I am building a log4net wrapper project where I reference log4net.dll. When calling this code through a static instance to log messages the new project also wants me to reference log4net.dll even though I have a reference to my logging project which in turn has the reference..

Code: void print(const std::vector<int>& vec)
{
for ( std::vector<int>::iterator itr = vec.begin(), end = vec.end(); itr != end; ++itr )
{
std::cout << *itr << std::endl;
}
}
My problem is as following.
I have an 2 arrays named: abee1 , abee2.
I have loop that want to call them one by one and print data of an them in each step. It means that I want to reach the name of arrayBee1 to arrayBee2 in the loop for printing its data. I made the name of each one by using strings ( abee1 , abee2) in the loop.
#include<iostream>
#include<string>
#include <sstream>
using namespace std ;
int abee1 [4] [4] = {{5,0,40,30},{6,0,21,47},{7,0,17,63},{8,0,31,62}};
int abee2 [4] [4] = {{1,0,37,52},{2,0,49,49},{3,0,52,64},{4,0,20,26}};

I know something is wrong with the "string *a = & arrayname;" part of code and after that.
concepts on pointers to structures and referencing for the following two lines.
//address of the variable "struct UIP_IP_BUF" is assigned as srcipaddr
uip_ds6_nbr_add(&UIP_IP_BUF->srcipaddr,
//data type "uip_lladdr_t" pointer points to the address of array an "nd6_opt_llao" with size UIP_ND6_OPT_DATA_OFFSET
(uip_lladdr_t *)&nd6_opt_llao[UIP_ND6_OPT_DATA_OFFSET]
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)
void func(float arg); // arg is supposed to be in type, with no referencing, just a copy of it
void func(float &arg); // arg is supposed to be in, out type, with something contained in it already
void func(float *arg); // arg is supposed to be in-out type, with nothing contained in it already and can be NULL
void func(const float& arg) // arg is supposed to be in type, with nothing contained in it already and cannot be NULL
Am I all correct?

#include <iostream>

void f(std::vector<int> const &v, std::vector<int>::const_iterator it = v.end()) {

f({}); }
prog.cpp:4:73: error: local variable ‘v’ may not appear in this context
void f(std::vector<int> const &v, std::vector<int>::const_iterator it = v.end())
Why is this not allowed? (I mean, what is the reasoning for defining the standard this way?)
In C++14/C++17 we will have a unified way to represent end iterators without an instance of the container, but currently I just have to hope my implementation accepts a default-constructed iterator as an end iterator.
I need to return taxes paid and net pay by pass referencing a gross pay overloaded function. Are the values returned from calling the overloaded function file stream objects? Can they be passed simply through a pass-by-reference function?
//Read Data from File, gather info and calculate pay, output data to file
while(counter < x) {
inFile >> last_name >> first_name >> hours_worked >> hourly_pay;
outFile << first_name << " " << last_name << " ";
outFile << calculate_gross_pay(hours_worked,hourly_pay);
counter++;
outFile<<endl;

We had to convert a single-line text editor which uses arrays to one that uses OOP and double-linked lists and I have been doing it in steps. I have, for the sake of convenience, put my headers, implementation and main all in one file.
I'm compiling this program in Hercules (the getch function uses C code).
I keep getting the error from the compiler saying "Undefined Symbol" for functions:
insertNode(char, Node);
deleteNode(Node*);
insertHead(char);
The full message is: ld: fatal: Symbol Referencing Errors. No output written to a.out collect2: ld returned with 1 exit status.

Basically I have a few tables in my Database.
So I have one table that is like so:
Item_ID, Name, Parent ID.
1 , jeff , 5
and another table like this:
Parent_ID, parent_Name
5,jackson
What I would like to happen, when I run my code is that I'll get the following
Item_ID, Name, parent_Name
1 , jeff , jackson
DataSet DS = new DataSet();
if (this.OpenConnection() == true) {
mySqlDataAdapter = new MySqlDataAdapter("select Item_ID, NAME, Parent_ID from table1, table2", connection);
mySqlDataAdapter.Fill(DS);
dataGridView1.DataSource = DS.Tables[0];
//close connection
this.CloseConnection();
}
So this spit out parent ID = 5.
I've not worked with Dataset before and I was just wondering what is the best approach? Can this be done via a SQL command or will I have to replace the value(5) with the string(jackson) using a large IF loop to search and replace.
I have code working, but that is largely because a vector that I am using as part of a structure that is the first of two elements of a MAP (with the second being an integer that is assigned later) is serving in its original, purely vector form, to fill out a set of selections on a DOS screen (option 1, 2, 3, etc.).
I do use the MAP, because it is a simple means of referencing the integer value using a word that is part of the structure, and is probably appropriate, saving me a search through the vector of words and calling up the value at the same location in the vector of words in a vector of corresponding numerical values. I DO feel that what I'm doing to produce the selection list is something of a "cheat" because I do not know how to access the same data within the structure component of the MAP by simply using a similar numerical reference (e.g. "MAP[1].structure.word", or would that be "MAP.structure.word[1]" ????) to print out the words in the structure in the map as choices on the screen.
I don't want to change or expand the contents of the map, just access and print each one in a simple loop with a number from the loop counter to the left of each word.
I have to do a project for Programming and he said in quotes
"Programming exercise 10.6: the programming project is as described, except do not represent the points using structures.
Assume, as known, the ten (x,y)-values corresponding to x=0.0, 0.1, 0.3, 0.45 ..etc and use y-values from the
function xsin(x); as in (x,y)=(x, xsin(x)) = (0.3, 0.3sin(0.3)).
Use value n+1=10, so the LaGrange polynomial will be order = 9."
What does it mean to not represent the points using structures??
I have project that is on c++. it runs fine. i want to use it in my C# application as a dll. i have created its dll and but firing exception of "interprocess communication".
Is this a doable task that creating dll of an exe project and using it in C# application?
At the moment im trying to integrate an dll in my project (first time).
I copy the lib and dll to my project-directory and the header to my include path.
Now i get a linker error:
1>LINK : fatal error LNK1181: cannot open input file "libWebSvcTx.obj"
the dll calls libWebSvcTx.dll.
I insert the libWebSvcTx.lib to the Dependencies.
Don't know whats the mention of the output and how to avoid it...

I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

View 6 Replies View RelatedI am writing a program that has many header files and their corresponding implementation files. I collected all the header files in a folder and did same for the implementation files into another folder. I'm using the Dev C++ IDE; I could add the files one by one to the project. Instead of doing this however, I tried adding the two folders to the project; but, the project did not compile!! The compiler could not find the files resident in each of the folders!
How I can add the folders to the project so that the internal files are visible to the compiler; or do I have to go the longer route of adding the internal files individually??

View 1 Replies View RelatedHere is the problem:"Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following:
a. Store the number as a positive integer.
b. Convert and store the number as a positive integer.
c. Print the number as a Roman numeral or positive integer as requested by the user.
The integer values of the Roman numerals are:
