Hello, all
how can I read out the file size of a spezified file by using OriginC (or maybe LabTalk) ??
(Maybe a new feature for global File I/O or the file class ?!)
Thanks
Hajo

Hi Hajo,
In Labtalk...
exist("file path\name")=; // returns file size in KB
In OriginC...
string strFile = "file path\name";
long fSize;
file ff;
ff.Open(strFile,file::modeRead);
fSize = ff.SeekToEnd(); // size in bytes
ff.Close();
-or-
string strFile = "file path\name";
long fSize;
WIN32_FILE_ATTRIBUTE_DATA fileInfo;
GetFileAttributesEx(strFile, 0, &fileInfo);
fSize = fileInfo.nFileSizeLow; // size in bytes

Hi Hajo, Mike, All,
Sometimes Origin C help files seem not to be as complete as
one could wish. Then it is useful to look into those header
files provided by the language, for instance "mswin.h" where
struct WIN32_FILE_ATTRIBUTE_DATA suggested by Mike came from.
It is amazing that we can find some examples there also.
That adds plenty of extra help to Origin C documentation.
Regards,
