how do I import the stripped export names (no mangling) from C code
A functions int Func()
is exported by def file to MyDll.dll
LIBRARY
EXPORTS
Func
Now if I import from another source Func by providing
exyern "C" int Func()
/lib:MyDll.lib
I get error error LNK2019: unresolved external symbol Func referenced in function main

Which compiler is best for these purposes?
I need a code for renaming multiple(bulk or all ) files in a folder.
I found one batch file script but it renaming with numbers only. But i want differntly.
[URL] .....
Example:
In a folder there are 100 images and all numbered with some digits or names.
assume that all images are belongs to "john" , so i want to rename all images with "john+ a random string".
here a random string means -> it has an array with 3000 english words, (you can predefine them by downloading from dictonary).
In the script the 3000 names are fixed, but the 1st name will be changed by my wish. that my be john, mary, sai, pavan etc...
Suggestion: you do not need to enter all 3000 words in array manually. some javscript codes are there to read input of each and evey line and them into an array.
i have a vector of stores. i would like to delete the specified choice(store) from the list. Here is what i have but my erase statement is wrong and wont compile.
void Store::deleteSpecifiedStoreFromList(string choice) {
for (int i = 0; i < this->stores.size(); i++) {
if(this->stores[i].getStoreNames() == choice) {
this->stores.erase( std::remove_if( this->stores.begin(), this->stores.end(), choice ), this->stores.end() );
}
}
}

The bit that's giving me issues is the "calculatedetails" function, where an mp3 file is opened in binary and then an array of chars is filled with the binary data.
The problem I'm having is that I want to be able to read the constituent bits of the characters in, so that I can find the mp3 frame headers (12 1's in succession)
I'm aware that the section I've added in to perform this is incorrect.
This code will show the data from the .txt file "file1" the data is (0.0 0.1 0.2 0.5 0.8 0.9 1.0)
What I'm trying to do is take these float values and add them all up and divide them by 7 (finding the average and output that) Convert it into a percent and print it in a field:
Width of 6 with 2 digits after the decimal point...
I tried doing something like cout << "the average is: " << data/7 << endl; but that didn't work. I got an error that said "/" was not an operator.
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ifstream myfile("file1.txt");
string data;
getline (myfile, data);
cout << data << endl;
myfile.close();
return 0;
}
I already have this but I sense I'm missing something so I'd like to be pointed to a proper article/document on this sorta thing.

I am trying to take a Text File mydata.txt and import it into a structure however when I try to run this code it just closes out.

struct hard_disk{
char name[18];
double size;

Essentially what I need to do is take a text file, ("input.txt"):
4 4
1 0 0 1
1 1 1 1
0 0 1 0
0 0 1 0
And take the first two values on line 1 (4, 4) and use them as length and width.
Number of rows: 4
Number of columns: 4
Then I need to print out the matrix and further manipulate it. I need to find the sum of the 1's per column and then take that number and replace each 1 with the 1's in each column.
So it'll look like this:
2 0 0 2
2 1 3 2
0 0 3 0
0 0 3 0
The part that's mostly troubling me is that my instructor will be giving me the input file with random values, so I don't know what the matrix dimensions will be.
I can read the 2D array but can't seem to use it after. I need to find a way to skip the first line, and then read in the matrix and be able to use it mathematically to add up each column.
I'm trying to add a function now that lets the user open 1 or more files and import them to the database and dataGridView. Now the way it is now (should) work. But when it has finished with FILE1, it won't add FILE2 as it then gives me an error that the Column Date Already exists.
My code is below
private void btnOpenLog_Click(object sender, EventArgs e) {
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "Log Files (*.log)|*.log";
openFileDialog1.Multiselect = true;

private String[] GetExcelSheetNames(string excelFile) {
OleDbConnection objConn = null;
SqlConnection objSqlConn = null;
System.Data.DataTable dt = null;
try {
[code].....
Now I can fatch all the excel sheet belongs to the Excel File.But How can I check "If and Only If the sheets are havin Underscore in their name(eg. student_data,teachers_data) then only the data of the sheets will populate in tha data base"
I am trying to create an array of file names such that when I want to open one of the files, who's name is given in the array, I can call that element of the array. My code for making the array is the following,
Code:
char file_name[40];
char *file_locations[N]; // array of N names (*)
for(ii=0; ii<=N-1; ii++){ // printing the names of all the files P1_8mag_1.txt - P1_8mag_N.txt
sprintf(file_name, "P1_8mag_%i.txt", ii+1);
[Code]....
The problem with this is that in the first step: all elements of the array "file_locations" are the name of the last file in the loop (in this case "P1_8mag_N.txt")What is wrong with this?
I have an assignment that needs to display the names of customers to be served according to a sequence. coding to display the names accordingly?

I have .db3 file, and he has 14 tables,and every table has certain number of columns. Example i have table called "BASIC_INFO" and that table has columns "First Name", "Last Name" and "Age".
How can i get name of table and name of every column,so if i some day add column "Male" i get name of this column too. I need first to calculate number of columns,put that in some integer, and then for example create string array which will contain : array[0] = "First Name" ,array[1] = "Last Name"...
SQLiteConnection myConn = new SQLiteConnection("Data Source=" + DB3Path + ";Version=3;New=False;Compress=True;");
//string query = "Select * From " + DB3Path + ".INFORMATION_SCHEMA.COLUMNS";
string query = "Select * From BASIC_INFO.INFORMATION_SCHEMA.COLUMNS;";
SQLiteCommand sqCommand = new SQLiteCommand(query);
[Code] ....
I tried this too:
string query = "select * from INFORMATION_SCHEMA.COLUMNS"
+ "where TABLE_Name='BASIC_INFO'"
+ "order by ORDINAL_POSITION;";
string query = "SELECT TOP 0 * FROM BASIC_INFO";
I have encountered errors when trying to display the customers' names in a priority queue.

So I been asked to write a program that does the following:
Write a program that allows the user to enter a series of 10 names from the keyboard and then sorts and prints the names in alphabetical order. Use a series of functions:
1) Input the data
2) Sort the data (use a bubble sort)
3) Print the data
After this is done, allow the user to enter a name from the keyboard and determine if the name appears in the list. Use a function to accomplish the search. The name to be searched for should be input within main and sent to the function as an argument.
4) Search the data (use a binary search of type bool)"
this is whats I wrote so far and its giving me error with the sorting and the searching, I need to fix it and I cannot figure out how?!.
#include <iostream>
#include <conio.h>
#include <string>
using namespace std;
void bubbleSort(string[], int);
int main()
[Code]....
I cannot manage to get the code for sorting the names in alphabetical order.
#include<stdio.h>
#include<string.h>
typedef struct{
char criminalName[10];
char criminalCase[20];
[code]....
The point of this code is to get 15 names and then hash them. After one name is entered I get a segmentation Fault and the program crashes.
Code:
//driver file
#include <iostream>
#include <vector>
#include <string>
using namespace std;
[Code] ....
I am doing a homework assignment. I do not want the complete answer, just a hint. I have to load a file of names into an array, display the names, then sort the names alphabetically, display them again, then list how many names start with certain letters. I have everything done but how to display how many names start with a certain letter.
Here are the names:
Collins, Bill Smith, Bart
Allen, Jim
Griffin, Jim
Stamey, Marty
Rose, Geri
...........
And here is the code I have so far.
Code:
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
#include <algorithm>

View 1 Replies View RelatedI'm trying to read a C code, but there are functions including CLASS word at the titles of functions. Is it a correct implementation?
For example: double CLASS getreal (int type)
What is the meaning of CLASS in titles of functions in C? I could not find such an usage in my C book?
