Programatically Change Attributes of Windows File with Wild Cards (*.jpg) in VFP - attributes

Question

Hoping to use a windows shell API call that can accept wild cards to change attributes programmatically. Utmost thanks/blessings for any/all thoughts.
Borrowing code from http://www.resolvinghere.com/sm/how-do-i-change-an-attribute-of-a-file-from-within-a-visual-foxpro-program.shtml
RUN /N ATTRIB +H "c:\test.txt" && Hidden causes dos window to noise itself
RUN /N ATTRIB -H "c:\test.txt" && UnHidden
Tom recalled this ... but it does not take wild-cards:
*------------CHAR-------HEX------------------BIN---------NUM

Of course RUN ... should not be one of your selections to accomplish a procedure where you don't need to shell to DOS at all.
Your question is two fold:
How do get a list of files using a wildcard + in all subdirectories.
For this one you can use a bunch of alternatives such as FileSystemObject, Adir() or Filer.dll that ships with VFP and maybe more. Here I will sample with the Filer.dll (which is also the DLL used in HOME()+'tools\filer\filer.scx' ). Here is one enhanced wildcard match using filer:
*GetTree.prg
Lparameters tcStartDir,tcSkeleton,tcCursorName,;
tlSubfolders,;
tlWholeWords,tlIgnoreCase,tlSearchAnd,tcSearch1,tcSearch2,tcSearch3
Create Cursor (m.tcCursorName) ;
(filepath m, filename m, ;
FileSize i, fattr c(8), createtime T, lastacc T, lastwrite T)
Local oFiler, lnFound
oFiler = Createobject('filer.fileutil')
With m.oFiler
.SearchPath = m.tcStartDir
.FileExpression = m.tcSkeleton && Search for skeleton
.Subfolder = Iif(m.tlSubfolders,1,0) && Check subfolders
.IgnoreCase = Iif(m.tlIgnoreCase,1,0)
.WholeWords = Iif(m.tlWholeWords,1,0)
.SearchAnd = Iif(m.tlSearchAnd,1,0)
.SearchText1 = Iif(Empty(m.tcSearch1),"",m.tcSearch1)
.SearchText2 = Iif(Empty(m.tcSearch2),"",m.tcSearch2)
.SearchText3 = Iif(Empty(m.tcSearch3),"",m.tcSearch3)
lnFound = .Find(0)
For ix=1 To m.lnFound
With .Files(m.ix)
If !(Bittest(.Attr,4) And .Name = '.')
Insert Into (m.tcCursorName) ;
(filepath, filename, FileSize, fattr, createtime, lastacc, lastwrite) ;
values ;
(.Path, .Name, .Size, Attr2Char(.Attr), ;
Num2Time(.Datetime), Num2Time(.LastAccessTime), Num2Time(.LastWriteTime))
Endif
Endwith
Endfor
Endwith
Return m.lnFound
Function Num2Time
Lparameters tnFloat
Return Dtot({^1899/12/30}+Int(m.tnFloat))+86400*(m.tnFloat-Int(m.tnFloat))
Function Attr2Char
Lparameters tnAttr
Return ;
IIF(Bittest(m.tnAttr,0),'RO','RW')+;
IIF(Bittest(m.tnAttr,1),'H','_')+;
IIF(Bittest(m.tnAttr,2),'S','_')+;
IIF(Bittest(m.tnAttr,4),'D','_')+;
IIF(Bittest(m.tnAttr,5),'A','_')+;
IIF(Bittest(m.tnAttr,6),'E','_')+;
IIF(Bittest(m.tnAttr,7),'N','_')
How do I set the attributes.
If you are not after those fancy attributes, that are rarely used, here is the function I have written for myself:
*SetFAttributes.prg
lparameters tcFileName, tlReadOnly, tlHidden, tlSystem
#define FILE_ATTRIBUTE_READONLY 0x00000001
#define FILE_ATTRIBUTE_HIDDEN 0x00000002
#define FILE_ATTRIBUTE_SYSTEM 0x00000004
local lnNewAttr
lnNewAttr = iif(m.tlReadonly,FILE_ATTRIBUTE_READONLY,0)+;
iif(m.tlHidden,FILE_ATTRIBUTE_HIDDEN,0)+;
iif(m.tlSystem,FILE_ATTRIBUTE_SYSTEM,0)
declare integer SetFileAttributes in Win32API ;
string # lpFileName, integer dwFileAttributes
declare integer GetFileAttributes in Win32API ;
string # lpFileName
return ( SetFileAttributes(#tcFilename, ;
bitor(bitand(GetFileAttributes(#tcFilename),0xFFFFFFF8),m.lnNewAttr)) = 1)
Having the above prg files on hand, lets say you want to set all .txt files under c:\MyFolder and its subfolders to readonly, (not hidden, not system) you would be doing this:
Local lcFileName
GetTree('c:\MyFolder','*.txt', 'myCursor', .T.)
Select myCursor
scan for Atc('D',fAttr) = 0
lcFileName = Addbs(Trim(FilePath))+Trim(FileName)
SetFAttributes(m.lcFileName, .T., .F., .F.)
