C++ :: Rename Failed With File Name Had Space / Hyphen After Unicode Support
Nov 12, 2013
I intent to use this mechanism for rename the file because the file name consists Unicode characters . I would like to know why the return value of "MoveFileExW" is false for file name consists 'space','hyphen' etc.(sometimes even without a Unicode character).for accepting 'space','hyphen' what type of conversion I would use [I.e.: Does the root cause of failure is due to CP_UTF8 type use].
Code:
//! inputPath & final_inputPath consist source and destination file name and are std::string
//! Both are in same directory F: est_files
std::wstring unicode_input_original;
int unicode_input_length_original = 0
[Code] ....

I had a file which has name like SIRAO.wav Since this file name has special unicode character all file API's are failed.
I would like to rename this file using Windows API. How can achieve this?
std::string filename variable hold this value as SIRÃO.wav.
I try to read the file using file API after perform a conversion.
Code:
const int utf16_length = MultiByteToWideChar(CP_UTF8,0,filename.data(),filename.length(),NULL,0);
std::wstring utf16;
utf16.resize(utf16_length);
MultiByteToWideChar(CP_UTF8,0,filename.data(),filename.length(),&utf16[0],utf16.length());
const wchar_t *name = utf16.c_str();
rename the file with unicode character?

How to rename a textfile in a Visual C++ CLI GUI project. I've tried using the 'rename()' function but that isn't working for me (probably because of the type of project).

I have this code to check if file exist already and its work, but what i need is : is to add feature to function to see if the file already exist open same file and rename it with another name ,probably file2
assume file name is "abc.c"
This scenario like this
User>>(provide file name)
Code>>(check if file already exist show msg:
"File already (abc.c) exist would you like to create another file and rename it ("abc2.c") "maybe it need loop to search directory "????
User>>if press yes ok it will make another file with another name but if no exit the function and dont create another file
Code: // function to check file existence and here what i need to add the feature above
int fExist(const char* fn){
struct stat buffer;
int exist = stat(fn,&buffer);
if(exist == 0)

I have some code that was compiled without Unicode turned on in the Preprocessor Definitions. I need to access an API that had Unicode turned on in the Preprocessor Definitions (I believe that it is on by default for DLL's) .
I need to call a function in the DLL that requires a structure like:
struct READERINFO {
TCHAR serial[32];
TCHAR altSerial[32];
TCHAR name[32];
TCHAR fccId[48];
TCHAR hwVersion[16];
int swVerMajor;
int swVerMinor;
char devBuild;
};
It returns some information in the structure some of it is Unicode based however the program that is calling it is not Unicode. The preprocessors are not turned on because if they were there would be a lot of things to change in this code. The code is old code that I inherited and now I must interface to some new devices.
I declare my structure as :
READERINFO info; Then I call the function in the DLL which looks like: ApiGetReaderInfo(hAPI, &info, sizeof(into));
Which is defined as:
ApiGetReaderInfo(HANDLE hApi,
Struct READERINFO * ri,
DWORD riSize);
Parameters:
hApiHandle to valid Api object instance
riPointer to the READERINFO structure.
riSizeSize of ri structure in bytes. Usually: sizeof(struct READERINFO).
When I call it from my program that does not have UNICODE defined in the Pre-Processors I get :
Characters like : ÌÌÌÌÌ in the TCHAR fields and invalid numbers in the integer fields.
int ModuleVersion(HANDLE hApi) {
struct READERINFO info;
ApiGetReaderInfo(hApi, &info, sizeof(info));
[Code] ....
When I call it from my program that has some sample code just for this and has the UNICODE defined in the Preprocessors it works just fine. how I can call this from my old code and get the correct information. I have already tried to do the follow without success:
int ModuleVersion(HANDLE hApi) {
#define UNICODE
struct READERINFO info;
#undef UNICODE
ApiGetReaderInfo(hApi, &info, sizeof(info));
[Code] .....

I have a.h as follows
namespace one{
namespace two{
enum Filter {

If I do this in another header file b.h
#include <one/two/a.h>
namespace one {
namespace three {
}
}
I get error 'n' does not name a type.

I am facing an issue of file open failure after CopyFileW.
I suspect that some of the handle which is part of copy is still holding the file.
How can i wait till the OS handle free the file.
Any API's available to check this ?

