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.
I'm trying to have a button marked by the sqrt sign, '√'.
I wrote below code and typed that sign by holding down "alt" and typing 251 using numpad. But result is the question mark instead of sqrt mark!

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 ..?
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'm trying to print Chinese/unicode characters to a line printer(EPSON LQ-2090) using the writePrinter method in c++.
ANSI characters print fine, but when I throw the buffer of widechar Chinese characters at it, they come out like garbage/ANSI chars.
while debuging string shows chinese characters but in memory it shows ANSI characters not chinese and these ANSI characters are get printed on printer.
Note that if I change the DocInfo datatype parameter to "TEXT" instead of "RAW" then also the Chinese characters donot print.
Is there a way to get Chinese or unicode characters to print correctly?
if i start reading individual characters from a text file having the following content: "music, Indian classical dance, and other aspects of Indian culture.It is also a movement with chapters in over 200 towns and" what are the characters that will be read after the word 'culture.' ?

I get this data from a site and I copy paste them to create a .txt file for input (I do this my self, no program involved).
When the program runs it ends up like this on netbeans:
0 [main] program 2336 open_stackdumpfile: Dumping stack trace to program.exe.stackdump
When I type the input file my self it works fine. When I copy the data from the site that the problem occurs, it looks like those strange characters are causing the problem (notice the ????? are some drawings on text).
I searched for a code to read characters from file and i found this one
#include <stdio.h>
#include <stdlib.h>
int main() {
char ch, file_name[25];
FILE *fp;
printf("Enter the name of file you wish to see

but when i run it, and give the path of file in the cmd, this appears
stack around the variable 'file_name' was corrupted
given that i put the path in cmd as shown

I think it comes from having to align the data in the output file. How to start this is to use a function to read in all the characters using a while loop. Then read in all the digits in a separate function. When it comes to outputting the data in the correct format I'm lost, so for now if I could figure out the functions that would be awesome. A final note we have not gotten to using strings so the I'm trying to use getc, fgetc, and ungetc.
Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a students first name, then one space, then the students last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be the same as the data in the input file except that there will be one additional number at the end of each line: the average of the students ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings. Use formatting statements to make the layout clean and easy to read.
I need to open a file that has multiple lines that look something like this, " black box 100.01 33.5 78.93". What this shows is the coordinates of the black box. Lines will have different objects with different coordinates. I need to create a loop that will read this file and tell me when a black box is found by displaying a message. I don't need to know how to create this file. I don't need to display the entire file but rather have it search for black boxes.

The program takes a file "test.txt" and reads it, replaces the characters above with the corresponding strings, and then writes the output to "scrubbed.txt".
A sample input would be: <something>

So the plan is to create a word search by reading in characters from a file into an array. This is my code so far, nowhere near finished but have encountered a problem already:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define ROWS 20
#define COLUMNS 20
int main()
{
[Code]...
My question is to do with the section highlighted in red... I can't really see why it is not printing out my array (wordsearch), it's probably very basic but I have no C experience so am not too confident in what I'm doing.
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 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 have a string which is n characters long. i need to read say 20 characters at a time, wait for the user to type OK and then send another 20 characters. wait for the user to type OK and send 20 characters again until we get to the nth character.
View 3 Replies View RelatedHow 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 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

This program is suppose to read a matrix file , and the first getline is suppose to get the file header but it appears that 'line' doesn't take in any value other than empty thus causing all the problem , I tried to put cin.getline() in front of it to take away the /n created by the cin before it , but it doesn't work . When I debug the program when the arrow points to the string line , this error appears
line<Error reading characters of string.>std::basic_string<char,std::char_traits<char>,std::allocator<char> >
I tried to initialize string line=NULL too , doesn't work either.
may i know how do i read a string 2 characters at a time?
lets say i have a for loop like this
for(int i=0;i<stringLen;i++)
{
for(int j=0;j<???;j++)
{
//insert code
}
}
what i want to do is i want to read a string 2 characters at a time and store them into a vector.
Simple program to convert files to XML files. However I am trying to narrow down why my code is not working. I am reading a line that looks like "2001 Joe Dirt Los Angeles", then the next few lines are followed by text and the the fifth line looks like "---End of Description---".
So here is the file
2001 Joe Dirt Los Angeles
Home is where you make it
Best movie ever(but not really)
But seriously
---End of Description---
Here is example code to test the process
string line;
while(dataFile >> line) {
getline(dataFile, line);
cout << line << endl;
}
My returning output is
[space]Joe Dirt Los Angeles
[space]Home is where you make it
[space]Best movie ever(but not really)
[space]But seriously
My test code is skipping the date on the first line but replacing it with a space. Then it is skipping my fifth line which reads "---End of Description---". Now if I take the code out of the while loop and hard code in five lines of output (x5 getline(dataFile,line); cout << line << endl;) then my code works as expected. I get all of the information. Date and the fifth line.
It looks like when I am testing for the EOF it is also taking in the numeric value at the beginning of the first line. However, that does not explain why it is dropping that fifth line.
I have been skimming and searching but dont know how to word the search just right to find what I need to know. I have written simple stuff with the support of tutorials like weight conversion or loops counting up to a set number. Nothing amazing. The other day I found out how to input and print a string rather than a single text character which i though was bad ass. I even got it to read multiple strings on a single line and found a way to read multiple lines. I can even format it to read both integers and characters on the same line as long as I know the predefined format.
On to my question... How do I read multiple lines with both carecters and integers. for instance:
nissan 1996
toyota 1998
or more comples like
nissan gtr 1996
toyota markii 1998
I want to use
int year;
char make[10]; maybe need to use char make[10][10]; for an array i would guess.
char model[10]; optional for the extra data
but reproduce what i read in a different order. say...
1996 nissan
1998 toyota
vice the original format.
this is what I have tried.
Code: scanf("%s %s", &make,&year);
//The way I seen to read multiple lines was on here
scanf("%[^/t]", %make);
But this wont let me separate the two into two differnet definded data types. Let alone use printf to display them in reverse order.
I'm new with C language. I got task to do . Actually there are 2 points. Both should be done with reading text from file. write down all letters from text in reverse alphabetic order (each letter 1 time).write down all words in random order.
I'm stuck with first point. Below code gives me entire text, but i need unique characters only. Text file contains few sentences.
Code:
#include<stdio.h>
void main( ) {
FILE *in;
int ch;
if ( (in = fopen("test.txt", "r") ) != NULL ) {
