C# :: Change File Format
Jun 20, 2013
I have installed VS 2010 and VS 2012. VS 2012 uses SqlServer CE 3.5 and VS 2012 uses SqlServer CE 4.0.The problem is that when a project uses a 3.5 file it tries to open it with 4.0 even if the app.config says to use the 3.5 provider. The version of the assembly is pulled right out of the GAC. I uninstalled 4.0 and the reference auto updated its version to 3.5.1. However after installing 4.0 again it changes to 4.0. The error I am getting is that 4.0 cannot open a 3.5 file....they changed the file format from 3.5 to 4.0 and they are not compatible.

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];

The requirement is to capture statistics of uuid occurrences for ALIVE/SEARCH/BYEBYE (it can be all 3, combinations of 2 each, or one alone) in a dynamically populated file in run time.
I am able to print all 3 combinations, but not in combination of 1 or 2 e.g.
If my input.txt is like this :
uuid:22314754-a597-490b-8a93-02cfae01036b ALIVE 16
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:50e65653-7525-485d-83bf-d293558c4264 SEARCH 132
[Code]...
Code:
#include<stdio.h>
#include<string.h>
struct uid
{
char uid_val[100];
char state[100];
int temp_count;
int alive_count;
int search_count;
[Code]...
Gives the following output ->output.txt)
Device ID ALIVE BYEBYE SEARCH
uuid:22314754-a597-490b-8a93-02cfae01036b 16 8 8
uuid:50e65653-7525-485d-83bf-d293558c4264 32 8 132
uuid:55076f6e-6b79-4d65-6497-180373763bc1 113 112 111
uuid:T0100203354 1 2 3
I want to generalize the code such that uuid occurrence does not have to be all 3 (ALIVE/SEARCH/BYEBYE), the occurrences can be any combination and code should work. e.g my code gives wrong results when input.txt contains the following:
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:55076f6e-6b79-4d65-6497-180373763bc1 ALIVE 113
uuid:55076f6e-6b79-4d65-6497-180373763bc1 BYEBYE 112
uuid:55076f6e-6b79-4d65-6497-180373763bc1 SEARCH 111
uuid:T0100203354 BYEBYE 2

I have a multivalued function (created in some other software Mathematica) that looks like f[8.7,5.4]=4.8+8.7*I. In other words it's a complex valued function of two variables. I store the output of this function over a range of parameters in a text file that looks like:
Code:
f[1,2]=9.8+8.7I;
f[4,5]=5.6-5.21I;
.
.
I could store it differently if that is easier, but essentially I just want some c++ code to read this in and store it, either in a vector type structure or Dictionary? (I don't think a double array will work as I don't know how long list of data is in advance).

My objective is to create a file and save some text in it. But the twist is that file should be created in pdf format.
I have written following code:
Code:
#include<stdio.h>
Code:
int main() { FILE *fp;
char ch;
fp=fopen("file.pdf","w");
fprintf(fp, "%PDF-1.3"); //to initiate data storage in pdf file
printf(" Enter data to be stored in to the file:");
while((ch=getchar())!=EOF)
putc(ch,fp);
fclose(fp);
return 0;}
Now my file is created in pdf format, but when I open it by double click on it, it is not open and gives the message like: "Error in opening document. This file is damaged and could not be repaired."

I'm having trouble reading my data from a .txt file into a structure of the format shown in my code. I've made my student database in the program below based on user input and I didn't have a problem with that, but now it's come to input from a file it's making it difficult.
My three tasks are:
(1) A table containing 1 row per student, containing the student ID number and all of the student's marks.
(2) Another table, containing 1 row per student, containing the student ID number and the average mark obtained by that student.
(3) The average mark for each subject.
The assumptions to be made are: The student ID can begin with a zero, and should therefore be read in as a string.The test data will contain 20 students but the program should be able to deal with up to 100 students.Assume there are no more than 4 different subjects.
So based on the first assumption I've arranged the data in the file in an order in which the student ID begins with a zero:
003953 Computing 38
003953 English 88
003953 Mathematics 29
003953 Physics 83
073241 Computing 63
073241 English 99
073241 Mathematics 32
073241 Physics 73
...for twenty students, 80 lines of data. Now, on the assumption they must be read in as strings, this is what's making it tricky to store in the structure because, I've got 80 ID numbers but 20 repeat themselves 4 times. Once I've got this data in the structure below the tasks I won't have a problem with because I can just base it on a user input program but the data's already stored instead.
Below is my code for user input associated with task (1). In this example the IDs are stored as ints but for the file they will be strings. It compiles fine, displays the data as shown in the assignment sheet, but I don't know how to get the data into my structure. I can store the data in a structure of three arrays using fscanf() no problem, but it's not very "workable" for what I need to do with it.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>

My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;
double cents;

For particular assignment, I am asked to evaluate data from an inputfile, let it be named "infile.dat". Next, it is required to output to this same file, but with the name of this file altered to reflect the changes of data. For example, if I want to change the original file name to "changed_infile.dat.altered" by adding the "changed_" prefix and ".altered" suffix, how could this be done?
From my understanding, there are no functions in <fstream> that could change the file name. However, there is a rename function in <stdio>, but it's not exactly what I am looking for because I want to append a prefix and suffix to this existing inputfile name. Although I could apply a brute force method by simply doing rename("infile.dat", "changed_infile.dat.altered"), I want to have my program to work with various input files of different names.

I have an application which is used for calibration for electrical components. Here I want to set a rootpath for this application. I did some research and I found out that I can get the rootpath of the application (that is where the exe is stored) But what I am really looking for is once I start the application the root path should be what I assign. For instance currently the root path is "C:UsersPublicDocumentsABC.ToolsProjects" but I would like the root path to be "E:New ABC" Is this possible? I wrote some code where I call the exe of the application and it opens the file in a folder that I specify :
private void NewJournal_Click(object sender, EventArgs e)
{
string filePath = @"E:New ABCabc.vnalog"
if (!File.Exists(filePath))
{
return;
}
string SelectedFile = @"/select, " + filePath;
System.Diagnostics.Process.Start(@"E:New ABCabc.vnalog", SelectedFile);
}
Now this code open the .vnalog file in the application. And this works great..!!! How can I now change the path within the application?

I wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.