I need to store in a file names that will have letters like "ăĂâÂșȘțȚîÎ"
wchar_t name []=L"ăĂâÂșȘțȚîÎ";
FILE* fang;
fang= _wfopen( L"test.txt",L"wt+,ccs=UNICODE");
fwprintf (fang, L"%ls ",name);
When i open my text file i get this: ??âÂ????îÎ
if i use
fang=fopen("test.txt","a");
I get the same result
and for
fang=fopen("ang.txt","a,css=UNICODE");
I get a runtime eroror "invalid file open mode"

I need to read Unicode characters from a file. The only thing I need to do from them is to extract their Unicode number.
For example if file has u I need to extract its corresponding Unicode number.

How to open a file which its name is unicode letters ? usually :
Code:
basic_ifstream<wchar_t> src("source.txt");
Work well to read file with unicode content not filename, so that example doesn't work :
Code:
basic_ifstream<wchar_t> src(L"source.txt");
Also, I have seen some alternatives for using open function but it doesn't work as well.
Code:
basic_ifstream<wchar_t> src;
src.open(L"source.txt");
I use g++ compiler.

How do I output a Unicode number if I extract a character off a console or out of a file.
If I do the below, I use the Unicode number to show a character. The below shows me 25² .
char b = 'u00B2';
mystring = "25";
mystring.append(1,b);
How do you go back the other way? If I extract the 25 and the ² separately, how do I get the unicode number for ² ?

I have a problem, caught the last line of a file and do the division of the same variables in, date, time and value, but the file contains excess spaces in all lines and the date is coming with cuts, example 24/4/2014 appears 4/4/2014. How can I remove the space in the string without affecting the division of the line?
if (file) {
std::string line = getLastLine(file);
std::istringstream iss(line);
getline(iss, date, ' ');
getline(iss, time, ' ');
getline(iss, t); //variavel para temperatura em string
}
else {
std::cout << "error file
";

I want to write a c++ code that due the structure of file space allocation,Simulates file system with 2*n array. Each column represents a sector. The first row is for storing files And second row holds the address of the next sector (Number of columns). And With each click on keyboard Create a file with random size and automatically find Appropriate sectors by using disk allocation method (or index allocation)... Also File names should be asked from user... And we should have file table Where the starting address of each sector,file extension and file size is given..

For some reason my compiler says "rename not declared in this scope" .... Isn't it declared in iostream? Or is rename only for C not C++? And if it is only for C how do I rename a file in C++ then?
#include <iostream>
#include <cstdlib>
using namespace std;
int main(int argc, char* argv[]){
char oldname[] = "RomeTW.exe";

I used rename function to rename a file.
The file names are in std::string type variable.
The function usage is like this
int result = rename (old_file_name.c_str(),new_file_name.c_str());
I expected result = 0 but i get result = -1.
Does this return code is due to any file pointer holding to this file?

I have source code that is shared between two compilers, one supports TR1 and one doesn't. I've reverse engineered a few of the TR1 templates for the older compiler, but I need to be able to detect whether TR1 is supported or not, so as to include the correct header.
Something like this.
Code:
#ifdef SUPPORTS_TR1
#include <array>
#else
#include "mystl/array"
#endif
std::array<int, 10> myarray;
The compiler that supports TR1 is Visual Studio.

Question is : Write a program that opens a file and counts the whitespace-separated words in that file.?
my answer is :
#include <iostream>
using namespace std;
#include <iostream>
#include <string>
#include <fstream>
int main() {
string filename = "Question 1.cpp"; // File name goes in here
[Code] ....
Now I am not sure if im suppose to get a msg saying : The file "Question 1.cpp" has 0 words.
im wondering is the question that im being asked, asking me to input a string of words and then the compiler when it builds and runs the program counts the word spaces.?

I am having a datagrid view. In that suppose I give the header name as wrong, suppose say, instead of "test", i gave it as "tst". So i need to rename in this case. So what i expect is I need to double click that header and rename it. But in code I can't directly give it as "test", since it can be whatever. By double clicking i need to change in that display itself. I can able to catch the double click event. It is as below. Any code which makes me to edit and rename the header.
private void dgvParametersEdit_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
}

I am working on a database project, which can store (initially) 10,000 marksheets with following capabilities
1) new entry
2) edit/modification of entry
3)delete entry
4) separate Departements ( BBA, BCS, M.Phil, Phd., etc.)
5) can store data on files ( initially, all data is stored in a single file)
Now, I want to create a menu, in which i can use arrow keys to navigate through the menu and use Enter key fo selection.
What should i use in it?? The project is only on C language.

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.
