Cvs files date field missing

I want to collect the dates of each filename. I am getting all the data of each filename except the dates. The date comes from the filenames like the building number. The building in the filenames are being stored with the other data except the dates. The filenames, for example, looks like this 100_2016-10-03_20-31.  The first three numbers are the building numbers, then the date, and the _10-31 is the time. How can I get the dates stored as well?  I have received an error message with this code that is in the program.                                   FOR lnI = 1 TO m.LnCnt
      LcDateStr= Chrtran (StrExact(laFiles.         [m.lnI,1],'_','_')
The error message was File 'strexact.prg' does not exist.
       LdFileDate = Date (Val (m.lcDateStr),Val(Substr (m.lcDateStr,6)),Val (Substr (m.lcDateStr,AT ('-',m.lcDateStr,2)+1)))
DO ImportFile WITH m.lcPath, laFiles [m.lnI,1], m.ldFileDate

 The error message was Function argument value, type, or count is invalid.

OR IF I use the code below, I get an error message saying, " File 'strexact.prg' does not exist", and Function name is missing.

This is the code that is being used.


Create cursor mycursor (;
                              Building N (3,0), ;
                              Item no i,;
                              Quantity I , ;
                              Description c (21),;
                              Date d)

* ---- Load cursor with CSV data.

Set order to building ascending

Lcpath = "H:\\Obra\Ldy\"

LnCnt = ADIR (laFiles, m.lcPath + m.lcFileMask)

Set century on
Set date American

LOCAL lcFileName, ldFileDate, LcDateStr

FOR lnI = 1 TO m.LnCnt
      LcDateStr = Chrtran (StrExact (laFiles[m.lnI,1],'_','_')
      DO ImportFile WITH m.lcPath, laFiles [m.lnI,1], Date (&lcDateStr)
SELECT Mycursor

Procedure Import File
LPARAMETERS lcPath, lcFileName, lcDate, lcFileMask
LOCAL lcLine, lnFH, lnBuilding, date, lcDateStr, FileName,

LnFH = FOPEN (m.lcPath +m.lcFileName)
IF m.lnFH > 0
   LnBuilding = VAL (m.lcFileName)
   FOR lnI= 1TO 3
          lcLine = FGETS (m.lnFH, 1000)
   DO WHILE !FEOF (m.lnFH)
         LcLine = FGETS (m.lnFH, 1000)
         LnA = VAL (LEFT (m.lcLine, AT (',', m.lcLine)-1))
         LcLine = Substr (m.lcLine, AT (',', m.lcLine)+1)
         LnB= VAL (LEFT (m.lcLine, AT (',', m.lcLine)-1))

         LcLine = SUBSTR (m.lcLine, AT (',', m.lcLine)+1
          LcC= ALLTRIM (SUBSTR (m.lcLine, AT ('"', m.lcLine)+1))
          LcC= LEFT(m.lcC, LEN (m.lcC)-1)
          INSERT INTO MyCursor (building, date, itemno, quantity, description) VALUES (m.lnBuilding, lcDateStr, m.lnA, m.lnB, m.lcC)

    = FCLOSE (m.lnFH)

First of all StrExact should be  STREXTRACT  (case does not matter but note two missing letters).
I'll write more but you may study this function in VFP help. The latest help version is available at

This processing loop should work:
FOR lnI = 1 TO m.LnCnt
      LcDateStr = Chrtran (StrExTRact (laFiles[m.lnI,1],'_','_'), '-', ',')  &&  this will convert the filename to a string, e.g. "2016,10,31"
      DO ImportFile WITH m.lcPath, laFiles [m.lnI,1], Date (&lcDateStr)   && which can then be used as a macro parameter in the DATE() function

Open in new window

A small update is also necessary in the INSERT command:
 INSERT INTO MyCursor (building, date, itemno, quantity, description) VALUES (m.lnBuilding, lcDateStr, m.lnA, m.lnB, m.lcC)
which contains lcDateStr invisible in this context

Correct command is:
 INSERT INTO MyCursor (building, date, itemno, quantity, description) VALUES (m.lnBuilding, lcDate, m.lnA, m.lnB, m.lcC)

where the lcDate is of date data type.
I've provided tested solution and my comments are explaining what was wrong in the original code. Lets wait a few more days for the author response.
The solution was tested and works correctly in my environment.
