Hi Antonio,

can you modifiy xBrowse to avoid the followin error,
1 - the user press the excel key in preview
2 - the xlsx file name request dialog appears
3 - if the user press ESC key or press button cancel
the error appears because oXlsx:cFile is empty

  

   if ( oXlsx := XlsxObj( cFileXls ) ) == nil   line 10859
      ? "Xlsx libraries not linked"
      return nil
   endif

   modify
   

   if empty( cFileNoExt( oXlsx:cFile ) )
      return nil
   endif

Dear Mauri,

I am testing it using the example I provided you for dropping files on the xbrowse:

#include "FiveWin.ch"

function Main()

   local aData := { { 10000, 235000, 90, 2115 } }

   XBROWSER aData SETUP BrwSetup( oBrw )

return nil

function BrwSetup( oBrw )

   oBrw:bDropFiles = { | nRow, nCol, aFiles | XBrowser( { nRow, nCol, aFiles } ) }

return nil

Are you able to reproduce this error on this example ? I am unable to do it.

Many thanks for your feedback :)

Hi Antonio,
happy birthday !

this is the test program

news that I had omitted in the initial post, the error happens when :
UseXLSXLIB(.T.), if i use excel to produce file the program work fine.

how to fix it :

ToXlsx( cFileXls, aCols ) CLASS TXBrowse

for each oCol in aCols <------------------------- line: 10870
WITH OBJECT oCol
AAdd( aStruct, { :cHeader, :cDataType, :nDataLen, :nDataDec } )
END
next

new code

for each oCol in aCols
WITH OBJECT oCol
AAdd( aStruct, { :cHeader, :cDataType, IF(valtype(:nDataLen) != 'U', :nDataLen, 0 ),;
IF(valtype(:nDataDec) != 'U', :nDataDec, 0 ) } )
END
next

in next step SetArrayData( aData, aStruct, aGroup ) CLASS TWorkSheet
AEval( aStruct, { |a,i| If( a[ 2 ] == "C" .and. a[ 3 ] > aSize[ i ], ; <--------------------------- line 531
a[ 3 ] := aSize[ i ], ) } )

the element : a[3] will take on the correct value

why oCol:nDataLen .or. oCol:nDatadec are undefined ?
These two property are opional, and if i use the definition of
the columns of the browse as type :

 
   *---------------------------------------------------------
   *- Column FIRST
   *---------------------------------------------------------
   

  ADD COLUMN oCol TO XBROWSE oBrw ;
      DATA      ("Client")->FIRST;
      PICTURE   "@!";
      TITLE     "First";
      ALIGN     LEFT ;
      SIZE      200.00

these two prop remain undefined

I would also add this piece of code to not proceed the file name is empty

 
 
   if ( oXlsx := XlsxObj( cFileXls ) ) == nil  <---------------Line 10859
      ? "Xlsx libraries not linked"
      return nil
   endif
   

   insert this new code 
  

if empty( cFileNoExt( oXlsx:cFile ) )
   return nil
endif

Thanks

Dear Mauri,

Ok, got it.

I have fixed it this way:

   if ( oXlsx := XlsxObj( cFileXls ) ) == nil
      ? "Xlsx libraries not linked"
      return nil
   endif

   if oXlsx:cFile == ".xlsx"
      return nil
   endif

many thanks!

Dear Antonio,

but in that way the problem still remains for not empty filename, empty filename is only a collateral problem.

Thanks
