Can't read server log while server is open

[LewisH]

Hello, I've been trying to create a standalone windows application that reads the server logs, and forces all the players onto a specific team when a coop map is started (also resets when teams are balanced and prevents players from switching)

so far I've just been trying to find an efficient way to check for changes in the log file, then send the last line to a function.

Everything works fine when I edit the log file in notepad and save it, but the server launcher seems to always have to file open, and I can't read it using my application...

If I try to open the application when the server's already open, it gives me an error. If I open it before opening the server launcher, I see "{"port":-1,"time":0,"date":"2012 Jun 28 18:51:15:313 BST","type":"sessionStart"}", then it stops updating.

Does anyone know why this is happening, and how I can fix it? >.<

You need to open the file with the dwShareMode = FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE flags set.

see the documentation of the darkBASIC manual if thats possible.
if not, you need to import the function from kernel32.dll and call it directly
