Temporary Files

[Harsh Vardhan Singh]

hi,

i am trying to create a temporary file associated with a particular process.
For instance, i have a windows application which will create a temp file as
soon as it this program is executed. Now i want this temp file to be
destroyed if this application is closed / crashes. Is this possible?

Please help.
Thanks in advance,
Harsh

Does it need to be a physical file on disk?
If not, maybe you could use MemoryStream?

yes it has to be on the physical disk.. i think it wud help if i explain
what i am trying to do... basically i hv to prevent a file from being
accessed by two users (on different pcs) simultaneously.. so i want to
create a temp file as soon as one user accesses that file.. now when someone
else tries to open it, i first check if the temp file is present or not...

now the problem is removing the temp file in case the program crashes... coz
if the file is not removed then no user will be able to access it unless the
temp file is manually deleted.

this is why i wanted to know if there can be temp files created and
destroyed along with a process.

Does this help?

Here's a manage C++ example. Not perfect but helps a bit.

I believe I've done this with java before, but unsure how to do it in C#, so
I just googled it. I still have to finish reading the article myself
(sorry), but I'll do that when I get my coffee (right now :>).

HTH.

If you need to create more than one file, then you can use
TempFileCollection class found in the System.CodeDom.Compiler namespace.
On MSDN (installed locally) you can find out more at

HTH,
