I have the header (and accompanying lib file) in my project folder, I have it in my solution explorer. And I've tried to add it via C++ Directories.. but that doesn't seem to exist anymore, instead it points to a user property sheet, but where to find or access it ...
I have a main.h file where I include all the needed things to make my program compile properly, string, vector etc.
And I also have another header file which comntains a class that is used later in the code (globally), I decided to keep it in another file to make it more clear and easier.
I need to include that file in main.h, but I also include main.h from that class header file because it contains some other includes that are required to compile.
Is this a good thing? Or should I keep main.h out of that class header file and include just things required for the class?
I may have complicated it too much, so I'll show an example, what I do now:
// ---- main.h ---- #include <string> #include <vector> #include <ctime> // other includes, these are just examples #include "MyClass.h" // the separated class header file
[Code] ......
So, from what you can see MyClass.h requires just including the vector, but to avoid repeating myself I include main.h which does that already, but also includes MyClass.h
So, I have two questions: 1. Is it ok to include in that way (including a file that includes the including file) 2. Is it good to include a main header file with all the includes even if I just need one of them, or should I skip including main.h and include just the things my class requires (vector is just an example)
I am currently developing a small quick'n dirty SIP (Session Initiation Protocol) parser. Its task is to read a file (or command-line argument) with a SIP requst and parse it using the sofia-sip library. It should exit either with "1" on parsing failure or "0" on parsing success.
I have taken the code snipplet from here: [URL] .... resulting in this source code:
I have two report.h files located in two different directories. However the contents of them are different. How can I include the report.h file located in guarddog into the report.h file located in sky?
I have defined to classes : Parent and Child. I have some global variables in a header file named as "var.h". These variables are used in both Parent and child Classes. The source code of these classes are written below:
Parent.h ============================================== #ifndef PARENT_H #define PARENT_H #pragma once #include <stdio.h> class Parent {
[Code] ....
After compiling, the compiler returns a fatal error as follows:
1>Parent.obj : error LNK2005: "int counter" (?counter@@3HA) already defined in Child.obj 1>C:Documents and SettingspishiDesktop estDebug est.exe : fatal error LNK1169: one or more multiply defined symbols found
It says the "counter" is defined multiple times....
For a while, I have been running a Windows 7 Visual Studio 2012 CPP project fine. However, today, all of a sudden, it has stopped being able to read any header files that are in relative directories. I cannot think what I have done to make this happen.
It seems to be an issue with Visual Studio as a whole, rather than my individual project, because I have created a new simple project and I am having the same problem. So, I have a CPP project at `C:/Projects/TestProject`. Then, I have a header file called `test_header.hpp`, which is located at `C:/Headers`. In `TestProject`'s project settings, I have added the directory `../../Headers` to `Additional Include Directories`. Then, my main functions is as follows:
Code: #include "test_header.hpp" int main() { return 0; }
Which gives me the error:
Code: Error1error C1083: Cannot open include file: 'test.hpp': No such file or directoryc:projects estprojectmain.cpp11TestProject
Is there some global Visual Studio setting that is responsible for setting up these relative directories? Just in case the relative directory was not correct, I also tried a load of others, such as `../Headers` and `../../../Headers`, but these gave the same errors.
I have four source files. The main source file includes two other source files. The two other source files both include the fourth source file. In the fourth source file I have an include guard. Will the code from the fourth source file exist in two locations in the compiled code? Is this something that is compiler dependent? An example of this is shown in the code below.
I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
I was created a dynamic library (Used win32 App) & compiled with no error.
Then i was created my main application (MFC) & paste the .h,.lib,.dll files from the source path(dll App Path) to destination path(Main App Path). If i used the below command in my app means the project working good.
Code: #include "Alg.h" #Progma Command(lib, "VTAlg.lib") & also paste the VTAlg.dll in my app path.
here Alg.h contains the some methods , In future i will edit the function like below for my client requirement but no function name & Arguments change. The changes made in inside function(Logically changed) only.
My client contains only .exe file + .dll file.
My requirement, So after change the method i will send only .dll file to my client
If i change my lib file name VTAlg2.lib instead of VTAlg1.lib (But Same Function name & Arg type)means how can i edit the code below
Is it possible to add a MFCToolBar to the header of a MFCPropertySheet because every page which will be dynamically added during runtime will be using the same toolbar and if it IS possible I would much rather do it this way instead of putting the same toolbar on every page. I have enabled the header with height of 48 and have implemented the MFCToolBar code first in the constructor then in OnCreate. It does not generate any errors during compiling or at runtime however the toolbar does not show.
I wanted to share the value of a variable from Sender Program to Receive after program and want to calculate difference between send and receive. After studying Header file concept I program following three.
Now I am struck. How to to compile? I link all these file. I used following method:
Then I run Sender and after that Receiver.I per my knowledge, Receiver should give difference but it gives error :
Code: Receiver.c: In function "main": Receiver.c:10:42: error: "Send" undeclared (first use in this function) printf(" Total Receive is %d ",Receive-Send);
Code: Sender.c #include <stdio.h> int Send ; void main(){
I have been working a project in C++. I have TTTMain.cpp file that has all the function calls, TTTFuntions.cpp that has all the functions, I have TTT.h file that has all the prototypes and variables and additionally I have Winner.h that has enum class Winner declaration in it. Here is my block of codes:
Winner.h file:
#ifndef winner #define winner enum class Winner {
[Code]....
My question is when I compile this gives me error on
Now i want to convert this into a unsigned char pointer.
unsigned char * pBMPHeaderData;
I already got the raw image data in another unsigned char buffer.
unsigned char* pRawBMPData;
Now i want to make a complete BMP image by adding the header info and raw data into a new unsigned char pointer. For this i need to convert the BITMAPINFO struct into a unsigned char *
im trying to compile a project that uses Open SSL but i have a problem since compiler complains about this on some headers
The files are empty and only containing this line:
"../../crypto/md5/md5.h"
I understood that those headers redirect to the actual file in a different path from the include folder, must work in other compilers but VS2013 complains about it.
Im planing to work arround it like copying those files directly in the include folder or even take the time to redirect those includes to the actual file one by one but im guessing that there is a simpler way.
