How to check, if a file is locked by another application? [message #7245]

Hi all!

I need to read in some text files and parse them. These text files are transferred by ftp.

For reading them I found two solutions:

LoadFile(...)

and

FileIn in(...)

if (in)
...

But I have to prevent my service to read files, which are not finished (to transfer). So what happens with "LoadFile" or with "in" when file is still in progress? Is there a way to check, whether a file is "locked" by another application or not?

Thanks in advance,

WebChaot.

Well you can use FileStream instead of FileIn and use
::Open(const char* filename, READWRITE | NOREADSHARE | NOWRITESHARE)

[Edit: ] you can use FileStream(const char* filename, READWRITE | NOREADSHARE | NOWRITESHARE) , too

this way you try to open the file exclusive.
