file properties

[Sherak]

If I open a file with a program and I write another program which wants to open the same file, is ther a property I can check to see if the file is already open by another program ?.

thanks

That depends on OS and what mode your'e opening it in.
If you open it with write-access and no share (NT+) the second program trying to open it will fail, getting error codes indicating that file is taken by other program.

Look in the help for "CreateFile(...)", there is a thourough description on OS and sharing.
