Hi Aaron,
Thank you very much.
I thought when I can seek to a perticular position and also I opened the file in
"fileModeUpdate"
mode I can just update at any file position. (Random Access) as follows.
theStream = FileOpen(0, filename, sysFileTFileStream, HLPRespXMLLibCreatorID,
fileModeUpdate, &err);
err = FileSeek(theStream, seekPos, fileOriginBeginning);
numObjects = FileWrite(theStream, text, (long) sizeof(char),
(long)(StrLen(text)-1), &err);
FileClose(theStream);
But, in reality, it looks like what you said, I need to use temporary file to do this
kind of update.
Thank you,
Chida
