View 5 Replies View RelatedVisual C++ :: Getting Unicode From API DLL Using Non-Unicode Program
Aug 29, 2013I 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));

C :: Translate Pthreads Into OpenMP
May 20, 2013I'm quite new to openMP, mostly used pthreads and mpi before. Now I like to tinker a bit with openMP, but haven't found any good docs, reference list or similar.
What's the equivalent to pthread's mutex lock in openMP?
Code:
#pragma omp parallel for
for(i=0; i<n ; i++){
// Do something intelligent...
// If needed handle a shared variable.
}
How do I protect the shared variable?

C++ :: Increase Char Code Doesn't Work
Jun 11, 2014Code:
#include <iostream>
using namespace std;

char character = 'a';

the point of this code is to increase character by 1 (so from a to b in this case).
The line highligted in red is the line that the system is rejecting at the moment (but there may be other issues). why it is invalid?
C++ :: Debugging Code (Displaying Char String Per Character)

C++ :: Concatenate Two Char Arrays Into Single Char Array?
Sep 29, 2014I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?

C :: Parsing Char Array To Array Of Struct To Process Packets
May 28, 2013I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.
decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.
whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?

C/C++ :: Printing Out Unicode Hex As Chars
Feb 10, 2014I'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?
C++ :: Is UNICODE Enabled By Default In VC++ Express
Feb 25, 2014For 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.

C++ :: Decoding Unicode Characters To String
Jan 6, 2013I'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 ..?
C++ :: Unicode Support For Windows Renaming API?

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?

C++ :: How To Send UNICODE Characters To Serial Port
Jul 17, 2013I 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.
