Re: Excel/POI - Here We Go Again

Peter,
I'm the one who dragged it from my desktop to the IFS so the fact that I 
wasn't testing for read rights didn't seem important. But I added that to 
the existing 'access' existence test and the 'open' still returns a ZERO 
'book' address.
Thanks.

Re: Excel/POI - Here We Go Again






Arthur,

did you check whether you have sufficient rights to the XLS file?

I include the following in my programs that read spreadsheets:

     d   ExcelName     s           1024a

     d Access          pr            10i 0 ExtProc('access')
     d                                 *   value options(*string)
     d                               10i 0 value

      /free
         Select;
         When access(%trim(ExcelName):0) < 0;
           Msgdta = 'Stream file not found.';
           SndPgmMsg(MsgDta);
         When access(%trim(ExcelName):4) < 0;
           Msgdta = 'No read access to stream file.';
           SndPgmMsg(MsgDta);
         Other;
      /end-free

Excel/POI - Here We Go Again






All,

Now that I've got an actual s/sheet back from a salesman in the field, the 


problems begin again. The HSSF_OPEN proc is failing as below. 

The statement is: book = 
HSSF_open(/bq_budgets/inbound/dayton/B7_DAYT_S001_STEVETWAMLEY_C7.xls); 
(This s/sheet definitely exists in the IFS. I used a CPYFRMSTMF to copy it 


and it worked fine.) 

Strangely, the 'open' returns an address of ZERO for 'book' but does not 
halt. The exception occurs only when the HSSF_GETSHEET fails because the 
'book' address is 0.

Can anyone please help? Management believes I can read in all 295 s/sheets 


we sent out!! (And I don't want to disabuse them of the notion).
Thanks.

Note the odd wording in the "Unable to construct record instance" line.
