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?
According to my project instructions, I have to make a "validation on the delete button, that before a record can be deleted it will check to see if the count of "In-Progress" orders for that product is 0. If it is greater than zero, it should not allow this record to be deleted."
The professor said I have to: "As for getting the count, check your notes and book, specifically looking at SQL and the Aggregate functions. There is a function we talked about in class called "Count(OrderID)" and set the where clause to check for the productID.
I am using the following code that I copied from a website to send some numbers using TTcpServer in C++.
void __fastcall TForm2::Button1Click(TObject *Sender) { //Creating a stream std::auto_ptr<TMemoryStream> myStream(new TMemoryStream); for (byte i = 0; i < 9; i++) { myStream->WriteBuffer(&i,1);
[code]....
I do not understand what is being sent in the byte variable, nor why a byte variable was used. I want to send some strings instead of numbers, but I don't understand what's taking place so I can't identify what to change.
I made client server program with fork ,without using signal handler because I want to see the status zombie for parent server, but when i execute "ps" command i didn't see anything for server or client pid or ppid ,i wonder about how to show the server and client process coz when i execute commad "ps" i saw only ps and bash processes???
Been trying to configure the GridView to display ony 4 rows of data at a time. I thought it wasn't working because I forgot to set AllowPaging to True, but after I did that, I just get the error of
The data source does not support server-side data paging.
Source Error: Line 66: titlesGridView.DataBind(); // displays query results
Here is my Books.aspx.cs code:
// Fig. 29.11: Books.aspx.cs // Code-behind file for the password-protected Books page. using System; using System.Data.Entity; using System.Linq; namespace Bug2Bug.ProtectedContent { public partial class Books : System.Web.UI.Page {
[Code] ....
Am I missing anything or doing something wrong thats not causing it to page & only display 4 titles at a time?
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.
On a right angled triangle, if the user inputs only ONE side length (not the hypotenuse) and only ONE angle, what code is required to work out the hypotenuse? I know how to work out the final side and the remaining angle once I have this.
A sequence point in a C program is defined as "Any point in a program's execution at which it is gauranteed that all side effects of previous evaluations will have been performed and no side effects from subsequent evaluations have yet been performed."
How do you add a value to the beginning of a string instead of the end?
This is for an assignment and I have to convert the user input (always assuming its a valid decimal number) to binary and store it in a string. I've got up to dividing by two to get the remainder ...
I am working on a 2D side scroller game. Where a ball is moving continuously towards right . I used a camera to follow the ball as soon as ball reaches the center of screen. I created a horizontal line to look like the surface on which the ball is rolling.
line runs from x=0 to x=800 (i.e screen width)
NOTE: (0,0) coordinate is at top left corner of display.
Problem: My display is 800 x 400 . Camera follows the ball, but soon the ball crosses x=800 and starts moving in black background. I want that line surface to stay there instead of going out of bound.
Additionally! I generated obstacles from x=800 which also move out of bound along with my line.
What should be done here? This is just my first c++ game project, so i might be skipping things that can solve the issue.
[Update] these screenshots manage to show, what the real problem is: [URL]
I want to calculate the total some of delay pf receiving Side Packet . Code is as Follow ..
What is weird that even if i invoke a sleep of 2 sec ,than its show delay always zero. Delay will be in microsec ..Is there any problem with logic or anything else..
Code:
do {#pragma omp parallel private(nthreads, tid) { /* Obtain thread number */ tid = omp_get_thread_num(); if (tid == 0) { nthreads = omp_get_num_threads();
Right after I close FIFO on the producer side, the app on the consumer side gets into an endless loop. select() returns that FIFO is ready to read. Below is the excerpt from the consumer code. The FIFO is opened "blocking" on both ends.
I have a question concerning the CDialogBar (:CControlBar).
I have a MDI application with a dockable toolbox (CDialogBar).
The user is able/allowed to move the DialogBar and to dock it at the right or left side When I dock at the left side, the content of my mdi-application (so all other open windows) are moved right (so the dockable bar moves the windows).
If i dock at the right side, nothing changes.
How can I change the behaviour of the bar, that the windows inside the application keep the same position when I dock left ?
(Problem is, that my windows are aligned on the right side of the application). When I dock the bar on the left, the windows are getting moved in the not visible area.)
I am trying to test my client-server socket program wherein the client connects to the server,client sends a message, server receives it and echo back to the client.So far, in the program server receives the message from the client, prints it BUT when it tries to send the message back to the client it shows an error.
sendto(): Invalid argument.I am new to socket programming.
Code:
//Server #include<stdio.h> //printf #include<string.h> //memset #include<stdlib.h> //exit(0) #include<netinet/in.h> #include<sys/socket.h> #define BUFLEN 512 //Max length of buffer #define PORT 10003 //The port on which to listen for incoming data }
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
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): }
I am trying to send a packet across a client/server communication. I am getting a seg fault (while running the program(It compiles fine)) when I try to read the neighbor file, You should be able to see this below the comment /***** Read neighbor file***/ :
Where are the c programming variable name rules defined? I usually use these two websites for figuring out these kind of things but I don't see it anywhere.
I am trying to read all the 9 letter words in a words list text file and print them to the screen. Here is the code I have so far, but I am currently printing nothing.
Code:
#include <stdlib.h> #include <stdio.h> #include <string.h> int main() {
I'm trying to make an alphabet soup on C programming, and I'm stuck with a problem.I need to make a function able to automatically find all the words that exist in alphabet soup.
I have attached a circuit diagram below, which has been tested. Currently you have to manually push the switch to change the brightness of the bulbs. I want to program a chip to automate this.
Over 90 days the chip will output a high signal in replace of the switch every set period of time (say once every 1.5days). I can use any chip but the smaller the better!
I would like to make a program for final project, which can let me send any file to my computer at home, and i can access any files in my computer when i am not at home.sending and getting file will be with socket programming.
i would like to reach all folders in computer, not only the folder, where client program exist. how can i access other folders at remote computer by using my program?
why an array would lose its contents when I believe it shouldn't. Below is a skeleton program just to kind of show what seems to be happening. Basically I set up the delims array with just a star. The program runs a good number of times but at some point the delims array gets lost. My guess is the stack is overflowing or something? But it "appears" all other variables are ok (although I cant be sure).
I move the char delims into the while loop. What is this "actually" doing to the original delims variable ... are we wasting memory here (bearing in mind the original delims variable is sometimes loosing the string :/)
Write a program that orders three double numbers by increasing value. The program should include a function named sort3 that takes three double * arguments (pointer to double). The function prototype is void sort3(double *x, double *y, double *z); The function should reorder the values pointed to by its arguments so that after the call sort3(&x, &y, &z); the numbers satisfy . Your program should input data and print results using the following format:
Enter three numbers: 4.7 1.4 3.2 The ordered sequence is: 1.4 3.2 4.7
And here is my program: C code - 32 lines - codepad
I am getting a lot of errors when I run it through GCC. I can only use pointers.
