directory delete

[butthead]

Is there a function to delete a directory
including subs. Sort of like a complement to
the forcedirectory function. I will otherwise
have to give myself a refressher course on tree's.
I guess I could use a while loop to repeatedly
got thru an array but I see nothing but ugly in
that method. I have no problem deleting all files
in the directories.

I use the find functions to add directories to an
array then go thru the array and delete all files.
I could use a sort to arrange the items in descending
order starting with the subdirectories farthest from the base. I guess my question is which is the preffered
method.

Sort, Tree, whileLoop, other.

Thanks for all your help.

Somewhere I have seen a recursive operation for deleting subdirectories. I'll look around and see if I can find it.

I'm using the function below to get the directories loaded into an array. I then use a for loop to delete the files in each directory. what I attempt to do now is use a similiar loop to delete each directory.
The problem Im having is that when I delete the directories there is always one directory left over.

int RecurseDir (char *dir, char *wild, int x)
{
// Loads the directoryarray

struct ffblk ffblk;
int done;
char buff [512];

strcpy( buff, dir );
strcat( buff, wild );

done = findfirst(buff, &ffblk,
FA_DIREC + FA_SYSTEM
+ FA_HIDDEN + FA_RDONLY + FA_ARCH);

while( !done )
{
if(strcmp(".", ffblk.ff_name) != 0 &&
strcmp("..", ffblk.ff_name) != 0)
{
if((ffblk.ff_attrib & FA_DIREC)
== FA_DIREC)
{
// process directory
strcpy(buff, dir);
strcat(buff, ffblk.ff_name);
strcpy (directoryarray [x], buff);
strcat(buff, "\\"

x++;

x = RecurseDir(buff, wild, x);
}
else
{
//
}
}

done = findnext(&ffblk);
}

return x;
}

in this function The last deletedirectory process always returns an error but the directory name posted to the richedit is correct. I,ve been pulling my hair out for a week and I know that the problem is so simple that it is completely invisible to me.

void ClearBackupDirectory (char *targetdir)
{
char *buff1 = new char [256];
int x = 0;
int y;
int z = 0;

// Delete the files in base of the backup directory.
EmptyDir (targetdir, x);

strcpy (buff1, targetdir);
strcat (buff1, "\\"

y = RecurseDir (buff1, "*.*", 0);

for (; z < y; z++)
{
EmptyDir (directoryarray [z], x);
}

for (z = 0; z < y; z++)
{
if (!RemoveDir (directoryarray [z]))
RichEdit1->Lines->Add (&quot;Error deleting directory&quot;
RichEdit1->Lines->Add (directoryarray [z]);
RichEdit1->Lines->Add (&quot;&quot;
}

delete buff1;
}


Any help would be appreciated.

As usual when I give up the answer appears.
Ive seen it happen so many times that I have
come to expect it. The answer came the day
after I posted this thread. I was looking for
the cause in the find function. I forgot that
my erase files function changed to the selected
directory first and then deleted the files.
Of course the last directory could not be deleted.
thats the directory I was currently in.

on another note, I was suspecting that I would
have to create a tree structure to properly
delete the directories from the subdirectories up.
I noticed that the recursedirectory function
loaded the array from the top down. It occurred
to me that if I just started from the last directory
listed in the array and proceeded to the first,
the directories would be deleted in the proper order.

chdir (homedir); // the program start dir
for (z = y - 1; z > -1; z--)
{
if (!RemoveDir (directoryarray [z]))
{
ProgressForm->RichEdit1->Lines->Add (&quot;Error deleting directory&quot;
ProgressForm->RichEdit1->Lines->Add (directoryarray [z]);
ProgressForm->RichEdit1->Lines->Add (&quot;&quot;
}
}

I should be finnished with a beta soon and I
would like some peer review. I would hope some
will give me some critic when I have it posted.

Thanks all of you for all the help.
