I am trying to make a simple c++ program that will read some text in the html page. Here is the source of the html i want to read.
<html>
<body>
This is a test message.

I tried to look around and I came across a function called InternetReadFile but I can't find any example similar to what I want.
How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.
Here I want to connect to website every 60 minutes and fetch only first 100 lines of the run.txt file as mentioned above. How can I do this using C++ and asynchronous winsock ???
Code:
#define WIN_OS
#define _DEBUG_PRINT(X) /* X */
//For commn
#include <iostream>
#include <string>
#include <stdlib.h>
#include <assert.h>
[Code] .....
I would like to be able to call c++ library from HTML page. So on HTML page I have area for some possible input (url, name, email, etc) and that info is passed to c++ and calculated info and may email someone; or pull info from text file and display on html page. Realizing PHP or something similar would be easier, I really want to make these calls from HTML pages. ???
View 2 Replies View RelatedI created a MFC dialog using CDHtmlDialog and added a HTML page with many controls and one of them is a IMAGE tag. I got a default image loaded from the hard drive displayed in the HTML page. Up to this part, everything works fine.
Now what i want to do is, dynamically change the image based on the user click on one of the HTML buttons. I don't want this image source to be hard coded in the HTML nor the image source send from the MFC app.
What i want is for the MFC app to send the image data to the HTML in some (binary) format and then the page to display the image.
The possible option i was thinking of was to read the image file which is already in my hard drive as a binary file and send the binary data across to the HTML as a memory buffer, and then use JavaScript to decrypt this binary data and display the image.
Basically what i want is for the HTML page to display a image from the memory. how to do this?
I am writing an MFC app in Visual Studio 2012 that will open a JPG file as binary and read all the contents to a CString.
I am able to read it to a std::Vector, but that doesn't work much as i need to pass all the binary content as a MFC CString to another function.
More Update:
Let me explain the problem a little more deeper.
I am trying to call a JavaScript (JS) function in a HTML page and then want to pass the binary date. The C++ function that calls the JS is given below.
bool CallJavaScript(const CString strFunc,CComVariant* pVarResult);
The 1st argument is the JS Function Name and 2nd is the one to pass the Binary Data. 1st argument works fine as i am able to call the JS fucntion called "LoadImage" without any problem. Problem is with 2nd argument that's supposed to take the Binary data of the JPG file.
If i try to pass a std::Vector or std::string then it will give me an error.
But it's happy if i pass CString. But then with CString there's a problem with NULL characters.
Actually my plan is to pass the binary of a JPG to a JS function and let it display the JPG in the HTML page.
Can i typecast a Vector or std::string to a CComVariant*?
I'm working on a CGI application. I'm trying to test my input with a switch statement and output the result with html tags to populate a web page. From within the switch, I've coded as follows:
HTML Code:
switch(mFunc) {
case 0:
cout << "<p><b>YOU ENTERED THE FOLLOWING TO BE CALCULATED:</b></p>" "<h2>"<< number1 <<"+" << number2 << "</h2>" << endl;
break;
case 1:
cout << "You've entered" << number1 <<"-" << number2 << "to be evaluated" << endl;
break;
I know that I'll need to put this in an html body with a content type as such:
HTML Code:
cout << "Content-type: text/html
";
cout << "<html><body>
";
Am I able to do that directly inside of the switch statement?
I need to know how to parse the html tag using xmlreader.
This is my input. How to parse this input html file
<html> <body> <p><b><i>Hello</b>World</i></p> </body> </html>
convert this file to an excel or ms access file?

