Hi all,

I have a function, as follows:

void __fastcall TMainForm::DeleteAllFiles(void)
{
char szb[500];
char szc[500];

SHFILEOPSTRUCT shfo;
shfo.hwnd = GetDesktopWindow();
shfo.wFunc = FO_DELETE;
wsprintf(szb,"%s%c%c",DirList->Strings[HOMENETWORK],0,0);
shfo.pFrom = &szb[0];
wsprintf(szc,"%s%c%c",DirList->Strings[HOMELOCAL],0,0);
shfo.pTo = &szc[0];
shfo.fFlags = FOF_NOCONFIRMATION | FOF_ALLOWUNDO ;
SHFileOperation(&shfo);
}

DirList is a string list with directory names in it, the problem is the line

wsprintf(szb,"%s%c%c",DirList->Strings[HOMENETWORK],0,0);

copies a directory name, say "c:\temp1" into the pFrom string, when I
call the SHFileOperation it deletes the "c:\temp1" directory. What I
would like to do is delete all its contents but leave the directory intact.

I could generate a list of all the files and folders in the directory
and delete them individually but I was wondering if there was an easier
way to do it, i.e. by modifying the code presented above.

Any thoughts

Thanks

Joe

Have youtried specifying a file mask, ie: "c:\temp\*.*" ? Have you tried
applying the FOF_FILESONLY flag?
