Visual C++ :: Make Transition From Console Programming To GUI Programming?

Nov 30, 2013

my a book or website where I can make a transition from console programming to GUI programming. I'm totally confused about this. I know how to program in console and can make a whole program based on console. I also know the OPP programming, but it's clear that nobody uses console programming anymore.

C++ :: Use Fgets And Strlen To Calculate Length Of Textstring

Oct 31, 2014

#include<stdlib.h>
#include<stdio.h>
#include <string.h>
int main() {
char input[256];
char buffer[256];

[Code] ....

The output of this short program is really weird. When I type 123 from the keyboard,I get the following answer in console window"123 length=4".Why the output of length is always 1 more than the actual length of the string that I type in.

C :: Convert Float To String In Order To Use Strlen Function

Apr 4, 2013

Any really simple way of converting the following float to a string so I can take strlen()?

I have looked up solutions but they are either too long or they confuse me.

C :: Create File To Write Text And Read Back The File Content

Mar 15, 2013

The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.

How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?

If "Y" Than Inputs Are Taken From Next Line Else Input Ends.

But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.

Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

C :: Convert List Of Names From One Text File To Email Format In New File

Jan 19, 2014

I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.

Code:

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];

C :: Writing A Simple File / Text Parser To Read A Config File

Feb 6, 2014

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:

Code:

readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}

[code]....

Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.

My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.

C :: Parallel Port Programming - On / Off LED

Sep 9, 2014

I try to ON and OFF the LED's via parallel port. I connect the cathode of LED's with pin number 18 that is ground and anode of each LED is connected through a 1K resistor to pin 2 to 8. I write the following programe

Code:
#include <dos.h>
#include <stdio.h>
#include <conio.h>
#define PORTID 0x378
void main(){
outportb(PORTID,0x00);
getch()
}

But when i connect the LEDS to the parallel port all the LEDS are LIT while i also change the 0x00 to 0xff and so on. But no effect on the LED's.

C :: How To Check Dates In Programming

Mar 6, 2015

I'm supposed to make a program that can tell which date, out of any number of dates entered by the user, is the earliest date. However, this is based off another program that I did not do in the last chapter. Since it's a pretty simple program to use as the base for the more "generalized" one, I decided to make the more basic one that can only take two dates, first. If it was just one integer, I could just use date1 for the first date and date2 for the second date, but each date uses 6-8 separate numbers.

how do I tell it something like, "if(date1 < date2)", with date1 and date2 including their month, day, and year. I could do a separate integer name/tag (I forgot what they're called) for each number, but that sounds like doing a lot more adding and subtracting, and like it could easily get messy.Should I, or can I, add all the numbers under the "date" together to see which date has the "lowest number" or "earliest date", or should I somehow handle each number, that is month, day, and year, separately?Here's the code so far:

Code:

include <stdio.h>int main(void)
{
int date1, date2;
printf("Enter first date (mm/dd/yy):
");
scanf("%d/%d/%d", &date1);
printf("Enter second date (mm/dd/yy):
}

C++ :: Can Be Used For Server Side Programming

Nov 28, 2013

I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.

Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.

Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?

C++ :: Read From A Txt File And Then Write A New Text File With Sorted Line

Jun 11, 2014

I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?

I want to sort the lines based on the FIRST value.

Example text file contents:

values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324

Output: Text file containing

2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43

It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?
