C++ :: Unicode Support For Windows Renaming API?
Nov 7, 2013
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?

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

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));

If I rename a control, when I build, I get an error because deep in the code, the old name exists, but my rename doesn't change the old name. Am I doing rename wrong? (I just go to "Name" in properties and type the new name.)
Same idea with control deleting. So I add a control (textBox, label, whatever). I later decide to delete the control. When building, it still has code for the old control and won't let me proceed.

I am writing a C++ program that finds the Word Documents on your computer that have '+' or "%2B" in the name and replacing those '+' and "%2B" with ' '. I am writing this program for my school's University Writing Center, so I predict the only places they will have these files are the USB memory stick, Desktop, Documents, and Downloads. I encounter a problem, however, when I run this program and it renames the files in Downloads: Permission denied. I am using the windows.h to do this. How do I give the program permissions to that folder?
update:This program is going to be written in C++.

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.

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.

Is it possible to use a CFormView as the main view without using document support. IE pointing CWinApps m_pMainWnd to the CFrameWnd derived MainFrame and attaching the CFormView from there. It does not seem to be working and I was wondering before I waste any more time on the solution if it is even possible. I know it is an easy solution if I create a true SDI application however I have no use for documents in this application.

I wrote a program that use a struct to represent an athlete. The program allocates memory for an array of 5 Athletes, and, soon after I enter the fourth data (height) for the first athlete, I get the message "runtime Error R6002 - floating point support not loaded". The program doesn't reach the line where __LINE__ would be printed.
Code:
#include <stdio.h>
#include <stdlib.h>
typedef struct athlete {
char name[ 100 ];
char sport[ 100 ];
double height;

I am struggling with how to efficiently design my class objects to support the outlining of a collection of items. The collection would be sorted but would also have the ability to indent and outdent individual items representing a Parent and Child relationship (see attached).
An item could indent up to 5 levels deep. A summary level would be considered a Parent while items below the summary level would be consider as children.

You told me that it's better to use UNICODE all the time.
What if the Win32 Api function doesn't have a UNICODE version.
For example CryptProtectData() takes a BYTE (DATA_BLOB *) which is an unsigned char?

I'm writing a school assignment that writes/reads user input into and out of a binary file.
I've gotten the write part to work, but now I need to be able to read that file back in and display it as a string.
I think I should be using fread() and read my file into an array of int's right? But when I try printing out that array I get a whole bunch of numbers that don't match the hex code in my file.
How do I read in a binary file and print it out as a string?

For example if using FindFirstFile(...) it assumes your passing LCPWSTR and not LPCSTR.
I know I can use FindFirstFileA or FindFirstFileW so what is point of default if always UNICODE.
Which brings to my second question. If I say
FindFirstFile("C:", &fdat);
I get error cannot convert parameter 1 from 'const char [7]' to 'LPCWSTR'
I could say WCHAR fName = "C:"; and pass this variable instead. However is there a way to cast "C:" on-the-fly to LPCWSTR, I tried,
FindFirstFile((LCPWSTR)"C:", &fdat);
But it outputs a stream of LONGs to the console instead of filenames.

I have a problem when i try to save unicode to a .txt file.
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.

I'm having some problems in receiving fileNames from Server to Client(C++) in Mac OS X. I send a serialized object , which has a char pointer with the fileName or sometimes a string object, when i receive it in the client, it seems to be having %F6 or %E9 ,etc . This issue don't arise in Windows OS though, even thought it's the same code. Is there anyway decoding these '%' characters back to their original form in Mac OS & Linux ..?
Fex characters i got into problems with : ǡ ȅ ȉ
It would be difficult to change the code in server, so if there's a way decoding the characters back to its original form, it would be easier.I'm using Boost Library for Serialization and i'm just looking for ways to decode %F6 back to ȅ in C++, like if some library is available ..?

Been trying to configure the GridView to display ony 4 rows of data at a time. I thought it wasn't working because I forgot to set AllowPaging to True, but after I did that, I just get the error of
The data source does not support server-side data paging.

Here is my Books.aspx.cs code:

Am I missing anything or doing something wrong thats not causing it to page & only display 4 titles at a time?

I'm trying to write a simple Delegate class with a Bind() and Invoke() function. For now it only needs to support a void class function with no parameters. I've searched around and found quite a few exmaples, though, those class are heavily templated and I lose track trying to simplify it.
So far my code is following:
Code:
#include <windows.h>
class Test {
public:
void DoSomething() {
MessageBox(NULL, L"Test::DoSomething!", NULL, 0);
[Code] ....
The part I am having difficulty with is assigning &Test::DoSomething to the m_Callback variable.
&tObject::DoSomething works, yet _Callback which I pass &Test::DoSomething to does not work.
Also, why does the following line work:
Code:
m_Callback = &Wrapper<tObject, &tObject::DoSomething>;
When wrapper is like:
Code:
template<class tObject, void (tObject::*Func)()>
void Wrapper(void* Object)
Should it not be Wrapper<class-typename, parameter-1>(parameter-2) // This currently creates an error

I am trying to write data in Russian language to the serial (RS-232) port. My display device is already set to that character code page.
But output on the device is not exactly what I require.
My code snippet is like this below
CString pBuffer = L"английский"; //Russian Language
LPBYTE pByte = new BYTE[pBuffer.GetLength() + 1];
memcpy(pByte, (VOID*)LPCTSTR(pBuffer), pBuffer.GetLength());
long nBuffer=pBuffer.GetLength()+1;
DWORD dwWritten=0;
WriteFile(pHandle , pByte, nBuffer ,&dwWritten , NULL);
pHandle is a valid handle.

I just wonder whether 0xFFFF is a valid Unicode character.
When I using the following code:
CStringW strTempW;
CString strTemp1;
INT_PTR nLen;
strTempW.Format(L"%c", 0xFFFF);
nLen = strTempW.GetLength();
strTemp1 += strTempW;
nLen = strTemp1.GetLength();
After executing the first codeline strTempW.Format(L"%c", 0xFFFF), I will get strTempW of length 1, but cannot see it first character in Visual Studio watch window.
After executing the codelilne strTemp1 += strTempW, I will get strTemp1 of length 0.
Whether 0xFFFF is taken as a valid Unicode or not?
