i have written a student information storing program. it has add,delete,list,and update menu (in program i have written update == uptade,i know : P )
my question is i cant delete or update the information. where is my failure ?

In my project i need to update the attn_dateTimeOut in database.After i updated it will automatic delete the specific row record that had been updated. I had two question:
1) in my database there are a few table is assign not null."attn_dateTimeOut" is a table that haven insert any record. When i update it using below code,it work and can update but it comes out error.Error show "record cannot be null".
2) I want t make it when i updated the "attn_dateTimeOut",it will auto delete the row of updated record.I do usign back code "DeleteRecord" but it nothing change!How should i do?
Here my code:
private void txt_proximity_KeyPress(object sender, KeyPressEventArgs e) {

if (!String.IsNullOrEmpty(txt_proximity.Text)) {

I want to write a C# application that uses the Compact Edition of SQL Server and I want to update the data file on a weekly basis with the current statistics. How should I proceed. It will be a stand alone application. Do I update the data file with a script or something else?
View 2 Replies View RelatedThe file name is "movie.dat" and currently i was able to save data into the file in this order:
[movie_code] [movie_dur] [movie_title] [movie_rating] [movie_dir] [movie_genre] [movie_status]
[12345] [120] [Movie] [PG13] [Director] [Comedy] [Active]
I want to search for the "movie_code" and change the [movie_status] from Active to Inactive.
So lets say for example i have a movie code 12345 saved in my movie file. I want to change the value from "Active" to "Inactive"for argument sake.
This is the code i was trying to do it with:
Code:
FILE *movie_fp;
movie_fp = fopen("movie.dat", "r+b");
int m_code;
MOVIE movie_data;
printf("*** Welcome to the movie updater! ***

I need my Unix program to generate a directory with a format like this: "hinesro.<pid>". I have some code that mostly works, except for the directory ends up with a question mark on the end, like this: "hinesro.12345?". I need it to just display the directory without this question mark. Here is my code:
Code:
// Using headers sys/types.h, sys/stat.h, unistd.h, and stdio.h
int pid = getpid();
char prefix[] = "hinesro.";
char fileName[0];
sprintf(fileName, "%s%d
", prefix, pid);

Student StdStruct;
fseek(file, -sizeof(StdStruct) , SEEK_END);
fread(&StdStruct, sizeof(StdStruct), 1, file);
[Code] ....
The problem is that ... Even though it is reading from a a file, it is not reading a one struct. In this piece of code I'm trying to read the last struct, which should be k... The struct itself is here
Code:
typedef struct {
char StudentName[30];
uint16 StdAge;
uint16 StdNumb;
}Student;
And here is my input and output:
INPUT:

1 g 1 2
1 h 3 4

1 k 7 8
I need to read some infos out of a .txt-file.
The problem is that i dont know how to do because 'getline' won't work i think.
the file looks like this:
*******************
Inventory of MyInventory
*******************
Some info
More info
-------------------
000 Toys 6.25
a short description
126/44 Cards 2.25
some text
*******************
Inventory of MyInventory2
*******************
Some info
More info
-------------------
000 Toys 6.25
a short description
126/44 Cards 2.25
some text
So what I need to know:
- the name of the Inventory (MyInventory, MyInventory2...)
- the numbers in each row (000,126/44...)
- the name what it is (Toys,Cards...)
- the price (6.25,2.25...)
- and the description(problem here is, that there are not the same amount of words for each description)
I tried it with 'getline' but this is not working because the lines are so different each time.
I want to receive an information from a file. For instance, you created a file name "sample.txt" via fstream and stored a bunch of people's name, address, phone number in that "sample.txt".
Now, I want to see what's stored in this file. Suppose, I wanted some particular guys address, phone number by just typing is his/her name.
How to relate the name with address and phone number of particular people? I just started the file creating so I wanted to know about it.
#include<iostream>
#include<conio.h>
#include<fstream>
#include<string>
using namespace std;

