==== Lock on OS file (OpenInsight 32-bit) ====

Hi



I am using an OLE navigator control to display an image file, the process will eventually require an osdelete on that image file. If another user is presently displaying that same file, the osdelete fails with status 5 (Unknown error) - presumably because the OS has a lock on that file.



So I am looking for a method to determine if the file is locked at OS level before displaying it, to prevent such behaviour. Has anyone dealt with this before and if so are you willing to share your solution?



Thanks,

Nick

I think OsOpen will do it for you




<code>
OSOPEN file to hfile then

   osClose hfile

    isDeletable = true$

end else

    isDeletable = false$ 

end



if isDeletable then

  osDelete file

end
</code>
