I want to test if a file is locked. Is there a quick and easy way to do that?

Hi,

you can use this

If OpenFile(1,"c:\test.txt")=0
    MessageRequester("Open", "File already in use", #MB_OK|#MB_ICONERROR)
EndIf

OpenFile fails (returns 0) if the file is opened for read/write access.

correct, as purebasic does not use the shared flags by default, so it wants to open the file exclusively

Well, I'm going to use copyfile() - trying to figure out under which conditions that might fail