I have a compressor that takes a file and first compresses it to an intermediate file "temp.lz", before compressing it to the final format. Immediately after that the file be removed by calling c's remove(char*). The problem I am afraid of is if calling this compressor from different processes is safe because of the intermediate file created which has the same name for all. (say temp.lz). Will I have problems when callinga sytem call from different process something like: system ("compress -i test.txt -o test.z") ?
I was thinking of rewriting the compressor to avoid the use of the temporary file but that is a bit awkward. I just need to use a temporary stream (file) different for each process to avoid race conditions.
I'm trying to add more student information to the specific txt file. I did struct my student information and separated it with an array with max size of 200.
The inside of my current file looks like
Toshi
Aka
Nonal
Donald
The first one represent student[0] and next one is student[1] and so on till student[199]. Right now, only 4 space is occupied, which means the array has information till student[3] but not from student[4] (I guess it has null condition).
What I want to do is, I want to add a new student information to student[4] and till student[199] once at each time.
So, my prompt will look like
Would like to add a new student? Y/N
(if yes goes to below statement and exit if NO)
Hi. Please enter the information of new student. ___________
Student added. Please press any key to continue.
If the key is pressed, it goes back to my initial prompt and continues till I press N.
I sure I'm not using for loop to do this thing, because I'm adding student name one by one.
However, the array is already occupied by other student name till student[3] so, I want to add a new student information to student[4] (I don't want to overwrite the current information). And if student[4] is occupied, then [5] and so on.
I want to take the informaition from this file and save it into a struct the file conteins name age year (in char) and a grade it is somthing like this

I am trying to parse a text file that contains information and i cant seem to get started. For example, the text file looks like this:
idx=929392, pl= 12, name= someperson
age=19
state=ma
status=n/a
idx=929393, pl= 12, name= someperson2
age=20
state=ma
status=n/a
idx=929394, pl= 12, name= someperson3
age=21
state=ma
status=n/a
I want to parse the name and age into another text file like this format:
someperson 19
someperson 20
someperson 21
possibly include other attributes next to the age like idx?
Create a simple data file like the example shown below containing the 4 dates below plus 10 or more additional dates. The file should include 1 date per line and each date should have the form MonthNumber-DayOfTheMonth-Last2DigitsOfTheYear with no extra spaces. All dates should be in this century. No error checking for invalid dates is necessary.
My Output displays like
February -19,1991
How do I get my program to ignore the dash between the dates?

I created a simple program that writes some text to two different text files. how to create a program that would retrieve the information from those two files, and put them in a single file, first the content of input1 and then the content of input2. how to do this. Here is the program that I created that creates the two files.

#include <fstream>
#include <string>
int main() {
using namespace std;
string input1;
ofstream fout("input1.txt");

Perhaps my original wording on this was confusing so I will ask a different way.
if I have a text file called
data.txt
and it has the following in it.
12345
67890
12345
67890
how would i read this information into an array called
int data[4][5]
This is in C.
this last few days I've been coding this one particular file
Hero.cpp
namespace Hero {
namespace {
// all data here
}
}
then the code grew a bit to about 700 line
Then now I want to implement hero skill system It needs the access to data inside the unnamed namespace where I put just about everything.. but it's unnamed namespace, it's only valid within one file and I should hide all that data from Hero interface in Hero.h How should I do this ?
I have a network data file that looks like this:
2476

213
321
426
531
634

945

The first row has two values - number of nodes (24) and number of links (76). Then it has all the link details (76 rows of data). I want to read this data. I have written out the following function:
First the structure definitions:
typedef struct {
int arcno;
int tail;
int head;
} arc_data;
typedef struct {
int forwardStarPoint;
int reverseStarPoint;
[Code] .....
The code is able to read the first line of data (i.e. it displays the numNodes and numArcs as 24 and 76). But then I get a lot of errors like this one
`Access violation writing location 0xCCCCCCD8`.
The program then crashes.
For my intro to c programming class, our homework requires us to read a data file and emit various bits of information. the data file looks like this
#Domain: the URL
#Alexa: some kind ranking, small numbers are better
#Rank: another sort of ranking, big numbers are better
#Domain Alexa Rank Site Name
#------------ ----- ------- ---------
amazon.com 13 1177136 Amazon.com
google.com 1 4533883 Google
youtube.com 3 3637788 YouTube
[Code] ....
I've started and am able to get the correct number of lines, and the alexa number, but I keep getting some errors and am just unsure where to correct my code. This is what it looks like;
Code:
// Lexi Anderson
//CS 156
#include <stdio.h>
int main() {

and once compiled, I get errors.
I was trying to make a program in C that could take Personality Information from the user and store it in a text file. Then, when asked, could compare the results to other entries in the so called "data-base" and tell which is the best match. I tried a whole lot but couldn't think of a proper way.
(Stings and File IO are not my strong points)
I am using Code Blocks 10.05 and the standard GCC compiler.
So I have to read from a file, and store the information in separate variables. My problem is that for some of the information I need multiple words, and for others I don't, so I cant simply store 1 word into a variable and store the next in another in so on. To demonstrate what I mean let me give an example.
Dog Cat Blue Bird Snake White Horse
I am able to store "Dog","Cat","Blue","Bird"...etc in variables but I don't know how to make it so I can store "Dog" in one variable, "Cat" in a second variable. and "Blue Bird" in a third variable. "Snake" would be the 4th and "White Horse" would be the fifth. How can I read a file and manipulate the pointer to grab what I need?
