Hi,
I meet a NO-Qt environment, where I have to use STL open and read/get
character by character from a file.
What I did:
_wfopen_s(&fp, fileName.c_str(), L"rb");
and
bool Source::get(wchar_t &ch)
{
if (!fp) return false;
if ((ch = getwc(fp)) == WEOF) return false;
return true;
}
It reads text files very well, but it cannot read through a binary file.
I guess it is stopped because WEOF is meet in the middle of a binary file.
Could you please help me out?
Thanks,
Lingfa

But a Qt-guy does not alway, or not only, works with Qt, right? So if someone can help, please help. Thanks, Lingfa -- [ signature omitted ]

Easy answer, applicable to this list, is of course to migrate your project to use Qt, and use all of it´s goodness to solve your file reading problems :-) QFile and QByteArray come to mind... If migrating to use Qt in your project is not an option, then the comments of the other posters in this tread come to mind, and this question belongs on another forum/list/group/channel/...

Another option is to rip the needed files out of qt and ship them with your application. Which only works if your application is in-house only or gets published under the gpl... If you want to stay C-only: Reading and writing files with C is bad... Doing so in plain-C++ with streams is a lot easier, but not quite as good as with qt. Anytime I try to stay within plain-C++, I switch to using Qt as soon as file-access is involved. ;-) Arnold -- [ signature omitted ]
