Hi all,

I would like to delete from a directory all the files that match: bar*.*
I know that I could do for instance: system("del bar*.*"), but this will
bring up the command prompt window and as my app is a winmain app this
wouldn't be nice. I could use DeleteFile, but you can not use wildcards
in this one.

How could I do this using Windows functions?

Thanks in advance,
Viv

Hello,

You can either use "SHFileOperation" with FO_DELETE flag set in the
SHFILEOPSTRUCT structure or browse the directory deleting files that match
your expression using "PathMatchSpec" function.

Regards,
Arno

Hi, Viviana

Have a look at Directory.GetFiles method. You can get list of files using
mask and then delete them using standard File.Delete method.

Use FindFirstFile() and it's siblings to get the file names and then
DeleteFile().

Thanks for the answer. I have tried using SHFileOperation and it works,
but I still have a problem.

I want to delete the files named: file.log.1, file.log.2, ...,
file.log.x, _but_ not to delete: file.log

If I use "file.log.*" in pFrom, also the file.log will be deleted. How
can I avoid this?

Thx in advance,
Viv

In cmd, I regularily do

ren yyy.log xxx
del yyy.*
ren xxx yyy.log

Every program has at least one bug and can be reduced by at least one
line. By induction, then, every program can be reduced to a single
instruction, and that will be wrong.

Method 1: Enumerate the files yourself and detect when you shouldn't delete.
Method 2: Temporarily add ReadOnly-attribute or lock the file that shouldn't
be deleted.

Are you sure it will delete file.log ?
It shouldn't, there is no point after the filename...
Anyway, you may want to use generic character '?' that can replace ONE
character...
.... and try "file.log.?"...

Did you test that? I would claim that you have to inform shellexecute that
the REN command is inside CMD.exe .. that is "cmd /c ren .....". Also,
i can't see why ShellExecute() couldn't be used as well.