Lambton:
Name: chocolate
demand rate: 50
setup cost: 200
unit cost: 5.2
inventory cost: 2
[Code] ....
Program is about a coffee shop with two branches and i have to keep track of the stock in the stores.
Lambton and Callaghan are the stores.
How can i read them ? I know how to open the file to be read..
This what I'm trying to do:
Type two or more lines of text into a file. Write a program to open the file, reading each word into a vector<string> object. Iterate over the vector, displaying it to cout. That done, sort the words using the sort() generic algorithm
But I'm stuck unfortunately.
#include <iostream>
#include<fstream>
#include<vector>
#include<cstdio>
using namespace std;
int main() {
ifstream infile("about.txt");
[Code] .....
Error: 'about' was not declared in this scope
The program runs fine but i just want it to read the inputs from a text file rather than user manually entering it! what changes should i make in the codes..
Code:
#include<iostream.h>
#include<stdio.h>
#include<conio.h>
#include<math.h>
float friction,flow;

This is about reading a "txt file" and storing the contents in a variable. But i've got problems with it because normally, it is space delimited, that is, values separated by spaces are considered different values. How am I going to make C++ read the whole line including spaces?
View 14 Replies View RelatedI would like to program a simple finite element solver in c++ (I'm a relatively new programmer by the way). This is the issue, I have a text file with all the information of the model arranged in matrices; an input file would look something like this:
*nodes
1 0 0 0
2 10 15 0
3 17 2 0
4 -4 -1 0
*elements
1 1 2
2 2 3

2 7.0e4 0.21 2.11e-9
*loads
1 0 0 0

So, i want to read this text file and get each of the "*" matrices in its own array. The size of the matrices is not know.
I am trying to read lines from a .txt file like this:
// "file.txt"
This is the first line.
This is the second line.
To do this, I tried using the following code:
int main() {
std::ifstream data;
data.open("file.txt");
[Code] ....
The output I want is:
This is the first line.
This is the second line.
However, all I am getting is:
This is the first line.
I can't quite see why this isn't working. I am decently familiar with file streams in C++, so I thought I would know what I was doing, but apparently not.
I need to open a text file game_scores.txt and i can not figure out a way to.
#include <iostream>

the code is used to read the text and take the first 4 pieces of info but i do not know how to do it. i have already created the text file and moved it into the source. i am using visual studios 2012. In 2010 the text file would show a relative path, it doesn't in 2012
How can I read just the first column of this from a text file?
ORG 100
LOAD X
ADD Y
STORE Z
HALT
X, DEC 49
Y, DEC -80
Z, HEX 0000
I have
while (! sourceCode.eof() )
{
getline(sourceCode,symbolValue,'
');
sourceCode >> symbolValue >> codeWord >> value;
symbolTable << symbolValue << endl;
}
so the data file is a .txt that is going to be pre-written like this:
numbers:
562
444223.123321 312233.31222 3232323.31122
332231.323223 333232.32323 3232322.32233
am i reading the txt correctly? why are the numbers so weird when i "cout" to check?

Reading in a maze into a 2D array. The first two reads will give me the dimension of the maze(ex. m x n maze). So in order to create the 2D array i need the first two reads. Then after it is created it will read the rest of the data which are 1s and 0s. I have to create a program that will solve the maze but i cant test my movement code if i cant read in the data first. the entire program compiles but to test if i read the file i have a function to print it. But it says "There are: 0 rows and 0 columns " so it didn't read anything since rCount and cCount are initialized to 0. and basically the maze has nothing in it.
Code:
#include <iostream>
#include <fstream>
#include <stack>
#include <cstdlib>
#include "position.h"

I know the size of the data is 2*500.
In matlab I can use like
fid = fopen('example.txt');
data = fscanf(fid,'%f,',1499500);
how should I write in C++?
read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2
139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
while(getline(input, line)) {
istringstream ss(line);
ss >> match_code >> team1;
string temp;
while(ss >> temp) {
[Code] .....
In that missing part, I need to get the second word of team name if there is one; and the three odds that are odd1 odd0 and odd2.
Each line of the text file has first name, last name, and a salary. Something along the lines of this:
john doe 4000
bob miller 9000
I want my program to take the first name, last name, and salary of each line and assign them to strings. I have tried this so far:
while (inFile){
inFile >> firstName;
inFile >> lastName;
inFile >> grossPay;
cout << firstName << " " << lastName << " " << grossPay << endl;
}
When it outputs the names and the salary, the last line of the text file gets output twice by the program.
