Visual C++ :: Convert XML Attributes To Class Using Tinyxml
May 8, 2013
i am trying to create a firework display by reading in the fireworks off a .xml file, which will then iterate through and launch each firework.
I followed a tutorial on dinomage to find out how to use tinyxml, i learnt that i can store the attributes into char pointers but i dont know how to convert them to GLfloats to store them in my class variables.
I did try using atof but when i ran the program i got loads of errors which im guessing is because the pointer only stores the address which im passing to my variable.
Update
i have found out that tinyxml is not compatible with vs2010 but tinyxml 2 is, so i have changed my code but am still having trouble loading my attributes i have added error checking, and it prints out that the xml has loaded but then it wont load the root
I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?
I am using TinyXML 2 for the data of my RPG game, I am almost done with the tilemap parsing system, but I just couldn't figure out how to extract csv data that I have in my XML file, like this:
To the topic: I've been following "SDL game development" book by Shaun Mitchell and (besides the many others in the past) I've encountered a problem in one of the chapters.
I'm in "creating and displaying tile maps". The chapter uses tintxml to load data outside the code, which is used to create a "map screen".
The problem is that the program work perfect except for not loading and/or rendering this "screen".
I know this is too vague of an explanation, but I wouldn't know what else to say.
I'm leaving the link to the repository with all the code: [URL]...
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:
I'm supposed to write a program that is able to save a list of items such as books, CDs, or DVDs. The items that are saved must have attributes associated with them. For example a book has a title, author, publisher, and ISBN.
I'm supposed to create a program that is able to save the database of items to a file on the hard drive and also retrieve it from the hard drive.
The user should be able to
1. Enter items 2. Display a list of the items 3. Save the list to disk 4. Read the list from disk 5. Sort the list 6. Exit the program
I know I should use arrays and structs but I don't where to start.
Does the VAO (glGenVertexArrays/glBindVertexArray/glDeleteVertexArrays) store the enabled/disabled state for the Vertex Attributes (glEnableVertexAttribArray/glDisableVertexAttribArray) or should I re-enable them every time?
Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.
I have to write a c++ program to read html code and do bunch of stuff. One thing that i have to do is to count the no of attributes and sort them in descenting out and print out only first 10 frequently used attributes. I counted them using maps and sorted them using multimaps but now dnt knw how to print only 10 elements
for(std::map<string, int>::iterator it = Element.begin(); it != Element.end(); ++it) Elements.insert(pair<int, string>(it->second, it->first)); for(std::multimap<int, string>::reverse_iterator it = Elements.rbegin(); it != Elements.rend(); ++it) { cout << "Element: " << it->second << " : " << it->first << endl; }
This is how i did it . How to display only 10 elements and not all the elements.
I have encountered a problem with template class. I have made a template class that converts a value into a string, and then made another template class that converts string to T if its possible. Now I need to overload >> and << operators for type T.
template<typename T> string toString (const T &value) // convert a value into a string { ostringstream os; //os << value; return os.str();
I wrote this program to create a list of medical resources and their attributes, a task I have been performing repeatedly lately. I'm still fairly new to C++, so I thought to create a structure "Resource", and then an array of those structures "city[300]". My problem is that the input doesn't seem to be happening: the program runs, but when it prints to screen/writes to the file at the end, all the shows is:
Resource Type: Name: Address: Phone: Website:
for every resource that was input. All the fields are blank.
I am trying to make this code working and to remake it to work also for RGB to HSB? This code is for C and I need to make it working in Visual Studio C++ .
Code: // mask1.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <stdio.h> #include <math.h> typedef struct RGB_t { unsigned char red, green, blue; } RGB; typedef struct HSB_t { float hue, saturation, brightness; } HSB;
[code]....
Error I got is error C3861: 'fmaxf': identifier not found
What file or namespace should I include. Do I need to add some library into linker?
If I drop this regular dll project and create a new MFC extension dll project, it will involve too much work. I wonder if there is relatively easier way to convert an existing regular dll project to a MFC extension dll project? BTW, how can I tell a MFC extension dll project from a regular dll project?
Problem:Given any amount of money expressed in dollars, and cents, this program computes the number of 100 , 50, 20, 10, 5 and 1 dollar bills and number of quarters, dimes, nickels, and pennies to be returned, returning how many of each denomination are included.
I figured out how to program it correctly for the most part except I cannot figure out how to handle large numbers, such as 14.49999999999999999999999999999999.When converting that number to int it returns it as 14.50. How to handle converting doubles, similar to the one above, to an integer correctly?
This is the code that my teacher did not want, since I handled the input as a string:
Code: #include <iostream> #include <string> #include<iomanip> #include<windows.h> using namespace std; int main(){ const int hundredsConst=10000, fiftiesConst=5000, twentiesConst=2000, tensConst=1000;
I'm trying to read in two instances of date and time (from user input) into a string value (MM/DD/YY hh:mm). I need to be able to calculate the difference between the two in order to return how much time has elapsed from the first date/time to the second date/time.
What would be the most efficient way to go about obtaining said results?
I was thinking I need to convert each year, month, day, hour, and minutes into its own integer variable, after researching immensely online I'm still not sure how to convert from a string of characters to an integer.
I am in need to convert some C# code into C++ equivalences. But I don't want to spend the efforts to do so. Is there an handy way to convert an existing code of C# into C++ (unmanaged code)?
I am a novice programmer(still...) , and I am trying to build the Code Project project located at this address:
[URL] .....
The project page is titled " Remote Control PCs ".
I would like to use this program plus I wanted to practice programming using the code base. However, I don't have MFC so I thought I would just convert it to non-MFC.
For example, It seems to me that any class inherited from MFC would need to be reimplemented. I think I also need to reimplement any code that uses "stdafx.h"
I built a custom project out of the zlib library and compiled it as a Windows library with the /MT settings. Both 32 and 64 bit library files, in Release and Debug mode, are included. The ZLIB.H and ZCONF.H files are also included. For examples of single-threaded usage, see the CZLib class. For examples of multi-threaded usage, see the classes CDriveMultiThreadedCompression, CMultiThreadedCompression, and CZLib.
1)How should I go about compiling this zlib custom project?

I receive a byte stream. The first 8 bytes contain an Identification number. I receive at first the lowest byte and at the end the highest byte of the number. How can I transform this into a double value and later back into the bytestream? In the past I hard only 2 Byte values and there I could use things like MAKEWORD and HIBYTE and LOWBYTE to convert the values
