between both of the same-named (prf) functions?
Assuming the prf function of the derived class is not an overload of the prf function of the base class (because the last one is not visible).
I have to make a maze with arrays, but i cant seem to move down or up or at all. Here is what I have so far
#include <iostream>
#include <string>

I'm working on a project which uses gtk+ and gtkmm. We use them in preference to MFC because the program needs to be cross-platform. For quite a long time, customers on OS-X and Linux have sometimes complained that the program would crash during shutdown but the Windows version (which I work on) never seemed to suffer. However, I'm now transferring my build environment to a new PC and I'm noticing the same shutdown crashes. It's a bit complicated so let me start with a small example:-
Code:
namespace Whatever {
class B {
public:
virtual ~B();
private:
int bb;

Suppose I run the above program. When it stops at breakpoint #1 I make a note of the value of pA. Eventually the program reaches breakpoints #2 and #3. At each point my this pointer is exactly the same number. If the value of pA was 0x03604fb0, my this pointer is identical at both stages.
Now let's consider the real example:-
Code:
namespace Gtk {
class Widget {
public:
virtual ~Widget() {}
[Code] .....
Suppose I run the real example. At breakpoint #1 the value of pW is 0x03604fb0. But by the time I reach breakpoint #2 my this point is slightly different:- 0x03604fcc. It doesn't seem right to me and I'm wondering if it might be contributing to our shutdown crashes.
I know how to define a shape and attach it to a window as follows:
#include <Simple_window.h>
void cir() { Circle c(Point(100,100),50); }
int main() {
Simple_window win(Point(100,100),600,400, "test");
Rectangle r(Point(100,100),Point(300,200));
win.attach(r);
win.wait_for_botton();
}
But how to define a shape (say a circle by that cir() function which is) outside of the main() function? And how to attach it to be visible on window win?

Make a structure for date containing two function one for increment Date() that add to date if day increase month also increase.
2nd for validation for date like day is not greater than 30 or 31.and validate the user input before user entered value.
I have done second. but no idea for first one. Any hint for increment date.

Painting always works on a primary monitor. But when I paint to the secondary monitor, I can only paint directly to its DC. When I use double-buffering technique (with DIRECT_PAINT pre-processor directive commented out) I only get a black screen on a secondary monitor when it should've been red.
First one with direct painting that works:
and then the one that doesn't, with double-buffering technique:
