Help with file creation and deletion...

If have two simple procedures..

Begin
FileCreate('newfile.txt');
FileListBox1.Update;
End;

and.....

Begin
DeleteFile('newfile.txt');
FileListBox1.Update;
End;

Assuming nothing else is done. (I'm never opening the file just
creating it) How come the DeleteFile won't work?

Thanks - Joe

Make sure you're in the right directory. Try passing the filename and path
to DeleteFile.

Re:Help with file creation and deletion...

These are two calls that my program needs to make getting the file name
from user input. It WILL work if I try to delete a file after just starting
the app.

If I create a new file, without quiting, then the delete does not work. I need
to quit the app then restart to be able to delete the file.

Seems like delphi 3 thinks the files open or something??? Yet it won't
let me 'close' it either.

Re:Help with file creation and deletion...

Are you turning I/O check {$I-} off somewhere? If you are, I think that even the
modern Delphi (pascal) versions require you to make this test also:
if IOResult = 0.
Without using it, the next IO-operation seems to get lost somewhere.
