Clarion in general: Getting subfolders into a queue
2004-04-03 -- Bjarne Havnen
 
Newsgroups: comp.lang.clarion

Below is some code I was forced to write because XP couldn't find a
particular file for me. This procedure calls itself recursively from a
starting directory.
This will not compile as is, since I also use a few global variables to set
if I should include subfolders. It should be a good start. Consentrate on
the Dirq part for your problem


SearchFiles          PROCEDURE (*File:Queue q,string searchpath,string txt)
! Declare Procedure
! Start of "Data Section"
! [Priority 5000]
DirQ Queue(File:Queue),Pre(Dirq)
 End
Scan Cstring(50)
SearchFor Cstring(255)

! End of "Data Section"

  If Sub(Searchpath,Len(Clip(SearchPath)),1)='\' !slash
     SearchPath = Sub(SearchPath,1,Len(Clip(SearchPath))-1)
  End
  If IncludeSubFolders
     SearchFor = Clip(SearchPath)&'\*.*'!*.tpw'
     Directory(Dirq,SearchFor,ff_:Directory)
  End
  r#=Records(Q) !number of records
  If Not FileTypes
     FileTypes = '*.*'
  End
  LastPos#=1
  Loop
     Pos#=Instring(',',FileTypes,1,LastPos#+1)
     If Not Pos#
        Pos#=Len(FileTypes)+1
        Do SearchDirectory
        Break
     Else
        Do SearchDirectory
        LastPos#=Pos#+1
     End
  End

  Loop I#=Records(Q) To R# By -1
       Get(Q,I#)
       If Not Instring('\',q.Name) !ikke no Directory()
          Q.Name = Clip(Searchpath)&'\'&Q.Name
          Q.Name = LongPath(Q.Name)
          Put(q)

  Recs = Records(Q)
  Display()

        SearchFor = Clip(SearchPath) &'\'&Clip(Scan)
        Directory(q,SearchFor,0)
