Reading a unicode names from a file???

[zlatko]

Show us a piece of actual code

[darpan]

FILE *fp = NULL;
HEADER_FILE Header;
HEADER_FILE *SearchHeaderStart=NULL,*SearchHeader=NULL;
memset(&Header,0x00,sizeof(HEADER_FILE));
QString CurrentPath=QDir::currentDirPath ()+"/HeaderFile.cfg";


fp = fopen((const char *)CurrentPath,"rb");
if(fp!= NULL)
{
while(1)
{
if(feof(fp))
break;
if(!SearchHeader)
SearchHeaderStart=SearchHeader=(HEADER_FILE*)callo c(1,sizeof(HEADER_FILE));
else
{
SearchHeader->next=(HEADER_FILE*)calloc(1,sizeof(HEADER_FILE) );
SearchHeader=SearchHeader->next;
}
fread(&Header,sizeof(HEADER_FILE),1,fp);
memset( SearchHeader,0x00,sizeof(HEADER_FILE));
QChar SoftwareName[260*2];
memset(SoftwareName,0x00,260*2);
memcpy((void*)SoftwareName,(const void*)&Header.bSoftwareName,(260*2));
QString Name(SoftwareName,260);
QMessageBox::information(0,"Software Name",Name);



Following is a Structure to read data from a file Header.cfg in which data is written According to following structure and we have to read this structures from this file and make a link list but when i am displaying the Header.bSoftwareName then get the first character of softwareName right but how can i get the whole name because the name is written in unicode in .cfg file.
typedef struct tagAppendHdrFile
{
tagAppendHdrFile *next;
char bSoftwareName[260*2];
char bFileExt[260*2];
}HEADER_FILE;

First of all use CODE tags for showing your code..also why you dont use QString instead of char *, QFile istead of FILE, and something like QPtrList istead of using pointer on next item in your struct

Thanks and regards

If you were using Qt classes, you wouldn't have this problem.

QChar SoftwareName[260*2];
 memset(SoftwareName,0x00,260*2);
 memcpy((void*)SoftwareName,(const void*)&Header.bSoftwareName,(260*2));

QChar SoftwareName[260*2];
 memset(SoftwareName,0x00,260*2);
 memcpy((void*)SoftwareName,(const void*)&Header.bSoftwareName,(260*2));

To copy to clipboard, switch view to plain text mode 

QChar is a class --- it isn't safe to initialize it using memcpy. Not mentioning that &Header.bSoftwareName is char **.

This might work:

QTextCodec *codec = QTextCodec::codecForName( "UTF-16" );
QString name;
if( codec != 0 ) {
   name = codec->toUnicode( Header.bSoftwareName, 2*260 );
}

QTextCodec *codec = QTextCodec::codecForName( "UTF-16" );
QString name;
if( codec != 0 ) {
   name = codec->toUnicode( Header.bSoftwareName, 2*260 );
}

It really helps if you try to read the documentation before asking a question.

Look at QFile, QTextCodec and QTextStream.
