hello experts,
I am developing a software and I need to create a couple of temp files
when
the program is running.
I need a piece of advice regarding the best place to put them:
- Windows\temp directory
- User directory
- Program directory
- ??
Needless to say, the directory must exist and the user must have the
appropriate permissions.
What are the good practices regarding this question ?
Thanks
Phil

I use this function:

CString GetTempFilePath(LPCTSTR strPattern)
{
CString csPath;
if(GetTempPath(_MAX_PATH,csPath.GetBuffer(_MAX_PATH+1)) != 0) {
csPath.ReleaseBuffer();
CString csTempFile;
if(GetTempFileName(csPath,strPattern,0,csTempFile.GetBuffer(_MAX_PATH+1))
!= 0) {
csTempFile.ReleaseBuffer();
return csTempFile;
}
}
return CString();
}

Also, I've discovered in some cases that where people were writing "temporary files" it
was because "the data is too big to keep in memory, so I have to write a file", and in no
case that I found for this was the file > 1MB! So unless you need to pass these files on
to a subsequent processing program, consider carefully if you need to write one at all.

I mostly write temp files when I'm trying to insert of exclude something
from a file. The best way I've found to do it is to create a new file, copy
the stuff I want from the previous file, then delete the original file and
rename the temp file to the original file name. I do a lot of this in
memory if the file isn't too big, but it's lots easier to just do it in temp
files (imo).
