uCharToVal returns "01/01/2020" as 20/09/0090

Hi Rao,
Is my usage of uCharToVal() wrong?

Code: Select all

#include "fivewin.ch"

proc main()
  set century on
  set date british

  ? uCharToVal("01/01/2020", "D")
return
 

The above snippet gave result as 20/09/0090.

Compiled with Harbour+FWH1912

TIA

? DToS( CToD( "01/01/2020" ) )

We will look into the function.

The bug is fixed in version FWH2005 to be released.

You can make this correction and test.

In the module \fwh\source\function\valtostr.prg:
please replace the existing
static function dCharToDate( cDate )
with the following revised function:

Code: Select all

static function dCharToDate( cDate )

   local cFormat, cc, cfmt
   local dDate

   if ( cc := Upper( cDate ) ) != Lower( cDate )
      return dAlphaToDate( cc )
   endif

   if Len( cDate ) >= 8 .and. IsDigit( SubStr( cDate, 3 ) ) .and. IsDigit( SubStr( cDate, 5 ) ) .and. ;
      ! Empty( dDate := SToD( Left( cDate, 8 ) ) )
      return dDate
   endif
   if Len( cDate ) >= 10 .and. IsDigit( SubStr( cDate, 3 ) ) .and. !IsDigit( SubStr( cDate, 5 ) ) .and. ;
      !IsDigit( SubStr( cDate, 8 ) ) .and. ;
      ! Empty( dDate := StoD( Left( cDate, 4 ) + SubStr( cDate, 6, 2 ) + SubStr( cDate, 9, 2 ) ) )
      return dDate
   endif

   // check for single digit date/month
   if !IsDigit( SubStr( cDate, 2 ) )
      cDate    := "0" + cDate
   endif
   if !IsDigit( SubStr( cDate, 5 ) )
      cDate    := Left( cDate, 3 ) + "0" + SubStr( cDate, 4 )
   endif
   //

   cFormat  := Lower( Set( _SET_DATEFORMAT ) )
   dDate    := CToD( cDate )
   if Empty( dDate )
      cc    := Left( cFormat, 2 )

      for each cFmt in { "dd/mm/yy", "mm/dd/yy", "yy/mm/dd" }
         if !( Left( cFmt, 2 ) == cc )
            SET( _SET_DATEFORMAT, cFmt )
            if !Empty( dDate := CTOD( cDate ) )
               EXIT
            endif
         endif
      next

   endif
   Set( _SET_DATEFORMAT, cFormat )

return dDate
 

We'll be glad if you can test and let us have your feedback.

Hi Rao,
Yes I got the expected result with the fixed version.

Thank you
