I've forgotten how to include a path to a folder from my current directory!
I mean, instead of loading my dice images as "dice6.png", I'm trying to load them from a file, as ".Imagesdice6.png"
Not sure why, but this isn't working. Google searching has got me nowhere.
#include<iostream>
#include<conio.h>
#include<fstream>
#include<windows.h>
using namespace std;
int main(){
string ptr,a;
string b="E:project";

I have built the wave tool and now am trying to run my source code through it. But it just doesn't want to find the include directory. I just don't understand. Here's my command:
#include <stdio.h>
#include <vector>
#include <map>
#include <string>
Perhaps it how I built it since there is no info on how to do this? I just ran ../b2.exe from the boost_1_53_0/tools directory.
I'm running CYGWIN_NT-6.1-WOW64 TARDIS 1.7.18(0.263/5/3) 2013-04-19 10:39 i686 Cygwin with a g++ version of 4.5.3. g++ has no problem finding the default include directory (I don't have to specify the -I switch). The -I switch doesn't seem to work for any of the other include directories that I wan to use either, but I want this cleared up before I get into that since it might be related.
im trying to write a file to a default document folder..something like...
FILE* file;
file = fopen("%docdir% est.txt", "w");
fputs("Hello", file);
fclose(file);
"%docdir% est.txt" this isnt working for me, i have to write it as
"C:userspublicdocument est.txt"
any method to write directly to default document folder so it will work in most Windows ? for example in windows 7 this is the default folder "C:users publicdocument est.txt" in windows XP its different
i have to detect the windows version first, to write the correct path
This question is currently only for windows; but I would like to know about a cross-platform way to perform what I want to do (explained below) -
I have created a little program:
#include <iostream>
int main(int argc, char *argv[]) {
for (int i = 0; i < argc; ++i) {
std::cout << argv[i] << '
';
} }
I have added this program to the windows PATH. I put this program in C:Program FilesProgram
I now navigate to C:DataVariousTexts using CMD.
Then I type in: "program x"
The program will print out "program x" as by default. What I would like to get hold of is the folder in which the program is actually being called. ( I want to somehow get "C:DataVariousTexts" to be read into my program ).
How do I perform such an operation?
I'm trying to output only a few files, using regex, from the current directory, this is my main code:
Code:
// main.cpp
{
char * _dir = new char[MAX_PATH];
getcwd(_dir, MAX_PATH);
unique_ptr<CExtractor> _ptr(new CExtractor(_dir));
delete[] _dir;
}
Code:
// CExtractor.cpp
DIR *pdir = NULL;
struct dirent *pent = NULL;
pdir = opendir(_cwd.c_str());
while ((pent = readdir(pdir)) && (pent->d_type != DT_DIR)) {
if (regex_match(pent->d_name, regex(".(in|txt)$"), std::regex_constants::icase)) {
cout << pent->d_name << endl;
}
}
closedir(pdir);
My code is compiled correctly, but when I run my binary, nothings is outputed..here are my files in the current directpory:
aclocal.m4 config.guess config.status depcomp m4 NEWS

I am currently working on a program that will take an image and compare it with all other images in the current directory and sub-directories. I decided to use Qt for this as Qt has a QImage class with an overloaded == operator. This seems to work well if there are duplicates of the same size.
However, my goal is to not only find duplicate images of the same size, but the same image which may be a different size. To do this, I shrink the larger image to the size of the smaller image using the QImage scaled function.
The concern I have with this is that the scaling isn't done the same way the smaller image may have been scaled. I tested this by shrinking a copy of a picture in Paint, that image does not get deleted. I believe that == is looking for an identical image, so when I do the shrinking (via that scaled function), even if it is of the same picture I shrunk in Paint, the two methods of shrinking are not identical, and so the images appear different.
Any better method I can try? Something that can allow for slight deviations, such as an image being 99% "the same" as another. (I admit here that I will need to define some metric for what "the same" means.) In this case, the method assumes they are "identical" and gets rid of one of them.
The main way I can think of doing this is to go through each image, one pixel at a time. If the two pixels from the different images at the same index are the same, then I can increment a same pixel counter. If this number is 99% (or some other threshold) of the total pixel count, I can make the assumption the images are the same.
I'm writing a small function that gets as parameter a file's path and a folder's path, and copies the given file to that folder.
Code:
int copy_file(const char* source, const char* folder) {
char copy[PATH_MAX];
strcpy(copy, folder);
strcat(copy, "/");
strcat(copy, source);
[Code] ....
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...

How to create a directory / folder.( to browse/save my files to a directory.) how to specify the path?
I googled , but i cant able to find appropriate as it is showing all in the C#, C++ , objective C. But not in C.
Here i am writing a sample program to my POS device .problem here is it is not taking mkdir(direct/dir.h header file)function. Any alternative is there to make a directory?
I quite often use an ide written in assembler: RadAsm3[URL] .....
It has a menu item to explore current path. I have used other ide's that have a similar feature but:
The one in RadAsm3 will activate a current Explorer window if the current path is the same as the one requested.
All others open a new Explorer window.
I would like to implement the RadAsm3 approach using Visual Studio 2013 Community c++ as my host compiler for testing.
I tried to get the title of current windows but it appears ShellExecute "explore" does not produce a conventional window???
there's a way to get a path to the recycle bin folder for a specific drive for the current user?
Say, on the input one provides "C:" and on the output you get "C:$Recycle.BinS-1-5-18"
The following code is useful to allow a user to select a particular folder in the disk directory.
Code:
void OpenFolder() {
LPMALLOC pMalloc; //,pMalloc2;
CString strDirectory;
BROWSEINFO bi;
// Gets the Shell's default allocator
wchar_t pszBuffer[MAX_PATH];
[Code] ....
However, if one uses this code over and over, one quickly becomes tired of threading one's way all the way from root directory C:. There is undoubtedly some way to designate a starting directory. The most obvious candidate to set such a target is the:
Code:
bi.pidlRoot = NULL;
But attempting to set bi.pidlRoot to a CString (directory address) errors because 'no suiitable conversion from CString to LPCITEMIDLIST exists'
How can I set the code to open at a designated address in the directory tree?
I have tried to use File.Copy and File.Move but non of them would work as I expected .....

I am trying to include a function from a header file named headerfunt.h . The code of my header file is
Code:
#ifndef HEADERFUNCT_H_INCLUDED
#define HEADERFUNCT_H_INCLUDED
#include <iostream>
[Code]....
But, while compiling it says abs was not declared... I have included the file.
I'm not sure if I was some weird syntax problem or the way Ive ordered things. But a conditional statement I have created is not performing the way I want it to.
else if ( !( xDif == -1 && yDif == 1 && prevXDif == 1 && prevYDif == 0 ) )
{
foundArr[lastX][lastY] = 1;
}
When debugging, the condition was activated with the values:
xDif = -1
yDif = 1
prevXDif = -1
prevYDif = 0
However, I want the condition not to follow through as I am using the 'NOT' or '!' operator to negative the entire statement. For some reason, the line of code within the else if is still running.

In io.cpp file, should I put the two statements ("include <iostream>" and "using namespace std") at the top, outside of the functions?
Or should I put the two statements inside each of the functions?
I'm a beginner with C and wonder how to include single header files (*.h) in to my project. I mean header files which are not included to the standard installation package.
I thought it would work if I just copy the newheader.h file in to library folder c:MinGWinclude, but it didn't work. Is there some kinf of GCC -command or procedure to add these single header files or how it should work?
All of those standard header files are working well and I don't have any problems with them.
Environment I'm using is MinGW+GCC+Win7.
