C++ :: Input With String Statement - Output Result With HTML Tags To Populate Web Page
May 3, 2013
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 have an HTML5 form with a number of text boxes on it. I would like these textboxes populating with data retreived from an SQL database, using inline C#. I have a stored procedure that returns the data.

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. ???

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 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*?

how to use the result of an if statement in my program. I'm writing a program for a knockout tournament, so i want to extract the winner of each match to carry forward in the code for use in the next round. I've tried assigning another variable (#define r1w1) and saying that the variable = cName[0] or cName[1] in the if statements like this: (i did this because i thought i could then use r1w1 later in the code)
if(scorea1 > scoreb1) {
printf("
");
printf("WINNER OF ROUND 1 MATCH 1 IS %s
", cName[0]);
cName[0] = r1w1

write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";

I have a window in WPF which I want the user to use to enter the information for a COM Port.
The intent is to populate two ComboBoxs from a two different ObservableCollection<string> which I am having no luck with.
I don't think that it is a DataContext issue, as I am able to get something from the ComRateList when the window opens, but nothing from BaudRateList. Either way I have included the way that the window is opened and DataContexts assigned...
When the code runs, the COM Port list is updated when the window opens - However, it is not updated when the user reclicks the ComboBox which was my intended behavour.
All the adds for the BaudRateList do not populate the ComboBox for the baud rates on start up, nor when the code is running.
When I step through the code, I can see all of the BaudRateList items being added... The window is called by the main window's datasource like so...
OpenSerialCommunication OpenView = new OpenSerialCommunication();
OpenView.Show();
This opens fine.
The OpenSerialCommunication.xaml is as follows: (Note that any business names have been replaced with [snip])
<Window x:Class="[snip].SerialCommunication.OpenSerialCommunication"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

I have this simple code here:
Code:
#include <iostream>
int multiply (double x, double y) {
double result = x*y;
return (result);
[Code] ....
I get the answer 5.94 (which is what I'm looking for). I can't work out why the first example is not outputting a decimal number. I have set the variables as a double so I just can't see why this is not working for me.

I have a question related to switch statement, which the switch in class employee2 gives me error at output. Program compiled well. I am using Code::Block Compiler V10.5. I have created object of class employee2 in main() function to get data from user, store it and display it. At the output, Compiler doesn't show actual output what i am expecting. The fun thing is my compiler printed emocion like (), where (hourly/monthly/weekly) was supposed to print.
Code:
#include <iostream>
using namespace std;
enum period {hourly,weekly,monthly};
class employee2 {
private :
char ch;
period x;
double compensation;

I wanted to take the averages of the whole week and output a print statement. I've tired few ways this like assigning "temp" a pointer, or in each if statement assigning temp to a new variable like a, b , c etc. Then adding them all up at the end and dividing by 7. My issue is I am unclear how to store the number typed for each if statement while the program is running, then have it compute the simple equation. The code in question is below:
Code:
#include <stdio.h>
int main(int argc, const char * argv[]) {
int i, j = 0, temp = 0;
for (i=1; i<=7; i++) {
j++;

c++.....in my program i have 3 string-s (string houses,string ink,string buildings)and i must add function substr()... In the program i need to add a function that receives a parameter of type string. The task function is that the resulting string is inserted characters '=' to split a string of characters into subsets 5 letters long. If you come to the end and no more letters after the equal sign is not added. The function should not display anything but the resulting string is returned as a result. Example:
A function recive: "housesinkbuildings" .The function returns: "house=sinkb=uildi=ngs" in The main program Add call of this function so that it is specified as a parameter string consists houses,ik, buildings.
