i have this program that i am undertaking.....this project needs to store customer details, edit them and delete them...now i am facing the problem of deriving a code to edit those details...

You are requested to create an inventory control application for a drink stall (give a name to the stall). The application is used to show the list of drinks the stall sells, how many of each item on‐hand and the cost of each item. The records are to be saved and retrieved to/from a binary file called “drinks.txt”. For each drink in the stall, your program is to keep the information as a Record Structure called DrinkRecord. The structure should at least consist of the following:
(1) Item Number
(2) Item Name
(3) Quantity
(4) Unit Price
Your application should have the following features:
(a) Display a drink information
(b) Add a new drink information
(c) Update a new drink information
(d) Delete a drink information
(e) Display all drink information
#include <string>
#include <fstream>
#include <vector>
#include <iterator>
#include <algorithm>
#include <stdlib.h>
#include <iomanip>
[code].....
Everything works fine with minor issues, but I'm having trouble with the editing function. I need to be able to search for a specific drink then be able to edit its contents and print the new contents to the file. I have not created a structure yet. I will do that as soon as possible.
Basically I am to create a program that will read two saved text files; one is [2x4] ~ (matrixA.txt) and another is [4x2] ~ (matrixB.txt). The program is supposed to read both text files, multiply them, and generate an output that will be saved as ~ (matrixC.txt).
So here is my horrible attempt at it:
Code:
#include <stdio.h>
int main() {
FILE * fileA;
FILE * fileB;
FILE * fileC;
[Code] .....
And these are the compile errors...

I have got 4 radio buttons on my form and & i am trying to match the text for these radiobuttons with a record in one of the database tables. Essentially I would like when the submit button is clicked to match if the selected or clicked radiobutton Text with a database record. And if this matches a messagebox to be displayed saying "match" and if not matched the messagebox should show "no match found"
What I have done so far:
private void button1_Click(object sender, EventArgs e)
{
bool correct;
String Option1 = "";
[Code]....
in this case the "Emp_1" is the matching record , when I run my project when other options or radio buttons are clicked it executes the messageBox showing that it matches even if its not a matching record. What I am trying to say is that it does not execute the else {MessageBox.Show("no match found");} when records don't match.
I'm having a problem in my Library assignment, this section of my code is for reading in books saved in a 'book.dat' file on my desktop and inserting them into the linked list. It kind of works, but say if there is two books in the file, it only saves the second book twice.
eg in book.dat:
123 book1 Tolkien 2009 0
111 book2 Rowling 2009 0
So once these are read in, and I call my method displayAll(), it would display the second book twice..
void importFromFile(FILE *fp) {
struct book *aBook;
struct node *aNode;
aBook = (struct book *)malloc(sizeof(struct book));

Well,i hav a question requiring me to edit sales achieved by an employee for a particular month.
I'm having a dat.file which following format
Employee ID
Name
Sales(for a year)
For example
A00001
Harlem Shake
10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 90.00 100.00 110.00 120.00
Wad I wanna is TO EDIT only the sales for July which is 70.00 to a new amount with other months remain intact.
I need to search particular id which will then link to their respective sales.
ofstream outFile;
string empID;
cout<<"Please Enter Employee ID:
[Code] ....
I tried to run myself before.But I could only create a new line instead of replacing.
To my understanding with ios::app ..will use the same file for editing..
Basically what I am looking for is a way to get a block memory, copy it into ram in a format along the line of bit[#], replace the original with a new code that may or may not be the same size(they will be something to ensure does not try to save a fraction of a byte).
Is there an easy way to do this or do I just need to read work from a bin file?
I have a button that opens a file dialog box so that a user can pick a file. I only need it for the path and file name to be passed to another program. I do not want to open the file or care about its contents. I just want the name and path.
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog dialog = new OpenFileDialog();
[Code].....
The problem is that as long as the program is running the file that the user picked is locked for editing. Adding the Dispose() had no affect. Multiselect and ReadOnlyChecked have no affect. Only closing the application frees the file.
I have a .dll file that is used by some kind of launcher. Now the .dll file has some kind of timer on it and after that set of time it wont let me use it, how i can edit that out of a .dll?

I have to ask the user if they want to delete any records. The user can enter -1 to finish deleting records. I have to write the remaining records in an output file. So, i have this, but
1) it doesn't let me enter more than 1 id, and
2) it doesn't output anything to my output.txt.

My size of binary file is 1920 KB and my struct size is 124 kb. now to find number of records in file I divided 1920/124 and it gives me 15.4.... do I add 1 to 15.4 and make it 16 or do i take it as 15?

How to print alternate records from a file using fseek?
I'm trying to write a C program that will take a file that is delimited by colons and separate it out in to 5 sections:
0002:0003:0002:0080:<HTML>
0002:0004:0002:0080:<BODY>
I have the struct code in place but not sure how to actually store each of the 5 parts in memory. Here is the code below:
Code:
#include <stdio.h>
#include <stdlib.h>
#pragma warning(disable:4996)
struct contents
{
int source,destination,type,port;
char data[50];
};

The program will prompt the user to enter a every student's first and last name, major ( of 4 choices CMPS MATH PHYSICS or EECE ), and grade. it's agreed that the professor will enter the name NoMore to stop the entry.
the program willl then store the info in a txt file. after closing the input file, the program will open it again read the records one at a time until end of file, and do some statistics including: highest grade, average grade, and highest average by major.
Finally the program will print the results....
I have faced a strange problem in File Save Routine. I have written a module to save data to binary file . I have designed a structure and put information in that and save it to file . I save multiple such records one after other. I use fwrite , fflush instructions.
The module is working fine. I have saved near about 35 such files. But in one file , the module has saved Blank Records. The file size if perfect but the file is totally blank. It has happened for only one file but need to know the reason.
I can't seem to get my program to read a file that's saved on my computer. Here's my code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ifstream inputfile;
string name;

#include <iostream>
using namespace std;

public:
static const int num = 100;
char publisher[num], title[num], location[num];

Is C# or any other programming language out there that can run like a program that has been installed on you PC? For example say i want my program to run Media player with a saved play list, run spotify, or run a search on the internet?
View 4 Replies View RelatedI'm working with a cross-platform library which defines a function to obtain function addresses from a shared object (i.e. a DLL on Windows). Here's my modified version of the function which works (albeit only on Windows of course):-
Code:
typedef void (*SuilVoidFunc)(void);
/** dlsym wrapper to return a function pointer */
static inline SuilVoidFunc
suil_dlfunc(void* handle, const char* symbol) {
return (SuilVoidFunc)GetProcAddress((HMODULE)handle, symbol);
}
Now, here's the original (cross-platform) version which is giving me a run time error on Windows:-
Code:
typedef void (*SuilVoidFunc)(void);
#define dlsym GetProcAddress
/** dlsym wrapper to return a function pointer */
static inline SuilVoidFunc
suil_dlfunc(void* handle, const char* symbol) {
typedef SuilVoidFunc (*VoidFuncGetter)(void*, const char*);
VoidFuncGetter dlfunc = (VoidFuncGetter)dlsym;
return dlfunc(handle, symbol);
}
That original version fails at the final return line. The error message says "The value of ESP was not properly saved across a function call".
I'm assuming there's a problem with the declaration of VoidFuncGetter (i.e. it'll assume that the caling convention for GetProcAddress() is cdecl when in fact, it's stdcall). What's the most elegant way to fix this and still keep cross-platform compatibility?
